If a proposed subdivision is indirectly tributary to a Category I, II or III waterbody and intervening regional detention storage is inadequate, in the opinion of City staff, to meet the water quality goals for .downstream Waterbodies as .described in the SWMP, additional on-site pond construction will be required to meet these goals.. d. If a proposed subdivision. will increase rates. of runoff and where downstream storm water storage or conveyance facilities are inadequate to .protect downstream riparian owners. from effects of these increases, then on-site storm .water storage must be constructed to restrict storm water rates to the pre-development rates. 9. Where on-site water quality detention basins are required, copies of the calculations determining the design of the basins. The size and design considerations will be dependent on .the receiving waterbody's water .quality category, the imperviousness of the development and the. degree to which on-site infiltration of runoff is encouraged. Design of on-site detention basins, as described in the site's runoff water management plan, shall incorporate recommendations from. the Nationwide Urban Runoff Program (NURP) and "Protecting Water Quality in Urban Areas", published by the Minnesota Pollution Control Agency,. as adopted by the City, or the applicable publications, as adopted by the City. The following design considerations are required for on-site water quality detention basins based on the receiving water's water. quality category.. These designs include permanent detention for water quality treatment; extended detention designs may be substituted provided that they provide treatment equivalent to the requirements below: a. Basins Tributary To Category I Waterbodies: (1) A permanent pool (dead storage) volume below the normal outlet shall be greater than or equal to the runoff from a two and one-half (2.5) .inch twenty four (24) hour storm over the entire contributing drainage area assuming full development. (2) A permanent pool average depth (basin volume/basin area) which shall be greater than four (4) feet, with a maximum depth of less 37 than ten (10) feet. (3) An emergency spillway (emergency outlet) adequate to control the one hundred (100) year frequency critical duration rainfall event. (4) Basin side :slopes above the normal water level should. be no steeper than three. to one (3:1) when possible, and preferably flatter. A basin shelf with a minimum width of ten (10) feet and a maximum slope of ten to one (10:1) below the normal water level is recommended to enhance wildlife habitat, reduce potential. safety hazards, and improve access for long-term maintenance. (5) To prevent short-circuiting, the distance between the major inlets and normal outlet shall be maximized. (6) A flood pool (temporary storage) volume above the principal outlet spillway shall be adequate so that the peak discharge rate from the ten (10) and one hundred (100) year frequency .critical duration storm is not greater than the peak discharge for a similar storm and pre-development watershed conditions. (7) Extended detention of runoff from the more frequent (1-year to 5- year) storms shall be achieved through a principal spillway design which shall include a perforated vertical riser, a small. orifice outlet or a compound weir. (8) Effective. energy dissipation devices which reduce outlet velocities to four (4) feet per second or less shall consist of rip rap, stilling pools or other such measures to prevent erosion at all storm water outfalls into the basin and at the detention basin outlet. (9) Trash and floatable debris skimming devices shall be placed on the outlet of all on-site detention basins to provide treatment up to the critical duration ten (10) year .storm event. These devices can consist of baffled weirs, submerged inlets or other such measures capable of restricting the overflow of floatable materials, including litter, oil and grease. Computations for the design of such devices shall be included. (10) For purposes of erosion control, vegetation protection and wildlife habitat enhancement,. the ten (10) year flood. level of the basin shall be no more than two (2) feet above the normal level of the basin. b. Basins. constructed adjacent or tributary by surface or subsurface discharge to a Category Ia waterbody shall also meet the following design standards: 38 (1) Infiltration 'areas are required for newly platted areas .with volume sufficient to contain one and one-half (1.5) inch of runoff .from all impervious surfaces, 'including rooftops, for existing and future phases of development; _ and have .average depth such that this volume. infiltrates within seventy-two (72) hours. The. infiltration rate can be determined via direct measurement with a soil percolation test, other permeability test, or by estimation using the conservative end of the range given in the Dakota County Soil Survey for the soil. type as mapped there at the discretion of the City Engineer. (2) Where soil permeability. does not meet. the above criteria, additional design considerations to enhance the rate of pond seepage such as a drain the outlet ar other measures may be required by the City Engineer. (3) Infiltration depressions shall not be lined nor shall mining of native material be allowed. (4) Re-vegetation on the. infiltration area bottoms shall consist in the majority of plant types which can tolerate inundated condition for periods of days and have root depths in excess of eighteen (18) inches. (5) The lowest topographical point in an infiltration depression should be at least two (2) .feet above the average water table in that location. (6) Ponding areas-shall be set back a distance of seventy-five (75) feet from the stream centerline to the edge of a pond. In the case of distributed infiltration areas, this setback. may be varied. Where the stormwater design is such. that fifty (50) percent of the infiltration area volume is beyond one hundred (100) feet from the channel centerline,. no setback is required. (7) Effective energy dissipation devices which reduce outlet velocities to four (4) feet per. second or less shall consist or rip rap, stilling pools or .other such .measures to prevent erosion at all storm water outfalls into the basin and at the detention basin outlet. c. Basins Tributary To Category II Waterbodies: (1) A permanent pool (dead storage) volume below the .normal outlet shall be greater .than or equal to the runoff from a two (2) inch twenty four (24) hour storm over the entire contributing .drainage area assuming full development, 39 (2) All other requirements as listed in subsections 10-4-6B9a2 through 10 for Category I and Ia waterbodies. d. Basins Tributary To Category III Waterbodies: (1) A permanent pool (dead storage) volume below the normal outlet shall be greater than or equal to the runoff from a one and one-half (1.5) inch twenty four (24) hour stormover the entire contributing drainage area assuming full development. (2) All other requirements as listed in subsections 10-4-6B9a2 through l0 for Category I and Ia waterbodies. e. Basins Tributary To Category IV Waterbodies: (1) Any practical measures needed to maintain the .function and character of the Category IV waterbody. f. Basins Tributary To Wetlands: (1) Sedimentation capacity. capable of protecting the wetland from filling due to water borne. silts and sand. Where. feasible, appropriately sized sump manholes or other in-line treatment capable of being cleaned via manholes shall be preferred. (2) All other requirements as listed in subsections 10-4-6B9a2 through 10 for Category I waterbodies. 10-4-7: PROTECTED AREAS: Where land proposed for subdivision is deemed environmentally sensitive by the City due to the existence of wetlands, drainageways, watercourses, floodable areas, significant trees, steep slopes or wooded areas or its proximity to Category Ia waterbodies, the design of said subdivision shall clearly reflect all necessary measures of protection to ensure .against adverse environmental impacts. Based upon the necessity to control and maintain certain sensitive areas, the City shall..determine whether said protection will be accomplished through lot enlargement and redesign or dedication of those sensitive areas in the form of outlots. In general, measures of protection shall include design solutions that allow for construction and grading involving a minimum of alteration. to sensitive areas. Such measures, when deemed appropriate by the City, may include, but shall not be limited to, the following:. 40 A. -The establishment of buffers designed consistent .with adopted management plans, easements and/or outlots over wetlands, drainageways and watercourses.- B. The implementation of flood control measures, including ponding and infiltration design standards as specified in adopted management plans. C. The enlargement of lots or redesign of the subdivision. D. The submission of a tree preservation plan subject to the review of the Environmental Affairs Committee and the approval of the City Council. E. The utilization of appropriate erosion control measures subject to approval by the City Engineer. F. Soil testing to determine the ability of the proposed subdivision to support development. G. The limitation of development on slopes steeper than three to one (3:1). H. Structure conformance to the .natural limitations presented by the topography and soil so as to create the least potential of soil erosion. 10-4-8: DEDICATION REQUIREMENTS: A. As a condition of subdivision approval, subdividers shall dedicate a portion of any proposed subdivision for conservation purposes or for public use as parks, recreational facilities as defined and outlined in Minnesota Statutes section 471.191, playgrounds, trails, wetlands, or open space; provided that the City may choose to accept an equivalent amount in cash for part or all of the portion required to be dedicated based on the fair market value of the land at the time of final approval. B. Land shall be reasonably suitable for its intended use and shall be at a location convenient to the people to be served. Factors used in evaluating the adequacy of proposed park and recreation areas shall include aize, shape, topography, geology, hydrology, tree cover, access and location. Land with trash, junk, pollutants and unwanted structures is not acceptable. C. The Park and Recreation Advisory Committee shall recommend to the City Council the land and/or cash contribution requirements for proposed subdivisions. D. Any increase in density of subdivisions shall be reviewed by the Parks and Recreation Committee for reconsideration of park land and/or cash contribution requirements. E. When a proposed park, playground, recreation area or other public ground has been indicated in the City's Official Map or Comprehensive Plan and is located in whole or in part within a proposed subdivision, it shall be designated as such on the plat and shall be 41 conveyed to the City. If the subdivider elects not to dedicate an area in excess of the land required hereunder for such proposed public site, the City may consider acquiring the site through purchase or condemnation. F. Land area conveyed or dedicated to the City shall not be used in calculating density requirements of the City Zoning Ordinance) and shall be in addition to and not in .lieu of open space requirements for planned unit developments. G. Where private open space for park .and recreation purposes is provided in a proposed subdivision, such areas may be used for credit, at the discretion of the City Council, against the land or cash dedication requirement for park and recreation purposes, provided. the City Council finds it is in the public interest to do so. H. The dedication requirements are presumptively appropriate. A subdivider .may request a deviation from the presumptive requirements based upon the anticipated impact of that particular subdivision. The request must be made before final subdivision approval by the City. I. In residential subdivisions where a land dedication is required, the following formula will be used to determine the dedication requirement: Density Units Per Acre Land Dedication Percentage 0 - 2.5- 10% 2.5 - 4 11% 4+ - 6 13% 6+ - 8 15% 8+ - 10 17% 10+ 17%-20% In commercial. or industrial subdivisions where a land dedication is required the following formula will. be used to determine the dedication: five (5) percent of the gross area of land being platted. J. In lieu of land dedication the City may require the following cash. contribution: Commercial/industrial 5% of current market value of the unimproved land as determined by the County Assessor Multi-family dwelling units $1,500.00 per dwelling unit Single-family dwelling units $1,500.00 per dwelling unit 1. See Title 11 of this Code. 42 K. The City may elect to receive a .combination of cash, land and development of the land. The fair market value of the land the City wants and the value of the development of the land shall be calculated. That amount shall be subtracted from the cash contribution required by subsection J of this Section. The remainder shall be the cash contribution requirement. L. "Fair market value" shall be determined as of the time of final subdivision approval in accordance with the following: 1. The City and the developer may agree as to the fair market value, or 2. The fair market value may be based upon a current appraisal submitted to the City by the subdivider at the. subdivider's expense. The appraisal shall be made by appraisers who are approved members of the SREA or MAI, or equivalent real estate: appraisal. societies. 3. If the City disputes such appraisal the City may, at the subdivider's expense, obtain an appraisal of the property by a qualified real estate appraiser, which appraisal shall be conclusive evidence of the fair market value of the land. M. Planned developments with mixed land uses .shall make. cash and/or land contributions in accordance with-this Section based upon the percentage of land devoted to the various uses. N. Cash contributions are to be calculated at the time of final subdivision approval. The Council may require the payment at the time of final subdivision approval or at a later time under terms agreed upon in the development agreement. Delayed payment shall include interest at a rate set by the City. Q. Cash contributions shall be deposited in the Park Dedication Fund and shall only be used for the acquisition of land for the purposes set forth in subsection A of this Section, and the planning and development of land for such purposes. R. Property being subdivided without an increase in the number of lots shall be exempt from park and trail dedication requirements if similar requirements were satisfied in conjunction with an earlier subdivision. If the number of lots is increased, then the dedication shall be based on the additional lots created. 10-4-9: MINIMUM DESIGN FEATURES: The design features set forth in this Chapter are minimum requirements. The City may impose additional or more stringent requirements concerning lot size, streets and overall design as deemed appropriate considering the property being subdivided. 43 10-4-10: ZONING ORDINANCE CONSISTENCY: Subdivisions and preliminary and final plats may only be approved if they are consistent with the City's Zoning Ordinance. 10-4-1 L TREE PRESERVATION: The following process for preserving significant trees shall be required of subdividers and homebuilders.
