As discussed on our phone call on June 26, 2023, there are several other areas of the City outside the City's ETJ that were necessary to be included in the current PHWA modeling due to their hydrologic and hydraulic connectivity to critical urban areas inside the City Limits. ® City Limits + ETJ = 637 sq. mi. PHWAArea Modeled = 615 sq. mi. (Original Contract) o Additional PHWAArea = 320 sq. mi.

On the phone call, the City requested additional modeling in areas of the City that are in the undeveloped portions of the ETJ that were swapped out for the hydrologically -connected urban areas already modeled in the May 2023 report. Therefore, Pape -Dawson is requesting additional funds to complete this additional modeling (approximately 320 sq. mi.). Furthermore, on a phone call on August 10, 2023, the City requested additional 1-, 5-, and 100-year depth hazard polygons to remove the mapping related to the trenches for public consumption. This additional mapping deliverable will be in addition to the standard deliverable formats already provided to the City. These services are considered above and beyond previously authorized work and include the following: I. ADDITIONAL PHWA AREA 1-, 5-, AND 100-YR MODELING AND MAPPING [TASK 296] $33,000 Add approximately 320 sq. mi. of PHWA modeling and mapping to the May 2023 citywide PHWA model created by Pape -Dawson for the 1-, 5- and 100-year storm events. The additional 320 sq. mi. will cover the 280 sq. mi. of undeveloped ETJ the City wants modeled: • Append LiDAR and Land Use data for the additional PHWA area. Add breaklines and hydro -rectify the terrain at embankments and crossings using rough measurements of the structures from EagleView. • Check and update boundary conditions. • Combine mapping from multiple model runs into one seamless mapping for the 1-, 5- , and 100-year mapping. Perform cleanup of orphans and isolated polygons. • Prepare combined database of 1-, 5-, and 100-year mapping for citywide PHWA to submit to the City as a deliverable. ADDITIONAL 1-, 5-, AND 100-YR MAPPING OUTPUTS [TASK 2971 $17,000 • Prepare additional 1-. 5-, and 100-year output mapping (without trench mapping) for public consumption. • Deliverables include 1-, 5-, 100-year PHWA polygons, the 100-year Hazard Classification Polygon and raster file, and a 100-year Water Surface Elevation raster without the trench mapping shown in the mapping.

A budget increase of $50.000.00 is the estimated cost of Pape-Dawson's current understanding of the additional services identified above.
