CONDITIONS:
SHORT TERM:
Copy of stormwater submittal to DWQ for Phase II post constructions.
A stormwater statement shall
be provided. We are particularly concerned about the wetland channels throughout the development. We would like to see an analysis that addresses whether or not there will be any adverse
impacts to adjacent properties for the 100 year event. This should include a channel analysis that identifies the change in normal depth.
The analysis needs to include the following:
Provide pre vs post runoff for the 10-year, 25-year and 100-year storm. Include maps to show the drainage basin areas.
The time of concentration
for the pre vs. post condition. The time of concentration should decrease with piped flow versus the original overland flow.
The channel analysis should be performed at a point in the
lower quarter of the drainage channel where flow is constrained because of a flat and narrow section.
LONG RANGE:
A copy of the erosion control plan submitted to the appropriate authority,
if such a plan is required.
Erosion Control Measures and Details
Detailed topographic information. A minimum 2 foot contours is required. Vertical datum provided.
