Clean Water Projects
The Clean Water Program develops new stormwater facilities and designs and implements updates to older facilities that collect and treat polluted storm runoff. These projects control stormwater flows and help:
- Reduce pollution in our water runoff.
- Improve water quality treatment.
- Reduce stream erosion and protect river habitat.
- Keep our waterways safe for recreation and other uses.
Projects vary in scope and size, but may include installing rain gardens or wetlands for improved water quality treatment, expanding water storage, modifying inlets and outlets, and repairing or replacing aging facilities. Projects are funded by clean water fees and state and federal grants.
Whipple Creek Watershed Management Plan - In 2015 and 2016, Clark County will conduct a watershed-scale assessment of the Whipple Creek watershed. This plan is a requirement of the county's NPDES Phase I Municipal Stormwater Permit (S5.C.5.c - page 20 of the permit). More>>
2017 - Capital project schedule (as proposed):
2016 - 2019 Urban Tree Canopy Restoration Program
Restoring urban tree canopy cover in the neighborhoods that drain to Cougar, Suds and Salmon Creek (Salmon Creek and Felida area). Clark County is partnering with Friends of Trees to implement a Lower Columbia Fish Recovery Board Clark County Clean Water Fund grant that will plant shade trees in public rights-of-ways in neighborhoods that are lacking street trees. The project will engage volunteer crew leaders, neighborhood coordinators, summer inspectors, planters and homeowners in training and planting events. Outreach with participants will occur during all phases of the projects about the importance of trees in the urban watershed. More>>
2016 - 2018 Downspout Disconnect Program
The Downspout Disconnect program will provide financial incentives and technical assistance to homeowners to disconnect existing roof downspouts from the County's municipal separate storm sewer system. Disconnects will be directed to areas on the homeowner's property where the water can infiltrate (soak into the ground) as appropriate for each individual site. Clark County is partnering with the Clark County Conservation District to implement the grant from the Lower Columbia Fish Recovery Board's Clark County Clean Water Fund. More >>
