The singular or cumulative effect of any of the foregoing could adversely impact the character of the Township, decrease property values, render the land unfit and unsuitable for its most appropriate use and negatively affect the health, safety and general welfare of the inhabitants of the Township. The Township desires to regulate and control indiscriminate and excessive cutting of trees within the Township. The Township strives to preserve the maximum possible number of trees in the course of development of a site as well as protect larger, older specimens of trees. Additionally, the Township seeks to encourage innovative design and grading, promote the preservation of existing trees and provide a plan for the replacement of trees. It is recognized that there is a strong relationship between the integrity of the Township's water resources, development on steep slopes, tree removal, soil disturbance, stormwater management and the general use of land resources. Therefore, the Township finds that the appropriate management of these resources is an important health, safety and general welfare concern. |

Increased drainage control cost; |
Increased soil erosion and sedimentation; |
Decreased fertility of the soil; |
Degradation of water resources; |
Decreased groundwater-recharge; |
Increased buildup of atmospheric carbon; |
The establishment of a heat island effect; |
Increased dust and pollution; |
The singular or cumulative effect of any of the foregoing could adversely impact the character of the Township, decrease property values, render the land unfit and unsuitable for its most appropriate use and negatively affect the health, safety and general welfare of the inhabitants of the Township. The Township desires to regulate and control indiscriminate and excessive cutting of trees within the Township. The Township strives to preserve the maximum possible number of trees in the course of development of a site as well as protect larger, older specimens of trees. Additionally, the Township seeks to encourage innovative design and grading, promote the preservation of existing trees and provide a plan for the replacement of trees. It is recognized that there is a strong relationship between the integrity of the Township's water resources, development on steep slopes, tree removal, soil disturbance, stormwater management and the general use of land resources. Therefore, the Township finds that the appropriate management of these resources is an important health, safety and general welfare concern. |
