DOUCET A Kleinfelder Company August 1, 2023 October 13, 2023 (revised) Mr. Marcus Naiser, PE Senior Engineer, Capital Improvements City of San Marcos 630 E Hopkins San Marcos,Texas 78666 Email: MNaider@sanmarcostx.gov Re: Proposal for Professional Engineering Services Rio Vista Localized Drainage Improvements Surveying, Final Design thru Bid Services San Marcos,Texas Doucet Project P415-009-04 Dear Mr. Naiser, Doucet&Associates, Inc. ("Doucet") is pleased to submit this proposal for surveying and engineering services for the above referenced project. Doucet recently submitted 60% design drawings to the City of San Marcos under an existing contracted scope of work. Doucet met with City staff to review the submittal and received comments and direction on a path moving forward for permitting and construction. This proposal for civil engineering and surveying services is to assist the city in finalizing design and permitting so the project can be bid for construction. After review of this proposal, please let us know if you have any comments. If acceptable, please sign and return an executed copy to serve as our authorization to proceed. The following outlines our proposed scope of work: Task 1—Surveying Based on review and discussion of the 60%design documents, it was decided that an accurate depiction of property boundaries and the Union Pacific Rail Line right-of-way along Riviera Drive is necessary. This is to hopefully avoid licensing of utility improvements within Union Pacific right-of-way. Additionally, accurate depiction of the rear property and easement boundaries along the lots in which drainage improvements are necessary to place property fences back where they belong and to establish easements as needed. 1. Doucet will perform right-of-way boundary survey along Riviera Drive adjacent to the Union Pacific Railroad. Doucet will update existing design-level topographic surveys to field locate found visible features, both horizontally and vertically, including but not limited to existing on-site structures, buildings, structures, drainage features, adjacent and onsite sidewalks, curb lines, pavement, and visible above-ground utility appurtenances to facilitate engineering design at areas of pavement, utility and drainage tie-ins as identified by the project engineer. Doucet will contact Texas 811 for utility locations, markings placed by purveyors will be surveyed at time of design survey. PAGE 13 rio vista proposal 90 through CA 20231012.docx October 13,2023
