Exhibit A — Scope of Mork <br />REECER CREEK FLCODPLAIH MAPPING AND LEVEE <br />CERTIFICAT!0R9 SUPPORT SERVICES <br />Scope of Work <br />Aspect Consulting LLC, February 4th, 2020 <br />Background <br />Aspect Consulting, LLC (Aspect) nas been selected by the City of Ellensburg to provide support <br />services related to floodplain mapping and the potential certification of set -back levees along <br />Reecer Creek. The Kittitas County Flood Control Zone District (FCZD) is completing a flood <br />mapping project that includes lower Reecer Creek.. The County's flood model does not currently <br />include floodplain changes north of Dolarway Road that are being designed by the City, <br />specifically a set -back levee, bridge, and network of floodplain swales. It is important for the <br />County's flood mapping project to be coordinated with, and account for the City's planned <br />improvements in the area. In addition, FEMA's levee certification standards have changed <br />since the lower Reecer Creek levee was constructed. The new standards affect how the existing <br />and planned levees will be included in the FCZD's flood model and whether they will be formally <br />recognized by FEMA and the National Flood Insurance Program (NFIP) as providing protection <br />during a 100 -year flood to lands outside the levees. City coordination with the FCZD and FEMA <br />along with a systematic review of the levee standards, elevations, and tie-in locations is needed <br />to identify and quantify changes that may be needed to meet current levee certification <br />standards. <br />Phased Support Services <br />Aspect recommends a phased approach for the floodplain mapping and levee certification <br />support services: <br />1. The initial phase will involve: coordinating with the City, FCZD, and FEMA regarding <br />levee construction and certification standards, modeling methods, planned <br />improvements; and potential changes needed to meet FEMA's standards. This phase <br />will also involve providing levee, bridge, and floodplain Swale design information to the <br />FCZD and interactions with the FCZD and their consultant regarding updated flood <br />modeling approaches and results. <br />2. A second phase would involve assembling or developing data and documentation to <br />support a request to FEMA for a modification of normal riverine levee freeboard <br />standards and final determination of design changes to the existing and planned levees <br />and related structures to meet FEMA's standards. <br />3. Work under subsequent phase(s), if any, will depend on the results and <br />recommendations from the initial two phases and decisions by the City. Subsequent <br />phase work could involve Aspect's support for additional technical investigations, <br />coordination with the County FCZD and their consultant regarding final flood map <br />revisions, additional meetings with the City and/or FCZD, etc. <br />Reecer Creek Floodplain Mapping and Levee Certification Support - Scope of Work Page 11 <br />
