Community Landscape Code

Landscaping, On-Storm water Management, Tree Preservation, Irrigation, Water Conservation 

 

Section 17.1.  Recitals, Purpose And Intent

A. Whereas the purpose of this Part is to provide minimum landscaping and on-site storm water management requirements

 

B. The (Municipal Council) has determined that the use of urban Best Management Practices such as on-site storm water management procedures

 

C. Further, the standards, requirements and administrative procedures of this Part seek establish city wide management of natural resources through the establishment of an administrative program properly staffed and managed to promote the preservation, protection and enhancement of nature’s unique features and resources with particular emphasis on the urban drainage system and its network of swales, settling basins and streams including forest canopy floor, open water resources and existing wetland patterns consistent with appropriate requirements of (Section 404 of the Clean Water Act) and the (National Environmental Policy Act.)

 

D. Lastly, landscape design standards contained within this

1) Minimal site landscaping, on-site storm water management, irrigation design, water conservation, tree preservation and tree planting are design principles consistent with protecting nature in this community.

a) Planted buffers, screens, landscape plantings, ground cover treatments, plant material installation and landscape maintenance standards will perpetuate community development, economic expansion and redevelopment of older neighborhoods toward sustainability and lower energy consumption.

b) On-site storm water management practices will reduce the volume of downstream water that must be managed at public expense by the maintenance, enlargement and repair of expensive underground catch basins, conveyance pipe, open ditches and large retention ponds.

c) Irrigation, water conservation principles and the use of re-claimed water contained within this ordinance also will work to reduce water waste and reuse storm water to minimize the consumption of potable water for landscape irrigation, outdoor cleaning and lawn sprinkling.

d) Tree preservation practices and replanting within lot development yards will conserve the urban forest canopy that provides many public services that are critical in maintaining the quality of life traditional with this community.

 

E. Section 17 of the Unified Development Code, a section of the Municipal Code shall be known as “The Community Landscape Code
