These upcoming projects are expected to impact critical <br />areas (wetlands and stream), and, as established by an Environmental Assessment, this mitigation project is <br />needed to offset the impacts of those critical areas. This project will be funded through the FAA AIP program, <br />and is required to follow the environmental requirements of NEPA. The original intent was that this project <br />would follow the standard FAA grant application schedule, with environmental documentation for the project <br />being completed early 2022, and scope and fee for a design grant completed in April of 2022. However, there <br />have been project delays related to a change in permitting, associated with a reduction in wetland impacts from <br />originally expected impacts. As such, Kittitas County (Owner) and Century West have not moved forward with <br />design scoping and development of project fee, as this will be dependent on the outcome of the environmental <br />finding. Furthermore, the FAA will not approve a scope of work until the environmental process is complete. The <br />environmental process is currently in the consultation period and is anticipated to be complete in June of 2022. <br />Planning Level Scope and Fee <br />In an effort to complete the WSDOT Airport Aid application by the May 13" deadline, we have looked at the <br />scope and fee from a high-level planning perspective based on anticipated project elements. We anticipate that <br />the design services for the project will consist of the following tasks: <br />Task 1— Project Management/Administration <br />Task 2 — Survey & Project Base Map Set Up <br />Task 3 — 50% Preliminary Design <br />Task 4 — 90% Design <br />Task 5 — Final Design <br />Task 6 — Bidding Services <br />Based on the anticipated scope tasks and similar projects of this nature, the total project cost is estimated to be <br />around $200,000. With that said, this number will still need to be refined through the final scoping process and <br />validated through the IFE and negotiation process. This is anticipated to be undertaken upon final completion of <br />the environmental process in June of 2022. Once a final fee is identified, this cost documentation is anticipated <br />to be sent to WSDOT Aviation to finalize a final grant amount offer. <br />Century West Engineering 1 22232 171' Avenue SE, Ste. 206 1 Bothell, WA 98021 1 425.286.6602 1 www.centurywest.com <br />
