(1) Completed City worksheet explaining Better Site Design techniques that were evaluated during project design, the results of the evaluation of each and, for any techniques deemed infeasible. (m) Date of plan preparation and dates of all revisions. (n) A long-term maintenance plan and schedule for all permanent stormwater practices, along with the identity of the party responsible for the maintenance of the project. (o) A snow management plan identifying where and how snow will be stored/removed in order to protect stormwater facilities and BMPs. (4) Stormwater Management Performance Standards. The applicant must meet the following stormwater performance standards. (a) Use of Natural Topography. The applicant shall incorporate the use of natural topography and land cover such as natural swales and depressions as they exist before development to the degree that they can accommodate the additional flow of water without compromising the integrity or quality of the receiving waterbody. (b) Minimize Impact to Natural Features. The development shall minimize impact to significant natural features. Applicant shall review the site for natural features protected under Lino Lakes, State or Federal requirements, including steep slopes, wetlands, wooded areas, endangered or threatened species, or species of concern habitat, areas designated by the County Biological Survey, greenways, parks and open space, groundwater recharge areas, wellhead or surface water protection areas or regional stormwater pond locations. (c) Conveyance System. Wherever possible untreated and treated stormwater runoff shall be conveyed in facilities open to the atmosphere (e.g. swales, vegetated buffer strips, energy -dissipating structures, etc.) rather than through enclosed pipes, so as to decrease runoff velocity, allow for natural infiltration, allow suspended sediment particles to settle, and to remove pollutants. (d) Stormwater Basins. When a stormwater basin is necessary, regional siting is preferred when regional management would not divert supply away from a local recharge area or groundwater -dependent natural resource. In evaluating the appropriateness of peak flow and water quality management in an existing regional basin, the City will consider whether it previously approved the basin and whether the basin was designed for build -out of the site to the extent proposed. (e) Landlocked Basins. A landlocked basin may be provided an outlet only if it:
