After the initial review, the applicant took time to develop a solution to some of the concerns raised. In addition, this application has been continued without a hearing for a number of months. As a result, a new plan set was submitted on March 29, 2019 along with a revised storm water management report and distributed to the Board. The Peer Review consultant has not yet completed his review of the revised plans and report. Beverly Planning Board Meeting Minutes April 30, 2019 Darlene Wynne tells the Board that the project engineer and applicant are requesting a continuance of the Public Hearing to give them more time to respond to the Peer Review. In addition, the abutters are also requesting an extension to have time to review the Peer Review. Flannery: Motion to continue the Public Hearing to the June 18, 2019 meeting.

Continued Public Hearing: 53 Williams Street Definitive Subdivision Plan — MJP Properties — Creation of private way, demolition of existing single family residence, and development of two single family residences. Materials added into the record: • Planning Department Staff Report, dated 4/30/19 This Public Hearing was continued without opening the public hearing at the April 9, 2019 meeting. Wynne reads the Public Notice. The applicant has proposed a new private roadway of 40' wide by 57' long that acts as a hammerhead turn - around at the end of Williams Street and creates frontage for two residential single - family lots, where one lot exists now. An existing house on the lot will be demolished and two new houses built. She then tells the Board that they have received additional comment letters and has left a copy of each for everyone at their desk. Bob Griffin of Griffin Engineering reviews the existing conditions. He shows the Board an aerial photo noting it is a 1.08 -acre subdivision, with 163 feet of frontage in the R10 zoning district. Griffin shows the Board additional photos as well as the survey plan that indicates an L shaped parcel. He points out some wetlands on the property and a bordering vegetated wetland (BVW) that flows in a southerly direction. The wetlands drain down through the golf course, and then runs up to the wetlands and then connected to the stream to the corner of the site. He tells the Board the whereabouts on the plan where the Conservation Commission jurisdiction applies. Griffin mentions at the existing house located at 57 Williams Street, there are remnants of old concrete foundations. In addition, the property has some small trees, along with some scrub vegetation throughout. Griffin says they are proposing to remove the existing house, as well as the old foundations and build two, single family houses. They will also add a hammerhead turn- around to the new roadway. In the new plan, the turn- around is extended another 25 feet in order to meet the Building Inspector's calculation for frontage. Griffin then shows them the updated site plan. With the turn- around being 25 feet longer it pushes the house a little bit further back. The property has 1.08 acres total which allows approximately 20,000 sq. ft. for each lot. Griffin explains that with the grading on the site that the water flows onto the property and then flows down to the BVW. They are proposing to add two catch basins which will then flow into a manhole, to the back part of the property and discharge underground which will flow down to the BVW. This is the same drainage pattern that has existed in the past. They would like to also Beverly Planning Board Meeting Minutes April 30, 2019 add some infiltration onto the site and points out those areas on the plan. They will also add a berm into the infiltration trench, which will be about 24 inches high. He shows the areas in which it will be captured to slow it down, and it will flow into the ground or up over the berm and downhill to the wetlands. This will help reduce the amount of water rate and volume in that direction. Griffin mentions that the hammerhead turn- around was determined favorable by the Fire Department. The Fire Department did mention the houses may need sprinklers if they are more than 500 feet from a water main. Since they last filed the plans, they have made some detailed changes. They have added filters into the catch basins, which are stainless steel screens that will catch some solids. They have added responsibilities to the HOA to have the system inspected and make repairs as necessary. Griffin tells the Board that they have asked for some waivers for the plan including: 1. Planning Board accept the Plans drawn at a scale of 1 " =20' instead of I"=40'. 2. That an Index sheet showing the entire subdivision at 1' =100" not be provided. 3. Request the plans not show the location of the trees to be retained with trunks over 6- inches in diameter, measured 4 -feet above the ground. Trees located adjacent to the proposed private way are shown in the plans. The project area is primarily wooded, consisting of mature trees and scrub vegetation. The proposed work was located as close to Williams Street as possible to limit the amount of clearing required for the project. 4. That the minimum width of the right -of -way be 50 -feet and the minimum pavement width be 32 -feet. 5. That a dead end street not be longer than 500 -feet. 6. That instead of a cul -de -sac they will put in a hammerhead turn around. 7. No sidewalks since there are none currently on Williams Street. 8. No curbing since there is no curbing currently_ 9. No street trees are being proposed because there is ample vegetation already on the site. 10. No fire alarm being proposed because that is from the old subdivision regulations. Griffin notes that the Conservation Commission has reviewed the plan and there is some correspondence in the staff reports but no major issues that they see. Craft asks Griffin to give the details again of the width of the right of way. Griffin tells him that the width is about 48 feet, so it is almost at the 50 -foot requirement, and the length is 82 feet. In addition, the radius on the curbs is 30 feet. The total acreage taken up with the turn- around is 0.1 acres. On Lot 1 it is 0.4 acres, and on Lot 2, it is 0.2 acres, so the total area is 0.6 acres. Craft then asks Griffin what is a paved surface and what is an unpaved surface on the right of way. Griffin explains that it is 20 feet wide and each driveway is about 15 feet wide. Boesch comments that they have a letter from the Environmental Planner about a conflict with an exposed ledge. Griffin explains that it is an exposed ledge and the 100 -foot buffer zone runs through it. If they were to remove the ledge, they would be encroaching within the buffer zone. Griffin mentions that they won't remove the entire ledge and can possibly pin the footing of the house to the ledge. They could possibly go deep to construct a basement. They are hoping to Beverly Planning Board Meeting Minutes April 30, 2019 hammer the ledge to get the building footprint in. There is about 8 -10 feet of ledge exposed that would have to be removed to construct the basement. Ned Barrett asks about the rip rap and is it already existing or something Griffin plans to install. Griffin explains that there are two new catch basins and points out where the water flow area will follow. It is all proposed construction. Barrett then asks if rip rap is favorable as opposed to pipe or a water management system. Griffin says it is less expensive than installing a stone channel and a rip rap discharge. They are looking to restore the current drainage system. He notes that a neighbor does have concerns as some of the water flows by his retaining wall, however they are not proposing any new construction by his property. Griffin believes they are improving that area on their new plan. Griffin also explains that the rip rap is intended to stop erosion from happening which will help slow the water flow down. Barrett asks Griffin what happens if the rip rap floods. Griffin tells him that the water will go downhill to the channel, and then to the BVW. Barrett comments that he is concerned for Mr. Mendola's property and the concerns he has expressed for his property. Barrett then asks about possible erosion of Mr. Mendola's retaining wall. Griffin shows on the plans where the water will be flowing in association with Mendola's property and says that it won't affect his property. Barrett asks what he would recommend for Mendola to do to further protect his property. Griffin tells him that the changes they have made in the past couple of months including extending the pipes around the corner takes water that was previously running along his wall and puts it into a different spot and flows with water away from his property. Barrett asks about some other options and Griffin explains why those wouldn't work. He explains that an infiltration strip to the ground would work better. Barrett then comments to Griffin about some of the waivers that they are requesting. He asks about the scale waiver noting that Griffin commented it is not a large lot, but then Griffin had also asked to waive the mapping of the trees. Barrett suggests that maybe a compromise would be to locate and map the trees 12 inches in diameter. Hutchinson asks Griffin to describe infiltration strips. Griffin explains that they are usually 2 feet wide and 2 feet deep with crushed stone and a pipe in the bottom of it. It moves water along laterally in the back along the trench so if there is a spot in the ground that receives more water than another, it will be able to get a lot of water to it. Hutchinson is concerned that this is a two person /two home HOA, and asks if there is an itemized list of everything they would be responsible for and what the cost of that would be. Griffin tells her that they would be responsible for: inspections of the drainage system (first year, quarterly, and annually thereafter), a report to the Engineering Department at the end of each year, with any deficiencies reported to the department within 48 hours of discovery, site clean-up in the roadway, weekly litter clean-up, significant oil leaks or spills should be cleaned up, wetland area be photographed and inspected annually to show that it has not been disturbed or changing, and snow removal. Griffin estimates that the cost will be around $5,000 a year for the HOA. Hutchinson then asks about the cost of maintenance of the stormwater berm. Griffin comments that the home owners want to be sure a lot of vegetation is not growing on the berm. Derek Beckwith asks how far the retaining wall is at 51 Williams Street from the property line. Griffin tells him that it is on the property line. Beckwith then asks how far from the property line 4 Beverly Planning Board Meeting Minutes April 30, 2019 will they be doing any construction work. Griffin points out where they will be doing grading work which is about 5 feet from the wall. Wynne asks Griffin where he is calculating the frontage and he shows her on the plan. Wynne then asks why he changed the frontage from a triangular shape and squared it off. Griffin explains that they are trying to keep the houses as close to the street as possible. Hutchinson opens the floor to members of the public to speak and ask questions. Joe Mendola, owner of 51 Williams Street, tells the Board that his concerns are his retaining wall and water coming down near his property. Mendola points out the contours on the map and where the water currently flows, which he says seems to head straight towards the retaining wall. He also feels like there will be a lot of debris coming down as well. He is concerned that the HOA wouldn't be able to handle all of the maintenance required. He received the storm water report the day before so he has only had a little bit of time to review it. In addition, he is worried that part of the property will be flooded. His concerns have increased after seeing the second revisions of the plan. Barrett asks Mendola what water he currently gets on his property. Mendola tells him that he doesn't get much. It is his rental property that he doesn't visit often because there are usually no issues with it. But he believes with the changes to the abutting property that the water will be coming down hard towards the wall and concentrating in that area. Hutchinson asks Griffin to respond to Mendola's concerns. Griffin shows the existing drainage pattern and the water flows. Griffin then explains that there will be less water heading in that direction after construction because a lot of the water will be pushed to the east. Griffin disagrees that the water will be coming down hard at the wall because the driveway is running away from his property. They will be placing fill 5 feet from the property line to create a grade for the driveway which pushes all the water to the east. Water will be picked up in the catch basins and piped around the back corner, so there will be a lot less water against Mendola's wall than currently. He notes a drainage easement. He says that if the HOA does not take care of it, someone from the City will have the right to access the area to inspect it or maintain it. Griffin also shows the condition of the back yard, and notes there is some ponding. Hutchinson asks Mendola if he has any further questions for Griffin. Mendola asks for more of an explanation of what he sees as a water flow on the contours as opposed to what Griffin is interpreting. Mendola suggests a different area for the water to flow. Griffin explains why that wouldn't work. Griffin comments that they are trying to keep the current drainage flow to the BVW so it doesn't affect Mendola's property. Hutchinson asks if the stormwater report has calculations of the differences in the varying flows. Griffin points it out in the report, noting that the post - development run off rate is one -third of the pre - development rate. Anna Langstaff, 47 Williams Street, asks if there will be any blasting on the ledge, and wants to know what trees will be affected in the neighborhood. Barrett explains that they are required to Beverly Planning Board Meeting Minutes April 30, 2019 map trees that are bigger than 6 inches in diameter, but they are seeking a waiver for that. Instead they are suggesting they map trees at least 12 inches in diameter to compromise. Langstaff also asks where the construction vehicles will be parked during construction. She then asks if the property owner could remove all the current trash on the property. Griffin comments that the former owner let the property go quite a bit so they will clean it up. With regard to the blasting, Griffin explains that they are trying to lift the houses up a little bit so they don't have to dig deep into the ground. They will try to hammer out the ledge first before they decide to do any blasting. The construction crews shouldn't take up too much of the street. Langstaff asks what the timeline is for the construction. Griffin tells her it will probably be about 6 -9 months of construction work on the property. Karen Adamo, 49 Williams Street, wants to know how this project will affect her property. She is concerned about getting additional water since her yard already tends to get water. Griffin assures her that more water will not be a problem for her property. Adamo then asks when the existing house gets demolished what they will do if there are any creatures living in it. Griffin explains that the Board of Health requires that they will need to set traps and also make sure if there is any asbestos in the house that they will remove it ahead of time before they demolish it. Hutchinson states that Barrett would like to add to any motions that they map trees 12 inches or greater in diameter. They would like to see that before the vote on the plan to make sure there are trees that may need to be retained. Wynne states it is a good idea to continue the hearing due to the fact they just received the plans as well as the Engineering letter and will need more time to review.
