VCS Environmental provides CEQA/NEPA, Regulatory, Biological & Cultural Services 30900 Rancho Viejo Road, Suite 100, San Juan Capistrano, CA 92675 | 949.489.2700 vcsenvironmental.com
on identifying presence or absence of BUOW, suitable burrows and/or burrow surrogates for BUOW, and any other sign of BUOW within the Study Area as shown on the attached Figure 3.

No BUOW or signs thereof were observed within the Study Area during the surveys. Based on the lack of any direct or indirect evidence of BUOW presence, the survey results indicate that the Study Area was not occupied by BUOW at the time of the surveys.

Project Information
The Project is located in the City of Ontario, County of San Bernardino and consists of two Assessor Parcel Numbers (APNs): 021-815-148 and 021-815-110 (“Project site”) totaling approximately 47.69 acres, including offsite improvements in the surrounding right-of-way (“Project Footprint”). The Study Area includes an additional 500-foot buffer zone surrounding the Project site. The Project site is regionally accessible from State Route 60 (SR-60) and Haven Avenue to the north, and from Interstate 15 (I-15) and Ontario Ranch Road to the southeast [Figures 1 and 2; Regional Location and Aerial Map, respectively].

The Project Footprint is generally flat with elevations ranging from approximately 770 to 790 feet (234 to 241 meters) above mean sea level (MSL) (Google Earth 2021).

Past Biological Survey Efforts
The West Haven Specific Plan (2006) described the previous onsite biological resources as follows:

The Program EIR prepared for the City’s NMC General Plan Amendment states that the Sphere of Influence is currently dominated by agricultural fields, dairy operations, pastures and croplands. Remnants of native vegetation are virtually absent. According to Küchler’s (1977) map of the potential natural vegetation of California, the Sphere of Influence area was historically dominated by coastal sage scrub vegetation. Windrows are prevalent along the internal roadways. Areas of intensive agricultural industry such as feedlots and permanent cattle holding pens are generally devoid of vegetation. The Program EIR further states that the Ontario Sphere of Influence area has been greatly altered from natural conditions, under the influence of intensive agriculture and dairy industry. Despite these continuing land use practices, the Sphere of Influence area supports a diversity of wildlife, especially that of birds. This is due, in part, to the relatively level topography that 1612

Due to the presence onsite of Dehli sands, Dehli Sands Flower-Loving Fly (DSF) focus surveys were conducted within the West Haven Specific Plan area (URS, 2006) in 2002, 2003, 2005, 2007, and 2022 (Larry Munsey International, 2002 & 2003; Goodlett, 2005, 2007, & 2022). All of the surveys conclude that DSF did not occupy the site due to a lack of suitable habitat.

Site-specific surveys were not conducted for PAs 1 and 3, as their unsuitable habitat did not warrant focused surveys. Concurrence with this conclusion was received from the US Fish and Wildlife Service (Goodlett, 2005).

Survey Methods
Prior to the field survey, available literature and databases, including the California Natural Diversity Database (CNDDB), were reviewed to identify sensitive habitats and special status wildlife species, specifically BUOW, in the vicinity of the study area.

VCS biologists conducted four protocol BUOW surveys. Table 1 provides the survey dates and environmental conditions for each of the surveys conducted within the study area.

The surveys were not conducted during rain, high winds (>12 miles per hour (mph) (20 kilometers) that impeded detection of BUOW or sign, dense fog, cloud cover >75%, or temperatures above 90°F (32°C).

The BUOW surveys consisted of four surveys in accordance with the Staff Report guidelines, with the last three surveys being generally three weeks apart. The surveys involved walking through suitable habitat within the study area. The pedestrian survey transects were spaced at an appropriate distance to allow 100 percent visual coverage of the ground surface, adjusting for vegetation height and density. Parcels of land that could not be accessed (e.g., private property) were viewed using binoculars from suitable vantage points to survey for BUOW activity or signs thereof. The only inaccessible lands were within the 500-foot surrounding survey buffer.

During the surveys, VCS paid special attention to those habitat areas that appeared to provide suitable habitat for BUOW. The methods used to detect and identify BUOW included direct sighting of BUOW and observation of key signs such as scat, tracks, burrows, nests, and calls. All encountered burrows or structure entrances were checked for the presence of BUOWs, molted feathers, cast pellets, prey remains, eggshell fragments, tracks, or excrement at or near a burrow entrance. Natural or man‐made structures and debris piles that could support BUOWs were also surveyed. All burrows were monitored at a short distance from the entrance, and at a location that would not interfere with owl behavior.

Onsite soil conditions, topography, vegetative communities, and habitat quality were documented during the field surveys. All wildlife species encountered visually or audibly during the field survey were identified and recorded in field notes. Binoculars were used to aid in the identification of observed wildlife. Photographs were taken to document existing conditions within the study area; photopages are attached (Exhibit A).

Results - Existing Conditions
The Project Footprint is surrounded by agricultural lands such as dairies, stockyards, row crops, and nurseries to the north. A few trees in the southern portion of the site could potentially provide habitat for raptors. Portions of the site are not suitable for BUOW due to active plant nursery operations. As shown on Figure 3, the northern and westerns portions are no longer used for nursery operations and contain suitable habitat and burrows. Suitable habitat was also found within western buffer area. The buffer area to the north is predominantly developed with residential uses, the buffer area to the south is under construction, and the buffer area to the east is comprised of active dairy farms. As shown on Figure 4 (Vegetation Map) the Project 1614

the survey within the study area: California ground squirrels (Otospermophilus beecheyi) and Audubon’s cottontail (Sylvilagus audubonii).

Results - BUOW
During the four BUOW surveys, no BUOW or evidence of BUOW was observed within the study area. Potentially suitable burrows were found within the study area (Figure 3); however, the burrows did not display any sign of BUOW use around the burrow entrances. Potential BUOW foraging and nesting habitat was observed within the study area and in the vicinity. Due to the lack of presence of BUOW and lack of occupied burrows the study area is considered not to be occupied by BUOW.

Conclusion
Based on the results of the burrowing owl focused surveys, no burrowing owls or evidence of BUOW activity (e.g., active burrows, whitewash, pellets, etc.) were detected during the surveys.

As a result, the Study Area was not considered to be occupied by BUOW. Because the Study Area contains burrows suitable for burrowing owl and suitable burrowing owl foraging habitat, surveying for BUOW, which is also a raptor, will be addressed through the 30-day preconstruction clearance survey (MM B-4) prior to any ground disturbing activities to avoid direct take of burrowing owls in compliance with the CDFW protocol.

The results of the latest Delhi Sands Flower-loving Fly focused survey (2022) concluded that:

Since suitable Delhi series soils were not found, the site does not meet the baseline criterion to be considered for focused surveys as per the USFWS protocol (1996) and does not appear suitable for DSFLF occupation.

Additionally, no other sensitive resources were incidentally observed by the surveyors. For example, no hydrological features that could be viewed as a jurisdictional water of the United States or State of California were observed. Vegetation was sparse, and land cover was dominated by disturbed / developed areas and ruderal vegetation communities, therefore, no sensitive plant communities were observed. The prior DSF surveys concluded that the DSF did not occupy the site due to a lack of suitable habitat. The biological measures from the 2006 West Haven Specific Plan EIR are excerpted below:

B-2 Prior to issuance of grading permit(s), a habitat land acquisition fee of $4,320 per acre shall be paid by Project applicant(s); and placed into a trust account for use upon Project development and construction activities, for the restoration and rehabilitation of the WRCA agreed to be provided at the 145-acres within the El Prado/Chino Basin. The fee shall be paid in accordance with the September 10, 2002 modification to NMC GPA Policy 18.1.12 and Implementation Measure I-6, that states a 145-acre WRCA shall be provided through either a mitigation land bank, or by purchasing a property through development mitigation/impact fees.

Agency: City Planning Department, The Endangered Habitat’s League and the Sierra Club Timing: Prior to issuance of Grading Permits for the Project B-3 Prior to clearing the Project site of vegetation during nesting season, a qualified biologist shall conduct a site survey and mark (to protect) all active nests.

Additionally, to avoid nesting bird impacts, the Project site shall not be cleared between March 1 and September 15. Prior to clearing any vegetation from around active nests, or the clearing of any nests, a USFS Permit to Reduce Nesting Birds if Present, from the USFWS shall be secured. Not clearing/grubbing the site between March and September reduces the possibility of a disturbance to or take of nesting birds, their young, or causing the adults to abandon their nests. This increases the potential for successful breeding and propagation of the species.

Agency: City Building Department and the USFWS
Timing: Prior to Project clearing and/or construction activities B-4 Thirty days prior to any Project construction, an ornithologist shall survey for raptor nests according to CDFG requirements. If active nests are detected, the nests shall be flagged and all Project construction activities shall be kept 300 feet of nesting raptors and 500 feet of nesting migratory birds, until the young birds have safely fledged, as determined by the ornithologist. Active raptor nests shall be avoided per CDFG requirements. The 300 and/or 500 foot exclusion buffers between construction and nesting birds reduces the chances of accidental take or nest abandonment due to construction activities and noise. This increases the potential for successful breeding and the propagation of the species.

Re: Habitat suitability evaluation for Delhi Sands Flower-loving Fly for two properties within the West Haven Specific Plan in Ontario, California
Executive Summary
Guy Bruyea, a biologist permitted by the U.S. Fish and Wildlife Service (Section 10 (a) (1) (A) permit number TE-837439-8 expiring 6/24/2024) to survey for the federally endangered Delhi Sands Flower-loving Fly (DSFLF; Rhaphiomidas terminatus abdominalis), conducted a habitat suitability evaluation on October 3, 2022 at two sites within the West Haven Specific Plan, a northern site consisting of PA 1 and PA 2 totaling 46.5 acres and a northern site consisting of PA 5 and PA 7 totaling 46.3. acres. It was concluded that both sites are highly unsuitable for DSFLF occupation and, more importantly DSFLF reproduction, based on long-term historical land use and current site conditions.

Purpose of Study
The Delhi Sands Flower-loving Fly was listed as an endangered species by the U.S. Fish and Wildlife Service (Service) on September 23, 1993 (58 Federal Register 49881) and is protected under the provisions of the Endangered Species Act of 1973, as amended (ESA). The ESA prohibits anyone from “taking” a listed species. Take includes, but is not limited to, harming, harassing, or killing individuals of a listed species as well as destruction of habitat occupied by listed species.

DSFLF habitat is limited to areas that include Delhi series soils, an aeolian (wind-deposited) soil type. The Service has identified the presence of Delhi series soils as the baseline criterion for the determination of suitable or potentially suitable habitat for this species (USFWS, 1996). Fine unconsolidated soil is required for oviposition (egg laying) as females must insert their abdomens 1629
 Page 2
deep into the sand during this process (Rogers and Mattoni, 1993). The larval portion of the DSFLF’s life cycle is largely unknown. Larval development apparently takes place in the sand and is presumed to take either one or two years.

The project proponent proposes to develop the properties (Figure 1). This habitat suitability evaluation is focused on determining the suitability of the site for DSFLF habitation.

Site Description
PA 1 (Assessor Parcel Number (APN) 0218-151-48) and PA 3 (APN 0218-151-10) lie adjacent to one another and are a combined 46.5-acres located within the City of Ontario, California (Figure 1, Photograph 1). The site is situated near two high traffic roads, with Riverside Boulevard along its northern boundary and Haven Avenue along its eastern boundary. A high-density residential subdivision (associated with East Sweetbay Way) is located along its southern site boundary. A chain-link fence with privacy tarping is present on the southern portion of the PA 1 and PA 3 site, and various other types of fencing are present for the remainder of the site. Site access was from an active landscape nursery located at the southwest corner of Riverside Boulevard and Haven Avenue, and two locked gates situated along Haven Avenue to the south. Landscape nursery operations appear to have been significantly reduced in the last two years (based on historical Google Earth imagery). Active landscape nursery operations are now only present on a 10-acre adjacent parcel to the northeast of the PA 1 and PA 3 site.

The 46.3-acres combined PA 5 and PA-7 site includes three APNs: 0218-151-37, 0218-151-39, and 0218-151-40. The center of the PA 5 and PA 7 site is located approximately 0.5 mile south of the PA 1 and PA 3 site (Figure 1, Photograph 2). It is also situated near two high traffic roads, with Chino Avenue along its northern boundary and Haven Avenue along its eastern boundary. A chainlink fence with privacy tarping is currently present along the eastern and northern portions of the PA 5 and PA 7 site. Other plastic privacy fencing is present along its southern boundary, and no fencing is present along its western boundary. A residential subdivision (Aspen Street) is located near its southern boundary. Site access by vehicle was from an open gate along Haven Avenue utilized by site workers. Additional access (on foot) was achieved at the southwest site corner where Klassen Street and Oakville Avenue intersect.

The PA 1 and PA 3 site is mostly flat with a slight decrease in elevation towards its southwest corner, and lies at an elevation of 795 feet (northeast corner) to 771 feet (southwest corner) above mean sea level (AMSL). The PA 5 and PA 7 site is mostly flat with a slight decrease in elevation towards its southwest corner, and lies at an elevation of 763 feet (northeast corner) to 749 feet (southwest corner) AMSL.

In general, mostly residential subdivisions surround both sites to the north, west and south. A mixture of disturbed open space, sites undergoing development, and various commercial and industrial areas lie to the east. These surrounding developments have likely disrupted natural aeolian processes for an extended period of time, which is in part evidenced by the presence of compacted soils and the absence of high quality Delhi series soils and dunes inhabited with native vegetation.

Although unconsolidated soils are present on some areas of the PA 1 and PA 3 site, much of the site contains a gravely surface layer associated with ongoing and past nursery operations.

Historically, possibly going back decades, the site was likely used for dairy farming and various 1630
 Page 3
agricultural operations as well. Although much of the site consists of compacted soils, some areas are subject to off-road vehicle use and regular disking, which exposes some of the softer unconsolidated soils underneath. However, these exposed soils are heavily infiltrated with organic matter based on their coloration, which was tan to brown. Soils are not white or off white like undisturbed Delhi series soils observed on DSFLF occupied sites.

Away from current nursery operations northeast of PA 1 and PA 3, evidence of past landscape nursery use is present throughout the PA 1 and PA 3 site, especially in its southern area. Various ornamental non-native trees and shrubs have become established there. One large area contains a surface layer made up of mulch. Various pipes, irrigation lines, plastic pots and other debris associated with past nursery operations are also present. Very few native plants were observed on the PA 1 and PA 3 site during the survey. In addition to ornamental species associated with past nursery operations, conspicuous weedy species found in abundance include (but are not limited to) golden crownbeard (Verbesina encelioides), small horseweed (Erigeron bonariensis), pricklylettuce (Lactuca serriola), fireweed (Kochia scoparia), Russian thistle (Salsola tragus), tumble pigweed (Amaranthus albus), lamb's quarters (Chenopodium album), London rocket (Sisymbrium irio), and puncture vine (Tribulus terrestris).

At the time of the PA 5 and PA 7 survey, several dump trucks (4-5), skip-loaders (4-5), a water truck (1) and workers were actively working on the site. For safety reasons, only the perimeter of the site and other areas not actively subject to dump truck and skip-loader traffic was surveyed on foot. Imported soils (appeared to be a mixture of manure and dirt) were being moved/dumped throughout the site. Several large dirt/manure piles were present on the southeastern quadrant of the site. The site appeared to have been graded recently given its near total lack of vegetation. No native or non-native plants were observed on most of the site (a few plants were present along southern and southwestern boundaries). Historically, the PA 5 and PA 7site was likely used for dairy farming and various agricultural operations. Although much of the site contains unconsolidated soils, soils are heavily infiltrated with organic matter based on their coloration, which was tan to dark brown. Odor associated with manure was also detected.

Methods
The site was surveyed on October 3, 2022 by Guy Bruyea (TE-837439-8). Meandering transects were walked throughout the site to document vegetation, physiographic features, vertebrate and invertebrate species, and to search for the occurrence of Delhi series soils. Access was more limited at the PA 5 and PA 7 site where equipment operations were underway but parts of the interior and the perimeter were reviewed. Photographs were taken of representative features at the site.

The survey was conducted under hazy skies with temperatures ranging from 72 to 81 °F. Winds were light.

Results
Although Delhi series soils are historically mapped for the site and surrounding areas, anthropogenic disturbances over decades have altered the natural topography, aeolian processes, vegetation (mostly non-native weeds on PA 1 and PA 3 and virtually no plants on PA 5 and PA 7) and soil characteristics of both sites such that the sites do not now meet the USFWS baseline requirement for conducting focused surveys, the presence of Delhi series soils. Further, surrounding areas are highly disturbed and/or developed as well, so the likelihood of a dispersing 1631
 Page 4
DSFLF utilizing the site for foraging or reproduction would be very low. In addition, because nearly all areas of the site contain either a gravelly, compacted, or contaminated surface layer, the site would not be conducive to successful oviposition by dispersing DSFLF females.

Little or no fossorial insect or small mammal activity was observed on either site. In berm areas along some site edges (especially the western perimeter), holes associated with California ground squirrels were observed. These holes could be utilized by burrowing owls, but no burrowing owl or sign (scat, feathers, rodent bones, etc.) indicating recent activity was observed.

Twelve bird species were observed on the PA 1 and PA 3 site during the survey: Turkey vulture, common raven, house finch, mourning dove, rock dove (pigeon), white-crowned sparrow, northern mockingbird, western kingbird, Say's phoebe, American kestrel, American crow, and red-tail hawk (fly over). California ground squirrel was observed on the PA 1 and PA 3 site. Insect activity was poor on the PA 1 and PA 3 site.

Five bird species were observed on the PA 5 and PA 7 site during the survey: Turkey vulture, common raven, house finch, mourning dove, and rock dove (pigeon). Most birds were observed flying over the PA 5 and PA 7 site or perched on site fencing. California ground squirrel holes were observed at the southwest corner of the PA 5 and PA 7 site, but no California ground squirrels were observed at that location. No insect activity was observed on the PA 5 and PA 7 site.

Plants that are often found on DSFLF-occupied sites, including California buckwheat (Eriogonum. fasciculatum), California croton (Croton californicus) telegraph weed (Heterotheca grandiflora), and annual bursage (Ambrosia acanthicarpa) were not observed during this assessment.

Conclusion
Since suitable Delhi series soils were not found, the site does not meet the baseline criterion to be considered for focused surveys as per the USFWS protocol (1996) and does not appear suitable for DSFLF occupation.

WEST HAVEN SPECIFIC PLAN AMENDMENT VEHICLE MILES TRAVELED (VMT)

ANALYSIS
Mr. Sage McCleve and Mr. Derek Barbour,
Urban Crossroads, Inc. is pleased to provide the following Vehicle Miles Traveled (VMT) Analysis for the West Haven Specific Plan Amendment (Proposed Specific Plan). The West Haven Specific Plan is bounded by Riverside Drive to the north, Turner Avenue to the west, Schaefer Avenue to the south, and Haven Avenue to the east the City of Ontario.

PROJECT OVERVIEW
The currently approved West Haven Specific Plan (Approved Specific Plan) allows the following land uses and development intensities:
• 753 Total Dwelling units
o 488 Detached Dwelling Units
o 265 Attached Dwelling Units
• 87,000 square feet of Retail Uses
• 9.8-acre Elementary School Site
The Project would designate Planning Areas 1 (PA-1) and 3 (PA-3) with medium density residential and low-medium density residential land use designations, respectively, consistent with The Ontario Plan (TOP) 2050 Policy Plan (See Attachment A). The allowed uses in PA-1 would change from Detached Courtyard and 4,000 square foot (sf) lots to Detached Courtyard and Attached Homes, and the allowed uses in PA-3 would change from 4,950 square foot lots to Detached and Attached Homes. This would permit Planning Area 1 to increase from 173 dwelling units to 451 dwelling units and Planning Area 3 to increase from 92 dwelling units to 203 dwelling units, which represents an increase of 389 dwelling units compared to the currently allowed 265 units in these PAs. In total, the permitted units would equate 1,142 dwelling units, details of these changes can be found in Table 1.

TABLE 1: PROPOSED AND APPROVED SPECIFIC PLAN LAND USE SUMMARY

BACKGROUND
Changes to California Environmental Quality Act (CEQA) Guidelines were adopted in December 2018, which require all lead agencies to adopt VMT as a replacement for automobile delay-based level of service (LOS) as the measure for identifying transportation impacts for land use projects.

This statewide mandate went into effect July 1, 2020. To aid in this transition, the Governor’s Office of Planning and Research (OPR) released a Technical Advisory on Evaluating Transportation Impacts in CEQA (December of 2018) (Technical Advisory) (1). Based on the Technical Advisory, the City of Ontario has developed and adopted their own VMT methodologies and thresholds (Resolution No. 2020-071), which were adopted by City Council in June 2020 (City Guidelines) (2).

This VMT analysis has been developed based on the adopted City Guidelines.

VMT ANALYSIS

ANALYSIS APPROACH
As noted previously, the Proposed Specific Plan is an amendment to an approved Specific Plan.

Therefore, this VMT analysis compares the VMT generated by the Proposed Specific Plan to the Approved Specific Plan.

14574-04 VMT

VMT MODELING
The City Guidelines identifies San Bernardino Traffic Analysis Model (SBTAM) as the appropriate tool for conducting VMT analysis for land use projects in the City of Ontario, as it considers interaction between different land uses based on socio-economic data, such as population, households, and employment. The calculation of VMT for land use projects is based on the total number of trips generated and the average trip length of each vehicle. The City of Ontario has recently updated travel demand model also known as The Ontario Plan (TOP 2050) model, which is a modified version of SBTAM. Urban Crossroads has obtained the TOP 2050 model from the City of Ontario. The TOP 2050 model is also consistent with the model used to develop the City’s VMT impact thresholds described by the City Guidelines. Therefore, the vehicle trips and average daily trip length for the currently Approved Specific Plan and Proposed Specific Plan are model derived from the TOP 2050 model.

PROJECT LAND USE CONVERSION
In order to evaluate VMT, standard land use information must first be converted into a SBTAM compatible dataset. The SBTAM model utilizes socio-economic data (SED) (e.g., population, households, employment, etc.) instead of land use information for the purposes of vehicle trip estimation. Project land use information such as dwelling units and building square footage must first be converted to SED for input into SBTAM. Adjustments in SED have been made to the appropriate Project TAZ within the SBTAM model to reflect the Project’s proposed land use changes. Table 2 summarizes the SED inputs used to reflect the proposed Project.

TABLE 2: POPULATION & EMPLOYMENT ESTIMATES
Approved Specific Plan Proposed Specific Plan
Households 753 1,142
Population 2,643 4,008
Employment 253 253
Service Population 2,896 4,261

MODELING METHODOLOGIES
Origin/Destination VMT Method
Consistent with City Guidelines, project level VMT analysis should evaluate total VMT divided by a project’s service population (i.e., population and employment). Total VMT is calculated from SBTAM’s Origin/Destination (OD) trip matrices and then divided by a project’s service population to derive the VMT efficiency metric VMT per service population (SP) (i.e., population and employment). The OD method for calculating VMT sums all weekday VMT generated by trips with at least one trip end in the study area (i.e., Project TAZ or City Boundary). The OD method accounts for all trips (i.e., both passenger cars and trucks) and trip purposes (i.e., total VMT) and therefore provides a more complete estimate of VMT.

Boundary VMT Method
1638

14574-04 VMT
City Guidelines also acknowledge that a VMT analysis should also contain an evaluation of a project’s effect on VMT, which can be performed using the boundary method of calculating VMT.

The boundary method is the sum of all weekday VMT on the roadway network within a designated boundary (i.e., City boundary or other designated geographic area). The boundary method estimates VMT by multiplying vehicle trips on each roadway segment within the boundary by that segment’s length. This approach consists of all trips, including those trips that do not begin or end in the designated boundary. Consistent with City Guidelines, the City of Ontario was used as the boundary for this assessment. In addition, as the Project is located near the southern portion of the City of Ontario, an additional assessment of a ten-mile boundary area surrounding the Project site has also been conducted to ensure trips associated with the Project are not omitted.

VMT COMPARISONS AND FINDINGS
Table 3 presents the VMT calculated for both the currently Approved Specific Plan and the Proposed Specific Plan.

TABLE 3: VMT COMPARISON
Approved Specific Plan Proposed Specific Plan
Population 2,643 4,008
Employment 253 253
Service Population 2,896 4,261
Total OD VMT 93,811 123,631
OD VMT/SP 32.39 29.01
City Boundary VMT 9,602,250 9,600,169
City Boundary VMT/SP 13.59 13.56
10-Mile Boundary VMT 35,736,771 35,735,624
10-Mile Boundary VMT/SP 22.34 22.32
Origin/Destination VMT Findings
The Proposed Specific Plan includes 389 additional dwelling units as compared to the Approved Specific Plan, which results in additional trips and consequently an increase in Total OD VMT.

However, Total OD VMT divided by the Project’s SP results in a lower OD VMT/SP for the Proposed Specific Plan as compared to the Approved Specific Plan, which indicates a more efficient land use plan when incorporated with the complementary land uses in the surrounding area as compared to the Approved Specific Plan.

Boundary Method VMT Findings
Boundary VMT is higher under the Proposed Specific Plan conditions in both the City of Ontario boundary and 10-mile radii boundary of the Project location, but similarly to the OD VMT/SP results, the Boundary VMT/SP is lower under the Proposed Specific Plan, which also indicates a more efficient land use plan when incorporated with the complementary land uses in the surrounding area as compared to the Approved Specific Plan. 1639

SUMMARY
The Proposed Specific Plan would increase residential density by 389 dwelling units as compared to the Approved Specific Plan and result in a reduction in VMT per SP as compared to the Approved Specific Plan. As noted in the Handbook for Analyzing Greenhouse Gas Emission Reductions, Assessing Climate Vulnerabilities, and Advancing Health and Equity (CAPCOA, 2021) (3) (2021 Handbook) “Increasing residential densities affect the distance people travel and provide greater options for the mode of travel they choose. Increasing residential density results in shorter and fewer trips by single-occupancy vehicles and thus a reduction in GHG emissions.”1 This analysis indicates that the Proposed Specific Plan is more efficient from a VMT perspective as compared to the Approved Specific Plan and results in a less than significant impact.

Water Supply Assessment for West Haven Specific Plan Amendment Introduction 1 SB 610 WATER SUPPLY ASSESSMENT
SECTION 1 - INTRODUCTION
Senate Bill 610 (SB 610) was signed into California state law with an effective date of January 1, 2002. SB 610 amended existing legal requirements for confirmation of water supply sufficiency as a condition of approval for development projects. The confirmation of water supply sufficiency is achieved through an assessment of the water supplier's existing and future water sources, and existing and projected water demand in relation to a "project" as defined by California Water Code (CWC) section 10912, resulting in the production of a project-specific Water Supply Assessment (“WSA” or “Assessment”). Additional analysis is required in the WSA if any portion of the water supply includes groundwater. The WSA is prepared and adopted by the water supplier and included in the California Environmental Quality Act (CEQA) analysis for the project. The CEQA Lead Agency must then independently determine, based on the entire record, whether water supplies will be sufficient to satisfy the demands of the project, in addition to existing and planned future uses (CWC section 10911). The WSA is not a commitment to serve the proposed project.

Law
CWC section 10910:
(a) Any city or county that determines that a project, as defined in Section 10912, is subject to the California Environmental Quality Act (Division 13 (commencing with Section 21000) of the Public Resources Code) under Section 21080 of the Public Resources Code shall comply with this part.

CWC section 10912:

For the purpose of this part, the following terms have the following meanings:
(a) "Project” means any of the following:
1650
Ontario Municipal Utilities Company Section 1
Water Supply Assessment for West Haven Specific Plan Amendment Introduction 2 (1) A proposed residential development of more than 500 dwelling units. (2) A proposed shopping center or business establishment employing more than 1,000 persons or having more than 500,000 square feet of floor space. (3) A proposed commercial office building employing more than 1,000 persons or having more than 250,000 square feet of floor space. (4) A proposed hotel or motel, or both, having more than 500 rooms. (5) A proposed industrial, manufacturing, or processing plant, or industrial park planned to house more than 1,000 persons, occupying more than 40 acres of land, or having more than 650,000 square feet of floor area. (6) A mixed-use project that includes one or more of the projects specified in this subdivision.
(7) A project that would demand an amount of water equivalent to, or greater than, the amount of water required by a 500-dwelling unit project.

1.1 Purpose
The Ontario Municipal Utilities Company (OMUC) is a department of the City of Ontario (City) and the water supplier to the City. OMUC commissioned this Assessment from Albert A. Webb Associates (WEBB) on March 28, 2022, to answer the following key question pursuant to SB 610: whether the projected supply for the next 20 years, based on normal, single dry and multiple dry years, will meet the demand projected for the project plus existing and planned future uses, including agricultural and manufacturing uses.

1.2 Background
The West Haven Specific Plan was adopted by Ontario City Council on July 17, 2007.

The West Haven Specific Plan is located in the City of Ontario’s 8,200-acre Ontario 1651
Ontario Municipal Utilities Company Section 1
Water Supply Assessment for West Haven Specific Plan Amendment Introduction 3 Ranch (formerly, New Model Colony (NMC)), and located south of the 60 Freeway, east of Turner Avenue, west of Haven Avenue between Riverside Drive to the north and Old Schaefer to the south (see Figure 1 - Regional Map and Figure 2 – Aerial View). The approved 2007 West Haven Specific Plan allowed up to 753 dwelling units on 146.9 acres, Neighborhood Center on 11.7 gross acres, an elementary school site on approximately 10 net acres, a five net acre Neighborhood Park and approximately 10 acres of paseos and pocket parks of former dairy and agricultural lands (SPA, p. 1-3).

On June 15, 2021, the City adopted its 2020 Urban Water Management Plan (UWMP) by Resolution No. 2021-059, a copy of which is located in Appendix A.1 The City
recently prepared updates to its Water Master Plan and Recycled Water Master Plan in June 2020, which include the current unit water demand factors for potable and recycled water as well as ultimate buildout water demand projections (AKM and Stantec, respectively) .The projected water demands of the 2020 UWMP are based on the City’s 2020 master plan updates (pertinent excerpts of the master plans are located in Appendix E and K of the 2020 UWMP). The Specific Plan Land Use Plan that was used in the master plan updates and 2020 UWMP is shown in Figure 3 – Land Use Plan Used for 2020 UWMP Projections. Copies of the master plans are located in Appendix B and Appendix C.
1 The City Council also passed on June 15, 2021, Resolution No. 2021-061 to amend the 2015 UWMP to reflect consistency with the Delta Plan, and Resolution No. 2021-060 to adopt the 2020 Water Shortage Contingency Plan. 1652

Water Supply Assessment for West Haven Specific Plan Amendment Introduction 7 1.3 Proposed Project
The City is preparing an amendment to the West Haven Specific Plan to increase the maximum allowable number of dwelling units and densities in two residential Planning Areas (PA): PA 1 and PA 3 (“West Haven Specific Plan Amendment, or “Project’). The Project would increase the number of allowable units by 278 units in PA 1 and the corresponding net density would increase from 6.78 du/acre to 17.68 du/acre (see Figure 4 – Proposed Land Use Plan). The total number of allowable units would increase by 111 units in PA 3 and the corresponding net density would increase from

4.86 du/acre to 10.72 du/acre. With these changes, the total number of allowable units in the West Haven Specific Plan would increase from 753 units to 1,142 units (SPA, p. 3-3). For CEQA compliance, the City is preparing an addendum to the City General Plan Environmental Impact Report (EIR); therefore, this Project is considered to be “subject to CEQA” pursuant to CWC section 10910. The Project is considered a “project” under SB 610 pursuant to the following CWC section 10912 definition:
(1) A proposed residential development of more than 500 dwelling units.

As shown in Figure 4, PA 4, PA6, PA 8, and PA 9 have been developed. The Project does not propose any changes to PA 2, PA 5, or PA 7, nor changes to “Other Uses” (i.e., Master Planned Roadways, Neighborhood Edge Buffers SCE & SCG Easements, SCE Fee Owned Parcel, Old Schaefer Road R/W (to be abandoned)). 1656

Water Supply Assessment for West Haven Specific Plan Amendment Introduction 9 The Project will have potable and recycled water provided by OMUC. City Ordinance No. 2689 requires all new development to connect to, and use recycled water for all approved uses, including but not limited to landscape irrigation (codified in City Municipal Code Sections 6-8.7 to 6-8.279). As stated in the proposed Specific Plan Amendment, “The West Haven Specific Plan shall comply with City Ordinance 2689 and make use of recycled water for all approved uses, including but not limited to irrigation of parks, schools, street landscaping, recreational trails, HOA maintained onsite common areas, and commercial/ industrial landscaping” (SPA, p. 5-8). In the event recycled water supply is inadequate, potable water will be used in the recycled water system until recycled water service can resume (ibid).

1.4 Prior Water Supply Assessment
A WSA and Written Verification of Sufficient Water Supply (WV) dated October 27, 2004, were prepared for the 8,200-acre Ontario Ranch by WEBB on behalf of the City.

The 2004 WSA/WV was used for demonstrating water supply sufficiency for the original 2007 West Haven Specific Plan (URS, p. 3-129). Because the Project increases the expected water demand from prior assumptions for two planning areas and proposes some different land uses not previously included in the land use plan, and the City has updated its water use and water supply information since 2004, a new WSA is prepared herein consistent with CWC section 10910(3). This WSA addresses the additional units proposed for PA-1 and PA-3. Per request of OMUC, additional calculations that address the other PA’s are included herein.

Law
CWC Section 10910:
(h) Notwithstanding any other provision of this part, if a project has been the subject of a water supply assessment that complies with the requirements of this part, no additional water supply assessment shall be required for subsequent projects that were part of a larger project for which a water supply assessment was completed 1658
Ontario Municipal Utilities Company Section 1
Water Supply Assessment for West Haven Specific Plan Amendment Introduction 10 and that has complied with the requirements of this part and for which the public water system, or the city or county if either is required to comply with this part pursuant to subdivision (b), has concluded that its water supplies are sufficient to meet the projected water demand associated with the proposed project, in addition to the existing and planned future uses, including, but not limited to, agricultural and industrial uses, unless one or more of the following changes occurs:
(1) Changes in the project that result in a substantial increase in water demand for the project.
(2) Changes in the circumstances or conditions substantially affecting the ability of the public water system, or the city or county if either is required to comply with this part pursuant to subdivision (b), to provide a sufficient supply of water for the project.
(3) Significant new information becomes available which was not known and could not have been known at the time when the assessment was prepared.

1.5 Project Relation to the Urban Water Management Plan The City of Ontario/OMUC is the water supplier for the Project and has adopted a 2020 UWMP, a copy of which is provided in Appendix A. This WSA will rely on the 2020 UWMP and updated information from OMUC for 2021 data has been added where possible. The assumptions on ultimate (buildout) water demand in the 2020 UWMP for Ontario Ranch were derived from land use-based water demand factors according to the City’s 2020 Water Master Plan (AKM). Specifically, all approved Specific Plans and other current planning information were utilized in the 2020 Water Master Plan for the Ontario Ranch area, which includes the West Haven Specific Plan (AKM, p. 4-12). The land use designations that are assumed in the 2020 UWMP water demand projections are based on the approved West Haven Specific Plan land use plan (Figure 3). 1659
Ontario Municipal Utilities Company Section 1
Water Supply Assessment for West Haven Specific Plan Amendment Introduction 11 As stated in the 2020 Water Master Plan, “For future developments, water unit demand factors were used to estimate future water use. Potable water unit demand factors are generally based on the factors that were developed as a part of a study completed in May 2016 entitled “Ultimate Citywide Water Demand Estimate” (AKM, p. 4-9). Further, “The residential unit demand factors were first developed in terms of gpd/person. Then the maximum densities (people/du and du/ac) were applied to determine the factors in other units. The resulting unit factors in terms of gpd/du and gpd/ac represent the maximum expected demand factors” (ibid). Lastly, the unit water demand factors used for the 2020 UWMP, 2020 Water Master Plan, and herein use recent actual projections of residential densities that are more than those included in the TOP (General Plan) at the time the plans were written (ibid).

According to the Water Code, if a project’s water demand has been accounted for in the water supplier’s most recent UWMP, then the WSA may use the UWMP as the source of the information required in the WSA. The determination as to whether the Project’s water demand has been accounted for in the most recent UWMP is located in Section 2 – Water Demand Analysis.

Relation of Water Supplier to other Urban Water Management Plans The City is a member agency of several water suppliers: Inland Empire Utilities Agency (IEUA), Water Facilities Authority (WFA), Chino Basin Desalter Authority (CDA), and San Antonio Water Company (SAWCo). IEUA obtains water from The Metropolitan Water District of Southern California (MWD). In addition, WFA obtains MWD water through IEUA. Each of these water suppliers has adopted individual 2020 UWMPs (copies of said plans are provided in Appendix D through Appendix H). Further, each of these agencies documented coordination with the City for preparation of said UWMP’s and included the City’s projected water demands into their individual UWMPs (MWD (p. 1- 9), IEUA (p. 2-7), SAWCO (p. 4-6), WFA (p. 4-10), and CDA (p. 4-8)). 1660

CWC Section 10910:
(c) (1) The city or county, at the time it makes the determination required under Section 21080.1 of the Public Resources Code [CEQA], shall request each public water system identified pursuant to subdivision (b) to determine whether the projected water demand associated with a proposed project was included as part of the most recently adopted urban water management plan adopted pursuant to Part 2.6 (commencing with Section 10610).
(2) If the projected water demand associated with the proposed project was accounted for in the most recently adopted urban water management plan, the public water system may incorporate the requested information from the urban water management plan in preparing the elements of the assessment required to comply with subdivisions (d), (e), (f), and (g).
(3) If the projected water demand associated with the proposed project was not accounted for in the most recently adopted urban water management plan, or the public water system has no urban water management plan, the water supply assessment for the project shall include a discussion with regard to whether the public water system's total projected water supplies available during normal, single dry, and multiple dry water years during a 20-year projection will meet the projected water demand associated with the proposed project, in addition to the public water system's existing and planned future uses, including agricultural and manufacturing uses.
(4) If the city or county is required to comply with this part pursuant to subdivision (b), the water supply assessment for the project shall include a discussion with regard to whether the total projected water supplies, determined to be available by the city or county for the project during normal, single dry, and multiple dry water years during a 20-year projection, will meet the projected water demand associated 1661
Ontario Municipal Utilities Company Section 1
Water Supply Assessment for West Haven Specific Plan Amendment Introduction 13 with the proposed project, in addition to existing and planned future uses, including agricultural and manufacturing uses.

1.6 Statewide and Local Water Conservation Efforts
The Ontario City Council adopted Ordinance No. 3027 on September 1, 2015, in response to the statewide Emergency Conservation Regulations mandated at that time by the State Water Resources Control Board. Ordinance 3027 updated the City’s Water Conservation Plan that is codified in Chapter 8A, Title 6 of the City’s Municipal Code (“Water Conservation Plan”).

The City Council adopted its 2020 Water Shortage Contingency Plan in June 2021, which describes the methods to achieve and the implications of reducing water supplies to at least 50 percent (the plan is located in Chapter 8 of the 2020 UWMP).

The City and OMUC implement various programs to reduce customer water consumption, including stringent use restrictions, actions, and penalties, as well as public outreach, education, and communication programs. As of April 2022, the City is in Stage 2 of the Water Conservation Plan. Stage 2 addresses a water supply shortage of up to 20 percent (WSCP, p. 8-7) and includes the restrictions activated in Stage 1, which are shown below.

Excerpt from 2020 City of Ontario Water Shortage Contingency Plan, p. 8-7. 1662
Ontario Municipal Utilities Company Section 1
Water Supply Assessment for West Haven Specific Plan Amendment Introduction 14 With the signing of Assembly Bill (AB) 1668 and SB 606, the state has set an Indoor Residential Standard of 55 gallons per capita per day (GPCD) beginning January 1, 2025, which will decrease to 50 GPCD beginning January 1, 2030 (CWC section 10609.4(a)). The per person unit water use factors used by the City in the 2020 UWMP for water demand planning purposes are based on a minimum of 60 gpd/person for high density residential with recycled water, up to 172 gpd/person for rural residential (UWMP, p. 4-10). In regard to landscaping guidelines for the Project, “All landscaping shall meet the City of Ontario Development Standards, Codes and Regulations, unless otherwise specified within the West Haven Specific Plan document.” (SPA, p. 8-35).

1.7 Methodology of Analysis
This Assessment follows the DWR Guidebook for Implementation of Senate Bill 610 and Senate Bill 221 of 2001 (DWR 2003). CWC citations contained herein are current as of January 1, 2022. Section 1 of this Assessment describes the existing and proposed land use designations of the Project site, the proposed Project’s relation to a previous WSA and the water supplier’s most recent UWMP. Section 2 provides the water demand analysis of the Project; Section 3 reviews the projected water supplies for the Project; Section 4 contains the required discussion of the water supplier’s groundwater supplies; and Section 5 concludes the Assessment by answering the primary question at hand.

Water Supply Assessment for West Haven Specific Plan Amendment Water Demand Analysis 15 SECTION 2 - WATER DEMAND ANALYSIS
The purpose of this section is to evaluate whether the proposed Project was considered in the water supplier’s planning for water demand. This section will: 1) identify the various water use sectors, 2) identify water demand by those sectors for the next twenty years, and 3) compare the calculated water demand of the proposed Project to the water demand assumed in the most recent UWMP for the same property.

Law
CWC Section 10910:
(c)(2) If the projected water demand associated with the proposed project was accounted for in the most recently adopted urban water management plan, the public water system may incorporate the requested information from the urban water management plan in preparing the elements of the assessment required to comply with subdivisions (d), (e), (f), and (g).
(3) If the projected water demand associated with the proposed project was not accounted for in the most recently adopted urban water management plan, or the public water system has no urban water management plan, the water supply assessment for the project shall include a discussion with regard to whether the public water system's total projected water supplies available during normal, single dry, and multiple dry water years during a 20-year projection will meet the projected water demand associated with the proposed project, in addition to the public water system's existing and planned future uses, including agricultural and manufacturing uses.

2.1 Citywide Demographic Factors
A variety of demographic factors may affect water use. The UWMP Act lists several demographic factors to be detailed in UWMP’s including climate, current and projected 1664
Ontario Municipal Utilities Company Section 2
Water Supply Assessment for West Haven Specific Plan Amendment Water Demand Analysis 16 population, density, and the mix of customer types (CWC sections 10631(e)(1)-(2)). As suggested by DWR, these data are provided herein and are taken generally from City’s 2020 UWMP (Appendix A).

Climate
The climate of the City including the Project site can be described as generally mild temperatures and virtually no days below freezing. Summers are dry with average maximum daily temperatures in the high 80s to low 90s. The average annual rainfall is roughly 10.68 inches. (UWMP, p. 3-5)
Population
The City is divided into two distinct areas: Old Model Colony (OMC) and Ontario Ranch, which is where the Project is located. The OMC mostly consists of residential, commercial, and industrial developments including the Ontario Airport. Ontario Ranch is currently in the process of a planned conversion from agriculture to residential, commercial, industrial, and public uses.

The OMUC water service area population as of 2020, including both OMC and Ontario Ranch, is estimated at 178,409 persons (UWMP, p. 3-6). Based on the City General Plan (“TOP”) and anticipated development patterns, population at citywide buildout in 2040 is estimated at 362,903 persons as shown in Table 2-1, which is an increase of more than 103 percent over 20 years. Most of the anticipated growth will occur through infill, densification in the OMC, and development in Ontario Ranch.

Water Supply Assessment for West Haven Specific Plan Amendment Water Demand Analysis 17 The City has considered certain demographic factors in its water management planning, including special housing needs (e.g., low-income earners, single-parent families, large families, seniors, people with disabilities, and homeless persons) (UWMP, p. 3-7).

2.2 City of Ontario’s Current and Future Water Demand
OMUC serves at least 36,514 customer connections as part of its potable and nonpotable water distribution systems (UWMP, p. 2-4). OMUC reports on a fiscal year (FY) basis (July 1, 2020 through June 30, 2021) unless required to do otherwise. In FY 20/21, the total potable water demand in the OMUC service area was 33,968 acre-feet (AF) and the recycled water demand was 8,556.74 AF (OMUC(b)). The recorded water demands by customer type for the OMUC water service area are provided in Table 2-2 (next page).

Water use patterns change during dry years. The expected changes to water demand and water supply during dry years are provided in Section 3 – Water Supply Analysis.

The City’s 2020 UWMP and 2020 Water Master Plan assume the same trend in future land use changes within the City. Namely, the City land uses are currently a nearlyequal balance of residential, commercial / industrial, and agricultural as shown in Figure 5. However, agricultural use is projected to be completely replaced with residential, commercial, and industrial by buildout (2040) as shown in Figure 6. 1668

The City’s 2020 Water Master Plan and 2020 UWMP used the approved land use plans for each Specific Plan, including West Haven, to calculate projected water demands.

Where there was no approved land use plan, the current (current as of May 2017) General Plan land use plan was used (AKM 2020). These assumptions can be found in a spreadsheet and exhibits in Appendix 4-1 of the 2020 Water Master Plan and the land use plan reproduced on Figure 3, herein. Using the City’s current unit water demand factors, the estimated potable and recycled water demands for the Project PA’s and the rest of the Specific Plan that was accounted for in the 2020 UWMP is shown in Table 2-4. Refer to Spreadsheet 1 at the end of the report for calculations.

The following assumptions were made to estimate water demand for the Project:
• Potable water demand was calculated on a per-dwelling-unit basis. • Recycled water demand was calculated on a per-gross-acre basis, to be consistent with the master plans which used gross acres for the Specific Plans. • The potable and recycled water demands of just the additional units were calculated as the difference between the proposed total number of dwelling units and the approved dwelling units. The unit water demand factors changed to match the corresponding land use designations based on maximum densities for each PA. The gross acreages did not change.
• Spreadsheet 3 calculates the potable and recycled water demands of the entire Specific Plan including the approved units and proposed additional units of the Project.
• Spreadsheet 4 calculates the potable and recycled water demands of the Specific Plan as currently approved, before the proposed Project. 1671
Ontario Municipal Utilities Company Section 2
Water Supply Assessment for West Haven Specific Plan Amendment Water Demand Analysis 23 Conclusion
The estimated total water demand for the Project site that was assumed in the 2020 UWMP is approximately 145 AFY (Table 2-4). The additional total water demand for the proposed Project’s additional units is 113 AFY (Table 2-5). Because the City’s water demand projections in the 2020 UWMP were based on a lower development density for the same piece of land than that which is proposed by the Project, it can be deduced that the water demand for the proposed Project’s additional units was not accounted for in the most recently adopted 2020 UWMP.

Ontario Municipal Utilities Company Section 3
Water Supply Assessment for West Haven Specific Plan Amendment Water Supply Analysis 24 SECTION 3 - WATER SUPPLY ANALYSIS
This section identifies the sources of potable water utilized and available to the water supplier of the proposed Project. The purpose of this section is to evaluate the water supplies that could be utilized by the proposed Project during normal, single-dry, and multiple-dry water years during a 20-year projection.

OMUC is the water supplier to the City and the proposed Project. OMUC has the following sources of water supply: City wells in the Chino Groundwater Basin; treated groundwater from the Chino Desalter Authority (CDA); recycled water from Inland Empire Utilities Agency (IEUA); purchased water from San Antonio Water Company (SAWCo); and imported wholesale water from the Water Facilities Authority (WFA).

Law
CWC Section 10910(d)(1):

The assessment required by this section shall include an identification of any existing water supply entitlements, water rights, or water service contracts relevant to the identified water supply for the proposed project, and a description of quantities of water received in prior years by the public water system, or the city or county if either is required to comply with this part pursuant to subdivision (b), under the existing water supply entitlements, water rights, or water service contracts.
(2) An identification of existing water supply entitlements, water rights, or water service contracts held by the public water system, or the city or county if either is required to comply with this part pursuant to subdivision (b), shall be demonstrated by providing information related to all of the following:
(A) Written contracts or other proof of entitlement to an identified water supply. (B) Copies of a capital outlay program for financing the delivery of a water supply that has been adopted by the public water system.
1673
Ontario Municipal Utilities Company Section 3
Water Supply Assessment for West Haven Specific Plan Amendment Water Supply Analysis 25 (C) Federal, state, and local permits for construction of necessary infrastructure associated with delivering the water supply.
(D) Any necessary regulatory approvals that are required in order to be able to convey or deliver the water supply.

3.1. Documenting Wholesale Water Supplies
Many retail water suppliers in California, including OMUC, receive supplies from one or more water wholesalers. SB 610 requires the WSA to document wholesale supplies received by: 1) describing the quantities of water received from each wholesaler in prior years; 2) identifying existing entitlements, water rights, and/or water service contracts held by the City for the wholesale supply; 3) provide proof of entitlements, water rights, service contracts, relevant capital outlay programs, and construction permits for necessary infrastructure to deliver wholesale supplies, if any; and 4) regulatory approvals required to convey or deliver the wholesale supply.

Wholesale Supplies Received
OMUC receives wholesale water from the WFA who purchases untreated imported water from IEUA, who in turn obtains it from The Metropolitan Water District of Southern California (MWD). WFA and IEUA are both wholesale water suppliers and IEUA is a member agency of MWD. MWD is a wholesaler and contractor for State Water Project water imported from northern California. State Water Project water is available as stipulated by DWR in response to the hydrology and environmental regulations that can change available supply.2 Therefore, imported water supplies to southern California can be highly variable; in January 2014 for example, the allocation of State Water Project water to all contractors was temporarily reduced to 0 percent due to persistent drought conditions. Nonetheless, MWD has projected in its 2020 UWMP, 100 percent water supply reliability over the next 20 years (2025-2045) during average, single-dry, and multiple-dry years (MWD UWMP, pp. ES-6 and ES-7). 2 DWR, State Water Project Delivery Capability Report, published every 2 years, as well as “Notice to State Water Project Contractors” issued as often as needed. 1674
Ontario Municipal Utilities Company Section 3
Water Supply Assessment for West Haven Specific Plan Amendment Water Supply Analysis 26 The amount of imported water purchased by IEUA from MWD is limited by a purchase order agreement that allows IEUA to purchase up to 93,283 acre-feet per year (AFY) at its lowest rate (Tier I) through Dec. 31, 2024 (IEUA Resolution no. 2014-12-1 located in Appendix I). The purchase order agreement includes an annual minimum purchase commitment of 39,835 AFY, which is slightly less than the minimum operational need of the region’s water treatment facilities (i.e., 40,000 AFY; WFA’s Agua de Lajos Treatment Plan (81 mgd capacity), Fontana Water Company’s Sandhill Surface Water Treatment Plant 29 mgd capacity), CVWD’s Lloyd W. Michael Water Treatment Plant (60 mgd capacity, and CVWD’s Royer-Nesbit Water Treatment Plant (11 mgd capacity)) (IEUA 2016 IWRP, p. 36). Resolution 2014-12-1 also establishes how much water WFA, Cucamonga Valley Water District, and Fontana Water Company may purchase from IEUA, up to 69,572 AFY (IEUA 2020 UWMP, p. 2-6).

The WFA was formed in 1980 as a Joint Powers Authority by the cities of Chino, Chino Hills, Ontario, Upland, and the Monte Vista Water District in order to construct and operate water treatment facilities for providing supplemental potable water to the member agencies. In 1985, the City established an agreement to purchase capacity in the WFA water treatment plant; a copy of which is located in Appendix J. Then, in 1988 the WFA finished construction of the Agua de Lejos Water Treatment Plant (WTP) in Upland to treat the imported water from IEUA and MWD to meet drinking water standards.

Currently, the Agua de Lejos WTP has the capacity to treat and disinfect 81 million gallons per day (mgd). Recorded flows through the Agua de Lejos WTP have ranged from 40 to 50 mgd during the peak summer months and can be as low as 9-12 mgd during winter months (http://www.wfajpa.org/#Facilities). As documented in WFA Ordinance No. 99-07-02 (located in Appendix K), the City owns 31.4 percent of the plant capacity of the Agua de Lejos WTP. As of 2020, that proportion is equivalent to approximately 25 mgd (28,004 AFY) (AKM 2020, p. 3-2). OMUC can purchase up to 9,915 AFY (8.9 mgd) of imported supply through WFA at Tier 1 rates. Beyond that amount, OMUC could continue to purchase at Tier 2 rates. As of FY 20/21, OMUC 1675
Ontario Municipal Utilities Company Section 3
Water Supply Assessment for West Haven Specific Plan Amendment Water Supply Analysis 27 purchased 5,851 AF (5.22 mgd) of wholesale water from the WFA (OMUC(a)). The actual and projected wholesale water supplies that are projected to be available to WFA through 2045 are shown in Table 3-1.

To reduce dependence on imported water supplies, OMUC joined the “Dry Year Yield Storage Program,” which is described below.

Dry Year Yield Storage Program
The Dry Year Yield (DYY) storage program is a cooperative Conjunctive Use Program Agreement between MWD, IEUA, Chino Basin Watermaster, Three Valleys Municipal Water District, and the Chino Basin groundwater producers (Agreement No. 49960 [DYY 2014]). Under the DYY Program, MWD can store up to 100,000 AFY of water in the Chino Groundwater Basin during wet years when surplus water is available, and to reduce imported water deliveries up to 33,000 AFY in dry, drought, or emergency periods, but not to exceed the amount of water in the MWD storage account (OMUC 2020 UWMP, p. 6-18).

The City executed an agreement with IEUA to participate in the DYY program in 2003.

The DYY Agreement was amended in September 2014 to clarify storage measurement and extraction from the MWD storage account, define baseline conditions in calculations of performance targets, define procedures for variances in performance targets, revise administrative milestones, and make miscellaneous updates (refer herein to for original agreement and amendments). The 2014 DYY amendments also 1676
Ontario Municipal Utilities Company Section 3
Water Supply Assessment for West Haven Specific Plan Amendment Water Supply Analysis 28 provided for a minimum imported water delivery of 40,000 AFY during “call” years, establishing minimum needs for direct deliveries from MWD. As of June 30, 2020, the storage balance in the DYY account is 45,961 AF (OMUC 2020 UWMP, p. 6-18).

Participation in the DYY program obligates OMUC to reduce its use of imported water from WFA by a fixed amount, known as the “shift obligation” when MWD makes a “call” for their water stored in the Chino Basin. OMUC’s shift obligation is 8,076 AFY, which is the amount OMUC purchases from WFA during a baseline year (OMUC 2020 UWMP, p. 6-33). OMUC purchases an additional 2,000 AFY from WFA that is then sold to neighboring water supplier Jurupa Community Services District (JCSD) who does not have an imported water connection. In 2014, JCSD entered into an agreement with the City to participate in the DYY program (a copy of which is located in Appendix L).

During years when MWD makes a “call” for the water in their storage account, OMUC will decrease its purchase of WFA imported water by a combined total of 10,076 AF (8,076 AF plus 2,000 AF) compared to the previous year. To meet its obligation in the DYY program during a “call” year, JCSD will deliver 2,000 AF to OMUC from the Chino Basin Desalter Authority (CDA).
3 DYY funds from DWR local assistance grants were used for the construction of three OMUC groundwater wells (Wells 45, 46, and 47) and an ion-exchange facility located at John Galvin Park to treat water extracted from Wells 44 and 52. When MWD makes a “call” for its stored water, OMUC can operate these facilities to meet its shift obligation. MWD will then pay for the cost of operations and OMUC would pay MWD (through IEUA) the full-service water rate. OMUC can use the DYY facilities to meet its normal water demands during other periods, but OMUC is responsible for the well operation and maintenance costs (OMUC 2020 UWMP, p. 6-33). 3 Assuming JCSD’s imported water baseline is 2,000 AFY (JCSD 2014). 1677
Ontario Municipal Utilities Company Section 3
Water Supply Assessment for West Haven Specific Plan Amendment Water Supply Analysis 29 The additional groundwater capacity provided by this program allows OMUC to increase the percentage supply used to meet peak demands and allow OMUC to be less reliant upon imported water supplies (OMUC 2020 UWMP, p. 6-33).

3.2. Documenting Water Supplies
As of the 2020 UWMP, approximately 46 percent of OMUC’s water supply came from groundwater, 34 percent from imported water, and 20 percent of supply was recycled water (OMUC 2020 UWMP, p. 6-37).

The recorded water supplies available to OMUC from 2000 to FY 20/21 are provided in Table 3-2 (next page) and the projected water supplies available to OMUC from 2025- 2045 are provided in Table 3-3. In addition, each water supply source is identified as a water supply entitlement, water right, or water service contract per SB 610 guidance.

Appropriative rights to groundwater are discussed in Chapter 4 – Groundwater Analysis.

(a) According to SAWCo’s 2020 UWMP, the estimated projected annual water demands for OMUC for 2025 through 2045 is 601 AFY.

OMUC anticipates increasing its total water supply by pursuing: 1) full utilization of OMUC’s groundwater rights in the Chino Basin allowed under the Chino Basin Groundwater Adjudication Judgment (including increased groundwater recharge with stormwater and recycled water described in Section 4); 2) expanding use of recycled water; and 3) expanding use of desalter water (OMUC 2020 UWMP, p. 6-38).

Water Supply Capacities
The capacity of each source of supply available to OMUC is provided in the 2020 Ontario Water Master Plan (AKM 2020), which is provided in Appendix B. The capacity of the supply system refers to the maximum production rate based on the pumps and infrastructure. For example, the capacity of groundwater wells refers to a pumping rate based on running the pumps at full utilization, 24-hours a day, 7 days a week. Although this maximum rate of pumping is assumed in terms of comparing capacities, pumps are rarely used at more than two-thirds capacity. Knowing the system capacity is 1680
Ontario Municipal Utilities Company Section 3
Water Supply Assessment for West Haven Specific Plan Amendment Water Supply Analysis 32 important to ensure OMUC can meet all demands imposed upon the system, specifically meeting “average day demand” and “maximum day demand.” Demand can be met with multiple supply sources, storage, or a combination of both. OMUC’s reservoirs are not discussed in this Assessment, however, according to the master plan they are used to regulate hourly fluctuations in demand, provide fire flow, and supplement supply during an extended outage of a source (AKM 2020, p. 7-3).

According to the 2020 Water Master Plan, OMUC is required to meet the following water supply criterion from the California Code of Regulations Related to Drinking Water: “a minimum source of supply equal of one maximum day demand of the service area (AKM 2020, p. 10-1). Further, OMUC has set a design criterion in its 2020 Water Master Plan that “requires a source of supply equal to one average day demand (19,280 gpm) from local sources” (AKM 2020, p. 10-1). As the land uses and population changes in OMUC service area, so does the average and maximum day demands. The existing (2020) maximum capacities of existing sources of supply available to OMUC are provided in Table 3-4.

(a) Assuming wells operate 24 hours per day for 365 days per year.

As described in the 2020 Ontario Water Master Plan, the combined ultimate capacity of existing and future wells is approximately 68,404 gpm (Table 3-5), which is about 192% of the future average day demand (35,716 gpm) and therefore meets the City and state supply criterion for average day demand coming from local sources (p. 12-1).

OMUC confirmed for this Assessment that the capacities shown in Tables 3-4 and 3-5 have not changed since the 2020 Water Master Plan.

In addition, the ultimate supply capacity is equivalent to 84,395 gpm, which is about 154% of the City’s future maximum day demand (54,778 gpm); therefore, the City is capable of providing the full projected maximum day demand (AKM 2020, p. 12-1).

However, under ultimate conditions the supply capacity will require additional future wells, as shown in Table 3-5 to meet the water supply criterion for maximum day demand.

3.3. Descriptions of All Water Supply Projects
City Well Production
OMUC currently owns 17 active groundwater wells in the Chino Basin (AKM 2020, p. 6- 1). The Chino Basin is one of the largest groundwater basins in southern California, 1682
Ontario Municipal Utilities Company Section 3
Water Supply Assessment for West Haven Specific Plan Amendment Water Supply Analysis 34 with an estimated 5 million AF,4 with another 1 million AF in additional storage capacity. OMUC is planning seven new wells in the 925 Pressure Zone serving Ontario Ranch with a combined additional supply capacity of 48,068 AFY (Table 3-5) (AKM 2020, p. 12-1).

In FY 20/21, OMUC pumped 17,171.1 AF from the Chino Basin (CBWM 2021, p. 9.1).

OMUC’s existing (2020) well capacity is approximately 62,269 AFY (Table 3-4).5 The recorded extractions from OMUC wells between 2016 and 2021 are shown in Table 3-

As of 2020, approximately 46 percent of OMUC water supply came from groundwater pumped by OMUC wells in the Chino Basin. OMUC strives to maximize local water supplies and minimize the need for imported water from other regions (OMUC 2020 UWMP, p. 1-5). A thorough description of the City’s groundwater rights pursuant to SB 610 guidance is provided in Section 4 – Groundwater Analysis.

Chino Basin Desalter Authority (CDA) Groundwater Production OMUC is a member of the CDA, a joint exercise of powers agency created on September 25, 2001, along with JCSD, Santa Ana River Water Company, IEUA and the 4 The 2020 Safe Yield Recalculation Final Report (May 15, 2020) indicates the estimated total volume of water in storage was 12.6 million AF in July 2018 (WEI 2020, p. 6-15). 5 Assuming wells operate 24 hours per day for 365 days per year. 1683
Ontario Municipal Utilities Company Section 3
Water Supply Assessment for West Haven Specific Plan Amendment Water Supply Analysis 35 cities of Chino, Chino Hills, and Norco. Western Municipal Water District joined CDA on April 2, 2009. The goals of the CDA are:
• Achieve hydraulic control of the Chino Basin to prevent contaminated Chino Basin groundwater from entering Santa Ana River;
• Remove contamination (primarily nitrates, as well as TCE, PCE, and TCP) from groundwater in the southern portion of the Chino Basin; and • Deliver the treated water to member agencies to offset the need for imported water.

CDA provides high-quality drinking water to CDA members through “take or pay” contracts. CDA operates 30 wells and two desalters (salt removers) that treated approximately 35,003 AF of Chino Basin groundwater in 2020 (CDA 2020 UWMP, p. 6- 27). In the future, “CDA will pump up to 40,000 AFY of contaminated groundwater from the Chino Basin for water quality management purposes, groundwater cleanup, and hydraulic control required by the Regional Water Quality Control Board. CDA will provide up to 35,200 AFY of treated water to its member agencies” (CDA 2020 UWMP, p. 6-27).

The Chino I Desalter, located at 6905 Kimball Avenue in Chino, was completed in 2000 and expanded in August 2005 to its current rated capacity of 14.2 mgd (CDA 2020 UWMP p. 6-8). However, the Chino I Desalter cannot provide this rated capacity due to the high total dissolved solids (TDS) in the raw groundwater supply. The Chino II Desalter was completed in 2006 and is located at 11202 Harrel Street in the City of Jurupa Valley. The current rated capacity of Chino II Desalter is 33 mgd (CDA 2020 UWMP, p. 6-8).

Although Chino Desalter I capacity will not be increased, additional raw water capacity is provided by five new CDA wells in the Chino Creek Well Field. All five wells have been drilled and equipped.
1684
Ontario Municipal Utilities Company Section 3
Water Supply Assessment for West Haven Specific Plan Amendment Water Supply Analysis 36 According to the 2020 UWMP, in FY 19/20 OMUC purchased approximately 6,636 AF from CDA. OMUC purchased approximately 7,337 AF from CDA in FY 20/21 (Table 3- 2). As shown in Table 3-3, the water supply from CDA to OMUC is projected to stabilize at 8,533 AFY by 2025, which would be roughly 16 percent of the total water supply portfolio for OMUC in 2025. The City’s capacity rights to CDA are described in Section 4 – Groundwater Analysis.

Inland Empire Utilities Agency (IEUA) Recycled Water Supply OMUC purchases recycled water supplies from IEUA, which treats the City’s wastewater at its four regional wastewater reclamation plants. IEUA provides wastewater treatment services to seven Contracting Agencies, including the City of Ontario. OMUC has been using recycled water produced by IEUA since 1972.

Currently, recycled water is used in the City for agricultural irrigation, landscape irrigation, golf course irrigation and industrial purposes. “Pursuant to the Chino Basin Regional Sewage Service Contract, each Contracting Agency has the right of first purchase of their Base Entitlement. Base Entitlement is defined as the total quantity of sewage delivered into the Regional Sewerage System by the Contracting Agency less normal processing losses resulting from the treatment of sewage” (OMUC 2020 UWMP, p. 6-21). In FY 19/20, this amount was 12,645 AF (OMUC 2020 UWMP, p. 6-24) and in FY 20/21 this amount was 12,854 AF (OMUC(a)).

In FY 19/20, 7,812 AF of recycled water was purchased by OMUC for direct use (Table 3-2) and then 8,556.74 AF in FY 20/21 (OMUC(b)). This represents about 67 percent utilization of recycled water supply available to OMUC in FY 20/21, which is an increase from roughly 62 percent utilization in FY 19/20. Recorded and projected supplies of recycled water available to OMUC are listed in Table 3-7. 1685

Over the next 20 years, landscape irrigation is projected to have the greatest increase in demand for recycled water followed by industrial use within the OMUC service area.

Agricultural properties are expected to convert to more urban land uses, while supplies to golf courses are expected to remain relatively stable. (OMUC 2020 UWMP, p. 6-28).

IEUA has prepared recycled water studies, plans, and strategy documents to bring a regional recycled water delivery system to fruition. OMUC updated their Recycled Water Master Plan in 2020 (located in Appendix C) to fully coordinate with IEUA’s recycled water planning efforts.

San Antonio Water Company (SAWCo) Potable Water Supply
SAWCo is a mutual water company and corporation located in Upland. SAWCo has provided water service to its active shareholders for over 135 years. Although SAWCo does not technically meet the threshold as a retailer or wholesale water agency that needs to prepare an UWMP, they have done so nonetheless in 2020.

SAWCo supplies water based on entitlement only, which is based on the number of shares held. The number of shares is finite and considered a commodity that can be divided or sold. The “entire water of the company” and the current entitlement for 1686
Ontario Municipal Utilities Company Section 3
Water Supply Assessment for West Haven Specific Plan Amendment Water Supply Analysis 38 2020 is equivalent to 12,570 AFY, which distributed among the 6,178 shares. The volume per share is subject to change (OMUC 2020 UWMP, p. 6-8).

The City owns 295 shares of SAWCo, which equates to a current entitlement of 600 AFY of potable water to OMUC (OMUC 2020 UWMP, p. 6-8). In FY 19/20, OMUC received an actual volume of 600 AF (Table 3-2). In FY 20/21, OMUC received 500 AF from SAWCo (OMUC(a) 2022). OMUC has forecasted that future available supplies will be 600 AFY from 2025 to 2045 (Table 3-3). The City receives water from SAWCo indirectly through a connection made in 2015 from SAWCo to the WFA.

SAWCo water supplies are a mixture of potable and non-potable water from San Antonio Creek, the San Antonio Tunnel and three groundwater basins: Chino Basin, Cucamonga Basin and Six Basins (OMUC 2020 UWMP, p. 6-9). No new sources of supply are anticipated to be developed by SAWCo over the planning horizon. Actual supply available to SAWCo in 2020 totaled 2,584 AF of potable supply and 13,762 AF of non-potable supply. In their 2020 UWMP, SAWCo estimates for 2025 and 2030 that total reasonably available supplies will be 15,260 AFY (SAWCo 2020 UWMP, p. 5-10).

In terms of future reliability, SAWCo has stated the following in its 2020 UWMP (p. 6-4):
“SAWCo expects to meet demands under all water year scenarios with existing supply sources.” In addition, SAWCo has future transfer and exchange projects planned to mutually benefit certain shareholders during an emergency, including OMUC. SAWCo is currently constructing several projects to increase storage and capture all raw water released through the Frankish Tunnel. Both projects are anticipated to be completed in early 2021 (SAWCo 2020 UWMP, p. 5-7).

3.4 Documenting Normal Year Water Supply and Demand
OMUC has assumed in its 2020 UWMP that customer water demand and available water supply are equal during “normal” precipitation years. The normal year water supplies available to OMUC, as well as the normal year water demand projections are compared in Table 3-8, which are based on the City’s 2020 Water Use Target of 196 1687
Ontario Municipal Utilities Company Section 3
Water Supply Assessment for West Haven Specific Plan Amendment Water Supply Analysis 39 GPCD for potable water demands (OMUC 2020 UWMP, p. 7-9). OMUC has estimated that sufficient supply will be available during any normal year occurring between 2025 and 2045.

• The ratio of total water supplies (including potable and recycled water supplies) available to the City during a historical normal year in FY 19/20 (39,921 AF) and during a historical single dry year in FY 17/18 (43,346 AF) were used to estimate the City’s projected water demands during single dry years (p. 7-9). • Water losses have been included in the potable water demands as 7 percent of the annual demand.

OMUC has determined that the water demands during single dry years over the next 25 years will be met, as shown in Table 3-9.

3.7 Comparison of Available Water Supply and Demand
CWC section 10910 (c)(3) states: If the projected water demand associated with the proposed project was not accounted for in the most recently adopted UWMP…the water assessment for the project shall include a discussion with regard to whether the public water system’s total projected water supplies available during normal, single dry, and multiple dry water years during a 20-year projection will meet the projected water 1690
Ontario Municipal Utilities Company Section 3
Water Supply Assessment for West Haven Specific Plan Amendment Water Supply Analysis 42 demand associated with the proposed project, in addition to the public water system’s existing and planned future uses, including agricultural and manufacturing uses.

As described in Section 2, the annual potable plus recycled water demand for the proposed Project’s additional units is estimated at 113 AFY; combined with the estimated water demand of the already-approved units in the same PA’s, the total water demand for PA-1 and PA-3 is 258 AFY. In comparison, the total water demand estimated by the previously planned land use of the same area is 145 AFY (Tables 2-4 and 2-5). This net increase of 113 AFY reflects an increase in potable demand of 109 AFY and an increase in recycled water demand of 4 AFY.

As shown in Table 3-3 and Table 3-9, the future water supplies available to OMUC are projected to meet the projected water demands for the service area. Further, the future water demands in the 2020 UWMP did not consider the increase in potable water demand from the proposed Project. However, the increased potable water demand of the Project is just 0.19 percent of the citywide ultimate 2045 water demand/water supply as estimated by the 2020 UWMP (i.e., 57,609 AFY). Likewise, the Project’s additional recycled water demand is 0.02 percent of the citywide ultimate 2045 demand/supply of recycled water (i.e., 16,059 AFY).

As of 2020 OMUC can purchase up to 9,915 AFY (8.9 mgd) of imported supply through WFA at Tier 1 rates. Beyond that amount, OMUC could continue to purchase at Tier 2 rates (ultimate capacity for WFA supply is 15.4 mgd [Table 3-5]). In 2020, OMUC purchased about 6,513 AF from the WFA plant (Agua de Lejos WTP), which is well within their conveyance capacity of 15.4 mgd and within their rights of approximately 25 mgd. There is ample availability for OMUC to purchase additional imported water from the WFA that is within their rights to meet the needs of the proposed Project.

With the signing of AB 1668 and SB 606, the state has set an Indoor Residential Standard of 55 gallons per capita per day (GPCD) which will decrease to 50 GPCD by 2030 (CWC section 10609.4(a)). The per person unit water use factors used by the City are based on a minimum of 60 gpd/person; therefore, a per-person savings of at least 1691
Ontario Municipal Utilities Company Section 3
Water Supply Assessment for West Haven Specific Plan Amendment Water Supply Analysis 43 5 gallons per day of indoor residential potable water use would be achieved. Assuming an ultimate citywide residential population of 362,903 persons (OMUC 2020 UWMP, p. 3-1) and water conservation efforts of at least 5 GPCD over the entire City, approximately 2,033 AFY of water could be conserved. This savings would more than cover the increased and unplanned potable water demand of the proposed Project.

In regard to future agricultural water needs, agricultural properties within the OMUC service area are expected to convert to urban land uses, which is consistent with the City’s General Plan Land Use Plan. Many agricultural operations in the City are on private wells and/or use recycled water. As shown in Table 3-7, recycled water deliveries for agricultural irrigation are projected to decrease to zero in 20 years. In regard to future industrial water needs, industrial land uses (which may include some manufacturing uses) are the third most common type in the City (Table 3-7) and they are planned by the City General Plan to increase (Table 2-3).

Table 3-9 and Table 3-10 show that OMUC projects water supplies during single-dry and multiple-dry years in volumes sufficient enough to meet the demand of the service area over the next 20 years. Section 4 will describe the supply available to OMUC through rights held to Chino Basin groundwater that are greater than the amount currently extracted. OMUC can also bank water and pump in excess of their rights in the Chino Basin with payment of a replenishment fee.

Section 4 will discuss the City’s water rights in light of this water supply and capacity analysis.

Ontario Municipal Utilities Company Section 4
Water Supply Assessment for West Haven Specific Plan Amendment Groundwater Analysis 44 SECTION 4 - GROUNDWATER ANALYSIS
SB 610 requires specific groundwater information to be included in the WSA if groundwater will be a source of water for the proposed project. As discussed in Section 3, groundwater is one of the sources of supply for OMUC and therefore part of the water supply for the proposed Project.

Law
CWC Section 10910 (f):

If a water supply for a proposed project includes groundwater, the following additional information shall be included in the water supply assessment:
(1) A review of any information contained in the urban water management plan relevant to the identified water supply for the proposed project. (2)(A) A description of any groundwater basin or basins from which the proposed project will be supplied. (B) For those basins for which a court or the board has adjudicated the rights to pump groundwater, a copy of the order or decree adopted by the court or the board and a description of the amount of groundwater in the public water system, or the city or county if either is required to comply with this part pursuant to subdivision (b), has the legal right to pump under the order or decree. (C) For a basin that has not been adjudicated that is a basin designated as a high- or medium- priority pursuant to Section 10722.4, information regarding the following: (i) Whether the department has identified the basin as being subject to critical conditions of overdraft pursuant to Section 12924. (ii) If a groundwater sustainability agency has adopted a groundwater sustainability plan or has an approved alternative, a copy of that alternative or plan. (D) For a basin that has not been adjudicated that is a basin designated as low- or very low priority pursuant to Section 10722.4, information as to whether the department has identified the basin or basins as overdrafted or has projected that the basin will become 1693
Ontario Municipal Utilities Company Section 4
Water Supply Assessment for West Haven Specific Plan Amendment Groundwater Analysis 45 overdrafted if present management conditions continue, in the most current bulletin of the department that characterizes the condition of the groundwater basin, and a detailed description by the public water system, or the city or county if either is required to comply with this part pursuant to subdivision (b), of the efforts being undertaken in the basin or basins to eliminate the long-term overdraft condition.
(3) A detailed description and analysis of the amount and location of groundwater pumped by the public water system, or the city or county if either is required to comply with this part pursuant to subdivision (b), for the past five years from any groundwater basin from which the proposed project will be supplied.

The description and analysis shall be based on information that is reasonably available, including, but not limited to, historic use records. (4) A detailed description and analysis of the amount and location of groundwater that is projected to be pumped by the public water system, or the city or county if either is required to comply with this part pursuant to subdivision (b), from any basin from which the proposed project will be supplied.

(5) An analysis of the sufficiency of the groundwater from the basin or basins from which the proposed project will be supplied to meet the projected water demand associated with the proposed project. A water supply assessment shall not be required to include the information required by this paragraph if the public water system determines, as part of the review required by paragraph (1), that the sufficiency of groundwater necessary to meet the initial and projected water demand associated with the project was addressed in the description and analysis required by subparagraph D, paragraph (4) of subdivision (b) of Section 10631. 1694
Ontario Municipal Utilities Company Section 4
Water Supply Assessment for West Haven Specific Plan Amendment Groundwater Analysis 46 4.1 Review of Urban Water Management Plan (CWC Section 10910(f)(1)) The City’s 2020 UWMP, prepared by AKM on behalf of the City of Ontario (OMUC) was adopted by City Council Resolution 2021-036 and 2021-037 on June 1, 2021 (located in Appendix A). The UWMP includes information relevant to the identified water supply for the proposed Project and is incorporated herein. Relevant information includes: 1) current and projected water demands (Water Use Characterization) through year 2045; 2) a description of the Chino Groundwater Basin (Water Supply Characterization); 3) the reliability of the water supply, projected supply and demand comparisons, and water shortage plans (Water Service Reliability and Drought Risk Assessment and Water Shortage Contingency Plan); and 4) water demand management efforts (Demand Management Measures).6 The ultimate water demand projections of the 2020 UWMP are based on the findings of the City’s 2020 Water Master Plan (AKM 2020) and 2020 Recycled Water Master Plan (Stantec 2020).

4.2 Groundwater Basin Descriptions (CWC Section 10910(f)(2)) The Chino Groundwater Basin is the direct source of groundwater for OMUC. Although water supplied to OMUC from SAWCo may include a combination of groundwater from other basins (i.e., San Antonio Tunnel, Cucamonga Basin, and Six Basins), the amount is minimal, and the basins are described in the 2020 SAWCo UWMP (located in Appendix H).

Chino Groundwater Basin Description
The Chino Basin covers approximately 240 square miles in the upper Santa Ana River Watershed, and underlies parts of Los Angeles, San Bernardino, and Riverside Counties. The state Department of Water Resources (DWR) identifies the Chino Basin as Basin No. 8-002.01, which is a sub-basin of the Upper Santa Ana Valley (Bulletin 118).7
It is estimated the Chino Basin has approximately 5 million AF of water in 6 Words and phrases italicized in parentheses are in reference to chapters so titled in the 2015 UWMP. 7 DWR collects, summarizes, and evaluates groundwater data in the “Bulletin 118” series, which present the results of basin evaluations and defines the boundaries of California’s 515 alluvial groundwater basins. An update was provided in 2016. In Bulletin 118, DWR identifies each basin and sub-basin with a number code. 1695
Ontario Municipal Utilities Company Section 4
Water Supply Assessment for West Haven Specific Plan Amendment Groundwater Analysis 47 storage, and an estimated 1 million AF of additional unused storage capacity.8 While still considered a single basin for hydrologic purposes, the Chino Basin is divided into five management zones by the California Regional Water Quality Control Board , Santa Ana Region based on similar hydrologic conditions. Geographically speaking, the City is located in the approximate center of the Chino Basin. DWR Bulletin 118 (2016 update, p. 1) describes the Chino Basin as follows:

The subbasin [Chino Basin] is bound on the northwest by the San Jose fault, on the north by the Cucamonga fault and impermeable rocks of the San Gabriel Mountains, and on the east by the Rialto-Colton fault. The basin is bound on the southeast by the Jurupa Mountains, Pedley Hills, La Sierra Hills, and the approximate location of the Santa Ana River. The Chino fault and impermeable rocks of the Chino Hills and Puente Hills bound the southwest side of the basin. In some areas, the basin boundary coincides with the Chino Basin (1978) groundwater adjudication boundary.

The Chino Basin is an adjudicated basin and has been extensively studied by the court-appointed Chino Basin Watermaster (CBWM), with reports available at www.cbwm.org. The following is an excerpt that describes the Chino Basin geology from the Chino Basin Watermaster’s management plan called the “Optimum Basin Management Program” or “OBMP” (1999, p. 2-2):

Chino Basin was formed when eroded sediments from the San Gabriel Mountains, the Chino Hills, Puente Hills, and the San Bernardino Mountains filled a structural depression…The bottom of the Basin – the effective base of the freshwater aquifer – consists of impermeable sedimentary and igneous rocks. The base of the aquifer is overlain by older alluvium of the Pleistocene period followed by younger alluvium of the Holocene period. 8 The 2020 Safe Yield Recalculation Final Report (May 15, 2020) indicates the estimated total volume of water in storage was 12.6 million AF in July 2018 (WEI 2020, p. 6-15). 1696
Ontario Municipal Utilities Company Section 4
Water Supply Assessment for West Haven Specific Plan Amendment Groundwater Analysis 48 The younger alluvium varies in thickness from over 100 feet near the mountains to a just few feet, south of Interstate 10 and generally covers most of the north half of the Basin in undisturbed areas. The younger alluvium is not saturated and thus does not yield water directly to wells.

Water percolates readily in the younger alluvium and most of the large spreading basins are located in the younger alluvium.

The older alluvium varies in thickness from about 200 feet thick near the southwestern end of the Basin to over 1,100 feet thick southwest of Fontana, and averages about 500 feet throughout the Basin.

Legal Right to Pump from the Chino Basin
Water rights to the Chino Basin were adjudicated by the Superior Court of the State of California for the County of San Bernardino in 1978 (a copy of the Judgment and amendments thereto are provided in Appendix M). The court’s Judgment declared the Safe Yield of the Chino Basin at 140,000 acre-feet per year (AFY).9 Withdrawal in excess of Safe Yield is termed Overdraft. The Chino Basin Watermaster may determine that the Operating Safe Yield (OSY) can be higher from year-to-year depending on factors including favorable precipitation and management efforts that maximize the beneficial use of the groundwater Basin.10 The Chino Basin Watermaster has undertaken a safe yield redetermination. In July 2020, the court ordered that the safe yield be reduced by 3% and reset to 131,000 AFY for the period of July 1, 2020, to June 30, 2030. The court previously reset the safe yield from its initial 140,000 AFY to 135,000 AFY in 2017 for the period of 2010 to 2020.

The Chino Basin Watermaster is comprised of three stakeholder groups (or “pools”):

Overlying Agricultural Pool Committee (representing dairymen, farmers, and the State 9 Judgment (1978) defines Safe Yield as, “The long-term average annual quantity of groundwater (excluding replenishment or stored water but including return flow to the Basin from use of replenishment or stored water), which can be produced from the basin under cultural conditions of a particular year without causing an undesirable result.”
10 Judgment (1978) defines Operating Safe Yield (OSY) as, “The annual amount of groundwater which Watermaster shall determine, pursuant to criteria specified in Exhibit “I”, can be produced from Chino Basin by the Appropriative Pool parties free of replenishment obligation under the physical solution herein.” 1697
Ontario Municipal Utilities Company Section 4
Water Supply Assessment for West Haven Specific Plan Amendment Groundwater Analysis 49 of California); the Overlying Non-Agricultural Pool Committee (representing businesses and industries); and the Appropriative Pool Committee (representing local cities, public water districts and private water companies). The Chino Basin Watermaster carries out the provisions of the Judgment including monitoring of the Chino Basin and files an annual report on pumping and replenishment.

The City is a member of both the Overlying Non-Agricultural Pool and the Appropriative Pool. The Judgment allocates a portion of the Safe Yield to the Overlying NonAgricultural Pool and a portion of the OSY to the Appropriative Pool. Pursuant to the Judgment, the City has appropriative rights to 20.742 percent of the OSY allocated to the Appropriative Pool. The City has gained 53.338 percent of the Safe Yield assigned to the Overlying Non-Agricultural Pool (CBWM 44th Annual Report, p. N-8). The assigned share of the Safe Yield and OSY change depending on the Safe Yield set by the court.

The Judgment allocates the Safe Yield of the Chino Basin according to the three pools as described above (Appendix M, Paragraph 13). The members of each pool are then enjoined from producing water from the Chino Basin in excess of such allocated amount "except pursuant to the provisions of the Physical Solution" (Appendix M, Paragraph 13(a)-(c)).

The Physical Solution of the Judgment is described in broad terms by Paragraphs 39 through 57 of the Judgment. Paragraph 45 provides the Chino Basin Watermaster with the authority to levy and collect assessments for the purchase of water necessary to balance the production by any party in excess of that party's allocated share of Safe Yield of the Chino Basin. Paragraphs 49 and 50 then describe the sources of water which are authorized to function as sources of replenishment water and methods by which water can be replenished to the Chino Basin. Exhibit H, Paragraph 7, of the Judgment describes the way in which costs for replenishment water will spread among the members of the Appropriative Pool.
1698
Ontario Municipal Utilities Company Section 4
Water Supply Assessment for West Haven Specific Plan Amendment Groundwater Analysis 50 The afore-cited paragraphs of the Judgment evince a clear expectation that parties, including the City/OMUC, would produce water in excess of their adjudicated production rights. The injunction in Paragraph 13 of the Judgment should thus be interpreted to mean that parties are enjoined from producing water in excess of their adjudicated rights except to the extent that they will pay a replenishment assessment.

The ability to produce water from the Chino Basin is accordingly not a matter of availability, as contemplated and sanctioned by the Judgment for the reasons discussed above, but rather a matter of cost. Water produced in excess of production rights will cost more than water produced within a party's production rights. Thus, the quantity and reliability of groundwater supplies under the Judgment for purposes of this Assessment is a matter of cost of the water produced from the Chino Basin rather than limitations on production which may otherwise operate to reduce the sufficiency of the groundwater supply.

In addition to the water supplies described in Section 3, OMUC has rights to groundwater held in the Chino Basin as described below (from Chino Basin Watermaster’s (CBWM) Approved 2021/2022 Assessment Package for Production year 2020/2021, dated Nov. 18, 2021) and in Table 4-1:
• Appropriative Right. The City has appropriative rights to 20.742 percent of the OSY allocated to the Appropriative Pool. As of FY 20/21, the OSY is 40,834 AF; therefore, the City’s assigned share is 8,469.8 AF (CBWM 2021, p. 10.1). To supplement the 2017 decrease in safe yield, the City currently receives an additional 1,866.8 AFY transferred from unproduced Agricultural Pool rights (“Safe Yield Reduction”) (CBWM 2021, p. 16.1).
• Overlying Non-Agricultural Right. The City has purchased and has rights to

53.338 percent of the Safe Yield assigned to the Overlying Non-Agricultural Pool, which is currently 7,350.3 AFY. As of FY 20/21, the City’s assigned share is 3,920.6 AF (CBWM 2021, p. 4.1).
1699
Ontario Municipal Utilities Company Section 4
Water Supply Assessment for West Haven Specific Plan Amendment Groundwater Analysis 51 • Land Use Conversions. The City gains rights to additional Chino Basin groundwater as a result of land use conversions from agricultural to nonagricultural uses. This is expected to increase from development of Ontario Ranch; the total of which is adjusted annually by the Watermaster. As of FY 20/21, the City received 4,668.3 AF from land use conversions (CBWM 2021, p.

15.1).
• Annual Early Transfers. The Chino Basin Watermaster can approve an “Early Transfer” of water to the Appropriative Pool equal to the quantity of water not produced by the Overlying Agricultural Pool that is remaining after all land use conversions are satisfied, pursuant to the Peace Agreement.11 The Early Transfer Water is annually allocated among the Appropriative Pool members in accordance with their pro-rata share of the initial Safe Yield. For the City, this is

20.742 percent of the “early transfer” water that the Watermaster may transfer from the Overlying Agricultural Pool (OMUC 2020 UWMP, p. 6-10). The amount available for transfer changes from year to year but is projected to increase. In FY 20/21, the City received 4,272.6 AFY as its share of Early Transfer (CBWM 2021, p. 16.1).
• Groundwater Recharge Credits. The City is entitled to water rights due to groundwater recharge with stormwater and recycled water in the Chino Basin.

The credited amount is based on the volume recharged and therefore varies annually but is projected to increase over time. In FY 2018/2019, 2,544 AF of recycled water was recharged for the City. In FY 19/20 and FY 20/21, no 11 In 2007, the parties to the Chino Basin Judgement approved the “Peace Agreement” which is a set of measures proposed by Chino Basin Watermaster to supplement the OBMP Implementation Plan. Focus for the measures were placed on achieving hydraulic control (reduction of groundwater discharge from the Chino North Management Zone to the Santa Ana River). To achieve hydraulic control, re-operation (controlled overdraft) of the groundwater basin is proposed. Strategically placed wells would be constructed in the basin and the groundwater would be pumped to the Desalter to improve the longterm reliability of the basin. 1700
Ontario Municipal Utilities Company Section 4
Water Supply Assessment for West Haven Specific Plan Amendment Groundwater Analysis 52 recharge was credited to the City (OMUC 2020 UWMP, p. 6-11; CBWM 2021, p.

12.1).
• Fontana Recycled Water Rights. The City has a long-term contract to purchase up to 3,000 AFY of recharged recycled water rights from the City of Fontana (a copy of which is in Appendix N). The City of Fontana does not operate a water system. The amount purchased by OMUC each year will vary. In FY 2018/2019, the City purchased 2,157 AF of Fontana’s recycled water entitlement. In FY 19/20 and FY 20/21, no recharged water rights were purchased (OMUC 2020 UWMP p. 6-12; CBWM 2021, p. 12.1). • Groundwater Storage Accounts. The City has rights to store water in the Chino Basin (Appropriative and Overlying Non-Agricultural) and has been increasing its various storage accounts in recent years. The City holds water in both local storage accounts and supplemental accounts. Local storage accounts hold un-pumped OSY groundwater rights and stormwater that has been recharged into the Chino Basin. Supplemental accounts hold both imported water and recycled water that has been recharged into the Chino Basin. As of June 30, 2021, the City has 96,992.4 AF in storage pursuant to Appropriative rights (CBWM 2021, pp. 11.1, 12.1). In addition, there is 1,918.0 AF in storage pursuant to Overlying Non-Agricultural rights (CBWM 2021, p.

5.1).

Water Supply Assessment for West Haven Specific Plan Amendment Groundwater Analysis 54 4.3. Recorded Use of Groundwater by City of Ontario (CWC Section 10910 (f)(3)) The City's groundwater supply currently comes from 17 active groundwater wells located throughout the OMUC service area within the Chino Basin. As of FY 19/20, OMUC produced 18,395.3 AF from the basin (OMUC 2020 UWMP, p. 6-3) and in FY 20/21, 17,171.1 AF was produced (CBWM, p. 8.1). The recorded groundwater production has generally decreased from 36,842 AFY in 2000, as shown in Chart 4-1.

Chart 4-1 - Annual OMUC Groundwater Production, 2000 - 2021, (AFY) (Sources: 2000-2009 from the 2012 Ontario Water Master Plan; 2010 from OMUC 2010 UWMP; 2011- 2020 from OMUC 2020 UWMP, p. 6-3; 2021 from CBWM 2021, p. 8.1.)

4.4. Projected Use of Groundwater by the City of Ontario (CWC Section 10910(f)(4)) The proposed Project will receive water from a combination of the City's supply sources including groundwater wells, imported water from WFA, treated groundwater from CDA, and recycled water from IEUA.

Projected groundwater use by OMUC will continue as noted in Table 3-3. The use of groundwater will continue to be dependent upon the cost of extracting, treating, and 1703
Ontario Municipal Utilities Company Section 4
Water Supply Assessment for West Haven Specific Plan Amendment Groundwater Analysis 55 transporting the water to customers. Groundwater from the Chino Basin will be utilized by OMUC either directly by pumping into its distribution system or by treating the groundwater (Wells 44 and 52) at the John Galvin Ion Exchange Plant and then pumping the treated groundwater into the City distribution system. The current and ultimate production capacity of OMUC wells is sufficient to meet current and ultimate demand (Table 3-4).

As shown in Table 4-1, the amount of water that OMUC expects to withdraw from the Chino Basin is well within appropriate right pursuant to the Chino Basin Adjudication of 1978 (Appendix M). In addition to its well production, OMUC will also purchase treated Chino Basin groundwater from CDA. OMUC has 1,500 AFY capacity rights in the Chino I Desalter and 7,033 AFY capacity rights in the Chino II Desalter. Projected use of groundwater via CDA is projected to remain at no more than 8,533 AFY (OMUC 2020 UWMP, p. 6-6).

4.5. Sufficiency of Groundwater Basin (CWC Section 10910(f)(5)) The City’s legal right to pump water in an amount necessary to meet all demands as sanctioned and protected by the Judgment as discussed above, is buttressed by several programs and projects directed at ensuring the sufficiency of groundwater supplies from the Chino Basin, particularly during dry years. An adjudicated water right has perhaps the most substantial indicia of reliability of any water right that currently exists in California. An adjudicated right is based upon long-term studies whose purpose it is to protect the long-term functionality of the water source. These rights are coordinated in an established and binding manner with all the other users of the Chino Basin and are overseen by Chino Basin Watermaster which has the authority to mandate and proscribe activities whose purpose is to protect the water source and maximize its long-term beneficial use.

All Chino Basin Watermaster processes are governed by Rules and Regulations and receive active oversight from the Court which, as noted above, retains continuing jurisdiction over the administration of the Judgment. Consequently, the sufficiency of 1704
Ontario Municipal Utilities Company Section 4
Water Supply Assessment for West Haven Specific Plan Amendment Groundwater Analysis 56 the groundwater is not only directed by rigorous Chino Basin Watermaster management processes but validated and ensured by continuing Court oversight.

The OBMP for the Chino Basin has guided the Chino Basin Watermaster’s activities since its adoption in 1998. Chino Basin Watermaster-led basin management activities to ensure the maximization of safe yield and OSY of the Chino Basin include objectives, projects, and programs identified in the Peace Agreement and the OBMP.

Progress is reported in annual reports, biennial, and triennial reports. The key programs include:
1) a comprehensive monitoring program.
2) a comprehensive recharge program.
3) development and implementation of a water supply plan for impaired areas of the Chino Basin.
4) development and implementation of a comprehensive groundwater management plan for Management Zone 1.
5) development and implementation of a regional supplemental water program. 6) development and implementation of cooperative programs with the California Regional Water Quality Control Board – Santa Ana Region and other agencies to improve Basin management.
7) development and implementation of a salt management program. 8) development and implementation of a groundwater storage program; and 9) development and implementation of storage and recovery programs.

As stated, the referenced elements of the OBMP collectively comprise a comprehensive regimen directed to ensuring and maximizing the long-term beneficial use of water in the Chino Basin. In particular, and specific to the location of current and future groundwater production facilities upon which the City relies or will rely to provide water to meet water demands within its service area, OBMP Program Element No. 3, “Develop and Implement Water Supply Plan for the Impaired Areas of the Chino Basin” and Program Element No. 5, “Develop and Implement Regional Supplemental Water 1705
Ontario Municipal Utilities Company Section 4
Water Supply Assessment for West Haven Specific Plan Amendment Groundwater Analysis 57 Program”, address the sufficiency of groundwater from the Chino Basin.

Fundamentally, the goal of Program Elements 3 and 5 is to (2020 OBMP, p. 6):

To maintain and enhance Safe Yield with a groundwater desalting program that is designed to replace declining agricultural groundwater pumping in the southern part of the basin with new pumping to meet increasing municipal water demands in the same area, to minimize groundwater outflow to the Santa River, and to increase Santa Ana River recharge into the basin.

To improve the regional conveyance and availability of imported water and recycled waters throughout the basin.

The achievements from the implementation of the 2000 OBMP for Elements 3 and 5 are summarized below (2020 OBMP, Appendix A, pp. 5 – 6).

Program Element 3 Develop and Implement Water Supply Plan for Impaired Areas (Groundwater Desalting): The objectives of this Program Element are to maintain and enhance the Safe Yield of the basin. The groundwater desalting program was designed to replace declining agricultural groundwater pumping in the southern part of the basin with new groundwater pumping to meet increasing municipal water demands in the same area. The new wells used in the groundwater desalting program were constructed in strategic locations to minimize groundwater outflow to the Santa Ana River and to increase the Santa Ana River recharge into the basin.

In 2000, the groundwater desalting program included a 6,000 AFY treatment plant and a series of wells constructed in the southern part of the Chino Basin near the Chino Airport. Under the OBMP, as of 2018, the desalting program has grown to two treatment plants and additional wells that in aggregate pump and treat about 30,000 AFY degraded groundwater, and the program will reach the OBMP objective of 40,000 AFY in 2019. The groundwater desalting program facilities are owned by the Chino Basin Desalter Authority (CDA).
1706
Ontario Municipal Utilities Company Section 4
Water Supply Assessment for West Haven Specific Plan Amendment Groundwater Analysis 58 Program Element 5: Develop and Implement Regional Supplemental Water Program (Recycled Water Reuse): The objective of this Program Element is to improve the regional conveyance and availability of imported and recycled waters throughout the basin. Since 2000, the IEUA has constructed and operated a recycled water conveyance system throughout the basin enabling it to provide recycled water to its member agencies. Recycled water deliveries grew from about 3,400 AFY in 2000 to about 34,000 AFY in 2017. The recycled water provided by the IEUA has replaced a like amount of groundwater and imported water that would have been otherwise been used for non-potable purposes. Much of the post-2000 increase in supplemental water storage in the Chino Basin is attributable to the increased availability of recycled water. Recycled water is more reliable than imported water, and thus using it in lieu of imported water has improved the sustainability of the Chino Basin and water supply reliability.

Improvements in the regional conveyance and availability of imported water were not achieved.

As indicated in the foregoing OBMP text, the City overlies groundwater supplies in the southern part of the Chino Basin which must be pumped for purposes of meeting new demands, maintaining safe yield, and to protect water quality in the Santa Ana River.

As agricultural production in the southern part of the Chino Basin has declined, it is necessary for these reasons to increase production for municipal uses. This is being achieved through CDA’s Chino I and Chino II Desalters, of which the City has a contractual right to purchase 8,533 AFY pursuant to the 2001 “Joint Exercise of Powers Agreement Creating the Chino Basin Desalter Authority” and subsequent agreements. Thus, not only was increased Chino Basin water production by the City foreseen in the OBMP but sanctioned and encouraged for purposes of achieving OBMP objectives.

The sufficiency of the groundwater supply that is available to OMUC is assured due to the abundance of groundwater in the central and southern portion of the Chino Basin, OBMP objectives that prioritize and assure production from the southern Chino Basin, 1707
Ontario Municipal Utilities Company Section 4
Water Supply Assessment for West Haven Specific Plan Amendment Groundwater Analysis 59 coupled with desalting and ion-exchange treatment facilities that enable the use of this abundant supply for municipal (potable) purposes. As indicated in the quoted text of the OBMP, southern basin production, where the City is partially located, is the linchpin of several critical OBMP objectives. Thus, the sufficiency of groundwater is heightened and prioritized by the necessity of continued pumping from the southern Chino Basin under the OBMP which is administered by the Chino Basin Watermaster and ultimately enforced by continuing court jurisdiction over the Judgment.

The other referenced OBMP Program Elements are collectively directed to ensuring the sufficiency of Chino Basin groundwater supplies, particularly during dry years, and comprehensively address water quality and quantity, thus maximizing beneficial use over the long-term. Sufficiency of groundwater from the Chino Basin is further assured for the following reasons:
• IEUA is a member agency of MWD, which provides imported water from the State Water Project for direct use by parties to the Judgment in the Chino Basin and for Chino Basin recharge purposes (when supplies are available). IEUA has also reviewed the sufficiency of supplies for its service territory that includes the Chino Basin in connection with its 2020 UWMP.
• IEUA’s UWMP is consistent with, and reiterative of, OBMP projects and programs (see Section 4 of IEUA 2020 UWMP in Appendix E). IEUA anticipates increased limitations for imported water for direct and recharge use while noting reductions during dry years (due to increased reliance on groundwater from the Chino Basin) and in the higher amount otherwise required in the absence of OBMP projects and programs. The UWMP also analyzes the sufficiency of water supplies for single and multiple year drought scenarios and concludes the region is expected to meet 100 percent of its dry year demand under every scenario. Key assumptions included:
1708
Ontario Municipal Utilities Company Section 4
Water Supply Assessment for West Haven Specific Plan Amendment Groundwater Analysis 60 • Reliance on assurances provided by MWD in its 2020 UWMP that it could meet 100 percent of projected supplemental full-service water supply demands through 2040;
• Implementation of MWD’s Chino Basin DYY Storage Program consistent with the contractual shift obligations of the participating agencies of up to 33,000 AF in a twelve-month period; and
• Sustain per capita water use reductions of 20 percent.

IEUA concluded in its 2020 UWMP that the projected available water supply will meet projected water demand due to diversified water supply and water conservation measures. Based on IEUA water supply projections, there are sufficient water supplies to meet normal year water demands, single dry year and multiple dry year demands (IEUA 2020 UWMP, p. 7-7).

CWC section 10631(j) provides that urban water suppliers that rely upon a wholesale agency for a source of water, such as IEUA, may rely upon water supply information provided by the wholesale agency in fulfilling UWMP informational requirements.

IEUA’s independent analysis of contemporary regional water conditions in conjunction with MWD’s most recent report, provide additional and reliable assurances concerning the sufficiency of imported water supplies that comprise a portion of overall Chino Basin supply sufficiency.

The City’s participation in the DYY Storage Program described in Section 3, along with future water storage and recovery projects will drought-proof the Chino Basin and all other appropriative pool members from imported water shortages. This program is consistent with OBMP Program Element No. 9, “Develop and Implement Storage and Recovery Program.” Benefits to the Chino Basin associated with this program include the construction of facilities to enhance imported water deliveries and the production of water from the Chino Basin. Further demonstrating the sufficiency of Chino Basin groundwater is MWD’s DYY program to use the Chino Basin for dry year supply purposes, thus underscoring that sufficient Chino Basin groundwater is available during 1709
Ontario Municipal Utilities Company Section 4
Water Supply Assessment for West Haven Specific Plan Amendment Groundwater Analysis 61 dry years not only for local use by agencies such as the City but also in connection with MWD’s regional reliability programs.

The sufficiency of groundwater supplies available to OMUC is assured because of the OBMP programs overseen by the Chino Basin Watermaster and conducted under the auspices of continuing Court jurisdiction that specifically direct and assure the longterm production of water pursuant to the City’s legal rights to produce such water necessary to meet ultimate water demands.

Conclusion
The City’s total annual groundwater production has held relatively stable over the past 10 years at roughly 20,000 AFY (OMUC 2020 UWMP, p. 6-3). Production capacity meets current demands and is projected to increase to meet ultimate demand. The current (FY 20/21) water supply utilized by the City totals approximately 33,969 AFY (potable) and 8,556.74 AFY (recycled water) (Table 3-2). Currently, the City’s water rights in the Chino Basin as recorded by the Chino Basin Watermaster total approximately 36,026 AF (Annual Production Rights for Non-Ag Pool plus Appropriative Pool), with an additional 96,992.4 AF in storage (Table 4-1). Although annual fluctuations will occur, the City’s rights are projected to increase over the next 20 years due to more land use conversions and credits from recharge.

The water supplies available to OMUC currently meet and exceed citywide water demands. Groundwater production by OMUC is currently less than their existing rights and within their production capacity. Regardless, OMUC has the means and right to exceed their groundwater allocation in the Chino Basin when required to meet demand pursuant to the Judgment. Further, OMUC has rights to water held in storage that would supply all City demands for more than two years. In addition to groundwater, OMUC can supply water to the Project purchased from the WFA that is within their existing entitlements and capacities.

1711
Ontario Municipal Utilities Company Section 5
Water Supply Assessment for West Haven Specific Plan Amendment Primary Issue for Assessment 63 The lead agency is expected to review the WSA and decide whether additional water supply information is needed for its consideration of the proposed Project.

5.1 Findings
Whereas:

1. The City of Ontario Municipal Utilities Company (OMUC) has been identified as the water supplier for the proposed West Haven Specific Plan Amendment (Project). The proposed Project will change the maximum allowable density of two existing planning areas to allow up to 389 additional units.

2. A previous WSA/WV was prepared in 2004 for the 8,200-acre New Model Colony (now called Ontario Ranch) that includes the Project site; however, it is no longer valid.

3. The estimated potable water demand for the additional dwelling units proposed by the Project is 109 AFY and the recycled water demand is 4 AFY for a total demand of 113 AFY.

4. The estimated water demand for the entire West Haven Specific Plan as currently proposed with the Project has a potable water demand of 477 AFY and recycled water demand of 190 AFY for a total of 667 AFY.

5. The City’s 2020 Water Master Plan included in its projections the water demand of the currently approved West Haven Specific Plan which this report estimates as 372 AFY of potable water and 186 AFY of recycled water for a total demand of 558 AFY. The water demand projections in the 2020 UWMP are based on the water demand projections in the 2020 Water Master Plan.

6. The increased water demand resulting from the additional units proposed by the Project was not accounted for by the 2020 UWMP dated July 2021 and adopted by the Ontario City Council by Resolution 2021-059 on June 15, 2021 (Appendix A).
1712
Ontario Municipal Utilities Company Section 5
Water Supply Assessment for West Haven Specific Plan Amendment Primary Issue for Assessment 64 7. OMUC has an Annual Production Right of 28,576.9 AF currently in the Chino Groundwater Basin as a member of the Appropriative Pool, as well as groundwater storage accounts that total 96,992.4 AF (Table 4-1). The water supply production capacity from City wells is currently 62,269 AFY,12 which is projected to increase to 110,337 AFY to meet demand (Table 3-4 and 3-5).

OMUC produced 17,171.1 AF of groundwater in FY 20/21 (Table 3-2).

8. In addition to Chino Basin production rights, OMUC holds shareholder entitlements to potable water from SAWCo in the amount of 600 AFY, and capacity rights to imported water from the WFA in the amount of approximately 28,000 AFY. OMUC also has capacity rights to potable water from the CDA in the amount of 8,533 AFY (Table 3-2 and 3-4). In FY 20/21, OMUC purchased 500 AF from SAWCo, 5,851 AF from WFA, and 7,337 AF from CDA (Table 3-2).

9. OMUC is entitled to the recycled water generated by IEUA from the City’s annual share of sewer flows. In FY 20/21, the City delivered 12,854 AF to IEUA wastewater treatment plants, of which 8,556.74 AF was put to non-potable direct recycled water use (Table 3-2).

10.As of FY 20/21, citywide potable and recycled water demands were 33,969 AF and 8,556.74 AF, respectively (Table 2-2); ultimate potable and recycled water demands are projected to be 57,609 AFY and 16,059 AFY, respectively (Table 2- 3).

11.The current production capacities are greater than needed to meet the average day demands under citywide buildout conditions. Additional wells are planned to supply the anticipated ultimate maximum day demand.

12.OMUC has forecasted excess water supplies will be available to meet citywide demand during single-dry and multiple dry water years over the next 20 years (Table 3-9 and Table 3-10).
12 Assuming wells operate 24 hours per day for 365 days per year. 1713
Ontario Municipal Utilities Company Section 5
Water Supply Assessment for West Haven Specific Plan Amendment Primary Issue for Assessment 65 13.Water demands for agricultural land uses in Ontario Ranch are planned to reduce to zero by 2040 with land use conversions and water demands for industrial uses in Ontario Ranch, which may include some manufacturing are expected to increase and partly replace former agricultural uses.

14.Based on the evidence provided herein, the total projected potable and recycled water supplies available to the OMUC during normal, single dry, and multiple dry water years over a 20-year projection will be sufficient to meet the projected water demand associated with the additional units of the proposed Project in addition to the water supplier’s existing and planned future uses, including agricultural and manufacturing uses. State mandated conservation efforts will reduce demand in the future.

1.1 Introduction
Senate Bill 221 (SB 221) was enacted in 2001 and became effective as of January 1, 2002. SB 221 establishes the relationship between the Water Supply Assessment (WSA) prepared for a project pursuant to Senate Bill 610 (SB 610), and the project approval under the Subdivision Map Act. SB 221 amends Section 11010 of the Business and Professional Code, and amends Section 65867.5 to add Sections 66455.3 and 66473.7 to the California Government Code.

Pursuant to Government Code Section 66473.7, the public water supplier must provide a written verification of sufficient water supply (WV) prior to the approval of a tentative subdivision map, or a parcel map for which a tentative map was not required, or a development agreement for a subdivision of property of more than 500 dwelling units, except as specified, including the design of the subdivision or similar type of improvement.

1.2 Purpose
The purpose of the WV is to provide the legislative body of a city, county, or the designated advisory agency with written verification from the applicable public water supplier that a sufficient water supply is available, or, in addition, a specified finding is made by the local agency that sufficient water supplies are, or will be, available prior to completion of the project.

The WV shall be supported by substantial evidence, which may include relevant portions of an applicable Urban Water Management Plan (UWMP) or a WSA prepared per SB 610. Many of the requirements for SB 610 compliance will satisfy the requirements of SB 221. There are four factors to be considered in a WV which are not 1724
Ontario Municipal Utilities Company
Written Verification for West Haven Specific Plan Amendment 2 required in a WSA as specified by Government Code Section 66473.7. Those four factors, which are specifically addressed in this WV are as follows:

1. Historical water supplies for at least 20 years;

2. Urban Water Shortage Contingency Analysis prepared for the water supplier’s UWMP;

3. Supply reduction for “specific water use sector” per water supplier’s resolution, ordinance, or contract; and

4. Amount of water that can be reasonably relied upon from specific supply projects, subject to the determinations outlined in Government Code Section 66473.7.

1.3 Project Description and Water Demand
This WV has been prepared in conjunction with a WSA for West Haven Specific Plan Amendment (“Project”). The West Haven Specific Plan encompasses 202 gross acres within the City of Ontario’s 8,200-acre Ontario Ranch. Annexed in 1999, the presently agricultural Ontario Ranch is planned to be developed into residential, commercial, industrial, and public uses (UWMP, p. 3-1). The proposed Project will increase the maximum allowable number of dwelling units (du) and densities in two residential Planning Areas (PA): PA 1 and PA 3. The Project would increase the number of allowable units by 278 units in PA 1 and the corresponding net density would increase from 6.78 du/acre to 17.68 du/acre (see WSA Figure 4 – Proposed Land Use Plan).

The total number of allowable units would increase by 111 units in PA 3 and the corresponding net density would increase from 4.86 du/acre to 10.72 du/acre. With these changes, the total number of allowable units in the West Haven Specific Plan would increase from 753 units to 1,142 units (SPA, p. 3-3). 1725
Ontario Municipal Utilities Company
Written Verification for West Haven Specific Plan Amendment 3 The City of Ontario Municipal Utilities Company (OMUC)1 is the water supplier for the Project and for the City. OMUC commissioned a WSA and WV from Albert A. Webb Associates (WEBB) on March 23, 2022. The purpose of preparing this WV for the Project is to preclude the need for individual “Written Verification” letters being prepared for the individual residential development projects that will qualify for a WV within the Project area. SB 221 applies to the Project because there will be residential subdivisions that may have more than 500 units which exceed the criteria set in section 66473.7(a) of 500 units.

The key question for this WV to address per SB 221 is whether the water supplier is able to provide a sufficient water supply based upon an analysis as to whether water supplies available during normal, single-dry, and multiple-dry years within a 20-year projection will meet the projected demand associated with the proposed subdivision(s), in addition to existing and planned future uses, including, but not limited to, agriculture and industrial uses (DWR 2003).

1.4 Verification of Sufficient Water Supply
A detailed evaluation of OMUC’s water supply was performed under the attached WSA for the Project. Attached to the WSA is the adopted City of Ontario 2020 UWMP which addresses normal, single dry, and multiple dry year conditions over the 20-year period from 2020 through 2040 (WSA Appendix A). The 2020 UWMP determined that sufficient water supply exists to support the demands of the OMUC service area. The WSA determined that the water demand of the Project is greater than the water demand for the same site that was assumed in the 2020 UWMP; therefore, the increased demand was not accounted for in the 2020 UWMP. However, the WSA concludes that sufficient water supply exists to support the Project. 1 OMUC is a department of the City of Ontario and the terms may be used interchangeably herein. 1726
Ontario Municipal Utilities Company
Written Verification for West Haven Specific Plan Amendment 4 20-Year Water Supply Availability
OMUC has been able to meet all water demands with its available water supplies for the past 20 years. Table 3-2 of the attached WSA shows the recorded water supplies from 2000-2020 that were utilized to meet the demand within OMUC’s service area. A supply source that is available to OMUC that is not included in Table 3-2 are the groundwater storage accounts to which OMUC has rights to store water in the Chino Basin. As of FY 20/21, the City has approximately 96,992.4 AF held in storage (CBWM, pp. 11.1, 12.1).

Urban Water Shortage Contingency Analysis (Plan)
The urban water shortage contingency analysis (Water Shortage Contingency Plan [WSCP]) prepared for the most recent UWMP is contained within Chapter 8 of Ontario’s 2020 UWMP (Appendix A). The WSCP is based on a draft Water Conservation Plan located in Appendix N of the 2020 UWMP that is an update of the City’s Ordinance No. 3027. The WSCP includes stages of action, prohibitions on end uses, penalties and enforcement measures, determination of water shortage reductions, revenue and expenditure impacts, and catastrophic supply interruption.

The 2020 WSCP and draft Water Conservation Plan are consistent with the stringent emergency conservation regulations mandated by the State Water Resources Control Board in response to statewide drought conditions. The purpose of the ordinance and the Water Conservation Plan are to minimize the potential for a water shortage through the practice of water conservation, and to minimize the effect of a shortage of water supplies on the water customers of the City. In addition, it is the intent of the ordinance and the Water Conservation Plan to adopt provisions that will significantly reduce the inefficient consumption of water, thereby extending the available water resources necessary for domestic, sanitation, and fire protection of the community to the greatest extent possible (Municipal Code Sec. 6-8.21).

The 2020 WSCP and draft Water Conservation Plan describe the methods to respond to a water supply shortage of more than 50 percent. Six stages of conservation are 1727
Ontario Municipal Utilities Company
Written Verification for West Haven Specific Plan Amendment 5 described (Stages 1-6) with increasing conservation requirements and penalties depending on the severity of the shortage (UWMP, p. 8-8).

Supply Reduction for Specific Water Use Sector
OMUC’s 2020 WSCP and draft Water Conservation Plan establish voluntary and mandatory water conservation requirements which shall take effect upon implementation. During a water shortage crisis, certain mandatory restrictions on water use will be imposed on the public. The voluntary water use prohibitions apply at all times. Stage 1 to 6 prohibitions will be progressively implemented according to the severity of the water crisis (OMUC 2020 UWMP, Appendix N). The restrictions and prohibitions on end users that correspond to Stages 1 to 6 are outlined in Table 8-2 of the City’s 2020 UWMP (p. 8-3). OMUC does not have a water supply allocation plan.

No single water use sector is identified in the 2020 WSCP or draft Water Conservation Plan for supply reductions in the event of a water shortage crisis.

Amount of Water That Can Be Reasonably Relied Upon from Specific Supply Project(s)
This requirement of the WV pertains to projected water supplies that the water supplier can reasonably rely on that are not currently available to the public water system. All projected water supplies are currently available to OMUC but may not be fully utilized to date. Descriptions of the supplies available to OMUC are in Section 3 of the attached WSA.

1.5 Substantial Evidence of Verification of Sufficient Water Supply This WV does not rely on projected water supplies that are not currently available to OMUC. The water supplies that OMUC will continue to rely on that are projected to be sufficient to meet current and future needs are described in Section 3 of the attached WSA. Because projected supply sources are currently available to OMUC, supporting information pursuant to Gov. Code section 66473.7 is not provided herein. This would include written contracts or other proof of valid rights to supplies under development, an adopted capital outlay program to finance delivery of supplies under development, 1728
Ontario Municipal Utilities Company
Written Verification for West Haven Specific Plan Amendment 6 permits to construct supply infrastructure for supplies under development, and regulatory approvals for conveyance or delivery of supplies under development.

Copies of the rights, contracts, and other entitlements to water supplies available to OMUC are provided in the appendices to the attached WSA.

1.6 Impacts to Agricultural and Industrial Users
Gov. Code section 66473.7 requires this WV to contain a description of reasonably foreseeable impacts of the proposed subdivision on the availability of water resources for agricultural and industrial uses within the water supplier’s service area that are not currently receiving water from the water supplier but are utilizing the same sources of water. Water used by industrial and agricultural users that is not provided to them by OMUC would come from their private wells to access the Chino Groundwater Basin, which OMUC also utilizes. Adverse impacts to such entities as a result of the Project is not anticipated because the Chino Basin is an adjudicated basin with a court appointed Watermaster who monitors and enforces the provisions of the 1978 Judgment and subsequent orders of the court. As discussed in Section 4 of the attached WSA, the Watermaster develops and implements an Optimum Basin Management Program to sustainably manage the basin for all users.

In regard to agricultural use, the original (2007) West Haven Specific Plan Draft EIR states: “The Project site lies within the NMC area commonly referred to as the “Ag Preserve.” The Ag Preserve was the last significant underdeveloped area in the San Bernardino Valley. In 1993, the County of San Bernardino Board of Supervisors voted to consider dissolving the Ag Preserve status, allowing the transition of the site’s historically agricultural land use practices to other locations and, ultimately the development of this area in an urban setting. (URS, p. 2-1) “Following the City’s January 7, 1998 NMC GPA adoption, the Project site was designated in the General Plan as Low Density Residential and Commercial Neighborhood Center, and was zoned Specific Plan. Historically, the Project site and 1729
Ontario Municipal Utilities Company
Written Verification for West Haven Specific Plan Amendment 7 surrounding area primarily functioned agriculturally, consisting of dairy farm operations, row crops production and some vineyard use.” (URS, p. 3-2) The Ontario General Plan Amendment for the New Model Colony [Ontario Ranch] (1998) projects a nearly 100 percent conversion of existing agricultural land to nonagricultural uses, except for approximately 200 acres of land that are owned by the County of San Bernardino and managed by the Southern California Land Foundation.

This does not include the West Haven Specific Plan. As planned for by the City and discussed in the attached WSA, agricultural properties are projected to decrease with the conversion of Ontario Ranch to non-agricultural activities (WSA Figures 5 and 6).

Table 3-7 of the attached WSA also forecasts declines in recycled water use by agriculture, reaching zero use by 2040. As of 2020, there are 20 agricultural recycled water irrigation sites (2020 Annual Report to DDW). The proposed subdivision is not anticipated to have adverse impacts on the shared water supply source because the 2020 UWMP has incorporated planned future declines in agricultural use in the water demand projections, which includes declines in private wells and conversion to OMUC supplies.

In regard to industrial uses, they are currently (2020) the third most common land use type in the City (after Agricultural, Multi-Use at 21.2 percent, and Residential at 19.3 percent), making up approximately 5,498 acres or 17.3 percent of the total (AKM 2020, p. 2-5). The ultimate citywide land use plan (The Ontario Plan 2010) plans for an increase of business parks and industrial uses to cover about 7,818 acres or 24.6 percent at buildout (AKM 2020, p. 2-7). Further, the 2020 UWMP citywide projections in the attached WSA show potable water use by industrial uses increasing from 2,078 AFY in 2020 (WSA Table 2-2) to 3,728 AFY in 2040 (WSA Table 2-3) and industrial use of recycled water is projected to increase from 986 AFY in 2020 to 3,680 AFY in 2045 (WSA Table 3-7). As of 2020, there are three industrial recycled water sites (2020 Annual Report to DDW). The proposed subdivision is not anticipated to have adverse impacts on the shared water supply source because the 2020 UWMP water demand 1730
Ontario Municipal Utilities Company
Written Verification for West Haven Specific Plan Amendment 8 projections have accounted for future increases in potable and recycled water use by industrial uses, in addition to other uses.

For each acre of agricultural land that converts to urban use, the initial Safe Yield of the appropriative pool member serving the converted land is increased by 2 acre-feet. In addition, properties that were on private wells are expected to connect to OMUC infrastructure. Therefore, OMUC’s share of the Safe Yield will continue to increase as Ontario Ranch develops, concurrent with a decline in private wells in the Chino Basin.

1.7 Priority to Proposed Lower Income Housing Projects
Pursuant to Gov. Code section 65589.7, the determinations made by the WV shall be consistent with the obligation of a public water system to grant a priority for the provision of available and future water resources or services to proposed housing developments that help meet the City’s (or County’s) share of the regional housing needs for lower income households.

The 2020 UWMP states that the City has considered the demographic factors of severely low-income earners, single-parent families, large families, seniors, people with disabilities, and homeless persons “which can affect the City’s water management planning” (p. 3-7). Further, the 2020 UWMP indicates that lower income residential demands are included in water use projections (ibid, p. 4-12).

The following excerpt from the “City of Ontario New Model Colony Specific Plan Policy Matrix” located in the Draft West Haven Specific Plan Amendment describes the Project’s consistency with applicable policies from the City General Plan Housing Element (p. A-35):

1.8 Verification That Relies on Groundwater
Law
Gov. Code Sec. 66473.7 (h)
Where a water supply for a proposed subdivision includes groundwater, the public water system serving the proposed subdivision shall evaluate, based on substantial evidence, the extent to which it or the landowner has the right to extract the additional groundwater needed to supply the proposed subdivision.

Nothing in this subdivision is intended to modify state law with regard to groundwater rights.

Section 4 of the attached WSA describes OMUC’s legal right to extract groundwater from the Chino Basin.

1.9 Finding of Sufficient Water Supply
As depicted in Table 3-2 and Table 3-3 of the attached WSA, the City’s 2020 and ultimate total water supply (39,921 AFY in FY 19/20 and 73,668 AFY in 2045, respectively) are sufficient to meet the existing and anticipated water demands from its 1732
Ontario Municipal Utilities Company
Written Verification for West Haven Specific Plan Amendment 10 service area including the proposed Project’s additional combined potable and recycled water demand of 113 AFY (WSA Table 2-5). Based on the analysis herein and the attached WSA, OMUC finds that “sufficient water supply” is available to support the projected subdivisions within the West Haven Specific Plan Amendment area as it is currently described herein.

NOW, THEREFORE, IT IS HEREBY FOUND, DETERMINED, AND RESOLVED by the City Council of the City of Ontario, as follows:
1738
SECTION 1. Housing Element Compliance. Pursuant to the requirements of California Government Code Chapter 3, Article 10.6, commencing with Section 65580, as the decision-making body for the Project, the City Council finds that based upon the facts and information contained in the Application and supporting documentation, at the time of Project implementation, the project is consistent with the Housing Element of the Policy Plan (General Plan) component of The Ontario Plan, as the project site is not one of the properties in the Housing Element Sites Inventory contained in Tables B-1 and B-2 of the Housing Element Technical Report.

SECTION 2. Airport Land Use Compatibility Plan ("ALUCP") Compliance.

The California State Aeronautics Act (Public Utilities Code Section 21670 et seq.) requires that an Airport Land Use Compatibility Plan be prepared for all public use airports in the State; and requires that local land use plans and individual development proposals must be consistent with the policies set forth in the adopted Airport Land Use Compatibility Plan.

On April 19, 2011, the City Council of the City of Ontario approved and adopted the Ontario International Airport Land use Compatibility Plan, establishing the Airport Influence Area for Ontario International Airport, which encompasses lands within parts of San Bernardino, Riverside, and Los Angeles Counties, and limits future land uses and development within the Airport Influence Area, as they relate to noise, safety, airspace protection, and overflight impacts of current and future airport activity. As the decisionmaking body for the Project, the City Council has reviewed and considered the facts and information contained in the Application and supporting documentation against the ONT ALUCP compatibility factors, including [1] Safety Criteria (ONT ALUCP Table 2-2) and Safety Zones (ONT ALUCP Map 2-2), [2] Noise Criteria (ONT ALUCP Table 2-3) and Noise Impact Zones (ONT ALUCP Map 2-3), [3] Airspace protection Zones (ONT ALUCP Map 2-4), and [4] Overflight Notification Zones (ONT ALUCP Map 2-5). As a result, the City Council, therefore, finds and determines that the Project, when implemented in conjunction with the conditions of approval, will be consistent with the policies and criteria set forth within the ONT ALUCP; and
SECTION 3. Concluding Facts and Reasons. Based upon the substantial evidence presented to the City Council during the above-referenced hearing, and upon the specific findings set forth in Sections 1 and 2, above, the City Council hereby concludes as follows:
(1) The proposed Specific Plan, or amendment thereto, is consistent with the goals, policies, plans and exhibits of the Vision, Policy Plan (General Plan), and City Council Priorities components of The Ontario Plan. The proposed Specific Plan Amendment is consistent with the Vision, Policy Plan (General Plan), and City Council Priorities components of The Ontario Plan 2050, in that the Specific Plan Amendment contributes towards the legislative framework for the implementation of The Ontario Plan components, guiding growth and development within the Project area to achieve optimum results from the City’s physical, economic, environmental, and human resources. 1739
(2) The proposed Specific Plan, or amendment thereto, would not be detrimental to the public interest, health, safety, convenience, or general welfare of the City. The development standards and guidelines established by the proposed Specific Plan Amendment have been created with the intent to safeguard and further the public interest, health, safety, convenience, and/or general welfare, and to ensure that the purposes of The Ontario Plan 2050 and the proposed Specific Plan Amendment, are maintained.
(3) In the case of an application affecting specific properties, the proposed Specific Plan, or amendment thereto, will not adversely affect the harmonious relationship with adjacent properties and land uses. The location of the proposed Specific Plan Amendment, and the proposed conditions under which future developments will be constructed and maintained, is consistent with the Policy Plan component of The Ontario Plan 2050 and the City’s Development Plan, and, therefore, will not adversely affect the harmonious relationship with adjacent properties and land uses. (4) In the case of an application affecting specific properties, the subject site is physically suitable, including, but not limited to, parcel size, shape, access, and availability of utilities, for the request and anticipated development. The proposed Specific Plan Amendment has been reviewed by all City departments, which have established that the project site is physically suitable for the anticipated development in terms of parcel size, shape, and availability of utilities.

SECTION 4. City Council Action. Based upon the findings and conclusions set forth in Sections 1 through 3, above, the City Council hereby APPROVES the herein described Application.

SECTION 5. Indemnification. The Applicant shall agree to defend, indemnify and hold harmless, the City of Ontario or its agents, officers, and employees from any claim, action or proceeding against the City of Ontario or its agents, officers or employees to attack, set aside, void, or annul this approval. The City of Ontario shall promptly notify the applicant of any such claim, action, or proceeding, and the City of Ontario shall cooperate fully in the defense.

SECTION 6. Custodian of Records. The documents and materials that constitute the record of proceedings on which these findings have been based are located at the City of Ontario City Hall, 303 East "B" Street, Ontario, California 91764. The custodian for these records is the City Clerk of the City of Ontario.

The City Clerk of the City of Ontario shall certify as to the adoption of this Resolution.

WEST HAVEN SPECIFIC PLAN 1-1
SECTION 1

INTRODUCTION

1.1 Specific Plan Purpose
The West Haven Specific Plan (Project, Project Site)
provides land use concept, design guidelines, and
development regulations for an integrated mixed
use project that includes residential neighborhoods,
a neighborhood center commercial use area, open
space and recreational uses. The West Haven
Specific Plan document defines the methods and
requirements for development of the project to ensure
that The Ontario Plan (TOP) City of Ontario, New
Model Colony (NMC) Ontario Ranch General Plan
Amendment (GPA) requirements are implemented.

The West Haven Specific Plan, when adopted,
will serve as a legal document, which defines and
implements the Land Use Designations of:
• Residential Medium Density
• Residential Low Medium Density
• Residential Low Density
• Neighborhood Center
• Elementary School
• Neighborhood Park
It will serve as the zoning for the Project Site. The
West Haven Specific Plan serves as a “blueprint” for
development by establishing the distribution of land
use and the criteria for development of each land
use as set forth herein. The West Haven Specific
Plan establishes the development requirements and
guidelines to be applied to each land use contained
within the Project Site area.

Tentative Tract(s) / Parcel Map(s) and/or Development
Plans (C.U.P., Plot Plans, etc.) will be prepared and
submitted to the City pursuant to the applicable
provisions of the State of California Subdivision
Map Act (Government Code Section 66410 through
66499), the City of Ontario Subdivision Ordinance and
be consistent with the applicable provisions contained
within the West Haven Specific Plan.TheSubdivision
Maps/Development Plans will be submitted for City
review and approval prior to development of the
Project Site.

1.2 Authority for the Specific Plan
State of California Code, Title 7, Division 1, Chapter
3, Article 8, Section 65450-57 grants authority to cities to adopt Specific Plans for purposes of implementing
the goals and policies of their General Plans. The
Government Code states that Specific Plans may
be adopted either by resolution or by ordinance and
may be amended as often as deemed necessary by the
legislative body. No Specific Plan may be adopted or
amended unless the proposed plan or amendment is
consistent with the General Plan. The Government
Code sets forth the minimum requirements and review
procedures for Specific Plans, including provisions of
a Land Use Plan, Infrastructure and Public Services
Plan, criteria and standards for development and
implementation measures. The Government Code
also states that Specific Plans may address any other
subjects which, in the judgment of the City, are
necessary or desirable for implementation of the TOP
General Plan.

Following adoption by the City of Ontario of the
New Model Colony (NMC) Ontario Ranch General
Plan Amendment (GPA), the Project Site was
pre-zoned as SP/AG (Specific Plan/ Agricultural
Preserve). The zoning designation of “SP” requires
the project area to be developed with a Specific
Plan to carry out the objectives of the New Model
Colony Ontario Ranch General Plan land uses.

TheWest Haven Specific Plan is designed to meet the
requirements of the State of California Government
Code and The City of Ontario's NMC Ontario
Ranch General Plan. The City of Ontario will
adopt the West Haven Specific Plan by resolution
thereby establishing the zoning regulations for the
development of the Project Site. The requirements
of the Specific Plan shall take precedence over the
City of Ontario Development Code. In instances
where the West Haven Specific Plan does not
address specific zoning requirements, development
standards or guidelines, the City of Ontario
Development Code shall prevail.

The West Haven Specific Plan is the major
component in the City’s entitlement process that
will result in the future development of the master
planned community. The components of the
development entitlement process for the Project
are discussed within the West Haven Specific Plan
document.

1.3 Background
The West Haven Specific Plan mixed residential
and commercial community is located in the City
of Ontario, in what was formerly the approximate
8,200-acre City of Ontario Sphere of Influence (SOI).

Refer to Exhibit 1-1, “Regional Context Map” and
Exhibit 1-2, “Vicinity Map.” On January 7, 1998,
the City of Ontario adopted the New Model Colony
General Plan Amendment (GPA) setting forth a
comprehensive strategy for the future development of
the SOI. The SOI was annexed into the City of Ontario
in November 1999, and is now was referred to as the
New Model Colony (NMC), but since has been
renamed Ontario Ranch. The regional location of
the West Haven Specific Plan area is illustrated in
The West Haven Specific Plan is proposed as a
master planned, single-family detached and attached
residential and Neighborhood Center Commercial
development with approximately 202 total gross
acres.

the West Haven Specific Plan area is illustrated in
Exhibit 1-1, “Regional Context Map.” The West
Haven Specific Plan location is illustrated in Exhibit
1-2, “Vicinity Map.”
The West Haven Specific Plan is proposed as a
master planned, single-family detached and attached
residential and Neighborhood Center Commercial
development with approximately 202 total gross
acres. The project area consists of ten (10) parcels with six (6) separate ownerships, and is being developed by four (4) separate developers at this
time, Armada LLC, Richland Communities, SC
Ontario Development Corporation and Stratham
Properties, Inc. Approximately 11.7 gross acres will
be developed in the future as Neighborhood Center
Commercial. Exhibit 1-3, “Existing Assessor’s
Parcels, Developers and Property Ownership” illustrates this information.

The West Haven Specific Plan consists of portions
of the New Model Colony Subareas 6 and 12, west
of Haven Avenue. The City of Ontario has indicated that the NMC Land Use Plan designations within Subareas 6 and 12 for the area west of Haven
Avenue would allow for a total of 753 dwelling

On January 7,1998, the Ontario City Council
adopted the Sphere of Influence General Plan
Amendment for the 8,069-acre area known as the
“The New Model Colony” (NMC). On November
30, 1999, the area was annexed into the City of
Ontario. The New Model Colony General Plan
provided the framework to create a high-quality
environment where residents will live, work
and play. The area was divided into 30 subareas,

WEST HAVEN SPECIFIC PLAN 1-3
each requiring the preparation of a specific plan
reflecting the unique goals and qualities of each
area. In this way, each subarea could be part of
the overall New Model Colony but retain a sense
of individuality.

Following the adoption of the New Model Colony
General Plan, the Project Site was pre-zoned as
SP/AG (Specific Plan/Agricultural Preserve). The
zoning designation of “SP” requires the project
area to be developed with a Specific Plan to carry
out the objectives of the New Model Colony
General Plan land uses.

On January 26th, 2010, the City of Ontario
adopted The Ontario Plan (TOP) which serves as
the City’s new business plan and includes a longterm Vision and a principle based Policy Plan (General Plan). The City’s Policy Plan, which
acts as the City’s General Plan, designates (Policy
Plan Exhibit LU-1 - Land Use Plan) the project
site for development of Low Density Residential
(2.1-5.0 dwelling units per acre), Low Medium
Residential (5.1-11.0 dwelling units per acre),
Medium Density Residential (11.1-25.0 dwelling
units per acre), Neighborhood Commercial,
Public Schools, and Open Space- Parkland, as
illustrated on Exhibit 1-4, “Policy Plan Land Use
Map.”

units as illustrated on Exhibit 1-4, “Subareas 6 and
12 Residential Allocation Exhibit” and Table 1-1,
“Residential Density.” Please refer to Section 2.2.6,
“Existing General Plan Land Use and Zoning” for
more detailed information.

1.4 Project Description
The West Haven Specific Plan is a comprehensive
plan for the development of a mixed-use community with Planned Residential Sites that will accommodate 753 dwelling units on approximately 146.9 residential acres; Neighborhood Center on approximately 11.7 gross acres, an elementary school site on 10 net acres, a five (5) net acre Neighborhood Park,
and approximately 10 acres of paseos and pocket
parks within the Specific Plan community and the
adjacent utility easements. The combination of these
master planned uses truly makes this a mixed-use
development.

The City of Ontario NMC General Plan Amendment
establishes a bike route system connecting the West
Haven Specific Plan to planned bike routes within
the remainder of the New Model Colony. A Class I
Bike Path is designated to be included within the improved right-of-way of Haven Avenue and within the north-south Edison Easement and fee owned properpROJect site intErStatE

WEST HAVEN SPECIFIC PLAN 1-7
The City of Ontario NMC General Plan Amendment
Ontario Plan establishes a bike route system
connecting the West Haven Specific Plan to planned
bike routes within the remainder of the New Model
ColonyOntario Ranch. A Class I Bike Path is designated
to be included within the improved right-of-way of
Haven Avenue and within the north-south Edison
Easement and fee owned property that are within and
adjacent to the westerly boundary of the Project Site.

The bike paths will eventually connect to the planned
City of Ontario bike route system consistent with the
NMC General Plan The Ontario Plan.

A primary landscape entry monumentation area is to
be constructed at the intersection of Riverside Drive
and Haven Avenue (southwesterly corner).

Secondary landscaped entry monumentation will be
constructed at the intersection of Haven and Chino
Avenues at both northwesterly and southwesterly
corners.

1.5 West Haven Specific Plan Goals
and Objectives
The West Haven Specific Plan proposes to meet the
following objectives and addresses the following
issues.
• To provide an integrated quality mixed-use
Planned Residential and Neighborhood Center
community of appropriate density and lot sizes,
supported by landscaped open spaces, landscaped
pedestrian and bike paseos, elementary school,
Neighborhood Park and recreational uses.
• To provide six (6) distinct yet blended residential
neighborhoods with a variety of housing types,
including single-family detached, courtyard, and
attached/detached alley loaded residences, on
lot sizes ranging from 2,800 square feet to 6,000
square feet.
• To provide for adequate planning, financing and
implementation mechanisms for infrastructure
and community facilities to serve the master
planned community.
• To establish appropriate relationships with
existing adjacent commercial and residential land
uses.
• To integrate existing and proposed commercial
areas into the community fabric via pedestrian
links and walkways.
• To provide for a circulation network which
promotes pedestrian walkways and bicycle
activity as alternative modes of travel while also
providing for safe and efficient movement of
automobile travel through the Project Site. This
includes:
a. A major paseo linking all areas of the site
and connecting recreation spaces within the
community. The paseo network will also link
to the NMC’s Ontario Ranch master planned
residential paseo system and to regional
destinations.

1.6 Relationship of the Specific Plan
to the City of Ontario General Plan
Please refer to Appendix I, “General Plan
Consistency”.

1.7 CEQA Compliance
Prior to the adoption of the GPA for the NMC
TOP, the City of Ontario certified a program
level Environmental Impact Report identifying
environmental impacts associated with the activities
proposed for the NMC Ontario Ranch and established
mitigation measures for future activities. A project
level Environmental Impact Report (EIR), prepared
by the City of Ontario for the West Haven
Specific Plan, in accordance with the California
Environmental Quality Act (CEQA) and City
requirements, will provide a more detailed analysis of
potential environmental impacts associated with the
specific development project proposed for the Project
Site. The EIR prepared for the West Haven Specific
Plan should address the potential environmental
factors associated with the project and recommend
mitigation measures to reduce impacts to a less than
significant level. The EIR will be prepared to fulfill
the requirement for environmental determinations
for all subsequent discretionary and ministerial
applications for development within the West Haven
Specific Plan. The City of Ontario will prepare a
Fiscal Impact Analysis to accompany the EIR for the
Specific Plan to determine the project’s fiscal impact.

1.8 Severance
If any regulation, condition, program or portion
of the West Haven Specific Plan is held invalid
or unenforceable, such portions shall be deemed
separate, distinct and independent provisions and
the invalidity of such portions or provisions shall not affect the validity and enforceability of the remaining portions and provisions therein.

SECTION 2

EXISTING PROJECT SITE

CONDITIONS

2.1 Site History
The Project Site is part of an 8,200 acre area annexed
into the City of Ontario on November 30, 1999. The
approximate 202 acre West Haven Specific Plan area
has historically been used for agricultural purposes.

Agricultural activities have included dairy farming,
vineyards and row crop production.

2.2 Existing Project Site Conditions
The Project Site is gently sloping approximately 2%
to the southwest with approximately 50 feet of fall
diagonally from the northeasterly corner to the
southwesterly corner. Refer to Exhibit 2-1, “Existing
West Haven Topography,” which details the terrain.

Detention basins are found throughout the Project Site.

These are used to detain dairy rinse wastewater and rain runoff.

2.2.1 Existing Land Use
Dairy farm operations are found throughout the Project
Site. Ancillary uses such as feed lots, feed storage, dairy cattle pens, feed crop growing areas and residences
associated with dairy operations are found within
the area. The portion adjacent to Turner Avenue was
utilized for vineyard use but is now vacant. There is
an existing horticulture nursery located approximately
1,245 feet south of the intersection of Haven Avenue
and Riverside Drive.

Surrounding land uses are as follows:

North: Single Family Residential and Par 3 Golf
Course
South: Dairy Farming and Single Family
Residences
East: Dairy Farming, Crops, Nursery and
Residences Undeveloped Land and Residential
West: Single Family Residences, and Utility
Corridor and Nursery.

Existing on-site and surrounding land uses are
depicted on Exhibit 2-2, “Existing On-site and
Surrounding Land Uses.”

2.2.2 Existing Environmental Conditions

2.2.2(a) Geology and Soils
The Program EIR prepared for the City’s GPA for the
NMC Ontario Ranch identifies the approximately
8,200 acre NMC Ontario Ranch area, including the
Project Site, as underlain by Pleisocene age (older
than 12,000 years) and Holocene age (less than 12,000
years old) alluvial deposits. The youngest superficial
deposit is eolian sands (Qhs), comprising wind-blown
sands having fine to medium-sized grains. These
loose sands form sheets and low-dune deposits that
have been stabilized by vegetation. These deposits
are exposed in the eastern portion of the NMC area,
including the Project Site, and extend westward to an
area defined generally by a diagonal line extending
from Harrison Avenue, within Riverside County, on
the south to Vineyard Avenue on the north.

It is expected that most of these materials will be uncemented and subject to consolidation when saturated under structural loads. Erosion potential is considered high. Foundation and backfill suitability should be
satisfactory with proper over-excavation, mixing with
a finer-grained binder material and compaction.

Soils reports were prepared for several properties
within the West Haven Specific Plan confirming soils
types. These reports are in the Appendix as follows:

Agricultural activities have included dairy farming,
vineyards and row crop production.

2.2 Existing Project Site Conditions
The Project Site is gently sloping approximately 2%
to the southwest with approximately 50 feet of fall
diagonally from the northeasterly corner to the southwesterly corner. Refer to Exhibit 2-1, “Existing West Haven Topography,” which details the terrain.

Detention basins are found throughout the Project
Site. These are used to detain dairy rinse wastewater
and rain runoff.

2.2.1 Existing Land Use
Dairy farm operations are found throughout the
Project Site. Ancillary uses such as feed lots, feed
storage, dairy cattle pens, feed crop growing areas
and residences associated with dairy operations are
found within the area. The portion adjacent to Turner
Avenue was utilized for vineyard use but is now
vacant. There is an existing horticulture nursery located approximately 1,245 feet south of the intersection of Haven Avenue and Riverside Drive.

2.2.2 Existing Environmental Conditions

2.2.2(a) Geology and Soils
The Program EIR prepared for the City’s GPA for
the NMC identifies the approximately 8,200 acre
NMC area, including the Project Site, as underlain
by Pleisocene age (older than 12,000 years) and
Holocene age (less than 12,000 years old) alluvial deposits. The youngest surficial deposit is eolian sands (Qhs), comprising wind-blown sands having
fine to medium-sized grains. These loose sands form
sheets and low-dune deposits that have been stabilized by vegetation. These deposits are exposed in the eastern portion of the NMC area, including the
Project Site, and extend westward to an area defined
generally by a diagonal line extending from Harrison
Avenue, within Riverside County, on the south to
Vineyard Avenue on the north.

It is expected that most of these materials will be uncemented and subject to consolidation when saturated under structural loads. Erosion potential is considered high. Foundation and backfill suitability should be satisfactory with proper over-excavation, mixing
with a finer-grained binder material and compaction.

2.2.2(b) Seismicity
The Program EIR prepared for the City’s GPA for the
NMC identified numerous earthquake faults within
a 50 mile radius of the Project Site. Major mapped
faults include, but are not limited to, the Chino,
Whittier-North Elsinore and Cucamonga Faults. For
the “Maximum Probable Earthquake” (MPE), defined as the 100-year event normally considered in the design of non-critical structures, the values range from about 0.13 to 0.20 g (i.e., the unit force of gravity). In the design of certain critical or important facilities such as hospitals and dams, the “Maximum Credible Earthquake” (MCE) event is considered. For
the three faults, the MCE should yield an estimated
peak horizontal acceleration in the range of 0.33 to

0.52 g.

A zone of concentrated, relatively low-magnitude
seismicity extends to the southwest from the San
Jacinto fault zone (Rialto-Colton branch) along what
is referred to as an “inferred fault near Fontana.”
Where the “inferred fault” (Fontana trend) stops, this
zone of micro-seismicity continues in a southwesterly to westerly direction, terminating in the NMC Ontario Ranch area. It is expected that the MPE for
this fault structure could produce horizontal accelerations in the range of 0.3 to 0.5g. More distant faults are capable of larger earthquakes with a higher
probability of occurrence. The San Andreas Fault is
expected to generate a MCE event every 150 to 200
years, yielding a peak horizontal ground acceleration
of approximately 0.21 to 0.26 g.

In accordance with the “Uniform Building Code”
(UBC), the West Have Specific Plan area is located
within Seismic Zone No. 4. UBC procedures have
been designed to ensure that all subsequent development occurs in a safe manner relative to those known hazards.

Leighton and Associates, Inc. prepared a “DueDiligence Geotechnical Study” for Centex Homes on November 15, 2002 (See Appendix III, under separate cover). The study states; “The principle seismic hazard that could affect the site is ground shaking resulting from an earthquake occurring along several major active or potentially active faults in Southern
California.”Associated Soils Engineering, Inc.
prepared a “Due Diligence Review of Geotechnical
Data” for Centex Homes on April 21, 2004 (See
Appendix V, under separate cover). The study states;
“the subject project is not located within an AlquistPriolo Earthquake Fault Zone.” Additional seismicity information for the Project
Site is identified as part of the West Haven EIR.

2.2.2(c) Hydrology
Since most of the West Haven Specific Plan area has
been in agricultural use, only a limited portion of the Project Site is now covered with impervious surfaces.

Normal rainfall to the area is able to percolate through on-site soils and does not result in high volumes of
surface runoff, as typically associated with urban
areas. During periods of heavy rainfall, when ground
surfaces are saturated, surface runoff sheet flows in a south to southwesterly direction.

With the exception of major flood control channels
such as the Cucamonga Channel, intended primarily
to carry urban runoff, the existing storm drain system
throughout the NMC Ontario Ranch area is generally
unimproved and consists primarily of open earthen
swales along area roadways or curbed roadway
surfaces.

Ground waters within the NMC Ontario Ranch,
as a whole, contain high concentrations of salt
attributable to historic agricultural activities such as dairy farming. The high organic content of on-site
soils has contributed incrementally to the degradation
of surface and ground water quality. Removal of
the organic materials that constitute by-products of
those dairy operations, and compliance with National
Pollution Discharge Elimination System (NPDES)
and other storm water permit requirements; will
beneficially impact regional water quality.

Leighton and Associates, Inc. prepared a “DueDiligence Geotechnical Study” (See Appendix III, under separate cover). The study states, regarding
groundwater; “Groundwater was not encountered
during our field investigation to a maximum depth of
1773
SECTION 2 • Existing Project Site Conditions
WEST HAVEN SPECIFIC PLAN 2-5
10 feet below the ground surface.”
LOR Geotechnical Group, Inc. prepared the
“Engineering Geologic and Soils Foundations
Investigation” (See Appendix II, under separate
cover). The study states; “Groundwater was not
encountered in any of our exploratory trenches or borings which ranged in depth from 15 feet to 50.” LOR Geotechnical Group, Inc. prepared the “Phase I
Environmental Site Assessment” for JMS Properties
(See Appendix IV, under separate cover) and states
that; “The site lies within the Chino Groundwater
Basin. Significant portions of the basin have been affected by elevated concentrations of nitrate and total dissolved solids as a result of the long-term agricultural and dairy activities in the area. Pesticides are not a contaminant in the groundwater.”
Please see the Environmental Impact Report, as prepared for the West Haven Specific Plan, for further details.

2.2.2(d) Historic and Archeological
The Program EIR prepared for the City’s GPA for the
NMC Ontario Ranch identifies the approximately
8,200 acre NMC Ontario Ranch area as associated
with the northern extent of the Prado Basin and
includes portions of the historic Rancho Santa Ana
del Chino. The majority of known resources identified
within the NMC Ontario Ranch area can be associated
with the post-rancho period and the development of the
area as a late 19th century and early 20th century rural community.

Only a small portion of the overall study area has been systematically investigated for cultural resources.

Therefore, virtually nothing is known with respect to
the extent of prehistoric remains within the area. No
cultural resources have been specifically identified
with the study area. Therefore, there are no cumulative impacts identified at this time.

The Program EIR further states that the majority of the study area (90%) has not been formally investigated for the presence/absence of cultural resources. It is known that at least two pending historic archeological sites
and another twenty historic structural locations may be located within the study area. Until proven otherwise,
it must be presumed that the overall area is moderately sensitive for cultural resources.

Michael Brandman Associates prepared an
“Archeological Resource Evaluation and
Paleontological Records Search for the West Haven
Specific Plan Project, Sub area 6 (West of Haven)
and Subarea 12 (West of Haven), City of Ontario,
San Bernardino County, California” for the Stratham
Group, dated March 29, 2004 (refer to Appendix VI,
under separate cover). The study states; “Because
of the degradation of the topsoil after the dairies
had been built, the potential for impacts to cultural
resources is considered ‘low’. Cultural mitigationmonitoring is not recommended.” Please see the Environmental Impact Report, as prepared for the West Haven Specific Plan, for further details.

2.2.2(e) Biological
The Program EIR prepared for the City’s NMC TOP
General Plan Amendment states that the Sphere of
Influence is currently dominated by agricultural fields, dairy operations, pastures and croplands.

Remnants of native vegetation are virtually absent.

According to Küchler’s (1977) map of the potential natural vegetation of California, the Sphere of Influence area was historically dominated by coastal
sage scrub vegetation. Windrows are prevalent along
the internal roadways. Areas of intensive agricultural
industry such as feedlots and permanent cattle holding
pens are generally devoid of vegetation.

The Program EIR further states that the Ontario Sphere
of Influence area has been greatly altered from natural conditions, under the influence of intensive agriculture and dairy industry. Despite these continuing land use
practices, the Sphere of Influence area supports a
diversity of wildlife, especially that of birds. This
is due, in part, to the relatively level topography that contributes to the accumulation of standing water that
attracts numerous migratory birds.

Larry Munsey International was retained by JMS
Homes, LLC to conduct a presence/absence survey
for the Delhi Sands Flower-Loving Fly (DSF) on

Properties retained Larry Munsey International to
conduct a presence/absence survey for the Delhi
Sands FlowerLoving Fly (DSF) on Stratham’s two
parcels (the referenced Components 4 and 7 are
now reclassified as Planning Areas 4 and 8). The
reports have been done every year since 2002. See
Appendix IX, under separate cover, “Report of Year
2002 Focused Survey for Delhi Sands FlowerLoving Fly Components 4 and 7” and see Appendix X, under separate cover, “Report of Year 2003
Focused Survey for Delhi Sands Flower-Loving Fly
Components 4 and 7”). The results and discussion
of the four reports states:
“No DSF or DSF sign (i.e., discarded pupal
cases) were observed on the Survey Site during
the current survey, nor was the DSF detected
on the site during the prior years survey (LMI
2002). Based upon the following factors it may
be concluded that the Survey Site is not occupied
by the DSF in any suitable habitat for the species
present. The results of this and the former year’s
survey as reported herein satisfy the federal requirement to demonstrate the absence of the DSF on the Survey Site.”

2.2.2(f) Paleontological
The “Archeological Resource Evaluation and
Paleontological Records Search” prepared for the
Stratham Group, dated March 12, 2004, Appendix VI
states;
“The results of the paleontological review
showed that the entire project area rests on surface exposures of Quaternary younger fan deposits (Qyf) dating the late Holocene Epoch.

This rock unit has low paleontological sensitivity.

It is possible that older Pleistocene sedimentary
rock units will be encountered at a depth of 15 feet
below the modern ground surface. Paleontological
resource monitoring is recommended if and
only if excavations take place more than 15 feet
below the modern ground surface.”Please see the
Environmental Impact Report, as prepared for the
West Haven Specific Plan, for further details.

2.2.3 Property Ownership
The approximate 202 acre Project Site is currently owned by six separate property owners as illustrated on Exhibit 1-3, “Existing Assessor’s Parcels, Developers and Property Ownership” in Section
1 of the West Haven Specific Plan. Armada LLC,
The Stratham Group, SC Ontario Development
Corporation and Richland Communities, Inc. propose
to immediately develop approximately 150 gross
residential acres of the Project Site. The remaining
approximate 20.1 gross residential acres and the 11.7
acre Neighborhood Center will be developed in the
future.

2.2.4 Existing Circulation
State Route 60 (SR-60) is located approximately twothirds of a mile north of the Project Site. Currently, access to SR-60 is north, via Haven Avenue. In addition, the Project Site is approximately 1.5 miles west of Interstate 15 (I-15). Current, direct access to I-15 is north, via Haven Avenue, then east on SR-60, approximately 1.5 miles. The two freeways provide regional access to the West Haven Specific Plan area.

The Project Site is bordered on the north by Riverside
Drive, Master Planned as a “Standard Arterial” street
in the City’s NMC General Plan TOP. The north onehalf of Riverside Drive has been improved by the development occurring to the north. The Project Site
is bordered on the east by partially improved Haven
1775
SECTION 2 • Existing Project Site Conditions
WEST HAVEN SPECIFIC PLAN 2-7
Avenue, designated in TOP NMC General Plan as a
“Divided Arterial Parkway 2-2,” and bordered partially on the west by Turner Avenue, which is designated as a “Collector Street” in TOP NMC General Plan. Future Chino Avenue, master planned as a
“Collector Street,” is proposed to bisect the Project
Site, east/west, approximately 0.5 mile south of the
Riverside Drive and Haven Avenue intersection.

2.2.5 Existing Infrastructure and Utilities

2.2.5(a) Existing Water
Per the City of Ontario Water Master Plan, the West
Haven Specific Plan area is within two pressure
zones. That portion of the Specific Plan area, north
of Chino Avenue, is within the 1010 Zone and that
portion south of Chino Avenue is within the 925
Zone. Per the Water Master Plan, new facilities will
be required to service the Specific Plan area.

There is an existing 10-inch water line and a 12-inch
water line in Riverside Drive, an existing 12-inch
water line in Turner Avenue and an existing 8-inch
water line in Chino Avenue which terminates at the
westerly boundary line of the Southern California
Edison Company (SCE) easement lying on the west
side of the West Haven Specific Plan boundary. These
waterlines are included in the 1010 Pressure Zone.

On-site residential and agricultural uses within the
Specific Plan Area are served by private wells. There
are four existing wells on the Specific Plan Area as illustrated on Exhibit 2-3, “Existing Wells, Electricity, Natural Gas and Communication Systems.” A well
use/destruction plan and schedule for all existing private/agricultural wells shall be submitted for prior to issuance of permits for any construction activity. If
a private well is actively used for water supply, the
Developer shall submit a plan to abandon such well
and connect users to the City’s water system (residential to the domestic water system and agricultural to the recycled water system) when available. Well
destruction requires permitting from County Health
Department. A copy of such permit shall be provided to the Engineering and Public Works Agency prior to issuance of grading and/or building permits. If the
Developer proposes temporary use of an existing agricultural well for purposes other than agriculture, such as grading, dust control, etc., the developer shall make a formal request to the City of Ontario for such
use prior to issuance of permits for any construction
activity. Upon approval, the Developer shall enter into an agreement with the City of Ontario and pay any
applicable fees as set forth by the agreement.

2.2.5(b) Existing Sewer
Wastewater disposal within the Specific Plan Area is
currently being provided through septic tanks. When
the septic tanks are taken out of commission, they will be destroyed per Department of Health Services (DHS)
requirements. There are two existing sewer lines
in Riverside Drive. Both sewer lines are at capacity
and discharge to the Whispering Lakes pump station
which is also at capacity. There is an existing sewer
system within the Archibald Ranch development,
located westerly of the West Haven Specific Plan.

The existing sewer system connects to a lift station
on the east side of Archibald Avenue. A force main
from the lift station extends northerly along Archibald Avenue to the Whispering Lakes Pump Station. The
Archibald Ranch lift station is at capacity and cannot
accept any additional sewer flows. Upon completion
of the Eastern Trunk Sewer (Archibald Avenue), the
lift station will be eliminated and the sewer system
will discharge into the Eastern Trunk Sewer. Per the
City of Ontario Sewer Master Plan, new facilities will
be required to service the Specific Plan area.

2.2.5(c) Existing Storm Drain
There is an existing storm drain system adjacent to the Project Site, serving the Archibald Ranch Projects.

This storm drain system outlets into Chris Basin
which outlets into the Cucamonga Creek Channel.

Approximately 15 acres of the Specific Plan area,
adjacent to Turner Avenue, was tabled to drain to the
existing Archibald Ranch storm drain. Upon further
study of the capacity of the Archibald Ranch storm
drain, it was determined that the storm drain is at ca1776 SECTION 2 • Existing Project Site Conditions
2-8 WEST HAVEN SPECIFIC PLAN
pacity and cannot accept additional flows. When
the Archibald Ranch storm drain was designed, the
Rational Method from the old San Bernardino County
Hydrology Manual was in use. The Rational Method
has since been revised, which when used, results in
a higher calculated runoff, (Q). There are no other
permanent storm drainage facilities near the project
which may be used for on-site storm flows.

The construction of the County Line Channel is a
joint project of the City of Ontario and County of
Riverside Flood Control District which began construction in May 2004. The channel will begin near the intersection of I-15 and Bellegrave Avenue,
constructed within Bellegrave and will follow the
Riverside/San Bernardino County line terminating in
the Cucamonga Creek Channel.

The West Haven Specific Plan Project Site is protected
from off-site flows from the north by a combination
drainage swale and storm drain line constructed on the
north side of Riverside Drive.

Per the City of Ontario Storm Drain Master Plan, new
facilities will be required to service the Specific Plan area.

2.2.5(d) Existing Electricity
Southern California Edison Company (SCE) provides
electricity to the Project Site. SCE has some overhead
facilities in the area servicing the farms and dairies.

The development of the West Haven Specific Plan
area will increase electrical power requirements and
SCE will develop the required distribution system.

Existing overhead utilities—34.5 kV and lower—
will be undergrounded when development occurs in
compliance with City ordinance. Existing electrical
lines are illustrated on Exhibit 2-3, “Existing Wells,
Electricity, Natural Gas and Communication
Systems.”

2.2.5(e) Existing Natural Gas
The Southern California Gas Company (SCG) provides natural gas service within the Project area.

Facilities in the area include existing 3-inch and 6inch mains in Haven Avenue and a 6-inch line in Riverside
Drive. It should be noted that a 30-foot gas easement
runs diagonally across the Project Site, approximately
500 linear feet south of the intersection of Riverside
Drive and Haven Avenue and exits the Project Site’s
westerly boundary, approximately 1,290 linear feet
south of Riverside Drive. Existing natural gas lines
are illustrated on Exhibit 2-3, “Existing Wells,
Electricity, Natural Gas and Communication
Systems.”

2.2.5(f) Existing Communication Systems
Verizon provides telephone service within the project
area. Currently, telephone service is provided to the
residences, dairies and farms in the area, as illustrated on Exhibit 2-3, “Existing Wells, Electricity, Natural
Gas and Communication Systems.”

2.2.5(g) Existing Solid Waste
The City of Ontario Public Works Agency currently,
by request, provides solid waste collection and disposal to the NMC Ontario Ranch.

2.2.6 Existing General Plan Land Use and
Zoning
As previously noted, the City of Ontario adopted
the New Model Colony GPA on January 7,
1998, which established General Plan Land Use
Designations for the West Haven Specific Plan
area consisting of Residential-Low Density,
Residential-Medium Density, Elementary
School, Neighborhood Center, Greenbelts, Parks
and Neighborhood Park.

Following the adoption of the City of Ontario
GPA for the NMC, the Project Site was pre-zoned
as SP/AG (Specific Plan/Agricultural Preserve).

The zoning designation of “SP” requires the
project area to be developed with a Specific Plan
to carry out the objectives of the New Model
Colony General Plan land uses.

LAND USE PLAN

3.1 Land Use Plan Description
The West Haven Specific Plan is designed as
a high quality, master-planned community. Through
strong cohesive community design, the West Haven
Specific Plan will offer a diverse, convenient living
environment for its residents. The West Haven
community amenities include expanded landscaped
parkways and Neighborhood Edges, which will
accommodate pedestrian and bicycle paths, as
appropriate. In addition, a paseo system will provide
recreational opportunities and alternative modes
of transportation (pedestrian and bicycle) through
the site, within the Southern California Gas and the
Southern California Edison Easements, both on-site
and offsite and within the various Planning Areas. An
elementary school and a five-acre Neighborhood Park
will provide facilities for various forms of recreation.

Another significant feature of the proposed plan is
the Neighborhood Center. Located at the southwest
corner of Haven Avenue and Riverside Drive,
designated as Planning Area 2, the Neighborhood
Center provides service and retail shopping amenities
for local residents. The Neighborhood Center is
proposed to include approximately 87,000 square feet
of commercial, public and quasi-public uses.

The West Haven community will be identified and
unified through design elements, which includes
architecture, signage, landscaping, color, walls,
fencing and entry treatments. Variability of design
will be allowed so individual neighborhoods, within
the overall community, can establish individual
design character, yet maintain compatibility with the
West Haven master plan.

The “West Haven Land Use Plan” is illustrated in
Exhibit 3-1. The Project Site has been divided into
nine (9) eight (8) Planning Areas. The boundaries of
the Planning Areas were dictated by current property
ownerships combined with different and distinctive
types of land uses and residential densities to be
developed within the West Haven Specific Plan. For
specific information regarding development within
each of the nine (9) eight (8) individual Planning
Areas, please refer to Section 8, “Design Guidelines”
and Section 9, “Development Standards.” The
proposed land uses are outlined in the following
subsections:

3.1.1 Residential
The West Haven Specific Plan residential densities
range from 4.86 Dwelling Units (DU)/Net Acre to

6.78 DU/Net Acre as depicted on Table 3-1, “Land
Use Summary.” Currently, 753 1,142 dwelling units
re proposed on approximately 146.9 157.72 residential
allocation acres of land located within Planning Areas
1, 3, 4, 5, 7, and 8, and 9. It is anticipated that the detached residential homes will be located on lots
between 2,800 and 6,300 square feet in addition to
a variety of attached configurations. will be targeted
for a variety of single-family detached and attached
products. The architectural products include American
Colonial, Italianate, American Farmhouse, Craftsman,
East Coast Traditional, French Country, Monterey,
Spanish, Plantation, and West Coast Traditional.

Refer to Section 8.2.3, “West Haven Architectural
Styles” for more details.

3.1.2 Neighborhood Center
The West Haven community will contain a
“Neighborhood Center” on approximately 11.7 gross
acres.

The Neighborhood Center is proposed to include an
approximate 87,000 square feet of gross leaseable area
which will support a supermarket, restaurants, retail
shops, personal, professional and financial services
and community and cultural facilities.

3.1.3 Greenbelt/Paseos and Landscaped
Neighborhood Edges
The proposed Project Site will include a system of
greenbelt/paseos, Neighborhood Edges and internal
paseos containing pedestrian links. The paseos and
edges link the West Haven community’s neighborhoods
to each other while providing alternative modes of
travel (pedestrian, bicycle, etc.) to major destination points (schools, recreation facilities and the
Neighborhood Center) within the community. The
paseos generally follow existing easement corridors.

Major roadways, shown on the West Haven Specific
Plan, will also have Neighborhood Edges (expanded

4.1 Circulation Plan Description
The main objective of the Circulation Plan is to
provide direct and convenient access to individual
residential planning areas, employment and service
land uses through a safe and efficient transportation
network including Divided Arterial Parkway 2-2,
Standard Arterial, Collector and Interior Streets and
a pedestrian, bicycle paseo/sidewalk system.

4.2 Vehicular Circulation
Existing roadways, which will provide access to
and from the Project Site, include Riverside Drive
(Standard Arterial Street) serving as the northerly
boundary of the Project Site; Haven Avenue
(Divided Arterial Parkway 2-2) serving as the
easterly boundary of the West Haven community;
Turner Avenue (Collector Street) serving as a partial
westerly boundary and Chino Avenue (Collector
Street) providing east/west access through the
Project Site. Additionally, off-site regional access
to and from the SR-60 Freeway will be from
Archibald Avenue, located to the west, and Haven
Avenue, serving as the eastern boundary of the
West Haven Specific Plan. The design speed for
each street is as follows:

Haven Avenue and Riverside Drive 45 mph
Chino Avenue and Turner Avenue 40 mph
On-site circulation within the West Haven Specific
Plan will be provided through a system of local
streets to be constructed internal to the project.

All interior neighborhoods will have a minimum
of two (2) points of access. Riverside Drive and
Chino Avenues will connect east/west traffic and
Haven and Turner Avenues will connect north/
south traffic flow. The elementary school site will
have driveway access limitations (right turns in
and out) and all student dropoffs and pick-ups,
either by bus or private automobile, shall be
accommodated on the school property. Further
information regarding traffic reports, impacts and
mitigation measures will be presented in the West

Avenue and a 6-inch line on Riverside Drive. It
should be noted that a 30-foot gas line easement runs
diagonally across the Project Site at approximately
500-feet, south of the intersection of Riverside
Drive and Haven Avenue and exits the Project Site’s
westerly boundary at approximately 1,290 feet south
of Riverside Drive.

5.3 Communication Systems
A fiber optic system will provide phone, cable,
and internet access to all homes within the NMC
Ontario Ranch. The City will provide a fiber optic
network to the home, accommodating voice mail
data, cable and video on demand. Proposed on-site
facilities will be placed underground within a duct
and structure system that will be installed by the
developer, as shown in Exhibit 5-1, “Fiber Optics
Plan.” Maintenance of installed system will be the
responsibility of the City and/or Special District
fiber optic entity and not the developer(s), private
homeowners association or private homeowners.

Developer(s) of the Specific Plan will need to
provide all fiber optic infrastructure necessary to
service their site as a stand-alone development.

5.4 Public Utilities
Water, recycled water and sewer utilities may be
designated as “public utilities” if located within public or private streets. All public utilities within private streets shall be designed per City standards and
contained within acceptable easements. The CC&Rs
shall contain language that requires all proposed work
by the HOA within said easements to be plan checked
and inspected by the City, including applicable fees.

Generally, utilities will not be accepted as public

5.7.1 NPDES Compliance
The grading and drainage of the West Haven Specific
Plan area shall be designed to detain, filter and
treat surface runoff, in a manner and combination
which is practical, to comply with the most recent
requirements of the San Bernardino County NPDES
Storm Water Program’s Quality Management
(WQMP) for significant new development projects.

The objective of the WQMP for this project is to
minimize the detrimental effects of urbanization on
the beneficial uses of receiving waters, including
effects caused by increased pollutants and changes in
hydrology. These effects may be minimized through
the implementation of site designs that reduce runoff
and pollutant transport by minimizing impervious
surfaces and maximizing on-site infiltration, Source
Control Best Management Practices (BMP’s) and/or
either on-site Structural Treatment Control BMP’s,
or participation in regional or watershed-based
Treatment Control BMP’s.

Prior to the issuance of a grading or construction
permit, a Storm Water Pollution Prevention Plan
(SWPPP) will also be prepared. The SWPPP will
be prepared to comply with the California State
Water Resources Control Board’s (State Water
Board) current “General Permit to Discharge Storm
Water Associated With Construction Activity” and
the current Area Wide Urban Storm Water Runoff
(Regional NPDES Permit). The SWPPP will identify
and detail all appropriate Best Management Practices
(BMP’s) to be implemented or installed during
construction of the project.

In addition to the preparation of a SWPPP for
construction-related activities, and as part of the
approval of any grading plans within the Specific Plan
Area, the applicant will be required to submit a Water
Quality Management Plan (WQMP) on the regional
model form provided by the City. The WQMP shall
identify and detail all Site Design BMP’s, Source
Control BMP’s and Treatment Control BMP’s to be
implemented or installed at this site in order to reduce storm water pollutants and site runoff.

5.7 Storm Drain
The City’s Storm Drain Master Plan identifies new
storm drain facilities to serve the Project Site. Off
Site master plan storm facilities include the Turner
Avenue Storm Drain extending northerly from the
County Line Channel within Turner Avenue to the
Southwesterly corner of the Project Site. On Site
master plan facilities include extending the Turner
Avenue Storm Drain from the southwest corner of
the Project Site extending it easterly across Planning
Area 9 to approximately 120 feet east of the SCE
Corridor, then northerly along a proposed north/south
local street to the southerly line of Planning Area 1.

The alignment of the on-site Turner Avenue Master
Plan Storm Drain extends across all of the residential
planning areas, the concept park, an SCE Easement
and the SCE Fee Parcel. A public utility easement will
be required across the concept park, SCE Easement
and SCE Fee Parcel. The developer(s) of West Haven
will construct all required Master Planned Storm
Drain required to serve the Specific Plan Area.

If the Storm Drain Master Plan is revised or updated
by the City those updates will be incorporated into the West Haven Storm Drain System Improvements.

Local storm drain system improvements to serve the
proposed planning areas within the Project Site will
be connected to the proposed Turner Avenue Master
Plan Storm Drain and will be the responsibility of the
planning area developer.

The master plan storm drain improvements are
illustrated in Exhibit 5-5, “Master Plan Storm Drain
Improvements.”
Interim facilities like on-site detention basins of
adequate size(s) will be required to be constructed if
no outlet storm drain system is built or existing at the time of development of this project.

to Schaefer Avenue, a 30-inch recycled main in Chino
Avenue from Archibald Avenue to Haven Avenue, a
16-inch recycled water main in Haven Avenue from
Chino Avenue to Edison Avenue, a 16-inch main
in Edison Avenue from Haven Avenue to Schaefer
Avenue, and a 16-inch main in Schaefer Avenue
from Edison Avenue to Archibald Avenue. Initially,
the recycled water from the 1050 Pressure Zone will
be conveyed to the 930 Pressure Zone via two (2)
master planned pressure reducing stations located in
Archibald Avenue and Haven Avenue north of Chino
Avenue. The ultimate source of recycled water to the
Specific Plan within the 930 Pressure Zone is IEUA’s
RP-1 via the future 30-inch RP-1 Outfall Parallel
located west of the Cucamonga Channel and delivered
through master planned lines that connect to RP-1
Outfall at Chino Avenue, Schaefer Avenue, and other
major intersections. The Project Site developers will
be responsible for these new distribution lines. All
recycled water lines required to serve the project,
will be provided by the West Haven Specific Plan
developer.

Within the project site, 8-inch recycled water mains
are proposed to serve the site. The West Haven
Specific Plan shall comply with City Ordinance 2689
and make use of recycled water for all approved uses,
including but not limited to the irrigation of parks,
schools, street landscaping, recreational trails, HOA
maintained common areas and commercial/industrial
landscaping. The developer shall prepare and secure
approval of an Engineering Report from the City of
Ontario and the Department of Health Services prior
to the use of recycled water. The proposed on-site
recycled water system shall be constructed and cross
any and all SCE easements within streets. Sizing
of on-site system is subject to the approval of the
hydraulic analysis and minimum requirements from
the City.

There may be an interim period where recycled water
supply does not have adequate pressure depending
on the timing of development and construction of
a regional booster station. If this is the case, the
recycled water system will connect to the potable
system initially, until such point that recycled water
service is available.

The recycled water system improvements are
illustrated in Exhibit 5-6, “Master Plan Recycled
Water Improvements.” The conceptual on-site
recycled water system is illustrated on Exhibit 5-7,

OPEN SPACE AND

RECREATION PLAN

6.1 Open Space and Recreation
Plan Description
A major feature of the West Haven Specific Plan
is the system of expanded landscaped parkways
(neighborhood edges) and paseos, which link various
facilities within the community. The proposed
facilities provide an array of recreational opportunities in which all members of the community can participate.

Further, these facilities incorporate a cohesive plan that interrelates with and links the various neighborhoods
of the West Haven community with each other and to
destination points, such as the proposed Neighborhood
Park, the proposed Neighborhood Center and the
regional trail system master planned within the New
Model Colony Ontario Ranch area. Recreational
opportunities vary from active, with potentially
structured recreational programs, to passive.

The various recreational facilities are linked to each
other and to other elements of the community with
an extensive neighborhood edge and paseo/greenbelt
system, which will be landscaped as discussed in
Section 8.8, “Landscape Design Guidelines.” The
neighborhood edge/paseos will, at a minimum, contain
one or more pedestrian paths that are oversized.

Bicycle paths (Class I) will be provided as shown
on Exhibit 4-1, “Circulation Plan” and discussed in
Section 4.3, “Bicycle Plan” of this document.

The project proposes a total of approximately 14.6 9.6
acres of parks/open space/recreation. This is based on:
• 7.0 +/- acres of proposed pocket parks and the
30-foot wide paseo to be developed within the
Project Site Boundary.
• 5.0 acre Neighborhood Park.
• 2.6 acres of 30-foot wide paseo to be developed by
West Haven within the SCE Easement, adjacent to
the project boundary.

6.1.1 Park and Recreational Opportunities
Recreational opportunities are those opportunities
which are available for the use and enjoyment of
residents of the West Haven community and the
general public. They are discussed as follows:

Neighborhood Park
A five (5) acre Neighborhood Park is proposed
in Planning Area 6. The park facility amenities may
include the following:
• Children’s Play Areas
• Sports Field
• Family Picnic
• Public Restrooms

6-2 WEST HAVEN SPECIFIC PLAN
Parkway / Paseo System
An expanded parkway system (neighborhood edge
[N.E.]) will be located adjacent to backbone and
higher volume roadways. The neighborhood edge
system will be landscaped with turf, trees and various
additional plant materials. Community “theme”
signage will be located adjacent to the edges.

Sidewalks will be provided within the neighborhood
edge as well as a Class 1 Bike Path along Haven
Avenue.

The landscaped paseos will be 30-feet in width and
will incorporate existing Southern California Edison
Company (SCE) property and easements (both
onsite and off-site) and the Southern California Gas
Company easement to provide a comprehensive
paseo network. This network runs from the Project
Site’s southern boundary, within the SCE parcel,
north to Riverside Drive, within the adjacent off-site
SCE easements/property.

This parkway/paseo system will provide
approximately 7.6 acres of additional open space /
park amenities. Exhibit 3-1, “West Haven Land Use
Plan,” depicts the conceptual locations of the paseos.

6.2 Open Space And Recreation
Plan General Development Standards

1. General Development Standards to the
Neighborhood Park will include the following:
• The Neighborhood Park boundaries and
configurations are approximate and subject to
adjustment with more detailed site planning
and design. The boundaries may be modified
or relocated entirely within the same general
area, subject to the approval of the City of
Ontario, without requiring an amendment to
the West Haven Specific Plan. However, at
no time will the park total less than five acres
net, exclusive of street paving.
• All Neighborhood Park improvements
shall provide for pedestrian circulation and
handicap accessibility.
• The City shall approve all lighting design,
fixture location(s) and lighting types within
the park. The pathway and parking area
lights shall be controlled by a timing system,
programmed from dusk to dawn.
• All lighting within the Neighborhood Park
shall be provided with glare screens as may be
needed to direct light away from the adjacent
residential areas and to reduce the impact of
the lighting on these residential areas. Where
appropriate, every effort shall be made to
reduce the amount of light that is not directly
needed for the safe use of the facilities. This
is to be accomplished by the height of the
fixtures, the placement of the fixtures away
from residential areas, and the type and design
of fixtures.
• The Neighborhood Park project will be
granted credit toward the park component of
the City’s Park Fee Reimbursement.

2. All recreational and open space areas shall be
landscaped and contain permanent, recycled
water irrigation systems.

3. All recreational facilities shall provide parking
in accordance with the City of Ontario’s Parking
Ordinance.

4. Landscaping within recreation and open space
areas shall be further governed by Section 8.7.2,
“Landscape General Development Standards,”
and Section 8.8, “Landscape Design Guidelines”
of the West Haven Specific Plan.

5. The design of the Neighborhood Park will require
approval of the City of Ontario.

6. Pocket park acreage calculations for residential
development shall be based upon a minimum of
two (2) acres per 250 dwelling units. Based on
753 1,142 total units, the pocket park requirement
would total 6.0 9.1 acres.

SECTION 7 • Grading Plan
WEST HAVEN SPECIFIC PLAN 7-1
SECTION 7

GRADING PLAN

7.1 Grading Plan Description
The existing ground has a uniform slope of
approximately 2% trending towards the southwest.

The grading operation will generally consist of
the removal of any manure left over from the dairy
operations, clearing and grubbing, demolition of
existing structures and moving surface soils to
construct residential and commercial building pads
and streets. Manure left over from dairy operations
can be recycled into compost at a much reduced cost
than removal to a landfill. This process, Residuals
Composting, can take several weeks to a few months
depending on the amount of material to be removed.

A local contact providing this service is Ed Needham
at Synagro and can be reached at (800) 661-7922 or
[email protected].

Where slope conditions are present, the property line
shall be located at the top of a slope. See Exhibit 7-1, “Conceptual Pad Placement in Slope Conditions”.

In areas adjacent to a ridgeline or in moderate slope
areas, dwelling units and structures should be sited to:
• Use the natural ridgeline as a backdrop for
structures;
• Use landscape plant materials as a backdrop; and
• Use structure to maximize concealment of cut
slope.

If retaining walls are required, the following criteria shall be used:
• Exposed walls and fences facing roadways shall
be no greater than 3-feet retaining (9-foot total
wall) in height, except as necessary for acoustical
purposes to satisfy the intent of the noise
ordinance.
• Where retaining walls or fences face roadways,
they shall be built, when feasible, of decorative
materials consistent with the wall theme of the
neighborhood.

The amount of removals and depth of overall
excavation will vary within the properties in the West
Haven Specific Plan depending on prior use of the
land.

The Conceptual Grading Plan is included as Exhibit
7-2, “Conceptual Grading Plan”.

7.2 Grading Plan General
Development Standards
Grading plans for each tract in the West Haven
Specific Plan area will be prepared by a Registered
Civil Engineer and reviewed and approved by the
City of Ontario Building, Planning and Engineering
Departments prior to the issuance of grading permits.

All grading plans and activities will conform to the
City Grading Ordinance dust control and erosion
control requirements, as well as those outlined in the
approved SWPPP.

DESIGN GUIDELINES

8.1 Introduction
Building upon Ontario founder George Chaffey,
Jr.’s vision of a walkable, traditional residential
community, the West Haven community design is
rooted in the hospitable small town ethos of Ontario’s
early 1900s era past while also adapting to the
recreational requirements of today’s active Southern
California family lifestyles. West Haven will be
a place where children and their parents can walk
along shady tree lined sidewalks to school or to the
store, or explore the wide open spaces along paseos
and neighborhood parks, and neighbors join together
to celebrate the Fourth of July with bicycle parades
and block parties. Pedestrian friendly streets feature
attractive landscaping, architecture-forward and rear
access site planning with streetscenes and parks
activated by authentic architecture with ample front
porches and patios.

To realize West Haven’s vision as both a nurturing
and welcoming place to live, the development team
has produced the West Haven Design Guidelines.

Design guidelines create an identity and cohesiveness
for West Haven. They ensure a unifying theme for
the entire Specific Plan area, while accommodating
the individual neighborhood design considerations
as required by each of the Project site’s uses
which include Residential, Neighborhood Center
Commercial, Educational and Recreational activities.

This section provides a general yet flexible standard
set of concepts, goals and criteria for planning,
architectural and landscaping encouraged in the
design of homes and facilities of West Haven. The
appropriate selection of architectural styles, materials, landscaping and massing are important to creating a
quality living environment.

8.1.1 Purpose
The purpose of the Design Guidelines is to provide
advisory and supplemental guidance to implement
the West Haven vision in order to direct its desired
development outcome. This information is important
to future project development because it describes the
basic design and planning principles upon which more
specific design standards are based. Observing these
guidelines will help assure that the promise of the
vision for West Haven will be fulfilled.

8.1.2 Intent
The overriding design intent is the creation of a
warm and friendly community environment that
encourages walking, socializing, an appreciation of
both nature and local culture, and an economically
vitalized destination. The overall character is
intended to convey an environment that is cognizant
of the historical significance of West Haven while also relating to adjacent districts and the broader City of
Ontario. Therefore, the designers of West Haven are
encouraged to be mindful of the area’s natural and
cultural histories, local climate, and terrain. Each
aspect of every project is viewed as a significant
element in reinforcing the West Haven community
concepts, and its expression of quality is highly
influential on the overall essence and integrity of the whole.

The goal of the design guidelines is to create a unique community within the New Model Colony Ontario
Ranch, yet reminiscent of Ontario’s heritage. The
guidelines express “intent” rather than “absolutes,”
thereby allowing certain flexibility in fulfilling the
intended design goals and objectives. The principal
design criteria and architectural styles are not intended to be restrictive, but are meant to assist in the design, processing, and implementation of a high level of
design direction and quality. The goal is to promote
both visual compatibility and variety in a community
setting achieved by utilizing a number of compatible
styles, and allow for quality architectural innovation.

Great neighborhoods result from the synthesis of
innovative architecture and successful site and
landscape design techniques.
1812
SECTION 8 • Design Guidelines
8-2 WEST HAVEN SPECIFIC PLAN
Successful site design techniques will include:
variable lot setbacks, pedestrian connections,
shortened streets, curb separated sidewalks, street
trees program, and a limited number of homes per
neighborhood.

The graphic representations contained herein are
for conceptual purposes only and are to be used as
general visual aids in understanding the basic intent
of the guidelines; they are not meant to depict any
actual lot or building design.

These design guidelines, and the criteria they contain, will be implemented and enforced through the review
of plans submitted by developers and official design
review by the City of Ontario.

These guidelines are organized into the following
sections:
• Residential Architectural Design
• Massing, Plotting and General Neighborhood
Design Criteria
• Materials & Details
• Home Types
• Nonresidential Architectural Design
• Landscape Design
• Implementation

8.2 Residential Architectural
Design

8.2.1 Introduction & Guiding Principles
Introduction
The residential architectural design intent for West
Haven is to emphasize a diversity of styles, floor
plans, garage placements, materials and colors. In
keeping with the overall community theme, the homes
will be of high quality and contribute positively to the character of both the West Haven community and
the City of Ontario. Overall, the design concept is
to blend the traditional architectural styles found in
Ontario and Southern California with contemporary
lifestyles, current building methods and emergent
technologies. Additionally, these styles incorporate
detailing appropriate to the setting. Diversity is a
fundamental guiding principle at West Haven. This
ensures that neighborhoods are varied and that blanket
uniformity is avoided.

Conceptual emphasis is on specific interpretation of
styles within the constraints and consistency of site
planning, landscape and architecture, as well as on
specific use and selection of details that correlate
well with the designed floor plan, emphasizing such
architectural concepts as:
• “Architecture forward” to support a pedestrian
friendly environment,
• Varied garage placement and orientation to add
richness and variety to the neighborhood,
• Variety of compatible architectural styles as well
as a mix of detached and attached housing types
and sizes,
• Wrap around architectural detailing, where
appropriate; buildings may be viewed from
all public areas, both inside and outside each
neighborhood, including common open space
areas, sidewalks, alleys and streets,
• Varied roof heights and pitches to create a feeling
of richness, and
• Color palettes shall be selected per styles, using
consistent materials and colors as a “unifying
theme” to connect the varying residential
products and nearby commercial and educational
buildings.

The following characteristics in concept designs
shall be avoided:
• Inappropriate scale,
• Poor selection and execution of details,
• Plotting of the same design adjacent to one
another,
• Extreme interpretations of the characteristics for
each style, and
• Lack of window treatments, which result in
flat, blank walls, specifically on side and rear
elevations facing streets or other public spaces.
1813
SECTION 8 • Design Guidelines
WEST HAVEN SPECIFIC PLAN 8-3
Guiding Principles
Guiding Principles of residential architectural design
for West Haven:

Buildings should contribute to a qualitative nature of
neighborhood.
• Appropriate scale and proportions should be used
in massing and details.
• Transitional spaces between public and private
spaces (courtyards, porches, low walls, etc.)
should be implemented.
• Building setbacks at front and rear should be
varied.
• Massing and articulation should be varied.
• Garage placement should vary from lot to lot.

Buildings should have an enduring quality.
• Design should draw inspiration from the rich
and diverse Southern California architectural
heritage.
• Native materials and colors should be used.
• Authentic details and ornamentation should be
emphasized.

Buildings should be designed with architectural
sensitivity to human scale.
• Doors, windows, indoor and outdoor spaces should
be intimate and secure.
• Designs should not overpower the overall
streetscape.

Buildings should be appropriate to the climate and
context.
• Shading and shaded areas should be provided to
protect from intense summer sun
• Protection from adverse weather should be
considered using a variety of techniques in
designs.
• Buildings should compliment and reflect the
surrounding environment.
• Design should encourage outdoor interaction with
the temperate Southern California climate.

Buildings should be designed of materials and
techniques appropriate to achieving realistic
hard cost objectives (see Simple Home Design
section).
• Efficient structural systems should be considered.
• Consistent window and door sizes are encouraged.
• Use of standard modules and sizes is encouraged.

8.2.2 Residential Architectural
Philosophy
Southern California has a rich legacy of early
agriculturally based towns, such as Ontario, that
have fostered a variety of traditional architectural
styles. As these towns were being established,
architectural styles were often imported from the
Midwest and East Coast in the form of pattern
books from which the builders chose the style
and massing of their homes. Placed in the setting
of “sunny” Southern California, the styles were
then often modified to meet specific climatic
influences of the region. Outdoor spaces became
more prominent and useful year-round, colors were
light earth tones and materials included a blend of
plaster, stucco and siding.

Additionally, the Spanish history of Southern
California also influenced the architecture of the
region. Brought to the region by Spanish settlers and
missionaries, these homes were well suited for the
temperate climate of Southern California.

Therefore the theme of West Haven’s residential
architecture is based on these architectural styles
historically found in Ontario. West Haven’s homes
shall age gracefully over time, contributing to the
sustainability and vitality of the neighborhoods.

All architectural styles have been chosen for their
traditional forms and timeless character that reinforces the charming nature of the neighborhoods and historic
Ontario.

All architectural styles outlined in these guidelines
shall be interpreted with authenticity. Simple yet
detailed forms are crucial to the success of the
community. All architectural styles must be detailed
with elements that represent the best interpretations.
1814
SECTION 8 • Design Guidelines
8-4 WEST HAVEN SPECIFIC PLAN
Homes shall be designed with a few particular styles
in mind prior to the beginning of the design process. A home designed to a particular set of compatible styles
is always stronger than a home that has a style applied after the floor plan has been designed.

Additionally, each home is expected to provide a “gift
to the street” – a positive contribution to the public
realm. Specific elements may include, but are not
limited to, architecture forward, porches, recessed
garages, covered terraces, enhanced elevations, and
landscape. The resulting architectural expression
should be sensible in its approach and unique in its
outcome.

Builders are required to conform to the following
variety of differing Floor Plans and Elevations:

Number of
Dwelling Units
Number of Differing Floor Plans
and Elevations
5-10 As required by Planning Commission
11-25 2
26-50 3
51-75 3
76-100 4
Over 100 4; +1 additional floor plan with 4 elevations for each additional 50 units exceeding 100
Residential Architectural Design Objectives:
• Emphasize styles of architecture that are
compatible, yet vary enough to create interest and
diversity.
• Focus on traditional, more timeless styles of
architecture.
• Interpretations of styles that are authentic to the
extent feasible.
• Create a dynamic streetscape through variation in
floor plan and elevation plotting.
• Emphasize articulated building massing.
• Emphasize front elevations that relate strongly to
the street and contribute to the livability of that
realm.
• Design certain homes specifically for corner
conditions.
• Utilize authentic materials and colors that
reinforce the overall design theme.

8.2.3 West Haven Architectural Styles
The architectural character of West Haven’s
neighborhoods shall consist of complementary
traditional architectural styles. As an architectural
pedigree, they reinforce West Haven’s connection
to Ontario’s early beginnings, building upon a
rich heritage of traditional neighborhood design.

Additionally, the chosen styles complement one
another through overall scale, massing, proportions,
details, and the ability to establish a charming
architectural backdrop that will age gracefully over
time. The materials and colors of these home styles
shall complement the overall landscape design of
the neighborhoods. Each style shall be developed
appropriate to the region, addressing the needs and
lifestyles of the residents.

Acceptable residential architectural styles:
• American Colonial
• Italianate
• American Farmhouse
• Monterey
• Craftsman
• Plantation
• East Coast Traditional
• Spanish
• French Country
• West Coast Traditional
Note: Builders may submit home designs using alternative architectural styles to those listed above, provided they are appropriate to the region, environment and setting and subject to the Planning Department’s review and approval.

The styles selected for West Haven share similar
design attributes. Specifically, these styles:
• Are compatible and complimentary, as well as
support the community theme reflective of Ontar
io’s historic development pattern.
• Address the needs and lifestyles of Ontario’s
residents, and are generally accepted by the
market.
• Can be implemented using current building
methodologies and techniques.
1815
SECTION 8 • Design Guidelines
WEST HAVEN SPECIFIC PLAN 8-5
• Can be creatively and diversely interpreted in a
number of ways.
• Have an historic and/or stylistic relevance to the
region, and therefore are timeless in nature.
• Can be interpreted in contemporary and/or
regional adaptations.

It should be noted that Architectural Styles illustrated on Exhibits 8-1 through 8-10, are representative of
architectural styles envisioned for the West Haven
Specific Plan. The intention is to incorporate many of
these design features into the proposed West Haven
community. However, it must be acknowledged that
these styles may be subject to future refinements
based upon buyer preference, detailed engineering,
and other factors. Therefore, the photographs shown
are not intended to be exact duplicates of the future
product types for West Haven, but samples of quality
design elements.

The following examples for each of the ten architectural styles proposed are strongly encouraged and appropriate for the various West Haven neighborhoods.

8.2.3.1 American Colonial
History and Character
This classical style descends from the first saltbox
homes built in the New England colonies in the 17th
century and later evolved into more neoclassical forms
with America’s increasing prosperity. There are many
smaller American Colonial and Neoclassical Revival
Bungalow homes in Ontario, mostly in and around the
Downtown area. Exhibit 8-1, “American Colonial
Architectural Style” illustrates the following:

General Attributes
Massing:
• Simple plan form & massing
• Symmetrical front façade, often with small
centered porch
Roofs:
• Gable roof at medium to moderately steep pitch
• Architectural quality asphalt shingles or concrete

Windows and Doors:
• Vertical gridded windows at front elevations and
in high visibility areas, single-light windows on
sides and rear elevations
• Windows are symmetrically balanced, typically
rectangular double- or single-hung windows with
wood or vinyl frames
• Doors are simple and typically stained or painted

8.2.3.2 American Farmhouse
History and Character
With roots traceable to both Midwestern and Colonial
styles appearing in the mid-to-late-19th century
during America’s westward expansion, the American
Farmhouse style represents a practical adaptation of
balloon framing techniques of earlier rural American
architectural types. New England variations tend
toward more symmetrical elevations with dormers
and two-story massing, whereas the more picturesque
and decorated asymmetrical facades are typical of
the Midwestern variety. This Victorian-era style is
included as a tribute to West Haven’s dairy past.

8.2.3.3 Craftsman
History and Character
Developed as a contradiction to the Victorian era
that preceded it, the Craftsman style evolved from
the Arts and Crafts movement that originated in
England in the late 1800s. It was the first style that
emphasized natural materials and functionality; the
details were simple, contradicting the gingerbread
visage of the Victorian home. The wood is stained,
instead of painted, and the homes feature built-in
cabinets, buffets and benches. The moldings and

• Stained glass windows as an accent to an interior
or exterior feature
• Painted color schemes typically consist of three
(3) to five (5) colors
• Base colors are typically dark earth tones, usually
browns or greens
• Trim colors are typically in contrast to the base
color; darker homes use lighter color earth tones
such as beiges and tans, with lighter homes using
darker trim colors
• Window frames and end rafters use a third accent
color, closer in shade to the base color
• An alternative to the above color scheme would
be mixing color palettes, for example, a maroon
base, an olive green trim and a dark brown
window frame
• Exposed roof and porch beams typically painted
dark brown

8.2.3.4 East Coast Traditional
History and Character
One of the many Colonial Period Revival styles that
became popular during the 1920s, the East Coast
Traditional style took elements from America’s colonial past, including Cape Cod, Georgian, and Federal styles. The style is simple and symmetrical, yet has
a variety of different roof forms. This style is also
adapted as a variation of the Bungalow style. There

There are several excellent examples of the Craftsman
style in Ontario, along with an abundance of
Craftsman Bungalows, which is the dominant home
style in Ontario’s historic neighborhoods. Exhibit 83,

8.2.3.5 French Country
History and Character
One of the many period revival styles that began
in the 1920s and became popular in the late 1920s
to early 1930s, the French Eclectic style replicated
the cottages that dotted the French countryside, and
were popular in fairy tales. Noted for its substantial
use of rusticated stone, this asymmetrical, informal
style should not be confused with the more decorative “Beaux-Arts” style. There are many examples of French Eclectic country homes in Ontario, primarily in the Rosewood Court Historic District. Exhibit 8-5, “French Country Architectural Style,” illustrates the following; General Attributes
Massing:
• Asymmetrical massing with vertical proportions
and either small or no porches
Roofs:
• Steep pitched gable roof (or variations of the
gable roof, i.e., cross gable, etc.) often with
subtly flared curves at the eaves
• Concrete tile roof to mimic wood shake
Windows and Doors:
• Windows are typically individual casement,
double or single-hung gridded windows of either
wood or vinyl frames
• Stained glass windows may be used to accent an
interior or exterior feature
• Doors are typically simple, often with stained
wood finish, and can include stained or beveled
glass panels
Details, Finishes & Colors:
• Stucco exterior walls combined with a variety
of exterior surface materials, often with stone or
brick
• Large, often central chimneys
• Homes typically painted in color schemes consisting of three (3) colors • Base colors are typically light earth tones; trim
colors are typically in contrast to the base color
• Window frames tend to be dark colors
• Round silo type towers required on 33% of
homes in style per neighborhood
• Optional curved roof ridge to simulate thatched
roof or wood shake roof with wavy pattern

8.2.3.6 Italianate
History and Character
Like many Victorian-era styles, Italianate emphasized
vertical proportions and richly decorative detailing on residential structures in America from about 1870 up
until the turn of the century. Italianate is characterized by a low pitched hip roof, wide overhangs, bracketed
cornice, a variety of fenestration, molded window
surrounds, and occasionally a cupola or balustrade
balcony. Simple Italianate structures have a hip roof,
bracketed eaves, and molded window surrounds;
Italianate townhomes feature wide projecting cornices
that conceal a flat or low pitched roof behind.

Some of Ontario’s commercial buildings were
originally designed with Italianate elements. While not typically built in Ontario, the Italianate style is easily compatible with Ontario’s historic neighborhoods.

Exhibit 8-6, “Italianate Architectural Style”
illustrates the following:

8.2.3.7 Monterey
History and Character
The Monterey style is a cross between the adobe
architecture of the Mission period in California and
the New England Colonial architecture prevalent
in the mid 1800s. The homes are a basic colonial
house, typical of New England, with a second floor
porch added to it. The home then took the common
features in adobe architecture, including stucco
walls, and incorporated them into the design. The
Monterey style is rare in Ontario, with only a handful
of examples. Exhibit 8-7, “Monterey Architectural
Style,” illustrates the following:

8.2.3.8 Plantation
History and Character
Similar to the traditional rural East Coast styles to the north, the Plantation style draws it inspiration from the sun-drenched American Southeastern landscape with
its emphasis on outdoor living areas and verandas.

Both the New Acadian Greek revival estates and the
Spanish Colonial porous limestone coquina of St.

Augustine indicate the 18th and 19th century historical roots of the Plantation style; however, whimsical
Victorian decorative elements found throughout the
Caribbean islands are often blended into this Creole
hybrid style. While not typically built in Ontario, the Plantation style is easily compatible with Ontario’s
historic neighborhoods and is included, along with
American Farmhouse, as a tribute to Ontario’s rural
past. Exhibit 8-8, “Plantation Architectural Style,”

8.2.3.9 Spanish
History and Character
The Spanish style was developed as a direct result of
the California Mission style and is a loose adaptation
of features found in detailing from various influences, yet unified by the order of arches, strong form and
mass, plain wall surfaces, and tile roofs. Most formal
designs were influenced more by Italian architecture,
and most informal designs were influenced by
Spanish and Portuguese architecture. The style’s
close relation to outdoors is expressed through use of
terraces, arcade porches, courtyards, colonnades and
patios. The most famous example of the style is the
Adamson House in Malibu.

There are only two known examples of the style in
Ontario. The first is on Princeton Street, within the
College Park Historic District. The second is the Old
Post Office, which was designed by Paul Williams.

Exhibit 8-9, “Spanish Architectural Style with
Window, Chimney, and Vent Details,” illustrates the
following:

General Attributes
Massing:
• Asymmetrical massing
Roofs:
• Low- to moderately-pitched terra cotta or concrete
barrel or “S” shape tile roofs with modest to
generous overhang
• Simple tile rakes and occasional eaves
Windows and Doors:

which are often arched, or with occasional raised
or molded pediments
• Typically individual casement windows with wood
or white vinyl frames
• Vertically hung 9 and 12 paned windows on front
façade
• Either wood or black wrought iron are used for
window grates and balconies, which may also
feature awnings designed for sun control
• Typically carved wood front doors, or other ornate
wood (or fiberglass) doors of painted or stained
finish; French doors
Details, Finishes & Colors:
• Frequent use of pergolas, arched stucco column
porches, and formal axial garden design
• Decorative metalwork on window grills, doors,
balconies, and roof supports
• Garage door patterns complimentary to style

8.2.3.10 West Coast Traditional
History and Character
The West Coast Traditional style is the late 20th
century refinement of the Minimal Traditional
style, which was a transition between the revival
styles of the 1920s and 30s and the post-war Tract
homes. The Minimal Traditional style referenced
traditional styles without actually achieving them,
incorporating elements common to many styles, but
belonging exclusively to none, including columns,
gables, chimneys, and shutters. Houses of this style
may be built of virtually any traditional material; brick and stucco are common. Roofs always lack the eaves
or overhangs found on more assertive styles. Earliest
existing examples in Ontario are one or 1-½ stories
in height. Exhibit 8-10, “West Coast Traditional
Architectural Style,” illustrates the following:

General Attributes
Massing:
• Asymmetrical massing with single story wings
and small front porch
Roofs:
• Gable roof with dormered windows, or
occasionally saltbox roof forms
• Medium to moderately high roof pitch
• Flat concrete roof tile or shake appearance and
moderate overhangs
• Front gable ends with cornice trim
Windows and Doors:
• Windows are typically vinyl or aluminum,
double-hung with gridded panes in high visibility
areas
• Round top accent or bay windows
• Doors are typically painted and may include glass
panels
Details, Finishes & Colors:
• Garage door patterns complimentary to style
• Decorative details on windows, typically shutters
• Variety of exterior surface materials, often with
siding or brick combined with stucco, changes
occurring at inside corners

8.3 Massing, Plotting & General
Neighborhood Criteria

8.3.1 Introduction
The following sections describe plotting and massing,
garage placement and building elevation techniques
that will assist in designing a successful streetscene
for either detached or attached multifamily residential products. Appropriate use of these methods shall ensure the achievement of the desired results.

This section of the guidelines is intended to provide suggestions for creating neighborhoods and streetscenes that have a variety of building forms that are more proportionate to a human scale and more
welcoming to the pedestrian. An important goal of
these guidelines is to compose a street scene possessing both functional and visual variety. The plotting exhibit 8-10: west Coast traDitional arChiteCtural style 1827

8.3 Massing, Plotting & General
Neighborhood Criteria

This section of the guidelines is intended to provide
suggestions for creating neighborhoods and
streetscenes that have a variety of building forms
that are more proportionate to a human scale and
more welcoming to the pedestrian. An important
goal of these guidelines is to compose a street scene
possessing both functional and visual variety. The
plotting and massing, garage placement and building
elevation criteria are intended to provide this desired variety as well as a sense of uniqueness for each
home. Exterior massing of the home should reflect
the general uses inside and be organized to create a
positive street environment.

The required characteristics listed below describe the
desired community setting and streetscene objectives
for the neighborhoods of West Haven:

Objectives:
• Limit the numbers of homes per neighborhood.
• Integrate small open spaces into neighborhood
entries.
• Provide linkages to the community paseo system.
• Shorten streets and provide curb-separated
sidewalks.
• Vary lot sizes where appropriate.
• Minimize visual impact of garages.
• Give attention to composition of building mass.
• Provide innovative plans and avoid repetitious
plans and footprints.
• Incorporate single-story elements in two-story
buildings.
• Vary setbacks at porches, living and garage areas.
• Incorporate single story elements in two story
buildings to minimize two-story dominance on
streetscene, sidewalks and open spaces.
• Step back second stories and vary roof planes.
• Design with sensitivity to corner lot conditions,
opening corner lots through selective plan form
and single story elements.
• Use appropriate transition of scale.
• Use four-sided elevation design.

The Director of Planning may administratively
approve modifications to the following standards up
to 15% for innovative and quality designs that meet
the intent of the provisions for this Specific Plan.

The following development standards shall apply
in all residential categories in the West Haven
Specific Plan area. Unless modified by the following
development standards, criteria contained in Sec.
9-1.1410 of the City of Ontario Development Code
shall apply.

8.3.2 General Elements
The general elements of building massing & plotting
include:
• Front Articulation
• Roof Form
• Garage Placement
• Balconies & Projections
• Rear Articulation
• Variable Setbacks & Lot Sizes
• Corner Lots & Critical Edge Conditions
1828
SECTION 8 • Design Guidelines
8-18 WEST HAVEN SPECIFIC PLAN

8.3.2(a) Front Articulation and Scale
Intent:

The front elevation of the home is an important
element in creating a quality community at West
Haven. Special attention will be placed on these
elevations and how they address the public realm.

Emphasis on location and design of entries, living
areas and garages will be to provide a special element
or “gift” to the street. Placing an emphasis on variety of building massing creates a diverse streetscene. Please
refer to Exhibit 8-11, “Front Façade Massing.”
Criteria:
• Building massing should be appropriate to
architectural style.
• Building details such as doors and windows should
be in proportion the overall building massing.
• All homes except American Colonial, Italianate
and Plantation style homes should have at least
three planes of variation in front elevation
massing; American Colonial, Italianate and
Plantation style homes should have at least two
planes of variation in front elevation massing.
• Porches and loggias shall be 4’ minimum in
cluster lots and attached homes, 6’ in depth
is preferred. Porches intended to meet usable
outdoor space requirements shall be a minimum
7’ depth, porch elements intended only as an
architectural enhancement may be less than
7’. 7’ minimum in depth and have an 8’ plate
height.
• Massing elements should project enough to avoid
elevations that appear to be “pasted on.”
• Building form is encouraged to reflect the interior
uses of the home.
• When appropriate to style, “recessed” two-story
elements are encouraged to create human scale
buildings.
• Front elevations with a single-story element for
two-story homes are encouraged.
• Front elevations are encouraged to emphasize the
placement of living areas, porches, covered terraces,
entries, and windows to address the neighborhood
street and other areas exposed to public view.

8.3.2(b) Roof Form
Intent:

Roof form is an important design element as it relates
to the character of the community, observed from
both the external edges and inside the neighborhood.

Variety of roof form along streets creates a positive
visual edge to these public ways. Appropriate massing
of roof forms help to create human scale architecture
to the street.

• Building form is encouraged to reflect the interior uses of the home. • When appropriate to style, “recessed” two-story
elements are encouraged to create human scale
buildings.
• Front elevations with a single-story element for
two-story homes are encouraged.
• Front elevations are encouraged to emphasize the
placement of living areas, porches, covered terraces, entries, and windows to address the neighborhood street and other areas exposed to public view.

8.3.2(b) Roof Form
Intent:

Roof form is an important design element as it relates
to the character of the community, observed from both
the external edges and inside the neighborhood.

Variety of roof form along streets creates a positive
visual edge to these public ways. Appropriate massing of roof forms help to create human scale architecture to the street.

Criteria:
• Roof forms shall reinforce the architectural style
of the home and shall be composed of a series of
simple roof forms.
• Roofs shall vary in massing along the streetscene
and open spaces.
• No more than three of the same main span roof
configurations (front to back or side to side framing) shall be adjacent to one another for variation in massing along the streetscene.
• Flat roof elements are encouraged only if appropriate to style. • Mainspan roof directional changes at narrower
lots are encouraged.
• Articulate the rear elevation and roof plane to
minimize the visual impact of repetitious flat
planes, similar building silhouettes and similar
ridge heights.
• Provide varied rear elevation roof forms when
those forms are exposed to public view.
• Gable end wall planes shall be a minimum of 12’
wide for lot sizes 50’ and wider.

8.3.2(c) Garage Placement
Intent:

The location, configuration and orientation of the
garage on its lot are important design elements, both
for the composition of the dwelling and its contribution to the streetscape.

De-emphasizing the garage is an important community design element. The goal is to design homesites to pull living portions of the house toward the front
of the lot to allow active, articulated architecture to address the streetscene.

SECTION 8 • Design Guidelines
WEST HAVEN SPECIFIC PLAN 8-19
• Flat roof elements are encouraged only if
appropriate to style.
• Mainspan roof directional changes at narrower
lots are encouraged.
• Articulate the rear elevation and roof plane to
minimize the visual impact of repetitious flat
planes, similar building silhouettes and similar
ridge heights.
• Provide varied rear elevation roof forms when
those forms are exposed to public view.
• Gable end wall planes shall be a minimum of 12’
wide for lot sizes 50’ and wider.

8.3.2(c) Garage Placement
Intent:

The location, configuration and orientation of
the garage on its lot are important design elements,
both for the composition of the dwelling and its
contribution to the streetscape.

Most plan variations should place entries, windows,
front porches and living areas directly adjacent to the street. Placing living areas forward encourages “eyes
on the street” for neighborhood safety and security
while establishing neighborhood orientation to the
pedestrian as opposed to the automobile.

To mitigate the negative impact of garages on the
fronts of homes, each planning area is encouraged
to incorporate a variety of the alternative garage
placement configurations described below. (Where
higher density neighborhoods are incapable of
achieving these standards they shall incorporate those
aspects that are practical and applicable.)
• Garage Forward
• Shallow Recessed Garage
• Mid-Recessed Garage
• Deep Recessed Garage
• Offset Garage
• Tandem Garage
• Swing-in Garage
• Rear-Loaded Garage
• Mansion Corner Lot Garages
Criteria:
• At least 75% of front accessed homes shall have
“architecture forward” standards; no more than
25% of homes in any neighborhood area shall have
street facing garages set back closer to the street
than the living area (side loaded garages exempted
from this ratio). To qualify as “architecture
forward” the garage door plane must be set back
from the forwardmost living area façade at least 5’.
• Garage door plane will vary at least 2’ from the
adjacent living area façade.
• Minimum interior garage dimensions for two-car
side-by-side configuration is 20’ x 20’ clear, one
step may encroach, but water heaters may not
encroach into this area.
• Garage door patterns are encouraged to vary among
elevation types and to reinforce the architectural
theme of the dwelling.
• A minimum 2’ offset is required where garages are
adjacent on common property lines.
• 3-car side-by-side garage configurations are
discouraged and are limited to a maximum of 25%
of homes in any neighborhood; at least one garage
door must be offset from the others 2’ minimum.
• Garage door recess is encouraged to be a minimum
of 8” from parallel walls.
• In front loaded garage homes, minimum driveway
length from garage door shall be 18’ from back of
sidewalk.

setback shall be 3’ with a 5’ average setback for
second story elements over the garage.
• Alleys serving as access ways to residential
parking facilities shall be designed in accordance
with the following standards. At minimum, the
alleys shall provide 30 feet of back up area as
measured from the garage face.
• A minimum 24’ clearance is required at all times
along the length of the alley; on both sides of the
alley, between each garage (approximately every
30 feet), a landscaped planter shall be installed
and shall project 3’ beyond the face of the garage
toward the alley.

Examples of Garage Orientation Types
(Please refer to Exhibit 8-12, “Garage Placement
Alternatives”):

Garage Forward
When garages are forward of the porch or front
facing building elevation, a minimum driveway
length of 20-feet shall be maintained from back
of sidewalk (property line) to face of garage
door. Garage forward configuration shall be
limited to no more than 25% of the total number
of units in a builder’s plan package.

Shallow Recessed Garage
Set the garage back a minimum of 2’ from
the adjacent living space façade of the house
(excluding porches). This setback strives to
reduce the overall visual mass of the garage.

Mid-Recessed Garage
Set the garage back at the mid-point of the home
to exposes more highly articulated, habitable
architecture toward the street while the garage
remains attached to the house is achievable in
lower density neighborhoods.

Deep Recessed Garage with Porte-Cochere
Set the garage back to the rear of the lot. This

Tandem Garage
This garage layout de-emphasizes a third garage
space by concealing it behind a standard twocar side-by-side garage condition, permitting the tandem space to option into living space while
still only showing the original two car garage
to the street. This garage configuration can be
shallow, mid-recessed or deep recessed garage
design, however it is typically either shallow or
mid recessed into the lot so as to be incorporated
into the architecture of the home.

Garage with Casita
This garage layout breaks up the massing of the
two-car garage by offsetting two one-car garages

Swing-in Garage
A single or two-car swing in garage may be used
on a lot with a minimum width of 50’ to break
the continuous view of garage doors along a
streetscene, allowing a more formal motorcourt
entrance. Although not mandatory, a 60’ wide lot
provides for optimal configuration. Side entry
garage conditions also allow a reduction in the
required front setback as well as greater variation
in the streetscene. The elevation facing the
street shall have an architectural detail such as a
window, reveal or pop-out.

A minimum 24’ back up space is required; note
that lots providing less than 24’ feet of backup
maneuvering room are subject to City approval of
the alternative design standards.

Rear Accessed Garage
Garages may be concealed by detaching and
locating them to the rear of the lot. Garage
accessways may be relocated off neighborhood
streets to promote a more traditional,
pedestrianfriendly streetscene. Garages accessed
from an alley create a more traditional streetscene,
without garages visible at the front side of the
home. Recess garage door a minimum of 8” on
alleyloaded garages.

Mansion Corner Lot Garages
Having entry doors on the front elevation while
the garage doors are located on a side elevation,
mansion corner lot garages are plan forms that
allow architectural enhancements to wrap around
the home from front to side elevations. Corner
lot garages may be addressed two ways; plans
may be designed for corner orientation or interior
lot plans may be adjusted to address corner
conditions. The purpose of either solution should
be to create substantial streetscene variation while
the architecture wraps the exterior lot frontage.

When a garage faces onto the street side, it shall be
setback a minimum of 18 feet as measured from
property line.

8.3.2(d) Balconies & Projections
Intent:

As part of the overall composition of a two-story
dwelling, balconies or projections provide relief
and interest at the second story. Additionally, these
elements create ideal outdoor rooms.

Criteria:
• Balconies shall be roofed when they exceed 4’ in
depth.
• Balconies and projections shall proportionally
complement and be integrated into the overall
massing of the home.
• Balconies shall not be located at outside edges of
homes where they can overlook private spaces of
adjacent homes.
• Balcony railings are encouraged to be consistent
with the architectural style.
1832
SECTION 8 • Design Guidelines
8-22 WEST HAVEN SPECIFIC PLAN
• Architectural projections such as media niches
and chimneys are encouraged to be a maximum
of 3’.
• Covered balconies and living area cantilevers are
encouraged to be appropriate to the architectural
style.
• Opportunities for creating shaded areas and
usable outdoor spaces are encouraged.
• Multiple balcony options should be considered
based of effective solar orientation.
• Metal awnings are prohibited. Fabric awnings of
solid accent colors are permitted in moderation.

8.3.2(e) Rear Articulation
Intent:

Particular attention will be placed on the design of
those dwellings adjacent to or in close proximity of
major community roadways, open spaces, or entry
features. Whether viewed from distant or close range,
massing requirements will be implemented to ensure
positive community character in these locations.

Generally, repetitious elements such as continuous
gable ends and similar building silhouettes shall be
avoided.

Criteria:
• Plans shall utilize projections and/or offsets that
extend from the main wall plane.
• The stepping or use of projections on rear facades
is encouraged to create the articulated massing
important to the character of the community.
• Homes directly adjacent to arterial roadways,
collector roads, entry drives, and open spaces
are encouraged to be given particular attention in
their rear articulation, contributing positively to
these edges.
• Building forms that are assemblies of interlocking
masses are encouraged.
• Architectural massing and articulation appropriate
to style is encouraged.
• Vertical and horizontal plane breaks are
encouraged.

8.3.2(f) Variable Setbacks & Lot Sizes
Intent:

The key to quality neighborhood design is the emphasis
on the “living” areas of the home orienting toward
the street. To encourage this, reduced setbacks are
allowed for living areas as measured from the back of
walk. Additionally, variable front and rear setbacks
for both living and garages are encouraged (and
mandated through entitlement) to create diversity in
streetscenes. Finally, vary lot sizes to increase buyer selection and variety in house and house and lot size
combinations, where appropriate.

Criteria:
• Setbacks shall be appropriate and proportionate to
the housing type and lot size.
• Variable rear setbacks are encouraged to create
variety for edge conditions such as homes
backing to collector roads and back-to-back
homes on alleys.
• Monotonous repetition resulting from strict
1833
SECTION 8 • Design Guidelines
WEST HAVEN SPECIFIC PLAN 8-23
compliance to the minimum garage setbacks
should be avoided.
• Variations in lot widths may be matched to floor
plans so long as the average lot size specified for
the product type is maintained.
• The minimum lot width for a flag lot, cul-de-sac,
or knuckle at front property line may be reduced
five feet (5’) from standards. Lots at the end
of cul-de-sacs and knuckles may vary from
the minimum depth requirement provided a lot
provides an adequate area for development.

8.3.2(g) Corner Lots & Critical Neighborhood
Edge Conditions
Intent:

Single-story elements at corner conditions should
be considered in West Haven. Creating a “human
scale” edge utilizing single-story elements and other
architectural details provide optimal massing forms
oriented to pedestrians. Porches that wrap around
two sides of the house provide a transition from the
public realm of the street to the private home.

The continuous overly “walled” appearance along
neighborhood perimeter streets may be avoided
through special treatments in selected locations.

Please refer to Exhibit 8-13, “Neighborhood Edge
Treatments.” Possible treatments may include
incorporation of hedges and neighborhood street
tree programs in a conventional format (Option 1),
and side on courtyards with open cul-de-sacs and
trail connections (Option 2), view fencing, etc. These
treatments will be consistent with Exhibit 8-31,
“Community Walls & Fences - Locations” and 8-32,
“Community Walls & Fences - Details.”
EXHIBIT 8-13: NEIGHBORHOOD EDGE

W E S T H AV E N S P E C I F I C P L A N 8-23
• Corner homes shall have single story elements at
corner edges.

8.3.3 Fronting on Parks, Paseos &
Parkways
Homes fronting onto parks and greenbelts activate
the open spaces as well as add a sense of security.

Intent:

Neighborhood layouts shall provide connections into
the community paseo system to encourage pedestrian
flow through the project.

Please refer to Exhibit 8-14, “Open Space
Walkways.”
Criteria:
• Encourage integrating small open spaces into
neighborhood entries.
• Possible linkage treatments may include dedicated walkways (Option 1) or shared walkways with access to front doors (Option 2).

8.4 Residential Building Materials
& Details
Strong architectural detailing is a key element to
creating quality communities. During the design of
West Haven, special attention has been given to the
details of the homes. Appropriated focus should also
be given to the design of the secondary elements of
the architecture.

8.5 Simple Home Design
Introduction
As a guide to designers and home builders, the
following section has been developed to aid in the
implementation of the aforementioned design criteria.

As stated, the primary goal of the community developer
is to balance the desire to create quality neighborhoods and homes within the realities of construction
methodologies and target costs. By emphasizing the
simple massing and structural forms of the home,
costs may be reallocated to more authentic detailing
and finishes. These elements of simple home design
are intended to be used as tools to achieve hard cost
budgets.

Elements of Simple Home Design
• Create a simple series of small span boxes when
designing the floor plan.
• Reduce the number of truss spans for a given
project by utilizing the same truss span in a
number of locations throughout the project. This
reduces the cost for the truss package on the
project.
• Use ½ truss spans for the porches rather than using
a new span and truss type.
• Use “shell construction” in one-story houses and
eliminate three-point bearing trusses and interior
bearing walls and trusses.
• Use girder trusses instead of interior bearing
walls and footings.
• Eliminate “scissor” trusses and use flat ceilings
instead. (Scissor profiles in short span trusses are
economically inefficient.)
• Reduce window schedules to fewer sizes than
usual. Utilize same window sizes in multiple
locations. Traditional architectural vernaculars
are best designed with a simple methodology in
selecting window sizes and proportions.
• Keep windowsills a minimum of 18” from finish
floor, eliminating the need for tempered glass.
• All ceiling heights should conform to Gypsum
board Modules (8’-1”, 9’-1”, 10’-1”, 12’-1”).
• Show schedules for substitute beams at all locations
so that paralam, Glulam, MicroLam, or dimensional
lumber can be used.
• Design stair plans with straight legs, rather than
curved forms.
• Develop a methodology utilizing a concise variety
of modular pieces in kitchens, baths, and utility
rooms with standardized cabinet modules.

8.6 Nonresidential Architectural
Design Guidelines

8.6.1 Introduction
Situated at the intersection of Haven Avenue and
Riverside Drive, West Haven’s primary entry point,
the Neighborhood Center commercial land use
area presents a unique opportunity to establish an
appropriate and unifying theme to reinforce district
identity. Likewise, the visibility and scale of the
Elementary School located on Haven Avenue, south
of Chino Avenue, will establish West Haven’s district
identity as well as dominate the district’s architectural hierarchy. Thoughtful planning and design
coordination of these two important community
components will assure the goal of high design quality
for West Haven will be achieved.

Neighborhood Commercial center and Elementary
School developments present certain architectural
opportunities and limitations due to building massing,
parking requirements, pedestrian and service access,
lighting, etc., that require master planning prior to any land subdivision or development in order to ensure
the integrated development of Planning Areas 2 and
7 within the West Haven community. Therefore, this
section provides a standard set of concepts, goals and
criteria for Nonresidential architectural design that
builders will use to achieve the goal of quality design.

The objective is to create attractive Neighborhood

environments that are related in scale and aesthetic to the entire West Haven development.

Please refer to Exhibit 8-15, “Neighborhood
Commercial Center and E l e m e n t a r y
School Concepts.”
The following is a list of additional criteria, which
apply to this land use area. It should be noted that
site design and architectural standards not specified
within this section shall be subject to the City’s
Design Guidelines and Performance Standards (City
of Ontario Development Code Article 16: Commercial
and Professional Districts) and the Uniform Building
Code. The West Haven Specific Plan takes
precedence over regulations in the Development
Code.

8.6.2 Siting and Orientation
Intent:
• Buildings shall be designed using simple local
historic forms integrated with public spaces and
landscape elements that reinforce their functions
as a community gathering places and architectural
focal points for the West Haven community.
• All design shall incorporate the combination of
compatible architecture and landscape forms to
ensure that these developments achieve an image
that is positively differentiated as distinctive,
clearly understandable and unified.
• All designs shall appear as an integrated part of
an overall design concept as well as including
logical connections to adjacent uses.
• To unify the site, use common site design
elements such as lighting and signage, enriched
paving, and landscape treatments.
• Site design shall incorporate variations in
elevations.
• Buildings shall be arranged, where possible, to
create a variety of outdoor spaces (courts, eating
areas, usable open space, etc.) large enough to be
usable but not so large as to appear empty.
• Building units shall vary in orientation and
be dispersed throughout the site to reduce the
impact of development on neighboring residential
areas.

8.6.3 Access and Parking Facilities
Criteria:
• On-site parking facilities should be shared to
minimize curb cuts.
• Use enhanced paving to announce vehicular
entries; their treatment and color should
complement the building architecture and overall
site design. Enhanced paving is to remain on
private property.
• Vehicular and pedestrian circulation routes shall
be well separated and defined by landscape and
site design elements.
• Visitor parking shall be located in close proximity
to main entrances. Employee parking and loading
zones shall be located to the side or rear of the
buildings and attractively screened from public
streets with landscaping or other site design
elements.
• Screen on-site parking facilities from the street
and adjacent residential uses. A combination
of extensive plantings and decorative boundary
walls should block views from and buffer
adjacent residential properties; shrubs, earth
berming, and/or low, decorative screen walls are
recommended to screen views of parking facilities
from the street.
• Mitigate the expansiveness of surface parking
lots; shade trees and other plants should be
provided within parking areas to enhance their
appearance, reduce heat build-up, and help
regulate storm water runoff.
• Illuminate parking areas for added security;
however, security lighting should be consistent
with the design character of the site, and directed
and shielded to avoid impacts and minimize glare
on neighboring residential uses.

8.6.4 Service Facilities
Intent:
• Locate service, loading and storage facilities
away from public streets and outdoor spaces.

As far as is feasible, these facilities should be
unobtrusive and not sited as an afterthought.
• Screen impacts and views of service, loading and
1841
SECTION 8 • Design Guidelines
WEST HAVEN SPECIFIC PLAN 8-31
storage facilities from streets, outdoor spaces, and
adjacent residential uses; appropriate screening
strategies include compatible architectural
treatment or decorative walls with complementary
landscape. As far as feasible, these facilities
should also be attractively screened from direct
views from parking areas. Similarly screen
utility transformer boxes placed within yard areas
adjacent to a street and/or the public right-of-way.
• Introduce refuse enclosures and equipment as
an integral part of the site design, including
provisions for easy access by service vehicles.

These facilities should be located within a
screened enclosure built of high quality materials
that reflect the architectural style of the building.

Enclosures shall be constructed to comply with
all requirements as set forth by the City’s Water
Quality Division.

8.6.5 Form, Scale and Massing
Intent:
• Buildings shall be designed with well-articulated
elevations and with openings and entries that are
clearly defined.
• Scale (particularly for a supermarket if provided
in the Neighborhood Commercial center)
should be given careful consideration. Long,
uninterrupted expanses of walls shall not be
allowed.
• Employ simple, yet varied massing, with deep
wall openings that create shadow lines and
provide visual relief.
• Interconnection and lapping of building forms
and heights, to break up long expanses of blank
walls, help relieve monotony and are desirable.

Criteria:
• All building sides should be considered equally;
the architectural concept must be consistent on all
sides. Buildings may not have a special treatment
only on the façade facing the street.
• Development of special design character at
building entrances is required.
• Use fenestration, as well as changes in wall plane,
material, texture, color, etc., to create shadow
lines and articulate building walls.
• Extensive blank wall surfaces are not allowed,
especially along sidewalks, outdoor spaces, and
heavily trafficked areas.
• Used brick or used brick appearance is not
acceptable. Exposed standard concrete block is
not permitted as a finish material.
• Corrugated metal siding and metal panel wall
systems are not acceptable.
• Exposed plywood sheathing is not acceptable.

8.6.6 Architectural Styles and Features
Intent.
• Promote architectural design that fits with and
enhances its surroundings, emphasizing visually
attractive buildings that bring interest to the street
and add richness and variety to the community.
• Encourage compatibility between commercial,
institutional and residential architecture within the
Specific Plan area; the introduction of unifying
elements such as common materials and colors
should be considered.
• Building facades shall be based upon a pleasing
set of proportions and a clear pattern of building
openings.
• Fixtures and finishes should be selected for
their contribution to the overall theme of the
development.
• Require a high degree of street level transparency,
especially along sidewalks, important outdoor
spaces, and heavily trafficked areas.
1842
SECTION 8 • Design Guidelines
8-32 WEST HAVEN SPECIFIC PLAN
Criteria:
• All buildings and structures shall comply with
the applicable provisions of the City-wide Design
Guidelines.
• American Farmhouse and Spanish architectural
styles are designated styles for Planning Area
2 buildings, and American Farmhouse or
Craftsman architectural styles are designated
alternative thematic styles for Planning Area 7
buildings. (Refer to Section 8.2.3, “West Haven
Architectural Styles” for American Farmhouse,
Craftsman, and Spanish style descriptions.)

• Orient signs away from neighboring residences.
• Establish a hierarchy of illumination levels based
on design intent; for example, the illumination of
entry monumentation is highly encouraged.
• Require signs that are in balance and scaled to
the building, site and surrounding area; avoid
repetitive signage and visual clutter on a building
frontage.
• Design monument signs to complement the
building architecture and the streetscape;
colors and materials should be consistent with
the structures on site and enhance landscape
elements.
• Design tenant identification signs to fit
comfortably with the storefront architecture; wall
signs and pedestrian-oriented signage should
not obscure architectural features and should be
incorporated as an integral part of the building
façade.
• Establish a coordinated sign program to
accommodate multiple tenants; a commercial
development’s signs, including tenant
identification signs, should complement, but not
necessarily replicate the style of one another.
• Offer a clear, simple message; the number of
lettering styles should be limited, and the use of
identifiable symbols and logos is encouraged.
• Encourage external sign illumination using
unobtrusive, yet attractive fixtures; this often
permits better integration of wall sign and façade,
although fixtures should not obscure the graphic
of the sign.
• Provide sufficient lighting to ensure the safety
and well being of the community; in addition,
outdoor lighting should visually enhance
the project by highlighting and accentuating
architectural or landscape features.

Criteria:

The following are appropriate to West Haven:
• Orient signs away from neighboring residences.
• Construct high quality signs with durable materials;
individual channel letters are encouraged for wall
signs.

consistent in style, color and materials, maintaining
uniformity throughout the project.
• Locate and direct outdoor lighting (including
security lighting) to avoid unwanted glare and
minimize impacts on neighboring residential uses.
• Encourage subtle lighting that provides a soft
wash of light over illuminated objects.
• Encourage low, shielded walkway lighting.

8.7 Landscape Architecture

8.7.1 Landscape Description
This Section is general in scope. More detailed
landscape concepts will be illustrated in the Landscape Design Guidelines section of this document, Section

8.8 “Landscape Design Guidelines.”
Landscaping will be used to identify the hierarchy
of the street system, distinguishing perimeter master
planned roads and residential streets. Landscaping
will be successfully implemented through the use
of varying landscape materials, texture and color, to
enhance the image of the West Haven Community.

Entry monument features at major intersections will
provide the initial impression of the West Haven
development, when approached via Haven Avenue and
Riverside Drive. The project’s entry monumentation
will be developed in a hierarchy format to include
Major Community Entries, Secondary Community
Entries, and Neighborhood Entries, which will
identify each residential planning area.

8.8 Landscape Design Guidelines

8.8.1 Introduction

8.8.1(a) Landscape Concept
The West Haven community is a part of the overall
New Model Colony Ontario Ranch Master Planned
Community in the City of Ontario. The planning
concepts for the West Haven Specific Plan are
implemented in several ways; implementing the
New Model Colony Ontario Ranch vision for
perimeter streets, creating a walkable pedestrian
friendly environment and creating community spaces
that allow people to gather and circulate through
the community on one of the near by pedestrian
paseos. Implementing the features of the West Haven
Landscape Plan is the primary means of translating
landscape themes and ideas into the community. See
Exhibit 8-16, “Conceptual Landscape Plan” for
further details.

8.8.1(b) Pedestrian Environment
The West Haven Specific Plan creates pedestrian
connections through paseos and safe, pleasant
streetscapes. Residents of West Haven may walk
from home to adjoining neighborhoods, to scattered
community pocket parks, and to the Neighborhood
Park, frequently without crossing a street. This paseo
system enables those who do not drive to have access
to homes of friends and those community facilities
they use most. Benches located at key intersections
and along paseos provide rest stops and places for
neighbors to visit.

8.8.1(c) Recreation
A five (5) acre net Neighborhood Park will be built in
Planning Area 8 and will include activities for children as well as adults. This park will be located adjacent to the SCE Easement and is surrounded by streets on two
(2) sides and a pedestrian paseo on one (1) side.

Pocket parks are programmed to include passive uses as
well as child and adult active uses. Some pocket parks
are planned within the neighborhood, while others are
located in Planning Area 1 are within or adjacent to
the Gas Company easement. Please refer to Section

8.9.3 “Community Connections and Recreation”
which further describes community connections and
recreation. The pocket park requirement for West
Haven is 2 acres/250 units, with a minimum size of
10,890 square feet (1/4 acre).

8.8.1(d)Design Elements
Landscape design elements, are included in both
landscape and structural features and occur at both
community and neighborhood levels. They serve
to establish and reinforce the design theme for
West Haven. These elements include community
monuments at entry points, community walls and
fences, creation of streetscenes through street design, median and neighborhood edge parkway landscapes
and the relationship of the paseo and paseo system
to recreational elements and homes. The community
neighborhood park, pocket parks and paseos will be
accessible to the public and will be maintained by a
Homeowners Association, the SCE Easement paseo
and linear park will also be accessible to the public and will be City (LMD CFD) maintained. The Landscape
Guidelines compliment the Architectural Guidelines,
and together they define the ambiance of the West
Haven Community.

8.8.2 Community and Neighborhood
Streetscenes
The community streetscenes implement the planting
and hardscape theme for each backbone street as
described in the New Model Colony Streetscene
Master Plan document, and as adopted by the City of
Ontario.

The landscape treatment, referred to as Neighborhood
Edges, for master planned roadways are designed

to create an open, expansive feel with the use of
generous streetscene panels on all backbone streets
surrounding the West Haven Specific Plan.

The landscaped Neighborhood Edges vary in width
from 30 feet to 45 feet, depending on the street, as
described in the following streetscene sections.

8.8.2(a) Riverside Drive – Neighborhood Center
Commercial Edge
Riverside Drive is adjacent to both Residential
and Commercial (neighborhood center) land uses.

The landscape development associated with the
Commercial (neighborhood center) is illustrated
in Exhibit 8-17, “Riverside Drive Streetscene
at Neighborhood Center Commercial,” which is
consistent with the New Model Colony Streetscape
Master Plan, or as adopted by the City of Ontario.

This streetscene consists of:
• 7’ wide curbside landscaping planted with shrubs
and groundcover or turf, as adopted by the City
of Ontario.
• 5’ wide sidewalk parallel with the street within
the 12’ wide street parkway
• 23’ wide shrub zone between the sidewalk and
the commercial development

8.9.2 Walls and Fences - Introduction
Walls and fences that are used throughout West
Haven Specific Plan provide streetscene theming
and delineate property boundaries. (See Exhibit
831, “Community Walls and Fences—Locations,”
Exhibit 8-32, “Community Walls and Fences—
Details” and Exhibit 8-33 Community Wall Plan.)

8.9.2(a) Residential Fencing
General guidelines for use of residential walls and
fences are provided below:
• 6’ high walls are used to provide privacy for all
homes.
• Since West Haven is a flat site, there is not
opportunity for the use of any view fencing.
• The block wall along all perimeter edges and
between residential units shall be constructed of
‘Mission’ slump block (or other decorative block)
with solid masonry cap. Wall grout shall match
block color. (See Exhibit 8-32, “Community
Walls and Fences—Details” and Exhibit 8-33
“Community Wall Plan.”)
• A 6’ high block wall or wrought iron fence shall
be used at all residential side yards, rear yards and
front yard between house fencing.
• Front yard fencing higher than thirty inches
(30”) high shall not extend into the front yard
beyond the front elevations of the house. No
walls or fences may be erected within the street
right-of-way.
• All walls and fencing shall conform to applicable
State of California and City of Ontario pool
codes, whichever is more stringent.

8.9.2(b) Neighborhood Center Fencing
General guidelines for walls and screening of service
areas are provided below:
• Trash deposit areas shall be enclosed by a 6’
minimum height solid wall with service gate. All
trash enclosures are to be located out of public
view.
• Perimeter walls are allowed on the side and
rear of the commercial site and shall match
the community solid wall. The wall shall be
constructed of ‘mission’ slump block with solid
masonry cap.
• No walls are permitted beyond the front elevation
of the commercial building.
• No wood fence, chain link fence, wire fences,
plain concrete block walls or grapestake fence is
allowed.

8.9.3 Community Connections and
Recreation
Exhibit 8-16, “West Haven Conceptual Landscape
Plan” illustrates the location of the 5-acre
Neighborhood Park, pocket parks and paseos.

8.9.3(a) Five-Acre Neighborhood Park
Typically, 5 acre net Neighborhood Parks are located
adjacent to elementary schools, however, many
school districts today, for security purposes, do not
favor this arrangement. Most School Districts prefer
that the park not be located directly adjacent to the
school, and if they are, typically there would be a
fence or wall between the two. For these reasons,
the Five-Acre Neighborhood Park is located across
the street, but within close proximity to the school in Planning Area 8. The park and the elementary do not
share play fields or other facilities. (See Exhibit 8-34, “Five-Acre Neighborhood Park Concept Plan.”)
The Neighborhood Park which shall be accessible to
the public, is located with two (2) streets adjacent to the park and also located next to the SCE Easement
paseo system and a pedestrian paseo within Planning
Area 8 on the other two (2) sides. The park design
shall include entry points from each street as well as
from the Planning Area 8 paseo, the SCE Easement
Linear Park. The neighborhood park shall include the
following:
• 80% level (minimum).
• Sports field shall consist of hybrid Bermuda seed
mixture.

8-80 WEST HAVEN SPECIFIC PLAN
• Irrigated with reclaimed water, per City Standard
Specifications.
• Tot lot area shall be constructed using a majority
of synthetic safety surface per ADA, with wood
fiber used in some areas.
• Tot lot shall contain separate play areas for
younger children (2 to 5 years old) and an area for
older children (5 to 12 years old).
• All trees and shrubs to be selected from Table 81
“Community Plant Matrix” or as adopted by the
City of Ontario.
• Large deciduous canopy trees to be used
immediately adjacent (south and west sides) to
benches, seating areas and play equipment areas to
provide shade in the summer.

The park features shall include the following:
• Children’s Play Area (Tot Lot)
• Sports Field
• Family Picnic with Braziers
• Drinking Fountain
• Public Restrooms
• Parking Lot
• Concrete Walkways/Jogging Trail
• Open Turf Areas
• Drinking Fountain
• Benches
• Trash Receptacles
• Bicycle Parking Area
• Shade (Picnic Shelter)
• Lighting
• The Neighborhood Park is installed by West
Haven Builders and shall be HOA maintained.

8.9.3(b) Community Connections
One primary design element demonstrated in the West
Haven Specific Plan is the principle that communities
should support pedestrian movement. This goal is
achieved in several ways. First, all streets include a
sidewalk or paseo system that is separated from the
street by a parkway. Second, greenbelts and pedestrian
paseos meander through the Southern California
Edison (SCE) easement and the gas company easement
serve to connect neighborhoods to each other and to
other community elements.

Sidewalks along the community’s backbone streets
are separated from vehicular travel by a landscaped
parkway. The sidewalks along local neighborhood
streets are 5’ feet wide with a 7’ foot wide curbside
landscaping zone. These parkway widths have been
planned to accommodate appropriate street tree
planting with concern for or taking into account the
health of trees or destruction of the sidewalk by tree
roots. Linear tree root barriers shall be installed
adjacent to the edge of sidewalks and curbs when a
tree is planted closer than five feet (5’) to a curb or sidewalk.

To further encourage walking in the community a
series of greenbelt paseos are planned and continue
throughout the community.

8.9.3(c) SCE Easement Paseo and Linear Parks
Paseos within the SCE easement shall be accessible
to the public, and serve as the primary pedestrian
circulation system throughout the West Haven
community. The developer shall be responsible
for the construction of paseo and linear park usage
on their property for the area on which they have
underlying ownership. Paseo connections to
neighborhoods are planned to allow residents easy
access to the paseo system. Additionally, park uses
are planned within the easement to allow those
utilizing the SCE paseo system opportunities to
better utilize the space. Trees, with a maximum
height of fifteen feet (15’) are allowed within the
SCE easement, as well as drought tolerant and native
shrubs. The SCE Easement paseo and linear parks
within the easement feature the following: (Refer
to Exhibit 8-35, “SCE Easement Paseo and Linear
Park Plan View” and Exhibit 8-36, “SCE Easement
Paseo and Linear Park Section.”)
• A total of a 30’ wide paseo and linear park
development zone within the SCE Easement.
• 10’ wide meandering asphalt or decomposed
granite paseo (meanders within the 30’ wide
development zone).
• Benches.

Ontario.
• Bubbler irrigation. (No drip or spray irrigation
allowed in the SCE Easement).
• Par stations along the paseo.
• Neighborhood connections to the SCE Easement
paseo system.
• All remaining areas within the SCE Easement
not within the 30’ wide Park Development Zone
shall receive ‘weed control’ as part of on-going
Southern California Edison maintenance.
• All improvements within the SCE easement are to
be implemented by the Builder and are City (LMD
CFD) maintained.
• Final Development Plans within the easement
require Southern California Edison approval.
• Trees, 15’ feet in height (maximum) are allowed
within the SCE Easement.
• Notes:
1) No lighting is allowed within the SCE
Easement.
2) No irrigation controllers or main line allowed
within the SCE Easement.
3) Irrigation lateral lines and bubbler irrigation
heads are the irrigation equipment allowed
with the easement.
4) No trees over fifteen feet (15’) in height are
allowed within the easement.

8.9.3(d) Gas Company Easement/Pocket Parks
A 30’ wide existing gas company easement lies within
Residential Planning Area 1. Pocket parks are a gas
company approved use within their easement. Six foot
(6’) high community walls (except at wall returns) will be utilized at the edge of the easement at residential
rear and side yards that are adjacent to the easement.

Final lot plotting and wall locations will be further
refined during the preparation of the Tentative Map. A
ten foot (10’) wide service road/pedestrian walkway
meanders through the easement with pedestrian
walkway connections at neighborhood streets.

Pedestrian connections to the SCE easement trail, as
well as a pedestrian walkway connection to adjacent
neighborhood center will be accommodated. The
pocket parks within and adjacent to the gas company
easement shall be accessible to the public, and feature the following: (Refer to Exhibit 8-37, “Typical Pocket
Park within Gas Company Easement” and Exhibit
8-38, “Gas Easement/Pocket Park Edge”).
• 30’ wide easement.
• 10’ wide asphalt meandering service road/
pedestrian walkway and jogging trail. Walkway
no closer than 10’ to a residential rear or side yard
wall.
• Passive park uses.
• Benches
• Turf open play areas.
• 6’ high community wall at residential property
lines.
• Shrub buffer along residential property lines.
• No deep rooted trees, select from Table 8-1,
“Community Plant Matrix” or as adopted by the
City of Ontario.
• Walkway connections to SCE easement trail
system.
• Walkway connection to the neighborhood center
planned for Planning Area 2.
• No tree (ultimate drip line) shall be any closer
than 10’ to the gas line.
• All improvements within the gas company
easement shall be made by the Planning Area
build
er in which they fall, and shall be professionally
maintained by the HOA.
• Final development plans within the gas company
easement require gas company approval.
• Gas Company easement pocket parks shall count
towards required pocket park acreage.

8.9.3(e) Pocket Parks
As indicated in the City of Ontario New Model
Colony General Plan Amendment, the formula for
determining acreage for Pocket Parks indicates for
every 250 dwelling units, 2 acres of pocket parks are
required. The size and location of the neighborhood
pocket parks vary depending on the location and
acreage required. As each residential neighborhood
is designed, the final acreage, configuration and final 1894

locations of pocket parks will be determined. The
pocket parks shall be accessible to the public, and
shall be built by the West Haven Builders and shall be
maintained by the HOA.

These pocket parks create open spaces where
neighbors can visit near their homes. Depending on
the intended use, the design of these parks will vary.

Some may include tot lot and open play spaces for
young children. Some may include facilities designed
for more active adults, such as a multi-purpose sports
park. Others may contain more passive spaces with
gardens, seating areas, walkways and open turf areas.

Generally, parks planned within a residential parcel
should be designed to front on three (3) neighborhood
streets. Three possible examples are illustrated in
Exhibit 8-39, “Typical Child Active Pocket Park,”
Exhibit 8-40, “Typical Passive Pocket Park” and
Exhibit 8-41, “Typical Adult Active Pocket Park.”
These are very general in nature and should not be
interpreted as design plans.

Some pocket parks, at City discretion, may be located
within the Gas Company easement within Planning
Area 1. This park counts toward, and more than
satisfies, the pocket park acreage required for that
planning area. The total acreage for the Gas Company
easement and all pocket park totals approximately
