DWQ #12 0095
Dear Ms Homewood
In response to your letter dated February 27 2012 we offer the following comments and additional information
The USACE concurred with the earlier mapping conducted by ECS (and submitted with the initial PCN
Application package) and has determined that the area in question is not a wetland The following email was
received from Michael Brame at ECS on February 28 2012
1 spoke with Mr Craig Brown with the U S Army Corps of Engineers (USACE) on Thursday moming [2123112]
He is one of two replacements for Mr Andy Williams with the U S Army Corps of Engineers (ong►nally venfied
the site) while Mr Williams is working out of the USACE corporate office in Virginia Dunng a phone
conversation Mr Brown indicated that he was going to be in the vicinity of the site and planned to revisit the site
on Thursday February 23 1 spoke with Mr Williams on Fnday February 24 and he confirmed that Mr Brown
had in revisited the site Mr Williams informed me that Mr Brown concurred with the previous delineation
conducted in August 2011 by ECS and venfied by Mr Williams with the USACE in September 2011 Mr Brown
did not identify wetland areas that were left unflagged on the site
2 Students attending this new classroom budding are the most severely impacted students with regard to
developmental delays and Autism therefore the children attending the school have unique needs that impact the
site design The pickup and drop off locations from the busses serving the Autism students must be separated
from the traditional budding busses so the needs of these students can be more appropriately addressed The
school administration and staff required that a separate drop -off location be developed to provide increased safety
and containment for this student population They typically have moderate to severe sensory issues and are
easily distracted Simplifying the process and limiting the number of students in one area reduces the likelihood
for students to flee during the unloading process
To ensure student safety most schools designed today and all schools with Guilford County Schools jurisdiction
utilize separate bus and car access areas Allowing cars into the bus areas makes it too easy for a student to be
hit by a vehicle Therefore passenger car access through the existing bus area which serves existing
elementary and middle schools is contradictory to distnct policy for student safety Not only would there be
student and vehicular conflict during the three schools arrival and dismissal times but the additional vehicular
traffic serving the new school would negatively impact student safety at existing outdoor play sports and learning
areas throughout the day The potential impacts to student safety do not allow for access to the new school from
the existing bus loop

We reviewed possible access to the new budding site at a location further downstream crossing the stream in
only one location However due to the location of the existing elementary school and the associated fill slope and
the turning radius associated with the school busses and emergency vehicles it is not feasible to cross further
downstream Although the actual footage of piped stream may be reduced through a downstream option the
access road would parallel the stream after the crossing impacting a substantially higher amount of stream buffer
and therefore degrading an increased amount of stream channel After careful consideration the current
configuration most closely met the programmatic needs for the facility and provided the most secure
environment for the students while avoiding environmental impacts to the maximum extent practical
3 Please see the enclosed Overall Watershed Plan Sheet (C 5 0) for the location of the proposed bioretention cells
that are being reviewed by the City of Greensboro Technical Review Committee as part of the site plan review
process
4 The City of Greensboro Stormwater Management Division is reviewing the plans to ensure the Jordan Lake
Riparian Buffer Rules are met The plan is currently in review
5 Please see the enclosed impact maps for additional information on the nature of the proposed temporary and
permanent impacts and restoration requirements after removal of the temporary impacts
6 Please see the enclosed Access Road Plan /Profile Sheet (C 6 0) for the proposed roadway profile and
associated nprap pad outlet protection detail
Should you have questions or need additional information please contact me at 336 3101481 or via email at
