6.3. SR 02-20-2001City of E River MEMORANDUM Item # 6.3. TO: FROM: DATE: SUBJECT: Mayor and City Council Scott Harlicker, Senior PlanneF'~ February 20, 2001 Case No. P 01-01 Request by Dynamics Design & Land Company and Thomas Hartman for Preliminary Plat- Fox Haven Request Consider a request by Dynamics Design and Land Company for a single family residential preliminary plat of Fox Haven (19 lots). Location The property is located north of 185th Avenue, south of Lake Orono and west of Guardian Angels West. Zon~q/Land Use Rlc (Single Family Residential) / MR (Medium Density Residential) At~chmen~ · Location map · Preliminary plat · Preliminary grading plan · Memo from the City Engineer Overview The applicant proposes to plat 24.33 acres into 19 single family lots and 6 outlots. There is an existing single family residence on the property that will remain on one of the newly platted lots. The property is fairly level with woods on the east and west sides. The central portion of the property and the north end of the site are open. There is a small hill at the north end of the property on which 13065 Orono Parkway · P.O. Box 490 · Elk River, MN 55330 · TDD & Phone (763) 441-7420 · Fax (763) 441-7425 Memo to Mayor and City Council/P01-01 February 20, 2001 Page 2 the existing house is located. The property has frontage on Lake Orono and on 185th Avenue. Access into the site is from 185th Avenue. The general layout of the plat is a loop road with the lots fronting on the outside of the loop and the inside of the loop being common open space. Five lots and one outlot will have frontage on Lake Orono. The property is within the urban service area and the lots will be connected to municipal sewer and water. Layout Streets The main street through the plat is a loop road with a formal divided entrance and exit from 185th Avenue. The applicant is proposing one-way traffic flow around the loop. There will be a connection about midway through the loop to allow for cross-over traffic. This connection will allow residents that live near the exit of the development an opportunity to avoid driving all the way around the loop to get to their driveway. The applicant is proposing a 50 foot wide right-of-way and 20 foot wide roadway. By having a narrower right-of-way, the developer is able to keep the house pads out of the trees and preserve more of the trees on site. The 20 foot wide roadway is wide enough to allow for one-way traffic. Typically with two-way traffic the city requires roadways that are about 32 feet wide. The development will have concrete curbs and gutters. The developer is proposing a 6 foot wide concrete sidewalk on the dwelling side of the loop road. Lots The development includes 19 single family lots. The existing house will be located on one of the lots. All of the lots exceed the 11,000 square foot minimum lots size. Most of the lots(16) exceed 20,000 square feet in size. All of the lots have frontage and access from the loop road. Six of the lots and one outlot have lake frontage. Five of the six outlots will be owned and maintained by a homeowners association. Outlots A and E will provide a landscaped buffer along 185th Avenue. Outlot B is the median on the entrance drive. Outlot C is the center island of the loop road and will include a stormwater retention pond. Outlot D will provide access to Lake Orono. Residents will be allowed to launch watercraft, such as canoes, from this outlot. The number of boat slips and docks allowed on this outlot is controlled by the Shoreline Ordinance and is based on the width of the lot. Outlot F will be platted at some time in the future as two single family lots and will be owned by the developer. S:\PLANNING\SCOTT~P0101 CC. DOC Memo to Mayor and City Council/P01-01 February 20, 2001 Page 3 Shoreline Manaqement Ordinance The project has been compared to the rules and regulations found in the Shoreline Management Ordinance. The project complies with those rules and regulations. Outlot D is being proposed to allow property owners that do not have lake frontage access to the lake. It will have to be widened so that it measures 80 feet wide at the front yard setback. Six property owners will have deeded access to the lake from Outlot D. The applicant has indicated that the first six property owners that would like the boat slips included in the purchase price of their lots will be the ones allowed dock space on Outlot D. The number of boat slips or docks allowed on Outlot D is six. The plat was also sent to the DNR for comments. Grading, Drainage1 Utilities and Erosion Control The City Engineer has reviewed the grading and drainage plan. Issues relating grading, drainage, utilities and erosion control can be found in his attached memo. The lots will be connected to municipal sewer and water. Tree Preservation Most of the trees located near the center of the site will be removed with construction. The trees to be saved are located in the rear of Lots 3, 4, 5 and 6, Block 1 and the rear of Lots 2, 3, 4, 5 and 6, Block 2. Lots 3, 4, 5 and 6, Block 1 will also be custom graded which should allow for additional tree preservation on those lots. The preservation plan should be revised to include the area that will be graded for the enlarge stormwater pond located on the east boundary of the plat. All trees shown as preserved shall be protected prior to site clearing or grading by fencing the drip line of protected trees and grading limits with a snow fence to prevent unnecessary grading, compaction or storage of debris or equipment. Parks and Trails No parks or trails are proposed for this 'project. Park dedication requirements will be met with a cash dedication for 18 lots. Landscaping The proposed landscape plan includes a mix of red maples and white ash trees. One street tree is proposed for each lot. The zoning code requires one street tree and a front yard tree for each lot. An additional front yard tree will be required on each of the lots. Trees are also proposed for the entrance drive median and the berm along 185th Avenue.

Box 490 Elk River, MN 55330-0490 RE: FOX HAVEN ADDITION Dear Ms. McPherson: As requested, we have reviewed the submittal package for the Fox Haven Addition. The submittal package consisted of a preliminary plat, preliminary grading plan, and preliminary landscape plan, all prepared by John Oliver and Associates, with a revision date of January 10, 2001. As you are aware, the Fox Haven Addition is the proposed plat of the Tom Hartman property north of TH 10, just west of the Guardian Angels site on the Elk River. It consists of 19 lots, including a lot which contains the existing Hartman house. Based upon our review and a meeting with the Developer, we would offer the following comments: The road serving the 19 lots accesses 185th Avenue. The ingress and egress off of 185th Avenue is divided by Outlot B. Towards the river, the road goes around a large Outlot C intended for ponding purposes. It is our understanding that the traffic around Outlot C is intended to be one-way only. There is a cross-over between Outlots C and B that will allow vehicles to cross over and continue their tdp around Outlot C or exit the plat. The road has some relatively sharp curves and comers in it, but the intent is to create a unique neighborhood with the Outlots being landscaped to screen the majodty of the lots' view of 185th Avenue and TH 10. Given the limited number of lots off of this road system and the lack of any cut-through traffic, we believe the road system will operate effectively and safely, even with the sharp curves and comers. No drainage calculations have been provided at this time. However, the drainage concept consists of a large pond in Outlot C where most of the street drainage will be conveyed. From Outlot C, where the quality control and rate control of the runoff will take place, the overflow will be conveyed eastedy to an expanded pond on the boundary between the Hartman and Guardian Angels properties. From here, there is an existing, large diameter pipe that carries flows from this pond to Lake Orono. 3. Sanitary sewer service will be provided by extending service into the plat from 185th Avenue. Given the elevation of some of the lots adjacent to the Elk River, a lift station will be necessary to provide service to these homes. Watermain will be looped through the site from 185th Avenue and connecting to the existing watermain to the east in the Guardian Angels development. VVatermain should also be stubbed westerly between Lots 6 and 7, Block 2, to provide for looping to the west at some point in the future. O:~PROJ~810640J\0240~.tr 01-16-01 McPherson.doc 1326 Energy Park Drive · St. Paul, MN 55108 · 651/644-4389 fax 651/644-9446 toll free 888/368-4389 Ms. Michele McPherson January 16, 2001 Page Two 4. The grading plan provides for minimal grading outside of the street and outlot area. Outlots A and E will provide for berming along 185th Avenue. Lots 4, 5, 6, and 7, Block 1, are indicated to be custom graded lots at the time of home construction. This area is heavily wooded with evergreen trees. The proposed contours are shown on these lots to indicate how full basement or split walkouts could be constructed. It is reasonable to leave the grading on these lots until the time at which the home style and size can be determined to minimize the tree removal. Outlot D is intended to provide access for the plat to the Elk River. It is the intent to construct a dock and boat slips for use by the residents in the addition. The Developers are working with the DNR to determine what will be allowed with regard to boat dockage. The typical street section shown on the preliminary grading plan is adequate for its width which is 20 feet face to face. This is the minimal width for a one-way street due to maintenance requirements and emergency vehicle requirements. The street cross-section should show 2 inches rather than 1% inches of bituminous base course. Also, the sidewalk shown on the street section should be six feet wide rather than five feet wide. Outlot F, which is in the comer of Naples Street and 186th Avenue could accommodate two additional lots. We have talked to the Developers and indicated that if they pursue the platting of these lots at this time, we would recommend paving Naples Street across the frontage of these two lots. The two lots would also require the extension of sanitary sewer and water along Naples for approximately 230 feet to service them. Apparently, the Developers are going to wait on the platting of these two lots until a project can be undertaken for the whole Naples Street/186th Avenue neighborhood. o It is our understanding that there will be a Homeowners Association for the care and ownership of Outlots A, B, C, D, and E so that the City will have no responsibility for ownership or maintenance of these areas. We assume that Outlot F will be held by the Developers for the future platting of the two lots in this area. If you have any questions regarding these comments, please call. Sincerely, Howard R.
