Ms. O'Dea reviewed the Illicit Discharge Ordinance page by page looking for comments and questions from Board members. Page 2, Add: construction waste under Pollutant. Entry Upon Private Property: The City shall be permitted to enter and inspect all commercial buildings and land. This needs to be defined stated Ms. O'Dea. Mr. Asleson stated the City attorney should look at the document. Ms. O'Dea stated this needs to be narrowed. Ms. O'Dea stated Mr. Asleson is looking for a Board recommendation at this time. Ms. Bor moved to pass the document forward to the City Council. Mr. Brown seconded. Recommendation to forward to the City Council carried unanimously. 7. DISCUSSION ITEMS 1. Early Childhood Nature Area /Alex Rafferty and Arlene Kringle Alex Rafferty and Arlene Kringle were in attendance to present Agenda Item 6A regarding Early Childhood Nature Area. Mr. Rafferty is working on his Eagle Scout badge. He will be putting together three outdoor classrooms. The first area will be benches and chairs. The second will be a climbing area, somewhat like a playground. The third area will have segments of trees sunken in the ground to create a floor. Ms. Kringle stated she has attended seminars at the Department of Natural Resources and University of Minnesota on how this project will benefit children. Ms. O'Dea questioned if there would be native seed planted in this area. Mr. Asleson stated it has been done. Mr. Rafferty and Ms. DeHaven exchanged contact information in regards to Ms. DeHaven having a contact to donate wood chips for this project. DRAFT MINUTES • • • ENVIRONMENTAL BOARD MEETING JUNE 30, 2010 Ms. Andrzejewski questioned if there would be plastic installed. Mr. Rafferty stated there would not. The cracks will be filled with sand. Ms. O'Dea stated the Board expresses their support of the Early Childhood Center's effort to create the outdoor classrooms. Mr. Brown made a motion to approve the project. Ms. DeHaven seconded the motion to approve the project. Motion carried unanimously 2. Peltier Lake Heron Colony Mr. Asleson and Tim Payne, Natural Resource Specialist, were able to make a trip out to Peltier Island on June 22. Mr. Asleson stated there has been extensive growth which made it very difficult to view nests. They counted at least 19 chicks. The island is in need of up -keep to protect the birds. He is proposing to perform maintenance on the island. Ms. Bor stated in past winters when the ice is no longer safe, would be the time to do a good clean through on the island. Mr. Asleson stated several nests have failed because of bridging. Ms. Bor stated she would like Mr. Asleson to find a time to clean up the island at an appropriate time that would not disturb the birds. Ms. Bor would like the Environmental Board to personally send a letter to Anoka County to have new signs installed on the island. Mr. Asleson stated there are new signs that are fluorescent orange instead of white. It was stated that one year after the raccoon eradication the raccoons are back in full force on the island. It was mentioned that perhaps we could stipend someone to trap on the island for a few years, such as the DNR. Ms. Bor would like to explore this idea and see what would be available. Mr. Brown controlling and trapping is very expensive. He stated this is a constant debate. Ms. DeHaven questioned if the herons migrate to the Gulf. Ms. Bor stated yes. Ms. Bor will draft a letter and present it to the board to send to Anoka County. The Board will review the letter in July if there is a meeting. If not, the letter will be mailed out. 3. Emerald Ash Borer Update Mr. Asleson attended an EAB seminar on community based preparedness plan. DRAFT MINUTES 3 ENVIRONMENTAL BOARD MEETING JUNE 30, 2010 Ms. O'Dea stated she read an article on parasitic wasps that seem to have had a positive effect on EAB. Mr. Asleson stated there has not been a conclusion on this at this time. 4. Community Gardens John Norblom, Master Gardener and City of Lino Lakes' resident was present to update the board on community garden projects in other communities and to discuss Lino Lakes' future community garden. This project is one of the Environmental Board goals. Mr. Asleson stated he wants to set up a game plan to be followed. He stated it would be a good idea to set up a public meeting just before school starts and invite residents to attend. Mr. Norblom stated he could be in attendance for this planning meeting. He presented an agreement from the American Community Garden's Association to give an idea of what guidelines would be useful to follow. Ms. O'Dea stated we need to use various methods to advertise to the public to see how many people would be interested in a community garden. It was stated there should be advertising on the City's website, fall newsletter and contact a local paper to see if they would be willing to donate a space for advertising. Mr. Asleson stated he would email a link to the Community Garden Association to board members. 5. Addition: Chestnut Tree — Dave Roser Mr. Asleson presented resident Dave Roser's proposal regarding harvesting seeds from his chestnut tree this fall and donating the seeds to the Environmental Board and City with the hope to have a suitable spot to start a grove of chestnut trees in Lino Lakes. Ms. Bor stated growth tubes could be put in her meadow to see if the trees will take. Mr. Asleson stated he could find a few areas in the City for this as well. Ms. Bor stated Peltier Island may be a good place for this also. It was decided that the Board will accept the seeds and determine where to plant. 6. Addition: Storm Water Stenciling Mr. Asleson stated an Eagle Scout contacted him regarding a storm water stenciling project. He stated there are 739 storm drains in all. He stated this project may be too extensive for the Eagle Scout. He stated he has a meeting with him next Wednesday. The stencils and paint have been ordered. 7. Addition: Pond D DRAFT- MINI) ITES 4 • • • ENVIRONMENTAL BOARD MEETING JUNE 30, 2010 Mr. Asleson stated Pond D off of Sherman Lake Road and Pheasant Hills Preserve has been monitored and data has been collected from two local gentlemen regarding recycled carpet that is used to take up phosphorus. The carpet was put in Pond D today. This is a new technique and all will be interested to see the report of reducing algae growth. 8. ADJOURN It was noted that the next meeting of the Environmental Board will be on Wednesday, July 28, 2010 at 6:30 p.m. There being no further business, Ms. DeHaven moved to adjourn at 8:10 p.m. Ms. Andrzejewski seconded the motion.

The motion for the adoption of the foregoing ordinance was duly seconded by Council Member and upon a vote being taken thereon, the following voted in favor thereof: The following voted against same: Whereupon said ordinance was declared duly passed and adopted. • ENVIRONMENTALLY SENSITIVE AREA No Access Permitted During Bird Nesting Season March 15` to September 1 :z • • Anoka County Park Ordinances Enforced • 7uly 28, 2010 City of Lino Lakes, MN Emerald Ash Borer Management Plan Purpose: -�a The provisions of this management plan are intended to provide a cost effective and culturally acceptable method of management for the outbreak of Emerald Ash Borer. The death of all the ash trees in the City of Lino Lakes will have a detrimental effect on home values, quality of life and environmental benefit. The goal of this plan is to mitigate the impact of EAB as much as practical, to residents and City Ash trees. Introduction: Emerald Ash Borer (EAB) is an invasive, non- . ive, introduced pest that came into the USA from ports in Detroit Michigan. The in _ indigenous to China and is suspected to come into this country in packing crate B most likely existed in Michigan for at least 5 years before a plant pathologist not somethi • wrong with their Ash Trees in 2002. All efforts in Michigan to stop this insec ' e f It is now estimated that EAB can travel up to 4 miles by its self, or an ave 10 miles with human help. Humans help this insect get around to new areas mby firewood transport. With • only 6 or seven years of study and research, manager is time are unable to stop this insect. Scientists • - :; ow that once established in a h , all of the City's Ash trees will be killed in five It will be perhaps 20 years mum until effective controls may be a Minnesota has more A illion) than any other state. This number does not include the trees plan i vfr rks and along street scapes. The City of Lino lakes has approximately 32 trees ik > and 598 Ash trees on street boulevards. �sw There are also 157 Ash trees o ..tier Islan• that have supported Great Blue Heron nests in the past. Preliminary rem • sensing from the Minnesota Department of Natural Resources estimates 10000 �" trees overall in the City of Lino Lakes. There are three options (other than doing nothing), or combination of these options that cities can decide to follow. First, a city can remove all of their Ash trees. If the trees are not removed, unsightly and hazardous trees are left in the landscape. Secondly, a City can remove and replace the dead ash trees with another type of tree, thus mitigating the benefits of the lost trees. Third, a City can chemically treat the trees with an insecticide for an indefinite amount of time. A city can also do a combination of any of these options. The following highlights each option. • 1. Remove all Ash Trees: All Trees will die in 5 years so removal costs are associated with the city or a contractor removing all trees in 5 years. This plan July 28, 2010 has the lowest out of pocket expense. This plan also causes the greatest losses to aesthetic and ecological value that the Ash trees provided for Lino Lakes. 2. Replace all Ash trees. This option replaces every Ash tree with a new tree that won't get Emerald Ash borer. This plan is the least costly way to manage the Lino Lakes Ash forest and allow it to regain its former size. 3. Treat the Ash trees with insecticide. This plan has the lowest annual out of pocket costs, but it has the greatest cost over time t also produces the largest remaining forest over time. Research demonstr f at insecticides can protect small trees < 12" in diameter until they reac ` nch diameter. Effective treatment of larger trees would require eit m. requent application, or a higher dose of inspective. Research as of 8.2010 s one application of insecticide will treat a tree for at least 3 years. Treating at least the middle range of tree size also gives the CI e to spread our losses over a much greater time period, and possibly eliminate ou ,., es for treated trees. Natural controls with r�< ;. ,� c and predatory insects, genetic section and manipulation, all take time. Th d time to achieve victory in one of these areas is 20 years minimum.

Disposal Since all trees within an infected c will be severely transport limited by quarantine, It is recommended that two diseased tree stock pile sites be designated in the City. These sites would be open to the residents of Lino Lakes to dispose of their dead Ash trees. Trees would be allowed to stay on site until such a time that there would be sufficient volumes for tub grinding by St Paul District Energy. Suggested stock pile sites are the north western corner of the old city hall site, and the athletic complex land on Centerville Road and Birch. Maintain an open invitation to better -use utilization of Ash wood.. Public Information Connect to the public by newsletter articles, web page, kiosk information booth and possibly PSA's on local cable TV. July 28, 2010 Partnerships Share resources with other communities where possible. Investigate the use of marshaling of materials on a common interest basis. • •
