Z100-00-00-X285 - Cypress Creek Watershed

Z100-00-00-X285 is a collection of major maintenance projects that will repair various types of channel failures along 5 different project areas within the Cypress Creek watershed. Portions of the identified channels are considered to be in serious failure and these repairs are necessary to prevent further impact to the channels.

Projects included as part of Z100-00-00-X285 are NOT classified as flood damage reduction projects; however, the channel may be widened in some locations in order to restore the channel conveyance capacity back to how the channel was originally designed.

Projects that fall under Z100-00-00-X285 include:

  • K124-00-00-X042 - consists of the removal and disposal of concrete rubble, excavation and disposal of accumulated sediment, erosion repair of approximately 375 linear feet along both channel banks, placement of imported fill, placement of granular fill, installation of riprap, excavation and re-grading of onsite material, and installation of backslope drainage swales and backslope interceptor structures beginning approximately 1100 linear feet and ending 425 linear feet upstream of Louetta Rd; erosion repair of approximately 100 linear feet along the south channel bank, placement of imported fill, placement of granular fill, and installation of riprap and the removal and replacement of an existing pipe outfall, beginning approximately 100 feet downstream and ending 260 feet downstream of Louetta Rd, and Turf Establishment of all disturbed areas; erosion repair of approximately 300 linear feet along both banks of K142-00-00 and approximately 150 linear feet along the west bank of K142-02-00 at the confluence of the channels. The work consists of re-grading of existing materials, and installation of riprap, beginning approximately 500 feet downstream and ending 800 feet downstream of Louetta Rd along K124-02-00, and Turf Establishment of all disturbed areas; erosion repair of approximately 400 linear feet along both banks of K142-00-00 and consists of re-grading of existing materials, and installation of riprap, beginning approximately 1,400 feet upstream and ending 700 feet upstream of Mirror Lake Dr., and Turf Establishment of all disturbed areas; a spot repair of a washout behind the existing concrete lining of K124-00-00 using flowable fill to fill the void, located approximately 100 feet upstream of Mirror Lake Dr., and Turf Establishment of all disturbed areas; erosion repair of approximately 600 linear feet along the north and south channel banks, placement of imported fill, placement of granular fill, and installation of riprap, between Mirror Lake Dr and Candle Creek Drive, and Turf Establishment of all disturbed areas; erosion repair of approximately 20 linear feet along the north channel bank, re-grading of existing materials, installation of backslope interceptor swales, the installation of a new backslope interceptor structure, and installation of riprap, located approximately 550 linear feet upstream of Haude Rd, and Turf Establishment of all disturbed areas.
  • K124-00-00-X036 - consists of removal of concrete rubble, excavation and disposal of natural soils, re-grading of existing on-site materials, installation of backslope swales, installation of backslope interceptor structures, installation of riprap, installation and maintenance of SWPPP items, beginning approximately 250 linear feet downstream and ending 1,850 linear feet downstream of Cypresswood Dr, and Turf Establishment of all disturbed areas. 
  • K124-02-03-X001 - consists of approximately 45 feet of erosion repair, installation of riprap at a pipe outfall approximately 250 feet upstream of Meadow Hill Dr, and removal and disposal of broken concrete slope paving, placement of cement stabilized sand, placement of new concrete slope paving, installation of riprap and the removal and replacement of Metal Beam Guard Fence at the upstream and downstream faces of the Meadow Hill Dr. culvert, and Turf Establishment of all disturbed areas.
  • K124-00-00-X043 - consists of the removal a concrete low water crossing, erosion repair of approximately 150 linear feet along both banks of the channel with imported fill, placement of granular fill and installation of riprap approximately 200 linear feet downstream of Rhodes Rd. The second consists of the removal and disposal of existing concrete slope paving, removal and disposal of concrete rubble, excavation and disposal of accumulated sediment, erosion repair of approximately 400 linear feet along the east/north channel bank, placement of imported fill, placement of granular fill, excavation and re-grading of onsite material beginning approximately 1,900 linear feet and ending 1,500 linear feet upstream of Louetta Rd.
  • K127-00-00-X014 - consists of spot repairs of washouts behind the existing concrete lining of K127-00-00 using flowable fill to fill the voids, located approximately 1,150 and 1,250 linear feet upstream of Cypress Springs Dr, along the north bank of the channel, and Turf Establishment of all disturbed areas.

The total cost for these channel repairs is expected to be approximately $5.8M and will be funded using grants from the Natural Resources Conservation Service and Federal Emergency Management Agency.

There will be heavy machinery near project sites and substantial vegetation removal operations may be needed in order to properly prepare the site for construction.For public safety reasons, trail users can expect intermittent closures as the projects progress. Please pay attention to posted signage in the project areas.

Construction has already begun at some of the project sites, but anticipated completion for all sites is Fall 2020 depending on weather.
