line, tlien shifting to a split rail fence that will meander through the wooded area and this will be pulled into their side of the property which would give the appearance of the woods being on the adjacent property. Additionally, they are proposing an inner cordon fence around the primary water features which attaches to the building envelope to create a barrier to the water features. They believe that open water retention is the most superior way of controlling water retention. Mr. Mitchell, landscape architect, explained that, as a secondary safety precaution around the ponds, they have included in some areas, very gradual slopes ending in a large 8 to 12 foot wide safety shelf, only 18 inches cieep, so that if someone did fall in they could stand up; in the steeper areas they will include landscaping with plant material like shrub roses and hawthorns, which are hard to get through so that the only access would be to the very gradual slopes. These ponds are all visible from the rear of the houses. Mr. Basalla clarified that they will be planting evergreen trees on outside edge of the fence to screen it from view of the neighbors. He stated that, at the meeting of the residents, it was specified that they did not want more flooding, neither storm nor sanitary. He had previously stated that the pond system would reduce the flow by 33%, but it will be more than that and these statistics have been forwarded to th'e Engineering Department. He believed that they would be reducing the existing problems. W. Dargas, engineer, explained what has been proposed to reduce these problems. In reference to the sanitary sewer, they are proposing a two stage detention system, the first stage being at the site discharge point where they will control the discharge coming out of the site to detain the additional flow somewhat. Customarily they design for peak flow of 400 gallons per day (gpm) for each.unit, after the system is in place, it will hold back the discharge for two hours; also to help the system out, they have proposed a second stage of detention by installing 200 linear feet of 30 inch pipe toward the end of Sharon Drive where it discharges into Clague Road which will store more sanitary flow until the peak flow has passed through Clague Road before discharging back into the system In reference to the siltation issue, Mr. Basalla advised that there is a letter from the engineering company indicating that of the various means of water retention, the one the least impacted by siltation would be an open design since the discharge point for retention is at the top of the water, not the bottom. Regarding hazardous waste, the EPA has given them a clean bill of health after a study was presented by an environinental consulting firm. In reference to the wetlands, they have analyzed the soil conversation maps and the wetland delineation drawings and there is no indication of wetlands on this property. They also strongly believe that the storm water management system that they are proposing could not be replicated in a single family development, since the land would have to be divided into individual lots and there is little room to do any significant r.etention. In a cluster community, the residents do not use their back yards, they mainly want a view that is beautiful, not a swing set. He further maintained that this is a single family commu.nity wherein the residents, most likely residents from North Olmsted, will own their units and pay taxes on them. This community will be compatible with the adjacent single family developments. He believed that both the community and the small public works project that they are proposing will be valuable to the city. He stated that the master plan had specified that the site be rezoned to the Mixed Use "D" district which would allow for a variety of uses, including elderly housing at 40 units per acre, garden apartments at 15 units per acre, and single family cluster at 6 units per acre and they are proposing a lower density than that. Mr. Whitlatch advised that they are willing to commit to these proposals in writing and offer a two year warrantee on each unit. They want to work with the adjacent residents. He noted that today's new zoning for planned development or cluster development is considered single family housing. . They do not consider this a different typ e of use, 3
