Description
The Work consists of restoration of an unnamed tributary to Upham Brook within Three Lakes Park in Henrico County, Virginia. The project section consists of approximately 1,520 linear feet of perennial stream channel, begins downstream of the newly constructed Lake Overton dam spillway, crosses below Sausiluta Drive, and discharges into the easternmost lake within the park. The proposed restoration shall utilize a Priority 2 approach. Priority 2 restoration involves constructing a new bankfull channel within a newly excavated lower floodplain bench. This stream is designed as a low sinuosity C3/C3b type channel. Wood and rock structures are specified for grade control and protection of vulnerable banks. Plantings of native vegetation will help stabilize banks and improve the riparian buffer. All denuded areas shall be re-seeded, fertilized, matted, and planted with native woody stems and herbaceous cover. Large growth trees shall be protected to the greatest extent practicable, allowing for increased seed dispersal and shade canopy for the newly planted seedlings. The project construction shall comply with conditions of the 2024 General VPDES Permit for Discharges of Stormwater from Construction Activities.
