Site Design Category 2 provides standards to ensure compatible site development in areas designated by PlanOlathe as Conservation Neighborhoods. The following site design standards apply to all projects in Site Design Category 2. The letters illustrated in Figure 1 below correspond with the site design standards provided within this section.
A. Common Open Space Options
Development in Site Design Category 2 must provide common open space areas to provide for natural resource protection and recreational opportunities for residents, using at least two (2) of the following methods:
1. Natural Area
A stand of mature trees, shrubs or bushes and/or natural features such as rock outcroppings, hills or other viewpoints.
2. Common Area
A common green space shared by neighboring property owners that may include a lawn, a stand of trees, or shrubs.
3. Natural Drainage Area
Natural streams, lakes, ponds and other drainage areas with indigenous plants, native rocks and other features (note that artificial drainage areas meeting the standards for design of open storm drainage and detention areas may also be used to meet common open space standards).
B. Pedestrian Connection Options
1. Public Sidewalk Connection
A walkway or driveway from a residence that connects directly to a public sidewalk.
3. Internal Path to a Public Sidewalk
A walkway within a development that leads directly to a public sidewalk on the perimeter.
C. Street Connectivity
D. Landscaped Buffer Area
Buffer standards apply to development in Site Design Category 2 when located adjacent to any arterial street or any nonresidential zoning district. Standards are intended to promote a pedestrian-friendly edge to the development and enhance community image. One (1) of the following landscaping strategies must be used within the required minimum setback area on the edges of a residential site adjacent to an arterial street or any nonresidential zoning district. For additional landscaping standards, see Section 18.30.130.
1. Planted Buffer with No Fence or Wall
A landscaped area that is at least ten (10) feet deep with a minimum of seventy (70) percent porous/permeable surfaces and fifty (50) percent planted material.
2. Planted Buffer with a Fence or Wall
A landscaped area that is at least seven (7) feet deep with a minimum of seventy (70) percent porous/permeable surfaces and fifty (50) percent planted material. A fence or wall must be located within the landscape area and include posts, columns, and/or pedestrian gateways a minimum of every one hundred (100) feet (⇔ See Section 18.50.050 for fence height and design).
3. Street-Facing Yard
