16.45.055 Master planned projects.

The purpose of a master planned project is to provide flexibility for creative design, more orderly development, and optimal use of open space, while maintaining and achieving the general plan vision for the Bayfront Area. Master planned projects for sites with the same zoning designation (O, LS, or R-MU) in close proximity or for contiguous sites that have a mix of zoning designations (O or R-MU) that exceed fifteen (15) acres in size and that are held in common ownership (or held by wholly owned affiliated entities) and are proposed for development as a single project or single phased development project are permitted as a conditional use; provided, that sites with mixed zoning are required to obtain a conditional development permit and enter into a development agreement. For master planned projects meeting these criteria, residential density, FAR and open space requirements and residential density, FAR, and open space requirements at the bonus level, if applicable, may be calculated in the aggregate across the site provided the overall development proposed does not exceed what would be permitted if the site were developed in accordance with the zoning designation applicable to each portion of the site and the proposed project complies with all other design standards identified for the applicable zoning districts. (Ord. 1026 § 3 (part), 2016).

16.45.060 Bonus level development.

As described in Section 16.45.070, as a threshold requirement for utilizing bonus level development in the residential mixed use-bonus (R-MU-B) zoning district, the applicant must construct the below market rate units required pursuant to Chapter 16.96 on site rather than utilizing an alternative means of compliance per Section 16.96.070, unless otherwise approved by the city council. Any such units will be sold or rented with a preference for current or recently displaced Belle Haven residents, followed by the preferences provided in the city’s below market rate housing guidelines. If and when Chapter 16.96 becomes void or unenforceable, the community amenity provided must be a minimum of fifteen percent (15%) of the total units on site for affordable housing units in accordance with the city’s below market rate housing ordinance and guidelines. (Ord. 1047 § 2, 2018: Ord. 1026 § 3 (part), 2016).

16.45.070 Community amenities required for bonus level development.

Bonus level development allows a project to develop at a greater level of intensity with an increase in density, floor area ratio and/or height. There is a reasonable relationship between the increased intensity of development and the increased effects on the surrounding community. The required community amenities are intended to address identified community needs that result from the effect of the increased development intensity on the surrounding community. To be eligible for bonus level development, an applicant shall provide one (1) or more community amenities. Construction of the amenity is preferable to the payment of a fee.

(1) Amenities. Community needs, specifically including affordable housing, were initially identified through the robust community engagement process generally referred to as ConnectMenlo. The city council of the city of Menlo Park adopted by resolution those identified community needs as community amenities to be provided in exchange for bonus level development. The identified community amenities may be updated from time to time by city council resolution. All community amenities, except for affordable housing, shall be provided within the area between U.S. Highway 101 and the San Francisco Bay in the city of Menlo Park. Affordable housing may be located anywhere housing is allowed in the city of Menlo Park.

(2) Application. An application for bonus level development is voluntary. In exchange for the voluntary provision of community amenities, an applicant is receiving a benefit in the form of an increased floor area ratio, density, and/or increased height. An applicant requesting bonus level development shall provide the city with a written proposal, which includes but is not limited to the specific amount of bonus development sought, the value of the amenity as calculated pursuant to subsection (3) of this section, and adequate information identifying the value of the proposed community amenities. An applicant’s proposal for community amenities shall be subject to review by the planning commission in conjunction with a use permit or conditional development permit. Consideration by the planning commission shall include differentiation between amenities proposed to be provided on site and amenities proposed to be provided off site, which may require a separate discretionary review and environmental review per the California Environmental Quality Act.

(3) Value of Amenity. The value of the community amenities to be provided shall equal fifty percent (50%) of the fair market value of the additional gross floor area of the bonus level development. The value shall be calculated as follows: The applicant shall provide, at their expense, an appraisal ("applicant’s appraisal") on or after the application date by a licensed appraisal firm that sets a fair market value in cash of the gross floor area of the bonus level of development ("bonus value"). The bonus value shall be determined without consideration of the community amenities requirement established under this section. The applicant’s appraisal shall be based on a date of value that is within ninety (90) days of the date of the applicant’s appraisal, but in no event shall the date of value be earlier than the application date. The form and content of the applicant’s appraisal must be approved by the community development director. The city council shall adopt regulations providing for a process by which the community development director shall determine a final appraised value. The final appraised value shall be based on the same date of value as the applicant’s appraisal and shall constitute the city’s final determination of the bonus value. Fifty percent (50%) of the total bonus value is the value of the community amenity to be provided.

(4) Form of Amenity. A community amenity shall be provided utilizing any combination of the following mechanisms:

(A) Include the community amenity as part of the project. As a threshold for utilizing bonus level development, any affordable housing required pursuant to Chapter 16.96 shall be designed and constructed on site as part of the project; the applicant shall not be allowed to utilize an alternative means of compliance, unless otherwise approved by the city council. These affordable housing units shall be sold or rented with a preference for current or recently displaced Belle Haven residents, followed by the preferences provided in the city’s below market rate housing guidelines. The community amenity provided as part of the project shall be from the list of community amenities adopted by city council resolution, with a preference for including additional affordable housing units; for example, additional housing such that twenty percent (20%) of the development is affordable (fifteen percent (15%) inclusionary plus five percent (5%) additional affordable units). The value of the community amenity provided shall be at least equivalent to the value calculated pursuant to the formula identified in subsection (3) of this section. Once any one (1) of the community amenities on the list adopted by city council resolution has been provided, with the exception of affordable housing, it will no longer be an option available to other applicants. Prior to approval of final inspection for the building permit for any portion of the project, the applicant shall complete (or bond for) the construction and installation of the community amenities included in the project and shall provide documentation sufficient for the city manager or their designee to certify compliance with this section.

(B) In-Lieu Payment. An applicant for bonus development may elect to pay one hundred ten percent (110%) of the value of the community amenity to be provided, as calculated pursuant to subsection (3) of this section. An in-lieu payment may be made in combination with the provision of a community amenity as a part of the project, as long as the in-lieu payment portion is equal to one hundred ten percent (110%) of the value of the community amenity to be provided, minus the value of the community amenity provided as calculated pursuant to subsection (3) of this section. The applicant shall provide documentation sufficient for the city manager or their designee to certify compliance with this section. In-lieu payments shall be made prior to building permit issuance for the project. The city shall place all in-lieu payments in a restricted community amenities fund to be used to implement community amenities identified in the list adopted by city council resolution.

(C) Enter into a development agreement. An applicant may implement community amenities that are not on the list of community amenities adopted by city council resolution, by entering into a development agreement for the bonus level project and the community amenities, pursuant to Article 2.5 of Chapter 4 of Division 1 of Title 7 (Section 65864 et seq.) of the California Government Code and any city ordinances, resolutions, and procedures governing development agreements. (Ord. 1100 § 4, 2023; Ord. 1077 § 4, 2021; Ord. 1047 § 3, 2018: Ord. 1026 § 3 (part), 2016).

1 See Section 16.45.120(7) and the latest edition of best practice design standards in Association of Pedestrian and Bicycle Professionals Bicycle Parking Guidelines.

2 Long-term parking is for use over several hours or overnight, typically used by employees and residents. Short-term parking is considered visitor parking for use from several minutes to up to a couple of hours.

(1) Parking spaces shall be unbundled from the price of residential units such that parking is sold or rented separately, except in cases where parking is physically connected to only one (1) unit. However, the planning commission may grant an exception from this requirement for projects which include financing for affordable housing that requires that costs for parking and housing be bundled together.

(2) Parking facilities may be shared at the discretion of the city’s transportation manager if multiple uses cooperatively establish and operate the facilities, if these uses generate parking demands primarily during different hours than the remaining uses, and if a sufficient number of spaces are provided to meet the maximum cumulative parking demand of the participating uses at any time. An individual development proposal may incorporate a shared parking study to account for the mixture of uses, either on site or within a reasonable distance. The shared parking supply would be subject to review and approval based on the proposed uses, specific design and site conditions. Project applicants may also be allowed to meet the minimum parking requirements through the use of nearby off-site facilities at the discretion of the transportation manager. (Ord. 1026 § 3 (part), 2016).

16.45.090 Transportation demand management.

All new construction, regardless of size, and building additions of ten thousand (10,000) or more square feet of gross floor area, or a change of use of ten thousand (10,000) or more square feet of gross floor area shall develop a transportation demand management (TDM) plan necessary to reduce associated vehicle trips to at least twenty percent (20%) below standard generation rates for uses on the project site. Each individual applicant will prepare its own TDM plan and provide an analysis to the satisfaction of the city’s transportation manager of the impact of that TDM program.

(1) Eligible TDM measures may include but are not limited to:

(A) Participation in a local transportation management association (TMA) that provides documented, ongoing support for alternative commute programs;

(A) Documented in a TDM plan developed specifically for each project and noted on project site plans, if and as appropriate;

(B) Guaranteed to achieve the intended reduction over the life of the development, as evidenced by annual reporting provided to the satisfaction of city’s transportation manager;

(C) Required to be replaced by appropriate substitute measures if unable to achieve intended trip reduction in any reporting year;

(D) Administered by a representative whose updated contact information is provided to the transportation manager. (Ord. 1026 § 3 (part), 2016).

16.45.100 New connections.

Proposed development will be required to provide new pedestrian, bicycle, and/or vehicle connections to support connectivity and circulation as denoted in the city zoning map. These connections may be in the form of either a public street or a paseo as denoted in the city zoning map and are pursuant to the standards in Section 16.45.120. Streets shall meet the requirements of the adopted city of Menlo Park street classification map in the general plan circulation element.

(1) If the location of a new connection is split between parcel/ownership, the first applicant must set aside the required right-of-way through dedication or a public access easement and bond for the completion of the new connection, or reach agreement with the other property owner(s) to allow the first applicant to complete the entire new connection;

(2) If the location of a new connection is located on multiple properties with the same owner, applicant may move the connection up to fifty (50) feet in either direction from what is shown on the city zoning map for enhanced connectivity, and/or other considerations, subject to the review and approval of the city’s public works director;

(3) For phased implementation of a development project, applicant must show an implementation plan for the new connection and the city may require a bond or right-of-way dedication or public access easement prior to the completion of the first phase;

(4) The land area dedicated for new connections in the form of public streets (right-of-way) will be subtracted from the total lot area to determine the site’s floor area ratio;

(5) The land area dedicated for new connections in the form of paseos will require a public access easement (PAE). The area of the PAE is included in the total lot area to determine the site’s floor area ratio. (Ord. 1026 § 3 (part), 2016).

16.45.110 Required street improvements.

For new construction and/or building additions of ten thousand (10,000) or more square feet of gross floor area or for tenant improvements on a site where the cumulative construction value exceeds five hundred thousand dollars ($500,000) over a five (5) year period, the public works director shall require the project to provide street improvements on public street edges of the property that comply with adopted city of Menlo Park street construction requirements for the adjacent street type. When these are required by the public works director, the improvements do not count as community amenities pursuant to Section 16.45.070. The threshold for the value of improvements shall be adjusted annually on the first day of July, based on the ENR Construction Cost Index.

(1) Improvements shall include curb, gutter, sidewalk, street trees, and street lights;

(2) Overhead electric distribution lines of less than sixty (60) kilovolts and communication lines shall be placed underground along the property frontage;

(3) The public works director may allow a deferred frontage improvement agreement, including a bond to cover the full cost of the improvements and installation to accomplish needed improvements in coordination with other street improvements at a later date. (Ord. 1026 § 3 (part), 2016).

16.45.120 Design standards.

All new construction, regardless of size, and building additions of ten thousand (10,000) square feet or more of gross floor area adhere to the following design standards, subject to architectural control established in Section 16.68.020. For building additions, the applicable design standards apply only to the new construction. The existing building and new addition shall have an integrated design. Design standards may be modified subject to approval of a use permit or a conditional development permit per Chapter 16.82.

1 "Designed to meet LEED standards" is defined as follows: (a) applicant must submit appropriate LEED checklist and verifying cover letter from a project LEED AP with the project application and (b) applicant must complete all applicable LEED certification documents prior to approval of the final inspection for the building permit to be reviewed either for LEED certification, or for verification by a third party approved by the city for which the applicant will pay for review and/or certification.

2 Building owners may choose to have additions and/or alterations follow the LEED ID+C path, or alternatively, building owners may upgrade the entire existing building’s core and shell to the current California Energy Code standards and follow the city’s requirements listed in Section 16.45.130(2)(B). If the building owner chooses to upgrade the entire building’s core and shell to current California Energy Code standards and follow the city’s requirements listed in Section 16.45.130(2)(B), additions and alterations of that building will be exempt from the LEED ID+C requirement for three (3) code update cycles beginning with the upgrade cycle and ending with the two (2) cycles following the upgrade cycle. If this option is selected by the applicant, the building owner must upgrade to the Energy Code in effect at the time of the first building permit application for interior alteration and/or additions. Building permits for the core and shell upgrade must be initiated and satisfactory progress must be made on the core and shell upgrade project before occupancy for the additions and/or alterations shall be granted by the city’s building department. If the building owner fails to complete these core and shell upgrades within one (1) year of permit initiation, or receive a written letter from the community development director or his/her designee extending the deadline, the building owner shall be subject to typical permit violation penalties, including but not limited to stop work orders on any construction on the subject property, fines, and legal action.

3 If over a period of five (5) years (or sixty (60) months) the subject property makes smaller additions and/or alterations that cumulatively equal or exceed the trigger square footage listed above (i.e., ten thousand (10,000) square feet or twenty-five thousand one (25,001) square feet), the subject property shall be required to comply with the green and sustainable building requirements of this table.

(3) Water Use Efficiency and Recycled Water.

(A) Single pass cooling systems shall be prohibited in all new buildings.

(B) All new buildings shall be built and maintained without the use of well water.

(C) Applicants for a new building more than one hundred thousand (100,000) square feet or more of gross floor area shall prepare and submit a proposed water budget and accompanying calculations following the methodology approved by the city. For all new buildings two hundred fifty thousand (250,000) square feet or more in gross floor area, the water budget shall account for the potable water demand reduction resulting from the use of an alternative water source for all city approved nonpotable applications. The water budget and calculations shall be reviewed and approved by the city’s public works director prior to certification of occupancy. Twelve (12) months after the date of the certification of occupancy, the building owner shall submit data and information sufficient to allow the city to compare the actual water use to the allocation in the approved water budget. In the event that actual water consumption exceeds the water budget, a water conservation program, as approved by the city’s public works director, shall be implemented. Twelve (12) months after city approval of the water conservation program, the building owner shall submit data and information sufficient to allow the city to determine compliance with the conservation program. If water consumption exceeds the budgeted amount, the city’s public works director may prohibit the use of water for irrigation or enforce compliance as an infraction pursuant to Chapter 1.12 until compliance with the water budget is achieved.

(D) All new buildings shall be dual plumbed for the internal use of recycled water.

(E) All new buildings two hundred fifty thousand (250,000) square feet or more in gross floor area shall use an alternate water source for all city approved nonpotable applications. An alternative water source may include, but is not limited to, treated nonpotable water such as graywater. An alternate water source assessment shall be submitted that describes the alternative water source and proposed nonpotable application. Approval of the alternate water source assessment, the alternative water source and its proposed uses shall be approved by the city’s public works director and community development director. If the Menlo Park Municipal Water District has not designated a recycled water purveyor and/or municipal recycled water source is not available prior to planning project approval, applicants may propose conservation measures to meet the requirements of this section subject to approval of the city council. The conservation measures shall achieve a reduction in potable water use equivalent to the projected demand of city approved nonpotable applications, but in no case shall the reduction be less than thirty percent (30%) compared to the water budget in subsection (3)(C) of this section. The conservation measures may include on-site measures, off-site measures or a combination thereof.

(F) Potable water shall not be used for dust control on construction projects.

(G) Potable water shall not be used for decorative features, unless the water recirculates.

(4) Hazard mitigation and sea level rise resiliency.

(A) The first floor elevation of all new buildings shall be twenty-four (24) inches above the Federal Emergency Management Agency base flood elevation (BFE) to account for sea level rise. Where no BFE exists, the first floor (bottom of floor beams) elevation shall be twenty-four (24) inches above the existing grade. Notwithstanding the foregoing, for projects on sites of two (2) acres or less, the first floor elevation shall be the maximum height reasonably practicable as determined by the city, but in no case less than six (6) inches above BFE or existing grade where no BFE exists. The building design and protective measures shall not create adverse impacts on adjacent sites as determined by the city.

(B) Prior to building permit issuance, all new buildings shall pay any required fee or proportionate fair share for the funding of sea level rise projects, if applicable.

(5) Waste Management.

(A) Applicants shall submit a zero-waste management plan to the city, which will cover how the applicant plans to minimize waste to landfill and incineration in accordance with all applicable state and local regulations. Applicants shall show in their zero-waste plan how they will reduce, recycle and compost wastes from the demolition, construction and occupancy phases of the building. For the purposes of this chapter, "zero-waste" is defined as ninety percent (90%) overall diversion of nonhazardous materials from landfill and incineration, wherein discarded materials are reduced, reused, recycled, or composted. Zero-waste plan elements shall include the property owner’s assessment of the types of waste to be generated during demolition, construction and occupancy, and a plan to collect, sort and transport materials to uses other than landfill and incineration.

(6) Bird-Friendly Design.

(A) No more than ten percent (10%) of facade surface area shall have non-bird-friendly glazing.

(B) Bird-friendly glazing includes, but is not limited to, opaque glass, covering the outside surface of clear glass with patterns, paned glass with fenestration, frit or etching patterns, and external screens over nonreflective glass. Highly reflective glass is not permitted.

(C) Occupancy sensors or other switch control devices shall be installed on nonemergency lights and shall be programmed to shut off during nonwork hours and between ten (10) p.m. and sunrise.

(D) Placement of buildings shall avoid the potential funneling of flight paths towards a building facade.

(E) Glass skyways or walkways, freestanding (see-through) glass walls and handrails, and transparent building corners shall not be allowed.

(F) Transparent glass shall not be allowed at the rooflines of buildings, including in conjunction with roof decks, patios and green roofs.

(G) Use of rodenticides shall not be allowed.

(H) A project may receive a waiver from one (1) or more of the items listed in subsections (6)(A) to (F) of this section, subject to the submittal of a site specific evaluation from a qualified biologist and review and approval by the planning commission. (Ord. 1050 § 10, 2018; Ord. 1026 § 3 (part), 2016).
