18.32.010 Purpose.

The main objective and intent of these zones are to create and maintain the type of living environment which meets the standards for single-family residential development. A further related consideration is to establish a residential density which makes it possible to more efficiently and economically install and maintain public service facilities. This includes taking into consideration the natural constraints on development, existing and potential views, and the provision of adequate open space within and between subdivisions.

18.32.052 Density range (units per net acre).

Six to nine

Four to seven

Three to five

A.    Net density shall be calculated per developable lot, and shall exclude conservation easements, community tracts, rights-of-way, and other required infrastructure. One reserve tract containing one or less developable lots may be established for the purpose of future subdivision and shall not be included in net density calculations; provided, that they are clearly identified as such on the face of a recorded subdivision, short plat, or lot line adjustment. A reserve tract may be developed with one residential unit or less, pursuant to the requirements of FMC 18.32.120. Each residential unit associated with a duplex or single-family attached duplex shall be considered a single-family residence for the purpose of calculating density for new residential subdivisions.

1.    Land that consists of lots devoted to uses other than residential and associated uses, including but not limited to churches, schools, and support facilities, shall not be included in density calculations.

B.    In situations where density requirements and lot size, shape, topography, or location result in a subdivision that cannot possibly meet the density requirements, a reduction in minimum density may be granted by the Community Development Director if all of the following criteria can be met:

1.    The lot to be subdivided must be less than or equal to one-half acre in total area.

2.    The reduction in minimum density may not result in more than one additional single-family dwelling.

3.    The reduction in density will not result in a density that is less than 85 percent of the minimum density required in the applicable zoning district.

4.    The conditions unique to the site (size, shape, topography, etc.) are not the result of actions by the applicant.

5.    In no event may a reduction in density be granted if it would result in a use that would not be allowed as a permitted, accessory or conditional use in the zone in which the property is located.

C.    Density Rounding. When the calculation of density ranges for specific developments does not result in a whole number, the Community Development Director may round densities to the closest whole number. However, the Community Development Director may not allow densities to be created through rounding that are outside of the required density range.

18.32.110 Minimum open space.

 

A.    Purpose. The community seeks to create and preserve open space within subdivisions while encouraging reasonable urban densities. Open space establishes a sense of place, provides visual separation, creates formal and informal recreation opportunities for children and adults, maintains property values, and enhances public safety by providing off-street recreation opportunities.

B.    Requirements. The City has established minimum open space requirements that can be met on a lot-by-lot basis or through development-wide compliance. For the purpose of this requirement, open space shall be a contiguous area with no dimension less than 15 feet that consists of natural vegetation, landscaping, or recreation areas. Front and back yards may be considered open space, exclusive of paved driveways or parking areas, accessory buildings, or covered patios.

1.    Lot-by-Lot Compliance. A minimum of 20 percent of each lot shall be devoted to a contiguous area of open space as defined in the requirements element of this section, subject to review for compliance with applicable laws related to nexus and proportionality. No portion of this open space may have a dimension of less than 15 feet.

2.    Development-Wide Compliance. The minimum open space requirement may be measured on a development-wide basis as opposed to a lot-by-lot basis. Under this option, individual lots may be developed with as little as 10 percent of total lot square footage in open space; provided, that the development as a whole reserves an area equal to 20 percent of the total lot area for open space. Common open space created under this modification shall:

a.    Serve all lots within the subdivision, particularly those lots that cannot meet the minimum lot-by-lot requirements in subsection (B)(1) of this section;

b.    Be designed to reflect its intended use by including picnic areas, trails, children’s play areas, sport courts, or interpretive exhibits;

c.    Consist of a contiguous area and have no single dimension of less than 25 feet, with the exception of trails which may be reduced in width; and

d.    Have a minimum size equal to the total square foot reduction below the open space standard for every lot in the development.

3.    Provisions Applicable to Both Lot-by-Lot and Development-Wide Compliance.

a.    Environmentally sensitive areas, buffers, front and rear lot setbacks, swimming pools, sport courts other than driveways, recreational buildings, swimming pools, golf courses, uncovered gardens, uncovered outdoor patios and similar structures or facilities may be used to meet the minimum open space requirement.

b.    At least 25 percent of the minimum open space requirement shall be outside of wetlands, streams, lakes, and sensitive areas.

c.    Open space within a development shall be available for common use by the residents and tenants of the development. All trails shall also be made available to the general public. Critical area buffers and critical areas themselves may be included in open space calculations, but may not be used for recreation.

(Ord. 2173 § 1 (Att. 1), 2021; Ord. 2151 § 1 (Exh. 2), 2020; Ord. 1988 § 1, 2017; Ord. 1969 § 5 (Exh. 6), 2016; Ord. 1851 § 9, 2014)

18.32.120 Reserve tract.

 

For the purposes of this chapter, “reserve tract” is defined as that portion of a proposed subdivision or short plat which is reserved for future subdivision in addition to any planned phasing that is vested to the original preliminary plat or approved short plat. A reserve tract is intended to enable the subdivider to reserve a portion of the land to be subdivided until such time as future subdivision is proposed, and shall not be required to install more infrastructure than is necessary to serve a maximum of one residential unit within the tract. Reserve tracts may be permitted subject to the following restrictions:

A.    Land within the reserve tract shall not be included in calculations for lot averaging, minimum or maximum densities, or the total number of lots that may be established within the proposed subdivision.

B.    Parcels of less than one acre in size shall not be eligible to establish a reserve tract.

C.    Reserve tracts of one-half acre in size or less shall not be permitted.

D.    Reserve tracts may be considered a building lot; provided, that no more than one residential unit shall be allowed on the reserve tract, and this unit shall be included in density calculations for subsequent subdivisions.

E.    The requirements of this section shall be recorded as a deed restriction at the time of filing of the final plat or short plat, and shall constitute an agreement between the City of Ferndale and the owner of record. Said deed restriction may be amended by mutual agreement between said parties after review for consistency with all applicable regulations in place at the time a request for amendment is received.

F.    An applicant who does not wish to fully develop a property within the time frame provided by an approved preliminary plat may find that the creation of a reserve tract is an appropriate alternative. An applicant who wishes to entitle the entirety of a property through one preliminary plat to be constructed in phases is not obligated to or prevented from establishing reserve tracts for these subsequent phases.
