[Ord. No. 3674 §§1—3, 8-17-2005]
This Article contains specific landscaping requirements relating
to the use or development of properties within the City of Hazelwood.
Certain land uses, because of their character and intensity, may create
an adverse impact on other land uses when developed and/or expanded.
The purpose of these regulations is two-fold: increase the compatibility
between adjacent land uses by requiring landscaping to mitigate the
negative impacts of noise, pollution, dust, debris, objectionable
views or motor vehicle headlight glare and other sources of artificial
light from spilling onto adjoining roadways or properties; and to
shield unsightly views, delineate functional areas within a lot and
establish an aesthetically pleasing urban streetscape.
[Ord. No. 3674 §§1—3, 8-17-2005]
All site plans submitted for a building permit shall include a landscape plan. The following uses are exempt from this requirement: single-family dwellings in the "NU", "R-1", "R-2", "R-3", "R-4" and "R-5" Residential Districts; single-family and duplex dwellings in the "R-6" Residential District; and permitted uses in the "P" Public District. Non-residential Special Land Use Permits within these districts, however, are also subject to the following landscaping requirements. All applications for a Planned District shall also include a landscape plan. (See Article VII, Planned Districts)
