Report
Summary
The purpose of this project is to implement comprehensive flood management solutions across multiple project sites within the Laveen area. The program involves the design and construction of new storm drain systems, detention basins, and high-capacity inlets.
The Laveen Area Drainage Program is guided by the findings of the 2017 Laveen Area Drainage Master Study/Plan Update and the 2022 Laveen Area Drainage Feasibility Study. These studies provide updated hydrologic and hydraulic modeling, identify flood-prone areas, and outline both regional and neighborhood-scale drainage improvements within the Laveen watershed. As part of this effort, the Consultant will review the relevant portions of these studies to validate existing assumptions and confirm how recommended conveyance, basin, and storm drain improvements apply to project locations. This review ensures that the planned designs reflect current conditions and align with the broader, long-term drainage strategy for the Laveen area.
Typsa, Inc.'s services include, but are not limited to: conduct detailed site investigations, including topographic surveys, geotechnical analysis, hydrological studies, and hydraulic studies; assess existing drainage conditions and identify areas prone to flooding; review the Laveen Area Drainage Master Study and the City of Phoenix Laveen Area Drainage Feasibility Study as they relate to these specific locations to validate or update findings based on existing site conditions; develop preliminary design concepts and alternatives for flood management; prepare detailed engineering designs for storm drain systems, detention basins, and related infrastructure; develop construction plans, specifications, and cost estimates; provide design submittals and drainage reports at the 30 percent, 60 percent, 90 percent, and 100 percent completion stages, followed by a sealed final submittal; coordinate with relevant stakeholders, including City departments, utilities, and the public, to ensure comprehensive design solutions; secure necessary permits and approvals from regulatory agencies; identify necessary right-of-way and easement requirements for project implementation; prepare supporting documents such as legal description, easement, area calculations and map exhibit; develop and implement a public outreach plan to inform and engage the community about the project; organize public meetings, workshops, and informational sessions to gather feedback and address concerns; provide regular updates to the public and maintain open lines of communication throughout the project duration; assist with the procurement of a construction contractor; review and respond to Requests for Information during construction; perform shop drawing reviews and approvals; provide general administration and attend construction meetings as needed; provide on-site construction inspection and administration services to ensure compliance with design specifications and standards; monitor construction progress, quality, and safety; review contractor submittals and provide recommendations to the City regarding change orders and payment requests, and conduct final inspections and prepare punch lists to ensure project completion.
