A. There will be one near Cross Lane Nancy: Possible flooding in Thissell Brook, what about those who live on Hale Street? A. Water detention basins were designed Post construction would be as normal free running stream this is a high iron content from ground. Nancy: Many hundreds of frogs are there, are you aware? Will they live there? A. Yes most will inhabit near the storm drain. Nancy: Will lots of flooding still continue? A. By removal of two blockage pipes, upstream water has been released in '89 removal has alliviated it. Bill: A confusing site-needs marking-this is a start flagging where are you intending to do it? A; There are encoded flags Bill: Still confusing site--need another site visit. Vincent: What feeds vegetation? Kurt: Ground water Kurt: Yes, but ground water follows the stream. It's a discharge not recharge condition, Vinnie: Replication of bank- how do you replicate a bank with a bank? A. Not replacing the bank but the habitat? Nancy? Are you going to build houses? A: Yes, but will design and ones in buffer zone will come to the commission your approval. Bill Lisa: Houses will be impermiable ground. Policy in the past has been to note dwellings and driveways. Vasek: The problem is they will not be built as we have drawn now. Bill: 13 house lots-chance any are not buildable? Vasek: They have been taken into account Kurt: Lot 11 needs approval-long driveway and will have impact on wetlands. Peter: Size of upland on lot 117 Kurt E-W 160 N-S 180 at largest point. Bill: So houses are in thought? Nancy? How can we approve without a definite of houses? Peter: We can agree to this later, they will have to come back to the commission. George Zambouras: Will be tied into sewerage Vinnie: Road pollution: Have you done anything? Kurt: Yes Vinnie: Could outflow be moved to a different area so inflow and outflow are further apart? Vasek: Would have to look into it. Vinnie: Would be better protection- 8 inch difference? George Zambouras: Concerns: Review of Hydraulic analysis minor problems 1) impervious areas should be larger-would have direct affect of 100 year flood post conditions have not taken into effect. Property does overflow during a storm. Minor notation added to Order of Conditions (Since this has already been approved by the planning board.) Vinnie: related to playground--very near the pond Kids playing near wetland now becomes wetland issue-There is a fenced area. Vinnie: This is both a wetland and safety issue. Planning department says doesn't have to be there. Alan: tot-lot was matter of significant discussion Vinnie: Banks aren't stable--replace tot-lot Alan: Tot lot was impossed. Vasek: a 5 foot fence Clayton: Who would assume responsibility? Alan: The developer Peter: When lots are sold, then who? Alan: For now the developer Peter: A variance could eliminate Birchwood Drive. Alan: No Alan: During construction we would put haybale lines up stream so no blockage occurs. GENERAL PUBLIC David Heslop 111 Cross Lane Disturbing intergrated habitat then becomes fragmented Kurt: lots of small mammels are there Heslop: Look into habitat distrubances, will still have loss of habitat Kurt: Will be able to get to and from stream when finished Mr. Davyan 103 Cross Lane abutter There are owls, chipmunks that need the stream--water quality filters through the ground what about nitrogen? Vasek: Nitrogen helps vegetation.; Davyan- The point is the detention pond won't help water quality. Majorie Hutt 71 Cross Lane Water in detention basin will be polluted Kurt: not great volume of road oil. Detention ponds could be cleaner than many receding waters. Marjorie: How many gallons of water will go in basin per minute Vasek: 100 year storm: outflow .9 per cubic feet per second= 7 gallons per second Detention pond will act as a buffer Marjorie: Water is not being released it's seeping in ground Kurt: Can't reduce water -reason for detention to buffer. Leroy Hutt 71 Cross Lane Few things disagree - This brook has not dried up. Depth of water on his property has gone 8 feet high. Water flows to Dane St. Beach Greater problem: high detention area 6 ft high- his brook has more water, the pond is higher than detention area. Wants commission to correct flow of water. Scott Carter 75 Cross Lane. Most Cross Lane is on Septic Tanks Concern: Saving trees Vasek: Won't be filling or causing ground water to rise. This development won't affect Cross Lanes Leeching fields. Debbie Heslop 111 Cross Lane- Severe flooding how will project affect ? She has been following project, and water sits in her yard. She has been studying its waterflows. Not convinced that situation won't worsen. Vasek: Your land is upstream Debbie: Obstacles are being created George: Solution is a drainage pipe Mr. Heslop: How do you control? Who will be responsible George: City would have to deed the property. Vinnie: Where road crosses, will there be a culvert? Vasek: Yes 3x6 culvert Vinnie: How will culvert work as well as open area?
