EROSION AND SEDIMENTATION CONTROL PLAN

1. Purpose and Description: This project contemplates the replacement of an old button factory that was previously located on the site with a new 14,280 square feet (including basement) mixed residential/commercial use building that will be compliant with the stated purposes of the Village Center District.

2. Site Characteristics: The site is comprised of 3,270 square feet of relatively flat topography. A five (5) feet passage way is envisioned for the south side of the building adjacent to an existing brick structure. The front of the building will abut the existing improved sidewalk configuration recently put in place by the Town of New Milford and will contain a landscaped planter. The north side of the building will abut an existing municipal parking lot. The rear of the building will abut the parking area for the Post Office on Main Street. The grade differential is approximately eight feet (8’) in height (front to rear lot line) with a five (5) feet retaining wall located approximately one hundred ten (110) feet from the front lot line. The slope from front lot line to this retaining wall is approximately three (3) feet, front to back. There are no wetlands on the site. The area of disturbance will be the footprint of the proposed building or approximately 3,000 square feet.

3. Erosion and Sedimentation Control Issues: These issues are relatively minor and consist of insuring that any sedimentation created during excavation remains on the site. Since the building footprint uses the majority of the site, site run-off is restricted to roof run-off and any direct rain run-off from the concrete passageway to be located to the south side of the building adjoining an existing building, both of which will be accommodated by the municipal storm sewer located in the front of the building. Effective use of siltation fencing and hay bales during construction would appear to be adequate enough to prevent any erosion or sedimentation control problems.

4. Construction Sequence:

a) Obtain all permits, notify applicable municipal officials, and notify “call before you dig” for utility mark-out.

b) Install sedimentation fencing as show on the applicable drawing.

c) Construct any required anti-tracking pads, especially if the adjoining municipal parking lot is used for access of construction vehicles.

d) Insure maintenance of installed devices.

e) Remove all brush and trees within the building footprint area.

f) Stockpile material for removal from site.

g) Excavate in accordance with building plans.

h) Connect water service, electrical service, sanitary sewer service, and storm sewer service and insure appropriate backfill.

i) Install front and rear landscaping.

j) Stabilize any remaining minimal slopes with seed, mulch and/or ground cover

k) Remove silt fencing and hay bales.

l) Insure any remaining areas are seeded/stabilized.

m) Insure all work, seeding and planting are in accordance with “Connecticut Guidelines for Erosion and Sedimentation Control – 2005” issued by the sate DEP.

5. Dust Cover: Since the total quantity of disturbance is relatively small and the period of construction is relatively brief, no exception measures need be taken. On-site water availability can be used, as necessary, to wet down any material piles. Trucks will be equipped with canvas covers. Anti-tracking pads will also be used to control both siltation and any dust emitted from excavation operations.

6. Sediment Barrier:

A. Sediment Fencing:

a. Material: Synthetic filter fabric shall be pervious sheet of propylene, nylon, polyester or ethylene filaments with 75% filter efficiency, tensile strength at 20% maximum elongation of 30-lbs/lin. in. (min) and a flow rate of 0.3 gallons/sq. ft./minute.

b. Installation:

i. Height shall not exceed 36”.

ii. Where joints are necessary they shall be spliced at post supports with a 6” overlap and securely sealed.

iii. Posts shall be located 10’ apart a sunk a minimum of12” into the ground.

iv. A trench shall be excavated approximately 6” wide and 6” deep along the line of posts and upslope from the barrier.

v. The filter fabric shall be securely fastened to the posts with staples, wire or ties and 8” of the fabric shall be extended into the trench. The fabric shall not extend more than 36” above the original grade surface. Filter fabric shall not be attached to trees.

vi. The trench shall be backfilled and the soil compacted over the filter fabric.

c. Maintenance:

i. Filter barriers shall be inspected immediately after each rainfall and at least daily during any prolonged rainfall and repairs made immediately.

ii. Any decomposed fabric shall be immediately replaced.

iii. Sediment deposits shall be removed when the reach approximately ½ of the height of the barrier.

iv. Any sediment deposits remaining in place after the removal of fabric barriers shall be dressed to conform to the existing grade and seeded.

B. Straw/Hay Bales:

a. Sheet Flow Application:

i. Bales shall be placed in a single row, lengthwise on the contour, with ends of bales tightly abutting one another.

ii. All bales shall be either wire bound or sting tied so that bindings are oriented around the sides rather than along the tope and bottoms so as to prevent deterioration of the bindings.

iii. The barrier shall be entrenched and backfilled. A trench shall be excavated the width of the bale to a minimum depth of 4”. After the bales are staked and chinked, the excavated soil shall be backfilled against the barrier. Backfill soil shall conform to the grade level on the downhill side and shall be built up 4” against the uphill side of the barrier. Ideally bales should be placed 10’ away from the toe of the slope.

iv. Each bale shall be securely anchored by at least two stakes or rebar driven through the bale. The first stake in each bale shall be driven toward the previously laid bale to force the bales together. Stakes or rebar shall be driven deep enough to securely anchor the bales.

v. The gaps between the bales shall be chinked with straw to prevent water from escaping between the bales.

vi. Inspection shall be frequent and repairs made immediately.

vii. Bale should not be removed before the upland areas have been stabilized.

b) Channel Flow Applications:

i. Bales shall be placed in a single row, lengthwise orientated perpendicular to the contour, with ends of bales tightly abutting one another.

The remaining steps are the same as in Sheet Flow applications above. Except that the barrier shall be extended to such a length that the bottoms of the end bales are higher in elevation than the top of the top of the lowest middle bale to insure that sediment laden runoff will flow either through or over the barrier, but not around it.

c) Catch Basin Applications:

i. Bales shall be placed in a square or rectangle around

depressed catch basin inlets. Catch Basin constructed on

sloping areas shall not be encircled by bales.

ii. The areas around a catch basin may be excavated

slightly to increase ponding of runoff water around the

catch basin.

iii The remain steps per Sheet Flow applications apply.

d) Maintenance:

i. Inspection shall be frequent and repairs or replacements

made immediately. The barrier shall be removed when

it has served its purpose so as not to block or impede

storm flow or drainage.

7. RIP-RAP & TEMPORARY PLANTING; Construction on the site does not perceive the need for rip-rap and the brief period excavation does not warrant the need of temporary plantings.

8. PERMANENT PLANTING: Landscaping is limited by site condition to the use of planter boxes in the front of the building and seeded or ground cover in the rear of the building. Plantings/trees to the upland area behind the rear stonewall will remain undisturbed.
