Attachment A SCOPE OF SERVICES CITY OF SAN MARCOS PROPOSED SESSOM CREEK WASTEWATER CAPACITY IMPROVEMENTS PRELIMINARY DESIGN, DESIGN, BID, AND CONSTRUCTION PHASE the background research for the study, CoxJMcLain personnel will conduct a database search of the THC Sites Atlas to identify previously documented archaeological sites as well as historic resources such as historic landmarks, cemeteries, markers, and structures listed on the National Register of Historic Places (NRHP) or as State Archaeological Landmarks (SALs). The results of the search will be used in conjunction with pipeline design and routing information and published data regarding soils, topography, geology, etc. to evaluate the probability of the project encountering recorded and /or unrecorded resources. b. Permit Evaluation: Identify Local, State, and Federal permits required for each proposed route and estimate acquisition time for each permit. c. Hazardous Materials Database Search: CoxJMcLain shall obtain a database search for the project corridor in accordance with all appropriate inquiries standards under American Society for Testing and Materials (ASTM). Results of the database search will be confirmed during field investigations. Should findings in Phase A indicate the presence of a hazardous material site(s) that may pose a risk to project development, a Phase I Environmental Site Assessment will be recommended and could be added for an additional scope and fee. d. Preliminary Geologic Assessment: Raba - Kistner, Inc. will conduct a geologic assessment consisting of site reconnaissance from existing right -of -way, geologic literature review, and a review of nearby boring data to determine general geologic conditions and suitability of proposed construction methods. e. Vertical Constraints and System Integration: The proposed relief main must be integrated with the existing system, including the upstream and downstream connection points, and any intermediate collection lines that connect to the existing line. KFA will perform a system integration evaluation, including an assessment of existing storm sewer interference, particularly the existing storm sewer in University, and update the existing spreadsheet model of the line. Where possible the proposed wastewater line will be kept to a maximum installed depth of 15 -feet. f. Workspace and Easement Evaluation: Identify and map necessary workspace and easements required for construction, maintenance, and operation for each proposed route. Estimate street right -of -way impacted and degree of impact. g. Develop Class C (± 25 %) estimates of probable construction based on the information gathered above. 6. Prepare 30% plan and profile sheets of the preferred route, showing property ownership, existing right -of -way, wastewater line location, and proposed permanent and temporary construction easements. Sheets shall be aerial based and be at a scale of 1" = 100'. 0FRIESE Page 3 of 10 e
