Dear Carlos,
Dost Engineering, Inc. is pleased to submit this proposal to provide professional civil engineering services in support of the City of Lake Elsinore’s SB-821 Spring Street Sidewalk Project. The project includes new ADA-compliant sidewalks and related improvements along Spring Street, between Lakeshore Drive and Limited Avenue.
Topographic and utility surveying services will be provided by Guida, Inc., who will serve as a subconsultant to Dost Engineering for this project.
Please find the following exhibits enclosed with this proposal:

2 EXHIBIT A – PROJECT UNDERSTANDING
The proposed project involves the design and construction of approximately 1,500 linear feet of ADA-compliant sidewalk along Spring Street, between Limited Avenue and Lakeshore Drive.
Planned improvements include new curb and gutter, curb ramps, driveways, retaining walls, and other supporting infrastructure.
The project corridor presents several design challenges, including steep grade changes, multiple driveway tie-ins, existing retaining walls, and proximity to private homes. To meet ADA standards and maintain property access, careful grading transitions, utility coordination, and potential wall removals will be required.
A detailed topographic and utility survey will be essential to guide design decisions and identify potential conflicts. Coordination with adjacent property owners will also be needed to facilitate survey access and ensure constructible grading transitions.
Dost Engineering will lead the civil design effort as the prime consultant, supported by Guida, Inc., who will provide the topographic and utility surveying services.
3 EXHIBIT B – SCOPE OF SERVICES
The project will be delivered through a coordinated effort between Guida, Inc. (surveying subconsultant) and Dost Engineering (prime consultant). The scope is structured in two primary phases: (1) topographic and utility survey, and (2) civil design and construction support services.
Guida, Inc. – Surveying Subconsultant
Guida, Inc. will initiate the project by performing a detailed topographic and utility survey of the Spring Street corridor. This will include establishing GPS-based horizontal and vertical control tied to NAVD88, field mapping of all visible surface features (e.g., curbs, sidewalks, driveways, retaining walls, trees, signage, mailboxes, and utility structures), and opening manholes to document invert elevations, pipe sizes, and flow direction. Utility research will be conducted using Dig Alert and through direct coordination with service providers.
Survey data will be compiled into a comprehensive AutoCAD Civil 3D base map at 20-scale, including a digital terrain model (DTM), which will serve as the foundation for subsequent design.
A detailed description of Guida’s services, assumptions, and exclusions is provided in Attachment 1 – Guida Proposal, incorporated herein by reference.
Survey Deliverables:
Civil 3D CAD base file with topographic and utility data Signed PDF of topographic survey sheet
Field notes (PDF format)
Field photos (JPG format)
Note: Civil design efforts will commence upon receipt and review of Guida’s full survey deliverables.
Dost Engineering – Civil Design and Project Management
