ADMINISTRATIVE REPORT
MEETING DATE: February 26, 2025 AGENDA CATEGORY: Public Safety Vital Services TO: Honorable Mayor and City Council
FROM: Jennifer M. Byers, Economic and Community Development Director DATE: January 22, 2025
SUBJECT: Transfer ($8,000,000) of Public Safety and Vital Services Affordable Housing Funds from the Public Safety and Vital Services Economic and Community Development Capital Improvement Budget to the Affordable Housing Trust Fund.
RECOMMENDATION:
Staff recommends approval of transfer.
BACKGROUND:
On July 14, 2021, the City Council approved Resolution 124-2021, establishing the Bakersfield Affordable Housing Trust Fund (AHTF) to assist in the development of affordable housing to meet the housing needs of the City’s very low-, low- and moderate-income households. The creation of this fund is a general benefit to the city that promotes the health and welfare of the residents and businesses improving housing opportunities and reducing homelessness within the city.
It was the intent of the City Council that the AHTF would be funded by Public Safety Vital Services (PSVS) Measure N funds to match or leverage other public or private sources. The AHTF is utilized to foster a mix of residential projects assisted by the AHTF and to disperse affordable housing projects throughout the city to achieve a balance of housing in all neighborhoods and communities.
To continue required grant matches and leveraging, Economic and Community Development requests to transfer $5,000,000 of fiscal year 2023-2024 and $3,000,000 of fiscal year 2024-2025 budgeted PSVS affordable housing funds to the AHTF.
FISCAL IMPACT:

ADMINISTRATIVE REPORT
MEETING DATE: February 26, 2025 AGENDA CATEGORY: Hearings TO: Honorable Mayor and City Council
FROM: Zachary Meyer, Public Works Director
DATE: February 14, 2025
SUBJECT: Appeal Hearing to consider Traffic Impact Fees imposed on Planet Fitness, located at 11425 Stockdale Highway
at “The Village @ River Oaks” (Ward 5)
RECOMMENDATION:
Staff recommends City Council deny the appeal and uphold the Traffic Impact Fee imposed on Appellant.
BACKGROUND:
In 2018, Planning Commission approved a proposed Planned Development Review (18-0385) for a 73,800 Sq. ft. mixed-used shopping center at the SWC of Buena Vista Road and Stockdale Hwy. The initial Traffic Impact Fees for the shopping center were calculated based on an Average Daily Trip (ADT) of 79 trips/1000 sq.ft., based on Institute of Transportation Engineering (ITE 8th Edition), and a trip rate ($167) per Resolution 084-09. The Appellant’s engineer also prepared trip generation calculations, determining an Average Daily Trip rate of 75.5 trips per 1,000 square feet for the shopping center. This rate was then used to calculate the final Traffic Impact Fees assessed to the shopping center.
On January 19, 2023, Planning Commission approved a revised Planned Development Review (22-0111) to include a Fitness Center, Car Wash and an additional Restaurant. A new traffic calculation was provided by Appellant’s engineer, showing an ADT of 80.72 trips per 1,000 Sq. ft. Traffic Impact fees for Planet Fitness and Car Wash were calculated based on the updated ADTs, resulting in a fee of $340,470.42 for Planet Fitness (Appellant).
The Appellant requested City use the current ITE 11th edition, as previous ITE editions didn’t provide data for shopping centers without a supermarket. Public Works Director approved the request to use 11th edition. Revised Traffic calculations were prepared by Appellant’s engineer for a shopping center with no supermarket. New Traffic calculations resulted in a lower ADT of 67.52 trips per 1000 sq.ft. ADT reduced to 67.52 resulting in a lower Traffic Impact fee to $284,793.89.
Despite the fee reduction, Appellant does not agree with the revised Traffic Impact Fees for the proposed Planet Fitness and requested it be treated as a standalone building. Public Works Director denied said request since Appellant is not a standalone building and is clearly part of a commercial shopping center (i.e. multiple uses, shared points of entry, shared utility access, shared common uses, etc.).
FISCAL IMPACT:
The traffic Impact Fees collected will pay for the construction of both regional and local infrastructure facilities that are required to maintain Level of Service C for the Metropolitan transportation system. The proposed reduction in fees collected by the Appellant will not allow the City to invest what is required to keep our roads safe.
COUNCIL GOAL:
Reliable Infrastructure.

ADMINISTRATIVE REPORT
MEETING DATE: February 26, 2025 AGENDA CATEGORY: Deferred Business TO: Honorable Mayor and City Council
FROM: Jennifer M. Byers, Economic and Community Development Director DATE: February 10, 2025
SUBJECT: Continued Discussion Regarding Amendment No. 3 to Agreement No. 2020-255 for the Hope to Home Down Payment Assistance Program
Amendment No. 3 to Agreement No. 2020-255 with Ventura County Community Development Corporation (VCCDC) (increase maximum purchase price to limits provided by HUD; increase grant funding to $770,000; and extend term to March 1, 2027) for continued operation of the Hope to Home Down Payment Assistance Program.
RECOMMENDATION:
Staff recommends approval of the amendment.
BACKGROUND:
On January 8, 2025, staff proposed Amendment No. 3 to Agreement No. 2020-255 to extend the term of the Agreement to March 1, 2027, increase the amount of grant funding to $770,000 to provide down payment assistance to 18 eligible households, and increase the maximum purchase price to $385,700 per home. Councilmember Bob Smith made a motion to continue the item for further discussion to evaluate the rising limit of the maximum purchase price, and Council voted to defer until a future meeting date.
Staff has reviewed Council’s referral and relevant Department of Housing and Urban Development (HUD) guidelines. According to HOME regulation 24 CFR 92.254(a)(2)(iii), if a participating jurisdiction intends to use HOME funds for homebuyer assistance, the jurisdiction must annually review the HUD affordable homeownership limits. HUD provides two options to determine maximum sales price:
Option 1: Utilize HUD-published limits for HOME Homeownership Value Limits as determined for the Kern County, Bakersfield Metropolitan Statistical Area; or Option 2: The participating jurisdiction may determine 95% of the median purchase price for the area as set forth in 24 CFR 92.254(a)(iii)(A-E).
Historically, the City utilized the sales price limits imposed by HUD (Option 1); however, in 2023 the HUD limit did not adequately reflect the local market with very few homes in that sales price range. As a result, Amendment No. 1 to Agreement No. 2020-255 set the limit based on 95% of the median purchase price for the area (Option 2). Staff evaluated both options and determined that the current HUD limit is $371,000, and the formula option is $385,700.
City staff propose utilizing Option 1, with a maximum purchase price of $371,000, as there are approximately 800 homes currently for sale in the Bakersfield area within that range. With this amendment, staff will revise the Action Plan for Fiscal Year 2024-2025 of the Consolidated Plan, using the most recent HUD-published limit for Kern County as the maximum purchase price for the VCCDC program.
Staff recommends council approve Amendment No. 3 to Agreement No. 2020-255, to extend the term of the Agreement to March 1, 2027, increase the amount of grant to $770,000 to provide down payment assistance to at least 18 eligible households, and increase the maximum purchase price to the most recent HUD-published limit.
FISCAL IMPACT:
Funds were budgeted as part of the FY 24-25 HUD Action Plan and will result in no impact to the general fund.
COUNCIL GOAL:
Safety and Resilience
