Sherman's Hollow at Lake James (Lake James Development) Stormwater Management
Plan Modification
Dear Mr. Deal:
On August 22, 2017, the Division of Water Resources — Water Quality Programs (Division) received a
request for a modification to the approved stormwater management plan for the Sherman's Hollow at Lake
James Subdivision. The Division has determined that your application is incomplete and cannot be
processed. The application is on -hold until all of the following information is received:
On November 16, 2016 the Division issued a 401 Water Quality Certification written authorization
for the Lake James Development for coverage under Water Quality General Certification Number
3890. Condition #3 of the authorization states that the Division approved the associated
stormwater management plan (SMP) ... which specify a stormwater drainage system that consists
primarily of vegetated swale conveyances. The modified stormwater management plan which is
based on existing/as-built conditions of the site indicates a significant percentage of riprap lined
swales. The Division does not consider riprap lined channels to meet the intent of the stormwater
requirement of vegetated swales, regardless of whether some vegetation is present within the
channel. The proposed SMP does not provide adequate calculations orjustification for the
proposed riprap lined channels in lieu of vegetated swales/conveyances. While the Division
recognizes that riprap is often necessary and appropriate for adequate erosion control during
construction activities, upon project completion the channels must be restored to vegetative
swales as approved. For significantly steep areas, riprap check dams may be used to slow the water
in the channel, or the Division recommends that you consider reinforced turf or other supportive
vegetative method of conveyance. The Division may approve alternative designs, such as minor
areas of non -vegetated conveyances, when technical justification is provided and the alternative
design does not compromise water quality protection. Please provide a stormwater management
plan that includes proposed restoration of existing riprap lined stormwater conveyances to
vegetated swales where calculations indicate that vegetated swales will be stable and provides
additional justification for any existing swales that are proposed to remain lined with riprap.
