1. Registration/Information Posting | 2. Stormwater Appearance

1a. Is the registration/permit/ID number clearly visible at site entrance?:

1b. Is contact information posted with the registration information?:

1c. Is the site plan posted at the entrance or available at the project trailer?:

1d. Comments:

Board at site construction entrance was empty of all information. Did not otherwise enter site.

2a. Is sediment-laden stormwater retained on the site?:

2b. Is sediment-laden stormwater prevented from entering a storm drain or waterbody?:

2c. Comments:

During storm on 5/17 observed sediment leaving site at construction entrance and directly entering street storm drain adjacent to site entrance on Forest Pines Dr. Returned to site 5/18 with camera to document area. Site crew had already cleand sediment in street and drain (appears to have been washed away due to lack or soil residue), but evidence remained that sediment left site (remaining sediment on sidewalk, on top of storm drain curb cover, in street gutter downgradient of entrance) and entered storm drain on Forest Pines Dr.

3. Construction Entrance/Exits | 4. Perimeter Controls

3a. Is there enough stone, gravel, or stabilizing material to cover the entrance/exit?:

3b. Are construction materials and equipment being stored away from the entrance/exit?:

YES

3c. Is the road free from dirt tracked from the site?:

3d. Is the construction entrance/exit free from flowing dirty water?:

3d. Comments:

Observed sedimnent leaving site at construction entrance during the 5/17 rains. Stone appears long enough, but appears clogged. Sediment left site along down gradient side of entrance stone. (see #2 above)

4a. Are perimeter controls present?:

YES

4b. Are the controls properly placed?:

4d. Is water prevented from flowing over, under, or around controls?:

4c. Are the controls properly trenched?:

4e. Are the controls in good repair?:

4f. Comments:

Construction entrance is near lowest point of the site perimeter and is in path of site run-off. Sediment controls at this location were inadequate. Silt fence surrounds site but is in various states of disrepair. Original silt fence at north end of site is filled on site side and a second fence was installed along the top of the original silt fence. Original silt fence along Green Elm Ln. (north side) has deteriorated in areas. There may be an inpromtu site entrance on Common Oaks Dr. (south east side of site) but there is no stone or other controls. Just to the south of this location (south east corner of site) is a small sediment trap that appears overwhelmed. Adjacent downgradient silt fence is full of sediment and there may be a gap in the fence where sediment can escape. South side of site was generally unobserved due to vegetation. Did not enter site to inspect closer.

5. Storm Drain and Inlet Protection | 6. Soil Stabilzation and Cover

5a. Are storm drains and inlets protected and in good repair?:

5b. Are storm drains and inlets free from sediment?:

5c. Comments:

Storm drain at site construction entrance was cleaned ater 5/17 storm, but still shows signs of sediment. Inside the storm drain box there is a surface drain pipe that empties into this strom drain. Sediment is observable in this pipe. This pipe appears to come from a site inlet situated within the construction entrance stone area. The inlet appears to be surrounded with silt fence but sediment in outlet pipe indicated sediment is nopt being controled.

6c. Are soil stockpiles properly seeded, covered with tarps, or surrounded by silt fence?:

6d. Is the site free of rills or other major erosion on slopes or soil stockpiles?:

7. Sediment Traps, Check Dams and Basins

7a. Are sediment traps, check dams, or basins installed?:

YES

7d. Is the trap or basin retaining sediment?:

7e. Comments:

trap at SE corner of site along Common Oaks Dr appears to not control sediment. Basin south of site could not be clearly observed. Basin at NW corner of site should also be inspected.

8. Outlet Protection | 9. Encroachment on Waterbodies

8c. Comments:

requires futher inspection

9a. Is vegetation adjacent to waterbodies intact?:

YES

9c. Comments:

requires further inspection

10. General Comments:

Given the observed sediment discharge, official inspection and review should be performed.
