The Kuykendahl Stormwater Detention project is one of two regional stormwater detention basinsFlood Control District is constructing that will reduce flooding risks and damages in portions of the Greens Bayou watershed in north Harris County. The basins are part of a suite of new flood damage reduction projects in the watershed known as Progress Greens.
The Kuykendahl Basin construction project will remove approximately 3.61 million cubic yards of soil from the site, and when completed, is designed to hold approximately 2,325 acre-feet, or 757.6 million gallons of stormwater. Following construction, the basin design calls for 22.19 acres of native tree and shrub plantings, 12.79 acres of stormwater quality treatment wetlands, and 14.04 acres of other created wetlands to replace those impacted by construction.
An existing channel running through the site, formally identified as HCFCD Unit P245-00-00, will be enhanced and stabilized with natural stable channel design features. These include a bankfull bench or gently sloping terrace at the top of the bank to prevent erosion, riffles and cross-vanes constructed of rocks that are specially placed to slow the water flow, and native woody streamside or riparian vegetation to stabilize the banks, shade the water, and create habitat for birds and other creatures.
