To promote, protect and facilitate any or all of the following: the public health, safety, morals, and the general welfare; coordinated and practical community development and proper density of population; emergency management preparedness and operations, the provisions of adequate light and air, access to incident solar energy, police protection, vehicle parking and loading space, transportation, water, sewerage, schools, recreational facilities, public grounds, the provision of a safe, reliable and adequate water supply for domestic, commercial, agricultural or industrial use, and other public requirements; as well as preservation of the natural, scenic and historic values in the environment and preservation of forests, wetlands, aquifers and floodplains.

To prevent one or more of the following: overcrowding of land, blight, danger and congestion in travel and transportation, loss of health, life or property from fire, flood, panic and other dangers.

To preserve prime agricultural and farmland considering topography, soil type and classification, and present use.

To protect and preserve natural resources, and to restrict use and structures at or near bodies of water, places of steep slope and other areas of hazardous geological or topographic features.

To ensure a legacy of environmentally selective, sensible and sensitive land use and development.

To provide for the use of land within the Township for residential housing of various dwelling types encompassing all basic forms of housing, including single-family and two-family dwellings, and a reasonable range of multi-family dwellings in various arrangements, mobile homes and mobile home parks.

To accommodate reasonable overall community growth, including population and employment growth, and opportunities for development of a variety of residential dwelling types and nonresidential uses.

The sharply undulating topography of Charlestown Township moves recurrently from steeply and very steeply sloped and ridged woodlands, across the lowlands of the swift flowing Pickering Creek and tributary streams, to steeply sloped ridge land, and then to upland prime agricultural lands. The residential and farm residential areas and agricultural areas of Charlestown Township overlay this topography and are predominantly dependent upon on-site individual wells for water supply.

The residential and farm residential areas and agricultural areas are vulnerable to the ravages of uncontrolled stormwater runoff. They are defenseless from both the contamination and depletion of the groundwater water supply.

For the protection of not only the existing but also the future residents of Charlestown Township, the residential and farm residential areas and agricultural areas require the most environmentally selective, sensitive and protective requirements for land use and development, housing placement, well and septic systems siting and road locations, all of which must be considered on a unified basis with lot area, setback and other like requirements traditionally the subject of land use regulations.

Charlestown Township consists of 8,064 acres of land substantially within the Pickering Creek Watershed of the Schuylkill Sub-basin. Approximately 90% of Charlestown Township is within a zone of low groundwater capability (0-10 gallons per minute). This condition makes it imperative, for the welfare of current and future Township residents, that land use and development and groundwater supply be compatible and that groundwater withdrawal and groundwater recharge be consistent. Further, the northern half of Charlestown Township is dominated by a zone of soils having severe soil limitations for on-site sanitary sewer systems and the southern half of Charlestown Township is dominated by a zone of soils have moderate soils limitations therefor. These conditions underscore the imperative to make land use and development consistent with natural environmental features and conditions, which may not be easily preserved or improved but which may be summarily degraded, depleted or destroyed.

Charlestown Township is located more than 25 miles northwest of Philadelphia; is not served by public transportation facilities; and is predominately dependent upon a rural, narrow, serpentine, sinuous or sharply undulating road system, owned and maintained by the commonwealth, carved decades ago into Charlestown Township's rock and stream constraining topography.

Instilling order in the growth and development of Charlestown Township, and minimizing the sprawling effect of development by regulating the type and locations of development in accordance with environmental resource and land use compatibility, and with the support and service characteristics of existing community facilities and utilities.

Conserving open space and natural features, and preserving natural, scenic and historic values in and resources of the environment and maintaining environmental stability through the control of land use and development in the floodplain, forests, and wetlands and on steep and very steep slopes and in relation to surface, groundwater and aquifer resources susceptible to degradation by wastes, sediments and other pollutants.

Creating the setting for diversified residential, enterprise, civic and community facilities by enabling a variety and range of housing types and intensities within Charlestown Township at a proper overall density of population and securing the community service and recreational facilities which would support and complement the residential, enterprise and community land use.

Encouraging the continuation of agricultural land use by the conservation of prime agricultural soils through the exercise of sound cultivation and grading techniques, and the promotion of existing agricultural practices through the attainment of lower tax assessments for land which is utilized for agricultural purposes.

Economizing on infrastructure investment, and encouraging the use of existing public facilities by promoting a strong relationship between the availability of public utilities including the provision of safe, reliable, and adequate water supply; a safe and convenient road network and an effective stormwater management system, and the type and location of future development.

Preserving historic and cultural resources and maintaining the visual character of the landscape by promoting the preservation of historic sites and areas, and the continuation of farming and discouraging types of and locations for development that will create detrimental changes of the existing character of Charlestown Township, in particular the amenities of light, air and visual enjoyment.
