Mr. Tom Smilh <br />July 3/, 20I3 <br />Page 2 of 3 <br />b. The flood routing analysis will take into account the four small ponds immediately <br />downstream of Droz Creek Dam, and the possible domino failure effect of breaching <br />Droz Creek dam. <br />c. The final study reach for this project will be determined during modeling. The anticipated <br />downstream limit of the study is at a point downstream on the Arkansas River from the <br />City of Poncha Sprin�s where the flood impacts are negligible. <br />4. Inundation Mappmg �� J � T <br />a. Flood extents will be mapped within FLO-2D and then exported to GIS. The base map <br />will consist of 2011 aerial imagery obtained from the National Agricultural Imagery <br />Program (NAIP). <br />b. Identify peak discharge, peak flood wave amval times, peak velocities, and peak flood <br />depth at critical locations for each analysis phase. <br />c. Annotate roads, highways, and critical infrastructure near the impacted reach and call out <br />all roads that are expected to be overtopped by the dam breach flood for each analysis <br />phase. <br />5. Emergency Action Pian <br />a. An Emergency Action Plan will be developed using SEO templates and include the <br />inundation mapping. <br />DELIVERABLES AND SCHEDULE <br />The results of the analysis will be documented in an inundation mapping report. A preliminary <br />inundation mapping report will be provided to the DWR for review. Once comments from the DWR <br />are addressed, the final inundation mapping report and Emergency Action Plan will be provided <br />along with printed copies of the inundation maps for each phase of the analysis. In addition, CDs will <br />be provided which will contain shapefiles of the inundation limits, PDFs of the inundation maps, <br />supporting spreadsheets, and copies of all models used in the analysis. <br />We expect that the final deliverables to be delivered six weeks following a signed scope of work. A <br />preliminary report will be submitted to the DWR, and all comments from the DWR will be addressed <br />in a timely fashion so that the project is complete by the due date. <br />Lindsay George will serve as the Project Manager for this project with support by Clay Good in order <br />to complete the identified tasks. Mike Applegate will serve as a senior technical advisor for project <br />review and quality control. <br />BUDGET <br />We propose to complete the above scope of services on a time and materials basis with an estimated <br />budget not to exceed $15,800. A grant application will be submitted to the DWR to cover 50% of <br />these costs, with a resulting cost to you not to exceed $7,900. We will bill you the full amount and <br />the DWR will reimburse you for 50% of the total. We propose to bill this amount in a single invoice <br />once the DWR has granted approval of the breach analysis reports and inundation maps. <br />PROFESSIONAL SERVICES AGREEMENT <br />If this scope of services is acceptable, please sign below and return a copy to us. We will execute a <br />Master Services Agreement and a work order based on this scope of services. Following our receipt <br />ofthe documents, we wiil begin work on the project. <br />4 � � <br />
