304 SE EVERETT MALL WAY PANERA BREAD 2025-07-25

Panera Bread Stormwater Management Report Everett,WA SECTION 1 - Project Overview Existing Conditions Property is located at the southeast corner of the intersection of Everett Way SE and 3`d Avenue (304 SE Everett Mall Way), See Figure 1. Currently, the site hosts a demolished gas station, a closed oil/lube shop and an operational self-serve carwash. The bulk of the site is impervious with a small amount of landscaped area. The site is a lease area of an overall shopping center which consists of a McDonald's restaurant and in-line retail establishments. The topography of the ground, as denoted in Figure 2, indicates that the project site receives some overland sheet flow runoff from the neighboring McDonald's restaurant. Since this area is paved, the contributing flow from the existing McDonald's has been taken into consideration in design of the storm system. Soils Conditions A detailed geotechnical study of the site was performed by Krazan &Associates, Inc. to determine the properties of the subsurface soils.This geotechnical report, dated August 24, 2012, project number 092-12004, indicates that beneath the existing pavement, the surficial soils consist of fill overlying native, medium dense native silty sand with gravel (glacial drift), and dense to very dense native silty sand with gravel (glacial till). Additional information about the soils encountered is presented in the logs of the soil borings in Appendix B. Wells, Septic Tanks and Fuel Tanks Based upon field reconnaissance and the environmental review, it appears that one underground tank have been located on the property. The landlord is responsible for the removal of this tank in accordance with federal, state, and local regulations. If at a later date any wells or additional tanks are discovered on the property, it will be removed in accordance with all regulatory requirements, local, state and federal. Proposed Development The proposed project is to construct a new 4,300 SF restaurant with a drive-thru and its associated infrastructure improvements on the 0.81 acre site. Approximately 0.07 acres of the land of the adjacent shopping plaza will be disturbed in order to reconfigure the parking area that abuts the subject site so that the finished plaza has appropriate vehicular circulation. An additional 0.06 acres of right-of-way will be disturbed to remove an existing driveway, construct Core States Group Page 5
