1.0 PROJECT OVERVIEW 1.1 Purpose and Scope This stormwater site-plan report addresses the design of the stormwater system supporting the proposed teaching facility improvements at Everett Community College in the City of Everett, Washington. The project site is located at approximately 952 North Broadway on the Everett Community College campus. A vicinity map is provided in Appendix A. The proposed development encompasses four separate parcels, which are currently occupied by a college-owned parking lot, a motel and associated parking lot and swimming pool, a single-family home, and Frasier's Sports Bar. See the Existing Conditions Maps in Appendix A for more information. On the two larger parcels, which contain the parking lot and motel, a two-story nursing and health sciences building will be constructed. On the smallest parcel, occupied by the single- family home, a new pedestrian walkway connecting the proposed building to Broadway (to the west)will be constructed. For the purpose of this stormwater report, these parcels will be referred to as the Building site. The fourth parcel, which lies to the southwest of the intersection of 10th Street and North Broadway(and currently occupied by Frasier's Sports Bar), will contain a new parking lot. The Everett Community College refers to this parking lot as Surface Parking Lot"M". This report will refer to Surface Parking Lot"M"as the 10th Street Parking site. All existing parking lots, buildings, and associated utilities will be demolished prior to new construction. Pedestrian facilities, landscaping areas, parking, and supporting utilities for the proposed construction are considered part of this project. See the Developed Conditions Maps in Appendix A for more information. To manage stormwater from the developed site, several surface landscaping features (such as rain gardens) and an underground infiltration/detention pipe will be constructed. All drainage systems have been designed to meet the City of Everett stormwater management requirements. • 1.2 Existing Conditions Summary 1.2.1 Land Cover As previously stated, the Building site is occupied by an asphalt,parking lot, a motel and the associated parking lot and swimming pool, and a single-family home. Existing landscaping features are minimal. This area is approximately 2.86 acres and approximately 73 percent impervious. The 10th Street Parking site is currently occupied by Frasier's Sports Bar and the associated parking lot. This site is effectively 100 percent impervious and is approximately 0.42 acre in total area. See the Existing Conditions Maps in Appendix A for more information. r SiteReport Everett community College 011100 Index Hall Replacement&Surface Parking Lot"M" 1 209459.10/209459.11
