Recommend, by motion, approval of the Preliminary Plat for The Pines at Elk River. 4A UR Background /Discussion The applicant, Roger Derrick with the Pines at Elk River, LLC, purchased two adjoining parcels on 183rd Circle NW and is proposing to develop both parcels as 26 detached townhome units. The project will be similar to the West Oaks project, which was also developed by Roger Derrick. Some units will have the option for a walkout basement. Kliever Lake Fields and Miske Meadows have also included detached townhome units similar to those proposed with this project. Comprehensive Plan The Comprehensive Plan guides this area as Mixed Use which allows a mixture of housing, jobs and /or retail services uses within close proximity to each other. The area also provides another setting for high density residential land uses. The proposed use and rezoning is supported by the comprehensive plan. The applicant had hoped to develop the area with higher density residential uses, but the road network does not support the traffic generated by such a use. Site Plan The 26 townhome lots are laid out along two private streets, both of which access 183rd Circle NW. The parcels and placement of the homes have been planned to minimize impacts to existing trees on the site, buffering the homes from view along Twin Lakes Road and 183rd Circle. Each home will have driveway access to a private street, and no additional access points to public rights -of -way are proposed. Townhome standards require one -half guest parking space per unit in an off -street parking lot or private drive. The private streets appear to provide this standard, but an exhibit demonstrating compliance must be submitted. The existing drainage pond on the south side of the site will be utilized for the development. The wetland was not delineated as there is not any proposed development south of the drainage pond. Engineering and Utilities In conjunction with the tree preservation goals, minimal grading to the site has been proposed. Most of the grading will take place in the center of the site, and the perimeters will be minimally changed. Properties are graded to direct runoff to the private streets, which collect stormwater via catch basins, and to the rear of the property. Stormwater collected in the streets is directed to the existing stormwater pond which was constructed as part of the previous plats. All homes will be served by city sewer and water. Landscaping The proposed landscape plan shows a number of trees along the private streets, and between the townhomes. An updated landscaping plan demonstrating compliance with Sec. 30 -994 (h) must be submitted. Parks Park dedication was satisfied with previous plats in this area, and will not be collected as part of this project. \ \dc3 -elks \shared \Departments \Community Development \Planning \Case Files \P \P 17 -09 The Pines at Elk River \4Planning Commission \P 17- 09 Pines at Elk River.docx Applicable Regulations Zone Change In review in a proposed amendment, consideration shall be given to existing conditions avithin the area directly and in affected by the proposal, the conservation of proper ty values, the use to avhich the property affected is being devoted at the time, and relevant provisions, if any, in the land use plan.

We are proposing to develop the property into 26 detached townhome lots. The Pines will be similar to West Oaks in that each townhome will be detached and will offer buyers a choice of the Bridgeport or Wellington designs, with and without sunrooms. Buyers can also choose their homes to be slab -on -grade or have walk -out basements. The property is heavily wooded with towering pines. We have designed several lot plans in an attempt to limit the number of trees that must be removed for construction. That effort has reduced our original 31 lot plan to 26 lots. This allows us to keep the development on the flat part of the property, away from the hillsides, and limit the amount of roadway needed. We are all very excited about The Pines development and believe it will be a valuable asset to the community. Thank you for considering our proposal.

Project Duration: Anticipated 90 Days Potential Dischorges: Sediment resulting from construction operations. Are. to be Disturbed: 5.0 Acres Pre — Construction Impervious Area: 0.0 Acres Post Construction Impervious Area 1.71 Acres New Impervious Area: 1.71 Acres RECEIVING WATERS Receiving Waters Within One Mile: Troll Brook is not o special or impoiretl water Mississippi River is o special and on impaired water PLANS AND SPECIFICATIONS The plan sheets of this plan set indicate the following items: The project location and construction limits. Existing and final grades. Tributary are. dividing lines and direction of 71D. for all pre an at post — construction stormwoter runoff drainage are provided in the tlroinoge role ul.lions. Drainage calculations are provided upan r request by Bogart, Pederson & Assoc. Locations of impervious surfaces. Locations of areas not to be disturbed (e.g., buffer zones, wetlontls, etc.). Steep slope locations. Loco ions of all temporary and permanent erosion and sediment control BMP's to be installed on the project. The detail sheets indicate erosion nd sediment control BMPS to be installed on the P roject. Estimated quantities "(Drone ontl sediment control features for this project ore indicated in the plans ontl in the bid proposal form D1 the Project Manual. I. Infiltration area shall be staked off during construction to restrict heavy equipment troffic from compacting native soils. 2. Install appropriate temporary erosion devices to prevent sediment from leaving or entering the pr.ctice during construction. 3. Construct and vegetate bioretenti.n device following stabilization of contributing tlroinoge ore.. 4. Grading of the infiltration basin shall be accomplished using IDw— impost earth— moving equipment to prevent comps lion of the underlying soils. Small hacked dozers and bobcats with runner tracks are recommended. 5. Excovole the infiltration basin to the specified depth (elevation). It is recommended that all sub material below the specified elevation shall be undisturbed. 5. In the event that sediment is introduced into the bmp during or immediately following ovation, this material shall be removed from the practice prior to continuing construction. 7. Remove temporary erosion control devices after the contributing drainage ore. is .tlequ.tely vegel.ted. Down gradient silt fence ontl sediment log installations are to be inplace prior to the cam mentem ent of any earthwork operations. Topsoil is to be windrowed "long the construction limits and placed as slope dressing immediately following completion of the grading operations, as the grading operations proceed. Topsoil placement along the embankment slopes though the wetlontls are. is to be spread by o low impact c .wler tractor operating up and down the slopes so as to provide track prints parallel with the contours. Installation of Mn /DOT Category 3 Erosion Control Blanket along the embankment Slopes adjacent the wetlontls ore.. All temporary soils stockpiles will require an effective m of sediment control such o n erosion control Dl.nkel Covering or silt fenced nstallation along the toe of slope. a All completed ditch slopes and bottoms not draining towards the wetlontls area ore to be stabilized within 7 days. Temporary stabilization will be required in are.. here grading operations are suspended or ceased for o period of 7 day. or greater. A rock construction entrance for sediment control is to be provided at the project drive..ys. Street s eeping of the paved surfaces will be required as directed by the Engineer. Tracked sediments must be removed from II paved surfaces, adjacent roodwoys, and other off —site areas within 24 hours of discovery. TIMING EROSION CONTROL Silt fence will be installed prior to construction Riprop and tiller blanket will be placed at the outlets within 24 hours of the outlet placement. The contractor must stabilize the all exposed soil areas immediately following construction wherever Construction will not occur for o period greater than or equal to 7 days. Stabilization work must be complete within 7 c.lender tloys after the construction work in that ore. has temporarily or permanently ce.sed. Arens that o within 2DD ft of o Public Water must be stabilized within 24 hourrs of completing construction during periods of "Work in water rest riclions" for time periods declared by the DNR. The Contractor is esponsible to maintain the disturbed .re. until vegetation in established. Once vegetation is established and construction is complete, the silt fence and any other temporary erosion control that is not biodegradable shall be removed. Street sweeping ill be provided on as directed by the Owner The City may require the Owner to provide Street s eeping. If so the Sireet sweeping must occur within B hours of of notice from the City. Applying mulch, hydr.mul.h, t.ckifier, p.1y.cryl.mide or similar erosion prevention practices is not acceptable stabilization in any port of o temporary or permanent drainage ditch or ...le. INSPECTION AND MAINTENANCE ACTIVITIES The Contractor is to provide o trained intlivitluol responsible Tor the implementation, inspection ontl maintenance of the erns n ontl setlimenl control BMPS on the project. That individual is to be identified at the pre — construction c onterence and listed in the minutes thereof. The appointed individual is to perform o routine inspection of the entire site at least once every seven days during construction operations and within 24 hours otter o rainfall event greater than 0.5 inches in 24 hours. A recommended inspection form will be provided to the Contractor of the pr—construction conference. Any deficiencies in the erosion and sediment control BMPS are to be noted on the inspection form and corrected by the end of the next business day. Perimeter control devices are to be repaired or replaced when they are no longer effective or when the sediment reaches one —half the height of the device. POLLUTION PREVENTION Fertilizers are to be applied only in the amounts as specified and worked into the soil to minimize exposure to stormwoter runoff. Onsile refueling operations o e to be conducted with c Any inodvertenl spillage of to el or chemicals is to be immediately cleaned up, removed from the site ontl disposed of in accordance to State and Local Regulations. Major spills are to be reported to the MPCA 24 Hour Notification network at 800 422 0798. All vehicles nsite o e to be monitored for leaks and subject to routine preventive maintenance efforts to reduce the likelihood of leakage and or spills. Portable sanitary waste facilities are to be provided onsite and emptied on o bi— weekly basis. Concrete botch trucks will not be .11—cl to discharge drum and chute ..shout directly on the ground. A portable ..shout receptacle is to be provitletl by the Contractor at the location as provided by the Owner. FINAL STABILIZATION Final m, Stabilization o re when 70 percent of the pervious area is covered with uniform, permanent vegetation. All temporary erosion and sediment control features are to be removed and the NPDES Notice of Termination is to be prepared and submitted to the MPCA.
