Summary of Citizen Involvement
- Questionnaires were sent out to get public feedback regarding storm water related issues in the
neighborhood.
- The purpose of the first public meeting, held September 14, 2006, was to present the results of the
existing conditions analysis and to obtain feedback from residents, so the existing conditions models
could be adjusted to better match actual field conditions.
- The purpose of the second public meeting, held December 21, 2007, was to present results of the
public input from the first public meeting, and to present results of the alternative analysis.
-
The purpose of tonight’s public meeting (meeting #3) is to kickoff the real estate phase and to present
the preliminary construction drawings.
The Easement Acquisition phase has started and Julie Millea will meet with the individual
homeowners to discuss the acquisition process and to go over the easement exhibits.
Presentation by Josh Letourneau, Consultant:
Brief Summary of the Project Background/History
- Existing Conditions: The results from the existing conditions analysis were presented. A few
problem areas of interest were the existing Kenlough culvert and the existing pipe system adjacent to
Briabend Drive (beneath the storage facility units).
- Revisions Based on Citizen Feedback: During the 1st public meeting, homeowners provided feedback
after reviewing the results of the existing conditions analysis. Armstrong Glen used this feedback and
revised the existing conditions model to better capture the actual magnitude of flooding witnessed in
the neighborhood.
- Developing Alternatives: Based on the results of the existing conditions analysis, Armstrong Glen
and the City of Charlotte developed numerous proposed alternates that provided varying levels of
flood protection throughout the neighborhood. A single alternate was chosen based on many factors
including level of flood protection, construction costs, impacts from construction, etc. This chosen
alternate has become the design for this project.
- Jennifer Barker summarized the demolition of the steam-side Firwood Lane homes. Six of the seven
total homes have been destroyed. The demo of the seventh house is currently out to bid.
Brief Summary of the Project Design
- Josh Letourneau presented the preliminary design including locations and sizes of new storm drain
throughout the neighborhood.
Questions / Comments
Citizen at 501 Kenlough Drive –
What does RCP mean?
Josh Letourneau Reinforced Concrete Pipe.
Citizen at 517 Kenlough Drive –
What improvements will we see as a result of this project?
Jennifer Barker No work is proposed downstream of the Firwood Lane/Kenlough Drive intersection. However, the
exiting Kenlough culvert will experience a significant reduction in flow once the proposed detention
facilities are constructed upstream.
Citizen at 501 Kenlough Drive –
What slope will the detention facility have?
Josh Letourneau The detention facility will have mostly 2:1 side slopes. The steep slopes, along with dense vegetation,
will provide a natural deterrent from unwanted pedestrian access.
Jennifer Barker –
Mecklenburg County will require a meandering slope of 3:1 (on the park side) to provide a more “park
like” environment and to accommodate a trail in the future.
Citizen at 501 Kenlough Drive –
Will there be grading in my yard?
Josh Letourneau Yes. Due to the extent of the required detention, your yard will be impacted by tie-in grading. The
grading design is not final so there will be opportunity to provide feedback regarding work on your
property.
Jennifer Barker –
We might design a retaining wall around your property to quickly tie in the grading, whereby resulting
in a more level yard.
Private Meeting with Homeowner at 501 Kenlough Drive
-
-
Homeowner likes the idea of having a retaining wall installed so his yard can be more “usable”.
The City promises not to disturb the existing concrete patio.
Homeowner requests his fence to be relocated along the wall.
Homeowner wanted to know how his yard will drain behind the proposed retaining wall/berm. The
Consultant mentioned that the yard runoff would be directed to an existing drop inlet currently
connected to the existing 5’x8’ box culvert adjacent to his house.
Homeowner wanted to know how the proposed sidewalk will impact his yard. The City summarized
the two types of easements required for the proposed sidewalk. There will be an 8 foot planting strip,
6 foot sidewalk, permanent sidewalk easement 2 feet off edge of sidewalk, and a temporary
construction easement 5 feet from the permanent sidewalk easement.
Public meeting adjourned @ 8:15 p.m.
