• Residential Detached Low (RDL): Residential Detached Low land use is designated for detached homes of which net density is more than 1 unit per acre but less than 4 units per acre. The proposed residential detached low development is comprised of 139 units, approximately 55.2 net acres. The majority of the proposed development is located along Cochrane Road and Half Road, and the existing land use consists of residential and open space land uses. This development is consistent with the land use density documented in the City’s 2035 GP.
• Residential Detached Medium (RDM): Similar to Residential Detached Low land use, residential detached medium land use refers to land use for detached homes with net density falling in the range of 4 - 7 units per acre. The proposed residential detached medium developments consist of 7 projects, 63 units, which are primarily located in the middle and the northwest corner of the City, covering approximately 12.0 net acres area.
The existing land use currently consists of open spaces. These developments are consistent with the land use density documented in the City’s 2035 GP. • Residential Attached Low (RAL): The residential attached low development is defined as detached or attached homes with net density within the range of 6 - 12 units per acre. The proposed RAL development consists of 556 units, approximately 40.2 acres, of attached homes, along both sides of Highway 101. The proposed RAL development is primarily comprised of 4 projects, The existing land use currently consists of open space, commercial, and residential land uses. These developments are consistent with the land use density documented in the City’s 2035 GP.
• Residential Attached Medium (RAM): Within the City limits, along the west side of Highway 101, between Cochrane Road and West Dunne Avenue, locate the proposed residential attached medium developments, which are primarily comprised of attached homes (16 - 24 units/acre). This development includes 5 proposed projects, 655 units on top of approximately 35.7 net acres area. The existing land use currently consists of open space and residential land uses. These developments are consistent with the land use density documented in the City’s 2035 GP.
• Residential Attached High (RAH): The 2023 HE Update contains 1 residential attached high project (Monterey-First Community Housing (Magnolias)), which is located between Monterey Road and Del Monte Avenue. This project is approximately 1.5 net acres, includes 66 proposed units. The existing land use currently consists of commercial buildings.
It should be noted that this development has a differing net density (42.9 units/acre) than the land use designation documented in the 2035 GP (Mixed Use Flex, 7 - 24 units/acre).
Therefore, this project is categorized as RAH land use (attached homes, 24 - 46 units/acre). The increase in land use net density is expected to result in higher water

demand than the projection documented in the 2020 UWMP, which is discussed in detail in Section 2.
• Mixed Use (MU): Mixed use is designated for attached homes mixed with retail, office, services land use, and the net density shall be consistent with the City’s Down Town Specific Plan. The proposed mixed use development consists of 4 projects, including 117 units (approximately 6.4 net acres), along the west side of Monterey Street, within the downtown area. This development is consistent with the land use density documented in the City’s 2035 GP.
• Mixed Use Flex (MU-F): The 10 proposed mixed use flex is located at different sites within the City’s SOI boundary, including 750 units (approximately 42.9 net acres) was documented in the 2023 HE Sites. Note that, the proposed Monterey-Kerley (DeNova Homes) development site is documented as 4.6 acres on the City’s website (http://www.morgan-hill.ca.gov/2263/Monterey-Kerley-DeNova-Homes) and geodatabase provided by City staff, while it is listed as 1.05 acres in the 2023 HE Sites. This project site area of 4.6 acres has been confirmed by City staff. Therefore, in this report, 4.6 acres is used as the proposed DeNova Homes area, which will result in 46.5 net acres of MU-F land use in total.
Though the primary uses are similar to MU, the net density range is designated as 7 - 24 units per acre in the 2035 GP for Mixed Use Flex land use. This development is consistent with the land use density documented in the City’s 2035 GP.
1.4 Opportunity Sites
The proposed housing development opportunity sites are located inside the existing City limits as defined in the 2021 WSMP, as shown in Figure 1; while approximately 131.2 acres of development are within the Coyote Valley subarea and the rest approximately 70.8 acres of development located on top of Llagas groundwater subbasin. The existing land use of this Project consists of residential, commercial, and open space land uses. The City’s existing General Plan land use map designates the project sites as various land uses, including residential and mixed use types.
The proposed net density for the No.14 project (Monterey-First Community Housing (Magnolias)) site is higher than the density designated for this parcel in the 2035 GP, thus, the land use shall be Residential Attached High based on the proposed density. Besides, the area of DeNova Homes should be 4.6 acres rather than 1.05 acres as documented in the 2023 HE Sites. The proposed future land use inventory by groundwater subbasin summarized in Table 1 was developed from 2023 HE Opportunity Sites information provided by City staff, which is included in Appendix A.

1.5 Proposed Project Phasing
Law
This Project consists of future residential developments to meet the increasing housing needs within the City. A large portion of this Project’s proposed land uses (approximately 65.0%) locate on top of the Coyote Valley subarea, which is a part of the Santa Clara subbasin, and the rest is primarily above the Llagas subbasin.
The proposed future development of this Project was intentionally phased in order to adequately reflect the real-world construction process and estimate the demand more accurately. The 8-year development of this Project was phased in 5-year increments and the proposed developments were divided by different project sites and land use types.
It should be noted that the actual timing of construction for the proposed developments is subject to change, and might be different from this WSA. While the projected demands cover all construction work of the proposed developments, is anticipated to be completed within the 23- year planning horizon of this WSA.
2.0 PROJECTED WATER DEMANDS
Domestic water demand unit factors are coefficients commonly used in planning level analysis to estimate future average daily demands for areas with predetermined land uses. The unit factors are multiplied by the number of dwelling units or net acreages for residential categories, and by the net acreages for non-residential categories, to yield the average daily demand projections.
2.1 Water Use Demand Factors
There are several methods for developing the unit factors. The projected water demands in the currently adopted 2021 WSMP were based on land use demand factors. To ensure consistency with the City’s Master Plans, in this assessment, the unit water demand factors are intentionally kept to be consistent with the City’s WSMP. These demand factors account for the City’s continued water conservation efforts and future water conservation targets implemented by the City. The water demand unit factors are documented in Table 2. 10631 (f) …The urban water supplier shall include a detailed description of expected future water projects and programs…that the urban water supplier may implement to increase the amount of the water supply available to the urban water supplier in normal and single dry water years and for a period of drought lasting five consecutive water years.. The description shall identify specific projects and include a description of the increase in water supply that is expected to be available from each project. The description shall include an estimate with regard to the implementation timeline for each project or program.

2.2 Proposed Project Water Demand Projections
The development information provided by City staff identified the project site would develop as a combination of residential and mixed use land use types. It is assumed that the land use based on the received 2023 HE Sites will supersede the land use designations in 2035 GP. Additionally, the 2023 HE Sites will be used for estimating the effects on the water supply. The phased water demand projection results of this Project from initiation to the buildout are documented in Table 3 and documented below.
The master plans used for preparing this WSA have different planning horizons, which are depicted in Figure 3. It should be noted that the City will reach the buildout condition in the year 2038 in the 2021 WSMP, which was prepared based on the land use designation from 2035 GP, therefore the projected future demand after 2038 is anticipated to be consistent. For the purpose of this assessment, the future demands baseline is consistent with the 2020 UWMP, which was prepared based on the estimated population, to account for the City’s potential growth after 2038. • Existing Demand – From the City’s 2021 WSMP, the existing total demand within the city limits is documented as 6,329,210 gallons per day (gpd, or approximately 7,094 Acre Feet per Year (AFY) (Table 4).
• Future Water Demand – Santa Clara Subbasin (Coyote Subarea). The residential water demands of the proposed future development within the Coyote subarea at the end of the year 2031 are estimated at approximately 64.9 AFY for RDL, approximately 4.1 AFY for RDM, approximately 77.5 AFY for RAL, approximately 50.2 AFY for RAM. The water demand for the proposed future MU-F development within the Coyote subarea is estimated to be approximately 28.1 AFY. The total water demand of the Project’s future Coyote subarea development is estimated at 224.8 AFY in the buildout of the 2023 HE Update.
• Future Water Demand – Llagas Subbasin. The residential water demands of the proposed future development within the Llagas subbasin at the end of the Year 2031 are estimated at 2.9 AFY for RE, approximately 18.8 AFY for RDM, approximately 8.0 AFY for RAL, approximately 41.7 AFY for RAM, and approximately 5.4 AFY for RAH. The nonresidential water demands for the proposed future development within the Llagas subbasin are estimated to be 9.6 AFY for MU and approximately 44.3 AFY for MU-F. The total water demand of the Project’s future Llagas subbasin development is estimated at 130.7 AFY in the buildout of the 2023 HE Update. Table 4 identifies the net increase in demands, between the 2020 UWMP and this WSA, at 3 AFY. This net increase is resulting from a single proposed development, Monterey-First Community Housing (Magnolias, Map ID 14), which exceeded the previous general plan assumptions. • Future Water Demand – Other Developments. The water demands from future developments that are not included in the 2023 HE Update are calculated based on the
April 2022 12 WSA for 2023-2031 Housing Element Update
Akel Engineering Group City of Morgan Hill
total projected future water demands documented in the City’s 2020 UWMP subtracting the estimated future demand from the Project. The computed results are summarized in Table 4.
3.0 PROJECTED WATER SUPPLY
This section characterizes the intended water supply that will be used to serve the estimated water demands as detailed in Section 2.
3.1 Groundwater Basin
Law
The City is located above two subbasins, the Santa Clara subbasin of the Santa Clara Valley Groundwater Basin (Basin 2-009) and Llagas subbasin of the Gilroy - Hollister Groundwater Basin (Basin 3-003), and is depicted in Figure 1. Both groundwater basins have been identified by DWR as “high” priority basins. The Santa Clara subbasin is delineated into two subareas, the Santa Clara Plain and Coyote Valley, by the Santa Clara Valley Water District, the Groundwater Sustainability Agency (GSA) of Santa Clara, and Llagas subbasins. A majority of the existing City limits are within the Llagas subbasin and the northwest part is located above the Coyote Valley subarea. The Santa Clara Valley Water District (Valley Water) has updated its 2021 GMP, which also satisfies the objectives of the Sustainable Groundwater Management Act (SGMA). Therefore, Valley Water’s 2021 GMP serves as an alternative plan to the required Groundwater Sustainability Plan (GSP).
According to Valley Water’s 2020 RUWMP, local groundwater resources make up the foundation of Santa Clara County’s water supply. The groundwater is pumped from the subbasins by retail water suppliers, agricultural users, and private well owners to support municipal, industrial, agricultural, and domestic uses. Although most of the groundwater pumped is a result of Valley Water managed recharge programs, the subbasins are also recharged by the infiltration of rainfall and natural seepage through local creeks and streams. In addition, the groundwater subbasins serve as an extensive conveyance network, allowing water to move from the recharge areas to individual groundwater wells. The groundwater subbasins provide some natural filtration of surface water as it flows through the soil and rock. Unlike surface water, most groundwater in the county can be served by water retailers without additional treatment beyond disinfection. Lastly, the groundwater subbasins provide water storage, allowing water to be carried over from the wet season to the dry season and even from wet years to dry years. 10631. (b)(4) If groundwater is identified as an existing or planned source of water available to the supplier, all of the following information shall be included in the plan:
(B) A description of any groundwater basin or basins from which the urban water supplier pumps groundwater.

The Llagas subbasin and the Coyote Valley subarea are monitored and addressed by Valley Water. The January 2021 Groundwater Condition Report from Valley Water notes that groundwater levels were about the same as the 5-year average in the Coyote Valley subarea but about 13 feet lower than the 5-year average in the Llagas subbasin. Additionally, groundwater pumping for 2020 was above the 5-year average for both subbasins. However, groundwater recharging for 2020 was below the 5-year average for both subbasins.
3.2 Water Rights
Examples of legal factors that could impact the supply reliability of a water distribution system include pumping limitations in adjudicated groundwater basins and surface water contracts.
Historically, groundwater has been the sole source of water supply within the City, and there are no new sources of supply currently planned. Groundwater is extracted from the Coyote Valley subarea of Santa Clara Valley Groundwater Basin and Llagas subbasin of the Gilroy-Hollister Groundwater Basin. These groundwater basins and subbasins are not adjudicated basins and no current legal factors are expected to limit the availability of supply.
According to the City’s 2021 WSMP, sixteen groundwater wells serve as the domestic water source of supply. Based on the locations of the existing groundwater wells, it is assumed that currently the City is supplied by groundwater from both the Coyote subarea and Llagas subbasin.
3.3 Water Supply Reliability
Law
There are two aspects of supply reliability to be considered. The first relates to immediate service needs and is primarily a function of the availability and adequacy of the supply facilities. This aspect is considered for emergency reliability. The second aspect is climate-related and involves the availability of water during mild or severe drought periods. Due to no non-potable water demand projected from the City’s 2023 HE Update, only groundwater supply will be discussed in this WSA.
3.3.1 Groundwater Supply Facilities
The City currently uses local groundwater as its sole source of potable water supply. Water supply for the municipal water system is extracted from underground aquifers via sixteen existing groundwater wells located throughout the City.
10631 (b) Identify and quantify, to the extent practicable, the existing and planned sources of water available to the supplier over the same five-year increments described in subdivision 10631(a).
(4) (Provide a) detailed description and analysis of the amount and location of groundwater that is projected to be pumped by the urban water supplier. The description and analysis shall be based on information that is reasonable available, including, but not limited to, historic use records.
April 2022 17 WSA for 2023-2031 Housing Element Update
Akel Engineering Group City of Morgan Hill
The City’s 2021 WSMP recommends the construction of six future groundwater wells to meet supply requirements as demand increases at the end of buildout (the year 2038). The City’s storage facilities also enhance long-term reliability. These facilities provide emergency storage sufficient to handle the service area needs during power outages or other emergencies. Adding supply and distribution system enhancements will also add reliability through redundancy. This WSA assumes the supply facilities will be improved and constructed as recommended in the City’s 2021 WSMP.
3.3.2 Subbasins Sustainable Yield
Law
The 2021 GMP describes historical levels within the Santa Clara subbasin, which includes the Santa Clara Plain and Coyote Valley subareas, as generally consistent. Due to continuous groundwater monitoring and recharge in both subareas, groundwater levels have historically been consistent and shown a quick recovery after the 2012 - 2016 statewide drought. However, The January 2021 Groundwater Condition Report from Valley Water notes that the groundwater levels in Llagas subbasin were about 13 feet lower than the 5-year average in the Llagas subbasin.
Additionally, groundwater levels in the Llagas subbasin and the Coyote Valley subarea are highly dependent on rainfall levels, which produce fluctuations in water levels during years of high or low rainfall. Inconsistent water levels due to drought have the potential to impact the supply available to the City.
SGMA defines the sustainable yield as the maximum quantity of water, calculated over a base period representative of long-term conditions in the basin and including any temporary surplus, that can be withdrawn annually from a groundwater supply without causing an undesirable result.
However, Valley Water does not rely on the estimated maximum water production value for longterm water supply planning due to the particular characteristics of the subbasins they are managing.
Instead of providing the sustainable yield of each subbasin, Valley Water implements both shortterm and long-term groundwater managements to maintain sustainable conditions of subbasins, such as recommending short-term water use reduction in accordance with the Valley Water’s Water Shortage Contingency Plan (WSCP), annual evaluations of groundwater storage and water supply risks, recharge of imported water and in-lieu recharge activities.
The total of natural groundwater recharge, local surface water, Valley Water Central Valley Project (CVP) deliveries, and recycled water supply excluding the wastewater treatment plant (WWTP) 10631 (b)(1) A detailed discussion of anticipated supply availability under a normal water year, single dry year, and droughts lasting at least five years, as well as more frequent and severe periods of drought, as described in the drought risk assessment. For each source of water supply, consider any information pertinent to the reliability analysis conducted pursuant to Section 10635, including changes in supply due to climate change.

utility water is regarded as the available supply for the consumers within the area. The projected future supply data of individual subbasins beneath the Project’s proposed developments are provided by City staff and Valley Water staff, the results are summarized in Table 5.A and 5.B and briefly described as follows:
• Llagas Subbasin: Approximately 36% of the proposed future housing development is located on top of the Llagas subbasin. The projected annual natural groundwater recharge to Llagas subbasin is approximately 22,478 AFY from 2025 to 2045, per modeling data provided by Valley Water staff. The available supplies of the Llagas subbasin are projected to be 47,319 AFY, 47,580 AFY, 48,373 AFY, 48,188 AFY, and 48,342 AFY in the year 2025, 2030, 2035, 2040, and 2045, which are summarized in Table 5.A. • Coyote Valley Subarea: On top of this subarea has approximately 127.68 acres of proposed future housing development. The projected available supply of the Coyote Valley subarea in the year 2025, 2030, 2035, 2040, and 2045 are approximately 12,465 AFY, 13,162 AFY, 13,764 AFY, 14,313 AFY, and 14,650 AFY, respectively, per modeling data provided by Valley Water staff, as documented in Table 5.B.
4.0 SUPPLY SUFFICIENCY ANALYSIS
Law
Pursuant to California Water Code § 10910, the water supply assessment for the project shall include a discussion with regard to whether the total projected water supplies available during normal, single dry, and multiple dry water years during a 23-year projection will meet the projected water demand associated with the proposed Project.
In this section, a detailed analysis of the water supply and demand comparison will be provided to determine the groundwater supply sufficiency within the Project’s proposed future developments, assuming the DeNova Homes project site is 4.6 acres and the rest of the Project develops as the 2023 HE Sites received from City staff.
Based on the data of the historical water use and supply data under different conditions prepared by Valley Water staff, and the City’s 2020 UWMP prepared by Akel Engineering Group, the supply projections for the 2023 HE Update in this WSA were calculated by adding up the projected 10635 (a) Every urban water supplier shall include, as part of its urban water management plan, an assessment of the reliability of its water service to its customers during normal, dry, and multiple dry water years. This water supply and demand assessment shall compare the total water supply sources available to the water supplier with the total projected water use over the next 20 years, in five-year increments, for a normal water year, a single dry water year, and multiple dry water years. The water service reliability assessment shall be based upon the information compiled pursuant to Section 10631, including available data from state, regional or local agency population projections within the service area of the urban water supplier.

available supplies within each subbasin (subarea) under different year types extracted from the South County Supply Document, as documented in Tables 5.A, 5.B, 6.A, 6.B, 7.A, 7.B. • Normal Year: The normal year is a year that represents the median runoff levels from precipitation, as well as the same general pattern of runoff. The supply quantities would be similar to historical average supplies. Within the Llagas subarea, the projected available supply is estimated at 47,319 AFY, 47,580 AFY, 48,373 AFY, 48,188 AFY, and 48,342 AFY in the year 2025, 2030, 2035, 2040, and 2045. The projected total water demand of the Project is estimated as 131 AFY, which is accounted for a projected subbasin-wide demand of 47,372 AFY, in 2045 under normal year conditions, which are documented in Table 5.A. Within the Llagas subbasin, the available water supply is expected to be able to meet the projected future water demand during normal years. Similarly, in the Coyote Valley subarea, the available water supplies are estimated as 12,465 AFY, 13,162 AFY, 13,764 AFY, 14,313 AFY, and 14,650 AFY, for every five years from 2025 to 2045. The projected water demand of the Project and subarea-wide demand are estimated as 225 AFY and 13,025 AFY, respectively, as documented in Table 5.B. From the results, the subarea’s future demand could be satisfied by the subarea-wide available supply during normal years.
• Single-Dry Year: The single dry year is defined as the individual year with the lowest usable water supply and slightly higher water demands. From the City’s 2020 UWMP, 1977 is the single dry year used for analysis. Within the Llagas subbasin, the projected available supply is estimated at 36,424 AFY, the projected water demand of the Project is estimated as 131 AFY, which is accounted for a total demand of 47,372 AFY, in 2045 under single dry year conditions, which are documented in Table 6.A. Similarly, for the Coyote Valley subarea, the available water supply, water demand of the Project, and total projected demand in the year 2045 are estimated as 14,442 AFY, 225 AFY, and 13,025 AFY, respectively, as documented in Table 6.B. For both subbasins, due to potential water supply reductions, the projected water demand may exceed the available supply amount for some single dry years during the planning period.
Pursuant to Valley Water’s 2020 RUWMP, Valley Water would store excess wet year supplies and draw on these reserve supplies during the dry year(s). And in the City’s 2020 UWMP, water shortage levels shall be declared based on the water supply conditions (Appendix B) and implement water usage reduction actions pursuant to the Water Shortage Contingency Plan (Appendix C) to promote water conservation. In this way, the limited water supply may be sufficient to meet the reduced water demand. • Multiple Dry Years: Similar to single-dry year, multiple dry years is defined as the five consecutive years with the lowest usable water supply and slightly higher water demands, which are documented as the year 1988, 1989, 1990, 1991, 1992 in the City’s 2020 UWMP. The projected water supply and demands are summarized in Table 7.A and Table
7.B.

Generally, the supply system is observed to be sufficient to meet the demand requirement in some dry years in prolonged droughts. But it might be not able to satisfy the demand all cycle long. However, with the Water Shortage Contingency Plan taking effect, and the waste and unreasonable use of water being prevented, the available water supply may meet the reduced water demand during droughts.
Comparing the projected water supply availability and water demands, this water supply assessment indicates that the water supply from the subbasins is sufficient to meet the water demands of the proposed future developments within the City limits, under normal year conditions, over the next 23 years. However, in a single dry year or consecutive dry years, the projected demand is expected to exceed the system supply. Therefore, water conservation actions and procedures, such as declaring drought and calling for short-term water use reductions, are necessary for maximizing the use of available supplies in order to meet the potential shortage, more details are discussed in the City’s 2021 WSCP.
It should be noted that this supply shortage during single dry and consecutive dry years was condition present in the 2020 UWMP, and not caused by this Project.
5.0 SUMMARY AND CONCLUSIONS
The land use projections in this report were based on the information contained in the City’s 2023 HE Sites (Appendix A). They were consistent with the City’s 2035 GP (except for proposed development No. 14), and phased in 5-year increments and through the project horizon year of 2045, with the very valuable assistance of City of Morgan Hill staff. A summary of the findings include:
5.1 Land Use
The proposed future development within the SOI of the City of Morgan Hill consists of approximately 4.6 acres (4 units) of Residential Estate, approximately 55.2 acres (139 units) of Residential Detached Low, approximately 12.0 acres (63 units) of Residential Detached Medium, approximately 40.2 acres (556 units) of Residential Attached Low, approximately 35.7 acres (655 units) of Residential Attached Medium, approximately 1.54 acres (66 units) of Residential Attached High, approximately 6.4 acres (117 units) of Mixed Use, and approximately 42.9 acres (750 units) of Mixed Use Flex.
5.2 Water Demands
According to the City’s 2023 HE Update (being prepared during this WSA), the proposed housing development is expected to be constructed by the end of year 2031. Therefore, the projected demand from this Project shall be consistent from year 2031 to the planning horizon of this WSA, which is year 2045. At the end of the 23-year period, the projected water demands from this
April 2022 27 WSA for 2023-2031 Housing Element Update
Akel Engineering Group City of Morgan Hill
Project within the Coyote Valley subarea and Llagas subbasin are estimated at approximately 225 AFY and 131 AFY, respectively, and the total demand is estimated to be approximately 356 AFY.
Table 3 provides a detailed listing of anticipated projects, within each groundwater basin, with phased demand projections. Table 4 provides a summary of the projected phased demands, and a comparison between this WSA, the 2020 Urban Water Management Plan (UWMP), and the 2021 Water System Master Plan. It should be noted that Table 4 identifies the net increase in demands, between the 2020 UWMP and this WSA, at 3 AFY. This net increase is resulting from a single proposed development, Monterey-First Community Housing (Magnolias, Map ID 14), which exceeded the previous general plan assumptions.
5.3 Water Supply
Based on the Valley Water 2020 UWMP and the South County Supply projections provided by City staff and Valley Water staff, the total water supply within each subbasin consists of natural groundwater recharge, local surface water, Valley Water CVP deliveries, recycled water supply (excluding WWTP utility water), where available. Therefore, in the year 2045, under normal year conditions, the projected water supply availabilities of the Llagas subbasin and Coyote Valley subarea are approximately 48,342 AFY and 14,650 AFY, respectively (Tables 5.A and 5.B).
5.4 Water Supply Sufficiency
Water supply sufficiency is compared during normal years, as well as during dry years.
Normal Year. Comparing the projected water supply availability and water demands, this water supply assessment indicates that the water supply from the subbasins is sufficient to meet the water demands of the proposed future developments within the City limits, under normal year conditions, over the next 23 years (Tables 5.A, 5.B).
Dry Years. During a single dry year or consecutive dry years, the projected demands are expected to exceed the system supply in the 25-year window (Tables 6.A, 6.B, 7.A, 7.B).
Therefore, pursuant to the City’s 2020 UWMP and WSCP, water conservation actions (Appendix C) and procedures, such as declaring water shortage levels (Appendix B) and calling for shortterm water use reductions, are necessary for maximizing the use of available supplies in order to meet the potential shortage. It should be noted that this supply shortage during single dry and consecutive dry years was condition present in the 2020 UWMP, and not caused by this Project.
5.5 Conclusions
In conclusion, the analysis and findings in this WSA indicate the following:
• The net increase in demands, between the 2020 UWMP and this WSA, is at 3 AFY.

It is not intended to serve as legal advice regarding any jurisdiction's specific policies or any proposed housing development project. Local staff should consult with their city attorney or county counsel when determining the applicability of these provisions to any proposed housing development project in their jurisdiction.
The “Builder’s Remedy” and Housing Elements
There have recently been press reports regarding the so-called “Builder’s Remedy” that can be used to avoid local zoning requirements when a locality’s housing element does not substantially comply with state law. These reports have stated that, if a locality has a noncompliant housing element the city or county must approve the housing development project, regardless of the local zoning.
The “Builder’s Remedy” arises from the Housing Accountability Act (Government Code Section 65589.51 ; the HAA). This
paper describes the provisions of the HAA that constitute the “Builder’s Remedy” and how they may apply to a proposed housing development project.
How Does the “Builder’s Remedy” Work?
The HAA requires that cities and counties make one of five findings to deny, or to apply conditions that make infeasible, a housing development project “for very low, low- or moderate-income households” or an emergency shelter. (Section 65589.5(d).) A housing development project with 20 percent of the total units available to lower income households or with all of the units available for moderate or middle income households may qualify as housing “for very low, low- or moderate income households” (see detailed description below). The five findings which would allow denial of an eligible project can be summarized as follows:
1. The city or county has met or exceeded its Regional Housing Needs Allocation (RHNA) for the proposed income categories in the development.
2. The housing development or emergency shelter would have a specific adverse impact on public health and safety, and there is no way to mitigate or avoid the impact without making the development unaffordable. The impact must be based on objective, written public health or safety standards in place when the application was deemed complete.
3. The denial or condition is required to meet state or federal law, and there is no feasible method to comply without making the development unaffordable.
4. The project is proposed on land zoned for agriculture or resource preservation that is surrounded on at least two sides by land being used for agriculture or resource preservation or there are not adequate water or sewage facilities to the serve the project.
1 All future references are to the Government Code unless otherwise specified.
Regional Housing Technical Assistance Program
2 5. The project is inconsistent with both the zoning ordinance and the land use designation as specified in any general plan element. However, a city or county cannot make this finding if it has not adopted a housing element in substantial compliance with state law.
If a locality has not adopted a housing element in substantial compliance with state law, developers may propose eligible housing development projects that do not comply with either the zoning or the general plan. The term “Builder’s Remedy” is used to describe the situation where a local agency may be required to approve an eligible housing development project because it cannot make one of the other four findings.
Are Projects Using the “Builder’s Remedy” Exempt from CEQA Review? The HAA contains no exemptions from the California Environmental Quality Act. The HAA states specifically that nothing relieves the local agency from making the required CEQA findings and otherwise complying with CEQA. (Section 65589.5(e).) A project may be exempt from CEQA under other provisions of CEQA, other state laws, or the CEQA Guidelines.
When Does a Housing Element No Longer Comply with State Law? Is There a Grace Period If the Housing Element Is Not Adopted by the Due Date? Housing elements are required to comply with current state housing element law on the established due date (January 31, 2023 in the ABAG region). State law has changed significantly since fifth cycle housing elements were adopted, and it would be unlikely that a fifth cycle housing element would substantially comply with current state law. If a sixth cycle element has not been adopted by the due date, the housing element would likely be out of compliance with state law until a complying sixth cycle housing element is adopted. There is no grace period, even for the period when a housing element is being reviewed by the Department of Housing and Community Development (HCD).
HCD approval is not required for a housing element to be found substantially compliant with state law. State law provides that a city or county may adopt its own findings explaining why its housing element is substantially compliant with state law despite HCD’s findings. (Section 65585(f).) However, HCD is authorized to refer agencies to the Attorney General if it finds a housing element out of compliance with state law. (Section 65585(j).) Are a Local Agency’s Development Standards Null and Void If the Housing Element is Not in Compliance with State Law?
No, the local agency’s development standards are not null and void if the housing element is not in substantial compliance with state law. The “Builder’s Remedy,” however, may require a local agency to approve an eligible housing development project despite its noncompliance with local development standards. Conversely, other projects may be challenged because a finding of general plan consistency cannot be made if the general plan is out of compliance with state law.
What Projects Are Eligible to Use the “Builder’s Remedy”? The “Builder’s Remedy” applies only to a housing development project “for very low, low- or moderate-income households” and to emergency shelters. The HAA defines a “housing development project” as either:
• Residential units only;
• Mixed-use developments with at least two-thirds of the square footage designated for residential use; or
Regional Housing Technical Assistance Program
3 • Transitional housing or supportive housing.2 (Section 65589.5(h)(2).) “Housing for very low, low-, or moderate-income households” includes either:
• 20% of the total units sold or rented to lower income households; • 100% of the units sold or rented to moderate income households; or • 100% of the units sold or rented to middle income households.3 Monthly housing costs for lower income households cannot exceed 30 percent of 60 percent of median income, adjusted for household size, and the units must remain affordable for 30 years. Monthly housing costs for moderate income households cannot exceed 30 percent of 100 percent of median income. There are no standards in the HAA for housing costs for middle income households. (Sections 65589.5(h)(3), (h)(4).) An emergency shelter is housing with minimal supportive services for homeless persons that is limited to occupancy of six months or less by a homeless person. No individual or household may be denied emergency shelter because of an inability to pay. (Section 65582(d); Health & Safety Code Section 50801(e).)
2 As defined in Section 65582.
3 Those earning no more than 150 percent of median income.

2 • Goes into effect July 1, 2023
• AB 2011 and SB 6 permit residential development on sites currently zoned and designated for commercial or retail uses • AB 2011 creates a CEQA-exempt, ministerial approval
process for multifamily housing developments on sites within a zone where office, retail or parking are the principally permitted use
• Uses different qualifying criteria based on affordability and rental/owner projects
• Local inclusionary requirements prevail if greater affordability required
AB2011 & SB 6 –
Residential Development in
Commercial Zones
3 • SB 6 may be either a 100-percent residential project or a mixed-use project where at least 50 percent is dedicated to residential uses
• Does not create a new process
