Re: UT to Falls Lake Buffer Mitigation Site
DMS ID #95389 —CLOSEOUT ACCEPTANCE LETTER
Dear Ms. Allen,
On July 31, 2023, the Division of Water Resources (DWR) received a formal close-out packet from
you on behalf of the Division of Mitigation Services (DMS) requesting approval to close-out the
subject site for monitoring and maintenance of the riparian areas where riparian buffer credit and
nutrient offset credit is generated. On July 18, 2023, Katie Merritt with DWR visited the subject site
with staff from DMS (Jeremiah Dow, Emily Dunnigan) and to assess the vegetation and overall site
conditions. The asset map and asset table, both initialed by Ms. Merritt on October 23, 2023, are
attached. Due to the location of this mitigation site, Nutrient Offset credits can only be provided in
the Falls Lake Watershed.
This mitigation site is located in the Upper Falls Watershed of the Neuse River Basin and within the
8-digit HUC 03020201. Due to the location of this mitigation site, Riparian Buffer Credits can be
provided for permitted impacts anywhere within the Neuse River Basin 8-digit HUC 03020201.
However, Nutrient Offset Credits can only be provided for permitted impacts within the Falls Lake
Watershed.
DWR has reviewed the revised close-out request and the following is approved:
