Table of Site Design Standards and Subdivision Requirements. The provisions of this chapter and the requirements in Table 5-1, Site Design Requirements and Standards, and Table 5-2, Subdivision Requirements[1],[2] are hereby established for all development in the zoning districts indicated.

Development on Nonconforming Lots. Development on nonconforming lots is governed by this section and Section 17.19.040. Except as limited by this title, any permitted use may be erected on any lot legally created prior to the adoption of the ordinance codified in this title. Such development and structures are subject to the following additional provisions:

Maximum lot coverage is the percentage of net land area of a site that can be covered with the structures and other impervious surfaces. The maximum lot coverage in each district is shown in Table 5-1.

In the SR and R-1 districts, this standard is intended to protect the open character of each district, and ensure that land is available to accommodate septic tanks and drainfields. The intent in the R-2 and R-3 districts is to provide areas for landscaping and recreation. Maximum lot coverage requirements in the commercial districts are intended to promote development consistent with the character of the district, protect setbacks, and provide the opportunity to integrate open space and landscaping plans into the design and placement of the structure and off-street parking.

Structure setbacks are the minimum structure setbacks permitted in a particular zoning district with Class (1) review. In the residential district, structure setbacks are intended to provide privacy, light, air and emergency access. Setbacks along easements and rights-of-way are intended to minimize the impacts from traffic on adjoining property owners. In the commercial districts, building setbacks provide visual clearance along streets and areas for site screening and landscaping. Structure setbacks are required in the industrial districts to provide fire protection, emergency access, and to reduce impacts on adjacent districts of lower intensity. No structure shall be built or located on or in a utility easement unless written permission is obtained from the easement grantee.

Setbacks for Residential Accessory Structures. The minimum setback for residential accessory structures in the residential districts shall be at least five feet from the side property line, five feet from the rear property line, and up to, but not within, the required front yard; provided, that the accessory structure(s) shall not encroach on a public easement and applicable street setbacks are observed. In the residential districts an accessory structure not requiring a building permit may be placed up to the side or rear property line if the structure will not encroach on a public easement and applicable street setbacks are observed.

Maximum building height is intended to maintain building heights compatible with the character and intent of the district. The maximum building height in each district is shown in Table 5-1.

Fences and Walls–Standard Height. The following provisions shall govern the location and height of fences and walls:

Access Required. All new development shall have a minimum of twenty feet of lot frontage upon a public road or be served by an access easement at least twenty feet in width. The purpose of this standard is to provide vehicular access to all new development. Provided, the construction of single-family and two-family dwellings on existing legally established lots is exempt from the requirements of this section.

Door Openings. All dwellings shall have a front entry door which faces, or opens up to, the street on which the residence is addressed for tax and property identification purposes. Such front door shall open directly to the residence and not be part of an addition or improvement designed to avoid the requirements herein.

Development Requirements for Public Facilities Zone. Due to the unusual character and wide range of uses allowed in the PF zone, development restrictions may vary depending on the use proposed for the PF zone. Staff shall use the standards presented in Table 5-1, Site Design Requirements and Standards, as guidelines when reviewing projects. However, staff may deviate from these standards on a case-by-case basis as needed to meet the intent of the PF zone.

Table of Subdivision Requirements. The provisions of this section and the requirements set forth in Table 5-2, Subdivision Requirements,[1] are hereby established for all subdivisions in the zoning districts indicated. In the case of conflict between the text and tables, the text shall govern.

Maximum number of dwelling units permitted per net residential acre is used to determine the maximum number of dwelling units permitted within a single subdivision, short subdivision, manufactured home park, multifamily development, or planned residential development.

Minimum lot size is the smallest lot size permitted in a particular zoning district when land is subdivided, short platted, re-subdivided, or when lot lines are adjusted. No lot shall be created that is smaller than the applicable minimum lot size standard established in Table 5-2[3]. In residential districts, this standard is intended to maintain the residential character of the area and will vary by dwelling type, the suitability of land for development, and the type of water and sewer system. Following are the minimum lot size requirements in the residential districts, except when the Yakima health district determines that a larger area is necessary for the safe installation of an approved water supply and sewage disposal system.

The smaller lot size for zero lot line, attached and multifamily dwellings does not permit an increase in the maximum number of dwelling units per net residential acre established in subsection B of this section. Any lot created by zero lot line, attached and multifamily dwellings shall be so designated on the face of the plat or short plat.

In the local business district, the minimum lot size is intended to maintain the character of the district and provide adequate space for off-street parking and landscaping. The minimum lot size in the small and large convenience center districts and industrial districts is intended to accommodate the large uses permitted in these districts and maintain vacant land in relatively large parcels that can be easily assembled when development is proposed.

Standard lot width is the minimum lot width generally permitted in a particular zoning district. The intent of this standard is to prevent irregularly shaped lots, and to control access to rights-of-way.

Concurrent Subdivision and Zoning Review Required. Any application for a long subdivision which proposes a use or configuration of land or improvements which would require Class (2) or (3) review under this title shall, at or prior to the filing of such application, also file an application for such review under this title. Such application shall be heard by the city council concurrently with the subdivision application using the procedures for Class (3) review.

All corner lots at unsignalized street intersections or railroads shall maintain, for safety vision purpose, a vision clearance triangle. The vision clearance triangle shall consist of the area bounded by the centerlines of the adjacent intersecting streets extending along the centerlines eighty feet from the point of intersection, and a straight line connecting said latter points; provided, that, when either of the intersecting streets has or will have eighty feet of right-of-way, the vision clearance triangle shall be the area bounded by the centerlines of the adjacent intersecting streets extending along the centerlines one hundred feet from the point of intersection, and a straight line connecting said latter points. Nothing within the vision clearance triangle shall be erected, placed, planted or allowed to grow in such a manner as to materially impede vision between the heights of two and one-half and ten feet above the centerline grades of intersecting streets (and/or railroads) or the future intersections of centerlines where improvements are programmed with the six-year road improvement program, on file in the Wapato city public works department.

Driveway Curb Cuts. A clear view triangle shall be maintained at all driveways and curb cuts for vision safety purposes. One angle shall be formed by lines A and B which are adjacent to the street and driveway. The sides of the triangle (A and B) forming the corner angle shall be fifteen feet in length. The third side of the triangle shall be a straight line connecting points C and D. No sign or associated landscaping shall be placed within this triangle so as to materially impede vision between the heights of two and one-half and ten feet above the centerline grade of the street.
