(A) Erosion and sediment control standards shall comply with the city’s engineering design guidelines (“Design Manual”) as well as Chapter 4 of the city’s zoning ordinance.
(B) The development shall conform to the natural limitations presented by topography and soil so as to create the least potential for soil erosion.
(C) Erosion and siltation control measures shall be coordinated with the different stages of construction. Appropriate control measures shall be installed prior to development when necessary to control erosion.
(D) Land shall be developed in increments of workable size such that adequate erosion and siltation controls can be provided as construction progresses. The smallest practical area of land shall be exposed at any one period of time.
(E) When soil is exposed, the exposure shall be for the shortest feasible period of time.
(F) In the event that permanent stabilization cannot be feasibly obtained within 14 days after construction activity in that portion of the site has temporarily or permanently ceased, and seven days if discharge points are located within one mile of an impaired or special water body, temporary soil stabilization BMPs must be implemented within the time frame.
(G) Where the topsoil is removed, sufficient arable soil shall be set aside for respreading over the developed area. The soil shall be restored to a depth of four inches and shall be of a quality at least equal to the soil quality prior to development.
Subdivision design shall be consistent with limitations presented by steep slopes. Subdivisions shall be designed so that no construction or grading will be conducted on slopes steeper than 3:1 in grade, unless otherwise approved by the City Engineer based on exiting topographic conditions.
(A) Where the subdivision of a lot or tract of land contains drainageways, watercourses floodable areas, or wetlands, and thus may be unsuitable for development, the areas shall be handled as follows.
(2) If the land is not designated for public use on an official plan, then the developer shall cause the land to be carried in a private easement in the individual deeds affected thereby, and no permit shall be issued for a building permit.
(B) The developer may submit a proposal for development indicating how, through site and engineering design, the intent of this chapter will not be violated if approved. In addition, the developer shall provide a surety bond to the approving city to ensure that such will be done at a specific time if approved.
(C) Any development or platting shall comply with the city’s zoning ordinance and/or county shoreland regulations.
(A) (1) Every subdivision shall include a landscape plan that identifies areas of public value, including significant views, natural vegetation, or watercourses, even where the features may be located upon private lots.
(2) The landscape plan shall provide for the addition of trees, shrubs, and ground covers or grasses that achieve the following objectives:
(a) Establish naturalized woodland areas in large spaces;
(b) Establish naturalized areas around stormwater ponds; and/or
(c) Establish naturalized woodland areas at the edges of subdivisions, particularly in areas of land use changes or where the subdivision abuts a major roadway, utility line, or railroad.
(B) The landscaping plan shall be accompanied by a reliable estimate of installation costs. The subdivider shall provide a financial security that guarantees live growth of the plant materials for one complete year or two growing seasons from the date of installation. In the event the plant materials under this plan must be replaced due to death, disease, or other reason, the financial security shall be extended to cover an additional two years from the date of replacement.
