Hungary Creek Stream Restoration

Project Summary

The County of Henrico identified a need for sediment load reduction to Hoehns Lake. High erosion rates were attributing to an unsightly amount of sediment being deposited into the lake and adjacent homeowners asked the county for a solution.

This project included the preparation of complete design plans and specifications for the restoration of approximately 1,600 linear feet of stream channel. The project extended from approximately 500 feet downstream of the existing lake near the West End Manor Civic Association to approximately 850 feet upstream of Hoehns Lake.

The County also tasked Timmons Group with estimating the removal rates of nitrogen, phosphorous, and sediment based on the upcoming regulations for nutrient load reduction.

Timmons Group resultantly estimated that total nitrogen would be reduced by 861 pounds per year, total phosphorus would be reduced by 64 pounds per year, and that the total amount of sediment would be reduced by 121,000 pounds per year.

Through Timmons Group’s On-call contract, we continue to design Henrico County’s stream projects including Belmont (,700 lf) and Dunncroft (2,240 lf); both due to go to construction in 2017.
