6. Climate Risk Detailed Report

6.1. Climate Risk Summary
Cal-Adapt midcentury 2040–2059 average projections for four hazards are reported below for your project location. These are under Representation Concentration Pathway (RCP) 8.5 which assumes GHG emissions will continue to rise strongly through 2050 and then plateau around 2100.

Temperature and Extreme Heat data are for grid cell in which your project are located. The projection is based on the 98th historical percentile of daily maximum/minimum temperatures from observed historical data (32 climate model ensemble from Cal-Adapt, 2040–2059 average under RCP 8.5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Extreme Precipitation data are for the grid cell in which your project are located. The threshold of 20 mm is equivalent to about ¾ an inch of rain, which would be light to moderate rainfall if received over a full day or heavy rain if received over a period of 2 to 4 hours. Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

Sea Level Rise data are for the grid cell in which your project are located. The projections are from Radke et al. (2017), as reported in Cal-Adapt (Radke et al., 2017, CEC-500-2017-008), and consider inundation location and depth for the San Francisco Bay, the Sacramento-San Joaquin River Delta and California coast resulting different increments of sea level rise coupled with extreme storm events.

Users may select from four scenarios to view the range in potential inundation depth for the grid cell. The four scenarios are: No rise, 0.5 meter, 1.0 meter, 1.41 meters 87 / 93

Coronado HEU - Unit Net Increase Detailed Report, 1/2/2024 Attachment 9
Wildfire data are for the grid cell in which your project are located. The projections are from UC Davis, as reported in Cal-Adapt (2040–2059 average under RCP 8.5), and consider historical data of climate, vegetation, population density, and large (> 400 ha) fire history. Users may select from four model simulations to view the range in potential wildfire probabilities for the grid cell. The four simulations make different assumptions about expected rainfall and temperature are: Warmer/drier (HadGEM2-ES), Cooler/wetter (CNRM-CM5), Average conditions (CanESM2), Range of different rainfall and temperature possibilities (MIROC5). Each grid cell is 6 kilometers (km) by 6 km, or 3.7 miles (mi) by 3.7 mi.

NOISE TECHNICAL

MEMORANDUM
To: Richard Grunow, Director, Community Development, Redevelopment Services and Housing, City of Coronado
From: Sharon Toland, Senior Technical Specialist, and Kelsey Hawkins, Noise Technical Analyst, Harris & Associates
RE: Analysis of Permanent Vehicle Noise Impacts for the 6th Cycle 2021–2029 Housing Element Update Date: February 16, 2024
CC:

Att:

Ryan Binns, Senior Director, Environmental + Planning Consulting, Harris & Associates 1, FHWA Noise Prediction Model Results
Introduction
This memorandum provides the results of Harris & Associates’ analysis of the potential vehicle noise impacts from implementation of the 6th Cycle 2021–2029 Housing Element Update (HEU or project). The effort would include amendments to the Coronado General Plan land use designations and City of Coronado (City) zoning designation for consistency with the HEU. The HEU would be consistent with existing state law and outlines the implementation plan of the City’s goals, policies, quantified objectives, and programs for the preservation, improvement, and development of housing for a sustainable future. Potential impacts of the Coronado General Plan land use designation and zoning changes have not yet been evaluated. Therefore, this analysis focuses on the land use designation and zoning changes in the HEU.

The City is on a narrow peninsula of land at the southwestern edge of the San Diego region. It is bounded by the Pacific Ocean to the west and the San Diego Bay to the east. The City is accessible by the 2-mile-long San Diego– Coronado Bridge from the east and State Route 75 from the south. The project area includes 10 opportunity sites throughout the City. Each opportunity site is assigned a number (e.g., Opportunity Site 1). Opportunity Sites 1 through 9 are generally bounded by Naval Air Station North Island to the west, Ocean Boulevard to the south, Glorietta Boulevard and Pomona Avenue to the east, and 1st Street to the north. Opportunity Site 10 is just south of the other opportunity sites on Naval Amphibious Base Coronado at Tulagi Road and, therefore, is under the jurisdiction of the U.S. Navy. The 10 opportunity sites are composed of 27 parcels of land and total approximately 199 acres. Currently, all 10 opportunity sites are at least partially developed and within approximately 0.5 mile of schools and commercial areas. This analysis focuses on the potential net increase in ambient noise levels attributable to the net increase of an additional 538 dwelling units compared to existing development in the City.

Noise Analysis Background
The California Department of Transportation defines “noise” as sound that is loud, unpleasant, unexpected, or undesired. Sound pressure levels are quantified using a logarithmic ratio of actual sound pressures to a reference pressure squared, called “bels.” A bel is typically divided into tenths, or decibels (dB). Sound pressure alone is not a reliable indicator of loudness because frequency (or pitch) also affects how receptors respond to sound. To account for the pitch of sounds and the corresponding sensitivity of human hearing to them, the raw sound pressure level is adjusted with a frequency-dependent A-weighting scale that is stated in units of decibels (dBA) (Caltrans 2013). 600 B Street, Suite 2000, San Diego, CA 92101 ◼ p: 619.236.1778 ◼ f: 866.785.0180 ◼ WeAreHarris.com City of Coronado Page 1212

A receptor’s response to a given noise may vary depending on the sound level, duration of exposure, character of the noise sources, time of day during which the noise is experienced, and activity affected by the noise. Activities most affected by noise include rest, relaxation, recreation, study, and communications. In consideration of these factors, different measures of noise exposure have been developed to quantify the extent of the effects from a variety of noise levels. The Community Noise Equivalent Level (CNEL) is the average equivalent A-weighted sound level over a 24-hour period. This measurement applies weights to noise levels during evening and nighttime hours to compensate for the increased disturbance response of people at those times. CNEL is the equivalent sound level for a 24-hour period with a +5 dBA weighting applied to sound occurring between 7:00 p.m. and 10:00 p.m. and a +10 dBA weighting applied to sound occurring between 10:00 p.m. and 7:00 a.m.

The dB level of a sound decreases (or attenuates) as the distance from the source of that sound increases. For a single point source, such as a piece of mechanical equipment, the sound level typically decreases by approximately 6 dBA for each doubling of distance from the source. Sound that originates from a linear (or “line”) source, such as vehicular traffic, attenuates by approximately 3 dBA per doubling of distance. Other contributing factors that affect sound reception include ground absorption, natural topography that provides a natural barrier, meteorological conditions, and the presence of human-made obstacles, such as buildings and sound barriers (Caltrans 2013).

Noise-sensitive land uses include noise receptors (receivers) where an excessive amount of noise interferes with normal activities. The Coronado Municipal Code lists hospitals, libraries, and selected park and beach areas for public refuge as potential noise-sensitive zones. Noise sources of note include landing aircraft at Naval Air Station North Island and traffic on State Routes 75 and 282, Ocean Boulevard, and Alameda and Ocean Boulevards (City of Coronado 1999).

Regulatory Setting
Local
Coronado General Plan
The Coronado General Plan Noise Element establishes noise and land use compatibility standards and outlines goals and policies to achieve these standards (City of Coronado 1999). New projects in the City are required to meet the noise exposure compatibility standards listed in Table 1, Coronado General Plan Noise Element Community Noise Sensitivity of Land Use (dBA CNEL), when evaluating the land use of proposed development projects. In residential, recreational, and hospital areas, the ambient noise level shall not exceed 50 dBA during the daytime (8:00 a.m. to 10:00 p.m.) and shall not exceed 45 dBA during the nighttime (10:00 p.m. to 8:00 p.m.).

Residential development shall not be allowed in “clearly unacceptable” or “normally unacceptable” areas.

Residential development may be allowed in “normally unacceptable” areas if precautions are taken during construction and sound barriers are built prior to construction. In commercial and industrial areas, ambient noise levels shall not exceed 60 dBA during the daytime and shall not exceed 50 dBA during the nighttime. Commercial (retail) development shall not be permitted in commercial wholesale and farming areas that can exceed 80 dBA.

Special construction precautions and sound barriers prior to construction are required if the CNEL exceeds 75 dBA.

In Table 1, land uses identified as “clearly acceptable” may be carried out with little to no interference from aircraft noise. In residential areas, indoor and outdoor noise environments are pleasant. Land uses that fall into the “normally acceptable” range noise environment generally require only common building construction to make indoor environments acceptable. The outdoor environment is reasonably pleasant for residential areas. For land uses where the exterior noise level falls within the “normally unacceptable” range, unusual and costly building constructions may be necessary to ensure enjoyable activities. In residential areas, barriers are required between the site and prominent noise sources to make the outdoor environmental tolerable. For land uses where the exterior noise levels fall within the “clearly unacceptable” range, new construction generally shall not be undertaken. In residential areas, the outdoor environment would be considered intolerable for residential use (City of Coronado 1999).

Significance Thresholds
Implementation of the project would result in a significant direct impact if it resulted in an increase in vehicle noise levels exceeding the normally acceptable noise standard for residences (65 dBA CNEL) or in a noticeable (more than 3 dBA) increase in noise levels of roadways exceeding 65 dBA CNEL without the project. The project would also result in a significant impact if it resulted in the development of new sensitive receptors in areas exposed to noise levels in excess of the compatibility standards listed in Table 1. A significant cumulative impact would occur related to vehicle noise if cumulative growth resulted in future noise levels exceeding noise compatibility standards in areas that do not exceed 65 dBA CNEL under existing conditions. The project would result in a cumulatively considerable contribution if the project’s contribution exceeded 3 dBA CNEL on cumulatively impacted segments.

Impact Analysis
The following analysis includes an analysis of increases in vehicle noise that may result from project implementation and the potential for new sensitive receptors to be exposed to incompatible noise levels.

Permanent Increase in Vehicle Noise
The potential for implementation of the project to permanently increase ambient noise levels as a result of increased traffic was assessed using standard noise modeling equations adapted from the Federal Highway Administration Noise Prediction Model (Attachment 1, FHWA Noise Prediction Model Results). The modeling calculations take into account the posted vehicle speed, median width, average daily trip volume, and estimated vehicle mix. Traffic volumes and roadway characteristics with buildout of the project were obtained from Linscott, Law & Greenspan, Engineers (LLG 2024). Noise levels were calculated at 50 feet from the centerline of each roadway segment. Generally, noise from heavily traveled roadways experience a decrease of approximately 3 dBA for every doubling of distance. The actual sound level at any receptor location depends on such factors as the source-to-receptor distance and the presence of intervening structures, barriers, vegetation, and topography; therefore, the result of the calculations is the worst-case scenario.

The 10 Transportation Analysis study area segments that would experience the greatest percent increase in vehicle trips compared to existing conditions as a result of project implementation are modeled to represent the potential changes in traffic noise conditions. Timing of new housing in the City is unknown, and buildout is assumed to occur through the year 2050, during which regional growth and development elsewhere in the City will occur. Therefore, consistent with the Transportation Analysis, the significance of project direct impacts on ambient noise levels is evaluated based on a comparison of future (2050) noise levels with and without project implementation, including also a worst-case near-term scenario, which assumes a full project buildout. Although the project would implement planned growth, growth under the HEU in the Transportation Analysis is considered separately from this regional growth to identify HEU-level community impacts (LLG 2024).

Table 3, Near-Term Traffic Noise Levels With and Without Project Implementation, provides the worst-case nearterm buildout noise levels with implementation of the project from the 10 Transportation Analysis study area segments. Table 4, Future (Year 2050) Traffic Noise Levels with and without Project Implementation, provides longterm increases in noise levels with project implementation, accounting for regional growth. Table 5, Cumulative Vehicle Noise Impacts, evaluates the cumulative impact of long-term project buildout and regional development compared to near-term conditions. As shown in Table 3 and Table 4, Future (Year 2050) Traffic Noise Levels with and without Project Implementation, implementation of the project would not result in a direct noise impact on any study area segment. Additionally, as shown in Table 5, Cumulative Vehicle Noise Impacts, regional growth and the project would not result in any cumulative noise impacts. Therefore, implementation of the project would not result in direct or cumulatively considerable impacts related to permanent increases in vehicle noise in the City.

No mitigation is required.

Notes: dBA = A-weighted decibel; CNEL = community noise equivalent level Noise Incompatibilities with New Sensitive Receptors
In addition to the potential to increase vehicle noise as a result of future development, implementation of the project would have the potential to result in the placement of new sensitive receptors in areas that would be exposed to vehicle noise levels in excess of the City’s noise and land use compatibility standards. As shown in Table 3 through Table 5, vehicle noise would generally be within the normally acceptable noise level range of up to 65 dBA CNEL at 50 feet from roadway centerlines under existing and future conditions. Therefore, conventional construction—such as wall, insulation, and window design consistent with current building codes—would generally be sufficient to reduce noise exposure to an acceptable level. However, noise levels higher than 65 dBA CNEL are calculated for portions of 3rd Street from Orange Avenue to B Avenue (65 dBA CNEL up to 75 feet from centerline), Orange Avenue from 3rd Street to 10th Street (65 dBA CNEL up to 120 feet from centerline), and Silver Strand Boulevard (65 dBA CNEL up to 140 feet from centerline). Opportunity Site 8 is located along Orange Avenue, between 7th Street and 8th Street, and new development may be within the 65 dBA CNEL contour for this roadway. However, any new development would continue to be required to demonstrate incorporation of adequate noise attenuation to achieve acceptable noise levels prior to project approval. Noise attenuation would 6 City of Coronado Page 1217
Attachment 9
continue to be required under the Coronado General Plan Noise Element and California Building Code interior noise standards. Opportunity sites other than Opportunity Site 8 are not along roadways calculated to exceed 65 dBA CNEL. Therefore, implementation of the project would not result in a significant impact related to exposure of new sensitive receptors to ambient noise levels in excess of the City’s noise and land use compatibility standards. This impact would be less than significant.

Mitigation Measures
No mitigation measures are required.

Summary
Implementation of the project would not result in a significant direct or cumulative permanent increase in vehicle noise level. New sensitive receptors accommodated by the HEU would have the potential to be exposed to noise levels in excess of normally compatible noise standards. However, compliance with Coronado General Plan Noise Element and California Building Code requirements would reduce impacts related to exposure to vehicle noise to a less than significant level without mitigation.

CORONADO HOUSING ELEMENT
Coronado, California
February 8, 2024

1.0 INTRODUCTION
The City of Coronado (hereafter referred to as “City”) is proposing the 6th Cycle 2021–2029 Housing Element Update (HEU or hereafter referred to as “Project”), which would update the Housing Element and amend the Coronado General Plan land use and zoning designations. The project area includes 10 opportunity sites, which are composed of 27 parcels of land and total approximately 198 acres throughout the City. As part of the Housing Element Update, an increase of 912 residential units could result. Linscott, Law and Greenspan, Engineers (LLG) has prepared this Transportation Analysis to outline the potential Vehicle Miles Traveled (VMT) and Level of Service (LOS) impacts of the traffic that the housing units will generate throughout the City.

2.0 PROJECT DESCRIPTION
As described in Section 1 Introduction, the City is proposing the 6th Cycle 2021–2029 Housing Element Update (HEU), which would update the Housing Element and amend the Coronado General Plan land use and zoning designations. The Housing Element provides policy framework to promote production of necessary housing while preserving the existing housing stock and preventing tenant displacement. The project area includes 10 opportunity sites, which are composed of 27 parcels of land and total approximately 198 acres throughout the City.

Figure 2-1 depicts the Vicinity Map.

2.1 Project Background and History
As a mandated element of the Coronado General Plan, the Housing Element must meet all requirements of existing state law. Goals, programs, policies, and quantified objectives in the Housing Element are consistent with state law and are implemented within a designated timeline to ensure that the City accomplishes the identified actions and maintains compliance with state law.

2.2 Regional Housing Needs Assessment
The SANDAG Board of Directors adopted the Final Regional Housing Needs Assessment Allocation (RHNA) Plan for the 6th Housing Element Cycle (April 15, 2021–April 15, 2029) on July 10, 2020.

The RHNA allocates housing needs in four income categories (very low, low, moderate, and above moderate) for each jurisdiction used in Housing Elements. Table 2-1, Coronado Regional Housing Needs Assessment Allocation 2021–2029, outlines the City’s RHNA allocation and indicates that the City’s RHNA allocation for the 6th Housing Element Cycle is 912 dwelling units.

2.3 Navy Housing
The U.S. Navy has received funding to construct a housing development for approximately 600 enlisted personnel on Naval Amphibious Base Coronado of which the City of Coronado can take credit for 374 housing units towards their RHNA. In total, 305 units would be lower income, with 69 LINSCOTT, LAW & GREENSPAN, engineers LLG Ref. 3-23-3827 Coronado Housing Element

attributable to the moderate-income level. This development is anticipated to occur within the 2021– 2029 6th Cycle Housing Element period. Table 2–2 summarizes the capacity of each site.

2.4 OPPORTUNITY SITES
The Draft HEU meets the assigned RHNA allocation plus the No Net Loss buffer through the following sites inventory:
• Entitled or Proposed Projects (Pipeline): In total, 146 pending or entitled housing units are proposed to be used toward the RHNA allocation. This is a mix of market rate projects that have recently been completed, or are currently under construction, approved for construction, or proposed for construction.
• Accessory Dwelling Units: The City expects to be able to credit a total of 195 accessory dwelling units (ADUs) toward its RHNA allocation.
• Carriage House Conversions: The City expects to be able to credit a total of 103 carriage house units toward the RHNA allocation.
• Opportunity Sites including Navy Housing: To achieve a reasonable capacity buffer, the City identified 10 additional sites, including the Navy Housing site, that could accommodate future housing. Note that the HCD requirements call for privately owned sites to be a minimum 0.5 acre in size, and most properties in the City do not meet that threshold. As shown in Table 2-2, Opportunity Sites Unit Count, there are 10 opportunity sites that can accommodate 827 housing units to meet the RHNA allocation.

The Draft HEU shows that there is capacity for at least 1,271 housing units in the City from the above listed sources to achieve the required RHNA allocation plus No Net Loss buffer.

The Sites Inventory was prepared to satisfy state requirements and is a planning estimate based on a number of factors. However, the Sites Inventory does not approve any project or guarantee what will be built on the sites. Actual housing development is implemented by the development community and will be largely dependent on market factors that are outside the City’s control. Housing developers, market trends, and availability of funding are among the constraints that will dictate if and when housing units will be constructed. The following are brief descriptions of the opportunity sites. Each opportunity site is assigned a number from 1 through 10. Table 2-2 summarizes the number of units by site.

2.4.1 Site 1: 919 C Avenue
Opportunity Site 1 is a 0.62-acre site currently zoned as Multifamily Residential (R-3) at 28 du/ac.

The site is currently owned by the Parish of Christ Church. The site is proposed to be rezoned at Multi Family Residential (R-4), or 40 du/ac equivalent. The realistic capacity analysis for the Multi-Family Residential (R-4) zone indicates a 75 percent actual density based on recently approved projects. This 75 percent assumption of the total density capacity projects that 19 units could be developed. The site’s strong access to amenities, municipal services, and schools makes it an excellent candidate for lower-income units.

and Palm Academy for Learning are within 0.5 mile of the site. Coronado Middle and Village Elementary Schools are just outside 0.5 mile but still within proximity.

2.4.2 Site 2: 517 Orange Avenue
Opportunity Site 2 is a 0.08-acre site currently zoned as Multifamily Residential (R-4). It is currently a duplex property that was recently purchased by the City with plans to convert it to affordable housing at the lower-income level. No zone change is proposed for the site; however, three lower-income units could replace two above moderate-income units, resulting in one net new unit. The City would follow all legal requirements for relocation and replacement housing for the two existing above moderateincome units and would follow all legal requirements under the California Surplus Land Act. In accordance with the Surplus Land Act, the City would advertise the property to affordable housing developers for potential redevelopment. The site also has strong access to amenities, municipal services, public transportation, and schools, which makes it another great candidate for lower-income units. These amenities include a Smart & Final Extra! On B Avenue (or the projected grocery development on Opportunity Site 5), the Orange Avenue Vons grocery store, and Spreckels Park, which are within 0.5 mile of the site. Coronado High, Coronado Middle, and Village Elementary Schools are also within 0.5 mile of the site.

2.4.3 Site 3: 1224 Tenth Street
Opportunity Site 3 is a 0.55-acre site currently zoned as Commercial © within the Orange Avenue Corridor Specific Plan (OACSP). The site is currently an office building. The site is proposed to be rezoned at Multi Family Residential (R-4), or 40 du/ac equivalent, with an allowance for mixed uses.

A capacity of 50 percent is assumed. The site has great access to amenities, municipal services, and schools. A Vons grocery store, along with Rotary and Star Parks, are within 0.5 mile of the site.

Coronado High School is also within 0.5 mile of the site. Coronado Village Elementary and Coronado Middle School are each just outside 0.5 mile but are convenient to future households at the site. A total of 11 units could be built at this site.

2.4.4 Site 4: 1001 C Avenue
Opportunity Site 4 is a 0.57-acre site currently zoned as Commercial (C) within the OACSP. This site is a retail property adjacent to Opportunity Site 3 at the corner of Tenth Street and C Avenue with strong mixed-use development potential. The site is proposed to be rezoned at Multi Family Residential (R-4), or 40 du/ac equivalent, with an allowance for mixed uses. A capacity of 50 percent is assumed. The site also has great access to amenities, municipal services, and schools. A Vons grocery store, along with Rotary and Star Parks, are within 0.5 mile. Coronado High School is also within 0.5 mile of the site. The Coronado Middle and Village Elementary Schools are each just outside

0.5 mile but are convenient for future households on the site. A total of 11 units could be built at this site.

2.4.5 Site 5: 150 B Avenue
Opportunity Site 5 is a 2.89-acre site currently zoned as Commercial (C) within the OACSP.

Opportunity Site 5 is a group of properties with several retail and commercial uses, including Smart & Final Extra! Taco Bell, KFC, Navy Federal Credit Union, and a one-story medical office building.

The property owners have expressed interest in developing housing units on the site. The site is proposed to be rezoned at Multi Family Residential (R-4), or 40 du/ac equivalent, with an allowance for mixed uses. A capacity of 58 units is assumed. Local residents would like grocery use to continue on the site, and City staff would work with the owner/developer to incorporate a grocery component.

The site provides excellent amenities with Boney’s Bayside Market, Centennial Park, and Harborview Park within 0.5 mile. A total of 58 units could be built at this site.

2.4.6 Site 6: 149 A Avenue
Opportunity Site 6 is a 1.28-acre site currently zoned as Residential – Planned Community Development (R-PCD). It is currently a parking lot directly adjacent to Opportunity Site 7 and has excellent development potential. Opportunity Site 6 is proposed to be rezoned to allow for 60 du/ac equivalent. For unit calculation, however, 40 du/ac was assumed because 549 units are adjacent to Opportunity Site 7. At 40 du/ac with a realistic capacity of 75 percent per analysis in this chapter, the site can realistically accommodate 38 units. The site has great access to amenities with a Smart & Final Extra! (or an anticipated grocery use on Opportunity Site 5), Boney’s Bayside Market, and Centennial and Tidelands Parks within 0.5 mile. The site also has close access to the San Diego– Coronado Bridge along State Route 75 (SR-75).

2.4.7 Site 7: 517 1515 Second Street
Opportunity Site 7 is a 12.66-acre site currently zoned as Residential – Planned Community Development (R-PCD). It is a large, multifamily residential parcel that is home to the three-story, 549- unit Bayside at Coronado Apartments. The 12.66-acre site contains 5.42 acres of underutilized space consisting of parking spaces, tennis courts, and a swimming pool/common area. The proposed zoning for the site is zoning equivalent to 60 du/ac. The City projects that an additional 167 units could be developed on the site for mixed incomes, including 12 lower-income units and 55 moderate-income units. The site is within 0.5 mile of Smart & Final Extra!, Boney’s Bayside Market, and Centennial and Tidelands Parks. The site also has close access to the San Diego–Coronado Bridge along SR-75.

2.4.8 Site 8: 700 Orange Avenue
Opportunity Site 8 is a 1.58-acre site currently zoned as Civic Use (CU) and Multi Family Residential (R-4). The site currently houses both the Coronado Police Department and an underutilized AT&T switching facility owned by Pacific Bell Telephone Company. The site is proposed to be rezoned at Multi Family Residential (R-4), or 40 du/ac equivalent with Civic Use (CU). The City projects that 47 lower-income units could be accommodated on the site. Housing for very low-income veterans is a potential affordable housing project. Because the City owns the majority of the site, a strong projection of 100 percent lower-income units, potentially for veterans, on the site is proposed. The site is also an excellent candidate for lower-income units with access to amenities within 0.5 mile, including a Vons grocery store; Spreckels Park; and Coronado High, Coronado Middle, and Village Elementary Schools.

2.4.9 Site 9: 201 Sixth Street
Opportunity Site 9 is a 3.36-acre site currently zoned as Civic Use (CU). The site is currently owned by the Coronado Unified School District and is a former school that closed due to lower enrollment.

The property currently houses a childcare and pre-kindergarten center. The site is proposed to be rezoned at Multi Family Residential (R-4), or 40 du/ac equivalent. The realistic capacity analysis for the Multi-Family Residential (R-4) zone indicates a 75 percent actual density based on recently approved projects. It is projected that there would be a total of 101 units with 67 lower-income units and 34 moderate-income units. The site’s strong access to amenities, municipal services, and schools makes it an excellent candidate for lower-income units. It is located within one-half mile of the North Island Commissary (which is accessible to military personnel and their families only), Glen Curtiss and Pendleton Parks, as well as Coronado High, Coronado Middle, and Coronado Village Elementary schools. The site is also 1 mile from the Vons grocery store on Orange Avenue.

2.4.10 Site 10: 3632 Tulagi Road (Navy Housing)
Opportunity Site 10 is a 175.21-acre site currently zoned as Military Zone (MZ). The site is owned and operated by the U.S. Navy. It is important to note that the U.S. Navy, like other state and federal agencies, does not require development approvals or permits (from either the City or California Coastal Commission) to develop. Environmental review under CEQA is also not required. The U.S.

Navy obtained federal funding to build units to house approximately 600 sailors. Opportunity Site 10 is close to the Vons grocery store and the City’s schools, with access to a nearby bus stop that is a 10– LINSCOTT, LAW & GREENSPAN, engineers LLG Ref. 3-23-3827 Coronado Housing Element

15-minute walk from the site. The U.S. Navy base also has its own amenities, including various restaurants, Turner Field and CISM Field, a movie theater, and a large swimming pool. Glorietta Bay Park and Promenade are also near the site. This housing equates to a credit of 374 units.

Therefore, the 10 opportunity sites described above account for a total of 827 units. However, to be conservative, the traffic analysis assumed that an additional 85 units would be provided throughout the City, accounting for a total of 912 new units in the City. The location of these 85 units were “assumed” in four locations for the purpose of this analysis, since it is not known at this time. With the credit of 374 units for the proposed Navy housing, this study analyzes the impact of 538 additional units (912-374 units).

3.0 VMT ANALYSIS

3.1 VMT Background
Vehicle miles traveled (VMT) is a measurement of miles traveled by vehicles within a specified region and for a specified period. VMT measures the efficiency of the transportation network. VMTs are calculated based on individual vehicle trips generated and their associated trip lengths. VMT accounts for two-way (round-trip) travel and is often estimated for a typical weekday to measure transportation impacts.

On September 27, 2013, Governor Jerry Brown signed Senate Bill 743 (SB 743). SB 743 created a process to change the way analysis of transportation impacts under the California Environmental Quality Act (CEQA) is conducted. The Governor’s Office of Planning and Research (OPR) was tasked to amend the CEQA Guidelines to provide an alternative to the traditional metric of automobile delay which would promote three statutory goals: 1) the reduction of greenhouse gas (GHG) emissions; 2) the development of multimodal transportation networks; and 3) a diversity of land uses. OPR concluded that the use of Vehicle Miles Traveled (VMT), with thresholds linked to GHG reduction targets, would adequately analyze a project’s transportation impacts while supporting all three statutory goals.

OPR released a preliminary evaluation of alternative methods for transportation analysis in December 2013, and by August 2014, released a preliminary discussion draft of potential updates to the CEQA Guidelines, which specified VMT as the selected metric for analysis. In 2016, OPR released a draft of the proposed revisions to the CEQA Guidelines. At the same time, OPR released a new Technical Advisory for Evaluating Transportation Impacts In CEQA, which provides technical recommendations regarding the implementation of VMT analysis state-wide in a document external to the CEQA statute.

After extensive stakeholder outreach, OPR transmitted the final proposed revisions to the CEQA Guidelines and the current draft of the Technical Advisory to the California Natural Resources Agency (the body responsible for certifying, adopting, and amending the CEQA Guidelines) in November 2017. Beginning in January 2018, the California Natural Resources Agency initiated the formal rulemaking process to adopt the proposed revisions, including the new Section 15064.3 which specifies VMT as the metric for transportation analysis. On December 28, 2018, the California Office of Administrative Law filed the revised CEQA Guidelines with the Secretary of the State on behalf of the Natural Resources Agency, thereby formally implementing vehicle miles traveled as the metric for transportation analysis under CEQA. Pursuant to the adopted Section 15064.3, a lead agency may elect to implement the new criteria for analyzing transportation impacts immediately. Beginning on July 1, 2020, the criteria must be applied state-wide.

3.2 Local / Regional Agency Transition to SB743
The City of Coronado does not have published VMT methodologies and thresholds and therefore the OPR guidelines were utilized.

3.3 Project VMT Analysis
The Project generated Vehicle Miles Traveled (VMT) were manually calculated as shown in Table 3-1. VMT related to the Project’s residential DUs was calculated based on the Project’s trip generation (summarized in Section 7), the Regional Average Household size of 1.74 residents per DU sourced from the SANDAG 2016 Series ABM2+/2021 RP Mode Choice Model (included in Appendix A), and an average residential trip length of 9.0 miles sourced from the Coronado-specific SANDAG 2016 Series ABM2+/2021 RP Mode Choice Model. Based on these assumptions, the Project’s residential component, if all opportunity sites are developed to maximum densities, is expected to result in 936 additional residents and 38,736 additional VMT.

The Project’s military housing component will allow approximately 600-sailors, who are currently commuting to base from throughout the San Diego region to work on base, thereby resulting in a reduction of two (2) commute trips per military housing bed, and an associated reduction in VMT.

The reduction in VMT associated with the Project’s military housing component was calculated based on the proposed number of beds, the assumption that one bed equals one resident, and an Employee Round-Trip Commuter Tour Length of 26.2-miles sourced from the Coronado-specific SANDAG 2016 Series ABM2+/2021 RP Mode Choice Model. Based on these assumptions, the Project’s military housing component is expected to result in approximately 600 additional residents and a reduction of 15,720 VMT.

The 2016 Regional average VMT per resident is 18.9 miles. The threshold within which the project will not have an impact is 85% of the average VMT per resident or 16.1 miles (85% of 18.9 miles).

Based on the above, the Project is calculated to generate 1,536 additional residents including the 600 sailors (936+600) with a net-increase of 23,016 VMT, which equates to a Project-specific VMT/Resident of 14.98 miles which is within the threshold of 16.1 miles.

4.3 Methodology
Peak hour intersection and segment analyses were performed in each of the above scenarios to determine the potential effects of the Project on the roadway network. There are various methodologies used to analyze signalized intersections, unsignalized intersections and street segments.

The measure of effectiveness for intersection and segment operations is level of service (LOS) which denotes the operating conditions which occur at a given intersection or on a given roadway segment under various traffic volume loads. It is a qualitative measure used to describe a quantitative analysis taking into account factors such as roadway geometries, signal phasing, speed, travel delay, freedom to maneuver, and safety. LOS provides an index to the operational qualities of a roadway segment or an intersection. LOS designations range from A to F, with LOS A representing the best operating conditions and LOS F representing the worst. LOS designation is reported differently for signalized and unsignalized intersections, as well as for roadway segments.

Signalized Intersections
In the Highway Capacity Manual (HCM 6th Edition), LOS for signalized intersections is defined in terms of delay. The LOS analysis provides results in seconds of delay expressed in terms of letters A through F. Delay is a measure of driver discomfort, frustration, fuel consumption, and lost travel time.

Table 4–1 summarizes the signalized intersection LOS descriptions.

Table 4–2 depicts the criteria, which are based on the average control delay for any particular minor movement (unsignalized intersections) and overall intersection (signalized intersections). For signalized intersections, LOS criteria are stated in terms of the average control delay per vehicle for a 15-minute analysis period. Control delays include initial deceleration delay, queue move-up time, stopped delay, and final acceleration delay.

Signal Timing plans were obtained from the City of Coronado and Caltrans for the signalized intersections in the Project study area and used in the intersection analysis. Copies of the City of Coronado signal timing plans are included in Appendix B.

4.4 Improvement Triggers
Following are the triggers when an improvement is required at an intersection:
• The project causes the average intersection delay to be LOS E or F during the peak hour. • The project adds 2.0 or more seconds of delay to an intersection that is currently operating at LOS E or F during the peak hour.

INTERSECTION LEVEL OF SERVICE DESCRIPTIONS
LOS Description
A Occurs when progression is extremely favorable, and most vehicles arrive during the green phase.

Most vehicles do not stop at all. Short cycle lengths may also contribute to low delay.

B
C
Generally, occurs with good progression and/or short cycle lengths. More vehicles stop than for LOS A, causing higher levels of average delay.

Generally, results when there is fair progression and/or longer cycle lengths. Individual cycle failures may begin to appear at this level. The number of vehicles stopping is significant at this level, although many still pass through the intersection without stopping.

D
E
F
Generally, results in noticeable congestion. Longer delays may result from some combination of unfavorable progression, long cycle lengths, or high volume-to-capacity ratios. Many vehicles stop, and the proportion of vehicles not stopping declines. Individual cycle failures are noticeable.

Considered to be the limit of acceptable delay. These high delay values generally indicate poor progression, long cycle lengths, and high volume-to-capacity ratios. Individual cycle failures are frequent occurrences.

Considered to be unacceptable to most drivers. This condition often occurs with over saturation i.e. when arrival flow rates exceed the capacity of the intersection. It may also occur at high volumeto-capacity ratios below 1.00 with many individual cycle failures. Poor progression and long cycle lengths may also be major contributing causes to such delay levels TABLE 4–2

7.0 TRIP GENERATION/DISTRIBUTION/ASSIGNMENT
Trip generation rates for Condominiums land use from the (Not So) Brief Guide of Vehicular Traffic Generation Rates for the San Diego Region, April 2002 SANDAG were used for the proposed Project.

7.1 Project Trip Generation

7.1.1 Project Traffic
As described in Section 2 Project Description, 10 opportunity sites that have been identified account for a total of 827 units. However, to be conservative, the traffic analysis assumed that the additional 85 units would be provided throughout the City, accounting for a total of 912 new units in the City.

With the credit of 374 Navy housing units, this study analyzes the impact of 538 additional units (912- 374 units). As explained above, trip generation was calculated based on 538 units. During the peak hours, traffic generated by the naval housing will not leave the base as they work on base. Therefore, it is assumed that the Naval housing (374 units) does not add traffic to the City streets during the peak hours.

The trip generation is summarized in Table 7-1. As summarized in Table 7-1, the Project is estimated to generate a total of approximately 4,304 average daily trips with 344 AM peak hour trips (69 inbound and 275 outbound) and 430 PM peak hour trips (301 inbound and 129 outbound). The total project traffic is the Project traffic generated by 538 units, less the traffic generated by the 600 sailors.

7.1.2 New Naval Housing
As mentioned previously, the Navy is building housing for approximately 600 sailors on the Naval Amphibious Base at Tulagi Road, off of Silver Strand Boulevard. Currently, these sailors are commuting to Coronado, to the Naval Amphibious Base. With the availability of the new housing, they will no longer need to commute from San Diego or elsewhere. Therefore, traffic generated by these sailors will no longer be on Coronado Streets and this traffic was deducted from the existing traffic volumes.

7.2 Project Trip Distribution
Individual trip distribution was developed for each of the 10 Opportunity sites and 4 assumed sites (as explained in Section 2.4.10), for a total of 14 sites. In general, it was assumed that 60% of the Project traffic is oriented towards San Diego across the Coronado bridge, 10% to the north towards North Island, between 10 to 15% towards the south along Silver Strand Boulevard and the remaining is assumed to be local traffic.

Project trip distribution for the 14 individual (opportunity and assumed) sites is included in Appendix F.

7.3 Project Trip Assignment
The Project traffic was assigned to the Project study area intersections based on the trip distribution explained above. The trip assigned for each individual site was added to obtain the total Project trips LINSCOTT, LAW & GREENSPAN, engineers LLG Ref. 3-23-3827 Coronado Housing Element

Attachment 9
at each study area intersection. Project trip assignment for the individual (opportunity and assumed) sites is included in Appendix F.

The traffic related to the 600 sailors is assumed to have been oriented to the Naval Amphibious Base and is so assigned. The traffic generated by the 600 sailors was deducted from the traffic generated by the 538 Project units and assigned to the study area intersections. Any negative volumes at some intersections are due to the peak hour traffic related to the 600 sailors being reversed from the Street system.

Figure 7–1 depicts the Typical Project Traffic Distribution and Figure 7–2 depicts the total Project Traffic Assignment.

8.0 CUMULATIVE PROJECTS AND TRAFFIC VOLUME FORECAST

8.1 Mid-Term (Year 2030) Traffic Volumes

8.1.1 Ambient Growth
An ambient growth was added to the existing traffic to account for potential growth in traffic between 2023 and the near-term study year of 2030. A review of historical traffic volumes on Orange Avenue (SR 75) was conducted. It was determined that traffic has been relatively flat between the years of 2016 and 2018. To be conservative, it was decided to increase existing traffic by a growth factor of

0.5% per year.

8.1.2 Cumulative Projects
In consultation with City of Coronado staff, 5 near-term cumulative Projects were identified.

Table 8-1 summarizes the trip generation for the 5 near-term cumulative projects. The following provides a brief description of these cumulative projects.

1. 970 C Avenue proposes to demolish the 5,860 sf of commercial office to construct 9,908 sf of religious / assembly use. The project is expected to generate 28 less ADT.

2. 543 – 555 Orange Avenue proposed to construct 10 multi-family residential units. The project is expected to generate 80 ADT.

3. 737 – 753 Orange Avenue proposes to demolish 7 multi-family residential units to construct 12 new multi-family residential units. The project is expected to generate 40 ADT.

4. 1315 Orange Avenue proposes to construct 4,372 sf of restaurant. The project is expected to generate 700 ADT.

5. 1417 Orange Avenue proposes to demolish 15 hotel rooms and construct 39 new hotel rooms and a 2,000 sf of restaurant. The project is expected to generate 560 ADT.

As seen in Table 8-1, the cumulative projects are estimated to generate a total of approximately 1,380 ADT with 106 AM peak hour trips (52 inbound and 54 outbound) and 113 PM peak hour trips with (71 inbound and 42 outbound). The trips generated by these cumulative projects were assigned to the Project study area intersections.

Figure 8–1 is the Cumulative Projects Location Map and Figure 8–2 depicts the Cumulative Projects Traffic Volumes.

8.1.3 Methodology
Following is the methodology used to develop the Mid-Term (Year 2030) without Project traffic volumes:
• Add an annual growth of 0.5% for 7 years (Year 2023 through Year 2030) to the existing traffic.
• Add the traffic generated by the Cumulative Projects (Figure 8-2).

9.0 MID-TERM YEAR 2030 ANALYSIS

9.1 Mid-Term Year 2030 Without Project Intersection Analysis Table 9-1 summarizes the Mid-Term Year 2030 without Project peak hour intersection analysis results. As shown in Table 9-1, all signalized and unsignalized intersections are expected to continue to operate at LOS D or better except the following:
• Orange Avenue / Third Street – LOS E during the PM peak hour • Orange Avenue / Fourth Street – LOS E during the PM peak hour • Orange Avenue / Adella Avenue / Rh Dana Place – LOS E during the AM peak hour Appendix G includes the Mid-Term Year 2030 without Project peak hour intersection analysis worksheets.

9.2 Mid-Term Year 2030 With Project Intersection Analysis Table 9-1 summarizes the Mid-Term Year 2030 with Project peak hour intersection operations. The “Project” volumes include traffic generated by new housing units and volumes deducted from the street system since approximately 600 sailors will no longer need to commute into Coronado.

Therefore, some intersections will have a decrease in overall delay.

As shown in Table 9-1, with the addition of Project traffic, all signalized and unsignalized intersections are expected to continue to operate at LOS D or better except the following:
• Orange Avenue / Third Street – LOS E during the PM peak hour • Orange Avenue / Fourth Street – LOS E during the PM peak hour • Orange Avenue / Adella Avenue / Rh Dana Place – LOS E during the AM peak hour No improvements are required at the above three intersections since the Project adds less than 2 seconds of delay.

Appendix H includes the Mid-Term Year 2030 with Project peak hour intersection analysis worksheets.

10.0 LONG-TERM YEAR 2050 ANALYSIS

10.1 Long-Term Year Traffic Volumes
Year 2050 segment volumes were obtained from the SANDAG ABM2 2021RP model. These were compared to the Year 2022 segment volumes obtained from the City of Coronado. In instances where the Year 2050 volumes were less than the Year 2022 volumes, the Year 2050 volumes were increased by applying a factor of 10% to the Year 2022 volumes. Year 2050 peak hour turning movement volumes were estimated using a template in EXCEL developed by LLG to determine peak hour traffic at an intersection from future ADT volumes using the relationship between existing peak hour turn movements and the existing ADT volumes. This same relationship can be assumed to generally continue in the future. For example, if the segment ADT on the roadway is forecast to double by the Year 2050, it is reasonable to assume that the peak hour intersection turning movement volumes will generally double.

Figure 10–1 depicts the Long-Term Year 2050 Without Project Traffic Volumes and Figure 10–2 depicts the Long-Term Year 2050 + Project Traffic Volumes.

10.2 Long-Term Year 2050 Without Project Intersection Analysis Table 10-1 summarizes the Long-Term Year 2050 without Project peak hour intersection analysis results. As shown in Table 10-1, all signalized and unsignalized intersections are expected to continue to operate at LOS D or better with the except at the following intersections:
• Orange Avenue / Third Street – LOS E during the PM peak hour • Orange Avenue / Fourth Street – LOS E during the PM peak hour • Orange Avenue / Adella Avenue / Rh Dana Place – LOS E during the AM peak hour Appendix I includes the Long-Term Year 2050 without Project peak hour intersection analysis worksheets.

10.3 Long-Term Year 2050 With Project Intersection Analysis Table 10-1 summarizes the Long-Term Year 2050 with Project peak hour intersection operations. As explained previously, the “Project” volumes include traffic generated by new housing units and volumes deducted from the street system since approximately 600 sailors will no longer need to commute into Coronado. Therefore, some intersections will have a decrease in overall delay.

As shown in Table 10-1, with the addition of Project traffic, all signalized and unsignalized intersections are expected to continue to operate at LOS D or better except at the following intersections:
• Orange Avenue / Third Street – LOS E during the PM peak hour • Orange Avenue / Fourth Street – LOS E during the PM peak hour • Orange Avenue / Adella Avenue / Rh Dana Place – LOS E during the AM peak hour LINSCOTT, LAW & GREENSPAN, engineers LLG Ref. 3-23-3827 Coronado Housing Element

The Project’s military housing component will allow approximately 600-sailors, who are currently commuting to base from throughout the San Diego region, to both live and work on base, thereby resulting in a reduction of two (2) commute trips per military housing bed, and an associated reduction in VMT. The Project’s military housing component is expected to result in approximately 600 additional residents and a reduction of 15,720 VMT.

The 2016 Regional average VMT per resident is 18.9 miles. The threshold within which the project will not have an impact is 85% of the average VMT per resident or 16.1 miles (85% of 18.9 miles).

Based on the above, the Project is calculated to generate 1,536 additional residents with a net-increase of 23,016 VMT, which equates to a Project-specific VMT/Resident of 14.98 miles which is within the threshold of 16.1 miles.

11.2 LOS Analysis
The additional housing will add traffic to the street system. In addition, traffic will be reduced since approximately 600 sailors will no longer need to commute to Coronado since they will be housed on the Naval Amphibious Base. The LOS analysis shows that no intersection improvements are necessary.
