§ 4-11 REQUIRED LANDSCAPING FOR ALL COMMERCIAL, MULTI-FAMILY RESIDENTIAL AND INDUSTRIAL PROPERTY.
   (A)   Purpose, objectives and procedure.
      (1)   Purpose.
         (a)   The purpose of this section is to establish a uniform procedure for the review of plans for the development of commercial, multi-family residential and industrial property located within the city limits. This procedure includes a comprehensive review by the Planning Department to assure that city codes and standards will be met and the objectives of this section are specifically addressed.
         (b)   This section is a required part of the building permit application process. It is hereby found that the establishment of this procedure will work toward assuring development which complies with the objectives of this section and enhances area architectural and environmental elements in furtherance of the best interest of this community. Furthermore, developers are encouraged to design developments which harmonize with the existing terrain, rather than changing the site to fit a specific design.
      (2)   Objectives. The Site Plan Review process shall reach a determination that the following objectives have been met:
         (a)   Proposed projects shall respect the natural, wooded environment to preserve, protect and incorporate this natural environment into the overall Site Plan design;
         (b)   The Site Plan shall be examined to assure that all provisions of this section and all other applicable city standards are complied with or where a greater standard is required, those standards shall prevail;
         (c)   Ingress, egress, internal traffic circulation, off-street parking facilities, loading and service areas and pedestrian ways shall be designed to promote safe, efficient vehicular circulation, pedestrian movement, parking and site serviceability; and
         (d)   When commercial, multi-family residential or industrial uses are proposed next to existing less intensive uses, the Site Plan Review process shall emphasize quality project design, aesthetics and landscaping designed to minimize the impact of the project on the established area and/or establish transitional areas to meet the objectives of the Site Plan Review Standards.
      (3)   Procedure.  
         (a)   The review procedure for each Site Plan application shall begin with a comprehensive review by the Planning Department.
         (b)   Staff shall review the plans to determine code compliance and compliance with the objectives. All plans shall be corrected to comply with all minimum codes and adopted policies. Staff shall determine if codes have been met and how the objectives have been addressed.
   (B)   Applicability.
      (1)   For all new commercial, multi-family residential and industrial property within the city limits, and remodeled commercial, multi-family residential and industrial property where improvements of at least a 20% increase in square footage are added.
      (2)   Zoning districts affected are C-1, C-2, C-3, CBD, R-2, R-4, R-5, R-6, I-1, I-2. R-2 exception: single family dwellings and garage apartments.
   (C)   Submittal requirements. The Site Plan shall comply with this section and applicable sections of this code, and shall contain the following:
      (1)   Disclosure of the boundaries of the property and building site and location of all utilities and easements of record;

      (1)   Purpose. The Site Plan shall be reviewed to assure that all proposals present a landscaped appearance that is site sensitive and enhances and preserves the existing vegetation, and is in harmony with surrounding development and the natural environment. The landscape plan, material, berms, fences and walls should be utilized to:
         (a)   Preserve and utilize the existing natural features, existing vegetation and other physical site values where possible;
         (b)   Provide screening/buffering or undesirable views;
         (c)   Soften the visual impact of paved areas;
         (d)   Soften the edge between a parking lot or street and the building;
         (e)   Define walkways, traffic circulation, special use areas and building entries;
         (f)   Complement the architectural form of the building;
         (g)   Mitigate the impacts of lighting or other negative influences;
         (h)   Provide a pleasant driving experience;
         (i)   Provide shade for the landscape, building and parking lot;
         (j)   Provide for energy conservation;

      (2)   Percent of landscaping required to meet the objectives of Site Plan Review.
         (a)   No less than 10% of the net lot area shall be landscaped unless greater landscaping standards apply based on the requirement of another zoning category, or the incentive standards have been met for reduction of the 10% landscaping. Fifty percent of the total landscaping shall be along the frontage. Right-of-way is not to be included. For industrial projects with no sensitive borders or frontage on major arterial roadways, the minimum landscaping could be reduced to 5% at the discretion of the City Manager or his designee. These are requirements of the Site Plan process, including the Planning Commission process.
         (b)   An eight-foot sight-proof fence is required between residential and commercial or industrial properties.
      (3)   Landscaping standards. All applicable uses within the city limits shall be landscaped with trees and ornamental shrubs according to the following standards.
      (4)   Application for Site Plan approval shall be accompanied by a detailed landscaping plan for the required lot area. The plan shall meet the following requirements:
         (a)   Submit a detailed plan listing that identifies the types of plant material proposed and existing vegetation to be preserved.
         (b)   Include on the Site Plan a summary of the landscape area calculations and total plan unit values proposed.
         (c)   There shall be a minimum of 20 live plant units provided for every 250 square feet of area required to be landscaped. A minimum of 40% shall be evergreens. Fifty percent of required plantings should be located on the front elevation.

The percent of landscaped area required by this section may be reduced for each of the following conditions that are met or exceeded. The percent of landscaped area required may not be reduced by more than three full percentage points. The amount of percentage points specified for each of the following conditions shall apply.
         (a)   Thirty-five percent of the required plant units consist of existing trees proposed for preservation. These trees will require city staff review and approval to determine the variety, size, quality, potential for long-term survival and plant unit value. Any trees that will have their root systems disturbed in any way within the area covered by their canopy will not be considered. A maximum of 1-1/2 percentage points will be allowed.
         (b)   If the height of signs is decreased by 50%, the percent of landscaped area required by ordinance may be reduced by 1%. If the height of the sign is reduced by 25%, the percent of landscaped area required by ordinance may be reduced by one-half percent.
