" �GHAU (206) 251 -6222 mar —._ 0 Q74 �- c � CIVIL ENGINEERING, LAND PLANNING, SURVEYING, ENVIRONMENTAL SERVICES N. a �Nc�ma� • 1.0 Introduction and General Information This proposed project is an area of approximately 0.6 acres and consists of an existing abandoned gas station, which is to be remodeled into an ARCO AM/PM Mini-Market. The existing site is currently developed, but is in a very dilapidated condition. The existing features include the gas station, a pump island canopy, surrounding parking, and fencing. The area surrounding the property is heavily forested, except for the right-of-way of N.E. 30th Street and I405. There is a steep slope north of the site. 2.0 Upstream Drainage Basin Analysis The upstream basin that contributes to the site is approximately 0.1 acres in size. Please see enclosed upstream basin map for layout of limits. This basin consists of thick brush and trees, and is a small strip of land between 1405 and the west property boundary. 3.0 On-Site Drainage Analysis Currently, runoff from upstream passes as sheetflow over the western property boundary and into a catch basin, which immediately discharges into a catch basin in the right-of-way of N.E. 30th Street. The roof drains from the existing gas station splash on the existing asphalt payment and sheetflow to the north off the asphalt onto a steep slope, where it eventually winds up in May Creek. The remainder of the site sheetflows in a southerly direction towards the right-of-way of N.E. 30th Street, where it is collected in catch basins just prior to leaving the site. It is then conveyed into the catch basin system in N.E. 30th • Street. 4.0 Downstream Drainage System Description and Problem Screening The downstream system along this project is more clearly defined in the attached downstream drainage map and the attached off-site analysis drainage system table. Please refer to these documents for a detailed description of the downstream system. 5.0 Resource Review The following is a description of each of the resources that was reviewed for the preparation of this Level I Drainage Study: A. Floodplain, Floodway FEMA Maps. This project is not located within a floodplain of a stream, as determined by the FEMA maps. B. Other Off-site Analysis Reports. No other off-site analysis or reports were conducted for this project. C. Sensitive Areas Folio. Each of the sensitive areas folios associated with this area were reviewed. The only sensitive area that was nearby was May Creek, which is a Class I stream. • 5616.010[JPJ/kn] • 6.0 U.S. Department of Agriculture Soil Survey The SCS soil survey for King County classifies the soil at the project site as Indianola loamy fine sand. 7.0 Wetlands Inventory Map It does not appear that wetlands are located on or near this site. 8.0 Conclusion The downstream drainage course from this project site is in good shape. The increase in runoff from the site after redevelopment is negligible, therefore, impacts should be none to minimal. • • 5616.010 [JPJ/kn] • APPENDIX Exhibit A Upstream Basin Map Exhibit B Downstream Basin Map Exhibit C Off-Site Analysis Drainage System Table Exhibit D Assessor's Map Exhibit E FEMA Floodway Map Exhibit F Sensitive Areas Folio Exhibit G USDA SCS Soil Survey • 5616.010[JPJ/kn] • EXHIBIT A UPSTREAM BASIN MAP 5616.010[JPJ/kn] IoA6 I - t / 94 t ' t 1 i 1 j � 1 t � L x � avow % ' K ENNYDALE � � � � i �. � € LEMEHTAKY .- .o'er 222 SCHOOL � l x 1 _ Q � 4 --am � .� ♦ N 1917 4 87.88 EXHIBIT B DOWNSTREAM BASIN MAP 5616.010[JPJ/kn] I 211 OR I 1 4 ❑ ( .I I I r I I f i 11 T R S I C7 1 x x I I TREE!
