The City of Caldwell intends to approximately double the width of Ustick Road and right-of-way, allowing for five lanes of vehicular traffic. This project will encroach into, and modify the FEMA floodway. Therefore, the City is required to obtain a hydraulic & hydrologic analysis to determine the base flood elevations within the extent of the affected parcels. We request that Caldwell Urban Renewal Agency (URA) approve the agreement, by allowing the City Engineer to sign and execute the Task Order "Hydraulic Modeling for Indian Creek at Ustick Road" between Bowen Collins & Associates and the City of Caldwell in the amount of $23,240. RECOMMENDED ACTION: We recommend that the URA approve the agreement and allow the City Engineer to sign and execute the above-mentioned Task Order for "Hydraulic Modeling for Indian Creek at Ustick Road."

Title Principal 6BOWEN COLLINS 776 EAST RIVERSIDE DRIVE, SURE 250 • EAGLE, IDAHO 83616 TEL: 208.939.9561 • FAX: 208.939.9571 May 6, 2020 Ashley Newbry, P.E. City of Caldwell 621 Cleveland Blvd. Caldwell, Idaho 83605 Subject: Proposal for Flood Modeling - Indian Creek at Ustick Road Dear Ashley The City of Caldwell (City) will be widening Ustick Road east of Cleveland Blvd in the near future. As part of this project, the City would like to design a replacement for the existing corrugated metal arch culvert on Indian Creek at Ustick Road. Published FEMA National Flood insurance maps and the accompanying Flood Insurance Study indicate that the existing culvert restriction at this location presents a significant potential for Flooding of areas upstream of the culvert on Indian Creek. The City desires to retain Bowen, Collins & Associates (BC&A) to provide survey and hydraulic modeling support services associated with the design of the new bridge or culvert. The purpose of this letter is to summarize our proposed scope of services and fee for this work. 1. Collect and Review Existing information: BC&A will collect and review available information for the existing culvert and Indian Creek, including the published FEMA floodplain mapping and Flood Insurance Study (most of which we have already obtained). This includes the FEMA hydraulic computer model for Indian Creek. We will conduct a site visit with City staff to observe field conditions and gather information. We will also obtain a plat map for the area from the City or from Canyon County. 2. Field Survey: BC&A will work with Idaho Survey Group to survey a section of Indian Creek with a length of approximately 1600 feet (i.e. approximately 800 feet upstream and downstream of the existing Ustick Road culvert). The survey will Include detailed survey of the road right-of-way at the crossing. The survey will include up to 15 cross sections along Indian Creek. The purpose of the survey is to provide supporting information for updated modeling of Indian Creek and sizing of a new culvert that will be designed by the City. 3. Hydraulic Modeling: BC&A will use the Indian Creek FEMA hydraulic model and the published hydrology to evaluate and model alternatives for replacement of the existing culvert. Survey information will be used to refine the model as needed. Hydraulic modeling for the Indian Creek will be done using GeoHEC-RAS and HEC -RAS in compliance with FEMA guidelines. We will also work with the City to Identify and model a proposed channel realignment channel realignment for approximately 150 feet of channel south (i.e. upstream) of Ustick Road. 4. Culvert Sizing Recommendation and No -Rise Certification: We will use the hydraulic model to evaluate replacement options and recommend a preferred culvert size for design. We will also complete a no -rise analysis using the hydraulic model. We have assumed that the channel and culvert Improvements will Increase the capacity of Indian Creek and that the Ashley Newbry, P.B. May 6, 2020 Page 2 improvements will not increase the 100 -year water surface. We will prepare a technical memorandum summarizing the modeling analysis and results, recommended culvert size, and documentation (including the required tables and figures) for a no -rise certificate. S. Prepare and Submit FEMA Documentation (LOMR): It Is our understanding that the City would like to prepare and submit a LOMR to revise FEMA Floodplain elevations and extents upstream of Ustick Road once the new bridge has been constructed. For the purposes of this proposal we have assumed this will be handled as a separate task order following construction, and is not included in the scope of services for design support. Based on our understanding of the City's objectives, we propose to complete these tasks on a cost - reimbursable basis with a fee not to exceed $23,240. We can complete the work within 6 weeks of receiving notice to proceed. If you have any questions or need any further information, please call Sincerely, Bowen Collins & Associates, Inc.
