Staff has reviewed your initial submittal for fill in the floodplain and a bridge expansion at 5th
Street Station. We have a few comments which are listed below:
Engineerinje and Water Resources
1. The fill in the floodplain should be minimized if at all possible. The grading and sections
provided so far seem to fill in most of the floodplain areas, confining the channel to a smaller,
faster section, with no storage in the fringe on the site, and greater possibility for channel
erosion, or flooding on the opposite bank. Rather than a maximum possible scenario, the
actual grading necessary for the site and road should be used.
2. The proposed floodplain on the opposite side of the creek should also be shown. It is currently
flooding much of the road and development on the opposite side at 5th Street, and filling in the
site would appear to make this worse, or at least more frequent, from a common -sense
perspective.
3. Please provide the LOMR referenced for the flow value used. It is not clear where this comes
from, or how it correlated to the current FIRM.
4. It is difficult to correlate the old HEC -2 models for the existing FIRM elevations to the new HEC -
RAS models, but it appears the new models are using much increased coefficients on the
overbanks, and decreased coefficients in the channel. (HEC2, 0.07, 0.045; HEC -RAS, 0.12, 0.03)
The result, of course, appears to confine more of the modeled flow to the channel, improving
floodplain results unrealistically. A valid model to model, and floodplain to floodplain,
comparison should use the same parameters.
Planning
The following comments related to the proffers are provided by Claudette Grant:
1. Most of the proffers do not relate to flood plain issues; however, Proffer 7: Moore's Creek
Erosion and Buffer Projects does speak to stream bank restoration and stream channel
stabilization. Make sure the proposed disturbance along Moores Creek will not be an issue for
proffer 7.
