Active Storm Water Projects

Project - Laurel Lakes Estates Pond

  1. Project Information
  2. Construction & Design

Project Number:      2018-7

Project Phase:         Construction

Identified Problem: Deterioration of the spillway is making the dam unsafe, as it is eroding on the downstream side of the dam and the dam provides little to no detention benefit. Also due to years of sedimentation the pond is only a few feet deep that makes wading in the pond dangerous and is a breeding ground for mosquitos.

Proposed Solution: The improvements proposed within the project limits include the removal of the existing concrete dam structure, restoration of the stream, and construction of the four (4) cut stone berms to provide detention and reduce stream discharge rates.

Project - 1120 Westmoor Place

  1. Project Information
  2. Construction & Design

Project Number:      2012-4

Project Phase:         Easement Acquisition (Pending)

Identified Problem: Runoff from Tundra Court and Timmor Court properties contributes to erosion and ponding in rear yards of the houses along Westmoor Place. Existing swales, berms, and private drainage systems need improvements.

Proposed Solution: The upstream erosion can be minimized or eliminated by the installation of a series of reinforced turf swales. Improve grading of existing berms and sumps around inlets will improve the capture of runoff into the storm waters sewers and culverts.

Project - 1839 Woodmark Road

  1. Project Information
  2. Construction & Design

Project Number:      2012-5

Project Phase:         Easement Acquisition (Pending)

Identified Problem: Stream bank erosion may present issues for properties at or adjacent to 1839 and 1855 Woodmark Road.

Proposed Solution: Stabilize reach of stream behind residences at 1839 and 1855 Woodmark Road with a combination of rock grade control structures and planted rock slope, or composite revetment.

Project - Summerhill East

  1. Project Information
  2. Construction & Design

Project Number:      2010-3B

Project Phase:         Design

Identified Problem: Summerhill "East" is the final of a three part project to address drainage and erosion issues in the Summerhill Subdivision. Uncontrolled upstream runoff is contributing to creek bank erosion and slope instability that is threatening trees, fences, power poles, sanitary sewer infrastructure, and a pedestrian bridge to properties located on the east side of Summerhill Lane.

Proposed Solution: A creek bank stabilization and this project may also include green infrastructure elements (rain gardens, bioswales, etc.) and / or detention measures on the affected properties to reduce downstream peak flows and associated water levels during intense rain events.

Project - Essex Point / Sellenriek Middle

  1. Project Information
  2. Construction & Design

Project Number:      2011-4C

Project Phase:         Design

Identified Problem: The peak water flows generated by surrounding areas during and following large rain events are causing erosion and potential flooding in the area of Sellenriek Road and Delvin Drive. In addition, the Essex Point Subdivision retention basin experiences debris and sediment issues from upstream.

Proposed Solution: Due to the size of the watershed four projects were identified to reduce peak flows from individual sub-watersheds. This project includes a new inline storage area to provide reduce peak flows, provide water quality benefits, and collect debris.

Project - Oak Springs Cul-de-Sac

  1. Project Information
  2. Construction & Design

Project Number:      2011-11

Project Phase:         Design

Identified Problem: Runoff ponds at a sag in the Oak Springs Lane cul-de-sac. An unpermitted small private inlet is inadequate to prevent the ponding.

Proposed Solution: Modify an existing curb inlet to increase its efficiency and install a new curb inlet and pipe sewer system to minimize ponding in the gutter.

Project - 1617 Mason Valley Drive

  1. Project Information
  2. Construction & Design

Project Number:      2015-9

Project Phase:         Design

Identified Problem: Water from nearby yards collects at the driveway and side yard at 1617 Mason Valley Road. The area floods often because it has no clear flow path to downstream.

Proposed Solution: Connect the storm sewer system at 1608 Foxleigh Court to the system at Mason Valley Road. Replace the existing private drain at 1617 Mason Valley Road with a new area inlet.

Project - 13211 Thornfield Lane

  1. Project Information
  2. Construction & Design

Project Number:      2016-6

Project Phase:         Design

Identified Problem: The creek bank is eroding along the side yard and backyard of 13211 Thornfield Lane near the east corner of the house. The erosion is active and will eventually pose a threat to the house.

Proposed Solution: The most direct solution is to add grade control, bank toe protection, and bank stabilization along about 100 feet of the creek.
