RE: Subcommittee Report and Recommendation – Serra Capital Feasibility Study

SUMMARY
We provide a subcommittee report and recommend that the Town Council direct the Town Manager to enter into an agreement with Serra Capital for an initial high-level assessment of up to six potential types of sites for affordable housing in Town to advance our progress under our Housing Element. While this project would not exceed the Town Manager’s spending authority, we wanted to bring this item forward to keep the Town Council apprised of the subcommittee’s efforts.

SUBCOMMITTEE REPORT
Mary Hufty and Judith Hasko were appointed by the Town Council to conduct public outreach to identify potential sites as affordable housing locations within Portola Valley that may serve as alternative sites to Dorothy Ford Park and Open Space, pursuant to the Sunrise Provisions of the Town’s Housing Element.

The Process. Since then, we have identified or been contacted in connection with a number of good opportunities that we believe merit further engagement. The subcommittee has built upon the hard work already done by so many Town residents and consultants. as well as Town staff and Town Council, Commission and Committee members, including an exhaustive review of Town-owned properties and numerous public meetings. We have conducted our outreach with an open mind, recognizing that development may occur in a

Page 2 ends

variety of ways, as infill or as multifamily building projects and be supported by a variety of federal, state and local funding sources. We have made ourselves available to discuss any and all housing opportunities and have received and reviewed many sites, non-profit and for profit housing organizations, and interacted with dozens of residents and potential partners.

We have several viable opportunities we continue to explore which may have much less negative impact on the Los Trancos Creek Riparian Zone and the Alpine Scenic Corridor than development in Dorothy Ford Park and Open Space. We have also taken into consideration constraints deriving from the geologic conditions, and earthquake and fire hazards in our community. We have prioritized gaining the trust and respect of those with whom we have interacted through honest communication of risks, timelines, and the range of opportunities, and our need to preserve the values reflected in our General Plan. Moreover, we look forward to benefiting from the expertise of our new members of the Town’s Planning Department to push forward our outreach efforts.

Building a list of Potential Sites. More specifically, our subcommittee has been actively seeking out information on parcels that might be, or might become, available to support our updated Housing Element, including our RHNA commitments. We have held more than 30 meetings including dozens of to discuss opportunities with respect to over 15 parcels. Mary personally has made over 20 individual site visits. Our efforts are not complete, and we remain open to outreach by any members of our community that have such information. We appreciate the engagement by a broad range of community members in this respect.

We view our task as creating a shortlist of more likely sites for potential housing that will be evaluated further by an ad hoc committee, and then staff, the Planning Commission and Town Council, as applicable, pursuant to the Town Council’s approved Post-Adoption Plan.

By its nature, our effort entails making contact with parcel owners who may or may not be interested in supporting our Housing Element through some arrangement regarding their parcel. We believe that our initial outreach critically depends on people feeling free to discuss their views without committing to a particular outcome at an early stage. As such, optimizing the potential success of our efforts requires us to have preliminary discussions in confidence.

As specific discussions evolve, we expect that parcel owners remaining interested in potentially participating in supporting our Housing Element will agree to engage in more public discussions as the Town refines its analyses. We expect that moving forward with any such opportunities with respect to specific parcels will require disclosure of much more information before the Town can take any action. As such, we have served as initial “scouts” for Sunrise Provision opportunities. We are not screening out opportunities and we are not making any advanced planning efforts for specific sites.

RECOMMENDATION
The Need for a Site Evaluation Framework. In the course of our work, we began to seek input from various professionals with experience in funding and carrying out development of sites for affordable housing to understand better what factors will render a site suitable for supporting our Housing Element. Specifically, we wanted to come up with a framework to

Page 9 of 148 ends

Page 3 ends

understand potential financial and practical factors that might impact building on, for example, a smaller site where the parcel owner may be willing to have a limited number of units of workers’ housing developed, and a larger parcel that at least theoretically, could support a greater number of units to allow us to modify plans to develop Dorothy Ford Park and Open Space. In short, we realized it would be helpful to flesh out a few working examples of potential building approaches for smaller and larger parcels in Town to help us focus on the highest value, and most available, types of parcels, understanding that no one site would be a perfect alternative.

This set of working examples was not intended to serve as a comprehensive analysis of specific sites or to select which financial vehicles would be best for supporting our Housing Element. Those steps will be the subject of other of our Housing Element efforts and future public discussions. The idea of creating the working examples derived from some preliminary discussions with Serra Capital, which is one among several sources of expertise we have engaged with, and which has a team with extensive experience in funding vehicles for building housing, including through affordable housing organizations.

Serra Capital’s Role. Serra Capital has familiarity with Portola Valley as its representatives have attended Stanford and have operated in the Bay Area. We enclose some information on their background: Serra principal David Kelly has been a leader in affordable housing nationally for over 30 years, responsible for development of over 12,000 units. His accomplishments in this role led to his appointment as Chairman of the Teacher Retirement System of Texas from 2007 to 2017. In the Bay Area, representative projects the principals have worked on include Mandela Station (West Oakland – 240 affordable units), Stanford Affordable (Palo Alto – 70 units), Rebuild Potrero (San Francisco – 1,600 affordable/mixed income units, and McArthur Station (Oakland – 1,000 mixed income units including 100 affordable).

Serra has developed a credit tenant lease program (an alternative to municipal bonds) for potential use in funding such housing efforts, and as a result has developed a team with expertise evaluating financing options for housing efforts. Through our initial conversation, Serra and the subcommittee agreed that developing a set of working examples could inform and progress the subcommittee’s efforts to identify sites that potentially could meet our Housing Element commitments.

To this end, we discussed with Serra their performing a high level review of physical capacity and financial feasibility of sites having certain general characteristics in Town, and then provide a report on the viability or special concerns with respect to such theoretical sites. They do not typically perform this type of study but are willing to do it at what we understand is a very reasonable cost given our special circumstances.

To be clear, while Serra offers a financial product that may be considered for funding the Town’s affordable housing needs in the future, at the moment, the subcommittee proposes only to engage Serra to conduct an initial feasibility assessment of housing sites to inform practical considerations for site identification for our process overall, regardless of whether the Town Council later decides this financial instrument is suitable for our needs. As a Town,

Page 10 of 148 ends

Page 4 ends

this analysis will serve us and the potential property owners who may contribute to our Housing Element efforts, by helping to refine what is feasible to build in sites having certain characteristics.

The Reason for Engaging Serra Now. The subcommittee is concerned that if we do not avail ourselves of some version of this type of analysis, we will continue to operate in a theoretical space that does not advance our Housing Element in a timely manner.

Additionally in our outreach with respect to a few parcels, parcel owners have indicated that this type of analysis will help their own evaluation of the opportunity to support our Housing Element. Such parcel owners want to remain anonymous at this point but should they remain interested in engaging with the Town in our Sunrise Provision efforts, know that a public discussion and disclosure of details will be necessary.

Our recommendation is to take advantage of obtaining a more informed framework for our affordable housing efforts soon, to facilitate the considerable work yet to be performed in connection with the Sunrise Provision in our Post-Adoption Plan. This will not be a definitive document but will serve as one perspective on potential sites. We are highly concerned that the Town will lose valuable time if we don’t act quickly to support our outreach efforts in this way. We view this as a necessary and valuable step in our process, which does not obligate the Town to undertake a particular path.

Action Item. Accordingly, we request that the Town Council direct the Town Manager to enter into an agreement with Serra to conduct an initial assessment of up to six types of sites for up to a total of $25,000. The work product from this assessment would inform our subcommittee’s work and serve as one source among several for developing a strategy for implementing our Housing Element commitments.

We attach an outline of the proposal for the conduct of such an initial assessment here as Attachment 1.

Outline Proposal to Town of Portola Valley
Goal. The goal is to assess the potential sites and select a probable site to fulfill a portion of the State’s VLI, ELI, and LI allocation. This initial phase would provide (a) a high-level review of the zoning, physical capacity, and feasibility of six sites (to be agreed prior to project start) as well as (b) in depth review of one site to be agreed after completion of Step 1. Step 1 could consider sites with existing facilities. Step 1 could consider Ford Park or certain vacant sites.

Service Provider: Keystone Development Group (Serra Real Estate Capital would be subcontractor) Client: Town of Portola Valley or affiliate
Timeline for Completion: 60 days (approximately)
Terms: $25,000; 50% up front; 50% on completion

Step 1 - High-level assessment and evaluation of approximately six potential mixed-income affordable housing sites. a. Physical site visit.
b. Review of zoning and approval requirements.
c. Conceptual product size considerations.
d. High-level assessment of pros and cons.

Step 2 - Selection of one site for a deeper analysis, summary to include:

1. Architect’s conceptual site assessment and one or two site plan layouts to show sample project size (number of units) and product mix (bedroom mix).

2. Experienced contractor to provide construction cost estimates based on likely type of construction.

3. Project capital cost budget (including project costs beyond construction).

4. Preparation of high-level financial analysis:
a. Using proposed project size, unit mix, and affordability mix (AMI income levels). b. Including evaluation of multiple funding scenarios including Credit Tenant Lease (CTL’s), Federal and State tax credits, State affordable housing programs, Federal housing programs, B-bonds, and traditional debt.

5. Assessment of benefits, risk, and other considerations, including potential timelines, restrictions that come with accepting specific funding, and other issues.

Means. Would engage and oversee an architect, contractor, and financial consultant as needed to achieve the scope.

Work Product: Work product would be two-fold:

For Step 1: 2 - 3-page written summary, incorporating findings and recommending which site[s] could be best suited for Step 2.

For Step 2: 10–15-page Executive Summary (with exhibits) incorporating site plan, likely type of construction needed and why, development budget, sources and uses, projected rents, operating budget, list of pro’s and con’s; review of applied projected financing alternatives; and estimated development timeline.

RE: Introduction Ordinances Amending Title 18 [Zoning] of the Portola Valley Municipal Code and Amending the Zoning Map for the Town of Portola Valley to Implement the 2023-2031 Housing Element (Continued Public Hearing from May 22, 2024)

RECOMMENDATION
Staff recommends that the Town Council introduce and waive the first reading Ordinances Amending Title 18 [Zoning] of the Portola Valley Municipal Code and Amending the Zoning Map for the Town of Portola Valley to Implement the 2023-2031 Housing Element (Attachment 1 and 2).

BACKGROUND
For background on the Portola Valley Housing Element adoption and certification, necessity of timely adoption of Zoning Code and Zoning Map amendments, applicable SB330 legislation and other applicable information, please view the May 22, 2024 Town Council agenda packet. For more information on the seven combined ASCC and Planning Commission meetings to review and provide recommended amendments to the draft Zoning Code and Zoning Map amendments, view the May 8, 2024 Planning Commission meeting packet.

At its May 22, 2024 meeting, the Town Council first considered the draft Zoning Code and Zoning Map amendments. In its presentation, staff recommended that Council consider incorporating several additional amendments to the draft to address issues of clarity and consistency. These amendments did not add any substantive new information that would otherwise impact the previous analyses conducted by the ASCC and Planning Commission that informed their prior recommended amendments. Council directed staff to make three grammatical revisions and to reconcile confusion in the term “fronting” as it relates to the story maximum for future units located adjacent to Nathhorst Avenue on the

TOWN OF PORTOLA VALLEY

STAFF REPORT

Page 13 of 148 ends

4370 Alpine Road housing site. Council also expressed its support for timely development of the Ladera Church housing site and its wishes that the Town find a way to make clear that it will support the Church’s affordable housing endeavors and provide them with the technical assistance they require. For further detail and proposed revisions to the draft Zoning Code to address the foregoing matters raised by Council, see the Discussion section below.

Council also supported the Planning Commission’s intention to author a Colleague’s Memo to be written by Chair Goulden and Vice Chair Targ and provided to the Council.

The intent of the memo is to identify several important areas it recommends Council prioritize. These items are beyond the immediate scope of amendments required to implement the Housing Element but are nonetheless considered pressing in the near to mid-term. The memo will capture matters ranging from a comprehensive clean up of the Zoning Code to rectify naming conventions, clarity of language etc., to proposing further simplified ministerial path for small, affordable housing projects. Council directed staff to convey its enthusiasm Planning Commission/ASCC Subcommittee and its wish to receive the memo promptly.

DISCUSSION
Additional Proposed Amendments to Draft
All text revisions to the draft code may be viewed in Attachment 3. Original amendments as recommended by the Planning Commission appear in BLUE, while the Council’s requested amendments appear in RED. A brief explanation of all amendments follows:

1. Figure 18.15.060.B.1: Building Articulation, Façades over 65 Feet – A grammatical error in the notation of the figure is corrected to “change”

2. 18.29.060 Required conditions—development standards (A) (1) Sequoias: Up to and including 23 units, as described in the Housing Element. (2) Christ Church: Up to and including 6 units, as described in the Housing Element.

18.29.060 Required conditions—development standards (C)(1) For sites with a density of up to and including 6 du/ac…

3. 18.60.030 Location and type - (A) In residential districts, required parking facilities, except required guest parking spaces, shall be in a carport or garage and all spaces shall be located on the same parcel or building site as the buildings they are required to serve unless otherwise authorized by conditional use permit, or otherwise regulated by the Opt-in Housing Diversification Program established by the Portola Valley Housing Element.

Staff worked with a neighborhood representative to address confusion over the term “fronting” stated in Note 3 in Table 18.23.050: Development Standards – Mixed-Use District.

Page 14 of 148 ends

4. Previous language:

Units on 4370 Alpine Road fronting Nathhorst Avenue shall be limited to one story.

Proposed revised language: Building height on 4370 Alpine Road is limited to one story within 50 feet of the property line along Nathhorst Avenue.

Staff also made several recommended amendments in its meeting presentation to Town Council:

1. Table 18.23.050: Development Standards – Mixed-Use District - current maximum Coverage Area Ratio (CAR) 0.20 needs to match maximum Floor Area Ratio (FAR) (0.22). This is a technical correction for internal consistency

2. For MF-23 projects, allow for all required parking to be surface and eliminate requirement for resident parking in garages/carports. Proposed revision to Chapter

18.60.030 Off-Street Parking (A):

In residential districts, required parking facilities, except required guest parking spaces, shall be in a carport or garage and all spaces shall be located on the same parcel or building site as the buildings they are required to serve unless otherwise authorized by conditional use permit, otherwise regulated by the Opt-in Housing Diversification Program established by the Portola Valley Housing Element. This requirement does not apply to the MF-23 zoning district.

3. Staff is proposing a small addition to the new R-MF (MULTI-FAMILY RESIDENTIAL) chapter, which is to add language specifically noting that any projects proposing development with a minimum density of 20 units per acre and with at least 20% of the units dedicated to lower income households shall be permitted by right. This is a requirement of Government Code section 65583.2, subdivisions (h) and (i)), and is identified in Programs 1-1a, 1-1b, and 1-6 in Portola Valley’s Housing Element. It has recently come to staff’s attention that HCD wants to see this language explicitly stated in the zoning code sections that implement multifamily zoning, so this addition is proposed to be included as new Section

18.23.025.

18.15.025 Uses Allowed by Right
In accordance with Housing Element law (Government Code section 65583.2, subdivisions (h) and (i)), housing developments with a minimum density of 20 units per acre in which 20 percent or more of the units are affordable to lower income households shall be permitted by-right (without discretionary action). In compliance with Section 18.64.090 (Action by architectural and site control commission), the ASCC will review the proposed project for consistency with the objective standards contained in this chapter.

Page 15 of 148 ends

4. A change to the CHAPTER 18.04 DEFINITIONS is intended to provide clarity for housing sites with identified site constraints. The proposed change clarifies that in the MU and MF zones, density is calculated based on “developable area”, which is the portion of the full parcel area net of site constraints.

18.04.115 Density. “Density” means the ratio between dwelling units and land, expressed as the number of dwelling units per gross acre (du/ac). For the MU (Mixed Use) and MF (Multi-Family) Districts, density means the ratio between dwelling units and a site’s developable area, expressed as the number of dwelling units per net acre.

18.04.256 Net acre. “Net acre” is the gross acreage minus areas not available for development, such as: conservation easements, access easements, seismic setbacks, riparian setbacks, sensitive habitats or other similar constraints.

Formatting of Zoning Ordinance
Staff has reformatted the zoning ordinance amendments into two separate ordinances.

The first ordinance addresses the MU (Mixed Use) zone only. The second ordinance addresses R-MF (Multi-Family Residential) and all other aspects of the zoning amendments. The formatting change allows for a segmented vote on the two ordinances and enables Council members with conflicts of interest regarding the MU zone to recuse on that portion.

ENVIRONMENTAL ANALYSIS
On March 29, 2023, the Town Council adopted, pursuant to the California Environmental Quality Act (CEQA), an Initial Study-Mitigated Negative Declaration (ISMND) prepared for the Portola Valley Housing and Safety Elements Update and Conforming General Plan and Zoning Code Amendments. Prior to Town Council’s January 24, 2024, adoption of the Housing Element, the IS-MND was again reviewed to determine if revisions to the Housing Element occurring after the adoption of the ISMND would require modifications to the document. It was concluded at that time that all mitigation measures in the IS-MND remained valid and reduced all project-related impacts to a less-than-significant level. Likewise, staff has reviewed the implementing Zoning Code text amendments and amendments to the Zoning Map and concluded that they do not require subsequent or supplemental environmental analysis under CEQA, and further concluded that the IS/MND adopted on March 29, 2023, remains valid.

NEXT STEPS
Town Council will next meet at a regular meeting on June 12, 2024 for a second reading of an Ordinance Amending Title 18 [Zoning] of the Portola Valley Municipal

Page 16 of 148 ends

Code and Amending the Zoning Map. Once Town Council has completed its adoption of the ordinance, staff will submit to HCD the amended Zoning Code with the expectation that it will again find the Town’s Housing Element in substantial compliance with State Law.

Public Comment
At the time of writing this report, no public comments were received. As applicable, any additional comments received up to 1:00pm on May 29, 2024 will be posted to the meeting calendar page.

FISCAL IMPACT
There is no fiscal impact in accepting this report and update. The contract amount for the Consultants engaged to assist with the preparation of the Zoning Code and Zoning Map amendments is $192,243 – of which approximately $130,950 has been exhausted.

Expenditures of time spent by town staff, town attorney and other town resources on the progress of this project to date are undetermined.

TABLE 4—PARKING LOT DIMENSIONS
Width of stall…..9'
Length ofstall…..18'*
Width of aisle…..25'
*Up to two feet of overhang may be deducted from required stall length if the overhang does not interfere with planting, walks or other site features and is approved by the architectural and site control commission.

The foregoing standards are for ninety-degree parking and an aisle for two-way traffic. Parking at other angles shall provide for similar geometric standards as approved by the town engineer. (Ord. 1987-223 § 1, 1987; Ord. 1979-166 § 16 (part), 1979; Ord. 1967-80 § 1 (6210.1 (A)), 1967)

18.60.030 Location and type.

Off-street parking facilities shall be located as specified in this section. Where a distance is specified, the distance shall be the walking distance measured from the nearest point of the parking facility to the nearest entrance of the building that the facility is required to serve.

A. In residential districts, required parking facilities, except required guest parking spaces, shall be in a carport or garage and all spaces shall be located on the same parcel or building site as the buildings they are required to serve unless otherwise authorized by conditional use permit, or otherwise regulated by the Opt-in Housing Diversification Program established by the Portola Valley Housing Element. This requirement does not apply to the R-MF-23 zoning district.

B. For uses in other districts, parking spaces may be located on separate sites provided they are not over two hundred fifty feet from the buildings they are required to serve.

C. When the required off-street parking facilities are not situated on the same parcel as the use they are required to serve, there shall be recorded a covenant as required for joint use under paragraph D (3) of Section 18.60.070.

Page 78 of 148 ends

D. In R-1/7.5M, 15M and 20M zoning districts, where the ASCC finds there is no reasonable location for a second required covered parking space that would have direct unobstructed vehicular access, such required parking space may be uncovered and/or in tandem, provided that in the case of an uncovered space, two hundred square feet shall be considered as floor area for purposes of determining compliance with the floor area limitations on a parcel. On parcels of twenty thousand square feet or less, an uncovered parking space may occupy required yard areas upon approval by the ASCC and after notification to affected neighbors. (Ord. 1967-80 § 1 (6210.1 (B)), 1967; Ord. 2001-338 § 7 (part), 2001)

18.60.040 Determination of parking facility requirements—Units of measurement.

A. For the purpose of this section, "floor area" shall mean the gross floor area in the building other than floor space designated and used exclusively for parking and loading spaces, building service and maintenance, or storage of equipment and furnishings belonging to the occupants of the building but not in current use.

B. In indoor or outdoor places of assembly in which patrons or spectators occupy benches, pews, or other similar seating facilities, each twenty inches of such seating facility shall be counted as one seat for the purpose of determining requirements for off-street parking facilities.

BC. When units of measurements determining number of required parking spaces result in requirement of a fractional space, any fraction up to and including one-half shall be disregarded and fractions over one-half shall require one parking space.
(Ord. 1967-80 § 1 (6210.1 (C)), 1967)

18.60.050 Determination of parking facility requirements—Changes in use—Additions and enlargement.

Whenever on any parcel there is a change in use, or increase in floor area, or in the number of employees or other unit of measurement specified in this chapter to indicate the number of required off-street parking spaces and such change or increase creates a need for an increase of more than ten percent in the number of off-street parking spaces, as determined by the tables in this chapter, additional off-street parking spaces shall be provided on the basis of the increased requirements of the new use, or on the basis of the total increase in floor area, or in the number of employees, or in other unit of measurement. The effects of additions, enlargements, and changes in use subsequent to July 18, 1967, shall be cumulative in regard to off-street parking requirements. (Ord. 1967-80 § 1 (6210.1 (D)), 1967)

18.60.060 Determination of parking facility requirements—Mixed occupancies and uses not specified.

In the case of a use not specifically mentioned in Section 18.60.110, the requirements for off-street parking facilities for a use which is so mentioned and to which the use is similar, shall apply as determined by the planning commission. In the case of mixed uses, the total requirements for off-street parking facilities shall be the sum of the requirements for the various uses computed separately. Off-street parking facilities for one use shall not be considered as providing required parking facilities for any other use except as specified in Section 18.60.070 for joint use.

The covenant required in this paragraph shall stipulate that the title to and right to use the parcel or parcels upon which the parking space is to be provided will be subservient to the title to the premises upon which the building is to be erected, and that it is warranted that the parcel or parcels are not and will not be made subject to any other covenant or contract for use without prior written consent of the town. (Ord. 1967-80 § 1 (6210.1 (F)), 1967)

18.60.080 Common facilities.

Common parking facilities may be provided in lieu of the individual requirements contained in this chapter, but such facilities shall be approved by the planning commission as to size, shape, and relationship to sites to be served, provided the total of such off-street parking spaces, when used together, shall not be less than the sum of the various uses computed separately, taking into consideration allowable reductions for joint use as set forth in Section 18.60.070. When any such common facility is to occupy a site of five thousand square feet or more, then the parking requirements as specified in this chapter for each of two or more participating buildings or uses may be reduced not more than fifteen percent upon approval of development plans by the planning commission in the manner prescribed for a conditional use permit as set forth in Chapter 18.72, provided such area saved be preserved as open space in addition to other open spaces required by this title. In any case, where common parking facilities are to be provided, there shall be a covenant recorded in a form first approved by the town covering the matters set forth under paragraph D (3) of Section 18.60.070.
