Development standards for residential, low density (RL) districts are as follows:
A. 
Minimum lot area: ten thousand square feet unless otherwise approved with clustering pursuant to Chapter 18.59.
B. 
Minimum lot width: seventy-five feet unless otherwise approved with clustering pursuant to Chapter 18.59.
C. 
Minimum setbacks: street frontage, twenty feet; side, five feet on one side and ten feet on the other or garage side; rear, twenty feet. Setbacks may be altered if approved with clustering pursuant to Chapter 18.59.
D. 
Maximum lot coverage: sixty percent of the parcel size, not including any portion of the adjacent street right-of-way.
E. 
Maximum building height: thirty-five feet. Structures higher than thirty-five feet require approval of a conditional use permit in accordance with Section 18.75.050.
F. 
Off-Street Parking. Off-street parking shall be provided in accordance with Chapter 18.63.
G. 
Design review in accordance with Chapter 18.07.
H. 
Provisions for Open Spaces and Recreation Areas. Each development of five lots or more 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:
1. 
Areas reserved for the exclusive use or benefit of individual property owners; and
2. 
Dedicated vehicular and pedestrian right-of-way, easement or off-street parking areas. There must be adequate provisions for permanent retention and maintenance of such private common open space.
I. 
Unless otherwise approved with clustering pursuant to Chapter 18.59, the maximum permitted number of lots/dwelling units for any development in the RL zone 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 four and one-half. The closest or next lowest whole number is the permitted maximum number of lots. If the maximum density limitation would prevent a single-family dwelling unit from being built in the RL zone, on a lot which was legally existing at the time this section was enacted, then maximum density shall not apply to that lot.

If any section, subsection, sentence, clause, paragraph, phrase, or word of this chapter should be held to be invalid or unconstitutional by a court of competent jurisdiction, such invalidity or unconstitutionality thereof shall not affect the validity or constitutionality of any other section, subsection, sentence, clause, paragraph, phrase or word of this chapter.
