this application:
Roadway typical cross sections consists of curb and gutter with an existing, maintained herbaceous
shoulder, rough graded for future trail installation. The surrounding area consists mostly of
developed, commercial sites.

footprint. Standard Concrete mixer trucks will be used to provide concrete. No unique methods of
construction or equipment is anticipated.

D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Sidewalk to be installed within existing public right of way. Erosion control measures will be installed
prior to land disturbing activity and will be maintained until final vegetative cover is established.
Standard walking trail/sidewalk detail specifies a 5 foot utility strip adjacent to the back of curb, with a
5 foot wide sidewalk/walking trail. This trail is designed to be 6 feet wide and installed directly behind
the back of curb to reduce encroachment into the buffer zones and to keep it within the existing right of
way.
One of the main goals of the proposed trail is to expand the pedestrian network to connect the
MacGregor Office Park to the MacGregor Village Shopping Center. Both of these sites are located on
the south side of Edinburgh South Drive. The trail is to be installed on the south side of the road as
well in order to provide a safe route for pedestrians, with the no road or mid-block crossing across
Edinburgh South Drive.
1 b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction
techniques.
Erosion control measures will be installed prior to land disturbing activity and will be maintained until final
vegetative cover is established. Site access is anticipated to occur from the existing roadway facilities.
Roadway will be kept clean during all construction phases. ,
