Exhibit A Scope of Work <br />REECER CREEK FLOODPLAIN MAPPING AND LEVEE <br />CERTIFICATION SUPPORT SERVICES <br />Scope of Work <br />Aspect Consulting LLC, February 4th, 2020 <br />Background <br />Aspect Consulting, LLC (Aspect) has been selected by the City of Ellensburg to provide <br />support services related to floodplain mapping and the potential certification of set -back levees <br />along Reecer Creek. The Kittitas County Flood Control Zone District (FCZD) is completing a <br />flood mapping project that includes lower Reecer Creek. The County's flood model does not <br />currently include floodplain changes north of Dolarway Road that are being designed by the <br />City, specifically a set -back levee, bridge, and network of floodplain swales. It is important for <br />the 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 <br />existing and planned levees will be included in the FCZD's flood model and whether they will <br />be formally recognized by FEMA and the National Flood Insurance Program (NFIP) as <br />providing protection during a 900 -year flood to lands outside the levees. City coordination with <br />the FCZD and FEMA along with a systematic review of the levee standards, elevations, and <br />tie-in locations is needed to identify and quantify changes that may be needed to meet current <br />levee certification standards. <br />Phased Support Services <br />Aspect recommends a phased approach for the floodplain mapping and levee certification <br />support services: <br />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 will <br />also involve providing levee, bridge, and floodplain swale design information to the FCZD <br />and interactions with the FCZD and their consultant regarding updated flood modeling <br />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 standards <br />and final determination of design changes to the existing and planned levees and related <br />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 Suppo, - SGope o:' Work Page 11 <br />
