02-07-1996 Meeting• In attendance: NATURAL RESOURCES SUBCOMMITTEE MEETING (FEBRUARY 7, 1996) - Meeting Summary- Lee Markell, APRNRC Steve Thompson, APRNRC John Barten, Hennepin Co. Parks Paul Olson, Staff Rich Brasch, Staff Meeting Summary: I. Water Quality Management Program Review John Barten, water quality manager with Hennepin County Parks, was invited to the meeting to provide his perspectives on the water quality management program. John was heavily involved in the development of the technical aspects of the plan and program, and works extensively with other communities in his capacity as water quality manager for Hennepin Parks. Following is a summary of John's remarks: His main expectation for the program over the first 5 years was simply to prevent further degradation in the community's priority water bodies. He had no expectations of dramatic improvements in water quality during the first 5 -10 years of the program. John emphasized the long -term nature of lake restoration, citing his experience with the City of Wauseca and the 9 -10 year effort required to successfully rehabilitate two lakes in the town. In John's opinion, managing urban lakes is like managing urban parks. Both are highly altered systems that take intensive management in order to achieve the level of quality necessary to satisfy the demands they are expected to fulfill. In his experience, the public will not accept poor water quality for very long so the commitment needs to made for water as it does for parks. In addition, it is important to take a very long view of the actual and potential value of the resource. Steps taken to protect lakes today may will have benefits to the public 50 -100 yrs in the future. He believes these resources will only come to be • valued more highly by the public as time progresses. • II. Wetland Buffer Ordinance From what he knows about the program, its major success has been the implementation of the public education component of the program. The major weakness may be the lack of an ordinance restricting the amount of phosphorus in fertilizer. John believes that while education is important and desirable, it is unrealistic to expect that it will substantially change behavior over even the intermediate term, and that education efforts need to be combined with regulatory tools to have an impact. There was some discussion regarding the strategies that could be employed to develop facilities to support direct contact recreation on City lakes and ponds. John mentioned his experience with beach curtains, pumping /re- circulation of shallow groundwater, and alum treatments in maintaining swimming areas for Hennepin Parks. He mentioned costs for a beach curtain sufficient to enclose 1 acre at about $12,000 and that it required about 16 -20 man -hours to install the curtains. The subcommittee members mentioned that it might be desirable to look at the feasibility of developing direct contact recreation facilities on a number of community lakes and ponds, including Heine Pond, Carlson Lake, Schwanz Lake, Fish Lake, and Blackhawk Lake. A codified version of the draft wetland ordinance discussed at the last meeting was distributed as was a model wetland buffer ordinance based on one adopted within the last year by the City of Maplewood. (Note: L. Markell needed to leave meeting at this point due to scheduling conflict) Staff reviewed application of the Subcommittee's draft ordinance to four developments and discussed the administrative issues that arose and the need for possible exemption and variance provisions to provide flexibility in the application of the ordinance. Staff were directed to incorporate several exemption, variance, and easement provisions from the model ordinance into the Subcommittee draft. Another meeting of the subcommittee was scheduled for 5:00 p.m. Tuesday, February 20 to review the revised draft. (Meeting summary prepared 2/8/96 by R. Brasch)
