DEC-01-2000 FRI 01:10 PH CB BURNET HAYZATA FAX NO.P.03 becomes plugged with debris, the water will overflow the banks of the pond, which is ten feet deep, and the potential for erosion and break down of the biirm becomes a real possibility. In a major rain event, if the burm beaks down, several homes will suffer major damage. (This scenario was brought up by one of the technical people who sit on the Water Shed District Board, but they advise that design and implementation issues are the City’s responsibility and not their jurisdiction.) The developers’ response was only to offer to have the burrns evaluated by a structural soil engineer and that the homeowner ’s a.ssociation would maintain the ponds. It is not appropriate to e.xpect the existing, down-stieam residents to provide the ponding for the additional run-off that these 5 home will ultimately generate. The rate of runoff may ultimately be lower, but I believe that the total volume of runoff will be far greater. The rate will be controlled by the 4-inch weir and the 12-inch pipe, but the total volume will increase and ultimately be ponded in the level lawns and driveways of the existing down- steam residents. The families on North Shore Drive and especially Forest Lake Landing are already experiencing problems. The added volume will make things worse after it slows on the level areas and drains into our driveways, lawns and homes. Another concern is that although the plan looks good, the implementation will be critical. How can I be assured that not one drop of additional run-off will reach my property? Who will supervise the implementation and when the five homes have been constructed, check that the drainage system is functioning properly and assure that it continues to be maintained so that it operates as designed? I’o that end 1 am requesting that the City of Orono take over maintenance of the weir and drain pipes and that the developer post a $200,000 bond with the city to be released after all homes are constructed and the implementation of the drainage system is deemed to be working as designed. In addition, I am requesting that the City of Orono evaluate possible solutions to alleviate the problems being experienced by the residents on Forest Lake Landing and possibly assess the Brenshcll development to procure funds to alleviate what will be a worsening problem. Finally, I would ask if the city has considered banning the use of fertili'zers and pesticides by these home owners, since the runoff will be mainlined from the holding ponds, down pipes to ravines and directly into to Forest
