(A) As a condition of approval of a final plat and before the City Council approves a final plat, the subdivider shall give satisfactory assurance of the provision of the following requirements:
(1) Monuments. Steel monuments shall be placed at all block corners, angle points, points of curves in roads and at intermediate points as shown on the final plat. All U.S., state, city or other official benchmarks, monuments or triangulation stations in or adjacent to the property shall be preserved in precise position.
(2) Roads. All roads shall be improved in accordance with the road design standards as specified in Appendix III
.
(a) Trees and boulevard sodding shall be planted in conformance with the standards and specifications as required by the City Council.
(b) Street signs of the design approved by City Council shall be installed at each street intersection.
(c) Driveway approaches and sidewalks of a standard design or pedestrian pathways as may be required by the City Council shall be installed.
(d) Street lighting fixtures as may be required by the City Council shall be installed.
(3) Water supply. Wherever connection with a community or public water system is possible, the public water shall be used. In other case, individual wells shall be used. Either shall be provided in accordance with state and city regulations.
(4) Sanitary sewer. Wherever trunk line sanitary sewer facilities are available, the subdivider shall be required to install sanitary sewers and connect the same to such trunk line sewers. In other cases, individual on-site sewage treatment systems shall be used. Either shall be provided in accordance with state and city regulations.
(5) Stormwater management.
(a) When possible, existing natural drainageways, wetlands and vegetated soil surfaces must be used to convey, store, filter and retain stormwater runoff before discharge to public waters.
(b) Development must be planned and conducted in a manner that will minimize the extent of disturbed areas, runoff velocities, erosion potential and reduce and delay runoff volumes. Disturbed areas must be stabilized and protected as soon as possible and facilities or methods used to retain sediment on the site.
(c) When development density, topographic features, and soil runoff using natural features, and vegetation, various types of constructed facilities such as diversions, settling basins, skimming devices, dikes, waterways and ponds may be used. Preference must be given to designs using surface drainage, vegetation and infiltration rather than buried pipes and man-made materials and facilities.
(6) Landscaping. All developments shall be landscaped with a combination of overstory trees, understory trees, shrubs, flowers and ground cover materials. All areas not covered by buildings, streets, sidewalks, parking lots, driveways or similar hard surface materials shall be covered with sod or an equivalent ground cover approved by the city. This requirement shall not apply to site areas retained in a natural state. All new landscape trees and shrubs must meet the American Standard for Nursery Stock and American National Standard relating to planting guidelines, quality of stock and appropriate sizing of the root ball. Landscape trees must be balled and burlapped or moved from the growing site by tree spade. Deciduous trees will be not less than one and one quarter inches but not more than three inches caliper for balled and burlapped trees, and not less than three inches but not more than six inches caliper for spade-moved trees. Coniferous trees will not be less than six feet in height but no more than eight feet for balled and burlapped trees, and not less than eight feet in height but not more than fourteen feet for spade-moved coniferous trees. The city may allow larger balled and burlapped or spade moved trees if these trees are accompanied with a three year guarantee.
(7) Erosion and sediment control. The development shall conform to the natural limitations presented by topography and soil so as to create the least potential for soil erosion. If determined necessary by the City Engineer, the subdivider shall be required to submit an erosion and sediment control plan. Erosion and sediment control measures shall be consistent with best management practices (BMPs) for erosion and sedimentation control as specified in the "Minnesota Stormwater Manual" (MPCA, 2005), as amended, and shall be sufficient to retain sediment on site. Erosion and sediment controls shall meet the standards for the general permit authorization to discharge stormwater associated with construction activity under the national pollutant discharge elimination system/state disposal system permit program permit MN Rl00001 (NPDES general construction permit) issued by the Minnesota Pollution Control Agency, as amended. Final stabilization of the site must be completed in accordance with the NPDES construction permit requirements.
(B) All required improvements shall be installed by the subdivider except that the city reserves the right to elect to install all or part of the improvements required under the provisions of this title pursuant to M.S. Ch 429, as it may be amended from time to time. If the city elects to install the improvements the city may require the developer to post a cash escrow or letter of credit guaranteeing payment of the assessments.
(C) Satisfactory assurance that all required improvements shall be provided shall include:
(1) Entering into a development contract setting forth the conditions under which the plat is approved and setting forth required improvements.
(2) Furnishing the city financial security in the form of a cash escrow or letter of credit. Letters of credit must be from a state or federally chartered bank or savings and loan association, insured by the Federal Deposit Insurance Corporation, that has an office in the state of Minnesota or a subsidiary of such bank or savings association with an office in the state of Minnesota. If the subdivider fails to perform any obligations under the development contract, the city may apply the security to cure the default.
(a) If the subdivider is going to install the public improvements, the required security shall be the sum of the following fixed or estimated costs:
1. Utilities.
2. Streets.
3. Streetlights and operating cost for one year (if any are required).
4. Erosion control.
5. Engineering, to include developer's design, surveying and inspection.
6. Landscaping (if any is required).
7. Storm sewer connection charges.
8. Principal amount of special assessments previously levied against the property together with one year of interest.
9. Real estate tax for one year, if there are special assessments.
10. City engineering fees.
11. Sanitary sewer area charges (if any are required).
12. Lateral sanitary sewer and water main access charges.
13. Wetland mitigation (if any is required).
14. Custom graded lots (if any is required).
15. Removal of buildings and temporary improvements (if any is required).
16. Tree preservation.
17. Lot corners/iron monuments.
(b) If the city is going to install the public improvements, the required security shall be the sum of the following fixed or estimated costs:
1. Principal amount of special assessments for public improvements to be installed together with one year of interest.
2. Streetlights (if any are required).
3. Erosion control.
4. Landscaping.
5. Storm sewer connection charges.
6. Real estate tax for one year.
7. Principal amount of special assessments previously levied against the property together with one year of interest.
(3) The city shall require of a subdivider submission of a warranty/maintenance bond in the amount equal to the original cost of the improvements or such lesser amount as agreed to by the City Engineer. The required warranty period for materials and workmanship from the utility contractor installing public sewer and water mains shall be two years from the date of final acceptance or one year following final acceptance of the final bituminous wearing surface as approved by the City Engineer. The required period for sod, trees and landscaping is one growing season.
(D) No final plat shall be approved by the Council without first receiving a report from the City Engineer that the improvements described therein together with the agreements and documents required under this section, meet the requirements of the city.
(E) No final plat shall be approved by the Council without first receiving certification from the City Clerk, Administrator or Finance Officer that all fees required to be paid to the city in connection with the plat have been paid or that satisfactory arrangements have been made for payment.
