HomeMy WebLinkAboutItem 08 Date: Item No. SUMMERS CREEK FINAL PLAT AND EASEMENT VACATION Proposed Action Staff recommends adoption of the following motion: Move to approve: 1) a resolution approving the Summers Creek final plat, and 2) a resolution approving the easement vacation. Overview Summergate Companies has submitted final plat and easement vacation applications and plans for 46 single family lots and 65 detached townhome lots on 92.96 acres of land located south of Dodd Boulevard (CSAH 9), east of Highview Avenue, and west of Cedar Avenue (CSAH 23). The Summers Creek preliminary plat of 84 single family and 127 detached townhome lots was approved by the City Council on August 5, 2019. The Summers Creek final plat is consistent with the approved preliminary plat. The drainage and utility easement to be vacated was established in 2013 in conjunction with the Dodd Boulevard (CSAH 9) and Highview Avenue roundabout construction and was in favor of Dakota County. The easement covers a stormwater pond located south of Dodd Boulevard, just east of the Hayes Avenue intersection. The pond was constructed with the roundabout project and will be consolidated with the stormwater ponds in the Summers Creek development. On August 6, 2019, the Dakota County Board approved the conveyance of the easement to the City of Lakeville.

Supporting Information • Staff response to Primary Issues to Consider. • Resolution approving the Summers Creek final plat • Resolution approving the easement vacation • Signed development contract • September 18, 2019 Planning and Engineering Reports (revised September 27, 2019) Financial Impact: $ Budgeted: Y☐ N☐ Source: Related Documents: Zoning & Subdivision Ordinances Envision Lakeville Community Values: A Home for All Ages and Stages of Life Report Completed by: Kris Jenson, Associate Planner October 7, 2019 Staff Response to Primary Issues to Consider • What is the intended purpose of Outlot H? Outlot H will ultimately be platted as a lot for the construction of a detached townhome. In the interim, a temporary connection of Hamburg Avenue to existing Dodd Boulevard will be provided in that location. Platting the future development lot as an outlot now will make it easier for the developer to replat the outlot once the temporary street connection is removed. • Why is a temporary construction easement for future 179th Street required at this time? 179th Street is expected to be constructed in 2022 and temporary construction easements will be required. By obtaining the construction easements now, the City is working with one property owner rather than up to 13 different property owners. The temporary construction easement will expire upon the completion of the street construction project.

EROSION CONTROL. Prior to initiating site grading, the erosion control plan, Plan B, shall be implemented by the Developer and inspected and approved by the City or Dakota County Soil and Water Conservation District. The City may impose additional erosion control requirements if they would be beneficial. All areas disturbed by the grading operations shall be stabilized per the MPCA Stormwater Permit for Construction Activity. Seed shall be in accordance with the City’s current seeding specification which may include temporary seed to provide ground cover as rapidly as possible. All seeded areas shall be fertilized, mulched, and disc anchored as necessary for seed retention. The parties recognize that time is of the essence in controlling erosion. If the Developer does not comply with the MPCA Stormwater Permit for Construction Activity or with the erosion control plan and schedule or supplementary instructions received from the City, the City may take such action as it deems appropriate to control erosion. The City will endeavor to notify the Developer in advance of any proposed action, but failure of the City to do so will not affect the Developer’s and City’s rights or obligations hereunder. If the Developer does not reimburse the City for any cost the City incurred for such work within ten (10) days, the City may draw down the letter of credit to pay any costs. No development, utility or street construction will be allowed and no building permits will be issued unless the plat is in full compliance with the approved erosion control plan. The Developer is responsible for obtaining a MPCA Construction Permit for the site as well as developing a SWPPP for the site prior to construction. The permit requires that all erosion and sediment BMPS be clearly outlined in a site’s SWPPP. Changes made throughout construction should be documented in the SWPPP. Additional erosion control measures may be required during construction as deemed necessary by City staff. Any additional measures required shall be installed and maintained by the Developer. 15. DRAINAGE AND GRADING. The plat shall be graded in accordance with the approved grading development and erosion control plan, Plan “B”. The plan shall conform to City of Lakeville specifications. Within thirty (30) days after completion of the grading and before the City approves individual building permits (except 3 model home permits on lots acceptable to the Building Official), the Developer shall provide the City with an “as constructed” grading plan certified by a registered land 204930v6 7 Summers Creek 204930v6 surveyor or engineer that all storm water treatment/infiltration basins and swales, have been constructed on public easements or land owned by the City. The “as constructed” plan shall include field verified elevations of the following: a) cross sections of storm water treatment/infiltration basins; b) location and elevations along all swales, wetlands, wetland mitigation areas if any, locations and dimensions of borrow areas/stockpiles, and installed “conservation area” posts; and c) lot corner elevations and house pads, and all other items listed in City Code Section 10-3-5.NN. The City will withhold issuance of building permits until the approved certified grading plan is on file with the City and all erosion control measures are in place as determined by the City Engineer. The Developer certifies to the City that all lots with house footings placed on fill have been monitored and constructed to meet or exceed FHA/HUD 79G specifications. The soils observation and testing report, including referenced development phases and lot descriptions, shall be submitted to the Building Official for review prior to the issuance of building permits. Before a building permit is issued, a cash escrow of $1,000.00 per lot shall be furnished to the City to guarantee compliance with the erosion control and grading requirements and the submittal of an as-built certificate of survey. Prior to the release of the required individual lot grading and erosion control security that is submitted with the building permit, an as-built certificate of survey for single family lots must be submitted to verify that the final as-built grades and elevations of the specific lot and all building setbacks are consistent with the approved grading plan for the development, and amendments thereto as approved by the City Engineer, and that all required property monuments are in place. If the final grading, erosion control and as-built survey is not timely completed, the City may enter the lot, perform the work, and apply the cash escrow toward the cost. Upon satisfactory completion of the grading, erosion control and as-built survey, the escrow funds, without interest, less any draw made by the City, shall be returned to the person who deposited the funds with the City. The Developer is coordinating with the VRWJPO to re-meander the existing water quality corridor on the parent parcel. The design will be completed by the Developer and necessary review agencies prior to final plat approval. The stream improvements will occur concurrently with the construction of Summers Creek. The Developer is required to place Natural Area signs along the property lines of 204930v6 8 Summers Creek 204930v6 Outlots C and D. The Developer shall post a security in the amount of $4,500.00 with the final plat to ensure proper installation of signs. Final locations will be identified in the field. The final grading plan shall identify all fill lots in which the building footings will be placed on fill material. The grading specifications shall also indicate that all embankments meet FHA/HUD 79G specifications. The Developer shall certify to the City that all lots with footings placed on fill material are appropriately constructed. Building Permits will not be issued until a soils report and an as-built certified grading plan have been submitted and approved by City staff. Summers Creek contains more than one acre of site disturbance.

SANITARY SEWER. The Developer shall extend public 8-inch sanitary sewer from existing 8-inch sanitary sewer stubs at Hamburg Avenue and Gresford Lane to provide sanitary sewer service to the development. Extension of sanitary sewer through the site will allow for the removal of the temporary lift station located on Lot 1, Block 8, Pine Grove. Removal of the lift station will require extending sanitary sewer across Dodd Boulevard from the Summers Creek subdivision. The sanitary sewer extension and lift station removal shall be completed by the City with the future realignment of 179th Street, anticipated in 2022. The Developer shall design the sanitary sewer to allow for the future removal of the lift station. The Sanitary Sewer Availability Charge has not been collected on the parent parcel and shall be paid by the Developer with the final plat. The fee will be based on the current rate in effect at the time of final plat approval, calculated as follows: 111 units x $327.00 = $36,297.00 Units in Summers Creek Final Plat 2019 Sanitary Sewer Availability Charge Per Unit Sanitary Sewer Availability Charge required 21.

The plat is adjacent to CSAH 9 (Dodd Blvd.) and future Dodd Blvd./179th Street, and is therefore subject to the Dakota County Contiguous Plat Ordinance. The proposed plat includes a revised alignment of future Dodd Blvd/179th Street. The future right-of-way needs for a future 4-lane divided roadway are 75 feet of half right of way. The plat is dedicating 150 feet for future 179th Street West (future County Road). No additional right of way is required along existing CSAH 9 with the plan for a future turnback to the City and vacation of portions of CSAH 9, located west of 175th Street to the new right of way of future Dodd Blvd/179th Street realignment. Current access to the development will be from the south with a temporary access at Hamburg Avenue and existing CSAH 9. Restricted access should be shown along all the future 179th Street, except for Outlot E and the street connections as shown on the plat. As noted, the existing CSAH 23/CSAH 9 intersection will be a restricted access location in the future with the realignment of 179th Street/Dodd Blvd. and turnback of portions of Dodd Blvd. to the City. The Plat Commission has approved the final plat provided that the described conditions are met and will recommend approval to the County Board of Commissioners. A quit claim deed to Dakota County for restricted access is required with the recording of the plat mylars. Traffic volumes on CSAH 9 and Future 79th Street are 16,500 ADT and unknown, respectively, and are anticipated to be 20,000 ADT and unknown by the year 2030. These traffic volumes indicate that current Minnesota noise standards for residential units could be exceeded for the proposed plat. Residential developments along County highways commonly result in noise complaints. In order for noise levels from the highway to meet acceptable levels for adjacent residential units, substantial building setbacks, buffer areas, and other noise mitigation elements should be incorporated into this development. No work shall commence in the County right of way until a permit is obtained from the County Transportation Department and no permit will be issued until the plat has been filed with the County Recorder’s Office. The Plat Commission does not review or approve the actual engineering design of proposed accesses or other improvements to be made in the right of way. Nothing herein is intended to restrict or limit Dakota County’s rights with regards to Dakota County rights of way or property. The Plat Commission highly recommends early contact with the Transportation Department to discuss the permitting process which reviews the design and may require construction of highway improvements, including, but not limited to, turn lanes, drainage features, limitations on intersecting street widths, medians, etc. Please contact Butch McConnell regarding permitting questions at (952) 891-7115 or Todd Tollefson regarding Plat Commission or Plat Ordinance questions at (952) 891-7070.
