MINUTES OF THE PLANNING COMMISSION MEETING SEPTEMBER F, 1989 ZONING FILE #1411-SUSSEX SQUARE CONTINUED Mr. Gronberg showed four options being considered for entrance gates. Mr. Gronberg provided a detailed explanation of the drainage pattern fcr the property. He said that the detention pond had such a capacity that 100 year storm water runGff would only raise the level of the pond 1/4". He said that a raffle weir would be installed to improve water quality, Gronberg said that Area 2 was presently a problem because the 12" culvert running west under Leaf Street was plugged and because of it being so small, would overflow in a 100 year storm. He was proposing to dig out a much larger holding pond and take the storm water into that pond. He said that an attempt would be made to do the road grades in such a way thst drainage would remain the same, however, there will be small increases in each watershed area that will be dealt with individually. ;ronberu said that there had been concern expressed about over -development of this parcel.

Mabusth said that the City would take drainage easements over all of the drainage ways and detention/retention areas. If the Homeowners Association failed to make necessary repairs to the drainage system, the City would have the right to make the necessary reparis in emergency situations and assess costs against individual homeowners. Chairman Kelley opined that he was in favor of the through road with no right angle or stop sign. Kelley said that it would take less time to qo from Leaf Street directly to Fax Street. Kelley said that it would also be easier to maintain the through road if it was configured with no right angle. Gronberg said that they would be willing to forego the right angle if the City indicated that preference. Planning Commissioner Johnson concurred with Kelley. He said that the road would only be used by residents of the subdiv.4Sion and they would probably tend to cut the corner if E
