EXHIBIT 1 CITY OF SAN MARCOS BLANCO GARDENS DRAINAGE IMPROVEMENT PROJECT CHANGE IN SERVICES FOR ADDITIONAL CONSTRUCTION PHASE SERVICES SCOPE OF SERVICES sorted, removing all live and dead shell material. The minimum number of samples requested is based on the rate of 1 quadrat per 5 m2 of delineated area of the cells that met the above triggers. A minimum of 50 quadrat samples shall be collected regardless of size of the area within the Salvage Zone that met the above triggers. Phase II quantitative survey results will be utilized to arrive at anticipated take of mussel species for the project. C. Salvage Event for Listed Mussel Species (if needed): If state or federally listed mussel species are located during the Phase I or Phase II effort, CMEC will perform the salvage and relocation of mussels from the salvage area of the proposed project. A multiple pass depletion effort, with a minimum of two passes, shall be made through each cell until less than 10 percent of the original number of live common mussels collected are recovered on the final pass. If a listed species is found during the final pass of a cell or transect, an additional pass will be completed in that cell or transect regardless of the percentage threshold achieved during that pass. Additional passes will only be requested in cells or transects that have not reached the necessary threshold or where listed species were collected. Other cells that have met the threshold will require no further effort. All collected mussels will be relocated. Following completion of salvage effort, CMEC will prepare a draft and final survey report summarizing the results of the survey and relocations. D. Survey and Relocation Draft and Final Report: CMEC will prepare reports detailing the mussel survey and relocation efforts. Reporting criteria will be consistent with the ARRP and the current TPWD guidance. E. Salvage Event for Aquatic Species (Excluding Mussels): After completion of Task land installation of the cofferdam, relocations methods for freshwater aquatic species will be completed for the remainder of the project area as specified by the TPWD Kills and Spills Team during the application process and outlined in the approved ARRP. CMEC will perform the relocation effort before and during the dewatering process. Once the water depth reaches approximately 24 inches relocation of aquatic resources will begin by dip netting, seining, and collection by hand. Species will be relocated as described in the ARRP. CMEC assumes that no more than two mobilizations (i.e., two separate days of draw -down operations) would be required. In the event that the cofferdam is overtopped by flood water or is otherwise breached, any additional environmental services required by TPWD, USACE, or the USFWS may require an additional scope and fee agreement. Following completion of the relocation effort, CMEC will prepare a draft and final survey report summarizing the results of the survey and relocations. The report will include graphics showing the extent of the areas surveyed and the relocation area, a table showing the number of live individuals of each species gathered in the survey area, and representative photographs of each species encountered. CMEC will perform these efforts under the authority of Texas Parks and Wildlife Department (TPWD) Scientific Research Permit SPR -0691-409. CMEC will be responsible for collecting, temporarily holding, and relocating native fishes, freshwater mussels (Unionidae), aquatic reptiles, and amphibians. F. Incidental Aqency Coordination: CMEC understands that TPWD, USACE, and USFWS will require notification and reporting on all facets of the project's construction -phase services. Given that the project has already encountered unforeseen changes in level of effort related to regulatory requests and changing K
