General construction sequence
Carmel Stormwater Pollution Prevention Plan Review
14 Digit Watershed Hydrologic Unit Code
Name of All Receiving Waters
If the discharge is to a municipal separate storm sewer, identify the ultimate receiving water
Project Name:Ed Martin Buick GMC Parking Lot Expansion
Estimate of peak discharge for post construction conditions (10-
year)
Soils map of the predominant soil types including:
Locations of specific points where stormwater discharge will
leave the site.
Description of potential pollutant sources associated with the
construction activities
Locations where stormwater may be directly discharged into
groundwater, such as abandoned wells or sinkholes
Location of proposed soil stockpiles, borrow, and/or disposal
areas
These areas shall be included as part of the plans whether they occur on or off site.
Brief description of how the site has accommodated the existing soil
limitations
Temporary and permanent stormwater quality measures:
Temporary and Permanent surface stabilization methods
appropriate for each season
Each plan should contain multiple stormwater pollution prevention measures. All measures will not be installed at
the same time. Various measures will be installed at different times throughout the construction process. Some
will be installed prior to land disturbance, and others may not be installed until work at the site progresses to an
area where they are necessary. Each proposed measure should be identified in the sequence as to when it is to be
installed in relation to the land disturbing activities.

Comments
1)Construction limits should be expanded to include all disturbance, including the installation of
temporary storm water controls. Due to the pond expansion, it may be beneficial to provide a
initial storm water plan showing existing conditions and initial storm water controls.
8)
a.Please show location of temporary construction entrance. Perimeter protection should extend
along the proposed edge of curb in the southern portion of the site that borders the existing pond
and proposed pond expansion. A protection should be shown protecting the existing outlet of the
pond. Please provide controls needed to expand the existing pond. A dewatering control is
needed to draw down the existing pond prior to grading. A raised or floating intake should be
utilized and then a protected sump should be used to keep the levels down during grading. Clean
water can be pumped directly to the outlet.
d.Provide a detail for the dewatering controls (draw down intake, sump intake during grading).
Provide a detail for the existing outlet protection. This does not need to be as invasive as a rock
check dam. It could be a check dam made of filter tubes.
9)
11)Please provide a planting species lists for the native wetland shelf/pond banks and indicate the
parameters of the plantings on the SWPPP.
The method of expanding the proposed pond should be detailed in the construction sequence.
