Planning Board Plans
Case 1. Lot #9-A-1901+ 9-A-1902
Presenter: Joe Maynard of Benchmark Engineering
Kendall Pond Road & Magnolia Road
Lot Line Relocation Plan
These two parcels have been replatted, which necessitated a new subdivision review. The commission recommended the following:

• Wetlands will be flagged prior to construction and occupancy.
• A memo to homeowner will be sent by builder to notify owner of wetland restrictions.

Case 2. H&B Homes
Presenter: Joe Maynard of Benchmark Engineering
Hadleigh Woods Estates - Elderly Housing
Proposed Site Grading for Staging Area
Mr. Maynard asked if the Dredge & Fill letter from Conservation Commission had been sent. The Chairman, Mr. Finn and staff support Pat Kovolyan were excused for this meeting so Mr. Maynard was told to call the office on Tuesday, April 30 to check on the status. The area in question is lot 3-B-200. The staging area is not part of the Elderly Housing development site plan. The area in question is off Rt. 28. Five acres in total with two acres used to develop Bissell Camp Road, and an acre and one half used for stockpiling the gravel from blasting to create the road. Trees will need to be cleared from the 1-½ acres but the 50' buffer around the perimeter will remain intact except for the entrance. Four existing trees need to be removed and will be replaced with White Pine after construction is completed. Width of construction road is 16'; slope is ¾% at the beginning. Mr. Capron expressed concern that clearing this area would allow for an expansion of the housing project. Mr. Harvey (owner) explained that because the lot in question is not part of the current development a site plan would have to be presented for approval. He also stated his future desire to develop this land as zoned for Rt.28. Ms. Linowes suggested that the access road for the development could also be the development road to minimize clearing and blasting issues and that construction sequencing could eliminate the need for a staging site. Mr. Maynard stated that while Ms. Linowes' suggestion would require less blasting, NHDOT, and Mr. Turner would not allow for a road access in that location due to the intersection demands with Green Mountain Road. Blasting the 10-16 foot elevation to get to the sub base requires space to a large amount of room to store and process the rock that will be used for road bed and house foundation construction. Bissell Camp Road will be 24' wide and encroaches on the wetland for 1500 sq ft. After construction the area will be loamed and seeded. As far as sequencing was concerned, all the homes will be built simultaneously.

On review of the housing project itself, rocks will be placed along the edge of the WWPD, 4-5' in between, so that it will be protected from construction. Wells still need 48-hour test for volume. Currently the 50' deep wells are pumping at 100-125 gpm. Water pipe from wells to pump house will be in the WWPD and will require trenching. Internal pedestrian trail, 6-10' wide, included plans for a gazebo in the WWPD. The commission suggested that no more than benches be placed in the WWPD.

The commission recommended the following:

• Remove the gazebo from the proposed plan to be replaced by no more than benches.
• Note concern to Planning Board and Selectman over clear cutting and the loss of natural resources for stock piling and construction staging. Commission did not want a precedent to be set for future construction projects.
• Note concern for the destruction of natural ledge when natural grade across from Green Mountain is available.
• The Commission felt that Bissell Camp Road is ill placed and the development and the natural resources would be better served by moving the road to the construction entrance.
• The disturbance in the WWPD for trenching for the water line needs to be hay bailed and silt fenced from construction to restoration.
• Suggest the community well be tested for Radon. If no baseline exists in NH, please look to other states for baseline.
• Flag buffer limits so they are not violated during clear cutting and stockpiling.
• Request for a public pedestrian right-of-way along Flat Rock Brook in the NW section of the property

Case 3. Lot #11-A-161
8 Ledge Rd.
Postpone discussion until May 1 site walk with Planning Board.

Case 4. Lot 13-C-1 and 7-B-5
52 Searles Road/Sam Nassar Subdivision Plan
Presenter: Mr. Peter Zohdi of Herbert Associates
Preliminary review of new subdivision plans and Dredge& Fill permit for 1171 sq ft. of ditch along Gov. Dinsmore Road. The subdivision plans show 16 homes off two roads, Gov. Dinsmore and Mackintosh. Most discussion surrounded Lot#13-C-11 which is accessed by a long driveway off Stonhedge Rd. The driveway is 28' long and planned totally in the WWPD. The presenter stated that zoning allows for a crossing in the WWPD. Mr. Capron and the commission told Mr. Zohdi that the intent of the ordinance was to allow a reasonable crossing for access to a buildable lot not to provide for an extended driveway through WWPD to reach the only buildable area in that section of the development. Commission asked if the house could have access off Mackintosh Rd. After reviewing the plan the Commission offered the following suggestions:

• Mackintosh Road should be sized to the width of the existing Gov. Dinsmore, which is 20'
• Lot#13-C-11 is located on the edge of the WWPD and driveway access would require a 28' dredge and fill in a WWPD. Commission would not support a Dredge & Fill of this magnitude.
• Lot#13-C-11 has the home placed too close to the WWPD
• Lot#13-C-9 should be placed closer to the road
• Lot#13-C-12 has the house placed within the recommended 50' construction setback along the WWPD on 3 corners. The 50' setback allows access for construction vehicles without infringing on the WWPD.
• Pesticide test should be conducted on the soils due to years of use in agriculture.
• Pedestrian easement is requested along double stonewall in order to link Rockingham Trail to Old Gov. Dinsmore Rd.
• Stonewall preservation where road is proposed. If stones need to be removed for access purposes they should be piled on the side of the road to be used for stonewall repair or appropriate placement on the property.
• Reduce the size of the cul-de-sac circle from 80' to a circle that is appropriate to a 20-24' circle.
• Commission is concerned about the proposed use due to the proximity to the Aquifer Protection District.
• Recommend 50 year flood test due to excessive flooding along Rt.28

The Conservation Commission will discuss other issues after Planning Commission's Public Hearing.

Case 5. Rogers Garage Lot 13-B-1
Presenter: Heather Storlazzi-Ward
Members of the commission walked the property on April 22, 2002. This property is described as a valuable flood storage area along Rt. 28 and the last recharge area for water before the Salem city limits. Wetlands and wildlife exist on the property even though septics from past use are violating the wetland. 19 parking spaces are placed in WWPD. There are two existing roads that cross the wetlands and both are represented on the site plan, one paved to the south and gravel to the north. The gravel road will require 410 sq. ft. for the Dredge & Fill permit with 330 in length and 80 side slopes, existing culvert is 12". Current well is shared with abutting home. Road will be curbed and parking lot runoff will be directed to the holding basin. The property will be used for auto repair and maintenance. Failed septic system from former motel will be cleaned up. The Commission suggested the following:

• The owner needs to provide for wreck and auto parking in a way that prevents fluids from draining into the wetland. Where will wrecks and cars for maintenance be parked?
• Parking lot is currently placed in WWPD. The commission would like the parking area moved to the NE side of the property
• Oil Pump separator/grease trap needs to be piped out into a treatment swale
• Wetland is flagged but WWPD needs to be marked on parking lot to allow for construction perspective.
• Asphalt areas removed need to be seeded with wetland seed mix.
• Where will snow removal piles be placed? Commission is concerned about runoff to wetland.
• No salt used on parking lot and driveways due to close proximity to wetland.
• Failed septic system is to be cleaned up.

Church Road Culvert Replacement
Dredge & Fill
Presenter: Robert Phillips - Senior Project Engineer
The existing culvert under Church Road is under capacity. It is located in a flood zone and Aquifer Protection District. Culvert is designed for 50-year storm and designed to eliminate detention upstream. Historic Church Road culvert is to be preserved. Grass panel at inlet for pedestrian use. Rip-rap from wing walls, with loam and seed behind the wing walls. Rip-rap is necessary to prevent undermining of the road/culvert foundation. The culvert will be replaced with Conspan Archway 36'- 48' Sandbag construction will be designed to allow for the environmentally responsive water diversion during construction. 1500' of temporary impact over a 2-week period with no traffic disruption due to the proximity to Senior Housing. Worksite will be placed across Indian Rock Road behind Nesmith Library. Construction will take place in low-flow water months between August and September. Mr. Phillips requested a Dredge & Fill letter of support be sent to the state. Mr. Capron moved approval and Ms. Linowes seconded the motion. Passed Commission unanimously.

Request for reimbursement for Dianna Fallon in the amount of $34.00 for copying and laminating 4 wetland fine signs for Foster's Pond. Commission approved expenditure.
