Z100-00-00-X296 - Barker Reservoir and Addicks Reservoir Watersheds

Z100-00-00-X296 is a collection of major maintenance projects that will repair various types of channel failures along 23 sites within the Barker Reservoir and Addicks Reservoir watersheds. Portions of the identified channels are considered to be in serious failure and these repairs are necessary to prevent further impact to the channels.

In order to restore channel conveyance capacity to its original design, excavation may widen some channel sections beyond their current condition.

Barker Reservoir Watershed Repairs

  • T101-00-00-X054 - consists of major erosion repairs to include the installation of riprap, granular fill, well-graded mix, import fill and removal/replacement of backslope interceptors.  Total length is about 600 linear feet just east of Mason Road.
  • T101-00-00-X055 - consists of major erosion repairs to include the installation of riprap, well-graded mix, import fill and removal/replacement of backslope interceptors. Total length is about 800 linear feet just upstream of Mason Road and 300 linear feet just upstream of Merchant’s Way.
  • T101-00-00-X056 - consists of erosion repairs consist of the installation of riprap, well-graded mix, import fill and removal/replacement of backslope interceptors and related outfall pipes. Segments of the existing hike & bike trails (pavement, retaining walls, handrails) will need to be removed to complete the erosion repairs. Site is approximately 1,000 linear feet from Westgreen Boulevard to Kingsland Boulevard.
  • T101-00-00-X057 - consists of erosion repairs to include the installation of riprap and import fill and removal/replacement of backslope interceptors and related outfall pipes.  Total length of 500 linear feet just downstream of Prince Creek Drive.
  • T101-00-00-X059 - consists of two erosion repairs: one erosion repair to be filled with import fill and one repair at an outfall structure.  The outfall structure will require the removal of existing riprap and installation of concrete channel lining to tie into the existing headwalls/wingwalls and hike & bike trail.  Project location is just east of Harris County Katy Park.
  • T101-00-00-X060 - consists of erosion repairs to include the installation of riprap, granular fill, well-graded mix, import fill and removal/replacement of backslope interceptors. 600 linear feet just east of Colonial Parkway.
  • T101-00-00-X061 consists of pipe removal and replacement. Location is about 350 linear feet downstream of Fry Road.
  • T101-03-00-X010 - consists of three (3) repair locations near Memorial Hermann Hospital in Katy, Texas.  One location is to fill an erosion with import fill, one location requires pipe removal and replacement and backslope interceptor and one location requires flowable fill to fill voids behind existing concrete channel lining.
  • T101-03-00-X011 - consists of erosion repairs to include bottom siltation removal, import fill and removal/replacement of backslope interceptors. Total length is about 5,400 linear feet beginning at Mason Road and continuing west upstream of Westside Parkway.
  • T101-07-00-X025 - consists of 2 erosion repair sites upstream of Mason Road. The first repair site includes removal/replacement of an outfall pipe, backslope interceptor over a manhole structure, sediment removal, import fill and riprap.  The second site includes pipe removal and replacement, sediment removal and side slope erosion repair with granular fill, import fill and riprap.
  • T101-08-00-X007 - consists of 2 erosion repair sites south of Morton Ranch Road.  The first site is the installation of a new outfall pipe, backslope interceptor and backslope swale regrade.  The second site is a side slope erosion repair with import fill, granular fill and riprap.
  • T101-09-00-X003 - consists of erosion repair site near the intersection of Franz Road and Grand Parkway and a removal/replacement of an outfall pipe and backslope interceptor near Kings Arms Way.
  • T101-10-00-X003 - consists of pipe removal and replacement and the installation of riprap near the intersection of Charlton House Lane and Shaw Perry Lane.
  • T103-00-00-X012 - consists of pipe removal and replacement to the existing manhole, import fill and riprap.  The location is at the dead end of Park Timbers Lane.
  • T103-01-00-X011 - consists of riprap installation at the outfall of two pipes near the intersection of Highland Knolls Drive and Cornerstone Place Drive.

Addicks Reservoir Watershed Repairs

  • U101-00-00-X023 - consists of erosion repairs to include the installation of riprap, granular fill, well-graded mix, import fill and removal/replacement of backslope interceptors. The existing hike & bike trail will need to be removed in some locations for the outfall pipe installations.  Total length of the project is about 4,700 linear feet from Morton Road to the confluence of U101-08-00.
  • U101-08-00-X008 - consists of 2 erosion repair locations. First location (about 170 linear feet upstream of Mason Road) is approximately 100 linear feet of side slope repair that will require riprap, granular fill, import fill and removal/replacement of backslope interceptors and related outfall pipes. The second location is downstream of Mason Road and will include concrete channel removal/replacement (existing locations), riprap, granular fill and import fill.
  • U102-00-00-X030 - consists of one repair locations just downstream of W. Little York Road at the detention basin. Repairs include granular fill and import fill to fill the erosion at the extreme event overflow location. Concrete slope paving will be installed at the extreme event overflow location.
  • U102-00-00-X031 - consists of erosion repairs to include the installation of riprap, granular fill, well-graded mix, import fill, sediment removal, removal/replacement of backslope interceptors and outfall pipes. Total length of 1,900 linear feet just upstream of Greenhouse Road.
  • U102-01-00-X017 consists of erosion repairs to include the installation of riprap, granular fill and import fill. Total length of 300 linear feet just downstream of Clay Road.
  • U102-18-00-X004 - consists of erosion repairs to include the installation of riprap, granular fill and import fill. Repair location is approximately 2,600 linear feet upstream of W. Little York Road.
  • U102-20-00-X006 - consists of erosion repairs to include the installation of riprap, granular fill and import fill. Total length of 60 linear feet just downstream of Clay Road.

The total cost for these channel repairs is expected to be approximately $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 Spring 2020 depending on weather.
