Site Review. Site review, in accord with Chapter 18.75, will be required for developments having three or more units per parcel and in addition to the provisions of Chapter 18.75 a site plan shall be submitted which shows the scale and location of all buildings, parking areas, driveways, recreational facilities, building elevations, landscaping, screening and fencing. In addition to the provisions of Chapter 18.75, the administrator may require the following measures to mitigate the impact of development upon adjacent RR, RL, or RM districts in developments having three or more dwelling units per parcel: additional setbacks, buffers, fencing, screening, landscaping to conform with the character of adjacent districts; limiting building height to one story to conform with the character of the adjacent districts; and exterior architectural design to conform with the character of the adjacent districts.

Each development must provide for usable common open space or a public park in an amount determined through review pursuant to Chapter 16.04. The city and developer may agree to a cash payment to the city in lieu of the provision for open space; provided, that such payment is sufficient for the city to construct or enhance a park elsewhere in the city. Any agreement between the city and the developer shall comply with RCW 82.02.020 as now codified or as hereafter amended. If the open common space is private, it must be concentrated in a large, homogenous, centrally located parcel designed to provide for active or passive recreation. Private common open space shall not include:

The maximum permitted number of dwelling units for any development in the RH zoning district is determined by dividing the gross area of the parcel in square feet by forty-three thousand five hundred sixty square feet, multiplied by the allowed maximum density of fifteen. The closest or next lowest whole number is the permitted maximum number of lots. If the maximum density limitation would prevent a triplex from being built in the RH zoning district, on a lot which was legally existing at the time this section was enacted, then maximum density shall not apply to that lot, and a triplex may be constructed on such lot.
