3. Project Description
3a. Describe the existing conditions on the site and the general land use in the vicinity of the project at the time of this
application:
Undeveloped land. The surrounding parcels are business park commercial.
3b. List the total estimated acreage of all existing wetlands on the property:
0.714
3c. List the total estimated linear feet of all existing streams (intermittent and perennial) on the property:
6033 LF. Intermittent +perennial +jurisdictional)
3d. Explain the purpose of the proposed project:
Proposed college campus including buildings, parking, and roadway improvements
3e. Describe the overall project in detail, including the type of equipment to be used:
There are 4 areas of buffer impact within the scope of the proposed project:
(1) Impact to buffer within the property from sidewalk construction and culvert extension. The majority of this impact is within
the ROW and only 15.5 sf within the property.
(2) Roadway stream crossing within existing access easement to allow for circulation from northwest adjacent property. A
stream spanning option was not viable due to the low road clearance. A 6’ x 6’ culvert is proposed to carry the existing stream
flow. The outflow from the western pond’s primary spillway is also proposed to be conveyed via this 6’x 6’ culvert to minimize
areas of buffer and stream impact. [This impact includes area on- and off-site]
(3) Installation of RCP storm drainage pipe from proposed east wet detention pond to existing natural draw within buffer. The
outfall is being conveyed to the existing draw that coincides with the top of bank, because the available area outside of the
buffer precludes the use of a level spreader.
(4) Installation of DIP sewer pipe. There is sufficient clearance below the stream to have the sewer pipe installed without
impact to the stream channel. The buffer impact shown in zones 1 and 2 are due to clearing of trees within the buffer as
required for the utility easement. [This impact includes area on- and off-site]
Equipment used to install the stormwater and sewer pipes will be an excavator and bore and jack, respectively.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
An open-bottom stream crossing was preferred within the existing access easement; however, due to the low elevation of
the existing drive there is not sufficient clearance between the stream bed elevation and the proposed road elevation to
contain both the expected stream flows and roadway profile. Designers explored possible solutions with recently-released
open-bottom stream crossing proprietary products that utilize low profile materials. Site constraints did not allow this
option. Therefore, a buried culvert is proposed to mimic a natural stream channel and minimize impacts from the road
stream crossing construction. There will be no backwater impacts on upstream parcels, because the entire reach of the
stream headwaters is contained within the site.
The design of the rip rap dissipation pads at the end of each culvert has been modified to reduce impacts on the stream.
Specifically, where possible (all impacts except the road crossing over Stream A where bedrock is present) the existing
elevation of the stream bottom will be maintained by burying the required rip rap. This will allow for a permanent stream
impact without a permanent loss of water. Therefore mitigation is not required for the specifically designed rip rap areas.
See section 3e for additional supporting information
b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The roadway construction will be done with hand labor and small supporting equipment. Retaining walls are proposed to
reduce the buffer impact as compared to an earthen embankment. All rip rap dissipaters will be installed with manual
labor. Buried storm pipe will be installed with the smallest bucket that will support the proposed pipe diameter. The sewer
line will be installed with the jack-and-bore method to reduce surface erosion from digging and avoid stream impacts.
Selective tree clearing will be completed with manual labor to provide clear sanitary sewer easement.
See section 3e for additional supporting information
