Project Number: 2012-5
Project Phase: Construction
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 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.

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 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 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 Number: 2020-1
Project Phase: Design
Identified Problem: Runoff from the north and west flows through the backyard and collects south of the house. These areas upstream do not have curbs or drainage systems to control the flow of water.
Proposed Solution: Install curb on Clayton Road to direct runoff toward a new curb inlet, and connect the new curb inlet into an existing structure to the east. Install a new vegetated swale to carry flow east to the existing grate inlet at N. Ballas Road.
