Adjourn GAEnvironmental Commission\Agendas\042202.doc GOLDEN VALLEY ENVIRONMENTAL COMMISSION Regular Meeting Minutes March 25, 2002 Present: Richard Baker, Alicia Brown, Sue Hess, Dawn Hill, Alan Kuentz, Jessica Roe City Staff: Linda R. Loomis, Mayor; Al Lundstrom, Environmental Coordinator; Jeff Oliver, City Engineer; Tracy Pharr, Administrative Assistant Absent: None I. Call to Order Meeting called to order at 7:02 p.m. II. Approval of Minutes — January 28, 2002 No changes. MOTION: Moved by Hess, seconded by Kuentz, approve the minutes of the January 28, 2002 meeting as submitted. Roe and Brown abstained due to absence. Ill. Visit by New Mayor, Linda R. Loomis Hill invited Mayor Loomis to speak, and stated that Commission Members would follow with questions. Loomis said that no interviewing had yet been done for the vacant Commission Member space. She hopes this seat will be filled in May. The Mayor stated that after a new City Manager is hired, the Council would sit down with each individual commission and review bylaws and their current work plans, and talk about the Commissions' roles. She continued that one item she felt the Environmental Commission could be involved in would be the Second Generation of the Bassett Creek Watershed Management. She stated the Council is open to suggestions as well. There is an opening for an alternate on the Bassett Creek Watershed Management Commission. Mayor Loomis commented that this opening would probably be filled by a Council Member. Loomis continued that there are all different types of surface water management approaches. She stated that currently the City favors curb and gutter, but she would like to look at other approaches, including infiltration gardens, etc. Mayor Loomis said that the City has representation on the Watershed Commission, and part of the City is in the Minnehaha Creek Watershed District, and that the Commissions are supposed to GAEnvironmental Commission\Minutes\ECMinutes032502.doc take direction from the cities. Kuentz commented that he and David Fellman had participated in this process. Hill asked if this was still in progress. Kuentz responded that this process had ended. He continued that he felt the citizen role had been very limited and as a whole, unsuccessful. Baker asked Kuentz if he felt that his role had not been what he had hoped it would be. Kuentz stated that was "putting it mildly." Lundstrom added that he participated with Kuentz in an education group, and that there was also a technical group. The technical group was able to be involved more in "the meat" of the process. Kuentz asked Loomis if she had given any thought to what the Environmental Commission's role could be. Loomis answered that nothing specific had been determined. She does feel that the Commission needs more of a holistic movement, rather than a piecemeal approach. She would like to see the Commission more involved in planning processes. Kuentz commented that the Commission has not been involved in the planning process to this point. Hill asked Loomis about the reappointment memo that was sent to Commission Members. Loomis stated that initially the Council had planned to re -interview Commission Members, but that this would not be done as the Council has determined to be too busy. All current Commission Members will be reappointed. Hill asked the Mayor if she was planning on having a Council liaison to the Commission. Loomis answered that there are two liaisons for each Commission. Baker asked if the liaisons are supposed to periodically attend meetings. Mayor Loomis responded that they are supposed to attend at least once each year. Loomis concluded in discussing the hiring process and status of the search for a new City Manager. IV. Election of Officers for 2002 Hill called for the nominations of officers for 2002, beginning with the April meeting. Kuentz nominated Baker, provided he had the interest, to serve as Commission Chair. Baker agreed that he had the interest. He was unanimously elected to this role. Kuentz offered to serve as Vice Chair for the Commission. He, too, was unanimously elected. V. Bassett Creek Inventory Project Lundstrom commented that, to date, he had not yet received news on the Natural Resources Inventory grant award. He anticipates that results should be received in the next two weeks or so. Lundstrom distributed a handout of the Bassett Creek Inventory Project. He stated that this was a tool developed because of, and driven by, the Bassett Creek Watershed, to address community erosion issues. Staff decided to use in-house sources to inventory Bassett Creek. Baker asked why it was decided to keep this in-house. Lundstrom answered that this was a recommendation by Barr Engineering. They felt that, with training, staff could do this project well, particularly with their existing knowledge of Bassett Creek. Lundstrom agreed, as Public Works provides the maintenance for Bassett Creek in Golden Valley. Lundstrom continued that the inventory included all "reaches," typically areas between two roadways. He asked Commission Members to provide comment within the next month on the inventory. Lundstrom stated that every utility structure (storm sewer outlets) and its resulting problems, obstructions (leaning trees, private and public bridges, changes in creek), eroded areas and deposition were inventoried and photographed. He commented that all the information from the inventory would also be included and accessible from a database program. Oliver stated that the inventory would serve several purposes for the City, one being to help the City and the Environmental Commission to prioritize capital expenditures. Another purpose would be to assist in NPDES Phase II (Phase I covered Duluth, Minneapolis and St. Paul) permitting requirements. One requirement is that every storm sewer outfall in the community be inventoried. Baker asked if the Creek could potentially sustain some aquatic life in the future. He added that in removing some obstructions from the Creek, structure for fisheries habitat is also removed. Lundstrom said these were the type of comments and suggestions he would like to hear. VI. Other Business Items of Other Business: • Hill asked Brown and Hess if they would continue their appointments to the Environmental Commission. Both responded that they would be willing to serve. Brown and Roe filled out forms to update their contact information (as available to the public, and regarding duties as Commission Members). Other members completed these forms at the March Environmental Commission meeting. Kuentz commented that he would like to revisit the conversation about "wish list" items for future Environmental Commission meetings. No additional business was addressed. VI1. Adjourn The next scheduled meeting will be on May 20, 2002 at 7:00 p.m. The meeting was adjourned at 8:30 p.m. Respectfully submitted, racy Pharr Administrative Assistant Department of Public Works 3 Trac Pharr - Environmental Commission Agenda Pae 1 From: Al Lundstrom To: Jeff Oliver; Tracy Pharr Date: 4/12/02 3:06PM Subject: Environmental Commission Agenda Talked to Rick J. 2 He wanted us to let the Environmental Commission know they have set a tentitive date for the annual "Open Space Commission" park tour. On June Vfh Tom Klatt will lead a bus tour of the City parks. They usually meet at Brookview at 5:15 for a small dinner and get on the bus at 6:00. Tom could not make the forth Monday so they moved it ahead a week. Rick mentioned the Planning Commission was also interested in joining the tour. Please inform the Commission at the next meeting as I will be at the Open Space meeting.

This project will extend the natural resources inventory work already done in the Theodore Wirth Park area by the Minneapolis Park and Recreation Board through a previous Metro Greenways Planning grant. Additionally, it will increase the acreage mapped to MLCCS levels 4/5, both in the county and in the region. The reviewers were pleased to see the collaboration with Hennepin Conservation District, since this organization has undertaken most of the land cover mapping to date in the county. By working with HCD and MPRB, the city will be able to build on the past experiences of both of these organizations. Reviewers also expressed support of the city's intent to actively involve the Environmental Commission during the project period. A grant agreement will be sent out shortly for your signature. If you have any questions, please feel free to call me at the number above.

The enclosed options are a direct result of MnDOT responding to the concerns of Dave Hanson of the Sweeney Lake Association for current and past highway reconstruction projects. Both options are designed to divert storm water flows, entering Schaper Pond from the northwest, over longer distances to improve the settling of sediments before entering Sweeney Lake. During the construction of Schaper Park a narrow peninsula was installed to help divert flows to the south before short-circuiting to the pond outlet at the north end. However, there is speculation the peninsula is sinking due to poor soils. Staff would like both commissions to review the proposed options and provide comment. A staff member will be available at the April 22 commission meeting to review the options, maintenance costs and answer questions. In addition to the two enclosed options, MnDOT was required to install a skimming device within the Sweeney Lake stem of the of the Bassett Creek watershed as a direct result of commitments made during the development of Highway 1-394. Staff will provide a schematic of the skimmer and its location at the April meeting.

Biological uptake of dissolved pollutants is an important mechanism for controlling nutrients and could be part of the gravity settling system within the pond. This paper presents a mechanical and a biological method for increasing retention of nutrients and solids delivered from the NW pipe by restoring the function of the sunken berm. The purpose of the following analysis is to indicate the positive and negative benefits using two different approaches (mechanical verses bioengineered) to increase storm water retention time in the area of the sunken berm, and one with an additional potential benefit of biological uptake and filtration function.

JO • Se1)te)w)c, O t()bc,. 15 9.5 Luid fUid Wat( 1' SYCAMORE Lake isn't very- big, but it's right in the middle of Batesville, Indiana, a town of a few more than 4,000 people. Until two years ago, there were serious erosion problems along the banks of the lake. Now, the raw eroding banks are a thing of the past. The change is almost unbelievable. Chad Cremirtins, a landscaper, handled the installation of the measures that corrected the problem. Nutec Supply, Indianapolis, IN-, distributor of construction products, especial- ly those related to erosion control, furnished the materials for the Sycamore Lake project. "This was the hardest and most challenging job Tve ever done," admits Chad. He is quick to add, "It's probably the most satisfying job I've ever done." Several factors combined to cause the severe bank erosion. Four aerators. installed in the lake to increase the oxygen supply, created constant wave-like actions. "The waves just kept chewing away at the raw banks," says Bob Mattucci, who lives along the lakeside. Once this damaging effect was recognized, the aerators were removed. Storm sewers emptied huge amounts of stormwater into the upper end of the lake during heavy rainstorms. This further aggravated the bank erosion. Pat and Red Hare and their neighbors, Dave and Lynn Hirt, suffered serious erosion as the waves carried away 8 feet of bank along their property. They decided "enough is enough," and sought help. They Did Something About It The solution to their problem came from Jim Blazek, Sales Manager, Nutec. Based upon experiences with similar prob- lems, he suggested creating a `living seawall' using a combination of rock rolls, fiber rolls, unvegetated fiber mats and plant plugs. "Much of bioengineering technology comes from Germany," Jim explains. "We've learned a lot from the German experience as well as our own experience here in the USA." The company has been using erosion control mats since 1987 and fiber coir rolls since 1991. Coir is coconut fiber known for its high tensile strength, moisture retention and longevity. Once installed, it degrades in 7-10 years. Montelle Pike, a University of Indiana - educated biologist, runs what could be called a " dryland' (or manmade) t�,edand at Nutec headquarters. It is about an acre in size. Montelle produces about 50 species of wetland plants that he uses in making plant plugs, vegetated mats; vegetated fiber rolls and coconut baskets. "We get better results when we plug a number of different species at any given location," he explains. `We can select those that grow naturally in the area where we are working. Also; we try to include any particular species that the prop- erty owner might prefer. Growing plant plugs is a relatively new business for us, but the demand increases every year.'' A Tricky Location At Svcamore Lake The agreed -on bioengineerng solution was first tried on a 20' -long section. The trial was so successful that the Hut's and Hare's decided to go ahead with the system along their entire lake front. Jim explains the principle behind the system's design. "We must keep the constant lapping of the water and rave action from hitting the bare banks of the shoreline. That will stop the erosion.' This is done by installing the Vegetated seawall at the foot of the bank. The seawall at Sycamore Lake consisted of fust placing a rock roll along the bank and topping this with a tour fiber roll. Plants, were then estab- lished in the coir roll and in the bank behind the fiber roll. The rock roll was assembled on the site by first setting two parallel rows of stakes at the base of the bank. The rows were about 14" apart and in 2' -deep water. The rows were parallel to the shoreline. The 2"x 2"x 48" stakes were 1' apart in the outside row and 2' apart in die row nest to the bank. A biaxial geo-grid was placed in a N" shape between the rows of stakes. S T R E A M B A N K STAB I LIZATION . - -- chad rr!nela c' - . .: eil what happened next. started.
