4f. List the total estimated acreage of all existing wetlands on the property:
0
4g. List the total estimated linear feet of all existing streams on the property:
285 feet
4h. Explain the purpose of the proposed project:*
The eAsting stormwater ditch will be transformed into a stormwater wetland. The project will be comprised of two wetland cells totaling about 1/4 of an acre. The wetland cells will be
planted with a variety of herbaceous wetland plants and include shallow and deep water areas for habitat and vegetative diversity. The wetland will treat runoff from 18 acre watershed
(7 acres of impervious surfaces (roads, building and parking lots)). The wetland is designed to capture and treat a 1" storm event and the outlet structure is sized to accommodate the
100-yr storm event.
41. Describe the overall project in detail, including indirect impacts and the type of equipment to be used:*
Using grant funding, Sound Rivers, Inc., NC Sea Grant and NCSU Dept. of Biological and Agricultural Engineering are developing demonstration projects for stormwater management at
schools throught the Neuse and Tar River Basins. The projects are intended to improve water quality by removing sediment, nutrients and other pollutants. Constructing a storm water
wetland in the area will increase water storage and improve water quality treatment and sediment capture compared to wasting conditions. The wetland will also provide educational
value as it will be used by science classes at the college. A track hoe and bobcat will be used to complete the excavation and earth moving. All cut material will be hauled away from the
site or stockpiled for use by the college in future projects.
4j. Please upload project drawings for the proposed project.

4h. Comments:
The existing ditch will be excavated and reshaped as part of the construction of the sormwater wetland. The excavation within the limits of the ditch will
consist of 106 CY of cut and 7.5 cy of fill.
E. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing the project:
This is a stormwater retrofit. An existing low quality ditch will be converted to a stromwater wetland that will provide treatment of runoff from a 18 acre
watershed.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Appropriate sized grading equipment is used in order to complete the project in a short time frame, thus minimizing disturbance through sediment and
erosion control. Measures will be taken to minimize any possible transport of sediment to downstream waters during construction.
2. Compensatory Mitigation for Impacts to Waters of the U.S. or Waters of the State
2a. Does the project require Compensatory Mitigation for impacts to Waters of the U.S. or Waters of the State?
r Yes r No
2b. If this project DOES NOT require Compensatory Mitigation, explain why:
This is a stormwater retrofit. No new development or impervious surfaces will be added to the site. The project is intended to enhance aquatic resources on the property and provide
ecosystem services of water quality improvement and habitat.
F. Stormwater Management and Diffuse Flow Plan (required by DWR) u
1. Diffuse Flow Plan
1a. Does the project include or is it adjacent to protected riparian buffers identified within one of the NC Riparian Buffer Protection Rules?
r Yes r No
If no, explain why:
Existing stormwater runoff is piped to the ditch. The existing stormwater drainage network will not be modified. The ditch will be improved by converting to a wetland.
2. Stormwater Management Plan
2a. Is this a NCDOT project subject to compliance with NCDOT's Individual NPDES permit NCS000250?*
r Yes r No
2b. Does this project meet the requirements for low density projects as defined in 15ANCAC 02H .1003(2)?
r Yes r No
2c. Does this project have a stormwater management plan (SMP) reviewed and approved under a state stormwater program or state -approved local government Stormwater
program?
r Yes
r N/A - project disturbs < 1 acre
3. Stormwater Requirements
r No
3a. Select whether a completed stormwater management plan (SMP) is included for review and approval or if calculations are provided to document the project will not cause
degradation of downstream surface waters.*
r Stormwater Management r Antidegradation

Enlargement of maps beyond the scale of mapping can cause

Coordinate System: Web Mercator (EPSG:3857)
Maps from the Web Soil Survey are based on the Web Mercator
projection, which preserves direction and shape but distorts
distance and area. A projection that preserves area, such as the
Albers equal-area conic projection, should be used if more
accurate calculations of distance or area are required.
This product is generated from the USDA-NRCS certified data as
of the version date(s) listed below.

NOTES:
1. WETLAND CELLS SHALL BE EXCAVATED 3-4" BELOW FINISHED GRADE AND 4" OF TOPSOIL ADDED AND INCORPORATED
INTO WETLAND SUBSTRATE.
2. AS GRADING OF SIDE SLOPES AND THE BERMS IS COMPLETED, SEED AND STRAW ALL EXPOSED AREAS AT THE END
OF WORK EACH DAY. A CONTRACTOR'S SEED MIX OR MIX OUTLINED ON THE PLANTING PLAN CAN BE USED TO THIS
END.
3. THE CONTRACTOR IS RESPONSIBLE FOR PLACING SEED AND STRAW ON ANY DISTURBED AREAS THAT WERE O
PREVIOUSLY COVERED WITH TURF GRASS.
