The Valleybrook SDIP includes the design and construction of needed improvements in the Valleybrook Storm Drainage Improvement Project (SDIP) area.  The improvements include CMP culvert replacements and associated channel improvements.  The Valleybrook SDIP is bordered by Folger Drive to the north, Sardis Lane to the south, Ramsgate Road to the west and Carosan Lane to the east.  This project area is within a drainage area of approximately 450 acres.

Asset Management performed an inspection of the dual 72-inch CMP beneath N Hoskins Road in May 2024. Several holes with visible soil were observed during the inspection. Severe road settlement was also noted above the culvert. The City intends to replace 105LF of duel 72” CMP with 105LF of 11’x8” RCBC; add (2) Non-standard headwalls; add 120 LF of 54” RCP; remove 21LF 36” RCP; add (2) DCBs; Add (1) CB; replace approx. 253LF of 12” sewer; replace approx. 120LF 8” Sewer;  replace (4) sewer manholes; Add/replace approx. 382LF 2’6” C&G; asphalt replacement

Project initiated due to several holes and corrosion in the existing 16.25’x9.5’ elliptical pipe. Cracks in the headwalls were also observed. The City intends to replace 81LF 16.25’x9.5’ elliptical pipe with 81LF of 14’x9’ RCBC; add (2) Non-standard headwalls; add 213 LF of 24” RCP; replace 56LF of 15” RCP; add (3) CBs; Add (2) JBs; plug and fill approx. 220LF of 18” RCP; Add/replace approx. 600LF 2’6” C&G; channel grading; asphalt replacement.

Proposed installation of residential access bridge, stream improvements, and storm drainage infrastructure in Perth Court area.

The project involves analysis of existing conditions to determine portions of the storm drainage system needing improvement, and design and construction of needed improvements. The existing storm system experienced a pipe collapse due to poor condition of the pipe. To address the request and meet level of service design standards the project will remove and replace the existing Storm Drainage Infrastructure within the project scope.
Proposed improvements include removing approximately 343 LF of 18″ storm water pipe and replace with approximately 410 LF of 24″ storm water pipe, add 2 double catch basins and associated items, and remove and replace approximately 357 LF of 8″ sewer pipe, and 3 sewer manholes.
