Box 547 <br />Anacortes, Washington 98221 <br /> <br />SUBJECT: STORMWATER PLAN SUBMITTAL REVIEW, 4201 O AVENUE <br />CITY OF ANACORTES, SKAGIT COUNTY, WASHINGTON <br />G&O #22411.03 <br /> <br />Dear Mr. Lange: <br /> <br />The proposed project consists of a previously constructed gravel driveway that contains <br />6,449 square feet of new impervious surface. The applicant notes that the project is flow <br />control exempt. In addition, it is noted that runoff on the new driveway is subjected to <br />sheet flow dispersion (a flow control-related BMP) and that water quality will be <br />provided through vegetated areas adjacent to the driveway for a length longer than the <br />required 20 feet. <br /> <br />We find this meets the City’s standards. Please contact me if you have any questions <br />regarding these comments. <br /> <br />Sincerely, <br /> <br />GRAY & OSBORNE, INC. <br /> <br /> <br /> <br />Stacey A. Clear, P.E. <br /> <br />SAC/hh <br />Encl.
