EXHIBIT A <br />PROFESSIONAL SERVICES AGREEMENT BETWEEN THE CITY OF SAN <br />MARCOS AND FREESE AND NICHOLS, INC. <br />ENGINEERING SCOPE OF SERVICES FOR <br />MAIN LIFT STATION FORCE MAIN AND RECLAIMED WATER IMPROVEMENTS <br />PROJECT DESCRIPTION: The objectives of this project include an analysis to determine the most cost effective <br />plan for a phased expansion of the Main Lift Station (including verification of the force main sizing), preparation of a <br />conceptual layout illustrating the phased expansion plan for the Main Lift Station, and the design and preparation <br />of plans, bid documents, general /supplementary conditions, technical specifications, and other related <br />documents (Contract Documents) for the installation of: <br />• Two ±3,800 linear feet (LF) force main pipes (parallel), <br />• removal of an existing 20 -inch force main, <br />0 a reclaimed water bulk refilling station located near the Wastewater Treatment Plant (WWTP), and <br />• ±1,000 (LF) of 12 -inch reclaimed water main from the bulk refilling station to Cape Road. <br />SUBCONSULTANTS: <br />A. Surveyor and S.U.E. —Ford Engineering <br />PROJECTSCOPE /ASSUMPTIONS: <br />A. Expansion Plan for Main Lift Station <br />1. The Wastewater Master Plan (WWMP) identified anticipated flows into the Main Lift Station based <br />on population projections for the years 2020 and 2035. Freese and Nichols, Inc. (FNI) will evaluate <br />the following three (3) options for expanding the capacity of the Lift Station, as provided by the City: <br />a. Expansion of existing Main Lift Station <br />b. Reconstruction /new Main Lift Station <br />c. New lift station that intercepts River Road Wastewater Main and diverts it to the WWTP <br />2. Cost estimates will be determined for each of the options for the City's consideration. <br />All three (3) options will include a conceptual layout, site plan and improvement implementation <br />phasing in accordance with work identified above in Section A. This scope does not include design <br />of the improvements. Conceptual layouts will be provided on available aerial maps. Any survey of <br />the potential lift station sites, with the exception of the survey at the Main Lift Station site, will not <br />be provided in this scope. <br />4. FNI will utilize the Infoworks model developed as part of the City of San Marcos Wastewater Master <br />Plan (WWMP), dated 2014, to confirm the necessary phasing of the Main Lift Station. The approved <br />WWMP proposes that the lift station be expanded from its current capacity of 15 MGD to a firm <br />pumping capacity of 23 MGD by 2020 and a firm pumping capacity of 30 MGD by 2035. <br />The lift station may be expanded or replaced to accommodate future flows. This future expansion or <br />replacement will be taken into consideration in designing the proposed parallel force mains. <br />Page 1 of 13 <br />
