STORMWATER SITE PLAN EVERETT COMMUNITY COLLEGE HOUSING - BROADWAY MR2: CONSTRUCTION STORMWATER POLLUTION PREVENTION SEPTEMBER 11, 2015 PAGE 4 Everett Community College Housing project located at the SW corner of the intersection of North Broadway and 10th Street, see Figure 1: Vicinity Map. The site consists of three tax parcels, (00385422101700, 00385422101800, 29051700204700), each currently containing a single family house, two of which have garage buildings, see Figure 2: Existing Site Map. The proposal is to remove the existing structures and redevelop the site as a multi-story building for students at Everett Community College. Nine parking stalls will be constructed along the alley to the west. See Figure 3: Developed Conditions. The construction site has the following characteristics: Disturbed Area: 16,900 sf Soil Type: Gravelly sandy loam Average slope: 5% Critical Areas: None 1. CONSTRUCTION STORMWATER POLLUTION PREVENTION ELEMENTS A Construction Storm water Management Plan has been prepared as part of the construction drawings and is submitted for review and approval by the City of Everett. The 12 Required Elements are addressed as follows: Element #1: Mark Clearing Limits The construction plans delineate the limits of the clearing for the site. These will be located in the field prior to clearing taking place. Element #2: Establish Construction Access With nearly the full site dedicated to building construction, no construction access is feasible. Access will be from the alley and exposed surfaces between the building construction and the alleyway will be stabilized with rock. Element #3: Control Flow Rates The site has no requirement to control flow rates Element #4: Install Sediment Controls The construction sequence lists the schedule for installation of erosion control measures. Element #5: Stabilize Soils In planting areas the exposed soils will be stabilized per the Landscape Plan prepared for the project. The building will stabilize most of the site. Temporary stockpiles will be covered with plastic. I': \1'��rk Prujr�h`"'Oli 15-I"/ll Kcv - l3rund��;n'('I' �)O('ti licv 13r��a�l��':p' l)r;iina�r IS-171Ldu�.
