A.
Intended purpose.
(1)
In the interest of the public health, safety and welfare, the regulations of the Conservation District are designed and intended to protect areas in the Borough for the preservation of the natural environment and to permit and encourage the retention of open land which will be so located and designed as to constitute a harmonious and appropriate part of the physical development of the Borough as provided for in the Adamstown Borough Comprehensive Plan. The soils in these areas are predominantly floodplain, wet and/or shallow soils. And these districts contain open areas of streams, creeks and drainageways. These districts are established to preserve the areas along streams which are subject to flooding from encroachments that will impair their usefulness as natural drainageways.
(2)
The specific intent of the district is:
(a)
To combine with present regulations certain restrictions made necessary for areas consisting of floodplain, wet and/or shallow soils.
(b)
To prevent the erection of structures in areas unfit for human usage by reason of drainageways from flooding.
(c)
To minimize danger to the public health by protecting the water supply and promoting safe and sanitary drainage.
(d)
To reduce the financial burdens imposed upon the community, the governmental units, and its individuals.
(e)
To permit only those uses in the conservation areas compatible to the preservation of natural conditions which are conducive to the maintenance of unimpeded flow of floodwaters, constant rates of water flow throughout the year by:
(f)
To provide sufficient drainagecourses to carry abnormal flows of stormwater in periods of heavy precipitation.
