If the seed is mixed onthe site, each variety shall be delivered in the original containers which shall bear the dealer's guaranteedanalysis. If the seed is mixed by a dealer, the Contractor shall furnish the Engineer the dealer's guaranteedstatement of the composition of the mixture. Seeding shall be performed only during the periods of April 15 toJune 15 and August 15 to September 15. Immediately following seeding, the seeded surface shall be mulchedwith straw or hay free from weeds and coarse matter at a rate of 70 to 90 lbs/1000 sq.ft. Mulch shall beanchored immediately after spreading by application of liquid mulch binder or mulch netting applied inaccordance with the manufacturer's recommendations.

6. MAINTENANCE OF EROSION AND SEDIMENT CONTROL MEASURES

During the period of construction, all erosion and sediment control measures shall be inspected weekly andafter each rainstorm and during a major storm event. Accumulated deposits of sediment and silt shall beperiodically removed from the upstream side of the erosion and sediment control barriers, and uponestablishment of permanent seeding and mulching. Such materials removed shall be spread and stabilized innon-wetland areas which are not subject to erosion, or which are not to be paved or built upon. Haybales, siltfencing and other erosion and sediment control measures shall be repaired, cleaned, and/or replaced asnecessary throughout the construction period in order to maintain complete and integral erosion and sedimentcontrol protection. Once in place, all erosion and sediment control facilities and measures are to remain in placeand in proper condition and be continuously maintained until final grading has been completed, all disturbedareas upgradient of said facilities have been permanently stabilized and all newly grassed areas have had atleast two mowings. Following such permanent stabilization, the facilities shall be dismantled, removed, anddisposed of in an approved manner. Additional erosion and sediment control measures beyond those shown onthe plans or prescribed herein shall be put in place, whenever necessary, to address field conditions and/or asordered by the Town.A stockpile of excess erosion control measures shall be maintained on site at all times. Stockpile materialstored shall be covered and consist of jute mat, straw wattle and other materials as specified by the town andor engineer.

7. RESPONSIBILITY FOR IMPLEMENTATION OF EROSION AND SEDIMENT CONTROL PLAN

The Town's selected contractor shall be personally responsible for implementing this erosion and sedimentcontrol plan and enforcing the prescribed erosion and sediment control safeguards during the constructionperiod. This responsibility includes the installation and maintenance of control measures throughout theconstruction period, informing all parties engaged on the construction site of the requirements and objectives ofthe plan, notifying the proper Town agencies and officials of any transfer of this responsibility, and conveying acopy of the erosion and sediment control plan if the title to the land is transferred.The Contractor is responsible for monitoring weather forecasts to prevent work from occurring during periods ofhigh brook flow.

1. EROSION AND SEDIMENT CONTROL PROCEDURES

Protective erosion and sediment control measures, as indicated on the plan, shall be put in place for the project.Once in place, all erosion and sediment control measures shall be continuously maintained throughout theremainder of the construction period. In general, erosion and sediment control measures shall be put in place priorto disturbing the land. After installation of the initially prescribed measures, additional measures may be required toaddress field conditions as ordered by the Town of Needham or its designated agent(s). Limit of work will bedefined by the staked haybale and silt fence down slope of the construction.

A) Install staked geotextile silt barrier fencing downslope of proposed construction activities and/or acrossnatural and temporary drainage paths, prior to beginning any construction activities or disturbance of the existingsoil on the lot.

B) Install staked haybale and/or silt fence perimeter barrier around ballast, topsoil, and subsoil stockpilearea(s) if stock piling is done on site.

2. LAND DISTURBANCE

Insofar as possible, disturbance of the land shall be limited to the minimum amount necessary to complete theproposed work Interim or permanent stabilization measures shall be instituted on a disturbed area as soon aspracticable but no more than 14 days after construction activity has temporarily or permanently ceases on thatportion of the site. All trees and shrubs shall be conserved except those whose removal is required to perform theproposed work. The limits of disturbance shall be established in the field prior to starting any actual constructionactivities and shall be generally as shown by the topographic/site development plan drawings.

3. SEQUENCE OF CONSTRUCTION

The first construction operation to be performed after installation of the initially prescribed erosion and sedimentcontrol measures shall be the construction of the drive in access to the site which shall include the clearingobsticals and protecting the ground vegetation cover from eroding.

A) Any ballast or topsoil removed shall be stockpiled in a location outside the wetland resource area, andringed with a protective haybale/silt fence barrier for erosion and sediment control, as described above.

B) Construct and install drainage pipe. Grade rear of property and stabilize slopes up gradient of the wetlandresource areas.

C) Fine grade and permanently stabilize disturbed areas (Depending upon scheduling, construction accessconsiderations, or other site requirements, it may be necessary and/or feasible to change the order of the abovesteps.)

4. EARTHWORK OPERATIONS DURING CONSTRUCTION

Grading taking place as the site is excavated and filled shall be done in a manner to allow drainage towarddiversion ditches and erosion and sediment control barriers. Haybale or silt fence erosion and sediment controlchecks shall always be placed immediately after a cut slope has been graded and before a fill slope has beenmade. Concentrated runoff shall not be permitted to overflow newly graded areas, haybale barriers, silt fences orother erosion and sediment control measures.

5. STABILIZATION

All disturbed soil areas surrounding the wetland resource areas shall be fine graded and permanently stabilized, asdetermined by continuing construction activities or the season. All disturbed areas, regardless of their location onthe site, shall be fine graded and stabilized as soon as practicable following substantial completion of proposedconstruction.

A) Where seasonal conditions exist that prevent the establishment of vegetation or as required by theengineer or conservation commission, “JUTE MATTING" shall be installed on disturbed areas around the resourcearea.

B) Where a permanent seedbed is to be established, there shall be a minimum depth of 4 inches of topsoilspread, fine--graded and raked to remove large stones and other debris.

GENERAL STONE WALL INSTALLATION PROCEDURE

STEP 1: SITE ACCESS1) THE TOWN OF NEEDHAM WILL OBTAIN ACCESS (ENTRY PERMIT) TO THE JOB SITE. CONTRACTOR WILL NOT BE ALLOWED IN THE JOB SITE WITHOUT ENTRY PERMIT.2) CONTRACTOR SHALL SUBMIT A LIST OF EQUIPMENT TO BE USE AT THE JOB SITE FOR APPROVAL. NO EQUIPMENT SHALL BE USED WITHOUT APPROVAL.

STEP 2: PREPARE SITE1) REMOVE OF SEDIMENTATION ALONG PROPOSED WALL RECONSTRUCTION/ REPAIR AREA.2) INSTALL SEDIMENTATION/EROSION CONTROL MEASURES AND GRAVITY BYPASS PIPING AS REQUIRED.3) REMOVE INVASIVE SHRUBS AND TREES IN COORDINATION WITH CONSERVATION COMMISSION.4) REMOVE AND DISPOSE ALL SURFACE VEGETATION, DEBRIS, AND ORGANIC MATERIAL. THIS MATERIAL SHOULD NOT BE USED AS STRUCTURAL BACKFILL.5) EXCAVATE SITE SOILS AND PORTION OF THE FAILED WALL TO ALLOW FOR PLACEMENT OF STONE AND SOIL REINFORCEMENT.6) SALVAGE EXISTING STONE IF POSSIBLE AND REUSE TO REPAIR WALL SECTIONS. UNUSED STONES TO BE REMOVED AND DISPOSED OF BY THE CONTRACTOR.

STEP 3: BASE TRENCH EXCAVATION AND CONSTRUCTION PROCEDURES

1) EXCAVATE THE BASE LEVELING PAD TRENCH. THE TOP OF LEVELING PAD MUST BE A MINIMUM OF 12” BELOW FINISHED GRADE.

SEDIMENT REMOVAL MAY REQUIRE THE WALL EXTEND MORE DEEPLY AS DETERMINED BY ENGINEER.

THE BASE TRENCH SHOULD BE WIDE ENOUGH AS INDICATED ON THE "STONE WALL REPAIR CROSS-SECTION" DETAIL TO

ALLOW FOR THE STONES AND FILL ZONE.THE BASE TRENCH SHOULD BE A MINIMUM OF 18" WIDE FOR 12" TO 15” STONES.

THE BASE TRENCH MUST BE DUG DEEP ENOUGH TO ALLOW FOR PLACEMENT OF THE BASE LEVELING PAD. LEVEL AND COMPACT

SOILS IN THE BASE TRENCH PRIOR TO INSTALLATION OF THE LEVELING PAD.

2) THE NUMBER OF BURIED COURSES OF STONE WILL BE 1-2 (12” TO 15" STONES) UNLESS OTHERWISE SPECIFIED BY THE ENGINEER.

THE COMBINED DEPTHS OF THE BASE LEVELING PAD AND BURIED UNITS IS THE TOTAL DEPTH OF THE BASE TRENCH.

STEP 4: CONSTRUCT BASE LEVELING PAD

1) PLACE GEOTEXTILE FABRIC AND CONSTRUCT A 12" MIN. DEPTH OF 3/4” TO 1-1/2” CRUSHED STONE BASE FOR THE FULL LENGTH OF

THE WALL SECTION BEFORE STONES ARE INSTALLED.

2) PLACE CRUSHED STONE BASE LEVELING PAD MATERIAL AND COMPACT WITH APPROPRIATE EQUIPMENT TO ACHIEVE PROPER

DENSITY.

STEP 5: SET AND ALIGN THE BASE COURSE

ALL BASE COURSE STONES CAN BE PLACED FOR AN ENTIRE WALL LENGTH OR FOR A SMALL SEGMENT OF THE FULL LENGTH. TO

REDUCE THE MOVEMENT OF BASE STONES FROM CONSTRUCTION EQUIPMENT, PLACE UNIT DRAINAGE FILL MATERIAL AFTER

PLACEMENT AND LEVELING OF EACH TEN FOOT LENGTH.

STEP 6: PLACE UNIT/DRAINAGE MATERIAL

FILL THE STONE WALL VOIDS AND DRAINAGE ZONE WITH 3/4” TO 1-1/2” WASHED STONE DRAINAGE FILL MATERIAL. THE VOIDS ARE THE

OPENINGS AND SPACES BETWEEN THE STONE WALL. THE DRAINAGE ZONE IS THE COMBINED AREA OF THE VOIDS AND/OR

ADDITIONAL AREA BEHIND THE WALL.

STEP 7: POSITION AND SECURE CAP STONES

CAP STONES ARE TO BE SECURED WITH MASONRY MORTAR TO PREVENT THEIR REMOVAL.

STEP 8: FINISHED GRADE AND LANDSCAPING
