SHOREWOOD OAKS - continued Geoff Martin told the Commission that Shorewood Oaks' original plan was to use the natural drainage area. Gary Carl asked if, with the new project drainage, the natural drainage area wouldn't expand past what was shown on Shorewood Oaks' map. Tim Phenow, Shorewood Oaks' Engineer, said that the area shown on their map was that of a 11 100 year storm" and that the drainage from the new project was already included on the map. Commission would like to know how much additional water will be coming from the new project. They asked Shorewood Oaks if they would draw up a map showing them the difference. PARK COMMISSION MEETING FREEMAN PARK TOUR MONDAY, SEPTEMBER 17, 1984 page two Commission showed concern over the following: Wagner Pond —east of the BMX Track Engineer's Phenow and Norton said that the Wagner pond is 976', the "100 year storm" height is 969', a difference of 7 The water would go up and over the railroad track area before it would ever back up and create problems in the Wagner Pond area. Will more "hard Surface" in new development cause problems? No, the total rainfall doesn't change, therefore the water runoff into the drainage area will be the same. Open PondinQ Area — Is it feasible? Engineer Jim Norton suggested that Commission keep in mind the fact that Shorewood Oaks will be using perforated pipe, this will keep a flow moving. Commission discussed different ways of maintaining a water level. A sluice gate was one of the solutions mentioned. Engineer Phenow felt this could create a maintenance problem. One of the Commission's concerns about open ponding was the idea of stagnant water becoming a breeding ground for algae and mosquitoes. The question be— ing how to prevent this problem, and keep a clean water level. Engineer Norton mentioned that the main concern at the Council meeting was shown by citizens on the north end of the proposed holding pond, they were is afraid of the overflow coming through too fast and causing flooding problems on their property. Some of these properties already have existing problems. The drainage exiting the holding pond, equivalent to an 18" pipe, is already planned. Engineer Norton said that it is extremely important that the rate of discharge from the holding pond is limited. The holding pond overflow area consists of 11 acre feet of storage. Engineer Norton asked what the Commission would think of having two holding ponds, one near the development, and one in the planned project area. Engineer Tim Phenow mentioned 2 things he had in mind: 1. Dig out and widen the gullies. This would not be too expensive. 2. Build a deep, more compact holding pond. This could be more expensive. Commissioners asked Council Liaison Shaw if there had been any other major issues regarding the Shorewood Oaks project brought up at the Council level. He said they had discussed the density of the project. Commission has no problem with the area to be used but will continue discussion at an appropriate time on the possibility of making the ponding area smaller or having open water. Mari Kooi moved, Gary Carl seconded, to inform the Council that the Park Com— mission approves the project, and that the Park Commission requests to be • included in the Engineer's discussion.of the final plat regarding drainage and the ponding area. Motion carried unanimously. PARK COMMISSION MEETING MONDAY, SEPTEMBER 17, 1984 page three SHADY HILLS PARK Administrator Dan Vogt had sent a memo to the Park Commission asking them what their plans are for Shady Hills Park. Commissioner Con Schmid said that the pond is full of duckweed, and that two or three of the neighbors are interested in dredging out an area for ducks and geese. He will pursue this discussion further. Liaison Tad Shaw asked: 1. Is the park dedicated? 2. How was it acquired? 3. What is the value? 4. What can we do about it? Roger Stein moved, Mari Kooi seconded, to have Planner Nielsen research the property and see if it can be sold. Motion carried unanimously. TRIVESCO - PARKLAND Planner Nielsen informed the Commission that the developer (Trivesco) is currently negotiating with Mr. Bruce with the idea of trading 2 to 4 buildable lots for the parkland. Trivesco would then turn around and present the land to the City in lieu of a park fee. Planner Nielsen presented two drawings of the considered parkland with tennis courts, a hockey rink, a free skating rink, a regulation softball field, a play area, parking facilities and a shelter, showing different ways that they would fit unto the property. Planner Nielsen also gave an oral presentation to the Commission, in which he provided long range estimates of the monies available from park fees from Trivesco, Covington Vine Ridge, and Near Mountain. He will be sending a written report to the Commission regarding this issue. He did mention that a meeting had been held with Near Mountain and that they plan to proceed with their project. They do hope to make some changes. The Park Commission thanked Planner Nielsen and told him they thought he had done an excellent job, and that they were pleased with his presentation. Con Schmid moved, Roger Stein seconded, to recommend to Council to accept the Preliminary Park and Land Proposals for Trivesco as presented by Planner Nielsen. They wish to inform the Council that they are pleased with the project. Motion carried unanimously. MEETING NIGHT - MONDAY OR WEDNESDAY The Commission discussed changing the meeting night to Wednesday. Three people found that this would not fit into their schedule, so the meeting night will remain on Monday.
