18.105.010 Basic characteristics of a residential site.

A lot or parcel to be developed for residential use shall comply with the following:

(1) Lot Size and Shape. The residential lot or parcel area shall be not less than 6,000 square feet. The size, width, shape and orientation of the lot or parcel shall provide a building site that is appropriate in relation to adjacent land divisions, solar access, flood and other hazard conditions and the environmental protection requirements of this title.

(2) Side Lot Lines. As far as practical, the side property line of a lot or parcel shall run at right angles to the street upon which it faces, except that on a curved street the side property line shall be radial to the curve. Where solar orientation is a consideration, a side lot line may vary from the above requirement if the variation will improve solar access.

(3) Through Lots. Through lots or parcels shall have a rear setback area equal to the required front setback area within which no structure shall be erected. Access to through lots or parcels shall be via the street frontage on the front side of the lot or parcel; there shall be no right of access to a street via the rear frontage. [Ord. 508 § 5.07.0, 1982].

18.105.020 Limitation on buildings.

In residential zones there shall be permitted only one main building on a lot; however, multiple-family and single-family attached dwellings that are all part of a single development may be excepted. [Ord. 508 § 5.07.1, 1982].

18.105.030 Design standards for hillside development.

Building construction in the residential hillside district will be approved under conditions that do not adversely affect the visual and physical identity of the hills. The grading of land and the orientation and design of a building will avoid creating conditions that will cause erosion or modify drainage patterns. Where there is some risk of these conditions occurring, certification will be obtained in accordance with MCMC 18.150.030(15) or (16) to ensure that the design and control measure will comply with this provision. The design standards specified herein shall be utilized in conjunction with the residential hillside district regulations and the protection standards for natural features.

(1) Maximum retention of natural topographic features and qualities is encouraged to avoid modification of hill areas that create unnatural geologic conditions or visually unappealing hillside configurations.

(2) In the residential hillside district, buildings will be spaced and have roof types and exteriors to blend with the environment.

(3) Construction work shall be scheduled and conducted to avoid erosion and to permit any control measure involving vegetative plantings to take place during optimal revegetation periods and to avoid unprotected disturbance of the ground during the storm season. Temporary stabilization measures may be needed until permanent installations are accomplished.

(4) An access route within the residential hillside district will comply with the following:

(a) A road or pedestrian trail will be stabilized by planking, gravel or pavement.

(b) Vehicle access points to the development will be spaced the maximum distance that still permits reasonable access and will be located and designed to preserve the natural form and profile of the hillside affected by the access route.

(c) A roadway will be built without installation of fill or other forms of terracing unless certification is obtained assuring that such conditions will not be detrimental to the area or create unwarranted maintenance problems.

(d) The planning commission may authorize narrower pavement widths combined with parking bays, turning circles, and/or one-way traffic patterns to overcome a disadvantage of topography and to implement subsection (1) of this section.

(5) Access to known wildlife nesting and breeding habitats will be restricted. [Ord. 508 § 5.07.2, 1982].
