EXHIBIT A WORK ORDER FORM DIKING IMPROVEMENT DISTRICT NO. 5 SMITH ISLAND ADVANCE MITIGATION SITE YEAR 5 MONITORING SCOPE AND FEE ESTIMATE INTRODUCTION AND PROJECT UNDERSTANDING GeoEngineers, Inc. (GeoEngineers) is pleased to present the following scope and fee estimate to the City of Everett (City) for the Year 5 monitoring of Diking District No. 5’s (DID5) Smith Island Advance Mitigation Site (AMS). Following preparation of the Year 3 summary report and coordination with Washington State Department of Ecology (Ecology) on how the report content addressed the status of performance standards, the City requested Geoengineers to prepare a scope of work to complete the Year 5 monitoring for the AMS. The scope of work is based on the monitoring methods described in the AMS, the coordination with Ecology and includes a pilot monitoring program to assess cattail (Typha sp.) populations. GeoEngineers understands the City and DID5 plan to share this scope of work with Snohomish County (County) to discuss monitoring and reporting efforts described in their Smith Island Inter-Local Agreement. The scope of work has been prepared so that portions of work can be broken out and performed separately. If work is broken out, the scope includes a contingency task to cover the additional effort associated with incorporating data from others and performing quality control. The contingency task (Task 7) will require written authorization from the City to be activated. SCOPE OF SERVICES Task 1 – Project Management Monthly 1-hour coordination meetings with client. Contract administration including file set up, contract processing, monthly budget review, progress report, and invoice preparation. Task 2 – Drone Data Collection An aerial photograph and elevation point data collection of the AMS will be taken by drone during a low tide of -2 feet North American Vertical Datum of 1988 (NAVD88) or lower to capture the extents of channel, mudflat, and vegetated areas. Elevation point data collection accurate to an inch will be collected to develop site contours and will be verified by collecting elevation data using handheld global positioning system (GPS) units on the ground at strategic locations. The aerial low tide photograph will be georeferenced and used to inform mapping the size and distribution of the vegetation communities, mudflat, and tidal channels based on digital processing of their visual signatures.
