Footnotes:
--- (10) ---

Editor's note— Ord. No. 2010-6, § 2(Att. A), adopted Oct. 12, 2010, amended in its entirety the former Art. IX, §§ 30-230—30-241, and enacted a new Art. IX as set out herein. The former Art. IX pertained to Landscape Regulations and derived from Ord. No. 2000-5, § 2, 5-9-00; Ord. No. 2000-6, § 2, 5-9-00.


Sec. 30-230.- Purpose and intent.

It is the intent of this article to establish and require enforcement of landscape standards that will enhance, improve, and maintain landscaping in the Village through the application of following principles:

(a)

Promote xeriscape by encouraging the use of drought-tolerant landscape materials, grouping of plant material by water requirements and irrigation systems that conserve the use of potable water supplies.

(b)

Use landscape materials to visually define the hierarchy of roadways, and to provide shade and visual edge along roadways.

(c)

Prevent the destruction of the existing tree canopy and promote its expansion.

(d)

Provide for the preservation of the existing natural forest communities, specimen trees, re-establish the native habitat along the beach, and encourage the use of native plant material.

(e)

Promote the use of trees and shrubs for energy conservation by encouraging cooling through the provision of shade and the channeling of breezes, thereby helping to offset global warming and effects of added absorption of carbon dioxide.

(f)

Contribute to the processes of air movement, air purification, oxygen regeneration, ground water recharge, stormwater runoff retention, while aiding in the abatement of noise, glare, heat, air pollution and dust generated by impervious areas.

(g)

Improve the aesthetic appearance of the Village through the use of plant material, thereby protecting and increasing property values.

(h)

Reduce the negative impacts of invasive plant species as identified by the Florida Exotic Pest Plan Council and prohibit the use of noxious exotic plants which invade native plant communities.

(i)

Promote the concept of planting the appropriate tree in the correct location to avoid problems such as clogged sewers, cracked sidewalks, and power service interruptions.
