17-11-0400 Special (area-specific) landscaping standards.

   In the event that the City Council or Plan Commission adopts plans, designs or guidelines addressing the establishment of area-specific landscaping standards applicable to a designated area of the city or to any specific streets and the area-specific landscaping requirements are inconsistent with the provisions of this chapter or with the provisions of Chapter 10-32 of the Municipal Code, then the area-specific landscaping standards and guidelines govern.

   17-11-0401 Lake Calumet.

      17-11-0401-A Purpose. The Lake Calumet Landscape Area guidelines are intended to:

         1.   act as a guide for developers, design professionals, city staff, and other city departments or public agencies;

         2.   coordinate site development, landscape design, storm water management and environmental issues;

         3.   provide sustainable landscapes for industrial sites that complement the city's Calumet Land Use Plan and Calumet Open Space Reserve Plan.

      17-11-0401-B Boundaries and Descriptions. The boundaries of the Lake Calumet Landscape Area are set forth in the Calumet Design Guidelines adopted by the Chicago Plan Commission on March 11, 2004.

      17-11-0401-C Applicability. All of the following are subject to the guidelines:

         1.   new construction of any principal building or vehicular use area on sites larger than 4 acres;

         2.   new planned developments.

      17-11-0401-D Standards and Methods. The following standards and methods apply within the Lake Calumet Landscape Area.

         1.   Develop industrial sites to mitigate environmental impact through thoughtful design addressing soils, landscape design and management, and stormwater management.

         2.   Provide input and feedback early in the design process between the private and public sector in planning and layout of industrial sites according to the guidelines.

         3.   The lack of available sewers may require 100% of runoff volume to be retained on site.

         4.   Route surface water runoff through stormwater management systems incorporating best management practices (BMPs) improving water quality.

         5.   Reduce site runoff through infiltration techniques and on-site stormwater storage.

         6.   Stabilize riverbanks and shorelines to minimize erosion and sedimentation.

         7.   Minimize fragmentation of open space and increasing BMP efficiency by locating BMPs next to existing open space, natural areas, or stormwater facilities on adjacent lots.

         8.   Integrate BMPs into a sustainable landscape design that minimizes the use of turf grasses.

         9.   Create a natural landscape that blends in with the existing landscape character avoiding linear and repetitive installations of trees and shrubs with an emphasis on native plant species.
