Eau Gallie Blvd., Suite 232 Melbourne, FL 32934 *INFRASTRUCTURE SOLUTION SERVICES '7175 Murrell Road, Melbourne, FL 32940 Phone: 321-622-4646 Subject: Proposal to Provide Surveying Services Project No. BCGO05 — Indian River County West Wabasso Septic to Sewer Phase 3C Dear Mr. Flavell: Infrastructure Solution Services (ISS) is pleased to provide this proposal for surveying services for the Indian River County (IRC) West Wabasso Septic to Sewer Project Phase 3C (the "Project") in Wabasso, Florida to Bowman Consulting Group (BCG). SECTION I. BACKGROUND After speaking with Mr. Eric Flavell (BCG) and reviewing the provided scope and limits, it is ISS's understanding that the Project consists of a topographic route survey of approximately 2,500' of residential (dirt) road, 1,200' of residential (paved) road, and 400' of a main road. The project will be divided into two separate tasks. Task 1 will include approximately 700' of 87th Street (dirt), 400' of 86th Street (dirt), and 1,400' of 63rd Avenue (dirt). It will include the connection of 13± homes. The survey will be used to aid in the design of a gravity sewer system that will flow to an existing sanitary lift station on 87th Street. It is ISS's understanding that the project will include collecting all available property control on all property frontage to help establish approximate lot lines (per IRC Property Appraiser information) to be utilized in design of the gravity system and tying into the lift station. The survey will also include a detailed location of the existing lift station with pipe sizes, invert, and bottom elevations. Task 2 will include 1,200' of 61st Street (paved), 400' of 85th Street (SR 510), topo, and locations of a 100' X 100' section of parcel 39232 in the SW comer (per IRC Property Appraiser). It will include connection to 14 homes. This survey will be supplemental to the survey previously done by IRC and will not include collecting any property control along the route. For both Tasks, The ISS team will coordinate the location of all accessible existing septic tanks and cleanouts for the 27± homes that will be connected to the new systems. All finished floor elevations will be established for said homes as accurately as possible for the purpose of calculating slope on gravity laterals along with general grade of the lot. All house basic footprints and permanent features will be collected and shown to aid in design of service connections. The location of underground utilities, that are marked by others, will be collected within the project area. A high resolution, georeferenced drone image will be provided as a background in the survey. �,
