Subject: Comments on Gateway DWR # 20151031 V2
Brad,
The DWR has the following comments on the project application:
1. Detail drawings are needed for the wetland impacts and they should also include cross sections where applicable
(generalized cross sections are acceptable where there is similarity)
2. For the wetland impacts for the road crossings and parking areas, what methods of avoidance and minimization
were used? Is the fill sloped (3:1) or are retaining walls being used?
3. Please indicate on the plans, where they are planning to use pervious pavement.
4. It is mentioned that the stormwater feature for the site will be constructed as a rain garden. It is also mentioned
that the stormwater feature will be used for additional future development. Why construct a rain garden only to
dig it out in the near future?
5. For mitigation purposes, the State requires a minimum ratio of 1:1.
6. No access road is shown on the plan to access the stormwater pond for the required maintenance. Please show
this on the plans and if additional wetland impacts are required.
7. The major road into the development is shown to have a median. If the road width were reduced (by not having
a median) could any reductions in wetland impacts be possible? (i.e. #4 or reduce #1)?
8. The major road into the development into the project is shown as a dead end. This indicates a potential of future
wetland impacts, which then questions the single and complete development this project is being reviewed
under. You may want to consider a T or cul de sac as an option.
