1
Clearing Limits
Before beginning land disturbing activities are all clearing limits, natural resource areas (streams, wetlands, buffers, trees) protected with barriers or similar BMPs? (high visibility
recommended)
X
2
Construction Access
Construction access is stabilized with quarry spalls or equivalent BMP to prevent sediment from being tracked onto roads?
X
Sediment tracked onto the road way was cleaned thoroughly at the end of the day or more frequent as necessary.
X
3
Control Flow Rates
Are flow control measures installed to control stormwater volumes and velocity during construction and do they protect downstream properties and waterways from erosion?
X
If permanent infiltration ponds are used for flow control during construction, are they protected from siltation?
X
4
Sediment Controls
All perimeter sediment controls (e.g. silt fence, wattles, compost socks, berms, etc.) installed, and maintained in accordance with the Stormwater Pollution Prevention Plan (SWPPP).
X
Sediment control BMPs (sediment ponds, traps, filters etc.) have been constructed and functional as the first step of grading.
X
Stormwater runoff from disturbed areas is directed to sediment removal BMP.
X
5
Stabilize Soils
Have exposed un-worked soils been stabilized with effective BMP to prevent erosion and sediment deposition?

Stabilize Soils
Cont.
Are stockpiles stabilized from erosion, protected with sediment trapping measures and located away from drain inlet, waterways, and drainage channels?
X
Have soils been stabilized at the end of the shift, before a holiday or weekend if needed based on the weather forecast?
X
6
Protect Slopes
Has stormwater and ground water been diverted away from slopes and disturbed areas with interceptor dikes, pipes and or swales?
X
Is off-site storm water managed separately from stormwater generated on the site?
X
Is excavated material placed on uphill side of trenches consistent with safety and space considerations?
X
Have check dams been placed at regular intervals within constructed channels that are cut down a slope?
X
7
Drain Inlets
Storm drain inlets made operable during construction are protected.
X
Are existing storm drains within the influence of the project protected?
X
8
Stabilize Channel and Outlets
Have all on-site conveyance channels been designed, constructed and stabilized to prevent erosion from expected peak flows?
X
Is stabilization, including armoring material, adequate to prevent erosion of outlets, adjacent stream banks, slopes and downstream conveyance systems?
X
9
Control Pollutants
Are waste materials and demolition debris handled and disposed of to prevent contamination of stormwater?
X
Has cover been provided for all chemicals, liquid products, petroleum products, and other material?
X
Has secondary containment been provided capable of containing 110% of the volume?
X
Were contaminated surfaces cleaned immediately after a spill incident?
X
Were BMPs used to prevent contamination of stormwater by a pH modifying sources?

Control Dewatering
Concrete washout in designated areas. No washout or excess concrete on the ground.
X
Dewatering has been done to an approved source and in compliance with the SWPPP.
X
Were there any clean non turbid dewatering discharges?
X
11
Maintain BMP
Are all temporary and permanent erosion and sediment control BMPs maintained to perform as intended?
X
12
Manage the Project
Has the project been phased to the maximum degree practicable?
X
Has regular inspection, monitoring and maintenance been performed as required by the permit?
X
Has the SWPPP been updated, implemented and records maintained?
X
13
Protect LID
Is all Bioretention and Rain Garden
Facilities protected from sedimentation with appropriate BMPs?
X
Is the Bioretention and Rain Garden protected against over compaction of construction equipment and foot traffic to retain its infiltration capabilities?
X
Permeable pavements are clean and free of sediment and sediment laden-water runoff. Muddy construction equipment has not been on the base material or pavement.
X
Have soiled permeable pavements been cleaned of sediments and pass infiltration test as required by stormwater manual methodology?
X
Heavy equipment has been kept off existing soils under LID facilities to retain infiltration rate.
X
