Stormwater Narrative
Existing Conditions:
The project site is located at 11 Zane Road in Midland, NC in Cabarrus County. The site is located on one of the lots
of the recently constructed Smith Industrial Subdivision. A web soil survey found soils on the to be made up of Tarrus
silt loam — Hydrologic Soil Group B, Herndon silt loam — Hydrologic Soil Group B, Kirksey silt loam — Hydrologic Soil
group C, and Chewacla sandy loam — Hydrologic Soil Group D. There is no existing on-site impervious area.
Proposed Improvements:
The proposed project consists of the construction of one building, a asphalt driveway and parking lot, and a gravel
lot. The lot will be curbed and will contain a batch plan and washout pit with a 39,770 sf warehouse. A sidewalk is
proposed along the asphalt driveway and the building will be served by a septic system and will be sprinkled.
Stormwater Treatment:
To provide treatment and attenuation for the site, a wet pond stormwater control measure (SCM) is proposed.
Stormwater will be collected by storm drainage systems that will drain into the wet pond to be treated.
The required treatment volume was calculated using the Simple Method for Runoff Volume.
