Noteworthy Activities

  • Facilitated annexation, developers’ agreements and zoning through the Town of Prosper. Developed planned development regulations for the master plan.
  • Developed standards for street trees that allowed for implementation of this design element for the first time in Prosper.
  • Developed a land management plan required to decommission the then existing Concentrated Animal Feeding Operation (CAFO) known as Mahard Egg Farm. Worked with a team to get permit approval through various state and federal agencies.
  • Facilitated the sewer service agreement between the Town and Upper Trinity Regional Water District which provides for sewer service to the west side of Prosper, including Windsong.
  • Provided full engineering and surveying services required to construct the Westside Utilities Project – including 25,000 LF of large diameter water line and 15,000 LF of large diameter sanitary sewer line – that opened up development of the town west of the Dallas North Tollway. This project included permitting through the BNSF railroad, the North Texas Tollway Authority and TxDOT.
  • Assisted with formation of the Windsong Ranch Municipal Management District.
  • Provided civil engineering and surveying services for every phase of residential development to date, including boundary and topographic surveys; cost estimates; platting; engineering design; construction administration; and construction staking.
  • Received approval for an Individual Permit from the USACE for the entire master plan; worked with IES to minimize impacts and to develop a mitigation plan.
  • Prepared flood study for the Doe Branch basin that demonstrated detention for the western portions of Prosper was not required. This resulted in the town waiving detention requirements for the basin and an ILA between Prosper and Little Elm to this end.
  • Worked with CS to provide topographic survey data and exhibits required to successfully process numerous LOMRs.
  • Funding was provided through a developer’s agreement between the Town, the EDC and various landowners.
