Final stabilization of disturbed and graded areas shall consist of either sod or loam and seed. Loam shall be replaced at a minimum compacted depth of 4" where needed. A fertilizer mix shall be provided as follows: Fertilizer may be applied at the rate of 7.5 lb. per 1000 s.f. of 10-10-10 or equivalent with lime applied at the rate of 90 lb. per 1000 s.f. (or as suggested after soil testing). No nitrates or phosphorus shall be used adjacent to wetland areas. ; Seecimixes may vary within the site, but in general wIL11 conform with the following mixtures: Areas of low maintenance and areas within the town right -of - May shall consist of .45 lb . per 1,000 s . f . of Reed Canarygr ss and .10 lb.er 1 000 s.f. of Redto . Areas that antici to P P D maintenance within the privately owned areas shall consist of 45 lb. per 1,000 s.f. of kentucky bluegrass, .45 lb. per 1,000 e.f. of Creeping Red Rescue, and .10 lb. per 1,000 s.f. of Perennial Ryegrass. Disturbed areas shall be mulched after loaming and seedi Mulch shall consist of straw or hay at the rate of 90 lb. r 1,000 s.f. Said mulch shall be anchored when deemed necessey by Town Planning staff. Anchoring methods shall consist of mu h netting or an asphalt spray. Seed bed preparation will conform to the standards recommended by the Connecticut Guidelines for Soil Erosion wind Sedimentation Control Manual. Hydroseeding will be permitted where slopes are no steeper than 2' horizontally to l' vertically. Where hydroseeding is used, the above rates shall be increased by 10%. Recommended seeding dated for permanent vegetation shall e between April 1 thru June 15 and August 15 thru September 5. Temporary vegetative measures shall consist of an annual r perennial ryegrass with recommended seeding dates from March 1 thru June 30 and August 1 thru October 15. Responsibility for installation of the above Mork sh 11 belong to the individual lot owner. His contractor shall be the designated on-site agent responsible for ensuring to the t wn that actual measures taken comply with the certified plan. I Design Considerations - Sediment barriers (hay bales or filter fence) are intended to protect areas of one acre or less �nd accommodate "sheet flow" run-off. Max. slope behind the barrier is 2:1 and the max, slope length shall be 100'. Any barriers placed in small swales are not intended to receive flows eny greater than 1.0 c.f.s. Anticipated life expectancy of hay ba es is 2 months and 6 months for staked filter fence. I While significant effort has been made to anticipate eros on potential and location, expected unforeseen "problem" areas day develop. It is the intent of this plan to prevent and cont in erosion wherever possible. To this end, the contractor may fnd it necessary to install additional sediment barriers, cut- ff trenches, stone or earth berms to meet the intent of these pla s. DA TE' Inspection and Maintenance - All of the above measures shall be inspected on a weekly basis by the on-site agent . Inspection of control measures shall also be made immediately after any significant adverse weather c:nditions, If said control measures become non-functional, immi-diate action shall be taken to restore the effectiveness of sa.d measures. Should significant breach of wetland barriers -.ccur and result in deposition of sediment beyond said barrier, excess sediment shall be removed as directed by the Environmental Officer. All control measures shall be inspected for proper operation and replaced as necessary. In particular, the contractor sho.;ld try to identify potential problem areas prior to failure,. A few major problems are herein identified, but do not relieve- the contractor from addressing other problems or failures: 11ales displacement, undercutting of bales or fence, fence collapsing, tough fabric, run-off escaping around end of barrier, seclment build up behind barriers. Hay bales and silt fence shall have sediment remov`d before it builds up to half the level of thy? original barrier. All measures shall remain in place, in;ipected by th._ on-site agent, and maintained by the developer until the Environmental Officer is satisfied the associated site ha-; stabilized. TEMPORARY VEGETATIVE COVEt' INSTALLATION REQUIREMENTS Site Preparation Grade as needed and feasible to permit }e use of equipment for seedbed preparation, seeding, mul, application, and mulch anchoring. All grading should bre one in accordance with the measure for Land Grading. Install needed erosion control measures uch as diversions, grade stabilization structures, sediment basins and grassed waterways. Seedbed Preparation Apply limestone and fertilizer acco, r1t4 to soil test recommendations such as those offered k), Ff. University of Soil Testing Laboratory. Soil sample rra tors are available from the local Cooperative Extension See, ce Office. If soil testing is not feasible on small or var.- le sites, or where timing is critical, fertilizer may be a,, ied at the rate of 300 pounds per acre or 7.5 pounds per l .-) square feet of. 10-10-10 or equivalent.

A fertilizer mix sh,1 be provided as follows: 8/15 - 10/+ Fertilizer may be applied at the rate of 7.5 lb. per 1000 of 10-10-10 or equivalent with lime applied at the rate of 90 per 1000 s.f. (or as suggested after soil testing). No nitrate-cl 1.0 phosphorus shall be used adjacent to wetland areas. Seed mixes may vary within the site, but in general li conform with the following mixtures: Areas of low maintenance and areas within the town rigrt,of- way shall consist of .45 lb. per 1,000 s.f. of Reed Canary,,;i anis and .10 lb. per 1,000 s.f. of Redtop. Areas that anticinre maintenance within the privately owned areae shall consist of .45 lb. per 1,000 s.f. of kentucky bluegrass, .45 lb. per 1,000 .f. of Creeping Red Rescue, and 10 lb. per 1,000 s.f. of Perer I'i t l Ryegrass. Disturbed areas shall be mulched after loaming and see -11 __-ig. Mulch shall consist of straw or hay at the rate of 90 lb, per 1,000 s.f. Said mulch shall be anchored when deemed necessary by Town Planning staff. Anchoring methods shall consist of r,Alch netting or an asphalt spray. Seed bed preparation will conform to the standards recotr.mended by the Connecticut Guidelines for Soil Erosion and Sedimentation Control Manual. Hydroseeding will be permitted where slopes are no steeper than 2' horizontally t{ 1' vertically. Where hydroseeding is used, the above rates sham be increased by 10%. Recommended seeding dated for permanent vegetation shall he between April 1 thru June 15 and August 15 thru September 15. Temporary vegetative measures shall consist of an annual or perennial ryegrass with recommended seeding dates from Mari,tZ 1 thru June 30 and August 1 thru October 15. Responsibility for installation of the above work shall belong to the individual lot owner. His contractor shall be the designated on-site agent responsible for ensuring to the town that actual measures taken comply with the certified plan. Design Considerations - Sediment barriers (hay bales or filter fence) are intended to protect areas of one acre or less and accommodate "sheet flow" run-off. Max. slope behind the barrier is 2:1 and the max, slope length shall be 100'. Any barriers placed in small swales are not intended to receive flows any greater than 1.0 c.f.s. Anticipated life expectancy of hay belles is 2 months and 6 months for staked filter fence. While significant effort has been made to anticipate erosion potential and location, expected unforeseen "problem" areae may develop. It is the intent of this plan to prevent and contain erosion wherever possible. To this end, the contractor may find it necessary to install additional sediment barriers, cut -of f trenches, stone or earth berms to meet the intent of these plane. Inspection and Maintenance - All of the above measures shall be inspected on a weekly basis by the on-site agent. Inspection of control measures shall also be made immediately after any significant adverse weather conditions, If said control measures become non-functional, imme,.iate action shall be taken to restore the effectiveness of sail measures. Should significant breach of wetland barriers o :cur and result in deposition of sediment beyond said barrier, -excess sediment shall be removed as directed by the Environmental->tficer. All control measures shall be inspected for proper operation and replaced as necessary. In particular, the contractor shou'.I try to identify potential problem areas prior to failure,. A few major problenss are herein identified, but do not relieve the contractor from addressing other problems or failures: bales displacement, undercutting of bales or fence, fence collapsing, tough fabric, run-off escaping around end of barrier, sed_ment build up behind barriers. Hay bales and silt fence shall rive sediment removed before it builds up to half the level of the 3riginal barrier. All measures shall remain in place, iris,_.t>cted by th,: jn -site agent, and maintained by the developer unit h 1 the Envirt�,nmental 4Vofficer is satisfied the associated site has -Stabilized.
