ATTACHMENT A – PUENTE DEL MONTE WATER USE DEMAND
FACTORS
In earlier drafts of this WSA, the Puente Del Monte (PDM) Specific Plan1community was considered part of the Proposed Project, and detailed analysis of its expected water demands was performed by Zanjero. Ultimately, the Proposed Project description was revised to include only the Vista Lucia Community, with the Puente Del Monte Community analyzed as one of the Other Planned Uses to be served by the City of Gonzales. The detailed analysis of Puente Del Monte’s future water demands is included in this WSA as Attachment A.
The Puente Del Monte community will be developed on 585 acres located partly within the City of Gonzales and partly within the City’s Sphere of Influence in Monterey County. The developable areas will contain low to high density housing, open space, commercial, light industrial and school uses. An agriculture buffer bounds a majority of the Specific Plan area providing transition from farmlands to the built environment. The remainder of this attachment described the methodology used to calculate the indoor and outdoor residential and nonresidential water demand associated with the PDMSP community.
A.1 LAND USE AND CONSTRUCTION PHASING
The PDM community includes several residential and non-residential land-use classifications including market rate housing, mixed use commercial and residential elements, public facilities such as schools, parks (including trails and plazas), and open space (including storm water retention and agricultural buffers). The construction of the PDM community will be conducted in phases, as depicted in Table A-1. The land use of the PDM community at full buildout is represented as the condition in 2050.

A.2 RESIDENTIAL WATER USE DEMAND FACTORS
The PDMSP community anticipates five general residential land use designations. The size of the lot generally has the greatest impact on the annual per-lot demand for water as the irrigation needs for landscaping generally increase with larger landscaped areas. However, as discussed previously, the PDMSP includes defined plant material selection and design that significantly reduces the outdoor component of the forecast residential water demands compared to more conventional landscape designs, thus limiting, but not eliminating, this traditional lot-size effect.
In contrast, indoor water demands remain relatively consistent regardless of lot size, but do vary slightly based on the number of people per dwelling unit. Distinct demand factors are provided for the following residential uses:
Indoor Residential Use – this category identifies the generally anticipated water use for the varied residential housing types.
Outdoor Residential Use – this category addresses the landscape water demands for the various planned lot sizes.
For purposes of this WSA, residential unit water demand factors are described as “the acre-feet of water use annually per dwelling unit” – or acre-feet/dwelling unit (“af/du”). Both indoor and outdoor residential water demands will be met with potable water supplied by the City.
A.2.1 Indoor Residential Water Use Factors
The PDM residential elements would be built in accordance with all applicable building codes including the Cal Green Code discussed previously, as it may be further modified prior to Proposed Project implementation.
The indoor demands are estimated using an assumed value of 55 gallons-per person per day, multiplied by the assumed occupancy rates for conventional and high-density residential classifications.
For purposes of this WSA, conventional housing assumes an average occupancy rate of 4.4 people per house, while the high-density and mixed-use classifications assume 3.4 persons per house.2 The assumed per-person rate of 55 gallons per day is derived from California Water Code Section 10608.20(b)(2)(A), which states a value of 55 gallons per capita (i.e., per person) per day (“gpcd”) be used for estimating indoor residential use targets. When multiplied, the perperson use results in a per-dwelling unit demand of 0.27 acre-feet per year for conventional and mixed-used housing and 0.21 for high-density housing.
The 55 gpcd indoor use value has been confirmed through analyses of residential water meter data and is reflective of new suburban single-family dwelling units and older homes retrofitted with new water efficient fixtures and appliances.3
A.2.2 Outdoor Residential Water Use Factors
Outdoor water use is primarily a factor of lot size and the type and extent of landscaped area.
The PDM community includes up to 2,623 residential lots with five average lot sizes for the single-family classifications: 9,163 sf for LDR; 5,483 sf for MDR; 3,769 sf for MHDR; and 1,389 for HDR.4 Outdoor demands for the multi-family classification are calculated using net acreage values, which accounts for a street allowance as detailed below.
Outdoor demands for PDM are calculated based on a number of factors including the regulations and calculation methodologies contained in MWELO. The MWELO provides for determining the Maximum Applied Water Allowance (“MAWA”) where the maximum is determined as 55 percent of the reference evapotranspiration for the area, resulting in the following equation:5 2 City of Gonzles 2015 Housing Element indicates an average occupancy of 4.4 people per household for conventional housing (low – medium-high densities). 3.4 persons per household is assumed for high density and mixed-use housing.
3 With the increasingly stringent requirements of building codes as well as water and energy efficiency codes, it is likely that the actual indoor demand of the Proposed Project may be below the stated 0.23 af/yr. Recently, the Governor issued Executive Order B-37-16 that, among other orders, directed state agencies to develop new urban water use targets including a standard for indoor residential per-capita water use. These new targets are to “build upon the existing state law” that requires a 20% reduction in urban water use by 2020 – which already includes the suggested 55 gallons-per-person per day planning guidance. 4 Certain lots may be slightly larger or smaller, depending on the grading and final layout of the Proposed Project.
However, those variations will be nominal and will not materially affect the Proposed Project’s total demand. 5 This formula reflects the latest revision to the MAWA that became mandatory as of December 1, 2015.
MAWA = (ETo) (0.62) (0.55 x LA), where ETo is the reference evapotranspiration in inches per year, and LA is the landscape area in square feet. 0.62 is a conversion factor to gallons. The resulting value is in “gallons per year”
A primary factor in this calculation is evapotranspiration (“ET”). The methodology directs the use of ET from a reference crop, such as maintained grass – a value referred to as ETo. For PDM, the average ETo is 52.50 inches per year (or over 4.4 feet per year).6 Besides the ETo value, the primary factor driving outdoor water use on a per-lot basis is the square footage of landscape area. In addition to MWELO, the PDMSP relies on landscaping restrictions that exceed the MWELO maximums. Specifically, the PDMSP restricts turf to 25 percent of the landscaped area, and restricts plant choices to a majority of low and very-low water use species. More information about these restrictions is discussed in Section 2.1.1 of the main WSA document.
The calculations for water use are based on specific restrictions and the water efficient character as presented in the PDMSP. This WSA utilizes individual calculations for each parcel type based on typical landscape areas, plant types, and average plant water use factors defined in the PDMSP. The following assumptions form the basis of the residential landscape unit demand factors:
Plant Factors (PF) – based upon the plant palette of the PDMSP, the following factors are assumed:
o Turf = 0.6 (assumes use of certain Fescues, Bermuda Grass, and some other turf varieties with relatively low irrigation requirements. Some grass varieties, such as St Augustine, Zoysia, and Buffalo grass, may have factors less than 0.6.)
o Shrubs and Trees = 0.3
Because much of the landscape area will be trees and shrubs, the landscape area is reduced by 3 percent to reflect the “open/non-irrigated” space between plants. This area does not receive irrigation when using drip irrigation systems, which will be used for irrigating the trees and shrubs. This small deduction is reflected in the demand calculations for each residential lot category.
Using the plant factors and the MAWA equation, demand factors for each residential lot category are presented here:
6 ETo is consistent with California Irrigation Management Information System data available for the region. Low Density – The proposed 596 single-family dwellings will be built on lots with an average gross size of 10,181 sf, minus a 10 percent street allowance. For purposes of this WSA, an average of 6,163 sf of the lot is assumed to be landscaped7. Based on the MAWA equation, the resulting outdoor demand factor is forecast to be 0.23 acre-feet per dwelling unit.
Medium Density – The proposed 619 attached and detached single-family dwelling units in this classification will be constructed on lots with an average gross size of 5,960 sf minus an 8 percent street allowance. Other configurations within this classification, as described in the PDMSP, may include conventional small lot homes, alley, duplex, triplex, or townhomes. For purposes of this WSA, an average of 3,183 sf of the lot is assumed to be landscaped,8. The resulting outdoor demand factor is forecast to be 0.12 acre-feet per dwelling unit.
Medium-High Density – The proposed 794 multifamily and single-family attached dwelling units in this classification will be constructed on lots with an average gross size of 4,010 sf minus a 6 percent street allowance. Other configurations within this classification, as described in the PDMSP, may include duplexes, triplexes, townhomes, or flats. For purposes of this WSA, an average of 1,819 sf of the lot is assumed to be landscaped,9. The resulting outdoor demand factor is forecast to be 0.07 acre-feet per dwelling unit.
High Density – The proposed 569 units will include a variety of attached and multifamily dwellings on lots with an average gross size of 1,462 sf minus a 5 percent street allowance. Buildings can be configured as townhomes or flats. This dwelling unit type is typically associated with community controlled outdoor spaces so the average outdoor demands are quite low per unit. For purposes of this WSA, an average of 139 sf of the lot is assumed to be landscaped10. The resulting outdoor demand factor is forecast to be
0.01 acre-feet per dwelling unit.
7 Assumes net lot is 9,163 sf with 2,500 sf building footprint with 500 sf hardscape including driveway and patio. 8 Assumes net lot of 5,483 sf with 1,800 sf building footprint with 500 sf hardscape including driveway and patio. 9 Assumes net lot of 3,769 sf with 1,700 sf building footprint with 250 sf hardscape including driveway and patio. 10 Assumes net lot of 1,389 sf with 1,000 sf building footprint with 250 sf hardscape including driveway and patio. Mixed Use Residential. – The proposed Mixed-Use Area is primarily residential in character, with some homes also containing neighborhood commercial uses, as discussed below in section A.2.1. The entire Mixed-Use Area will be designed with the same specifications as the Medium Density residential area described above, including outdoor landscaping. It is forecast that the Mixed-Use area will have an outdoor demand factor of
0.12 acre-feet per dwelling unit for its 45 dwelling units, using the same calculation methodology as was used to calculate the Medium-Density outdoor residential demands.
A.2.3 Summary of Residential Water Use Demand Factors

A.3 NON-RESIDENTIAL WATER USE DEMAND FACTORS
The PDM community has several non-residential features ranging from a mixed-use neighborhood center, two schools, landscaped promenades, community gardens, and storm detention facilities. Many of these proposed land-uses are unique, requiring specific demand forecasts for each component.
For purposes of this WSA, the demand for non-residential classifications is described as either “the acre-feet of water use annually per acre of land,” acre-feet/acre (af/ac), or as a single demand projection for a demand category such as the indoor uses for the elementary schools, acre-feet/unit (af/unit). These values reflect indoor or outdoor water needs expected for typical non-residential use for each of the following classifications:
Mixed-Use Overlay Indoor
Elementary School Indoor
Light Industrial Indoor
Highway Commercial Indoor
Non-residential Outdoor
o Parks and Open Space
o Agricultural Buffer
o Elementary School
o Streetscape Landscaping
Other miscellaneous uses, including temporary irrigation to establish open space landscaping, and temporary construction water.
The method and basis for determining the unit water demand factor for each of these classifications is detailed in the following subsections.
A.3.1 Mixed-Use Overlay Commercial Indoor
The proposed Mixed-use area is anticipated to include up to 10,000 square feet (sf.) of commercial space spread across approximately 6 acres. The Mixed-Use area is expected to be primarily residential, but will allow for live/work arrangements within homes, such as salons, tax accountants, florists, and real estate agents, etc. These commercial activities will primarily include service, professional, and office uses, with some retail also possible. Commercial activities will occupy approximately 0.23 acres of the 6-acre zone. Based upon meter studies conducted on existing neighborhood commercial facilities elsewhere in California, coupled with the on-going commitment toward more efficient water use, the indoor unit demand factor for this classification is estimated at 1 acre-foot/acre for the purposes of this WSA. 11 The majority of the
Mixed-Use area’s land and water use will be residential, as discussed above in section A.2.
A.3.2 Elementary School Indoor
The PDMSP community includes two 10-acre elementary schools, totaling 20 acres. Based upon meter studies for existing elementary schools, total school use – indoor and outdoor – ranges from 20 to 30 gallons per day per student. Depending on the schools’ landscape design and operation, 60 to 70 percent of this demand is used to meet outdoor needs.12 Therefore, for purposes of this WSA, indoor demands are based upon an assumed use of 10 gallons per day per student. The total number of students per dwelling unit is estimated to be 0.4331 students/DU for elementary school (grades K-6).13 With a total of up to 2,623 dwelling units in the Puente Del Monte community, the estimated total elementary school student body is 1,136. This unit demand factor would reflect all administrative, teacher, student, cafeteria, and janitorial uses for the school, averaged on a per-student basis. The result is a forecast indoor demand of 12.7 acrefeet/year for the two proposed elementary schools, rounded up to 13 acre-feet/year for purposes of this WSA.
11 Zanjero, Inc. has performed several meter studies in California’s Central Valley. Specific small and large mixeduse commercial developments were analyzed and found to range from 0.78 af/ac/yr to 1.22 af/ac/yr for the total indoor and outdoor area (hard space such as parking and sidewalks). The majority of this use is from indoor needs, which do not significantly vary regionally between the Central Valley and the Salinas Valley. 12 This is an estimate of indoor use per acre derived from a 2015 study of school demand in Folsom, California. A 2016 review of school demands in El Dorado Hills, California confirmed these numbers for newer schools. 13 Based upon values from the Gonzales Unified School District Facilities Management Plan.
A.3.3 Light Industrial Indoor
The PDM community’s proposed Light Industrial area consists of 21 acres. Examples of permitted uses in this area include retail, appliance repair, laundromat, professional services/ office space, medical, laboratory, wholesale, and light industry uses such as contracting, limited manufacturing, paint supplies, janitorial services. The exact level of indoor water use in this portion of the community will depend on the specific businesses that occupy each parcel. For the purposes of this WSA, the indoor unit demand factor for this classification is estimated at 1 acrefoot/acre.
A.3.4 Highway Commercial Indoor
The PDMSP proposed 39 acres of Highway Commercial area which entails “commercial areas that cater to highway travelers and/or regional markets, including gas stations, big-box retail, fast-food restaurants, lumber yards, motels, auto malls, building contractor storage yards, and other uses that serve local and regional needs for goods and services.”14 This area is subject to a maximum Floor Area Ratio (FAR) of 0.5. Based upon meter studies conducted on existing highway commercial facilities elsewhere in California, coupled with the on-going commitment toward more efficient water use, the indoor unit demand factor for this classification is estimated at 1 acre-foot/acre for the purposes of this WSA.
A.3.5 Elementary School Outdoor
Quantifying outdoor water demands for schools depends on many factors including campus landscaping, size and type of play fields, student population, and other factors. Puente Del Monte’s proposed two 10-acre elementary schools are assumed to follow designs typical in the Salinas Valley. Turf play fields are expected to occupy 12.96 percent of the total schools’ area, or approximately 130,500 sf (2.99 acres) for both elementary schools combined. The remaining landscape area at each school will be trees and shrubs with lower water demands maintained by drip irrigation. The low water use landscaping is expected to occupy approximately 26 percent of the total schools’ area, or approximately 263,070 sf (6.03 acres). Using the MWELO formula, the total landscaping outdoor demand from the two elementary schools is estimated to be a total of 20.9 af/year. On average, the school sites are estimated to use 1.05 af/acre of total site area.
A.3.6 Parks and Open Space Outdoor
The PDM community includes several distinct outdoor landscaping areas including traditional parks and open space, a central drainage trail (greenway), and an agricultural buffer. 15 The
landscape architect for Puente Del Monte has provided estimates regarding the percentage of each acre that is hardscape, unirrigated drainage basins, or irrigated landscaping, and the percentage of irrigated area that is turf versus shrubs and trees.16 Appendix A of the PDMSP provides details on PDM’s landscaping direction and plant selection. 14 WHA et al. (2021) Puente Del Monte Specific Plan, page 2-6 15 More information on the agricultural buffer is presented in section A.4. 16 Personal communication, 4/14/22 email from Garett Bustos, Landscape Architect at Land Concern.
The primary assumptions used to estimate the outdoor demand for these features include:
The assumed reference evapotranspiration (ETo) – as discussed previously, an ETo of
52.5 inches per year is assumed.
Plant Factors (PF) – The evapotranspiration adjustment factor (ETAF) of 0.6 was used for turf play areas, and 0.3 for all other irrigated landscaping, which will be planted with low water use plants.
The estimated square footage of each type of planting within each land-use category (LA) These assumptions are combined in the following formula:
Demand = (ETo) (0.62) (PF x LA), where ETo is the reference evapotranspiration in inches per year, PF is the plant factor, LA is the landscape area, and IE is the irrigation efficiency for each planting type by land classification. 0.62 is a conversion factor to gallons. The resulting value is in “gallons per year,” which is converted to acre-feet per year Table A-3 presents the assumed percentages of irrigated land per each planting designation.

An additional 63 acres will be landscaped with drought tolerant plants that require irrigation during establishment only, which is expected to require 82 acre-feet/year for the first five years and zero applied water thereafter.
A.3.7 Other Non-Residential Outdoor (Landscaped Areas)
Other features include the landscaping for the elementary school, highway commercial and light industrial areas, and streetscape landscaping along the 66 acres of roads. The primary assumptions used to estimate the outdoor demand for these features are the same as those used to calculate outdoor demand for Parks and Open Space as described above in Section A.3.6.

*Agricultural Buffer includes 75 acres total, of which 63 acres will require applied water for establishment only.
Only 2.49 acres will require irrigation on an ongoing basis. Most of the remainder is hardscape or drainage basins.
A.4 OTHER MISCELLANEOUS USES
The PDM community has additional miscellaneous land uses with water demands, albeit only temporary demands. These uses have minimal impacts to the overall forecast water use due to their limited duration.
17 Irrigated area and turf area percentages are further discussed and detailed in the Puente Del Monte Specific Plan.
Construction Water
The PDM site would include site grading and infrastructure installation during early phases of construction that will require dust suppression and other incidental water uses. These would not continue beyond the construction phases of the PDM community. For purposes of identifying incremental water demands, construction water is conservatively assumed for purposes of this WSA to be 3 acre-feet per year (this is about 900,000 gallons – or about 225 fill-ups of a 4,000- gallon water truck per year).
Agricultural Buffer Establishment
The PDM Specific Plan includes “agricultural buffers” consisting of roadways, passive open space including trails, community gardens, stormwater quality basins, drainage features, and solar panel installations. The buffers are intended to provide a softer transition from the surrounding land uses into Puente Del Monte. Of the 63 acres in this land use category, 75 percent (47.25 acres) will be landscaped. These areas will be seeded with native or droughttolerant water use plants, with the majority of landscaping requiring irrigation during establishment only. A small subset of the Agricultural Buffer, called “enhance pedestrian nodes”, would have low water use plants using drip irrigation on an ongoing basis. The enhanced pedestrian nodes would be spread throughout the agricultural buffer, totaling 2.49 acres. The agricultural buffer is expected to require 1.31 acre-feet per acre during the first five years of establishment, then only 0.04 acre-feet/acre to irrigate the enhance pedestrian nodes every year thereafter. Note that the development of the agricultural buffer is phased, as shown below in Table A-6.
A.4 SUMMARY OF PUENTE DEL MONTE WATER DEMANDS
Combining the Puente Del Monte Specific Plan’s land use details and phasing with the demand factors presented in Table A-1 through Table A-5, the water demands for the PDM community from implementation to build-out can be estimated. Upon completion of buildout, the demands are conservatively estimated at 1,135 acre-feet of water annually, excluding considerations of non-revenue water (see below), and up to approximately 1,262 acre-feet of water annually when considering of non-revenue water (see Table A-6).
