Check for corrections issued 9/28

Corrections in progress. RP on-site sweeping and monitoring work. Grading directs sheet flow to the west,not east towards Liberty so SF is no longer required along this perimeter. Excess dirt is to be removed this week.. DI bag has been installed and permit signs posted.

Will check back on Friday for futher compliance.

WIP on water and sewer line trenches. Silt fence has been trenched in and installed BMPs seemed to contain sediment on site during the last rain event. No new issues observed. Plans for retaining wall fix are in progress.

GC George onsite. Permit sign posted. No corrections at this time.

Ride along inspection of Harris Ranch North hillside grading & fill operations:

During the inspection of the upper section of the construction site I observed many BMPs in action as summarized below:

1. Dust suppression - water truck circulating on the main road from the site entrance, offices and staging area to hillside area. Road was not dusty due to moisture but was also not muddy, . Dust suppresion and compaction water for hillside work is stored in temporary lined holding pond at top of main entry road. Water pumped up from Penn. Canal. Large water buggy (9000 Gal) carries water to operations area as well as water trucks. There were no significant dust plumes observed.

2. Cut-slope faces and parcel stabilization & erosion and sediment control BMPs: slopes have been compacted and tracked horizontally. Sediment troughs have been created by earthen berms to contain/direct runoff. No rills or gullies observed throughout site. Slopes will be stabilized with combination of mats (coconut, jute) as well as bonded fiber matrix (BFM) and a site specific seed grass mix for hydroseeding. Before this work is done, top soil that was collected and stockpiled earlier in grubbing phase will be redistributed to provide growing medium for new grass & vegetation. Wattles will be installed at 10 ft intervals by Syman Co. The cut slope stabilization activities are scheduled to begin early November.

View lot parcels graded to direct runoff sheet flow inward to roadbase instead of to the hillsides. Edges of lots have earthen perms for extra containment.

3. Surface water and perimter sediment controls:

Silt fence installed along Pennitentiary Canal as well as preserved banks. Silt fence installed at wetland/drainage interfaces in the area of operations for the United Water main line installation that will go up Council Springs. Crews onsite installing silt fence. Water line work to begin next week.

4. Staging area and material containment BMPs:

Dual lined fuel tank, designated storage areas with containers labeled and stored with secondary containment for spill protection. Vapor barriers have been used for lining. Staging area has rock tracking pad, no trackout to Barber Dr. occuiring, and SWPPP and Boise ESC permit information is posted. SWPPP located in job trailer.

Site is in good condition currently and no violations were observed. No complaints have been received by the ESC division. Approved.

Service station demolition complete. Site is now new drive thru coffee shop under construction. This permit closed, active work covered under ESC15-00260. No corrections at this time.

Work in progress on pool, pool patios and shade covers, driveway and landscaping. Main site permit is ESC14-00403. Pool permit is ESC15-00396. This permit is for the backyard construction for pool surroundings.

Fugitive dust from stone saw -cutting with no dust suppression water. Stonecutter stopped work upon request, I noted that the cutter had a water connection and asked to hook it up to a hose.

No other violations observed. Warning issued to workers to continue dust suppression. Also requested Noah from RCH control his crew's dust as well.
