Director Babin stated the purpose of the public meeting to present plans for the proposed substation to be located on Bird Rd. A detailed design of the proposed substation and its immediate surrounding area is to be presented for public comment. Questions and comments from interested parties after invited after presentations are concluded. He then introduced Mr. Alan Rice of PLM. Mr. Rice is the Design Engineer that would be discussing the detailed plans for the proposed Bird Rd. project. Director Babin also introduced Cheri Ruane from the landscape architecture design firm Westin & Sampson. Director Babin explained that Westin & Sampson's role has been to work with both PLM and the four abutting residents to try to accommodate the exterior design of the station to what is acceptable to the residents. Director Babin explained that a couple weeks prior to this evenings MMED, PLM, and W &S met with the four abutting residents to go over potential approaches to the exterior design of the proposed substation. Director Babin recapped the proposed project. It has been in the works since 2004. In 2007 PLM did a planning study to determine the projected town growth and power requirements for future years. PLM focused on five sites in East Mansfield to satisfy these projected needs. Later this optimum site was narrowed down to the parcel 39-38 just off Bird Rd. Last July the Board authorized the staff to proceed with the permitting of that particular site, as well as enter into discussions with National Grid, the current owner of the land, with the intent of constructing the proposed substation. April2ih is the proposed date to take tonight's plans to the Conservation Commission and have a Notice ofIntent Public Hearing. For the 2ih National Grid will need to authorize the filing. Director Babin indicated that they are working together on getting that taken care of. A target date of April 29th would be set for the Planning Board Site Plan Review, a.k.a. A Municipal Clearinghouse Review Public Meeting, for the Planning Board to review the site plans. Director Babin stated that should the Conservation Commission and the Planning Board both approve the site plans MMED would then be able to begin the construction process. A request for bond authorization to provide funding to build the station would be presented at Town Meeting in May 2009. The warrant article is for a figure not to exceed $8 million. If the bond is authorized the next step would be to order the equipment in the Fall of 2009 with a delivery date ~ about 1 year. Site work and electrical construction would begin in the Summer 2010 working right through to Winter/Spring 2011 with a projected in-service date Spring/Summer 2011. Vice Chairman Aptowitz questioned Director. Babin if there are some financing scenarios for the Fin.Com. to review. Director Babin said that he had met with the town's banker that they use for bond authorization earlier that day. He was there to go over the bond language with the attorney and had spoken with Jack Goldberg about the numbers for the project. The initial projection was based on a $6 million borrowing at 4% which would be equivalent to $15/yr for the average resident and decline from there. It started at $15 per year and went down to about $13/yr over a 20 year period. Commissioner Dentino had a question regarding the scheduling of the April 29th Planning Board meeting. If the Town Meeting authorizes the bond, why would the site work need to wait until the following Summer to begin? Director Babin explained that it takes approx. a year for the equipment to be manufactured and delivered so the site construction would begin shortly before that in the Summer 2010 to prepare for delivery in Fall 2010. Alan Rice from PLM explained that the entire process takes approximately 18 months total from the time of the original order to the station being online. This is because each project is conformed to meet the individual needs and specifications. Director. Babin said that the focus has been on the Site Plan review and meeting the requirements for that. He said that MMED has sat down with Sean Burke at least two or three times and continued to "keep him in the loop" throughout the process. Director Babin also said that they are preparing the necessary documents for the Site Plan Review. If authorized MMED would then they would work on far more detailed drawings and designs. Director Babin explained that it is a process that would not be best to start and stop, that continuity would be beneficial since you would not want to start the construction then stop to wait for delivery then begin construction again. It would be best to wait to coordinate site work so that it is completed before the equipment delivery in conjunction with the equipment delivery date. Also, from a banker's standpoint, you would not want to borrow money before you actually need it. It would be best to time the borrowing with the need for the cash flow. Commissioner Dentino again questioned the timing of the order/delivery. Alan Rice then said that the order date would be closer to mid-Summer 2009. Commissioner Dentino wanted to know what equipment is required besides the transformers. Alan Rice said that the transformers are traditionally a one year delivery. That doesn't include the procurement process which is actual advertising, bidding, awarding, and so forth. That process can run more like 14 months. The switch gear building is also a long lead time, closer to 9 months or so. Substation structures and bus work are about a 7 month lead time. Alan explained that everything is done based on delivery dates so that the equipment shows up at the right time and the contractor can complete the work in the most efficient way. Alan explained that the structure is a factory fabricated enclosure that will be delivered in sections and placed on the foundation and joined and wired on site. The equipment is placed in the building at the factory. Commissioner Dentino asked if the enclosure is metal and Director. Babin acknowledged that it is. Commissioner Dentino asked if the neighbors were OK with that. Mr. Rice then indicated that that is what they are here to talk about tonight. Commissioner Dentino then stated that he was surprised that to hear about the meeting with the neighbors. He said he didn't know anything about the meeting, didn't know what the neighbors suggested, and didn't know what MMED incorporated into the plans. Commissioner Dentino was also under the impression that the building had veneers. Director Babin explained that is why they are all there. They are there to put forth a proposal and if the Board doesn't like what they hear they can say no and can send the staff back to the drawing board. Chairman Baldwin asked if Director. Babin was looking for a vote and he said that they were coming to the Board with a proposal. They had met with the four abutters with a direct visual line to the site but not all of the residents from the area. There were no drawings at the time, just questions to see what the residents would prefer for a landscape plan. Director Babin asked Commissioner Dentino to reserve judgment until MMED had made its presentation. Alan Rice then began the presentation. Alan works for PLM Electric Power Engineering and has done a couple of other presentations here before. He had presented a planning study, the feasibility study and he currently is working on a design for the site that was selected for the substation on Bird Rd. He said that the site on Bird Rd. is both a good site and a difficult site. The site is smaller than ideal but the location has some advantages with the proximity to the right-of-way. Mr. Rice then presented some photographs and drawings of the parcel to show where the various property lines are and the proposed substation site in regards to the surrounding area. Since the parcel of land is owned by National Grid there are some limitations. MMED cannot obstruct National Grid's access to the transmission lines within the corridor. MMED is very limited in placement of equipment, fences, etc. on the NG right-of-way. MMED is able to place a driveway on this property, but not able to place any buildings or any portion of the secure substation yard that will contain any MMED equipment. Mr. Rice stated that there is a wetland immediately into the rear of the parcel and we have to minimize any impact to that area. Mr. Rice stated that the proposal was not to do any construction or change the grade of the land within 25 feet of the wetland and also to create a reliable and secure facility for the Light Department. Mr. Rice also explained that the substation needs to be able to house two transformers in case of a power outage, the second unit needs to be able to carry the load while the first is out of service or having maintenance work done. The substation also needs to be able to accommodate two transmission sources. The one that exists from the South direction is from Easton; the other line will come at some point in the future, most likely from Foxboro because Patriot Place is driving development there. The circuits will come out of Bird Rd. underground so there will be no change in the appearance of Bird Rd. as you drive down. Mr. Rice explained that National Grid has a large impact on what MMED does with respect to structure and design. There is a 300' wide corridor but we are limited to what we can do with that area. MMED is allowed to put a driveway and plans to put a fence around the facility with a gate for access, but cannot in any way limit the access for NG to access their equipment. Approximately 40' from the road will be a single story metal fabricated building at about 12'6" at its highest point. The conductors inside the station will be about 16' high. Mr. Rice showed " various views of the structure and the property and explained where they would be in relation to the surrounding property and National Grid structures. The existing National Grid transmission structures are about 80' high with another 20' static wire at the top. MMED's structure would be significantly lower. Mr. Rice also emphasized the thought that has gone into incorporating high function and minimal impact on the footprint. Due to the scale of the equipment and the space limitations it will not be feasible to have the facility resemble a house as had been previously discussed. Mr. Rice also addressed EMF and tried to place the structure as far away from property lines as possible. Historically, the Massachusetts Energy Facility Siting Board (EFSB) has required less than 85mG at the edge of the transmission line right-of-way. Calculations indicate that the magnetic field would increase from existing levels by less than 0.3mG at any of the abutting residential property lines. With superimposed .3mG onto the field measurements would still be less than 1 mG at the nearest residential property line. MMED is significantly below the threshold that EFSB have set. Mr. Rice then addressed the audio impact on the neighborhood. Power transformers will hum at 120 cycles and what is being proposed is to purchase transformers that are 10db below standard noise level. Every 3db of noise reduction reduces 50% decrease in noise. If MMED purchases transformers 10 db less than standard it will decrease noise by about 90% on the surrounding residents. There are also plans to install an internal sound barrier wall which will also help to mitigate the sound. In addition there are also plans to have a perimeter wall that will have sound dampening qualities. Mr. Rice continued to describe how the impact of the facility and its construction would be done to lessen the impact on the neighborhood and surrounding wetlands. The air conditioner units for the substation equipment housing would be programmed not to run during the evenings. The construction work hours would be limited to times to not cause a disturbance. The oil containment system would be designed to hold the entire volume of oil held in one transformer in the event of a catastrophic fault. No change of topography within 25' of the wetland to the rear would be done and also an underground storm water runoff management system would be installed that would be similar to a leaching system. He also stated compliance MMED would comply with the Mansfield Conservation Commission Order of Conditions. Security and lighting was also addressed with a non-scalable perimeter wall or fence, motion sensing lights, and monitoring the building through use ofthe existing SCADA system. The SCADA system can both monitor and record any information. The lights would be downward, low level, and partially screened by the perimeter wall to avoid disruption to the residences, but also bright enough to allow secure access for the personnel. That concluded the presentation from Mr. Rice. Next was Cheri Ruane, the landscape architecture, from Westin & Sampson. Her role is to help develop a visual and noise mitigation plan for the substation. Some of the critical that she wanted to address were the deer tolerance for plantings, height of plantings and also the National Grid requirements ofMMED. The structure needs to be non-scalable, non-flammable, and secure. These topics were discussed at the meetings with the three abutters. ." The adjacent wetlands are critical and prohibit pushing back too far into the overall parcel. W &S will be coordinating with the Conservation Commission to adhere to their requirements regarding non-invasive native species in the 100 foot buffer zone. Ms. Ruane explained that no vegetation can exceed the height of the perimeter wall for both safety and security. A 12' wall was what seemed agreeable in the meeting with the abutters. So at mature height nothing adjacent to the wall can be above 12'. The further you get from the wall the taller the plant material can get. Ms. Ruane had various drawings of the planned substation and its proposed plant material. There were lots of Spruce, Juniper, native species including witch hazel, bayberry, etc. The wall is proposed as a solid concrete wall with a cement fence at the top. The wall and fence would both serve as security, safety, and sound attenuating. It is also very low maintenance and breaking it up without giving it the prison fence look. The wall/fence would surround the entire substation with very low (1-2') plantings on the right side of the driveway to stabilize the slope and also hug the rest of the development. Ms. Ruane stated that W &8 is also working with the developer of Stanley Circle to come up with effective plantings. Along with the MMED plantings there will be planting on the abutters properties as well. Visual impact and blending in with existing species were also a concern for W&8. Ms. Ruane then went though more drawings of proposed planting views from different angles and views, including from the angle of a second story window of an abutters home. These drawings were also future scale drawings to show the plant growth. This concluded Ms. Ruane's presentation. Chairman Baldwin then opened for questions at the podium. The resident at 11 Allen Way questioned the elevation drop rate of a particular side. Ms. Ruane answered 4' due to the nature of the future Stanley Circle subdivision. He then asked how far above the water table is that 4'. Ms. Ruane said that it was not too much deeper to the ground water, given the surrounding wetlands. Mr. Rice then added that there will be some cutting into the banking along the front edge of the site and filling on the rear to make it close to a 206' final elevation for the station. Mr. Rice also added that Bird Rd. itself is around 208-210' elevation and standing water of the wetlands is 198' or so. Ground water comes up slightly under the site but he stated not to assume that we are not on top of ground water at 206'. Mr. Rice then addressed the driveway and transformer removal and/or installation. There would be special low trailers with 32 wheels to maneuver in and out. The driveway has minimal pitch with the Bird Rd. end at 208' and the substation at approximately 206'. He said it is quite manageable. A secondary concern is MMED vehicles getting stuck during a winter snowstorm because they can get in, but not back out again. This situation lends itself to the 4' cutting of the bank about 40' back so that the substation yard remain as level as possible. If the yard were to be depressed you might get the opposite effect from a higher view. It would be more like looking down and into a stadium instead of looking up and across. The resident from 50 I Bird Rd. also had a question regarding the actual height of the substation and the various views. Ms. Ruane then said that the roof is actually 8" above Bird Rd. from a drive/pedestrian point of view. ." The resident at 24 Bird Rd. then asked how the construction would actually affect Bird Rd. and the existing poles and the potential hazard of underground lines. Director Babin chose to address this concern. The poles will not be removed due to the other existing utilities on the poles. The underground cables for MMED to leave the station would be in an underground duct under the paved part of Bird Rd. Director Babin then asked Mr. Rice to address the EMF issue. Mr. Rice said that although the lines are closer there is a more direct cancellation of the magnetic field, but he did not have a definite answer because he did not have the analysis he had performed with him. The resident stated that there are quite a few children in that area and also voiced concern over access to the lines with the recent stories of electrocutions in Boston. Mr. Rice said that every 300-400' there would be a manhole for access; a pre-cast underground structure with a metal cover. These metal covers and everything within the manhole would be grounded. Mr. Rice then explained that during damp conditions, a large amount of conductors, as in large cities with a robust underground network, the equipment cannot detect a short circuit because of the way that it works. In MMED's case all of the cables will have a relay that will automatically detect a very small level of fault current and immediately turn off the circuit. Director Babin simply put it that MMED's equipment is going to be brand new, typically those situations happen in large, urban areas with older equipment that cannot detect the low voltage issue. Director Babin then proceeded to address the EMF issue. The EFSB standard is 8SmG at the edge of the right of way. With the analysis that was done, only ImG was detected at the edge of the road, which he felt was quite minimal. He stated you get more with a hair dryer next to your head. The resident requested that analysis info and Director Babin said that he would forward it to her. The same resident then asked for plans regarding the construction, the timeline and if the road was going to be torn up and patched or re-paved and if there will be more traffic. Director Babin said that yes, the traffic will increase due to the construction vehicles working in the road and at the substation. He assured her that Mansfield will perform a good repair job on the road and if the trench cut is clean that the road will certainly be as good, if not better than before the construction starts. The resident from 512 Bird Rd. then came to the podium and asked about the plantings. Who will be responsible in the case of a storm? Director Babin answered that MMED would be responsible for the plantings immediately adjacent to the substation; he was not sure about the plantings on private property. The same resident then asked if there was a similar substation nearby that could be driven by to check out the sound levels. Director Babin then said yes, in Raynham, off ofRt. 44. However, that one has more of the penitentiary look to it. Vice Chairman Aptowitz then said that he had been out to the Raynham substation and it sounded like a central air conditioner fan. Once he walked 20-30' away he could barely hear it at all, but the area is a little different, it is not residential - it's behind a shopping plaza. It's not the same, but you would certainly get a feel for what to expect. It's in Raynham and we could get you the location. Chairman Baldwin verified Director Babin had the residents name and contact information to get him the Raynham substation info. The next resident was from 12 Colonial Dr. He was concerned about the elevations of the building and the aesthetics of the building. Director Babin recalled that a gabled roof was ~ mentioned at one point, but nothing like that is available for the structure that MMED is considering and the criteria that it needs to meet. From the road that should not be a factor. Director Babin then indicated that if someone were at an elevation and looking down that it might become an issue. Once the plantings grow that view should be lessened as Ms. Ruane had stated. Both the resident from 12 Colonial and VC Aptowitz showed concern over seeing what the substation structure will look like. Mr. Rice then said it is more of an enclosure than a building. VC Aptowitz recalled Raynham's being like a big mobile home mad of metal. Commissioner Dentino also added it looked like a rectangular steel box. Director Babin then pointed out that the wall and the plantings will all shield and/or take away the view of the substation building. Mr. Rice then reiterated that the structure will not be openly visible. It will have a 12' wall around it and from Bird Rd. or one of the residences and will be below the elevation of Bird Road so in a sense you will be looking either up or straight at the structure. If the structure is altered or added to in any way it will make it both bigger and more expensive. The resident then asked if there was any structure that could fit the function and the fa<;ade that was presented to the abutters. Director Babin questioned the resident as to his previous remark about MMED having made a promise for specific things and not delivering. The resident then chose to rephrase that it was mentioned at the original hearing that he thought there would be an attempt to make the building fit in. Chairman Baldwin then stepped in and said that yes, all five of them agreed to work with the residents and now the resident feels as though the decisions have been made and the accommodations have ceased. Clerk Moran then pointed out efforts that are being made to minimize the visibility by means ofplantings, a 12-foot stained cast concrete wall that has a stone field look to it with a fence on the top of that. Director Babin then addressed the "house" look suggested for the substation exterior. The "house" that the residents saw on the internet site for Mississauga Canada was a shell that was set up on the land for an entirely underground substation. The substation itself had a completely underground structure where the entrance and exit for all equipment is underground. Director Babin pointed out that this is an entirely overhead substation and the fa<;ade look did not seem appropriate. He also stated that if National Grid had specific requirements for MMED to follow with respect to construction, MMED will have to adhere to that. The same resident then let Director Babin know that with all of the things that are being done to shield this structure why can't a more appealing siding or roof be found for this. He still feels that his residence will have a view of the actual metal structure behind the wall and plantings. Commissioner Dentino did say that yes, the wall will not go all the way around the structure. He assumes that there will be a fence with a gate at some point so there is access for the vehicles and equipment to enter and exit the premises. Commissioner Dentino questioned where that gate will be in relation to Bird Rd. Ms. Ruane let Commissioner. Dentino know that the gate would be alongside the National Grid easement. Director Babin added that it is perpendicular to the Transmission Tower side, facing the right-of-way. Commissioner Dentino said that it faces one abutter and that was a problem, and he also added that he did not like the stamped brick concrete wall. The brick looked like a penitentiary to Commissioner Dentino. - Commissioner Dentino thinks the aesthetics should be placed on the wall, not the structure inside. He inquired as to what is being planned for around the wall area. Ms. Ruane said that those plans are still being developed but right now the concept design has shrubs that will grow to about 12' at mature height so nothing can be climbed or fall over into the substation in a hazardous manner. Ms. Ruane also said that the further away you get from the wall (including towards the new development) the taller the trees get. At mature height it will create a sort of a canopy to help with the downward view too. Ms. Ruane then stated there will be 16-20' trees, on adjacent properties but not against the wall, those will only reach 12' max. Commissioner Dentino then questioned the gate being a heavy wrought iron gate. Mr. Rice then answered that the plan is for a motorized sliding gate; a black tube and chain link. It will have something to make it solid to block the view and remain not climbable. The gate could possibly be up to 12' high. Commissioner Levine then had a question for the resident from 12 Colonial Dr. Commissioner Levine wanted to verify if the resident had more of a problem with the trailer itself, or the color of it. He stated that the trailer is the problem. Commissioner Levine then added that if the color had been the issue for him that it could probably be changed to help blend with the surroundings. The resident then said color was not an issue for him; he didn't care if it was "brown, green, or red". The resident simply stated the trailer was his issue. Commissioner Levine then addressed the same resident and said that even thought the trailer was not his first choice, but if that was not an optional issue to change, that maybe the color could be changed to help abate some of the dislike of the trailer itself. Ms. Ruane pointed out that if the structure color changes to something other than gray (to match the surrounding equipment and the concrete pad it sits on) another color may cause an immediate contrast with the surrounding colors. VC Aptowitz adds that if anyone does go to Raynham that they mayor may not like the wall, but if they are just driving by you cannot see anything other than the gate. He says that if the gate or fence is black it will not be seen from Bird Rd. Chairman Baldwin than asked if seeing it from the road is even the issue or if seeing it from a second level is the issue. Mr. Rice stated that for an alternate look a larger building would be needed and it would also be increasing the volume of the equipment inside. Clerk Moran added that you might see something other than the gray box, but you would still see the gray concrete pad that the structure is on, you will still see the transformers, you are going to see a lot of industrial looking things if you have a view over that wall. The resident from 501 Bird Rd. again approached the podium and asked when decisions on wall material, the gate, etc. are going to be made. Chairman Baldwin responded that they would be made at the Site Plan Review. Commissioner Dentino added that this was done at a Planning Board meeting. Director Babin said that MMED is going to recommend that the fence design look more like what the abutters agreed on. The same resident then questioned the audible volume from the equipment. Mr. Rice says that there is an audible sound level next to the equipment but he also pointed out that it trails off quickly as you begin to go further from the structure. Commissioner Dentino added that at 100' ~ he could not hear the Raynham facility. Vice Chairman Aptowitz added that if you wait until there is no traffic then 30' should suffice to not hear the equipment. Commissioner Dentino added that it is on Richmond St. off ofRt. 44.The resident thanked the Board and asked where the April 29th meeting will be held, who would be notified of dates, times, and locations, and also if it will be for the whole neighborhood. Director Babin said that the whole neighborhood will be notified as it had been for this meeting. He also mentioned it was going to in the same room that this meeting was in. Chairman Baldwin mentioned that the 29th is a Wednesday, a regular Selectman's meeting day and that the Board could incorporate something with the Planning Board. The resident from 61 Bird Rd. wanted to verify that the meeting on the 29th is when the final decisions on the plantings will be made. Director Babin answered yes. The plans will be prepared and submitted before that date, but the goal would to get approval that night. Director Babin also reassured the abutters that they will see the final design proposal before it is submitted. According to Director Babin these are the pictorial renderings, which were not ready for this meeting. Chairman Baldwin asked if anyone knows if the majority of the trees on Mr. Zola's property are coming down. One man in the audience said that he thinks most of the trees are coming down. Chairman Baldwin was trying to get a better perspective of their view. Director Babin said that MMED is going to try and tie in the grading and then the retaining wall may not be necessary for Stanley Circle. Once the plantings on the resident's properties begin to take hold and grow there should be a significant alleviation on the view. The resident from 19 Mary D Lane had questions regarding the safety of the gate, and also which safety features will be in place since there are lots of kids in the neighborhood that will be tempted to go out and check out the new facility. Mr. Rice addressed this issue by letting him know that the gate will be quite substantial, and well sealed to prevent any squeezing through. There will be secure locks on the gate and the building with an alarm system. The alarm system will be implemented to work with the SCADA to record all authorized and un-authorized entries. Vice Chairman Aptowitz asked if it would have a card swipe system and Director Babin said it is being considered, but not implemented anywhere. The resident asked if the mention of a chain link fence was injest due to the climbing opportunities. Director Babin said that they might be limited with their options for this rolling gate, but options will be considered. Ms. Ruane mentioned the possibility of a steel picket fence. The resident then let Director Babin know that there were not enough copies of the presentation for everyone and asked if extras could be brought to the April 29th meeting or even put on the website. He also requested the proposed plans be put online before they are submitted so that the residents have a chance to go over the info and be able too understand. Director Babin said he want sure if it could be done but would try to accommodate the request. Chairman Baldwin asked if the site plan could be sent out with the letter of the meeting. Director Babin said he was not sure how large that packet would be. The resident then said that it why he was requesting something on the website. Vice Chairman Aptowitz mentioned the possibility of having them available at the Light Dept. on High St. Vice Chairman Aptowitz also asked if the entire ~ neighborhood could be included in the next notification. Director Babin pointed out that due to the number of residences involved that Room 3AIB would definitely be needed for the meeting on the 29th. The resident then proceeded to ask a question regarding how the possible National Grid substation in Foxboro would affect MMED's proposed structure. Director Babin then explained that we would be bringing a transmission line up from Easton and MMED is going to make provisions so that National Grid could take it out of the station and continue it down into Foxboro. If the line actually extends to West Walpole, NStar will then be involved. The more involvement with NStar the longer it will take. Director Babin projects that within 5 years the extension will be built. Mr. Rice explained that the equipment required to do the extension will be part of the original build so things will not have to be modified to construct it. The resident asked if this will then affect all the EMF testing results. Mr. Rice explained that the line originates in Bridgewater, goes to the National Grid Substation in Eason where they tap off of it, and then it comes to us. He presumes from an electrical standpoint that Mansfield will be the half way point once it is decided to extend the line to Foxboro and eventually to West Walpole. Since it is a National Grid transmission line MMED cannot control that and it will be running parallel to the existing lines. Commissioner Levine then asked Ms. Ruane about the plantings and the height ratio. Ms. Ruane explained that the further you get from the wall the taller the plantings will be. Some species even reach 50-60'. And, it might be something like evergreens and birch to give it some diversity yet keep the buffer year round. The resident from 161 Bird Rd had the next request. She wanted to know if it would be possible to get an agreement to do periodic EMF testing from the resident's houses. She suggested semi- annually or annually, just having an agreement in place. Director Babin said that something should be able to be worked out. Commissioner Dentino recommended once a year in the summer when the EMF will be at its peak. Clerk Moran wanted assurance that that these mitigation steps (i.e. wall plantings, everything) has been factored into the cost analysis. It is just as important as the engineering. Vice Chairman Aptowitz then asked Director Babin if the situation with National Grid and the cost of the easement has been rectified. Director Babin replied that National Grid had given MMED a figure of almost $250,000 for the cost of the easement. The methodology of figuring this cost was based on the appraisal industry standards. Director Babin said that MMED is waiting for the draft easement agreement from National Grid. National Grid had given the indication that MMED will be able to obtain the land from them and it is basically a price negotiation in developing the final legal easement agreement. Ms Ruane was asked about the stamp of the concrete wall by Commissioner Dentino. She said it is the Fieldstone stamp. It is a cast-in-place concrete base with piers so that it won't look manufactured. The Fieldstone stamp is at the Mansfield Mall if anyone wants to go and have a better idea of what is being proposed. Commissioner Levine questioned the type of maintenance 11 . , this wall will need. Ms. Ruane said that it is very minimal. Refreshing the color if needed or repair any damages if it's hit by a vehicle. Otherwise it is there to fade and blend in with the surroundings and be a backdrop to the plant surroundings. Director Babin also pointed out that the ground covering will need to be maintained. He said MMED would keep the ground cover cleaned up regularly. A resident brought up that deer can jump extremely high. Ms. Ruane agreed but pointed out that it is almost always for a food source. Since they can run completely around the wall but they will be very unlikely to try to jump over the wall to get into the substation area. Chairman Baldwin asked if there were any further questions. Director Babin wanted to get a sense ofthe Board with respect to the project after hearing the presentations. Commissioner Levine said that the schedule makes sense and appreciated all the thought and considerations that are going into this project. Clerk Moran would like actual samples of the fence material and get everything necessary in place to be ready for the Site Plan meeting on April 29th. Chairman Baldwin asked if Director Babin was looking for a vote. Director Babin simply stated he came to seek approval of the design concept but not an official vote. There was one more request from a resident to get a more detailed timeline of events. Director Babin indicated that he had a very detailed schedule from the last meeting that he could provide. Chairman Baldwin again asked if Director Babin was looking for a stamp of approval and Director Babin said he was looking more for a sense that the Board considers things on track and able to move ahead. Based on Board feedback, the sense of the Board is that MMED had covered the important issues and that the staff can move forward. Commissioner Levine made a recommendation that does not require a vote; it is simply stating it is OK for MMED to proceed.
