David Langseth asked if the chemicals proposed were the same type used at the Old Reservoir, Mr. Wwinzapfel replies that they are the same. Mr. Wolk commented that some of the residents whose houses are close to the pond are mowing up to the edge of the pond. Mr. Wolk asked if any of these residents use fertilizer and suggested increasing the natural vegetated buffer zone along the pond bank to improve the water quality in the pond. Mr. Weinzapfel responded that a poll was taken and found that none of the residents inside of the watershed had used fertilizer in the last few years. Mr. Weinzapfel also said that plan could be amendable to increase the natural buffer zone. Mr. Kennedy asked if Mr. Weinzapfel is confident that proposed chemicals will not harm amphibians. Mr. Weinzapfel responded by staying that chemicals were approved by the state pesticide Bureau and safe to use for aquatic management. Ms. Frick commented that the buffer zone along the pond bank needs to be improved. Mr. Bitsko pointed out that buffers are important for aesthetics as well as storm water runoff treatment and infiltration.
