Subdivision BMPs installed. WIP on SFHs. No significant loose dirt in streets and gutters, no discharges, no fugitive issues at time of inspection.

Hauling stockpile in previously graded area to Parckcenter roundabout.

No water truck on site for dust control. Conditions areagetting dustier with use and heat.
Requested water truck be onsite to wet down haul road ASAP. RP stated water truck was enroute. C & A paving was alson contacted.

East Valley subdivision has individual SFHs in progress. First round on Sky Bar is near completion.

All stormdrains have inlet protection, fiber wattles are installed at areas where sheet flow caused sediment runoff to streets. Sediment trench and berm has also be excavated to trap and retain sheet flow onsite. Lined concrete washout is being used and trash is contained in bins.

Silt fence is incorrectly installed but is being used as a construction fence to prevent vehicle traffice across landscaped area.

No corrections at this time. But will need Ground FX / Conger remove the discarded wattles.

East Valley BMPs have been repaired and a new lined concrete washout provided. Workers and material delivery vehicles staying off muddy open areas.

Inspected East Valley sub to see if BMPs withheld the siginificant amount of rain received earlier today.

Compost wattles and trench with berms built in low discharge area have worked effectively. No blows out muddy running into the storm drain (which is also protected).

Tahoe Homes contractors doing well to stay off the open areas to prevent trackout.

Lined washout installed is near full and needs replacement.

East Valley sub is in good condition. No new erosion rills on hillsides and banks observed. Lined concrete washout, drop inlet protection, and fiber wattles at discharge/low points have been installed.

1 correction:

Clean out inlet protection mat and dirt on gutter and street at the southwest corner where fiber wattles have been overwhelmed. Need to consider installing additional BMPs here,such as a silt fence.

East Valley sub drainage design and sediment control BMPs were effective in preventing sediment runoff from open areas and SFH sites during the last 2 two days of precipitation.

DIs have coir mat protection. Some minor trackout on roads, but contractors are staying off dirt and parking on street. Lined concrete washout in good condition. No discharges or other ESC issues observed at time of inspection. Still working on the sewer lift station on the south west corner.

Limited activity. SFH homes in progress by Tahoe Homes. No runoff issues yet, still froxen.

East Valley subdivision now has individual homes being built. No major trackout, discharges, dust or other issues observed. Fiber wattles have been installed in areas where sediment ran off lots in the last storm event and all stormdrain DI's have filter protection. No corrections at this time.

Site observations:

No trackout to Warm Springs, All DI to seepage system have silt bag protection. Perimeter fiber compost/bark wattles line many areas.

Issues: landscapers have removed some wattles to park on dirt and our causing trackout within the subdivision. Wattles have also been driven over in some areas that could cause blowouts.

Recommended to RP Conger that they may want to install check dams and that he should monitor the weather and make corrections prior to next storm. 40 % chance of rain forecasted for Sunday 9/21....

Only minor activity at East Valley at time of inspection. No dust, no trackout, or other violations observed.

Additional Filtrex wattles are installed and streets are mostly clean from previous washout/blowout. DI bags were maintained and have remaining capacity. Approved.

Internal work SWO. Met Jim Conger onsite along with Ground FX to correct BMP Violations (No Perimeter Controls Installed, Large Amount of sediment left interior site, filled Drop Inlets,
Excessive Sediment Running over sidewalks and roads, along with flooding out a neighbor business with mud and water. Conger is bringing in extra crews and equipment to begin cleanup and repairs to adjacent business, to address violations imediately.
CLEAN UP HAS BEGUN

Site has one water truck that is still filling up at Dallas Harris #12 so there is some lapse time when truck is at site. Haul road and area where dirt is being loaded has be wettened, but need to increase spray on Warm Springs east of entrance. Talked to water truck driver Ross who said he will extend his spray.

Corrections:
1. RP has ordered street sweeper for this evening (end of day)
2. Knife River will turn over/refresh construction entrance/tracking pad.
3. Trans Systems drivers need to slow down.

Dust check up.

Trucks are driving much slower and the mag chloride is also helping keep dust down. The water truck comes 1x per hour, may need to increase as day continues.

Unrelated to dust, need to install storm drain filter bags at entrance on Sky Bar. RP has been notified.

SWO corrections have been addressed.

Corrections made:
1. Magnesium chloride dust suppressant has been applied on the entire loop of the haul road to and from Warm Springs to stockpile area.
2. Water trucks will be used 1 x per hour and will increase as necessary.
3. At time of inspection no dust created by truck traffic.
4. Mr. Conger stated Warm Springs will be swept at end of the day in front of East Valley and Harris Ranch.

Approved to continue work. Will check in later today when conditions are hotter and drier to see if mag chloride is effective.

Returned to site to find no corrections or effort at dust control.

Issuing Stop Work Order with corrections.

Underground utilities have been installed, roads paved, and curbing installed. No dust issues, trackout, or illicit discharges observed at time of inspection.

Underground utilities in first East Valley Sub have been mostly installed. Starting work on the roads , gutters and sidewalk. Permiter wattles line Warm Springs. Construction entrance rock is piled on site, but the entrance has not been installed. No trackout issues apparent at site. Will continue to monitor. No dust seen crossing Highland Valley Road or Warm Springs. No corrections required at this time.

Discussed East Valley sub development with RP Jim Conger after he returned my call from earlier.

Water trucks were on site, but not in use at time of inspection. Some dust, but not visibly crossing project area. Told Brown Construction employee to slow down while driving big tractor, to which he agreed. Discussed dust control practices that will be implemented during more activity

Large stockpile at north end of site is currently in use for active utility work and grading. Some portions have naturally vegetated. The dirt is potentially going to be used at new Harris Ranch phase currently under review. If stockpile is inactive for more than 2 weeks at a time, tacifier/mulch will be used to stabilize. The pile was tacified once earlier in the year according to Mr. Conger.

Offsite utility project (ESC14 -00238)is currently on hold but should resume next week in coordination with new Brighton Homes project.

No recent citizen complaints brought to my attention.

Corrections:

1. Install main construction entrance per SWPPP and restrict access in other areas that have been used by different contractors.

2. Ensure dust controls are in place in future phases.

No new violations. Still need to confirm status of stockpile from intial hill cutting. It has been inactive for some time and not stabilized.

jim Phone #: ###-####

SWPPP and ESC permit posted onsite. Perimeter wattles have been set in place, but rock construction entrance is not yet installed. No surface waters or creeks running through site, which is also relatively flat.

Will need to watch dust once the vegetation is disturbed. When stockpile hauling begins, a heavy duty construction entrance will be necessary.
