?•; board members had at the last meeting. The first being the height of the building, which has been reduced by 5' ft. and now falls within the height restrictions of the zoning code. We have toned down the building, taking it from a bright blue to a sedate green, and will keep the roofing which is shingle. We have tried to pull the building down in size and presence for this neighborhood The landscaping plans that were submitted today will show the neighboring properties that abut Wellington. Both the east side, and the south side will be shielded by the existing trees. Mr. Tallon asked if all three stories would be brick. Mr. McGettrick stated no, brick will only be on the first two floors. Mr. Tallon suggested in order to achieve a solid barrier between you and the surround.ing lots, bare areas will need to be filled with shrubbery. We would also like to see ever greens put in to provide screening in the winter months. Mr. Koeth asked how far the retention pond would be from Brookpark Road. Not from center line but from the edge of the road. Due to background noise on the tape Mr. McGettrick's answer could not be heard. Mr. Koeth asked is this a wet pond which will be used for the overflow of tlie retention system. Mr. Krall stated it will act as a retention system with the overflow discharged to undergrouud storage tanks. Mr. Tallon asked how big is the underground system. Mr. Krall suggested it is roughly 25% of the overall retention required, which will be roughly 8,000 cubic feet of storage. Mr. Tallon asked what is the slope on the above grou.ud retention pond. Mr. Krall stated roughly 1 and 3, it is roughly 15' ft. Mrs. O'Rourke asked how often the water in the pond would reach 6' feet in depth. Mr. Krall suggested the retention pond will start with a certain level of water in it so we can provide aeration. Within the top of the pond a 3 ft. cap will be placed that retains water, so the water will rise to 3' ft., and be stored for eventual discharge into the storm water system. In the event of a larger storm, such as a 50 year storm event the pond overflows into the underground storage tank system The underground tanks would then discharge into the City system at a very slow rate. Mrs. O'Rourke again questioned will the water in the pond be 6 ft. deep all the time. Mr. Krall stated from the bottom of the pond to the top will be roughly 6£eet. We envision the average depth to be roughly 3:5 ft. to 4 ft. deepr. Mr. Tallon asked were will the underground tanks tie into the City sewer line. Mr. Krall stated there is an existing sewer line under Brookpark Road that we will tie into, which is below the grade level of the pond. Mr. Tallon suggested then you will always have standing water in the pond. Mr. ' Krall stated first of all the water will drain down into the pond through a series of these head walls, then it is going to discharge up to a certain level. From there it discharges into a man hole and then into the City. In the event there is a large storm event such as 50 or 100 year storm that can't be carried by the discharge offthe headwall of the pond. It will overflow into the undergrou.nd tank system to the top of it. Mr. Tallon stated then in other words, it overIlows into the parking lot. Mr. Tallon asked Mr. Deichmann the City Engineer if his office had a chance to look at the plans yet. Mr. Deichmann stated as these pians were just received today, our office has not had a chance to review them Mr. Tallon stated the board doesn't see why the whole detention system isn't just put underground. We don't like the idea of it being so close to Brookpark Road, or it being right next to the parking lot, and that close to the building for that matter. Mr. Krall suggested what we have tried to do is copy what we have done at Butternut Square which was a combination of a pond and a detention basin. Mr. Tallon stated we are not here to discuss Butternut Square. Mr. Krall asked the chairman by the Code book are we allowed or permitted a wet retention in this zoning district. Mr. Tallon stated you are allowed with the agreement of the engineering department based on 2
