1. PROJECT OVERVIEW This document is intended to provide the engineering information necessary to support the building permit application for a new SFR and paved driveway in the City of Everett. The site covers 0.20 acres. The existing site is currently partially developed with some existing gravel and lawn. The proposed disturbance area will cover approximately 5,725 sf. The proposed SFR will be set approximately 20 feet from western property line and 5 feet from the southern property line. Access to the new SFR will be taken from the proposed paved driveway which will take access from the existing roadway to the east (271 Dr SE). The parcel is currently undeveloped and is surrounded by developed parcels. The slope of the site in the area of the proposed SFR and driveway is mild and averages approximately 5 percent to the east. This development proposes to construct a new SFR with a paved driveway taking access off of 27th Dr SE. The total new plus replaced impervious surfaces equal 3,178 sf (0.07 acres). Roof runoff from the SFR roof will be infiltrated via an infiltration trench. The driveway surface proposed for this project will be infiltrated using an infiltration trench. All drainage improvements have been designed to meet or exceed the 2014 DOE Stormwater Management Manual The project location is 10304 27th Dr SE, in the City of Everett, and in Section 20, Township 28N, Range 5E.
