NC Stormwater Statute Amended
In 2007 the Legislature passed an amendment to the North Carolina Stormwater
General Statute that was approved as a line item in the North Carolina State Budget.
The amendment limits the impervious portion of parking lots to 80% of the built-upon area.
LIMIT IMPERVIOUS SURFACES FOR VEHICLE PARKING
SECTION 6.22.(a) G.S. 143-214.7 is amended by adding a new subsection to read:
(d2) Any area designed for use as a vehicle parking area, except for covered
vehicle parking areas or multilevel vehicle parking areas, shall not exceed eighty
percent (80%) built-upon area, as defined in S.L. 2006-246. The remaining area
designed for use as a vehicle parking area shall meet:
(1) The design requirements for a permeable pavement system, as
determined in guidance documents prepared by the Department or
(2) Other design requirements for stormwater management approved by
the Department, including, but not limited to, the use of
(i) grass and other pervious surfaces and
(ii) bioretention ponds, cisterns, and other water retention devices.
SECTION 6.22.(b) The Environmental Review Commission may study
issues related to the use of pervious surfaces for vehicle parking areas,
including the costs associated with the use of pervious surfaces,
the impact to the environment of stormwater runoff, and
the practices of other states with regard to stormwater best management practices.
The Commission may report its findings and recommendations, including any legislative proposals,
to the 2007 Regular Session of the General Assembly when it reconvenes in 2008.
Of the funds appropriated to the General Assembly, the Legislative Services
Commission shall allocate twenty-five thousand dollars ($25,000) to conduct this study.
SECTION 6.22.(c) Subsection (a) of this section becomes effective October 1, 2008,
and applies to any area designed to be used for vehicular parking for which an application
for a building permit, a request for a zoning reclassification, or a subdivision plat is
filed in the county or city in which the area is located on or after that date.
The remainder of this section is effective when this act becomes law.

EDI Seminar Notes
Pervious Concrete Seminar:
Bruce Ferguson made a presentation on Pervious Concrete Pavement
at a seminar arranged by Estes Design on July 20, 2007 in Charlotte.
Notes from the seminar are available on our Presentations page.
Bruce Ferguson has nationally-renowned knowledge and experience in storm water infiltration.
He is Professor of Landscape Architecture and Director of the School of Environmental Design
at the University of Georgia. He is a landscape architect who has specialized in environmental
management of urban watersheds.
Ferguson recently completed the first comprehensive guide to porous pavements; a new
technology, which he says, is “potentially the biggest development in urban watersheds
since the invention of the automobile.” Porous Pavements was released
by CRC Press in early 2005. For his research, Ferguson surveyed 280 installations of all kinds
of porous pavements, in all parts of North America.
