D. Impact Justification and Mitigation
1. Avoidance and Minimization
1a. Specifically describe measures taken to avoid or minimize the proposed impacts in designing project.
Alternate routes were discussed with the Department of Public Safety, but any route acceptable would have to cross Stream 2 on the Approximate
Waters Map. Other routes off of the correctional facility were evaluated and they were found to cross other streams and/or wetlands. The road
crossing has been designed to cross perpendicular to the stream to minimize the length of impact.
1b. Specifically describe measures taken to avoid or minimize the proposed impacts through construction techniques.
The culvert will have a buried Invert to all stream material to accumulate within the culvert and provide aquatic transport. Skimmer sediment basins will
be instated at each quadrant of the culvert to treat runoff during construction.

NOTES:
1. PUT SILT FENCE OR TREE PROTECTION FENCE UP TO ENSURE
CONSTRUCTION ENTRANCE IS USED.
2. IF CONSTRUCTION ON THE SITES ARE SUCH THAT THE MUD IS
NOT REMOVED BY THE VEHICLE TRAVELING OVER THE STONE, THEN
THE TIRES OF THE VEHICLES MUST BE WASHED BEFORE ENTERING
THE PUBLIC ROAD.
3. THE CONSTRUCTION ENTRANCE MUST BE CONSTRUCTED WITH CLEAN
STONE (NO FINES).
Maintenance
Maintain the gravel pad in a condition to prevent mud
or sediment from leaving the construction site. This
may require periodic topdressing with 2—inch stone.
After each rainfall, inspect any structure used to trap
sediment and clean it out as necessary. Immediately
remove all objectionable materials spilled, washed, or
tracked onto public roadways.

PERSONNEL (LAND QUALITY SECTION) FOR AN INSPECTION IF A PERMIT IS ISSUED. IF A PERMIT WAS
ISSUED BY LAND QUALITY SECTION, THE OWNER OR ENGINEER CAN NOT PERFORM THE FINAL INSPECTION.
19. WHEN CONSTRUCTION IS COMPLETE AND ALL DISTURBED AREAS HAVE BEEN PERMANENTLY STABILIZED,
AND LAND QUALITY SECTION HAS GIVEN APPROVAL, REMOVE ALL TEMPORARY EROSION CONTROL DEVICES,
INCLUDING SEDIMENT PITS, INLET PROTECTION, AND GRAVEL CONSTRUCTION ENTRANCE. REMOVE AND
PROPERLY DISPOSE OF ACCUMULATED SEDIMENT AND DEBRIS FROM THE DEVICES AND STABILIZE AREAS
DISTURBED BY THEIR REMOVAL. DEWATER SEDIMENT PITS AND SEDIMENT TRAP BY PUMPING ANY WATER IN

1. Prepare soil before installing blankets, including any necessary application of lime, fertilizer, and seed.
2. Begin at the top of the channel by anchoring the blanket in a 6" deep x 6" wide trench. Anchor the blanket with a row of staples/stakes
approximately 12" apart in the bottom of the trench. Backfill and compact the trench after stapling. Apply seed to compacted soil and fold
remaining 12" portion of blanket back over seed and compacted soil. Secure blanket over compacted soil with a row of staples/stokes spaced
approximately 12" apart across the width of the blanket.
J. Roll center blanket in direction of water flow in bottom of channel. Unroll blankets with appropriate side against the soil surface. All blankets
must be securely fastened to soil surface by placing staples/stakes in appropriate locations as shown by manufacturer.
4. Place consecutive blankets end over end (shingle style) with a 4"-6" overlap. Use a double row 'of staples staggered 4" apart and 4" on center
to secure blankets.
5. Full length edge of blankets at top of side slopes must be anchored with a row of staples/stokes approximately 12" apart in a 6" deep x 6" wide
trench. Backfill and compact the trench after stapling.
6. Adjacent blankets must be overlapped approximately 2"-5" (depending on blanket type) and stapled.
7. A staple check slot is recommended at 30 to 40 foot intervals. Use a double row of staples staggered 4" apart and 4" on center over entire
width of the channel.
8. The terminal end of the blankets must be anchored with a row of staples/stakes approximately 12" apart in a 6" deep x 6" wide trench. Backfill
and compact the trench after stapling.

Baffle Maintenance
• Inspect baffles at least once a week and after each rainfall. Make any
required repairs immediately.
• Be sure to maintain access to the baffles. Should the fabric of a baffle
collapse, tear, decompose, or become ineffective, replace it promptly.
• Remove sediment deposits when it reaches half full to provide adequate
storage, volume for the next rain and to reduce pressure on the baffles. Take
care to ovoid damaging the baffles during clean out. Sediment depth should
never exceed half the designed storage depth.
• After the contributing drainage area has been properly stabilized, remove all

EX. CHANNEL
CONSTRUCTION
STEP 1: REMOVE BRANCHES AND LARGE ROCKS FROM AREA WHERE THE SAND BAGS WILL BE PLACED. INSTALL SANDBAGS UPSTREAM
AND DOWNSTREAM OF CULVERTS TO BE REPLACED, IF THERE IS STANDING WATER IN THE EXISTING CHANNEL.
STEP 2: LAY OUT THE IMPERVIOUS POLY -FABRIC LINER WITH THE CENTER OF THE LINER LOCATED UNDER THE CENTER OF THE SAND
BAG DIKE.
STEP 3: PLACE THE SANDBAGS TO THE DESIRED HEIGHT. THE DIKES SHALL HAVE A WIDTH SUITABLE TO SUPPORT THE HEIGHT. EACH
ROW SHALL BE OFFSET SO THE JOINTS ARE STAGGERED. PACK SANDBAGS TIGHTLY TOGETHER.
STEP 4: WRAP IMPERVIOUS POLY -FABRIC LINER AROUND SANDBAG DIKE AND SECURE WITH FINAL LAYER OF SANDBAGS.
STEP 5: PUMP OUT ANY WATER TRAPPED BETWEEN THE TWO SAND BAG DIKES.
MAINTENANCE
-PERIODICALLY INSPECT SANDBAG DIKE FOR DAMAGE AND LEAKS
-REMOVE IMPOUNDED TRASH AND SEDIMENT

2. INSTALL SAND BAG DIKES UPSTREAM AND DOWNSTREAM OF
EXISTING CULVERT. PUMP OUT ANY WATER TRAPPED BETWEEN
DIKES. IF THERE 1S ANY FLOW IN EX. CHANNEL, MAINTAIN A
BYPASS PUMP DURING INSTALLATION.
3. INSTALL STONE BASE, CULVERT, AND BACKFILL CULVERT.
