For purposes of calculating base density, any area of land on a given site that is not potentially developable due to hazards or other environmental and resource factors (including but not limited to areas of sensitive habitat or buffers to that sensitive habitat, steep slopes, significant views, public access ways, or geologic instability) shall not be considered potentially developable lot area and shall be excluded from the base density calculations (i.e., base density shall be determined based only on the potentially developable portion of a given site).
In order to be eligible for a density bonus and other incentives as provided by this chapter, a proposed project shall comply with the following requirements and satisfy: (1) all applicable provisions of the certified LUP and (2) except as otherwise provided by this chapter, all applicable provisions of this zoning code.
A. Types of Projects. The provisions of this chapter shall apply to:
1. New residential projects of five or more dwelling units, regardless of the type of dwelling units proposed;
2. New mixed-use developments which include at least five dwelling units;
3. Renovation of one or more multifamily residential structures containing at least five units so as to result in a net increase of the number of residential units;
4. Development that will change the use of an existing building from nonresidential to residential and that will provide at least five residential units;
5. Developments that include the conversion of at least five residential rental units to ownership housing.
B. Affordability and Age Requirements. Projects receiving a density bonus, incentives, and/or concessions under this chapter shall include at least one of the following:
1. A minimum of ten percent of the proposed dwelling units are for low income households; or
2. A minimum of five percent of the proposed dwelling units are for very low or extremely low income households; or
3. A minimum of ten percent of the total dwelling units in a common interest development, as defined in Civil Code Section
1351, are for persons and families of moderate income; provided, that all units in the development are offered to the public for purchase.
4. A senior citizen project or a mobile home park that limits residency based on age requirements for housing older persons in compliance with Civil Code Sections
51.2,
51.3,
798.76, or
799.5.
5. Length of Affordability. Projects that provide extremely low, very low, and low income units shall provide the units at affordable rents to eligible households for a minimum period of thirty years, beginning at the initial occupancy of each affordable housing unit, or a longer period of time if required by the construction or mortgage financing assistance program, mortgage insurance program, or rental subsidy program. Projects that provide moderate income units in a common interest development shall ensure the initial occupancy of the unit by a moderate income household and the occupancy and resale of the unit shall be governed by an affordable housing agreement. Senior citizen projects shall be restricted to occupancy by senior citizens in perpetuity.
C. Any housing development approved pursuant to this chapter shall be consistent with the certified local LUP policies and with all applicable development standards. Further, all development approved pursuant to a density bonus or other incentive shall be developed in a manner most protective of coastal resources (including but not limited to areas of sensitive habitat, agriculture, steep slopes, significant views, public access ways, or geologic instability). If the city approves development with a density bonus or other incentive, the city must find that the development, with and without the density bonus or other incentive, would have been fully consistent with the policies of the certified LUP. If the city determines that the means of accommodating the density bonus or other incentive proposed by the applicant will have an adverse effect on coastal resources inconsistent with the LUP or the Chapter 3 policies of the Coastal Act, the density bonus or incentive shall not be approved.
D. For development approved within the coastal zone pursuant to this chapter, the required density bonus and any requested incentive(s), concession(s) and/or waiver(s) or reduction(s) of development standards shall be consistent with the Chapter 3 policies of the Coastal Act and all applicable requirements of the certified Half Moon Bay LUP.
