Agenda Item No.: 8.A Mtg. Date: 12/17/2020 TO: HONORABLE CHAIR AND MEMBERS OF THE PLANNING COMMISSION FROM: MEREDITH ELGUIRA, PLANNING DIRECTOR THRU: ELAINE JENG P.E., CITY MANAGER SUBJECT: RECOMMENDATION TO CITY COUNCIL APPROVAL OF RESOLUTION NO 2020-08 OF THE PLANNING COMMISSION OF THE CITY OF ROLLING HILLS, CALIFORNIA RECOMMENDING THAT THE CITY COUNCIL ADOPT AN ORDINANCE AMENDING TITLE 17 (ZONING) OF THE ROLLING HILLS MUNICIPAL CODE TO ADD CHAPTER 17.19 (OVERLAY ZONING DISTRICT – RANCHO DEL MAR HOUSING OPPORTUNITY OVERLAY ZONE) ESTABLISHING AN OVERLAY ZONE TO ACCOMMODATE HOUSING AND DETERMINING THE ORDINANCE AND ADOPTION OF THE INITIAL STUDY AND NEGATIVE DECLARATION, AND APPROVAL OF RESOLUTION NO. 2020-09 OF THE PLANNING COMMISSION OF THE CITY OF ROLLING HILLS, CALIFORNIA RECOMMENDING THAT THE CITY COUNCIL ADOPT GENERAL PLAN AMENDMENT NO. 20-01 TO THE CITY OF ROLLING HILLS GENERAL PLAN, AN AMENDMENT TO THE GENERAL PLAN TO ADOPT THE LAND USE ELEMENT AMENDMENT AND LAND USE POLICY MAP AMENDMENT DATE: December 17, 2020 BACKGROUND: Pursuant to the California State Housing-Element Law, the City of Rolling Hills (City) is in the process of updating its Housing Element of the General Plan to address the planning period from 2014-2021. The City last adopted their 2014-2021 Housing Element of the General Plan on February 10, 2014, along with the associated General Plan Amendment. The City is currently moving forward with bringing the 4th and 5th cycles into compliance with the Housing Element Regional Housing Needs Assessment (RHNA) and is working with the California Department of Housing and Community Development (HCD) to also bring the 6th cycle into compliance. The update to the Housing Element of the General Plan includes identifying an opportunity site within the City that would accommodate and meet RHNA numbers as assessed by the HCD. 3

The update to the Housing Element of the General Plan includes a proposed Project that would establish a new overlay zone that would accommodate the existing uses on the site, as well as allow for new multi-family units to be developed. The proposed Project would also require the appropriate General Plan and Zoning Ordinance amendment and associate maps to reflect the creation of the new overlay zone. The zone change and new overlay zone will enable the City of Rolling Hills to start accommodating its RHNA allocations. A feasible site located at 38 Crest Road West at the southern end of the City has been selected to be utilized as the opportunity site for additional housing, including affordable housing, emergency shelters, and Single Room Occupancy Housing. In compliance with the California Environmental Quality Act (CEQA), the City of Rolling Hills prepared an Initial Study/Negative Declaration to analyze the potential environmental impacts resulting from the proposed Project. The City of Rolling Hills requests that the Planning Commission review the proposed Project and consider the Initial Study/Negative Declaration and all comments received from the public. CEQA CONSIDERATIONS Pursuant to the requirements of the California Environmental Quality Act (CEQA), an Initial Study/Negative Declaration was prepared in November 2020. The environmental analysis determined that the Project would not have a significant effect on the environment, therefore a Negative Declaration was prepared and circulated to the appropriate agencies for their review. CEQA guidelines require that local governments comply with Assembly Bill (AB) 52 to include California Native American Tribes in the decision-making process by notifying the associated local tribes of the Proposed Project. Local tribes have the opportunity to request consultation and provide recommendations for mitigation measures that would help to preserve any potentially impacted tribal and cultural resources resulting from the Project. The City sent out tribal consultation request letters to five local tribes on Friday, October 16, 2020, and one letter on Saturday, October 17, 2020. Local tribes have until January 21, 2021 to respond and request for consultation. As of December 15, 2020, no request for consultation has been received. DISCUSSION: Since 1969, the State of California has mandated that all cities and counties properly plan for the housing needs of all residents in their communities Local governments adopt Housing Elements as part of their General Plans to adequately address the housing needs and demands of Californians. Plans and regulatory systems defined in a Housing Element provide opportunities for housing development. An assessment of housing needs for each region is calculated and determined by the California Department of Housing and Community Development (HCD) for each new Housing Element cycle. Regional housing needs are divided by income levels and are based on demographic population from the California Department of Finance. The State of California is currently in its 6th Cycle of the Housing Element updates Statewide. 4

An approximately 31-acre site located at the southern border of the City has been designated as an opportunity site that would allow for the development of new housing units, including affordable housing, emergency shelters, and Single Room Occupancy Housing. The site would require changes to the General Plan Land Use Element, zone change and the creation of a new overlay zone to adequately accommodate for RHNA unit numbers. The zone change and new overlay zone will enable the City of Rolling Hills to accommodate its RHNA allocations under the 4th and 5th Cycle RHNA requirements, including accommodation of affordable housing units as well as emergency shelters and Single Room Occupancy Housing. The total number of units that will be accommodated “by right” under the 4th and 5th Cycles would be a total of 16units, including low income units and very low-income units. Additionally, the proposed Project would also allow for the continued use of the public facilities, schools and transportation facilities at the site. Though emergency shelters and Single Room Occupancy (SRO) residential uses are also currently permitted under the City’s Municipal Code and may be allowed in the future, these units will not be allowed to be counted as the total dwelling units required under the City’s Regional Housing Needs Allocation (RHNA) for all future Cycles. PROJECT SITE The approximate 31-acre site currently houses the Rancho Del Mar High School building, the Beach Cities Learning Center, and the Palos Verdes Peninsula Transit Authority (PVP Transit Authority). This parcel of land is owned by the Palos Verdes Unified School District (PVUSD) and has an existing school (Rancho Del Mar School) located at this site. However, the Rancho Del Mar School facility is not being utilized as a school site at the current time. Access to the Project site is through a private roadway that veers off Crest Road West. A few unpaved internal roadways traverse the site. The site slopes from east to west, from the Beach Cities Learning Center to the Palos Verdes Peninsula Transit Authority, with an approximate 38 feet drop from east end of the Project site. Vegetation on-site consists of a few trees around the existing buildings and a mix of grasses and paved areas. The portion of the PVP Transit Authority site is primarily paved, with few buildings, parking areas and storage buildings. The site is currently zoned Residential Agriculture Suburban-2-Acres (RAS-2) and has a General Plan Land Use designation of Very Low-Density Residential 2+ Net Acres. The Project site is surrounded by RAS-2 zones to the east and north of Crest Road and is bounded by the City of Rancho Palos Verdes to the west and south, with zoning designations of Residential Single Lot – 20,000 square feet. PROJECT COMPONENTS The proposed Project would establish a new mixed-use-multi-family overlay zone (Rancho Del Mar Housing Opportunity Overlay Zone) that would accommodate the existing uses on the site, as well as allow for new multi-family residential, emergency shelters, transitional and Single Room Occupancy housing units to be developed in the future. The proposed Project would require an amendment to the General Plan Land Use Element, amendments to the General Plan Land Use Map and Zoning Map, and amendments to the Zoning Ordinance text in order to reflect the new overlay zone. These changes would then allow for future construction of 16 clustered multi-family units, consistent with the 20 units/acre designation. 5

The proposed Project includes the following specific components: Preparation of a Negative Declaration for the General Plan and Zoning Amendment and associated map changes. Amendment to the General Plan Land Use Element to add new Overlay zone designation to be known as the Rancho Del Mar Affordable Housing Overlay Zone. The associated land use map is being amended to add the overlay to the 31-acre Palos Verdes Unified School District (PVUSD) site on Crest Road (also known as the Rancho Del Mar High School Site). The Overlay requires the allowable number of dwelling units on any site with this designation to be clustered at a minimum of 20 units per acre. Other amendments to the Land Use Element will be made as needed to recognize that multi-family uses are permitted and anticipated within this overlay area. Amendment to the Zoning Ordinance (Title 17 of the Municipal Code) and related zoning map to add the “Rancho Del Mar Affordable Opportunity Overlay Zone”. The City has one other overlay zone that has been adopted and mapped for an area of smaller lots and steep terrain. (See Rolling Hills Municipal Code Chapter 17.17 (Overlay Zoning District – 1 (OZD-1).) The number of units allowed by the “base” General Plan designation on this site must be clustered; in other words, the overlay allows 16 multi-family units on this site by right. The Project is currently not being developed with any structures at the site. The proposed overlay zone that would allow for the future addition of new multi-family units would also assist the City in meeting its future housing requirements mandated under the California Department of Housing and Community Development (CA HCD). The City of Rolling Hills will be able to accommodate its RHNA allocations, including accommodation of affordable housing units. The Overlay Zone will also accommodate emergency shelters and Single Room Occupancy Housing as part of the Housing Element Update. INITIAL STUDY/ NEGATIVE DECLARATION An Initial Study was prepared by the City to evaluate the environmental impacts resulting from the proposed Project. Since any development at this current time is not a component of the proposed Project, it was concluded that any proposed Land Use Element policy, map and text changes, Zoning Ordinance map and text changes, as well as the creation of a new overlay zone, will not have a significant effect on the environment and a Negative Declaration has been prepared. The purpose of the environmental review under the Initial Study/Negative Declaration (Rancho Del Mar Affordable Housing Opportunity Overlay Zone IS/ND) is to evaluate all the planning document level changes that are currently being proposed addition of a new overlay zone for the City, related changes to the City’s Zoning Ordinance and Map, and changes in the related General Plan Elements and Map). Future new housing projects that may result from these document level changes would require their own environmental reviews, before any development changes are approved for the Project site. The City will thus undertake the appropriate level of environmental review as Projects at this site are proposed and developed. 6

FISCAL IMPACT: None. RECOMMENDATION: Approve recommendation to the City Council approval of Resolution 2020-08 amending Title 17 (Zoning) of the Rolling Hills Municipal Code to add Chapter 17.19 (Overlay Zoning District – Rancho Del Mar Housing Opportunity Overlay Zone) and adopting Initial Study and Negative Declaration 2020-01, and Resolution No. 2020-09 adopting General Plan Amendment No 20-01 amending the Land Use Element and Land Use Map.

City of Rolling Hills Rancho Del Mar Affordable Housing Overlay Zone Initial Study/Negative Declaration CSG Consultants, Inc. P a g e | 6 November 2020 1.0 INTRODUCTION This document constitutes an Initial Study (IS) that evaluates the potential environmental effects of the City of Rolling Hills’ (City; Rolling Hills) proposed overlay zone at the property at 38 Crest Road West (Project; proposed Project), also known as the Palos Verdes Unified School District school site; the addition of a Mixed-Use Multi-Family Overlay Zone (Rancho Del Mar Affordable Housing Overlay Zone); all associated General Plan Land Use Element updates; as well as all related Zoning Ordinance and associated Map changes. The proposed Project would establish a new mixed-use, multi-family overlay zone that would accommodate the existing uses on the site, as well as allow for new multi-family units to be developed at a future date. The proposed Project would include :  The creation of a new overlay designation – Rancho Del Mar Affordable Housing Overlay Zone;  Amendments to the City’s General Plan Land Element and Map;  Amendment to the Zoning Ordinance (Title 17 of the Municipal Code) and related zoning map to add the new “Rancho Del Mar Affordable Housing Overlay Zone”. The City has one other overlay zone that has been adopted and mapped for an area of smaller lots and steep terrain. (See Rolling Hills Municipal Code Chapter 17.17 (Overlay Zoning District – 1 (OZD-1).) The number of units allowed by the “base” General Plan designation on this site must be clustered; in other words, the overlay allows 15 multi-family units on this site by right.  Preparation of an Initial Study/Negative Declaration (IS/ND) for the Proposed Project. The City is undertaking this Project as part of its Housing Element Update. The zone change and new overlay zone will enable the City of Rolling Hills to accommodate its RHNA allocations under the 4th and 5th Cycle RHNA requirements, including accommodation of affordable housing units as well as emergency shelters and Single Room Occupancy Housing. The total number of units that will be accommodated “by right” under the 4th and 5th Cycles would be a total of 15 units, including low income units and very low income units. Though emergency shelters and Single Room Occupancy (SRO) residential uses are also currently permitted under the City’s Municipal Code and may be allowed in the future, these units will not be allowed to be counted as the total dwelling units required under the City’s Regional Housing Needs Allocation (RHNA) for all future Cycles. Additionally, the proposed Project would also allow for the continued use of the public facilities, schools and transportation facilities at the site. The Project site is not currently proposed for development. The development of a new overlay zone, and all associated General Plan, Zoning Ordinance and Map changes are currently being undertaken by the City so as to provide the opportunity for additional housing on the site in the future. This document concludes that a Negative Declaration (ND) is the appropriate level of environmental review for the proposed Project. Therefore, the IS/ND has been prepared in accordance with Public Resources Code (PRC) Section §21000 et seq. and the California 13

City of Rolling Hills Rancho Del Mar Affordable Housing Overlay Zone Initial Study/Negative Declaration CSG Consultants, Inc. P a g e | 7 November 2020 Environmental Quality Act (CEQA), California Code of Regulations Section §15000 et seq. It evaluates the potential environmental effects associated with the proposed Project. 1.1 Background A jurisdiction’s General Plan is intended to maintain and augment its built and natural environments, as well as to provide a vision for future development. Its Zoning Ordinance is therefore one of its main tools to implement the jurisdiction’s land use policies and guide any development. Any changes to a jurisdiction’s land use may typically require changes
