c. Preliminary Hydraulics: LAN will develop hydraulic models to determine preliminary ditch size, <br />material, and alignments as well as the two (2) preliminary cross culvert sizes and locations according <br />to City of San Marcos criteria. Results from the hydraulics will be summarized in the Preliminary <br />Engineering Report. All proposed drainage features will also be included on the 30% roll plot. <br />d. It is not anticipated that a Geotechnical or Structural Analysis will be required for any of the <br />proposed drainage structures. In the event that either is required, it will be considered additional <br />services outside this scope of services. <br />8. Determine Project Permitting /Design Requirements: LAN will determine project permitting and design <br />requirements for local, state and federal entities. During the preliminary design phase, LAN will make <br />every effort to develop a solution to avoid USACE permitting that is required due to disturbance of the <br />"ordinary high water mark" at the project outfall. In the event this is unavoidable, LAN will communicate <br />this early on to the City, and determine appropriate alternatives to avoid project delays. <br />A TCEQ Edwards Aquifer Contributing Zone Protection Plan Application is not anticipated due to the <br />disturbed construction being less than 5 acres, based on the Texas Administrative Code Title 30, Part 1, <br />Chapter 213, Subchapter B rule 213.21. In the event that it is determined that permanent Water Quality <br />BMP's and a TCEQ Water Pollution Abatement Plan (WPAP) are required, it will be considered additional <br />services. <br />9. Identify Utility Providers and Potential Conflicts: LAN will coordinate with the City and subconsultants <br />Byrn & Associates and Cardno to determine existing utility service providers within the project limits, and <br />potential utility relocations required. <br />10. Develop Construction Cost Estimates: Based on the results of the preliminary engineering phase and <br />proposed alignments, LAN will prepare an Opinion of Probable Construction Cost based on 30% design. <br />11. Deliverables: <br />a. Preliminary Engineering Report Draft: LAN will provide 3 hard copies and 1 electronic pdf file of a <br />draft PER to the City for review and distribution. <br />b. Preliminary Engineering Report Final: Upon City review of the draft PER, LAN will address all review <br />comments and provide 3 hard copies, 1 electronic pdf file, and a CAD file of the final PER. The CAD <br />file(s) shall include all exhibits and /or proposed alignments included in the PER. <br />II. Design Phase (60/90/99 % /100 %) <br />1. Project Management and QA /QC: This task includes regular communications with the City; managing <br />subconsultants, staff resources, budgets, and schedules; invoicing; implementing and monitoring of <br />QA /QC efforts; and other activities associated with managing the project. <br />2.
