Re: Buffer Authorization for Pedestrian Bridge Replacements
Lake Daniel Park along North Buffalo Creek
Dear Sue:
This letter is submitted as certification of "No Practical Alternatives" in regard to impacts within the
stream buffer of North Buffalo Creek related to a proposed pedestrian bridge replacement along the
greenway through Lake Daniel Park in Greensboro. The bridge replacement plans were developed by
SKA Consulting Engineers. The measurements of existing impervious cover were done by City Parks
and Recreation Department staff.
Along the greenway trail in Lake Daniel Park is a very narrow bridge crossing over a tributary of North
Buffalo Creek. The greenway trail is heavily utilized by both cyclists and pedestrians, including some
walking dogs or pushing strollers. The bridge is barely wide enough to accommodate a cyclist, such that
it is dangerous for others to be on the bridge when they cross. Thus, the replacement of the bridge with a
wider crossing is a public safety issue. This bridge is noted as Bridge #2 is the SKA plans. Bridge #1
was replaced under an earlier contract. No buffer impacts were associated with that bridge replacement.
IMPACTS IN STREAM BUFFER AREAS
There are some minor buffer impacts associated with the bridge replacement. Existing impervious cover
within the stream buffer is comprised of the concrete greenway trail, concrete bridge abutments, and some
areas where concrete has been placed to stabilize slopes that were prone to erosion. Proposed impervious
cover within the buffer is for new bridge abutments, footings for protective safety railings, and concrete
sidewalks approaches to the wider bridge. The City has measured the existing concrete vs. the proposed
concrete in the areas at the ends of the bridge.
The proposed concrete for the bridge is 84 sq. ft. on each end of the bridge, due to a slightly wider bridge
and abutments. Total impervious cover is 168 sq. ft. City staff measured the total existing impervious
cover within the same area as 146 sq. ft.
Greenway/hiking trail impacts are listed in the Jordan Buffer Rules as "Allowable with Restrictions".
The grading and vegetative stabilization for the disturbed areas at the ends of the bridges will be done
according to best practices for preventing erosion and providing filtration of flows from the impervious
areas to the extent practicable.
FACTORS PREVENTING IMPLEMENTATION OF PRACTICAL ALTERNATIVES
The following factors prevent implementation of practical alternatives to the proposed buffer impacts
associated with the proposed pedestrian bridge replacement:

• Public safety dictates a need for a wider bridge crossing and the associated wider abutments and
greenway approaches.
• The safety rail extensions at either end of the bridge are intended to protect trail users from
veering off of the sidewalk and into the stream as they approach the bridge. There are existing
safety rails, but they are not sufficiently protective. The new safety rail extensions will have
smaller openings consistent with the railings for the bridge to meet safety standards. These
extensions need to be supported by the concrete foundation system.
EFFORTS TO MITIGATE BUFFER IMPACTS
The existing concrete previously added for erosion protection within the bridge construction areas will be
removed and appropriate vegetation will be established, with erosion control matting added if and where
needed.
Thank you for your assistance authorizing buffer impacts associated with the pedestrian bridge impacts.
Let us know if you require any additional information for authorization of the above -listed activities
impacting the stream buffers on North Buffalo Creek in Lake Daniel Park. A GIS figure of the area, the
proposed construction plans, and the City staff s impervious cover measurements are attached for your
reference.
