Eau Gallie Blvd. Suite 232 Melbourne, FL 32934 Project No. BWM002 RE: IRC West Wabasso Septic to Sewer Phase 3 (The "Project") Proposal to Provide Surveying Services (The "Proposal") Dear Mr. Flavell, Infrastructure Solution Services (ISS) is pleased to provide this proposal for surveying services for the Indian River County West Wabasso Septic to Sewer Project Phase 3, in Wabasso Florida, for Bowman Consulting Group (BCG). Section I. BACKGROUND After speaking with Mr. Eric Flavell (BCG) and reviewing the provided scope and limits, it is our understanding that the project consists of a topographic route survey of approximately 1,400' of residential roads and 200' of a main road, that includes approximately 700' of 59th Avenue, 700' of 58th Court and 200' of 581h Avenue to be used as basis of design of a gravity sewer system with a lift station that is to be tied into an existing sanitary force main. All roads will be surveyed from right of way to right of way line with the addition of any pertinent data on each lot that will help with design. It is our understanding that the project will include establishing all right of way lines and approximate lot lines per plat and property appraiser information to be utilized for the purpose of designing a gravity sewer system and lift station. The ISS team will coordinate the location of all accessible existing septic tanks and cleanouts for the 14 homes that will be connected to the new system. 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. In addition to the location of the permanent features, any major semi-permanent features which may exist will be located. The survey will also include a full topo of the vacant lot at address 8475 on the east side of 58th Court and 20' platted alley on the Plat of Hillside Subdivision. The location of any underground utilities, that are marked by others, will be collected within the project area. Trees of all species and size along the south side of the project shall be collected. Mr. Flavell (BCG) has requested a high resolution, georeferenced drone image to be used as a background in the survey. Section II.
