A. The suggested amount of recreational open space in a proposed development generally should be five hundred (500) square feet per proposed detached single-family home and three hundred (300) square feet per proposed multi-family unit. The multi-family dwelling unit rate applies to any residential dwelling unit other than detached single-family dwellings. When a plat is requested for mixed land uses, this subsection shall apply only to those areas of the plat devoted to residential uses.
B. The recreational open space may include waterways, detention/retention areas, and ponds provided that those areas do not constitute more than fifty percent (50%) of the amount of recreational open space required in subsection A of this section.
C. Where the proposed subdivision abuts undeveloped lands, the recreational open space land may be located adjacent to the subdivision boundaries with the undeveloped land, at the discretion of the city council, to allow the recreational open space to be increased in size when the adjacent property develops. (Ord. 52-09, 10-19-2009)
A. The subdivider or developer shall grade and seed the recreational open space.
B. Where the recreational open space is located adjacent to a street, the subdivider or developer shall be responsible for the installation of utilities and other improvements required along that street segment. The developer shall also provide utility service laterals for water and sewer.
C. The subdivider or developer shall be responsible for installing satisfactory ground cover and controlling erosion on recreational open space that has been disrupted as a result of development activities. (Ord. 52-09, 10-19-2009)
A. After the effective date hereof, the sustainable subdivision development tools apply to all new major subdivisions.
B. After a preapplication conference, the subdivider shall submit a preliminary plat and other written or graphic materials necessary to demonstrate what sustainable subdivision tools will be incorporated into the proposed subdivision.
C. New subdivisions shall achieve a minimum score of forty (40) points by utilizing the following list of sustainable subdivision development tools:
Conservation subdivision. Development is clustered to optimize open space, preserve natural features, protect environmentally sensitive areas, and minimize infrastructure demands. | 40 |
Cottage design subdivision. Development reflects traditional neighborhood design, with smaller lots, reduced setbacks, narrower rights of way, smaller building footprints, alleys and/or clustering. | 30 |
Solar subdivision. Development includes 70 percent "solar lots" that have a minimum north-south dimension of 75 feet and a front line orientation that is within 30 degrees of the true east-west axis. | 30 |
Complete street design throughout the subdivision. | 15 |
Permeable street pavement throughout the subdivision. | 15 |
The development incorporates walking/bike trails. These trails should be connected to the development and trails outside the development to the greatest extent possible. | 15 |
Green building code compliance for 100 percent of dwelling units throughout the subdivision. | 10 |
Rain gardens required by covenant for at least 80 percent of lots throughout the subdivision. | 10 |
Green building code compliance for 50 percent of dwelling units throughout the subdivision. | 5 |
Native and regionally appropriate trees and vegetation are preserved or planted which limits turf grass, limits water demand, improves infiltration or filtration, and enhances the natural environment. Such vegetation is phased so denuded areas are quickly vegetated. Turf grass should not exceed 30 percent of the landscaped area. | 5 |
No curb and gutter on city streets with appropriate bioswales and sidewalks. The development incorporates detention basins for property on site stormwater management. Retention basins can be used as an open water amenity feature for on site stormwater management. | 5 |
Parkway/street trees are planted at approximately 35 foot intervals to reduce wind speeds, help stabilize the soil, and improve air quality. | 5 |
Specify the planting of trees on private property to increase site shading and reduce energy needs for houses. Place trees that lose their leaves in the fall on the south and west sides of the house to provide shade to lower cooling costs. Evergreen trees planted on the north and west sides protect against winter winds, which can help reduce heating costs. | 5 |
The development implements innovative infiltration or filtration techniques such as rain gardens, bioswales, French drains, etc. | 5 |
Use of any pavement that reduces the heat island effect throughout the subdivision, such as light colored concrete. | 5 |
Other best management practices, as per city planner or city engineer. | 5 |
