Broadpointe Industrial Facility
Stormwater Management
The Broad pointe Industrial Facility site is a parcel that previously had been built up with fill from a
neighboring site and had been graded to a level grade. A substantialstockpile of dirt had been added on
top of this graded site, and there were existing stormwater managementsystems in place. Duke Energy,
who had been the previous owner of this parcel, designed and constructed a project on a portion of this
site. They updated the skimmer basins on the NW and N E corners of the lot that was to be sold to
Min kles Broad pointe II LLC., as well as installed silt fence, temporary diversion ditches, pipes lope drains,
and outlet protection. Duke Energy had conducted some land disturbing activities on the portion of the
site that was to be sold; they removed most of the soil stockpile. This was the condition of the site when
it was sold to Min kles Broad pointe II LLC.
The portion of the parcel that Min kles Broad pointe purchased constituted of 25.07 Acres of land. The
proposed project is to construct an 119600 SF industrial facility, with a truck court in the back and
parking along the front, with 68 parking spots. The total built upon area of this project is 5.24 Acres, only
20.9% of the site, thusthis project is considered a low -density project.
During construction the two skimmer basins that are currently on site will be modified to manage the
proposed facility and all on -site and off -site stormwater run-off. These will remain until the final
stormwater network has been set in place and stabilized. Ditches will convey water around thee dge of
the facility to a ditch that then feeds into the French Broad River, and to a floodway. Storm structures
and pipes have been added at the back of the project site so convey water from the truck court to the
bottom of the slope. All outlets will have proper dispersion and dissipation measures
