Partner with Charlotte on Stormwater Management Projects

The Gleneagles Project is primarily focused on replacing an existing CMP culvert near 3810 Gleneagles Road.  The existing culvert is 8.7’ high by 7.8’ wide and is being replaced with a 10’ wide and 7’ tall RCBC.  The culvert replacement is occurring to address aging infrastructure and to improve the reliability of infrastructure for the traveling public.  In support of this culvert replacement, we are dredging the downstream pond which is located on the Quail Hollow Country Club near the 15^th hole.  The dredging will remove sediment that has built up near the downstream end of the existing culvert and prevent sediment transport downstream which would negatively impact existing ponds and habitats.  In addition, we will be adding inlets and upgrading roadside drainage on Out-Of-Bounds Drive which has significant spread in larger storm events from road drainage.  The work on Out-Of-Bounds Drive will increase the safety of the traveling public using that roadway during rain events.

The Brooklain-Coulwood Storm Drainage Improvement Project is bordered by Cathey Road to the east, Brooklain Drive to the south, Waycross Drive to the west, and Coulwood Drive to the north.  This construction project involves addressing flooding concerns and structurally deficient City pipe system at a total of 4 culverts.  An analysis of existing conditions was performed to determine portions of the storm drainage system needing improvement as well as planning analysis of improvement alternatives.  Design phase efforts will be performed as well as construction of needed improvements.

Asset Management performed an inspection of the dual 60-inch CMP culverts with paved inverts beneath Arbor Glen Ln in June 2023. Proposing CIPP lining on the dual 60″ CMP culverts. Replacing the two headwalls. There are improvements on the side system of the culverts. Remove and replace a catch basin along with 15″ RCP. Remove and replace a single catch basin with a double catch basin. Remove and replace a section of 24″ RCP.

Collective Storm Drainage Improvement Projects Series AJ will involve 6 projects throughout the City of Charlotte, 1614 Lombardy Circle, 2033 Teddington Drive, 2316 Kilborne Drive, 10513 Moss Mill Lane, 435 Norwood Drive, and 5447 Kerry Glen Lane. These projects will consist of reinforced concrete pipe replacement and realignment. The project pipe will consist of a range of different sizes from 15 inch to 36 inch as well as some elliptical pipe.  These projects will also consist of CIPP liner, storm drainage structure replacement, non-standard endwalls, full depth asphalt, curb and gutter, concrete driveway, foundation assessment, foundation protection, boulder toe, soil lifts, and watermain replacement.

The Collective Culvert SDIP 1 consists of five separate drainage culverts at the following locations: N Kings Drive (between Elizateth Ave & Armory Dr), Harris

Houston Road (between Astoria Dr & Bridgehampton Dr), Allister Drive (between Elwood Dr & Walnut Wood Dr), Parview Drive (near 4701 Parview Dr N), and Pence Road (between Bandy Dr & Pence Pond Ln).  The improvements will include lining or rehabilitating existing culverts and/or replacing existing culverts.

The need for this construction project is to improve the storm drainage infrastructure (i.e. pipe systems and culverts) to reduce flooding and to enhance degraded stream reaches to reduce erosion and improve water quality.  This project is under review.  Location and project details will be provided after the review is complete.

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.

Project consists of lining 556 LF of 42 inch CMP and 131 LF of 15 inch RCP with CIPP.  Eight existing drainage structures will be removed and replaced and two additional structures will be added. 221 LF of 15″ RCP will be removed and replaced. Chemical grouting joint repair will also be installed at approx. 15 locations throughout the 42″ CMP.

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.

The storm drainage improvement project is for the area in and around Hill Street.  The construction project boundaries are Tryon Street to the southeast, Trade Street to the northeast, South Cedar Street and West 1st Street to the north, and Palmer Street to the southwest. The project includes storm drainage improvements that reduce house and street flooding or will repair failing infrastructure.

The Shade Valley Pond Repairs project was initiated in order to relieve the City of significant efforts and costs of ongoing pond maintenance.  Proposed improvements to the pond are intended to address nuisance vegetation, increase storage capacity, address geese issues, and enhance the overall aesthetics of the pond.  Goals are to restore pond to “below normal pool” volumes via dredging of forebay and main pool to increase water quality function and remove available nutrients contributing to duckweed and algal blooms.  The entirety of the pond and littoral shelf will be replanted with wetland plantings and trees to enhance aesthetics and decrease attractiveness of pond to geese. Geese preventative measures are proposed to establish plantings.
