Footnotes:
--- (3) ---

Editor's note— Ord. No. 385, § 1, adopted February 19, 2007, amended chapter 19 in its entirety to read as herein set out. Formerly, chapter 19 pertained to similar subject matter, and derived from Ord. No. 346, §§ 1901—1909.


Sec. 1901.- Purpose.

It is the intent of this section to require landscaping and screening to buffer the negative impacts between incompatible land uses; to minimize the adverse effects of certain outdoor activities upon their surroundings; and to improve the appearance of parking areas and street frontages within the community. It is further intended to preserve and enhance the aesthetic qualities, character, privacy, and land values of property within the village. For those projects requiring a special use permit and site plan approval, a landscape plan shall be prepared by a registered landscape architect.

(Ord. No. 385, § 1, 2-19-2007)

Sec. 1902. - Buffer zones required.

1.

A buffer zone shall be required on the subject parcel between abutting zoning districts, as indicated on the required buffers table.

2.

A buffer zone shall be required on the subject parcel even if the adjacent parcel is unimproved land.

3.

When any developed parcel changes to a more intense land use or a special land use approval or a site plan review is required, a buffer zone shall be provided in compliance with this chapter.

4.

If existing conditions on the subject parcel are such that a parcel cannot comply with the buffer zone requirements, the planning commission shall determine the character of the buffer based on the following criteria:

a.

Traffic impacts;

b.

Building and parking lot coverage;

c.

Outdoor sales, display, or manufacturing area;

d.

Physical characteristics of the site and surrounding area such as topography, vegetation, etc.;

e.

Views and noise levels;

f.

Health, safety, and welfare of the village;

g.

Proximity or potential proximity of adjacent residential uses.

5.

The planning commission may require additional screening where a buffer zone is not required by section 1903. In application of this standard the planning commission shall consider the character and type of development proposed and its compatibility with adjacent land uses and zoning.
