Exhibit A (Scope of Work) <br />SCOPE OF WORK <br />GeoEngineers, Inc. (GeoEngineers) appreciates the opportunity to provide <br />hydrogeologic services for the Edgewater Park property located at 3731 Mukilteo <br />Boulevard in Everett, Washington. Hydrogeologic services include completing <br />infiltration testing at the site, preparing an infiltration evaluation report, and providing <br />consultation for the project. The scope of services is presented below. <br />Task 100. Pilot Infiltration Testing <br />1.Review sections of the 2019 Washington State Department of <br />Ecology Stormwater Management Manual for Western Washington <br />(SWMMWW) pertaining to infiltration testing and design <br />requirements. <br />2.Complete three small-scale pilot infiltration tests (PITs) in general <br />accordance with the 2019 SWMMWW. The PITs will be completed <br />with the assistance of an excavation contractor under subcontract to <br />GeoEngineers who will excavate the test pits for the PITs. Water for <br />the tests will be provided by the excavation contractor using water <br />totes. The excavation subcontractor will provide hosing to run water <br />from the totes to the PIT locations. The PITs will also be observed by <br />an engineer or geologist from our firm who will log the subsurface <br />conditions and conduct the testing. The following tasks and <br />assumptions are included in this scope item: <br />+ Review available survey for the site. <br />+ Work with the City of Everett to mark the test pit locations, <br />coordinate schedule, access, and right-of-entry. <br />+ Locate and clear existing utilities within the PIT areas. We will <br />initiate an underground utility location check, which will require a ½ <br />day site visit and at least 3 days prior to excavation. We will also <br />subcontract a private utility locating service. <br />+ Excavate three test pit excavations to observe subsurface <br />conditions within the proposed infiltration areas and collect <br />representative soil samples for laboratory testing. <br />+ Complete three PITs at the project site within the proposed <br />infiltration areas. The infiltration test locations have been provided by <br />the City of Everett. Recommended testing depths are 3 to 4 feet with <br />over-excavation to a depth of up to 6 feet. The purpose of the PITs is <br />to evaluate infiltration potential and develop design infiltration rates. <br />We estimate that the testing will require one field staff and 2 days to <br />complete the excavation, testing, and backfilling. W e propose to <br />complete the two PITs located on the eastern portion of the site at <br />the same time in 1 day. <br />+ Backfill the PIT test pits with material removed from the test pits <br />and tamping the soil in place with the excavator bucket. We will
