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:
Site was configured to perpendicularly cross wetland and buffer zones at one location to access the site. The City requested a second temporary
emergency access.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques:
Limits of disturbance will clearly be marked and silt fence used along wetlands and buffer zones downslopes of any disturbance along with temporary
diversions and sediment traps upslope of wetland/buffer areas.
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?
f Yes r No
2b. If this project DOES NOT require Compensatory Mitigation, explain why:
Not required due to the type of buffer and limited disturbance.
F. Stormwater Management and Diffuse Flow Plan (required by DWR)
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?

Directions (same for pre -development and post -development tables):
> Enter the acres of each type of land cover in the green boxes. The spreadsheet will calculate all of the values in light blue.
> Compare total areas of development in pre- and post- tables for consistency (bottom of column (2)), and also for consistency with
the site plans. If all of these values are not the same, there is an error that must be corrected.
> Unless drainage onto the development from offsite is diverted around or through the site, offsite catchment area draining in must
be included in the acreage values and treated.

Drainage Area Number:
Stormwater Wetland Operation and Maintenance Agreement
I will keep a maintenance record on this BMP. This maintenance record will be kept in a log in a
known set location. Any deficient BMP elements noted in the inspection will be corrected, repaired or
replaced immediately. These deficiencies can affect the integrity of structures, safety of the public, and
the removal efficiency of the BMP.
Important maintenance procedures:
— Immediately following construction of the stormwater wetland, bi-weekly inspections will be
conducted and wetland plants will be watered bi-weekly until vegetation becomes established
(commonly six weeks).
— No portion of the stormwater wetland will be fertilized after the first initial fertilization that is
required to establish the wetland plants.
— Stable groundcover will be maintained in the drainage area to reduce the sediment load to the
wetland.
— Once a year, a dam safety expert should inspect the embankment.
After the stormwater wetland is established, I will inspect it monthly and within 24 hours after every
storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County). Records of operation and
maintenance will be kept in a known set location and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall be repaired
immediately.
