• Project: 2009 Storm Sewer Rehabilitation
Description: This project is for primarily trenchless, cured in place lining rehabilitation of approximately: 120 linear feet of 42" storm sewer pipe; 660 linear feet of 36" storm sewer pipe; 1,260 linear feet of 24" storm sewer pipe; and 120 linear feet of 24" storm sewer lead pipe. The work will be performed at various locations throughout the City, but primarily in Brittany Bay and Newport.
Purpose: The storm sewer pipe being rehabilitated is currently subject to infiltration due to soil movement causing pipe joints to separate and develop stress cracks. The infiltration carries surrounding soils with it, which leads to sink-holes adjacent to City street pavement and private structures. Making these repairs will reduce the City's risk for damages to its own street facilities and to private property.
Milestone: Under design

• Project: Clear Creek Heights Drainage
Description: The improvements are located all on the west side of IH 45, along the east side of Clear Creek Heights Subdivision, from its southeast corner to IH 45. Primarily, this is a slope paving project.
Purpose: To re-establish the flow lines, improve the efficiency of flow, and reduce maintenance of the drainage channel.
Milestone: Design is at 93% complete

• Project: Storm Water Improvement 2008
Description: The project consists of proposed slope paving (concrete lining) improvements to the following drainage rights-of-way throughout the City:
1. Interurban Ditch, north from FM 518, a project length of 900 feet; 2. Newport Ditch, north from FM 518, a project length of 900 feet ; 3. Bradshaw Road, southwest from SH 3 to the north line of CCISD's Elem. School # 25, a project length of 1,200 feet; 4. Nottingham Ditch from Calder Road to the Old Interurban Right-of-Way, a project length of 3,200 feet.
Purpose: To re-establish the flow lines, improve the efficiency of flow, and reduce maintenance of the drainage channels.

• Project: Robinson Bayou Bank Stabilization
Description: The project consists of stabilizing the banks of Robinson Bayou from Abilene Street to FM 270, a project length of approximately 2,300 linear feet, though the installation of concrete slope paving, gabions, and soil bioengineering methods.
Purpose: Portions of the existing banks are being lost due to the effects of scouring. A main concern is that root systems of adjacent trees could be undermined, causing a tree or trees to fall into the bayou, damming the bayou at the FM 518 or FM 270 bridges, with upstream flood damage.

• Project: Robinson Gully – Profile 6E
Description: This project will extend a drainage channel, approximately 1,500 feet in length, from the south side of SH 96, southerly to the intersection of Olive Street and Maryland Avenue in Shellside. Per the City's Master Drainage Plan, this channel should have a 100-foot right of way, and would be approximately 9 feet deep, with a 10-feet wide bottom. Right-of-way will have to be obtained across the Tuscan Development property and across a Centerpoint Energy electric transmission corridor. The channel would also cross an existing City park tract.
Purpose: The extension of this channel would provide an outfall to help provide drainage to the portion of Shellside that lies east of the Union Pacific Railroad, north of FM 646 and west of FM 270, which area regularly is subjected to street flooding during heavy rainfall events. The extreme rainfall event of April 18, 2009 further evidenced the need for drainage relief in this area.
