THE CITY COUNCIL OF THE CITY OF KENT, WASHINGTON DOES HEREBY ORDAIN AS FOLLOWS: Section 1. A new section 15.08.230, Kent City Code, is added as follows: 15.08.230 SOLAR ACCESS SETBACK - PURPOSE The purpose of the Solar Access Setback provisions is to provide a reasonable amount of solar access, wherever feasible, to lots in the City so that the economic value of solar radiation falling on those properties will be preserved, investments in solar equipment will be secure, and the option to use solar energy will be preserved and encouraged, as provided for in RCW 64.04.140, Section 2. A new section 15.08.232, Kent City Code, is added as follows: 15.08.232 SOLAR ACCESS SETBACK - APPLICABILITY A. All structures over six feet in height proposed on properties in the Agricultural (A-1), Residential Agricultural (R -A), Single Family (R1-20, R1-12, R-1 9.6, R-1 7.2) zones shall comply with Section 15.08.234, except as provided in Section 15.08.232 B. The provisions of this section shall not exceed the yard and setback requirements of the underlying zone. B. A new or remodeled structure is exempt from Section 15.08.234 provided: 1. Property Within a Solar Envelope. The struc- ture is located on property that is subject to a Solar Envelope which complies with the Solar Access Performance Standard for New Development. [This exemption is reserved until such time as Solar Access Performance Standards are adopted.] 2. Existing Shade Conditions. The structure causes a shadow at noon on January 21 which is not higher or wider, at the northern lot line than the shadow caused at the northern lot line on noon on January 21 by an existing structure. 3. Actual Shadow Height. The structure causes a shadow at noon on January 21 that is not higher than that allowed for that lot by Section 15.08.234. C. Proof of existing shade conditions and/or shadows within the tolerance of Section 15.08.234 shall be provided by the applicant. The Planning Department shall assist the applicant in 'obtaining the necessary information. Section 3. A new section 15.08.234, Kent City Code, is added as follows: 15.08.234 SOLAR ACCESS SETBACK - CALCULATION A. Solar Factor. 1. The Planning Director, or his/her designee, shall determine the Solar Factor for a lot based on Table 1, attached hereto and by this reference incorporated herein, or the formula set out in Section 15.08.234 A.2. This standard permits a lot to be developed with a structure with its highest shade producing point 24 feet high, provided that point is situated south of the northern lot line a minimum of one-half (1/2) of the north -south dimension of the lot. 2. N [ (1/.42 + P) / 2.38 ] B. Solar Setback. The highest shade -producing point of a structure shall be set back from the northern lot line not less than: - 2 - 1. (H - 6) / (.42 + P), for a lot with a Solar Factor equal to or greater than 85; or 2. (H - 14) / (.42 + P), for a lot with a Solar Factor equal to or greater than 47 and less than 85. 3. For any lot with a solar factor less than 47, the shadow of a structure shall not be greater than the shadow cast by an 18 foot pole located one half the distance through the north -south dimension of the lot. C. For purposes of this section, H is the height of the ;highest shade producing point of the structure above grade and P is the solar slope of the lot. N is the north -south lot dimension{ i Section 4. Chapter 15.02, Kent City Code, is amended to add the following: 15.02.187 HIGHEST SHADE PRODUCING POINT The point of a structure which casts the longest shadow at noon on January 21. 15.02.287 NORTHERN LOT LINE A lot line or lines less than 45 degrees southeast or ,southwest of a line drawn east -west and intersecting the northern- most point of the lot. If the northern lot line adjoins any unbuildable area (e.g. streets, alleys, public rights of way, parking lots, common areas) other than a required yard area, the northern lot line shall be that portion of the northerly edge of the unbuildable area which is due north from the actual northern lot line of the applicant's property. 15.02.288 NORTH -SOUTH LOT DIMENSION The average distance between lines from the corners of the northern lot line south to a line drawn east -west and inter- secting the southernmost point of the lot. - 3 - 15.02.496 SOLAR FACTOR A number assigned to every lot which is based on the lots north -south lot dimension and solar slope as determined by Table 1, Section 15.08.234. 15.02.497 SOLAR SETBACK A setback from the northern lot line equal to the distance between the northern lot line and that point on grade immediately beneath the highest shade producing point of a structure. 15.02.498 SOLAR SLOPE The average of slope lines from the corners of the northern lot line south to a property line. The slope of a single line is determined by dividing the vertical distance between the two end points by the horizontal distance between the same two points. North facing slopes will have a negative (-) value. South facing slopes will have a positive (+) value. Section 5. The provisions of this ordinance are declared to be separate and severable. The invalidity of any clause, sentence, paragraph, subdivisions, section or portion of this ordinance, or the invalidity of the application thereof to any person or circumstance shall not affect the validity of the remainder of the ordinance, or the validity or its application to other persons or circumstances.
