Gardner City Zoning Code
CHAPTER 17
08 SITE AND LANDSCAPE STANDARDS
§ 17.08.010 INTENT AND APPLICABILITY.
A.
Intent. The intent of this section is to:
1.
Create an attractive aesthetic environment in the City, and preserve the value of adjacent properties as development and redevelopment occurs.
2.
Make more efficient and effective investment in site designs by coordinating open space design across various adjacent development sites, and use buffers and separations when other designs will not maintain compatibility with adjacent sites.
3.
Value the design, function, and perceptual impact of open space, rather than simply quantity of open space.
4.
Develop different measurements for specific types of formal and natural open space to apply in specific contexts, and ensure that open space is not merely left over or underutilized space.
5.
Encourage efficient site design where the layout of sites and buildings can meet multiple requirements and allow open space to serve multiple aesthetic or screening, environmental, and recreational functions.
6.
Promote strong and well-designed relationships between development and the public realm.
7.
Enhance the environmental and ecological function of unbuilt portions of sites.
8.
Reduce the exposure and adverse impacts of intense land uses, activities and site elements on streets and adjacent areas, and mitigate the effects through landscape designs.
B.
Applicability. A landscape plan is required in association with a site plan, according to the application requirements in Chapter 17.03 GMC. Specifically it is required for:
1.
New uses and buildings in any zoning district except detached dwellings, duplexes or townhouse residences;
2.
Any addition to an existing building, structure or site where site grading occurs, but the requirements of this section shall be prorated to that portion of the site affected by development;
3.
All elements of an approved landscape plan, including plant materials, shall be considered elements of the project in the same manner as parking, buildings or other details. The applicant and future successors or owners are responsible for the continued maintenance of these features and failure to maintain these features is a violation of the terms of approvals or subsequent permits.
Site and landscape standards may be specifically modified through the planned zoning process in Chapter 17.03 GMC.
(Ord. 2518 § 2 (LDC § 8.01))
§ 17.08.020 OPEN SPACE DESIGN.
All lots shall have access to Open and Civic Space Systems as provided in GMC § 17.04.020. Where such spaces are not existing, or are not provided through platting of development plans, additional open spaces should be incorporated into site plans to best meet the intent of this chapter.
(Ord. 2518 § 2 (LDC § 8.02))
§ 17.08.030 LANDSCAPE DESIGN.
A.
Planting Requirements. Landscape materials shall be provided and maintained according to the following:
Table 8-1: Landscape Requirements | ||
|---|---|---|
Residential Districts | Nonresidential Districts | |
Frontage | See GMC § 17.07.050, Frontage Design, for specific planting specifications for different Frontage Types; and see Chapter 17.04 GMC for streetscape planting requirements. | |
Foundation Planting | None required | Except for buildings permitted within 10' of ROW, foundation planting areas shall exist along at least 25% of street facing facades and be at least 8' deep. 1 small tree for every 40 linear feet of foundation. 1 shrub for every 10 linear feet of foundation. |
Parking Areas | 1 large or medium tree for each 40 spaces. 1 shrub for every 5 linear feet of perimeter buffer along frontage/street side. 1 large or medium tree for every 50 linear feet of perimeter buffer. 50% reduction if designed with 2.5' - 4' decorative wall or fence complementing the architecture and materials of the building along the street side. | 1 large or medium tree for each 40 spaces. 1 shrub for every 5 linear feet of perimeter buffer along frontage/street side. 1 large or medium tree for every 30 linear feet of perimeter buffer. 50% reduction if designed with 2.5' - 4' decorative wall or fence complementing the architecture and materials of the building along the street side. |
Buffers | See Table 8-2. | |
Civic or Open Space | See GMC § 17.04.020 and design specifications for Civic and Open Space Systems where applicable. | |
Other Open Areas Generally | 1 tree per 10,000 s.f. 1 shrub per 5,000 s.f. All other permeable surfaces in the open space and landscape plan shall include ground cover to prevent dust and soil erosion, with turf, native grass or shrub areas. | |
In general, species for meeting the landscape requirements shall be based on the Great Trees for the Kansas City Region incorporated as an Appendix C[1] to this Code. Although Appendix C does not offer a list of medium trees, it should be understood that trees expected to mature to a range of30 - 50feet in height and 30 - 50feet spread based on anticipated growth patterns and planting context can be considered as medium trees. Examples may include Quercus lyrata (Overcup Oak), Ostrya virginiana (Hophornbeam) and Koelreuteria paniculata (Golden Raintree). | ||

Editor's Note: Appendix C Great Trees for the Kansas City Region is included as an attachment to this title.
B.
Buffer Planting. The following planting requirements shall be located along the perimeter of sites to buffer more intense uses and to design effective transitions. The buffer width exists independent of and may include any setback, parking perimeter buffer or other open space requirement. The plant requirement is in addition to any other required plants.
