Village Hills Preliminary Plat Asleson reviewed the background material. The project proposal was a 3.75 -Acre commercial development located east of Hodgson Road on Birch Street. The developer was proposing to build three commercial buildings on the site. A tree preservation plan was submitted because there were some trees off site. The developer had been denied an exemption of an irdentawetland, and had not received a permit with the RCWD.

Asleson continued that there was a ter design. The area off site behind the houses cl a high ecological value zone. Donlin stated she iieedeel laification for the future Ware Road extension. Asleson answered that the road was the entrance to Spirit Hills 1st Addition and would connect to Hodgson Road. Donlin pointed out it appeared that the Attachment 2 Erosion Control Plan used the same key for all the items. Asleson indicated that it was difficult to read. Donlin inquired about the lighting, asking for confirmation that it was low impact and no spill. Asleson answered yes, but that the Board should still make the recommendation. Grundhofer noted that the plan called for 40 lights on site, and considering the number of lumens it would be equivalent to 900 light bulbs. She asked how high 2 DRAFT MINUTES • • • • ENVIRONMENTAL BOARD MEETING APRIL 24, 2002 the poles were going to be. Chair Kukonen stated that the standard was 15 -foot poles. Donlin mentioned that she could not clearly identify the locations of the lights, and that she was dissatisfied with the lighting plan. She also inquired whether on meant on at all times, or something else. Asleson indicated that she and the Board should make a statement of their concerns. O'Dea stated that there would have to be enough light for parents to drop off and pick up their children in the dark. Donlin suggested that the track record of the developer might show that excessive light was a concern. Chair Kukonen stated that the number of piing s as near the City minimum.

The day care site however would be near a natural environment lake and an important watershed area. Asleson stated that the Board could show concern over the gas station at that location. Chair Kukonen submitted that perhaps vegetative buffering could minimize the impact of a possible spill. Donlin inquired about the City's requirement of effective buffering and its application in the northern edge. Asleson stated there were no other plans other than on the Landscape Plan, because a sidewalk will be there. 3 DRAFT MINUTES ENVIRONMENTAL BOARD MEETING APRIL 24, 2002 Asleson noted the use of hackberries along the Northern edge. Donlin responded that they were not thick enough to block the view and suggested berming. Asleson explained that hackberries take 3 -4 years to become established. Schneider liked the hackberries because they were good for wildlife, and were a good long -term choice. Grundhofer noted that they were planning to use maples on site. Grundhofer mentioned landscaping fennel reed grass, but she could not find any information on it. Asleson indicated he did not think it would be a problem, but would check. Chair Kukonen reviewed the recommendations from tb Board that included: • Work with the RCWD and City staff • Lighting should have no spillage, be do the number of fixtures. • Work with City staff to create buffed • Replace maple with some other a • Reduce impervious parking spas Netlawn pervious parking. • Concern over the gas station and the; as a lake protection zon a1. having ecies and maximize the use of e reduction of of a spill into the area defined ogical value.

Schneider. complia obscure to be a number in the recommendation to ensure recommendation, and not to leave it at the B. Raske Builds = ems, Inc. Asleson reviewed the background. The Board had reviewed the plan at the October 1, 2001, meeting, so the recommendations made at that time still apply. The only item left to review was the landscaping plan. His only concern was the small cedars on the site, they were going to be removed, but he would like to see then used elsewhere on the site. He highlighted the standard recommendations, and the Board recommendations on Attachment 1 Options. Donlin expressed concern over the surface water, inquiring if the owners of the two lots were going to work together. Asleson indicated that the wetland was a pond. 4 DRAFT MINUTES • • • • • ENVIRONMENTAL BOARD MEETING APRIL 24, 2002 Chair Kukonen stated that the pond was very large. Donlin explained that the concern was for the nearby trees, and the possibility that the pond will increase in the swale to the trees, and they would be lost. Chair Kukonen suggested a replacement schedule if the trees were lost. Donlin indicated that in the October 1, 2002, recommendations, the 5th bullet asked for a replacement schedule to the expanded wetland. Chair Kukonen commented on reducing the number of parking spaces to the lowest number possible. He asked if anything changed. Asleson stated he would look into it. Schneider inquired who was going to ensure tha implemented.

She received a permit, and made calls an hour before the burn to ensure that there was no fear or false alarm. Apparently there were many 911 calls. O'Dea inquired about the possibility of signage to warn people. Donlin stated that the Fire Departments from White Bear Township and Centennial came to her house, while the permit was through Centennial. Grundhofer indicated she also had a permit for burning through Centennial Fire Department for the same day. She was also confronted by the firefighters, and she stated she had a permit. Evidently no note was written at the station to warn the firefighters on duty of the two prescribed burn permits. 5 DRAFT MINUTES ENVIRONMENTAL BOARD MEETING APRIL 24, 2002 Donlin expressed concern for her septic tank, because it was driven over by the fire truck. She added there was a need for better coordination on the permit process. Chair Kukonen mentioned that prescribed burns might be a good topic for public education in the City Newsletter. Schneider added the issue could also be featured on the website. D. Greenway Grant Land Classification with Chris Ward Mr. Ward reviewed the history of the project. 1.5 -2 years ago the City received a grant to do the land classification. Recently theyavee eived another grant. Once the Landcover was completed, the bald ce ft project would need to be finished by June 30, 2002. The applicatio vailable to the City include Landcover inventory, G.I.S. analysis, and cit g public outrea He introduced Rich Biske who would also be pie; Mr. Biske presented a slide show to illustrate the posh t tlities with the Metro Greenways Program. He indicated the c�za ge was to fwd significant communities and develop management based on the systems. He showed an example of presettlement vegetation aid t c rem tit g natural communities.

Mr. Biske identified th ` "eenway corridors and hubs. He indicated the linking of those greenways across municipalities was a challenge. Mr. Ward explained that the green areas were open to interpretation. Mr. Biske pointed out that there was a need to establish options for restoration or easement. The goal was to move development to presently disturbed sites. They could also provide technical assistance to enhance and restore land. People needed to come together to protect a corridor. He asked the Board if there was a citizen forum that they could address. Donlin appreciated their efforts, because many greenways were located in developed areas. She noted a recent series called green growth that received a lot 6 DRAFT MINUTES ENVIRONMENTAL BOARD MEETING APRIL 24, 2002 • of interest and several letters to the editor. Mr. Biske concurred and added that native grasses needed more exposure. • • Mr. Ward stated that they needed the most effective means to connect with residents and to satisfy the grant requirements as well. Grundhofer pointed out at the Earth Day celebration, children came to the booths to receive stamps, while the adults were not involved or asked questions. She suggested that perhaps fliers could be put in newspaper boxes of the targeted areas. Mr. Ward responded that another option was at the community -wide level. In Blaine, they found the concept scared people because they thought the government wanted to take their land. The groundwork needed to be laid slowly.

Councilperson Carlson, icated that the City of Centerville had asked for a meeting with the City of Lino Lakes. Schneider asked for clarification, if they wanted help with education. Grundhofer inquired whom they wanted to have for a first contact. Mr. Ward stated that if there was enough interest, it could be a discussion of what is a Greenway, which could be geared to the landowner. Asleson responded that the elected officials could be brought together. Mr. Ward indicated that the beginning of June would be a good time. 7 DRAFT MINUTES ENVIRONMENTAL BOARD MEETING APRIL 24, 2002 Schneider suggested that the topic for discussion should draw people, and urged the use of a word other than Greenways. Asieson suggested the public hearing forum as a possibility. He inquired about the need for more funding. Mr. Ward discussed the need to clarify that the City was not interested in taking someone's land, but land acquisition through purchasing chunks in a proposed greenway was a possibility, as well as several other options. Asieson proposed an example that the City required a preliminary plat. The question then becomes can the same number of units be fit into the site in light of the identified wetlands. Mr. Ward agreed that th © njtment required a plan, but the tools were better now than ten years m :o Chair Kukonen stated that the City had detnank the .' `' amt of Viand required for a septic system that determined the size Mr. Ward indicated that concentrated co m unities � d result leaving larger open space, if perpetual conservation ea ext ent were p t nto effect.

A discussion ensued coerning the logistics of a meeting with elected officials and possibly representatives from the City of Centerville, before the deadline of June 30, 2002, but leaving enough time to finish the Landcover Classification. B. Peltier Island Update Asieson stated that a joint powers' agreement had passed, and was now in the 30- day waiting period. Donlin stated that the birds were back. Before the big snowstorm, there were 16 pairs, but they have left. The DNR did a fly over and counted 70 egrets. She indicated there were misconceptions. There was no ordinance, so the only 8 DRAFT MINUTES • • ENVIRONMENTAL BOARD MEETING APRIL 24, 2002 • compliance was peer pressure. She added that there was a nesting eagle sighted, and there appeared to be harmony among the various species, not competition. Asleson noted that the Bell Museum was interviewing several people for an article in the Bell Museum newsletter. Donlin mentioned that she was going to participate in a DNR sponsored crane count in Carlos Avery tomorrow. Asleson suggested that they should count in the City, because he had seen several pairs. Grundhofer indicated that she had visited the nature center in Detroit Lakes. C.

Russian Baptist Church, Site Plan Review Chair Kukonen indicated that he spoke with representatives from Rice Creek Watershed District. They had issues that were essentially administrative, there was no planned site visit, and the issues concerned infiltration and the two ponding areas. Asleson reviewed the background, analysis and recommendations from the green sheet. The Church was asking for a Conditional Use Permit (CUP) on 4.61 acres because it is in a rural zone on Ash Street and Baldwin Lake Road. A portion in the Southern part of the site had been filled, while the Northern part was hydric. The Land Classification Inventory indicated Long Grasses and Sparse Tree Cover in the North with a flood plain encro > ng ,and Aspen Forest Saturated in the South.

Staff disc n addition, fu1 Donlin expressed concbout several issues. Did the septic system include a primary and secondary system. , Impervious surfaces should be minimized. She did not understand why the Church refused to accept grant money for a better system. Asleson indicated the landscape plan needed modification with changes necessary for the Sugar Maples and Colorado Green Spruce. The lighting plan conformed to the City standards. Staff recommended approval with changes including: • The submission of a tree inventory and preservation plan, maintaining the buffer around the wetland. • Increase infiltration around the parking areas. 2 Draft Minutes • • • • ENVIRONMENTAL BOARD MEETING MAY 29, 2002 • Change the Colorado Spruce and Sugar maples to different species, with plantings out of the water areas in the infiltration areas. • Use green parking in future expansion areas and out of tree area around wetland. • Use sand or organic filtration with the septic system. • Use the native seed mixture used in the City of Lino Lakes. O'Connell inquired about a sewer on Ash Street. Asleson responded that they would have to run a pipe. Grundhofer asked if the zoning allowed for a Church. Asleson answered that it was presently zoned rural.

Asleson sponded that the septic system would be able to accommodate any functions taking place in the building. Donlin noted the project was not finished. She was concerned about the use of the building. She indicated it was not researched well. Chair Kukonen inquired about another chance to review the site plan. Asleson stated that there would probably be another chance. O'Connell stated the plan had loosening of the soil, she questioned if the depth was enough. Asleson stated that the subsoil should be uncompacted, fencing off infiltration areas. 3 Draft Minutes ENVIRONMENTAL BOARD MEETING MAY 29, 2002 O'Connell asked about the necessity for concrete curb and gutter. Chair Kukonen inquired about the sand septic systems, were they mound systems. He asked for additional recommendations from the Board. Schneider questioned if there was a twelve -month guarantee that the plants would live. Chair Kukonen summarized the recommendations he had noted from the discussion: • Deep till seven to eight inches to protect soil areas, while fencing all infiltration areas and the use of low impact equi] • Schedule landscape installation and maintenance for 3-5 years. • Elimination or reduction of future parking, amuse pervious parking.

Anoka Conservation District Mr. Biske gave a background on greenways. He had done an open space design. Cumulatively, to put the data into a binder format for easy reference would be beneficial. He then distributed to Board members a brochure and the grant plans for further explanation. Draft Minutes a • • • ENVIRONMENTAL BOARD MEETING MAY 29, 2002 Chair Kukonen asked if they needed an open house before the end of the month. Mr. Biske indicated that a meeting was planned for June 17, 2002. Asleson stated that the location was yet to be determined, but it would be a joint meeting with officials from the City of Lino Lakes and the City of Centerville. Mr. Biske explained that he did not have the raw data, but would have them identified by the end of the summer. He inquired about the availability of a couple of Board members to identify the process. He pointed out that there were good examples in Anoka County. Much of the raw data would be obtained from Mr. Huvseth, with the next step to identify the parcels, which could then be built upon. His goal was to identify the greenways, which could go beyond open space. Chair Kukonen questioned the success rate responded that the success had been good, space design, easement, or transferring de th landowners.

Asleson stated that C vas seeking to fill an intern position for the summer, with the minimum qualification of a tree inspector license, environmental course work, and knowledge of plants. The wages would be $10.00 per hour. The duties included inspecting, answering calls, follow -up, creating public information, perform basic tree maintenance, and public relations. Chair Kukonen inquired about the funding for the position. Asleson responded that the City was funding it for 40 hours per week, with no benefits. He added that it would be nice to study the health of the wetlands in the City. Halen inquired about the status of the house on Birch Street, was it preserved. Asleson stated that the owner still resided there. 5 Draft Minutes ENVIRONMENTAL BOARD MEETING MAY 29, 2002 C. Zoning Code Task Force Update Donlin stated the group had been having positive group discussions on conservation planning, although there were various definitions, and was unpopular with some members. She and Chair Kukonen were standing for preservation. Chair Kukonen gave an example of the differences of the R -1 plan with 70 lots on 34 acres. The R -1X plan had 58 larger lots on 34 acres. The final plan R -1XC had 58 lots that had been shrunk to the size of R -1, to allow for open space. It still fell short of the 50% goal that had been established. In addition, it would not be economically feasible because of the cost of the utilities, and the examples found were not confined to city water and sewage. Thit ltyntensifies the need to seek out land acquisition. Asleson stated one way to attain the goal Program. He also wanted to know who sha 2002.

Halen suggested a listing of native plant landscaping companies. Asleson responded that he has information of many companies, they needed to be compiled into a list and put on the website. He stated that a neighborhood restoration was taking place in Birchwood Acres located East of Mustang Lane and the South side of Palomino Drive. Within a week a planned kill would take place. Grundhofer suggested showing the steps in the restoration of a wetland with pictures and to put it on the website. 6 Draft Minutes • • • • • • ENVIRONMENTAL BOARD MEETING MAY 29, 2002 Asleson stated he was planning to meet with four fourth grade girls who wanted to discuss water quality, lakes, and prairie plantings in Lino Lakes. He indicated that there were opportunities at the Middle School also. Donlin mentioned she had an interview with Wargo Nature Center for a part-time naturalist, so if she was offered the job, she could be a link between the Board and the Nature Center. O'Dea questioned the licensing of tree trimmers or certified arborists, because she had contact with a company that was going through her neighborhood trying to trim oaks. Asleson responded that some cities did license them, but in the yellow pages some tree trimmers stated that they were certified arborists. Grundhofer indicated that she looked for ce y. ied, cen ed, bonded, and insured. O'Dea suggested another project for the ii buckthorn. Asleson answered that he kno work with the buckthorn issue. the was willing to O'Dea submitted that people like buc ed a thick hedge. Grundhofer added that the berries at Donlin mentioned that her farm;could be native, invasive species in the,, -partme e, because they had every non- al Resources booklet.

Asleson inquired about the greenwa the Anoka Conservation District, because there were several education opportunities through them on greenway planning. Donlin noted the Lake Peltier monitoring was ongoing. Chair Kukonen indicated it could be listed as a sidebar. He stated that the work on ordinances was already happening with the Task Force. O'Connell pointed out that the fall City Newsletter should be on buckthorn. Kukonen summarized the goals that ranked as most important: • Work with the Anoka Conservation District • Public education on non - native, invasive species. • Seek funding for land acquisition. 7 Draft Minutes ENVIRONMENTAL BOARD MEETING MAY 29, 2002 Asleson stated that Target would give money for public education. Donlin expressed dismay at the removal of the oak stand. She pointed out there were guidelines to follow, and saw no evidence of Target following through with the recommendations. She urged the City to seek retribution. Asleson noted there was a need for an explanation of what happened. Mitigation would have to take place off site. Schneider questioned if the goals of public information and a project could be combined into one goal, because the project was alreadytaking place, it just needed to be publicized. Asleson urged E -mails when meeting with groups, s that Board members could attend. 7. DEPARTMENT REPORTS A. Forestry Asleson stated that they have the p1 : dealing with the oak wilt. B.

Motion passed unanimously. Transcribed by: Brigette Blesi TimeSaver Off Site Secretarial, Inc. Draft Minutes Agenda Item 5A Environmental Board Meeting Date: June 26, 2002 Topic: Stoneybrook Development/Preliminary Plat Background: The following minutes are from the March 27th Environmental Board Meeting. At that time the Stoneybrook Preliminary Plat was discussed and passed on to the Planning and Zoning Board. ACTION ITEMS A. Stoneybrook, Preliminary Plat, Rezone, MUSA/Comp Plan Amendment Asleson indicated that there were three development areas. He reviewed the background material. The property was guided for low- density sewered residential development in the Comprehensive Plan. The developer was requesting MUSA allocation, and rezoning from R -Rural to R -1X -Low Density Residential, and approval for a 111 -lot subdivision. There were 19.2 acres of wetland, with 2.06 requiring mitigation, which would be accomplished on site, and 58.87 acres of upland. The site was very wet, and infiltration techniques were limited, so water quality design was important. The water basin areas should be protected from compaction and planted with a buffer of native plants. Basin filtration capacities should be enhanced with organic bed establishment in flow areas, such as an organic pond area. Schneider inquired if the recommendations were binding. Asleson responded that they were only recommendations. Grundhofer pointed out that there was a development on Ward's Lake adjacent to this development, and asked if they were both aware of each other's impact and the combined impact. Asleson indicated they were being dealt with individually. Asleson continued reviewing the background material. The soil was very insensitive to ground water pollution, except for a small area in the South East comer that is in the Vadnais Lake Area Watershed District. Additional water volume discharges should be minimized. A sequencing plan and a management plan including a 3 -year contract with a landscaping company should be submitted. He urged that no soils should be hauled off the site or brought on the site without permission from the City. The sequencing plan should indicate responsibility for cleanup after the last house was completed including the fencing. The landscape- screening plan was submitted for Birch Street, but staff had concems about Colorado Spruce and the maple was not hardy for the soil. Grundhofer questioned if there were any acceptable conifers. Asleson stated that the only native conifers were white pines located in northern Anoka County, but were not native or adapted to this area. He conceded that a white spruce might grow if they wanted a spruce. O'Connell inquired about whether willows were native. Asleson indicated the water willow was possible. Asleson stated water filtration was important. In addition, he recommended the developer should escrow money. Chair Kukonen reviewed the Site Plan Review process. First there was a staff review, then the developers would present, followed by a dialogue with the Board. Concems he had were buffering in the North East corner near Lots 4 and 5 in C, and the greenway should not be encroached upon. Asleson said the areas of buffering should have signage and be covered in the covenants. He noted that they needed to be careful of the water table. Chair Kukonen identified an inconsistency in the wetland inventory possibly due to the draining and ditching. He attempted to walk the site, but it had no trespassing signs and barbed wire fences. Halen asked for a brief description of buffering. Chair Kukonen responded that it could be several things such as a berm for noise pollution as in the intersection of Highway 96 and Lexington, but it could also be a wetland for water absorption. Asleson noted that the number of houses was reduced to about 102. Grundhofer inquired about the effort to have houses located in the Stoneybrook Flood Plain. Halen questioned if the houses located in the flood plain needed to be approved. Asleson responded the approval would be based on the soil and the housepads. Chair Kukonen explained the Army Corps of Engineers would be looking at the flood plain in relation to the elevation and the 4 -foot leeway. Asleson advised the Board to allow the Army Corps of Engineers to deal with the issue. He added that no one raised the issue of importing soils. Chair Kukonen asked if there was no requirement for park designation due to the outlots. Asleson responded he did not believe so, if not land possibly money. Schneider inquired about the direction that the watershed flowed. Asleson answered that they all went into ditches. Grundhofer expressed concern over the preservation of the oak savanna area. Asleson explained that it was actually off site and should not be impacted by the changes on the property. Chair Kukonen submitted that they should ask for an overlay or a PDO, and ask for more open space. He was concemed about the streetlights, but the City cannot ask for a light site plan for residential. Grundhofer stated that because of the presence of wetlands, the City should ask for low impact shoebox lighting. Chair Kukonen read comments submitted by Donlin who could not attend. She pointed out that the site plan appeared to fit into the premature subdivision designation. She also expressed concern over the number of houses, in light of the 147 goal for the year. Donlin also submitted that it could cause traffic concems on Centerville Road. She mentioned the Saint Paul Pipeline area should not be developed. Finally, she stated the site was one of the remaining agricultural lands, and inquired about other options. Schneider inquired about it being a reasonable option. Chair Kukonen answered that legally the time clock begins when a developer begins the process, if the City does not respond within the 60 or 120 -day period, it would pass. The Board could ask for it, but the City could not require it. Schneider asked for confirmation that it would be better to make recommendations on the plat than to deny it. Chair Kukonen indicated that most often it was. • • • Chair Kukonen stated that a road was proposed over the culvert owned by the St. Paul Water Utility. He thought the plan should be denied with recommendations. He added that things had been approved in the past. Asleson indicated that the City decides after it goes to the Planning and Zoning for reviewal. Schneider questioned if the culvert with the proposed street over it was referring to Street B. Chair Kukonen responded that the culvert was from Vadnais. Asleson clarified that the Pipeline easement was not a greenway, but a trail connection. Chair Kukonen called for a motion. He reviewed the Board recommendations to be added to the staff recommendations: 1) Deny and contact the St. Paul Regional Water Utility and the Vadnais Lake Watershed District. 2) Provide Buffering for pipeline easement in the northeast comer lots. 3) Street lighting should be downward focused, no spill. O'Dea suggested more open area, where 50% or more should be preserved as open space not including wetland mitigation. She proposed an additional 17 acres should remain undeveloped, and encouraged clustering. Asleson submitted signage on the buffer areas and language in the association's covenants. O'Dea addressed the screening on Birch Street, and inquired about the possibility of promoting non - linear plantings. She also asked if the ditch was going to remain or if it would be altered. Chair Kukonen inquired if would he consider asking for a PDO to preserve a 17 -acre additional open space, as long as the developers were requesting a re- zoning, and follow the principles of development from the Handbook for Environmental Planning and Conservation Development. Asleson noted that signage should be placed on the buffer boundaries to indicate that buffers did exist, and covenants should be established with the homeowners' association prohibiting encroachment. Schneider asked about the site's chance for approval. Chair Kukonen responded the site plan would go the Planning and Zoning Board, and then to Council. He added that the Environmental Board was reviewing the plan because it was submitted prior to the moratorium taking effect. Asleson pointed out the Rice Creek Watershed District usually met the same night as the Environmental Board, so he had tried to meet with them earlier. Schneider asked for more information about the role of the Army Corps of Engineers. Asleson answered they would be involved if there was a headwater located on site. Schneider asked for a definition of MUSA allocation. Chair Kukonen responded that it was City water and sewage, and was dictated by the Metropolitan Council. Asleson added that it affected the capacity to deal with sewage. Grundhofer inquired about when it was going to be approved. Chair Kukonen stated that the Surface Water Management had already been approved. Asleson added the Rice Creek Watershed District had yet to be approved. O'Connell posed the question about the possibility of asking the developer to communicate with Ed Vaughn. Asleson spoke concerning the combined impact of the two developments. The Minnesota Pollution Control Agency controlled the discharge rates. The developer was going to try to keep the water on site, or to use filtration. O'Connell made a motion to pass on the denial and the staff and Board recommendations: • Contact the St. Paul Regional Water Utility and Vadnais Lake Watershed District. • Buffering for Pipeline easement in the northeast comer lots. • Street lighting should be downward focused, no spillage. • As long as the developer was requesting a re- zoning would he consider a PDO to preserve an additional 17 acre additional open space. • Signage should be placed on buffer boundaries to indicate buffers exist, and covenants should be established with the homeowners' association prohibiting encroachment. Halen seconded the motion. Motion carried unanimously. The Planning and Zoning Board tabled the Preliminary Plat Hearing because of platting issues. The Preliminary Plat is before you again. Not too much has changed. The Rice Creek Watershed however has made a recommendation (not a requirement) that the street width be reduced to 29 feet instead of 32 feet. Please find the most recent Plat Proposal (Attachment 1). Analysis: Reducing the street width from 32 feet to 29 feet would reduce the amount of impervious area in the development by about 23,000 square feet. I agree with the recommendation. However, there are no adopted standards under the subdivision code providing for this, and there was concern from public services regarding street plowing and fire and pedestrian safety. Chief Bennet indicates the Fire Department needs 20 feet for access. A 20 -foot road would restrict parking to one side of the road in order to achieve this 20 -foot fire access. Please refer to attached street design section from the Center for Watershed Protection for more information on road design case studies (Attachment 2). I stated at the previous Environmental Board review of Stoneybrook Preliminary Plat that Stoneybrook is a very wet site. There is little room for infiltration, but plenty of room for improved design in filtration. Residents living in this development are going to experience "soft- and - mushy" situations. I think the developer should go beyond standard disclosures and inform residents before they sign purchase agreements on this situation. An informational brochure describing the buffering, and soft and conditions that may be experienced should be given to them. • Options: The March Environmental Board recommended that the Plat be denied. Please see issues listed above. The Environmental Board issues were forwarded on and many of them addressed. (Attachment 3). I would recommend adding the two above issues in "Analysis" as additional considerations. Recommendation: Environmental Board Comments: Attachments: 1. Preliminary Plat Drawings - Stoneybrook 2.

These widths should be based on traffic volume. CURRENT PRACTICE Many communities require that residential streets be 36 feet wide or more, even when they serve developments that produce small volumes of traffic. These wide streets result from blanket application of high volume and high speed highway design criteria, as well as a perceived need to supply both on- street parking and unobstructed access for fire trucks. However, residential streets are often unnecessarily wide and the excessive widths contribute to making them the largest single component of impervious cover in a subdivision. Narrowing residential street widths can help reduce the amount of impervious cover created by excessive street widths requirements. RECOMMENDED PRACTICE Several national engineering organizations have recommended that residential streets can be as narrow as 22 feet in width (AASHTO, 1994; ASCE, 1990) if they serve neighborhoods that produce Low traffic volumes (less than 500 daily trips, or 50 homes) In several communities such as Buck's streets with success (see Table 1.1).

PERCEPTIONS AND REALITIES ABOUT STREET WIDTH cernsabout parking, safety, fire Any effort to narrow residential streets will need to satisfy community concerns P truck access, congestion and other factors. Much of the s these concerns. available research profiled in Table 1.2, however, suggests that careful design of narrow streets can address Parking Demand The need for on- street parking is often used to justify wider residential streets. siont, 2 spaces can usually that 2 or 2.5 parking spaces be provided for each home.

Street Width and Safety The potential for increased vehicle- pedestrian accidents is often ited for not safer than narrower streets. Many studies, however, indicate that narrow residential streets may Federal Highway Administration (1997) noted that narrow street widthhs tend 19o92 reduce her vehicle which drivers travel. This finding has also been ndte noted by t eotent�al accidents. Slower speeds also reduce the provide drivers with more fime to react p P severity of injuries sustained in accidents. Fire Safety Another common impediment is the perception emergency vehicles, particularly fire vehicles. needed to ensure access. However, a number eighteen feet (Table 1.3). that narrow streets do not provide adequate access fc The conventional wisdom is that very wide streets ar of local fire codes permit roadway widths as narrow a Principle No. 1: Street Width Table 1.2: Perceived Impediments to Narrow Streets 1. . Narrow streets interfere with the ability to clear and stockpile snow. FACT: FACT: . "Narrow" snowplows are available. Snowplows with 8' width, mounted on a pick -up truck are common. Some companies manufacture alternative plows on small "Bobcat" type machines (Frink America, 1997). Snow stockpiles on narrow streets can be accommodated if parking is restricted to one side of the street (ITE, 1997). 2. Narrow streets will cause traffic congestion. FACT: Narrow streets are generally appropriate only in residential areas that experience less than 500 trips per day. Street width is largely a function of traffic volume. Design criteria based on volume generally provide safe and efficient access in residential areas (ITE, 1993). 3. Narrow streets do not provide enough room for on- street parking. FACT: FACT: Parking can be accommodated through the use of "queuing streets" with only one travel lane (Bray and Rhodes, 1997; ASCE, 1990). Most communities require some off - street parking accommodation in residential subdivisions. Olympia, Washington requires two parking spaces per dwelling unit. On- street parking is used for visitor parking or parkable vehicles, such as boats (Wells, 1995). 4. Narrow streets can cause pedestrian/ vehicle accidents. FACT: FACT: In a study of over five thousand pedestrian and bicycle crashes, a narrow roadway was a factor in only two cases (FHA, 1996). Unsafe driving speed, • on the other hand, contributed to 225 accidents. Narrower street widths reduce the speed at which vehicles can drive (FHA, 1996). • 5. Narrow streets do not provide access for maintenance and service vehicles. FACT: FACT: CASE STUDY: Trash trucks require only a 10.5' travel lane (Waste Management, 1997), with a standard truck width of approximately 9' (BFI, 1997). In residential neighborhoods, trash collection often occurs simultaneously on both sides of the street; cars must wait for trash trucks to pass regardless of street width. Half ton mail trucks, smaller than many privately owned vehicles, are generally used in residential neighborhoods. Hand delivery of mail is also an option (US Post Office, 1997). School buses are typically eight feet wide (nine feet from mirror to mirror). Both Prince Georges County and Montgomery County, Maryland require only a 12' driving lane for bus access. Furthermore, school buses usually do not drive down every street, but instead meet children at bus stops on larger roads.

'Applicable to grid pattern streets or short cut -de -sacs. ECONOMIC BENEFITS Significant construction cost savings can be achieved by building narrower streets. Construction costs for paving are approximately $15 per square yard. For example, a local jurisdiction currently requires all residential streets with one parking Lane to be a minimum of 28 feet wide. The jurisdiction adopts a new standard: 18 feet wide queuing streets. This new standard would reduce the overall imperviousness associated with a 300 foot road by 35% and construction costs by $5,000. Additional economic benefits include reduced clearing and grading, infrastructure, and stormwater management costs. Long -term pavement maintenance costs would also be reduced. CASE STUDY: LONGMONT, COLORADO (Source: Swift, et al, 1998) The City of Longmont, Colorado is experiencing rapid growth. The quality and type of new development has become an important issue as more development and non - conventional site designs are proposed. Part of this discussion is acceptable residential street design. Over 20,000 police reports were examined to determine the relationship between street design and safety. The study focused specifically on residential streets with maximum ADTs of 2,500. Accidents attributable to poor road conditions or substance abuse were excluded from the study. As shown in Figure 1.1, the study results suggested that narrow residential streets are safer than wide streets. Specifically, streets between 22 to 30 feet in width were found to be the safest. The study further indicated that curvilinear streets were safer than straight streets. In general, the Longmont study suggests that narrow, curved streets can safely be used in residential developments. - 32 - si Principle No. 1: Street Width Figure 1.1: Relationship Between Street Width and Accidents in Longmont, Colorado based on Swift, et al., (1998) Accidents /Mile/Year 12 10 8 6 4 2 0 III Wig 20 22 24 30 32 34 36 38 40 Street Width (ft) 42 44 46 48 50 The curve illustrates the increase in the number of accidents as street width increases. CASE STUDY: PORTLAND, OREGON (Source: Portland Office of Transportation, 1994) The City of Portland investigated the use of queuing streets as described by ASCE (1990) to reduce street widths. The ASCE design assumes that cars will wait between parked cars, or "queue ", while the approaching traffic passes (see Figure 1.2). The new design reduces existing street widths by up to eight feet. Prior to implementing the revised standard, the Portland Department of Transportation studied existing narrow streets to determine if reduced street widths would endanger pedestrians and residents. The findings of this study were: • A bicycle and a car can fit down a 24 foot wide street with parking on both sides. • A dump truck can fit down a 24 foot wide street with parking on both sides. • Fire trucks can easily drive down 26 foot wide streets with parking on both sides. • A fire truck can make the turn from an 18 foot wide to a 20 foot wide road at slow speeds. • Traffic engineers could point to no accident history relating to narrow street widths. - 33 - Better Site Design • The Portland fire chief was amenable to streets as narrow as 18 feet with parking on one side in grid pattern streets or on short cul -de -sacs. • No citizen has charged that fire rescue time was impeded by skinny streets since the inception of this program in 1991 (Bray, 1997) One exception was noted with respect to long roads Leading to cul -de -sacs (e.g., 1500 feet); these streets require two travel lanes for adequate fire vehicle access. The fire bureau therefore retained the right to veto narrow streets on long cul -de -sacs. In the City of Portland, the cost savings realized from narrow streets allowed the city to improve less - developed portions of the roadway which, in turn, encouraged infill development. Infill development refers to development or enhancement within existing urban areas as an alternative to developing surrounding rural areas.

ANALYSIS Proiect Overview Proiect Data: Existing Land Use: Total Site Area Upland Area Number of Lots: Gross Density: Net Density (Upland Only) 78.07 acres 54.73 acres 102 and 6 outlots 1.30 units/acre 1.86 units/acre The project consists of a 78 acre parcel that is currently in agricultural use containing approximately 19 acres of wetland. Surrounding land uses include sewered residential to the north (Pheasant Hills Preserve), unsewered large lot residential to the west and south, and a single family dwelling, pasture and wetland to the east. Land Use Plan: Zoning_ The project site is currently zoned R., Rural District. Surrounding zoning includes R -1X, Single Family Executive to the north, and R, Rural to the east, west and south. Comprehensive Plan Amendment (MUSA Allocation): The City's 2001 Comprehensive Plan is currently being reviewed by the Metropolitan Council. There are approximately 15.7 acres remaining in the City's MUSA bank. An existing development proposal, currently being reviewed by the City (Pheasant Hills Preserve 12th Addition), has requested 4.5 acres. This potentially leaves the City with 11.2 acres until the Comprehensive: Plan is approved by the Metropolitan Council. This is insufficient to cover the requested allocation of 54.73 acres.

Stoneybrook Page 2 Rezoning The City is not in a position to rezone the property until the Comprehensive Plan has been approved and MUSA is available for allocation. Preliminary Plat: Lot Size. The minimum lot size of the R -1X District is 12,825 square feet of buildable land. All lots meet or exceed this provision. However, the buildable areas identified for Lot 7, Block 1 and Lot 6, Block 8 are, in part, bisected by wetland. While the calculations are consistent with the definition of buildable land, the intent is to insure a contiguous land area suitable for development. The applicant should demonstrate that the buildable area includes only that portion contiguous to the proposed house pads. Lot Depth. The minimum lot depth is 135 feet. Double frontage lots are required to have a minimum lot depth of 145 feet. All lots meet or exceed these provisions. Lot Width. The minimum lot width is 90 feet for standard lots and 115 feet for comer lots. All lots meet or exceed these standards with the exception of Lot 20, Block 8. This lot will need to be modified to conform to district standards. Outlots. There are six outlots included in the proposed subdivision. The outlots cover the majority of ponds and wetland areas. It is unclear whether these are intended for dedication to the City or proposed for ownership by a Homeowners Association. The applicant should be aware that any proposed dedication of outlots to the City would not be accepted in fulfillment of park dedication (payment in lieu) requirements. However, if the outlots are not intended for dedication to the City, they should be added to the adjacent proposed residential lots. Setbacks. The required setbacks established in the R -1X District are the greater of the following: 40 feet (Collector or Arterial Street), 30 feet (Local Street), 30 feet (front yard); 30 feet (rear yard), and ten feet (side yard - principal building). The lots have adequate dimensions to meet required setbacks. However, the proposed building pad for Lot 20, Block 8 encroaches into the 30 foot setback for a local street (side yard). This lot will need to be modified to conform to district standards: In addition, pond and wetland areas will mandate a significant setback between proposed building sites and existing homes on adjacent properties. However, the building pad for Lot 2, Block 4 extends to within 18 feet of .the existing wetland and proposed 100 year High Water Elevation. Every effort should be made to maximize the usable yard space on this lot. Street and Block Design. The site has two accesses, one from Birch Street at the existing Pheasant Hills Drive, and one at the Sherman Lake Road intersection. Street A extends southerly into the development from Birch Street, loops back and ties into Street B. Street B is proposed to extend from Birch Street to the easterly property line of the ' 2 a i *'�5,�`D Ys'n�� -t ` +V'i f :; i ? s CO s! r' Mer CtNc re_ M► Nt-TFAC t 1, Stoneybrook Page 3 development to provide a connection for future development to the east. There are five proposed cul-de -sacs which intersect with either Street A or Street B. While staff recommends providing a street stub to the eastern property line for future street extension, the developer should demonstrate how the street would service the adjacent parcel. There is a large wetland complex east of the proposed street stub that would limit future alignment options. Additionally, the street abuts the St. Paul Water Utility property, which contains an existing large diameter water main. This may cause conflicts with the sanitary sewer and water main stubs as well as the roadway. The water k. utility is currently reviewing the proposal for possible impacts. Should the street be extended to the east property line, the applicant will be required to provide a permanent easement for a cul-de -sac to be constructed until the street is extended Signage should also be located at the street terminus indicating the future extension of the street. Street A is proposed as a large loop in the southern half of the development. While this section has two access points, they form the same intersection and create a situation similar to a long cul -de -sac. Staff has evaluated other alignment options, however it appears that these would cause additional wetland impacts. Staff is reviewing this issue with the Public Safety Department and the Centennial Lakes Fire Department to determine if there are any access concerns with the proposed layout. Staff is also recommending that the . applicant evaluate a possible street stub alignment to the south of the development in the approximate location of Street G. This would allow for a future connection with East Holly Drive. The 2001 Transportation Plan identifies East Holly Drive as a Minor Collector and proposes its future connection with Holly Drive to the west and Ash Street (County Road J) to the south. While these projects are not planned in the near term, it would be practical to reserve the option to connect this subdivision. to Holly Drive in the future.. Grading and Drainage. A grading plan has been submitted and is subject to the review and approval of the City Engineer. A Rice Creek Watershed District (RCWD) Land Development Permit is also required . The ..house .pad on Lot.. 9, Block 9 . should be . reoriented to provide a more suitable building pad. The plan does not identify the Normal or High Water Level for wetlands No. 12 and No. 13. Mitigation sites are proposed to be fenced off after grading is completed to restrict construction traffic. According to the plans, there are no provisions for bringing materials onto the site or hauling off the site. Utilities. A preliminary utility plan has been submitted and is subject to the review and approval of the City Engineer. Sanitary Sewer is proposed to be extended to the site from its existing location in Sherman Lake Road, north of Birch Street. Water will be provided by connection to the existing 16" trunk water main lying adjacent to the property on the south side of Birch Street. The water main is proposed to be looped back to the system by crossing Birch Street at Pheasant Hills Drive. Stoneybrook Page 4 Adequate capacity exists in the sanitary sewer system to service the proposed development. In addition, the Black Duck Lift Station, which services the area, is scheduled for replacement in 2003. Drainage and Utility Easements. Drainage and Utility easements are proposed being five feet in width at adjoining lot lines, and 10 feet in width at adjoining street lines and rear lot lines as required. Drainage and Utility easements covering the 100 year High Water Level and those covering underground storm sewers are subject to review and approval by the City Engineer. Easements should be provided to access all pond and wetland areas. Specifically, easements should be provided to access Outlot F and cover the emergency overflow on Lots 6, 9, and 10, Block 8. Parkland Dedication. The Park Board discussed the proposed subdivision at its February 4, 2002 meeting. The board is recommending 100% cash payment in lieu of parkland dedication. As explained in the Public Services Director's February 5, 2002 memo (attached), the proposed development lies outside the planning limits of the Comprehensive Park and Trail System Plan. The Park Board looked at several alternatives and recommended the payment in lieu as the preferred option. Floodplain. Portions of the site lie within a Flood Plain Zone A. Zone A represents areas of 100 year flood where base flood elevations have not been determined. The City's Floodplain Management Ordinance requires that principal structures be located no lower than one foot above the regulatory flood protection elevation. The City's Subdivision Ordinance requires that proposed basements be four (4) feet above the water table (normal water level) and two (2) feet above the design flood levels of ponding areas. The submitted grading plan identifies proposed 100 year High Water Level elevations. Conformance to the requirements cannot be determined for Lots 23 through 27, Block 8 due to lack of documentation on the normal and high water levels of wetlands No. 12 and No. 13. The applicant should submit this documentation. All other lots are in conformance. The proposal is subject to the review and approval of the City Engineer and Rice Creek Watershed District. If the proposed subdivision is approved, the Developer will be required to make application to FEMA for a Letter of Map Amendment (LOMA) or Letter of Map Revision (LOMR) to revise the existing Flood Plain maps consistent with the proposed grading. Wetlands. The project site contains 19.39 acres of wetland. 2.06 acres of wetland are proposed to be impacted by the site development. The wetland mitigation will take place on -site, by creating two new wetlands and three water quality ponds, which will have a total area of 2.51 acres and 3.27 acres, respectively. A portion (.20 acres) -of one of the existing wetland areas will be converted from a Type 2 wet meadow to a Type 3 s allow marsh wetland to help facilitate site drainage. Stoneybrook Page 5 The developer is proposing to install signs demarcating the wetland edge at property corners or where the wetland edge changes drastically within a lot. Approximately 35 to 40 signs will be installed (1 sign per two homes) along the wetland edge. The signs will designate the area as a protected wetland zone. The sign will also inform homeowners that moving or cutting beyond the sign is not allowed. The plans also delineate a wetland buffer easement adjacent to wetland to provide additional transition from cultured lawns to native vegetation. The application also includes a Monitoring Plan that provides for monitoring of the newly created wetlands for a 5- year period. The report will be submitted to Rice Creek Watershed District (RCWD) on a yearly basis. The RCWD is the Regulatory Government Unit (RGU) for administration of the Wetland Conservation Act. Security should be required within the development agreement to insure installation of signs as well as the required monitoring. This requirement will need to be coordinated with the RCWD. All exposed soils above the Normal Water Level should be seeded with mixes consistent with City of Lino Lakes seed mixtures. The applicant should coordinate seed types with the City's Environmental Specialist. Tree Preservation. The site contains a number of Oaks in the extreme southeast corner of the proposed development and one on the north side adjacent to Birch Street. The is no anticipated tree loss as part of this project. Although a fence area is shown around the tree on the site, a more detailed description of tree preservation should be submitted. Fences must be placed at a distance from the trees equal to one -foot radius for each inch of tree trunk diameter measured at 4.5 feet above the ground. The developer should coordinate all tree preservation activities with the City's Environmental Specialist. CEPTED. Officer Mike Rumpsa prepared a review on January 21, 2002 (attached). He expressed concern with the additional traffic load on Birch Street, particularly with morning rush hour traffic. Landscaping. A landscaping plan for screening along Birch Street has been submitted as required. The plan consists of a combination of Deciduous and Coniferous trees. The City's Environmental Specialist is recommending replacement of the proposed Colorado Spruce with the White Spruce. Environmental Board. The City's Environmental Board reviewed the request on March 27, 2002, and recommended denial of the request siting the need to submit plans to the St. Paul Regional Water Utility and the Vadnais Lakes Watershed District. They also submitted recommendation to consider if the proposal is approved. Their comments are attached and, were applicable, have been incorporated into this report. Rice Creek Watershed District (RCWD). The developer has made application to the RCWD for approval of a Land Development Plan and a Wetland Alteration Plan. The Stoneybrook Page 6 application is scheduled for review by the district on April 24, 2002. It is City policy to withhold any development approvals until the RCWD has approved, at a minimum, a TWAFAA (Tabled with Authorization for Administrative Action). Anoka County. The County is preparing comments with regard to the proposed subdivision and impact on Birch Street. It is staff's understanding that improvements to Birch Street, adjacent to the project site, may be required by the County. RECOMMENDATION T '''� ���` -� $ a 1-04-5 5 D The current status of the City's 2001 Comprehensive Plan and the associated MUSA allocation prevents the City from moving forward with this application. In addition, there are several preliminary plat issues that need to be resolved including the review by Rice Creek Watershed District. Staff recommends tabling the action on the MUSA Allocation, Rezoning, and Preliminary Plat requests to obtain the additional information and modifications contained within this report. ATTACHMENTS 1.

Peltier Lake Survey Information W h.en hundreds of great blue herons vanished from Anoka County, local residents rushed to respond From a vantage point across from Lake Peltier, Art Hawkins bas observed great blue herons for the past three years. On the cover. A great blue heron wades near the island on Lake Peltier. 9 Abandoned Nests: Why Are Great Blue Herons Disappearing from the Northern Metro? by Jennifer Amie Each year around St. Patrick's Day, the great blue herons return to the Rice Crer' chain of lakes, where they have nested since 1945.Their rookery on Lake Peltier island, on the border between Lino Lakes and Centerville in Anoka County, is home to some 200 of the large, majestic birds. he island's maple basswood forest provides the tall trees necessary to support the herons' nests, built from shaggy snarls of twigs and nestled in branches as high as 60 feet off the ground. In spring, the herons work to repair their nests, flying across the lake to gather sticks from nearby fields. In late March or early April, the female birds begin to lay their eggs, which they will tend over the following months. Typically, the herons remain in or around the colony through- out the summer as they raise their young. In mid- September or early October, they begin their southward migration. In March 2000, retired U.S. Fish and Wildlife Service biologist Art Hawkins was preparing for his second season observing the Lake Peltier herons on behalf of the Minnesota Department of Natural Resources (DNR). He set up his spotting scope in a farmer's field across from the lake, watching the birds fly back and forth across the water to fetch twigs and hunt for food. By May, the colony was well- established in what appeared to be a typi- cal nesting season. Then suddenly, in early June, the rookery went silent. Jeff Perry, a natural resources specialist for Anoka County Parks, was among the first to investigate. "We went out to the island in June 2000 and the rookery was quiet. There weren't any noises. It was a forest without any life in it," he recalls. The adult herons had vanished. On the ground beneath their nests, Perry found eggshells that appeared to have hatched, along with the bodies of juvenile birds that had died of starvation. "Everybody was shocked," Perry says. "Quite honestly, we were baffled." What would cause an entire colony of birds to abandon their eggs and hatch - lings? "Whatever it was, it was a massive disturbance," says Hawkins. "Birds are notoriously faithful to their nests during the late stages of incubation or with young to feed, conditions that prevailed when the mass desertion took place." A great blue heron catches a fish on the Rice Creek chain of lakes, where herons have nested since 1945. For the past two years, the heron colony at Lake Peltier has abandoned its rookery prematurely, and its hatchlings did not survive. New ordinances in Lino Lakes and Centerville aim to protect the herons, which have returned to nest again this year. Although such a mass abandonment during the height of nesting season is unprecedented, the summer of 2000 was not the first time the heron colony had been displaced from the Rice Creek chain of lakes —and it would not be the last. As many as 400 herons returned to nest at Lake Peltier in the spring of 2001 —but in June they once again abandoned the rook- ery. "A bird catastrophe of this magnitude is hard to assess," says Hawkins. Many unanswered questions remain. For two seasons now, the colony has produced no surviving young, and no one knows what the ultimate effect of these losses might be. Nor does anyone know where the herons went after they left the rookery, or whether they might one day decide to abandon Lake Peltier for good. In many ways, the forested island on Lake Peltier may represent a last stand for the herons that have endured both natural disasters and human expansion into their habitat. For two seasons now, the colony has produced no surviving young, and no one knows what the ulti- mate effect of these losses might be. Great blue herons first began to inhab- it Lake Peltier in small numbers in 1989. Today's colony, which has declined in pop- ulation to about 200 birds, is believed to have assembled from the remnants of two earlier colonies that were displaced from nearby lakes. Beginning in 1945, a colony of hun- dreds of herons nested on Rice Lake, south of Lake Peltier. These birds were displaced in the early 1990s by residential develop- ment and the opening of a nearby golf course, according to Joan Galli, a nongame wildlife specialist with the Minnesota DNR. A second heron colony inhabited Howard Lake, north of Lake Peltier, and once numbered 550 nests. The Howard Lake colony suffered severe losses during a wind storm in 1987 that downed nest trees and killed many young birds. The colony never recovered from the storm's devasta- tion and relocated to Lake Peltier. "The herons have retreated — literally and figuratively —to islands of habitat that are remote from human disturbance," says Galli. "They're very precariously situated. There isn't any lakeshore they can go to, because it's all developed. Their options are more and more limited as we expand our residential occupancy of this world." Today, the Lake Peltier heron rookery is one of only nine in the seven -county metropolitan area and is the second largest. Its birds fly up to 20 miles away to feed in ponds and marshes and along lake shores. "All the herons and egrets that citi- caurimmd ru? p.4 continued from p.3 zens see in their backyards in Anoka and Washington counties are most likely nest- ing in this one colony," notes Galli. In other words, the area's herons have all their eggs in one basket: Lake Peltier island, a 30 -acre oasis in a community that is rapidly shifting from agriculture to sub- urban housing development. Owned by Anoka County Parks, the island preserve is home to much more than the heron rookery. Forested with ash, bass- wood, elm, maple, and hickory, it provides habitat for deer and foxes as well as numerous birds —great egrets, wood thrush and veery, red -eyed and yellow - throated vireos, and scarlet tanagers, to name a few. The shoreline and shallows north of the island serve as a spawning area for Northern pike and walleye and as a resting area for terns, black crown night herons, and other waterfowl. The north arm of the lake, says Galli, is one of the few remaining places in the metro area with healthy native vegetation, including water willow, which is considered a species of special concern. Ringed by swiftly growing suburbs, the once- secluded lake now faces increasing pressures from nearby residential develop- ment and recreational use. "This is an area with lots of lakes, wet- lands, and wildlife," says Marty Asleson, environmental coordinator for the city of Lino Lakes. "Folks who are moving in want to preserve it, and that's tough .to do. Sustainability requires a balance between cultural and environmental issues." The heron colony is widely considered one of the county's most outstanding natu- ral features. In fact, the city of Lino Lakes adopted the great blue heron as its logo and even named an elementary school after the birds. Since the colony's abandonment last summer, local residents, city and county officials, and wildlife experts have worked diligently to solve the mystery of the birds' disappearance. With the help of Bell Museum director Scott Lanyon, an ornithologist and resi- dent of Lino Lakes, 10 potential causes of the birds' abandonment were identified in January 2002. Upon further examination, nine of these factors were ruled out, lead- ing a local task force to focus on the most likely possibility: disturbance caused by human activity near the rookery. A heated debate emerged over the Today, the Lake Peltier heron rookery is one of only nine in the seven - county metropolitan area and is the second largest. Great egrets also nest at Lake Peltier. potential impact of a slalom waterski course that had been installed by local resi- dents in the shallow waters along the north side of the island. Though no one can prove that water - skiing is the direct cause of the colony's abandonment, many believe that the extreme disruption and repetitive nature of slalom waterski racing could have been sufficient to drive the birds from their • nests. "We received many comments from residents about high speed boat traffic so that was one of our primary considera- tions," says Perry. Great blue herons are wary, skittish birds. Studies show that, like many birds that nest in colonies, they are particularly vulnerable to human disturbance and rec- ommend a protected "buffer zone" of 250- 500 meters around nesting areas. Though enacting changes meant a complex collaboration across two jurisdic- tions, the city councils of Lino Lakes and Centerville moved quickly to protect the birds. The councils voted to relocate waterskiers to the southern portion of the lake. To protect the rookery and the sensi- tive ecological zone on the north end of the lake, they passed joint ordinances cre- ating a no -wake zone starting approxi- mately 250 feet south of the island. The north end remains open to fishing, canoe- ing, and slow -speed boating. It is hoped that this new buffer zone will protect the rookery from disruption and allow the herons to complete their nesting season. The new ordinances will take effect this summer and will remain in place through 2004. Although some residents opposed the no -wake zone, Galli says it was a neces- sary measure. "We don't think we can wait any longer," she says. "We need to take action now if there's anything we can do that might have meaningful conse- quences." In addition, DNR and park staff mem- bers are working to minimize other traffic in and around Lake Peltier, including sea planes, mosquito control helicopters, and firefighting planes that collect water from the lake. The successful coordination among the several jurisdictions responsible for Lake Peltier —and the swift action of two neigh- boring city councils —may serve as a model for the many other suburbs attempting to conserve natural areas in the face of increasing human activity. As more and more people want to liv closer to nature, many communities are forced to address the impact of increased residential development on their lakes, wetlands, and woodlands. The conflict between boats and birds in Lake Peltier is a classic example of a cultural and envi- ronmental clash, says Marty Asleson, who believes that the new ordinances will be an effective compromise. In March of this year, Art Hawkins returned for a third season to the shores of Lake Peltier, toting a spotting scope and notebook and hoping to see the first arrivals in the herons' spring migration. As cormorants stood guard on the bog poles nearby, Hawkins has watched as great blue herons have once again flown back and forth across the water, fetching sticks for the nests they have abandoned for the pre- vious two years. Now it is the beginning of May and so far, says Hawkins, everything seems to be going well. ■ To find out whether the new ordinances succeed in helping the Lake Peltier heron complete their nesting season, look for a >. update in the fall issue of IMPRINT. • -Nuirmilu- Marty Asleson Page 1 of 2 From: Paul Nelson Sent: Friday, June 14, 2002 10:25 AM To: Steve.Kittelson @dnr.state.mn.us Subject: Subject: Re: Blanding's turtle Hello Steve, My turtle sighting was on County Road J, just west of the first house that is about 200 yards west of the Shadow Ridge Driving Range. The Driving range is about a half mile west of Centerville Road. There is a large swamp / wetlands the borders the north side of the driving range and that first house property. I saw it at about 7:30 Sunday 6/9. It was on the shoulder, facing starting to cross the road going south towards North Oaks, obviously an upscale turtle. I help a lot of turtles across the road. When I first saw it as I was driving, I thought it was a snapper because of the size. As I pulled over I noticed the bright yellow throat. This turtle had a brown smooth shell like a painted turtle, but was as big in diameter as football, much larger than any painted turtle I've ever seen. It shell was at least twice as thick from belly to top and more elongated than a painted turtle shell. Paul K. Nelson Regional Sales Manager The Specialty Mfg.

Stems entirely under water; usually much - branched, and sometimes stiff with a coating of lime. At each joint is a whorl of leaves. Leaflets vary in length, width, firmness, amount of forking, and prominence of teeth. Flowers and seeds, at base of leaves, are usually hard to find. The commonest form of seed is pictured. Other forms have as many as a dozen spines. 55 Najas flexilis, half life -size two times life -size Najas gracillima, half life -size • two times life -size 64 NAIADS, Najas (except SPINY NAIAD, page 67) Fresh inland water and fresh to slightly brackish coastal water; British Colum- bia to Newfoundland, Califor- nia, and Florida. Six kinds resemble each other so much that they can be told apart only by using a hand lens or microscope to look at the toothing of leaf edges, the shape and toothing of leaf bases, and the mark- ings on seeds. Tops of plants are often almost out of sight under water. Plants vary in size from tufts an inch high on sandy bottom to much - branched plants two or three feet high on silty bottom. The six kinds are: Najas conferta. Not pic- tured. Southwestern Georgia and western Florida. Leaves usually curve out from the stem, and their marginal teeth are visible to the naked eye. Resembles minor (page 65); but the seeds are not ribbed lengthwise. Najas flexilis. British Columbia to Newfoundland, Cali- fornia, Missouri, and Virginia. Leaves usually curve out from the stem. Unlike the other kinds, its seeds are shiny under the dull, easily-rubbed- off skin. Najas gracillima. Minne- sota to Maine, Missouri, and North Carolina. Threadlike leaves usually curve out from the stem. Resembles flexilis; but usually has slenderer • • leaves and has wide - topped leaf bases and dull seeds. Najas graminea. Not pictured. A native of the Old World which has run wild in California ricefields. Very bushy with leaves which usually curve out from the stem. Resembles flexilis (page 64); but has dull seeds. Najas guadalupen- sis (Najas muenscheri and olivacea). Oregon to Quebec, California, and Florida. Leaves are shorter than in the other kinds, usu- ally do not curve out- ward, and are not much bunched. When without seeds, guadalupensis resembles underwater forms of Water -star- wort (page 61); but the leaves have sheathing bases. Najas minor. Illinois to Vermont, Alabama, and Florida. A native of Eurasia which in the last forty years has be- come common in the tidal Hudson River and in artificial lakes. Leaves usually curve outward, and their marginal teeth are visible to the naked eye. Unlike the other kinds, its seeds are ribbed lengthwise. Najas guadalupensis, half life -size two times life -size Najas minor, half life -size 65 two times life -size • COMMON ELODEA, Elodea canadensis (Elodea nuttallii; Philotria canadensis and linearis) Fresh to slightly alkali inland water and fresh to slightly brackish coastal water; British Columbia to Quebec, California, and Florida. Leaves vary greatly in width, size, and bunching; therefore plants are often slimmer or stouter than as pictured. Sometimes there are slim seed pods at the base of leaves. Big plants resemble small plants of South American Elodea (page 68); but toward the tip of stems the leaves of Common are in twos or threes at a joint, those of South American are in fours or fives. Plants with narrow, limp leaves re- semble underwater forms of Water - starworts (page 61); but Elodea leaves are bunched toward the tip of stems and usually are in threes at a joint.

When not in bloom or seed, resembles non - seeding Widgeongrass (page 73); but the leaves are usually in bushier clusters, the sheathing base of the leaves has a tapering, flimsy tip, and the rootstocks are long and straight and often have tubers. half life -size FLATSTEM PONDWEED, Potamogeton zosteriformis Fresh water, inland and rarely coastal; Alaska to Quebec, Cali- fornia, Nebraska, and Virginia. Stems several times as wide as thick. When not in bloom, resembles non - blooming Water- stargrass (page 79); but has leaves with prominent midvein and non- sheathing base. \\1\\/ half life -size two times life -size 76 RIBBONLEAF PONDWEED, Potamogeton epihydrus Fresh water, inland, particularly in slow streams, and rarely coastal; Alaska to Quebec, California, Colo- rado, and Georgia. The very limp underwater leaves have a light - colored center stripe. Usually there are floating leaves. half life -size two times life -size CURLY PONDWEED, Potamogeton crispus Fresh inland water and fresh to slightly brackish coastal water; Alberta to Quebec, California, and Florida.
