      9.   Existing and proposed easements on the property.
      10.   Location of existing and proposed curb, gutter and sidewalk on the adjacent city street (sidewalk may or may not be required). If new curb and gutter is to be installed, a profile of the TBC must be shown. Also, elevations on the existing edge of asphalt must be shown every fifty feet (50') if the street grade is greater than one percent (1%), and every twenty five feet (25') if the street grade is less than one percent (1%). Also, a cross section of the street widening showing pavement thicknesses must be shown.
      11.   Any off site improvements, including, but not limited to, acceleration and deceleration lanes, utility extensions, storm drainage facilities or other off site systems that are impacted by the proposed site plan.

   C.   Grading, Drainage Plan: Grading and drainage plan, including the following:
      1.   Existing and proposed topographic contour lines at intervals that clearly identify the topographic layout of the land on the property, but in no case shall the contours be at an interval greater than two feet (2').
      2.   Spot elevations must be shown of the final floor elevation of all structures, flow lines of all pipes, strategic locations of existing and proposed TBC, top of storm drain grates and at other locations as deemed necessary by city staff.
      3.   Hydrology calculations based on a 10-year storm. The calculation must size the detention basin, size the orifice plate and determine the amount of flow which can be released (the release rate can be 0.2 cfs/acre). Detention basin shall retain the required 24-hour storm equivalent, as required under the Utah pollutant discharge elimination system (UPDES) general discharge permit.
      4.   A table itemizing the amount and percentage of area considered, impervious (buildings, pavement, etc.) and pervious surfaces (landscaping and natural areas).
      5.   Location of the overflow spillway, including spot elevations as needed.
      6.   Location and shape of water surface at the detained 10-year storm level, including the elevation.
      7.   Location of roof drains, including where they will tie into the storm drain system.
      8.   Stormwater pollution prevention plan (SWPPP), when required.
      9.   Low impact development (LID):
         a.   Low impact development (LID) is an approach to land development that uses various land planning and design practices and technologies to simultaneously conserve and protect natural resource systems and reduce infrastructure costs. LID still allows land to be developed, but in a cost effective manner that helps mitigate potential environmental impacts.
         b.   As part of the city of North Salt Lake permit, the city requires use of an LID approach, which includes the implementation of structural BMPs, where practicable, that infiltrate, evapotranspire or harvest and use stormwater for the site to protect water quality.
         c.   All development and redevelopment that warrants compliance with the UGCP regulation must include an LID analysis that meets the objective of mirroring the predevelopment hydrology and meets the objective of retaining on site, with no discharge, the 0.6-inch, 24-hour rainfall event.
         d.   Redevelopment of commercial, industrial, institutional, or multi-family sites that add or replace (alone or in combinations) five thousand (5,000) square feet of impervious surface or disturb five thousand (5,000) square feet of land must include an LID analysis that meets the objective of retaining on site, with no discharge, the 0.6-inch, 24-hour rainfall event. Groundwater recharge may be considered to meet this requirement, where applicable and feasible.
         e.   No LID limits are defined except designs must not negatively impact surrounding properties. The analysis must identify LID options considered and list the reasons why it will be incorporated or why the considered LIDs are not practical for the site use or conditions. Submit a report with stormwater calculations that summarizes the analysis and results.
         f.   Suggested and preferred LIDs are outlined in the city's "Stormwater Best Management Practices Handbook". The city engineer may consider and approve other innovative LID approaches not included as preferred measures that meet or exceed the objectives of the city's stormwater management plan.
      10.   Postconstruction stormwater maintenance plan and agreement:
         a.   The purpose of the postconstruction stormwater maintenance plan and agreement is to control stormwater runoff and reduce pollutants in stormwater runoff after construction is complete and the developed site is in operation. This is achieved by accomplishing the following:
            (1)   Controlling erosion.
            (2)   Controlling discharge of sediment into stormwater drainage facilities or off site.
            (3)   Preventing illicit discharges into on site soils, storm drainage facilities or off site.
            (4)   Prevention of debris and garbage from entering the stormwater system.
         b.   A postconstruction stormwater maintenance plan must be prepared and submitted with the plans for approval for all privately owned or maintained facilities that warrant compliance with the UGCP regulation. The plan shall be contained on a plan sheet of its own, rather than being a part of another plan sheet, and is to contain at least the following:
            (1)   The site plan, including vicinity map, proposed contours, permanent stormwater features, and landscaping.
            (2)   BMPs to accomplish the purpose of the plan. Examples of appropriate BMPs may include those addressing operation and maintenance of storm drainage quality control facilities, operation and maintenance of stormwater discharge control facilities, maintenance of landscaping, good housekeeping practices, etc.
            (3)   Showing the following for each BMP specified:
               (A)   Location and extent of specified BMPs, as appropriate.
               (B)   Detailed schedule of execution for each specified BMP, in terms of starting time, duration, frequency, etc., as appropriate.
               (C)   Any information in addition to or different from that shown on the BMP fact sheets as necessary to employ the BMPs on the site.
         c.   The owner of development that warrants compliance with the UGCP regulation must submit a signed stormwater maintenance agreement using the city of North Salt Lake agreement template. The postconstruction maintenance agreement needs to be recorded at the Davis County recorder's office.
   D.   Landscape Plan: Landscape plan, prepared by a licensed architect or landscape architect, showing the following:
      1.   Location and type of all landscaping. Show locations, type and size of all trees.
      2.   The total area in square feet of all landscaping.
      3.   Location of irrigation system, including heads.
      4.   All landscaping shall conform to Title 10, Chapter 22, Water Efficient Landscape Standards.
   E.   Building Plan: Building plan, showing the following:
      1.   Elevation view from front, side and rear.
      2.   Height of building.
      3.   Type of exterior construction.
   F.   Miscellaneous: The following may be required depending on field conditions, type of business, etc.:
      1.   Erosion control plan.
      2.   Retaining wall details.
      3.   Density calculations (to be provided for multi-family dwellings, condos, etc.).
      4.   Screening of yards.
      5.   Davis County flood control approval (to be provided when drainage ties into Davis County storm drain system).
      6.   Agreements with railroad companies, petroleum carrier companies, adjacent landowners, etc. (Ord. 2011-07, 5-3-2011; amd. Ord. 2014-16, 10-21-2014; Ord. 2016-12, 8-16-2016; Ord. 2022-03, 6-7-2022)
