Variance to the local street setback to allow for a covered porch addition at 8020 Danube Street, James Schally Mr. Bengtson presented the staff report. DRAFT MINUTES Planning & Zoning Board May 9, 2007 Page 2 Staff recommended approval of the variance request. The applicant, Mr. James Schally, was not present at the meeting. Board Members discussed the necessity of the roof and the intent of the porch. Mr. Pogalz made a MOTION to recommend approval of the Variance to the local street setback to allow for a covered porch addition at 8020 Danube Street. Motion was supported by Mr. Laden. Motion carried 6 - 0. B. CONTINUED PUBLIC HEARING for a Conditional Use Permit for earth material storage at 6644 20th Avenue, Royal Oaks Realty Mr. Studenski presented the staff report. Mr. Studenski stated that resident Julie McNeely, 6687 20th Ave., was unable to attend the meeting but asked staff to forward her comment to the board that she is against the proj ect. Staff stated their review was based on the 14 conditions of the Zoning Ordinance for Earth Moving and Land Reclamation. Staff reminded the board of the petitions against the project that were submitted at the April meeting. Mr. Studenski explained that the city had received a review from the Anoka County Highway Department earlier that day. He clarified that neither the county nor the city would require the additional 27 feet of right -of -way for this request. He stated that County comments included: moving the driveway as far to the north as possible, adding a culvert, and constructing north and south bound turn lanes and a bypass lane. The City contacted Anoka County after receiving the letter, and was informed by Randy Bettinger at Anoka County that road improvements will be required regardless of the number of trucks per day, but the required combination of lanes still needs to be determined. Mr. Studenski added that drainage calculations would be required to determine how drainage would affect the county road and that a Haul Permit is required by the county. Mr. Studenski explained that the deadline for this application is June 6, which requires action by the P &Z Board at this meeting. He added that the applicant did not see a rationale to extend the item. Mr. Studenski noted that the Rice Creek Watershed District does not require a permit, but will monitor the site. Mr. Studenski stated that the applicant had already addressed a number of issues and conditions since the previous meeting. Staff explained that the dirt pile had been moved to a location more than 50 feet away from any existing trees. The applicant submitted a Storm Water Pollution Prevention Plan (SWPPP), filled the house foundation, abandoned the septic system, cleared and removed debris and objects from the site, added a fenced barricade to the driveway entrance, and added a dirt berm to the northern access. Staff recommended approval of the Conditional Use Permit subject to the 13 conditions listed in the staff report. DRAFT MINUTES • • • • Planning & Zoning Board May 9, 2007 Page 3 Mr. Nelson referred to Condition No. 12, and asked what would happen if the county decided to allow a variance that the city did not agree with. Staff replied that the county will have their own requirements. Mr. Studenski stated that the city could amend the conditions of approval to address this. Staff confirmed that the existing stockpile is currently 22 - 24 feet high. Mr. Pogalz asked why the trips per day were reduced from 50 to 25 trips per day. Staff said they had reduced the number in response to resident and Planning and Zoning Board Member concerns. Mr. Laden pointed out that the ordinance requires that an applicant specify a completion date, and asked if a completion date had been addressed. Mr. Studenski replied that development is anticipated on the site in the near future and, due to the limited amount of activity that will occur, staff had not requested a specific completion date. Staff noted that the board could recommend a deadline date, but that all CUPs are reviewed annually. Applicant, Mike Black, Royal Oaks Realty, 1000 County Road E, Suite 150, Shoreview, MN, reiterated that the zoning ordinance allows this use in any zoning district. He stated that conditions are required for a CUP in order to make the use compatible with neighboring properties. Mr. Black described that Royal Oaks Realty is a land development company, Royal Excavating is their sister company, and Imperial Homes is the home building company and they all work together. He explained the intent of their request is to stockpile dirt for their own company and that dirt will not be sold to other companies. He said they presume that some weeks there may be no trucks accessing the site, and explained that they will access the stockpile when there is final grade work being done. He noted that they never intended to be hauling material in and out on a daily basis, and only when there is a bigger job would they possibly meet the maximum trips per day. He thanked the board members that were able to visit the site. He stated that they have tried to meet a number of staff's recommendations since the last P &Z meeting, and they should not have a problem adhering to staff's conditions of approval. He stated that he spoke with Randy Bettinger of Anoka County earlier that day regarding the county review. He was told by Mr. Bettinger that the County is offering comments, but not necessarily requirements. He said Mr. Bettinger stated that the county does not require the road improvements. Mr. Black spoke of the possibility of moving the entrance. He said he is concerned about the road recommendations, but added that Mr. Bettinger told him that if the city does not require this, then the county does not require it. He would like an opportunity to discuss the county's recommendations with city staff and the county. Mr. Nelson commented that he believes that the term grading means a one -time earth moving. Mr. Laden believes the intent of the ordinance is for a temporary use, and that a final grading plan and a project completion date are required. Mr. Black stated that the property is guided for medium density residential and that they hope to develop in two to five years or sooner. He explained that once there is a DRAFT MINUTES Planning & Zoning Board May 9, 2007 Page 4 development application, the use will stop. He added that they would not go through with the application if the county required the turn lane changes. Mr. Laden said he believes that to allow storage means something will be stored and will stay there. Mr. Black informed the board that the majority of the dirt came from Centerville and that only black dirt will be stored on the site. Mr. Rafferty asked Mr. Black to consider how he would feel if he were a neighbor. Mr. Black reminded the board that this would be a conditional use in which staff can apply conditions in order for the property owner to use the property in a certain way. Mr. Black reiterated that dump trucks will not be accessing the site every day and he feels a cap of 25 trips per day is feasible. He estimated, on average, possibly 10 trips per day once a week would access the site. Mr. Nelson suggested limiting the number of trips per day to a monthly threshold instead of a daily threshold. Chair Tralle opened the Public Hearing at 7:27 p.m. Mrs. Patrice Carpenter, 6748 20th Ave., said she stated concerns at the last meeting. She said the applicant has been a good neighbor and has been making a lot of improvements. Her concern is that he didn't get permission prior to the stockpile placement and movement. She is concerned about the issue of the turning lanes and that moving the driveway north would be a lot closer to her. She said there is a blind hill heading north on 20th, so if they moved the driveway to the north then turn lanes would be necessary. She stated there is no need for turn lanes if the driveway stays in its current location. She understands the site is rural and she is used to dirt, but doesn't know when the dirt will be flying around. She feels there is no way to vegetate anything with all of the earth movement. She does not feel the height of the dirt pile makes a difference. She informed the board that flying dirt is a nuisance. She was relieved to hear the dirt came from Centerville. She said she would really not like the use here and would have liked it more if the applicant had asked permission prior to them doing it. Mrs. Carpenter recommended that the board not approve the request and asked that the pile of dirt be moved. John Pignato, 6709 20th Ave. S., stated that there are no turn lanes in Centerville, and that all kinds of traffic is going there now, just not so many dump trucks. He said they have been putting up with semi - trucks and earth moving equipment for a long time because of new businesses in Centerville, noting this is just another straw in the camel's back. He feels that they will be accessing the site more often than Mr. Black has suggested. He stated that dirt is blowing and there is mud on the road. He stated that he is against the application and hopes the board denies it. Mr. Tralle asked Mr. Black to address some of the concerns. DRAFT MINUTES • • • • Planning & Zoning Board May 9, 2007 Page 5 Mr. Black said that they will Hydro -seed the stockpile to establish vegetation and reseed as necessary. He added that they have a truck for watering and they will sweep as needed to clean and maintain the road. He said they do not have a problem with a gravel driveway as it is almost there by now. He anticipates they will be moving the dirt small sections at a time. He is willing to create a new driveway to within 30 feet of the property line if it is required. He added, however, that trees there currently act as a buffer, so if the drive is relocated north of the trees the buffer will be lost. Mr. Nelson suggested the possibility of adding a stipulation for use at three to four years and capping the allowable trips per month. Mr. Black said that sounded reasonable, but was not sure if the attorney would agree with adding a completion date. Mr. Black said he understands they are trying to find thresholds of compatibility. He reiterated that the use is not intended, and was never intended, to be a constant moving activity, but simply supplemental material available for nearby construction sites as need be. He asked the board to consider a one year allowance to prove that it will be a compatible use with the neighborhood. Mr. Pogalz made a MOTION to close the Public Hearing at 7:47 p.m. Motion was supported by Mr. Hyden. Motion carried 6 - 0. Mr. Pogalz reiterated his comments from the last board meeting. He stated that the property is zoned rural, which allows more flexibility to the property owner. He added that it could be a lot worse if the property was used for farming. He pointed out the this sounded like an example of NIMBY — Not In My Back Yard, which means that residents are okay with things as long as it's not in their back yard. He added that turn lanes sound okay because the county may require them with development. He suggested they look at this use as a distribution center somewhat like Schwan's. He feels they are putting good limits on a use. He noted that normal construction operations happen as areas develop. He added that the use would go away in a few years as the land would be more valuable with homes rather than dirt on it. He stated he is in favor of approving the CUP. Mr. Rafferty made a MOTION to recommend denial of the Conditional Use Permit for earth material storage at 6644 20th Avenue. Motion was supported by Mr. Laden. The following role call vote was taken, Nelson: No, Root: Yes, Rafferty: Yes, Hyden: No, Pogalz: No, Laden: Yes, Tralle: Yes. Motion carried 4 -3. Mr. Studenski asked for the board's rationale for denial, which he stated is necessary when an application is forwarded with a recommendation for denial. Mr. Root stated the use is too intense for the roads and a nuisance for the neighbors. Mr. Rafferty believes this use is not what the ordinance intended. Mr. Tralle does not agree that there is no end in site, he is disturbed that they did not ask permission prior to use, and he does not feel they can monitor the amount of traffic. Mr. Laden stated it does not meet ordinance requirements without an end date. He considers it to be an off -site delivery business that would not be allowed in a rural zone. DRAFT MINUTES Planning & Zoning Board May 9, 2007 Page 6 Mr. Nelson suggested putting a new motion on the table to include a completion date for the use. Mr. Tralle stated that a motion had already been passed for the application. The board took a 10- minute recess at 7:57 p.m. The meeting reconvened at 8:08 p.m. C. PUBLIC HEARING for a Conditional Use Permit for earth material excavation and storage at 6497 12th Avenue, A.I.T. Mr. Studenski presented the staff report. He added that Anoka County does not require any permits for activity from this site as the site does not directly access onto a county road. He stated the deadline for this application is June 7, so the City Council would have to take action at the May 19 meeting. Therefore, the board would have to take action at this meeting to meet the time frame. Mr. Studenski described the site layout per the exhibits included in the staff report. He noted that they will only access the westernmost pile across the ditch if it becomes necessary to obtain the required amount of fill. Mr. Studenski said that the Rice Creek Watershed District (RCWD) has not taken action on the project at this time. He said the applicant does not intend to move any trees on either site. He explained that the activity going in and out of The Preserve site will be intense at some time regardless of where the dirt comes from. He added that this is possibly the shortest truck route possible to the site. Mr. Studenski reviewed the conditions of approval that staff suggested for this application. He added that Condition 15 will be changed to read that no permits are required by Anoka County. Mr. Studenski stated that the ponds will be monitored to discharge water prior to reaching the ditch. He does not anticipate issues and added that the city and RCWD will monitor the flow. Mr. Studenski said that pumps will run continually in order to work effectively. Board members discussed the possibility of using flags and limiting the speed of trucks in order to help with traffic flow. Staff stated that traffic activity on Birch St. will be monitored and that flagging will be required if determined to be necessary for safety. Board members discussed the proposed ponding areas, including slopes, pond depths and vegetation. Mr. Studenskin explained that the applicant will vegetate according to city specifications. He said that one pond will be very shallow and the one to the west of the house will be 18 -20 feet below the water table. He noted that the smallest pond is the least desirable and most expensive to excavate, therefore the specific process of excavation will be determined by the contractor. DRAFT MINUTES • • • • • • Planning & Zoning Board May 9, 2007 Page 7 Board members wondered why the ponds did not include a bench for safety reasons. Mr. Studenski explained that the applicant is not creating any water storage areas and the ponds will not be designed to be long -term. Mr. Studenski informed the board that caution signs are typical with development, and signs will be placed along Birch St. so it is not necessary to include this as a condition. Applicant, Mr. Brian Bourassa, MFRA Engineering, Plymouth, MN, and Adam Parker, hydrologist, answered questions for the board. Mr. Bourassa stated that berms around the dewatering equipment would be a great idea. He explained that the material they are going after is sandy material for building roads and house pads, and they will need an estimated 50,000 to 60,000 cubic yards for The Preserve site. Mr. Bourassa said he lives in the area and is aware that traffic is difficult. He likes the idea of warning signs on Birch St. and 12th Ave, and is open to staff's recommendations regarding flagging. Mr. Bourassa showed the board members the location of the temporary storage on the site. He noted that the Environmental Board had suggested a specific seed mix for vegetation, and he will work with Marty Asleson at the City. He said he didn't show a bench because there is no development plan there, but realizes at some time a bench will probably be required. He noted that the water level in the ponds is estimated to remain what it is today. He said they do not anticipate accessing the third excavation site. He described that if they use six to eight 12 -yard trucks to haul the estimated 50,000 cubic yards of dirt during haul hours, it would take 13 days if everything ran perfectly. Realistically, they estimate it will take four to six weeks to haul the dirt for The Preserve. Mr. Parker explained to the board the dewatering process that will be used on the site. He explained that a number of engineers on staff will help determine the best vegetation and will follow the city's recommendations. He explained that SWPPPs will limit dust and keep topsoil in place. Board members expressed concern about water levels, safety of the excavation site and street clean-up and maintenance. Mr. Parker remarked that the vegetation used will be selected to handle the water levels, with only three to four foot fluctuations expected. Mr. Bourassa added that there will be no discharge from these basins and expects there to be less water or the same as there is today. Mr. Bourassa stated that silt or snow fencing will be used for safety. He explained that they are proposing a rock trench entrance to knock dirt off the wheels, a silt fence to prevent erosion from the pile, and will comply with requirements regarding street sweeping. Mr. Pogalz pointed out that the application is for an expected use of 90,000 cubic yards, with 50,000 going to The Preserve. He asked if the excess material will be sold to another developer or development and why they should allow him to take the material off site. He asked why they couldn't just take the 50,000 to 60,000 for The Preserve. Mr. Bourassa replied that the purpose is to haul the excess material to a different site. DRAFT MINUTES Planning & Zoning Board May 9, 2007 Page 8 Mr. Bourassa suggested the board could but a sunset period on when the site needs to be cleaned up. He went on to say if there is a market for the material, and they think there is, they propose to sell it. Mr. Pogalz pointed out that a timeline of four to six weeks is expected for The Preserve, with an extra four to six weeks to access additional sites. Mr. Bourassa clarified that additional trucks may be used for the other sites. Mr. Tralle stated that if they are going to have to put in a bench eventually, then it should just go in now. He asked what the restoration plan is for the area. Mr. Bourassa replied that the property owners, the Lamottes, see the ponds as a buffer to the future growth area. Mr. Tralle asked what the estimated truck traffic would be on a normal day. Mr. Bourassa replied that they expected six to eight trucks to haul all day long for roughly four to five weeks. Mr. Tralle opened the Public Hearing 9:06 p.m. Bill Combs, 6496 N. Trappers Crossing, said his property is on the comer lot directly behind the large stockpile site. He was concerned about safety issues. He said he has young boys and a dog that play on the Lamotte property and he is not convinced of safety with the proposed silt and storm fencing. He was concerned about how close to his property line the pond would be and how big it would get. He was concerned for the safety of his children and other children. Mr. Bourassa responded that the start of the grade is maybe 10 -15 feet north of property line. He anticipated water elevation to be maybe 120 feet north of his back property line. Joe Knudsen, 6525 White Oak Rd., stated concerns about trucks exiting on 12th Ave. and asked how close to the road the proposed stockpile would be. He was concerned it would be near development. Mr. Bourassa explained that the temporary stockpile of sand and dirt would be stored north of the trees and west of 12th Ave. Mr. Knudsen also expressed concern about the number of trucks and truckloads that would be used. Mr. Pogalz estimated that in a ten -hour day, approximately 240 truckloads could be hauled per day for 28 days. Mr. Knudsen stated concern for damage that may be done to the road. Mr. Studenski replied that they applicant would be required to replace any damage in kind with what is there now. Tim Renslow, 6586 Pheasant Run South, requested a confirmation of the proposed truck route. Mr. Bourassa explained the route to be used. Mr. Renslow added his concerns included dust, noise, and safety for children. He was very concerned that many of the families in the area have small children that may get hurt. Mr. Tralle replied that they are not disregarding the issues. DRAFT MINUTES • • • • • Planning & Zoning Board May 9, 2007 Page 9 Mr. Renslow added that he is concerned about the condition of Pheasant Run S. Mr. Tralle responded that they can reduce truck speed and the applicant will clean the roads on a daily basis. Mr. Pogalz explained that Pheasant Run S. will see just as much traffic regardless of where the dirt will come from as it has to come from somewhere. He added it is probably better that it come from a nearby site as it would happen faster. Ben Peterson, 6441 Royal Pines Place, stated his property is directly south of the southern property line. Mr. Peterson requested that they put the snow fence around the entire property. He asked how many backhoes and diggers would be used and if they would be using bobcats. He wondered how many water pumps would be used. He wondered once they start digging dirt out of the ponds, how long will it take to dry until it can be hauled away. He asked how lon the project would actually last. He stated he has concerns about traffic, especially on 12 Ave. He noted that the property owner has planted great trees on the property and wondered if he could line the southern property line with trees, adding that he would be willing to help out if needed. Mr. Bourassa believes the operation will consist of one backhoe and one dozer accessing one pond at a time. He does not anticipate the use of bobcats, but one front endloader may be used. He estimated that one pump at a time will be used for dewatering. He stated that they propose to place silt or snow fence around excavation areas as shown on the plan for safety measures. Mr. Tralle pointed out there is a wetland area between Mr. Peterson's house and the excavation area. Mr. Peterson added that an increase of trucks might add curiosity to kids and he is concerned about their safety. Shari Livingston, 6574 Pheasant Run South, and father Larry Stinksy, stated concerns about the amount of truck traffic on Pheasant Run S. He stated there is a park where the truck traffic will be going through. He is especially concerned about times when kids are coming home from school or accessing the park. He added that cars always parked on the street, making it a hazard. He distibuted photos to the board of standing water in the drainage ditch behind the house, adding that the photos were taken after one day of heavy rain. Rick Reibel, 6535 Pheasant Run South, was concerned about the safety of children. He doesn't believe the lanes are very wide on the road, and with community sports there are often kids on the street by the park and riding bikes. He pointed out that their neighborhood includes diverse neighbors that may have issues with understanding signs. He was concerned about the environmental impact of the surface water drainage system. He stated concern about high water levels on Black Duck Drive to the north. He would like to see an independent report of the environmental water impact table, stating that they should be able to provide numbers with a hydrologist on board. He is concerned about cranes and Canadian Geese that nest in the drain field each year. He has concerns DRAFT MINUTES Planning & Zoning Board May 9, 2007 Page 10 about drinking water, heavy loaders possibly degrading Pheasant Run, vibration, and if there are contingency plans for operating damages. Mr. Studenski stated that any activity adversely affecting neighbors is the responsibility of the applicant. He added that the city will monitor truck traffic, and if issues occur they will be addressed. Mr. Hyden reiterated that the RCWD is involved in monitoring this project. Mr. Parker addressed hydrology questions. He explained that the DNR is the authority and they will work closely with them. He said that runoff will go through other wetlands before reaching the ditch. Mr. Laden made a MOTION to close the Public Hearing at 9:38 p.m. Motion was supported by Mr. Nelson. Motion carried 6 — 0. Mr. Laden said he was concerned about the truck traffic being allowed next to a city park during hours when activities are occurring with children and on- street parking. That's where he sees greatest danger. He proposed limiting or eliminating truck traffic during evening hours. Board Members agreed to amend Condition No. 12 to read Monday — Friday 7 a.m. to 5 p.m. Mr. Rafferty said he is concerned about city streets but is not sure they can contain people from development that is already approved. Mr. Rafferty suggested adding a condition to reduce the speed of trucks to 20 mph. Board Members agreed to add Condition No. 18 to say that trucks will be limited to a maximum speed of 20 mph. Board Members agreed to add Condition No. 19 to say that the city will monitor traffic and define traffic signage to include the necessary use of flagmen and hauling signage at the contractor's expense. Mr. Studenski confirmed that neighbors would be notified of work to be done and that a neighborhood meeting would be held. After discussion about the silt/snow fencing, Mr. Bourassa agreed to use snow fence instead of silt fence, and to continue the fence southward until it reaches the wooded area. Mr. Pogalz specified that the board is considering a CUP for excavation, storage and transporting of material and asked if anyone could explain the difference between this application and the Royal Oaks Realty application that was previously denied. Mr. Studenski stated that both applications consist of on -site material being taken off site, and the differences include the site of destination, what is to be removed, the time frame and the restoration plan. Staff reminded the board that with this application, the use will not continue on indefinitely, they know that this will be a concentrated effort once activity is DRAFT MINUTES • • Planning & Zoning Board May 9, 2007 Page 11 • started, and they will not have random material coming in and out for an undetermined • time frame. Mr. Pogalz stressed that the same restrictions should be applied to this site as were proposed for the other site. He does not see enough of a difference in applications to vary the conditions for daily watering, erosion control, fencing, and vegetation within 24 hours. He asked board members for feedback. Mr. Tralle pointed out that this application is different because the applicant came before the board legitimately before starting activity, the dirt is being used in Lino Lakes, and the use has an end date. Mr. Studenski added that this is a concentrated effort in that when they are doing the excavation it will be continually hauled off the site. Mr. Tralle stated that the board will no longer speak of the Royal Oaks Realty request because that is a separate application that the board already took action on. Mr. Studenski clarified that there will be a time that the topsoil will be at the storage site, which will be part of the SWPPP. Board Members agreed to add Condition No. 20 to say that the stockpile area will be limited to a maximum height of 25 feet. Board Members agreed to add Condition No. 21 to say that areas that will not be worked on within 48 hours are required to be hydro- seeded. Mr. Nelson pointed out that 50,000 cubic yards of material will remain local, while 40,000 cubic yards will go offsite, which makes the use more like a distribution center with an excessive number of trucks. He was concerned that the hauling of the extra 50,000 cubic yards will go on for five to seven months in a residential area, while they were previously concerned about a rural area. Mr. Laden reiterated the biggest difference is this application has an end date. Board members pointed out the similarities between this application and the application that was previously denied under Item 5B, however the majority of board members agreed that enough differences were merited. Mr. Laden made a MOTION to recommend approval of the Conditional Use Permit for earth material excavation and storage at 6497 12th Avenue based on the following conditions of approval: 1. A Stormwater Pollution Prevention Plan (SWPPP) in accordance with Minnesota Pollution Control Agency (MPCA). The SWPPP must contain the name and a 24 -hour telephone number of the responsible manager of the SWPPP. All references to MNDOT seed mix must be changed to the City native seed mix. DRAFT MINUTES Planning & Zoning Board May 9, 2007 Page 12 2. Silt fence must be added around the excavation for safety reasons. 3. Properly fence and barricade entrances to prevent the general public from depositing garbage or refuse. 4. Must provide a tree preservation plan or limit excavation of material to a minimum of 50 feet from any trees. 4. All truck hauling activity must exit the site on 12th Avenue South and go north to Birch Street. 5. All City streets where hauling activity occurs will be video taped previous to excavation commencing at the site. The applicant will be responsible for repairing any damage to City streets caused by the hauling activity. 6. Previous to any activity on the site the applicant will be required to hold a neighborhood meeting to notify affected property owners along the haul route and within one - quarter of a mile of the site. 7. Maximum slope on any excavation shall be a 1 to 1 and in such condition as not to be dangerous because of sliding or caving side slopes. 8. Only topsoil will be allowed to be brought into the site. 9. A rock trench entrance shall be installed and maintained at all times. 10.

Respectfully submitted, Dawn Bugge Community Development Assistant DRAFT MINUTES • • • AGENDA ITEM 5.A. STAFF ORIGINATOR: Paul Bengtson P &Z MEETING DATE: July 11, 2007 TOPIC: Public Hearing: Grandview Preliminary Plat BACKGROUND Royal Oaks Realty has requested approval of an 8 lot residential subdivision to be known as Grandview. The subject site includes the outlot east of Gethsemane Church, and the parcel occupied by the parsonage house. The parsonage house lot and the previously granted roadway easement that would connect the Shores of Marshan Lake and Marshan Meadows subdivisions via Stage Coach Trail will both be slightly altered to allow the development of 8 total lots while still meeting all zoning ordinance requirements. The project was brought before the Planning and Zoning Board at the June 13th meeting, with some discussion and the public hearing opened and continued to the July 11th meeting. The only modification or correction that needs to be made is the question about the option of placing docks on Marshan Lake. ANALYSIS The following is a summary of the proposal: Site Area 3.76 acres Net Acreage 3.67 acres Total Lots 8 Gross Density 2.13 units /acre Net Density 2.18 units /acre Comprehensive Plan, Land Use and Zoning: The table below identifies the existing land use and zoning as well as guided land uses for the area. Location Existing Land Use Guided Land Use Existing Zoning Site Vacant Low Density Sewered Residential R -1 (Single Family Residential) North Residential Low Density Sewered Residential R -2 (Two Family Residential) South Residential Low Density Sewered Residential R -1 (Single Family Residential) East Marshan Lake N/A N/A West House of Worship Public / Semi - Public R -3 (Medium Density Residential) • Growth Management, MUSA Reserve: The subject site is currently located within the MUSA boundary area. • • Growth Management, Units/Year: The table attached to this report shows the status of the staging plans for final platting of new residential units. The seven new units of Grandview would fit within the policy of 147 per year and so could be final platted immediately. Preliminary Plat Shoreland Ordinance: The subject site is adjacent to Marshan Lake, which is considered a Natural Environment Lake and therefore is subject to the more restrictive Shoreland Ordinance Requirements for Lot Dimensions, Impervious Surface Coverage, and Setbacks as listed below: Lot Area Lot Width Impervious Surface Coverage Setback from OHWL Abutting Non - Abutting Abutting Non - Abutting 20000 10800 80 80 30% 150 feet Lots: The lots will vary in depth from 135 feet to 260 feet (along the shoreline), and the widths will range from 80 feet to 86 feet. The lots located along Marshan Lake exceed the shoreland ordinance required 20,000 square feet of upland, and the western lots all exceed the 10,800 square foot R -1 requirement. The parsonage lot will be reduced in size to allow the other three lots west of the proposed street to meet all subdivision standards. Setbacks: The submitted plans depict all required setbacks, including the 150 foot setback from the Ordinary High Water Line as required by the Shoreland Ordinance. This setback is measured to any improvement attached to the single family dwelling, including decks and/or patios. This means that the northeast lot (indicated as Lot 1, Block 2) will be very limited in that regard. Impervious Surface Coverage: The lots will all be required to comply with the 30% Impervious Surface Coverage requirement of the Shoreland Ordinance as they develop. Streets: Stage Coach Trail will extend from the southern border to the northern border connecting The Shores of Marshan Lake and Marshan Meadows. The alignment of the street is proposed to vary slightly from the current easement granted by the church. This was necessitated by the requirement to provide 20,000 square feet of upland for each lot along the shoreline and will allow a seamless connection with the existing rights of way on either side of the project. This proposal will require the approval of an easement vacation that will need to accompany the final plat to the City Council. • Conservation Easement: A Conservation Easement was supplied by the developer for Marshan Meadows and it is the city's intention to have this continued along the rest of Marshan Lake with any new development. Several rare species may exist in the area: Forsters' tern, a water nesting bird, and Blanding's turtle; which are on the threatened and endangered species lists. The conservation easement coincides with the drainage and utility easements required by the subdivision ordinance, both being 10 feet beyond the wetland edge. The conservation easement will include additional restrictions such as no mowing or dumping of clippings. There should also be a special packet of educational information supplied to homeowners and monuments at the easement boundary of all lake lots. At last months meeting it was stated by staff that the conservation easement would prohibit docks on the lake, which was incorrect. The documents do not specifically prohibit docks, but the likelihood of any docks being constructed is pretty minimal. This is a very shallow body of water so the use of motorized boats is nearly impossible, and the distance that the docks would have to extend would make them quite cost prohibitive. The changes in water levels would also require the deck of the dock to be elevated to the extent that wildlife would be able to cross under and possibly even use any docks as part of their habitat. Park Dedication: The current subdivision ordinance includes park dedication in the amount of $2075 per residential unit, less any land dedication. There is no land dedication needed, as Marshan Park is nearby. 411 Utilities: Sanitary sewer and water are stubbed to the property line on both the north and the south. The appropriate easements are platted for the connection of the church to the services that will be constructed as part of this plat. These and other issues discussed in the City Engineer review memo must be addressed to his satisfaction. Grading: The grading plan has been reviewed by the City Engineer and his comments will need to be addressed to his satisfaction prior to the site being developed. Environmental Board The Environmental Board reviewed the application on May 30th, there recommendations are attached. • • RECOMMENDATION Staff is recommending approval of this request, subject to the following conditions: 1. All lots in the plat must agree to connect to City utilities. The City will not approve the final plat without legally enforceable assurance that all properties will connect. 2. Issues discussed in the City Engineer review memo must be addressed to his satisfaction. 3. A development agreement between the city and the developer must be executed prior to the issuance of any building permits for the site. 4. Park dedication must be paid in accordance with the city's fee schedule. 5. A conservation easement shall be granted over the drainage and utility easement within the lots fronting Marshan Lake. Easement restrictions shall be defined prior to city council approval of the final plat. 6. The Rice Creek Watershed District must review the project prior to building permits being issued by the city for any new construction. 7. A boulevard tree shall be provided for each lot frontage. • 8. The existing roadway easement shall be vacated by the City Council prior to the approval of the final plat. • This review is based on the following plans and information: City Engineer Comments dated June 8, 2007 Environmental Board Comments from May 30, 2007 Grandview Plan Packet received May 14, 2007 • • LOTS /UNITS as of June 21, 2007 Development Name approved prelim. plats Prelim Plat Phasing plans by year (lots /units to be final platted) 2006 2007 2008 2 year end 2002 2003 2004 2005 Stoneybrook 103 51 2nd Addn 0 52 Century Farms North 249 56 65 52 43 33 Keefe: prel plat, not final plat 1 1 Morton (minor subdiv) 0 1 0 Ravens Hollow 56 0 56 Haley Manor (10 new lots) 10 10 0 Crystal Cove 3 3 0 Millers Crossroads 152 22 47 51 32 Lakeview Estates (2 new) 2 2 Snell (minor subdivision) 0 1 Pheasant Hills Pres. 13th 1 1 Justin's Preserve 1 1 Marshan Estates 4 4 Rice Creek Church duplex 2 2 Rice Church: Oakwood View 10 10 Junes Addn 2 2 Highland Meadows East 2nd 18 18 Marshan Townhomes 2nd 23 Pheasant Hills 12th island 8 8 West Shadow Ponds 2nd Add 1 1 Vaughan Addition 5 5 Angie's Acres (1 new) 1 1 Marshan Lakeview (2 new) 2 2 Marshan Meadows 20 20 Pine Glen 72 40 32 Cavegn (1 new lot) 1 1 Golden Acre (3 new lots) 3 3 Fran's Estate (1 new lot) 1 Cox Estate (1 new lot) 1 1 Grandview 7 new 7 Moon Marsh 3 new 3 total 51 148 176 171 141 77 remaining of annual 147 remaining of 1029 units for pre -2010 -1 -29 -24 6 70 147 • Memorandum DATE: June 8, 2007 TO: Paul Bengston FROM: James E.

A temporary sediment pond should be installed somewhere on the site that will accept construction water from storm events. 7. Developer shall prepare brochure for new home owners. The brochure should discuss the importance of water treatment and that some areas may be a bit wet after a storm. Other information should include Shoreland Overlay district restrictions on vegetation removal. City will review and approve document before being given to homeowner. 8. The developer has submitted a Storm Water Pollution Prevention Plan (SWPPP). The SWPPP must be approved and implemented prior to the commencement of a grading permit. A number of modifications to the SWPPP have been identified and will need to be incorporated into the final plan as identified in the attached SWPPP memo. 9. Developer should check with the Minnesota DNR on how to develop with National Heritage concerns in the area. • • • ENVIRONMENTAL 10. Because of the rare features concerns and the shoreland overlay district, a conservation easement should be drafted that is contiguous with that of Marshan Meadows. Literature shall be given to new residents notifying them of the easement and the reasons for it. Literature will be reviewed and approved by the City. Conservation easement signs should be placed along the easement line with at least one sign per frontage of easement. The sign should state that "no cutting, planting, filling or excavating should occur within the easement." 11. No soils should be imported or exported without city approval. 12. Verify delineation.

The proposal includes four residential lots on 25 acres of property. Mr. and Ms. Wessel currently reside in the existing home on the site. The project would create three more residential lots with a private loop road, a community sewage treatment system, and 12 acres of open space . Though the normal density in rural areas is one lot per ten acres, the zoning ordinance allows for up to eight units on forty acres in a PUD with a common septic system. (This translates to four units on the 25 -acre Wessel site.) This is allowed only in areas outside the growth areas defined in the Comprehensive Plan. The purpose is to provide for some development that preserves open space in areas that will not have municipal utilities. The zoning ordinance defines two types of PUD: rezoning and conditional use permit. A rural residential PUD can be approved as a conditional use permit. The site is within the area analyzed by the I -35E Alternative Urban Areawide Review (AUAR). The AUAR's mitigation plan requires some information and review criteria that are not normally applied to development projects elsewhere in the community. ANALYSIS The following summarizes the project proposal: Gross Site Area 25.3 acres Upland Area 11.1 acres Lots 4 Gross Density 0.16 units /acre Net Density 1.26 units /acre • • Moon Marsh page 2 Comprehensive Plan, Land Use, Zoning Location Existing Land Use Guided Land Use (Comp. Plan) Zoning Site rural residential Rural Rural North rural residential City of Columbus: Rural Res. /Agricul. City of Columbus: Rural Residential South regional park reserve Rural Rural East regional park reserve Rural Rural West rural Rural Rural Comprehensive Plan: The Comprehensive Plan guides the project site for Rural land use. The site is outside of both Stage 1 (pre -2010) and Stage 2 (pre -2020) growth areas and is well outside the Metropolitan Urban Service Area (MUSA). The Comprehensive Plan includes a policy stating that "density incentives may be considered in conjunction with a rural cluster subdivision that produces permanent open space." Another policy is to "promote rural residential clustering as a means of preserving greater amounts of open space or agricultural active lands." To implement these, the zoning ordinance provides for a rural residential PUD with a common septic system. A rural PUD must have at least 50% open space. The proposal includes 51% open space (Outlots C, D, and E). Rural residential PUDs are only allowed in areas such as this that are outside of planned growth areas. This is because growth areas are planned for municipal utilities and should be reserved for urban density growth. Rural lots of 10 acres are a way to hold areas for more dense development when utilities are available. In an area where there will be no utilities, even long term, there is no need to protect efficient service provision. The most important issue is ensuring enough land for onsite septic systems. A common treatment area ( drainfield) is an option that eliminates the need for primary and secondary drainfield areas on each lot. Growth Management: The Growth Management Policy (Ordinance No. 24 -04) limits the number of dwelling units that can be approved for platting annually. There are fewer than 80 units approved for 2007, leaving about 60+ for this year. The Moon Marsh project would create three new lots. The project includes several nature- friendly design elements, but this is not a "conservation development" as we typically use the term. It does not have a formally adopted stewardship (management) plan. Because we have ample units remaining for 2007 and this project creates only three new lots, there is no need to exempt the project from the annual limit. Zoning: The site is zoned Rural. The normal lot size requirement is 10 acres, and there are shoreland requirements to consider. However, a rural residential PUD with a common septic system can have up to eight units per 40 acres, or four per 20 acres. There is a minimum lot size of 25,000 sf for such a project. • • • Moon Marsh page 3 Shoreland: Shoreland overlay zoning covers land within 1000 feet of the Ordinary High Water Level (OHWL) of Rondeau Lake, classified as a "natural environment lake ". A shoreland overlay also applies within 300 feet of Rice Creek, but the creek is about 500 feet to the east. The OHWL for Rondeau Lake has not been determined. Lacking a specific determination, examination of the treeline often is used as the alternative method. The treeline is 100 -150 feet west of the road. By this reckoning, the Wessel property is within the shoreland overlay. However, shoreland requirements will have little effect on the site. Since all the proposed home sites are on the eastern part of the property, shoreland setbacks from the OHWL will not affect the proposal. The nearest building site will be more than 400' from the public roadway, well beyond the required 150' setback from the OHWL. There are no lakeshore lots, so visibility from the lake is not an issue. The shoreland ordinance was written well before current community septic systems technology, so lot sizes addressed only individual septic systems and municipal utilities. The current technology treats wastewater better than the typical public treatment plant. We are considering the "sewered" lot size in the shoreland ordinance as the appropriate one. There are no steep slopes on the property, so erosion down a bank into the lake or anywhere else is not a significant issue. In fact, very little site disturbance is proposed on the western part of the site. The ends of the private loop road and some culvert work are the only excavation activities near East Rondeau Lake Road. The site drains into Rice Creek and then to Peltier Lake and the chain of lakes, so water quality issues are pertinent. There are rain gardens designed into the project. The City has requirements for minimizing erosion that apply to all construction projects. In addition, the Rice Creek Watershed District examines and regulates impacts on wetlands and water quality. We forwarded the initial submittal to the MnDNR in January. An e -mail from MnDNR states they have no concerns and have the following comments: Rural Zone Shoreland: (sewered, nonriparian lot) PUD with common septic Proposed PUD lot size minimum 10,800 25,000 sf 33,000 sf to 93,000 sf lot width 330 = 80' 100' 250'+ along private road building setbacks from street rear lot line side lot line 30' 10' 10' Y�54= 25' same as zoning at project periphery 25' from private road 30' 15' from OHWL 150' bldg. height 35' 36'� t' per underlying reqs. impervious max. 65% 30% :' <20% (estimated) min. open space tt � � � ��, -�.� 50% 51% Shoreland: Shoreland overlay zoning covers land within 1000 feet of the Ordinary High Water Level (OHWL) of Rondeau Lake, classified as a "natural environment lake ".

The site drains into Rice Creek and then to Peltier Lake and the chain of lakes, so water quality issues are pertinent. There are rain gardens designed into the project. The City has requirements for minimizing erosion that apply to all construction projects. In addition, the Rice Creek Watershed District examines and regulates impacts on wetlands and water quality. We forwarded the initial submittal to the MnDNR in January. An e -mail from MnDNR states they have no concerns and have the following comments: • • Moon Marsh page 4 1. The proposed density falls easily within the statewide guidelines for development in shoreland areas. This entire parcel is within the shoreland district of Rondeau Lake. 2. The preservation of the open space, the filtration basins, and the curbless road section help lower this project's impact on the landscape. 3. The community septic system is not a concern if it will be monitored and maintained on a regular basis by a responsible party that has experience in the upkeep of similar utilities. Alternative Urban Areawide Review (AUAR): This site is within the area analyzed by the I -35E Corridor AUAR. Development within the area is subject to the mitigation plan adopted with the AUAR. The mitigation includes some specific, quantified requirements, but many of the requirements are means of achieving the best results possible, depending on the site. Conservation Development Framework: The Conservation Development Framework provides the foundation for most of the conservation objectives within the AUAR area. Implementation of the Framework will: conserve the most ecologically significant natural resources within the AUAR area (in particular, the "core" and "outlier" habitats); protect ecologically significant natural resources from adjacent land uses by implementing buffering; and connect ecologically significant natural resources via multi- functional greenway corridors. The goals of the Conservation Development Framework will be pursued through a variety of methods. The maps in the AUAR provide summary information and guidance. For example, the Minnesota Land Cover Classification System map (AUAR Fig. 10 -1) shows several cover types. The upland area where the new lots would be are classified as planted or cultivated vegetation, relating to the agriculture that has occurred. The existing driveway and house site show as artificial surfaces and associated areas. The western part, which corresponds to the large Outlot D wetland, is herbaceous and there are small forest areas where the wetlands are in the proposed Outlots E and C. These latter areas hold promise for preservation and merit special attention. The Wetland/Aquatic and Upland Habitats map (AUAR Fig. 10 -2) show the west wetland area as core wetland 7 aquatic habitat. It is these core areas that we want to preserve. Large core habitat areas can provide habitat for a wide range of wetland - dependent and aquatic species as well as rare natural features. Therefore, the larger wetland area as well as the other outlots will be protected with a conservation easement. This will preserve land adjacent to larger, off -site greenway areas to the east and south, which are part of the regional park. The conservation easement should provide for the possibility of future restoration work. Water quality, stormwater management, erosion and sedimentation: The AUAR includes analyses of surface water runoff issues which lead to requirements for including Moon Marsh page 5 infiltration elements and other techniques. It also includes estimated stormwater management recommendations for specific development areas. These estimates in the AUAR cannot be considered strict requirements because they were broad and based on general soil types and assumptions about impervious areas related to development. However, they do provide some guidance . The most general estimate is that 0 % -5% of the developable area would be needed for stormwater management (AUAR Fig. 17 -3). On a little less general estimate, the Moon Marsh site is labeled development area A -FR, with an estimated need of 0.13 acre (5660 sf) for stormwater management (AUAR Table 17 -5). The specific analysis and design for the project includes 4200 sf as infiltration basins. This falls within the broad estimate range and considering the scale of the site, is comparable to the less broad estimate. The AUAR requires that runoff rates will be at or below pre - development conditions. This is a standard requirement everywhere in the city, enforced on all projects. The AUAR also requires that runoff volume be no more that 150% of pre - development runoff. This is being reviewed. The groundwater elevation will determine how the proposed infiltration basins will function, which may affect the runoff volume. This will be analyzed as the project is reviewed further. Archaeological Survey: A Phase 1 archaeological survey was completed for the site and submitted with the project, as required by the AUAR. Records include an identified site to the east, but only low density artifact scatter was found on the Wessel site. The survey investigator does not recommend further evaluation. Rare Plant Survey: The AUAR mitigation plan states that due to the incidence of rare plant species in nearby wetland habitats, the City will require rare plant surveys and the mapping of rare plant locations prior to disturbance of areas of certain soil characteristics. The project site includes these soils. A rare plant survey is required and was performed on June 26. Several of the higher quality wetland habitats within the site contain suitable habitats for select rare plant species. However, no state- listed or otherwise rare plant species were detected. Planned Unit Development Section 2, Subd. 10. of the zoning ordinance includes the PUD standards. The zoning ordinance provides for two types of PUD. We have used a rezoning PUD on mixed use projects and others with exceptional design issues such as conservation developments in urbanized areas (with city utilities). We also have a provision for a conditional use permit for a PUD. A rural residential PUD is specifically designated for the conditional use permit PUD option. It is important to review the purpose and intent of a PUD. Subd. 10. PUD, Planned Unit Development. A. Purpose and intent. The purpose of this section of the Zoning Ordinance is to provide for the grouping of lots or buildings for development as an integrated, coordinated unit as opposed to traditional parcel by parcel, piecemeal, or sporadic approach to development. • Moon Marsh page 6 This section is intended to introduce flexibility of site design and architecture for the conservation of land and open space through clustering of Tots, buildings and activities, which promote the goals outlined in the Comprehensive Plan or serve another public purpose. It is further intended that planned unit developments are to be characterized by central management, integrated planning and architecture, joint and common use and maintenance of parking, open space and other similar facilities, and harmonious selection and efficient distribution of uses. ... The PUD, by allowing deviation from the strict provisions of this Ordinance related to setbacks, heights, lot area, width and depths, yards, etc., by conditional use permit or a mixture of uses by rezoning to a PUD District, is intended to encourage: 1. A development pattern in harmony with the objectives of the Comprehensive Plan. 2. Innovations in development that address growing demands for all styles of economic expansion, greater variety in type, design, architectural standards, and siting of structures through the conservation and more efficient use of land in such developments. 3. The preservation and enhancement of desirable site characteristics such as existing vegetation, natural topography and geologic features and the prevention of soil erosion. 4. A creative use of land and related physical development which allows a phased and orderly transition of varying land uses in close proximity to each other. 5. An efficient use of land resulting in smaller networks of utilities and streets thereby lowering development costs and public investments. 6. Promotion of a desirable and creative environment that might be prevented through the strict application of City zoning and subdivision regulations. C. Rural Residential Planned Unit Development Requirements. 1. Purpose. It is the intent of this section to establish special requirements for the granting of a conditional use permit for rural (without City water or sanitary sewer) residential conservation subdivision PUD project in order to promote: a. Preservation of productive land for agricultural use. b. Preservation of wildlife habitat and unique natural resources. c. Reduction of negative impacts on the environment d. Creation of common open space that provides a unified landscape for the use and enjoyment of the neighborhood community and/or the general public. e. A variety of rural residential lot sizes, configurations, and neighborhoods. Density: Normal density in the Rural land use category is one unit per ten acres. However, the PUD standards allow eight units per forty acres in a subdivision that is served by a community sewer system that is approved by the Minnesota Pollution Control Agency (MPCA). • • • Moon Marsh page 7 Lots: The lots are clustered to avoid wetland impacts and provide efficient access to the community septic absorption field. The effect is a small neighborhood that is so isolated from the public road it will not even be visible. With the 10' easement around the wetlands, the house pads on a couple lots are within about 11' of the easement. It likely is possible to move the pad on L B3 to the northwest to provide more use of the yard around the house without encroaching on the easement. Similarly, the pad on L2 B2 could move slightly to the south. While retaining the windrow of trees is desirable, many of the trees will be lost anyway when the septic tanks are installed on the south side of the lot. The pad locations should be re- examined and, if possible, moved to allow more distance from the easements. The new pad locations must be shown on plans prior to construction. One outstanding issue is the groundwater elevation. Submitted data is somewhat inconsistent. Low floor elevations and stormwater facilities are compared to groundwater level. Floor pads must be four feet above groundwater, and the bottom of ponds and infiltration basins must be above groundwater enough to function properly. While we can agree on a `worst case scenario' elevation to determine house pad elevations, this level needs to be compared to the submitted grading plan and analyzed for stormwater management purposes (see below). Water: Each home will have individual wells for water. The wells must meet minimum separations from septic system facilities. This will be addressed with well permits from the MN Dept. of Health. Sewage Treatment: The development uses a sophisticated sewage treatment system that includes both individual treatment and a community mound. Most treatment will occur within the multiple tank- and - treatment facilities on each lot. This allows for monitoring and maintenance of individual lots without interfering with the elements of the system used by all lots. It also minimizes the treatment that is needed in the common mound absorption field. total acres wetland acres upland acres Lot 1, Block 1 2.63 0.48 2.15 Lot 1, Block 2 2.00 1.13 0.87 Lot 2, Block 2 2.00 1.24 0.76 Lot 1, Block 3 2.00 0.90 1.10 Outlot A (septic site) 1.03 0.00 1.03 Outlot B (private road) 2.78 0.32 2.46 Outlot C 2.10 1.31 0.79 Outlot D 6.43 6.20 0.23 Outlot E 326 2.52 0.74 E Rondeau Lk Rd ROW to be dedicated 1.05 0.09 0.96 total 25.28 14.19 11.09 With the 10' easement around the wetlands, the house pads on a couple lots are within about 11' of the easement.

We will need to require pumping of individual tanks if only one home is built at first. The details will need to be determined. Wetlands and Stormwater Management: The Rice Creek Watershed District (RCWD) has approved the delineation of the wetlands on the site and the mitigation plan. The wetland complex to the east of the site, which corresponds with Rick Creek, is DNR protected wetland 740W. Wetland #4 in the southeast corner of the Moon Marsh site is part of this complex. The proposal would fill 4200 sf of wetland along the roads and mitigate this with 4200 sf of new wetland and 4200 sf of public value credits in the form of infiltration basins. The design and implementation must comply with RCWD requirements. Two infiltration basins are proposed, one on the north side of the site along the road, one on the south side. These are being reviewed to determine if the soils and basin designs will function properly. The groundwater depth is relevant to this analysis. Drainage and utility easements will be established that cover and extend 10' beyond the wetlands, in accordance with City requirements. Conservation easement locations will correspond to these drainage and utility easements. F000dplain: The FEMA floodplain map shows much of the site within the 100 -year floodplain. The RCWD has determined the 100 -year elevation to be 887.5. Lowest floor elevations are at least two feet above this in accordance with City policy. There will be minor floodplain fill which will be addressed by excavating an area of equal volume to compensate (compensatory storage). Roads, Access, Traffic: The proposal extends the existing driveway on the south part of the site to become a private loop road with another access onto East Rondeau Lake Road. This private road serves all four lots. Because heavy vegetation can block sightlines, a certain area should be cleared where the loop accesses East Rondeau Lake Road. The right of way for the east 33 feet of East Rondeau Lake Road will be dedicated with the plat. The road is an easement now. This will be clarified with the title search that will be necessary for a final plat. The creation of three new residential lots will not create a traffic generation problem. Park Plan and Dedication: The parks plan shows Natural Resource Protection Areas corresponding to the locations of wetlands as revealed by the wetland delineation.. These are wetland areas that will be protected by existing wetland law or may be important plant communities. They will be covered by a conservation easement as well as a drainage and utility easement. • • • Moon Marsh page 9 The Natural Resource Conservation Areas are uplands with features that have high ecological value. These areas should be examined for the potential for protection. The rare plant survey found no rare species in the uplands on the site, and most of these areas have been disturbed by past use. Park dedication will be cash in the amount of $2075 for each of the three new lots, for a total of $6225. ENVIRONMENTAL BOARD ACTION The Environmental Board reviewed the project on June 27th. Their comments are attached. Overall, the Environmental Board was positive about the project. OPTIONS 1. Open public hearing, take comment, continue public hearing to August 8th. 2. Recommend approval of application. 3. Recommend denial of application. RECOMMENDATION Option 1: continue public hearing to allow for submittal of additional information.

An existing conditions plan is required to be submitted for review. 3. A letter report was included but not the soil boring logs. 4. See attached drainage review dated July 3, 2007. Additional Comments: 1. Please note this is a private project City engineering standards are not being met (20 foot gravel road and community septic system for lots less than 10 acres); therefore the city will not take ownership of the improvements made to this project Items to be addressed prior to final approval: 1. A field review of the site distances at the two intersections will be needed to confirm tree clearing and any advanced warning signs that might be necessary. I 2. The additional treatment shown for the septic system may or may not be required for this system. We will not know until a full site evaluation is submitted. If the additional treatment is required, the system would be a "performance" type system. Because the City has not specifically adopted the performance section of Minnesota Rules 7080, they are not permitted.

Drainage Review City of Lino Lakes, Minnesota From: Connie J. Tail Ion, P.E. Proj. No.: 13810.002 Date: July 3, 2007 Routing: The following drainage review is based on these submittals: 1. Moon Marsh Preliminary Grading, Drainage, and Erosion Control Plans, and Storm Water Pollution Prevention Plan submitted by Hult & Associates, Inc., dated October 4, 2006. 2. Moon Marsh Drainage Report submitted by Hult & Associates, Inc., dated January 2007. New comments are in bold and identify items that need to be addressed. The following are significant issues that must be addressed prior to preliminary plat approval: 1. Submit a geotechnical report summarizing the seasonal high water mark which is identified as the mottled soils or highest anticipated waxer table. The lowest floor elevation is required to be 4 feet above the seasonal high waxer mark. It appears from the percolation report that mottled soils have been encountered in the test area between 12" to 20" below the ground surface. 06/19/07 The Geotechnical Report indicates that groundwater was found in the vicinity of 886± to 888.5 ±. The report goes on to state that `it is unlikely that this investigation has found groundwater at its highest leveL Most likely, maximum groundwater on the site is equivalent to the ordinary high water level (not short term flood level) of the vicinity wetland'. A seasonal high water mark has not been identified in the report and will need to be submitted. Based on the groundwater levels determined in the Geotechnical Report, Lots 1 and 2, Block 1, does not meet the City's minimum low floor requirement as stated in comment 1 above. 2. The filtration areas may not be feasible due to the presence of mottled soils near the surface which indicates high ground water levels. Groundwater could affect the efficiency of these systems. 3. Submit existing and proposed watershed maps and label each subwatershed so that the map corresponds with the HydroCAD model. 06/19/07 This item has been addressed. 4. Identify the location and elevation of the outlet and emergency overflow for all wetlands. Low openings are required to be a minimum of 1 foot above the emergency overflow elevation. 06/19/07 It appears that the emergency overflow for wetland No. 1, at the north end of the site, is located at the low point of the proposed road at station 19+00. The new overflow created by the construction of the road appears to be at a higher elevation than the overflow elevation for this wetland under existing conditions. Identify the overland emergency overflow Moon March Drainage Calculations Review II City of Lino Lakes, Minnesota 1 July 3, 2007 elevation for wetland No. 1 located at the north end of the site on the Plan and ensure that the low opening of the existing home located north of the site is a minimum of 1 foot above the new emergency overflow elevation. Label the emergency overflow elevation for wetland No. 3 and wetland No. 4 on the Grading Plan. 5. Supply design computations for the proposed culverts connecting the wetlands at the north and south end of the site. Show that the proposed high water levels of the existing wetlands are equal to existing high water levels. 06/19/17 This item has been addressed. See below for additional comments regarding the model. Additional Comments (06/19/07) 6. The sum of the total wetland area defined in ponds 1013 and 12P of the model should equal the wetland area of the existing wetland defined in pond 11P. For example, the area of the wetland at elevation 888 under existing conditions in pond 11P is 10.1 acres; however, the sum of the area at elevation 888 under proposed conditions for ponds 10P and 11P is 17 acres. 7. The filtration basin 2P and 4P outlet device routing is not consistent with the outlet structure detail on Sheet 7. The 12 inch horizontal orifice/grate should be routed through a 12 inch diameter outlet, not the 4 inch diameter pipe as currently modeled. In addition, the 4 inch outlet should be a 6 inch outlet at a 0.0% slope, with the length as labeled on the Grading Plan and outlet structure detail. Update for consistency. Runoff rates will be checked when the revised model is submitted for review. 8. Identify the HWL and location and elevation of the emergency overflow for all culverts on the Plan. Low floors are required to be 2 feet above the 100 -year elevation of all culverts. The following are minor plan, calculations, and drafting corrections that must be addressed prior to final approval: 1. The low opening of Lot 1, Block 3 is required to be 1 foot above the emergency overflow of filtration basin 2. 06/19/07 This item has been addressed. 2. A 10 foot buffer of undisturbed vegetation is required from the delineated edge of the existing wetlands. Show the wetland bnfFer on the Plans. If grading occurs within the buffer, the area shall be restored with native vegetation. 06/19/07 This item has been addressed. e3. Include notes on the grading plan incorporating the following: 1.) complete impervious area construction and stabilize pervious areas prior to introduction of stormwater into the filtration practices, and 2.) final grading of the filtration areas should be completed using light tracked equipment to avoid compaction of the basin floor. 13810.002 Moon March Drainage Calculations Review City of Lino Lakes, Minnesota 06/19/07 This item has been addressed. July 3, 2007 4. To provide a well aerated, highly porous surface, the soils of the filtration basin floor should be loosened to a depth of at least 12 inches prior to planting. 06/19/07 This item has been addressed. 5. It is highly recommended that mature plants be used over seed in the filtration basins. Fluctuating water levels cause seed to float and be transported downstream of the filtration basins. In addition, it may take up to two growing seasons to establish the function and aesthetic value of mature vegetation using seeds. 6. Label the normal water level and high water level of the existing wetlands on the Plan. 06/19/07 This item has been addressed. 7. Label the inverts and size of the existing culvert located under the existing gravel driveway. 06/19/07 This item has been addressed. • a. • Submit a copy of the NPDES permit for the City's records when available. 9. Approval from Rice Creek Watershed District (RCWD) is required. Submit a copy of the RCWD Permit when available. Additional Comments (06/19/07) 10. Use the existing culvert length and invert elevations for the outlet of wetland No. 1 in the existing conditions model 11. Clarify why the watershed area flowing to the east under proposed conditions (subcatchment 6S) has a longer time of concentration than under existing conditions ( subcatchment 7S). 12. Provide a berm north of the low point of the ditch located on the north side of the proposed road at station 6 +50 that will fully contain the 100 -year storm event. Label the elevation of the top of berm on the Grading Plan. 13. Show the location of soil borings 5 - 7, and label all soil boring numbers on the Grading Plan. 14. Clarify how the off -site watershed boundary to the north was determined. 15.

This development , although not called a "conservation development', should employ the guidelines of the AUAR. 2. A conservation easement containing no-mow , dumping, cutting, building in, or filling in , and naming the City as the easement holder with the right to perform restoration work in the easement. This easement should be written from the wetland edge and cover as much as possible of the area shown in Attachment 10. Signs should be posted on the easement line , describing the easement , every 50 feet 3. SMA's within the AUAR and therefore in Moon Marsh must have: • No more than 20% of their surface as permanent open water, the remaining surface area of each SMA shall contain mesic prairie or wet prairie communities to maximize the infiltration and water quality treatment capacities of the system • Design high water levels (100 -year) less than or equal to 2.5 feet above the normal water level or lowest outlet invert • Side slopes that are less than or equal to 6:1. horizontal to vertical and 10:1 safety bench at the normal water level per RCWD requirements. • Post development runoff release volumes should be no less than 80% and no greater than 150% of existing conditions runoff volumes. These standards must be verified by our City Engineer 4. RCWD CAPROC Items are addressed including and particularity: Geotechnical soil borings at proposed BMP location in order to determine depth to the water table. This is important in that the designer is calling these infiltration ponds. Infiltration ponds designed into the groundwater are not infiltrating anything other than possible contaminants to the ground water. Adequate separation (3 ") must be shown between the pond bottom and the ordinary high ground water. A number of Wetland, Erosion and sediment control, Administrative, findings and stipulations as outlined in the CAPROC Attachment • Page 1 • • 5. there is enough indication that there could be rare plants on part of the property, and the property should be surveyed to verify the presence or absence of rare plants. The area on the Wessel property that would be of concern is indicated on Attachment 10. 6. Suggest placing the buffer of the westem most wetland in Conservation easement since this forms part of the City Greenway system (Attachment 11). New wetlands constructed on the site as well as buffer areas should be planted with the City native seed mix. 7. Rain gardens proposed on the site should be designed with a low maintenance (unless there is agreement with new homeowners to manage something different) Maplewood - type of design. Design of these gardens should be submitted to the city as well as a perpetual maintenance plan. All designed ponds and infiltration features must have at least 3 -feet of sand separation between the ordinary high ground water level and the bottom of the structures. 8. Community drainfield should be approved by Anoka County Environmental 9. It is recommended that a temporary sediment pond be constructed to capture surface water runoff during construction. All proposed infiltration, wetland and rain- garden soils must be protected during construction. Suggest construction of new surface water features after major construction is complete. Features should be constructed with low impact/compaction, track -types of equipment and fenced off prior to construction. All soils determined to be more compact after construction than prior to construction in drainage/ surface water infiltration or management area will be loosed to pre - construction conditions. It is also recommended that all new yard soils have top -soil incorporated into the subsoil and tilled as deeply as possible. No soil may be imported or exported with out City approval. 10. . Recommended changes to the SWPPP are submitted to the City Engineer to make changes to the documents submitted. Changes should include City native seed mix in all final grade stabilization, and installed by a DNR listed contractor. • • COMPREHENSIVE PLAN PROPOSED LAND USE, (detail) • • • ZONING MAP (detail) • • I I: la, - • - • COMPREHENSIVE PLAN PROPOSED LAND USE, AUAR BORDER, AND FUTURE ROADS (detail of AUAR Figure 6 -2: Scenario 1) MOON MARSH SITE AUAR STUDY AREA • • EAST RQk DEAUfLAKE ROAD CITY OF LINO LAKES Ci • • PESCRIPT/ON OF EXISTING PROPERTY: That part of the Northwest Duarter of the Northwest Duarter, Section 2, Township 31 North, Ronge 22 West, Anoka County, Minnesota. lying South of the North 550 feet thereof and lying easterly of the center line of East Rondeau Loke Drive as descrbed on a Warranty Deed recorded in Book 555 of Deeds, poge 395.
