§ 195-204 Conservation (C) District.
A.
Purpose. The Conservation (C) District is established to protect West Hanover's environmental sensitive areas. The application of this district is to lands identified in the Township's Comprehensive Plan and Natural Resources Inventory as having severe limitations based on their physiographic, geologic, hydrologic, soil, and vegetative characteristics. The district is intended to support policies established in the Comprehensive Plan for lands to be preserved for conservation by discouraging urban land uses and development in these areas and maintaining open areas and low-intensity land uses. This district identifies these sensitive lands and distinguishes them from other areas in the Township which are identified in the Comprehensive Plan as appropriate for urban land uses. The provisions of this district have been specifically formulated to satisfy Section 604.(1) of the Pennsylvania Municipalities Planning Code, which requires local zoning ordinances to "promote, protect and facilitate the preservation of the natural, and historic values in the environment and preservation of forests."[1]

§ 195-206 Rural Residential (RR) District.
A.
Purpose. The Rural Residential (RR) District is established to provide areas for rural residential development that do not impact agricultural lands or create further sprawling patterns of development. The district is located adjacent to areas of existing residential development as identified in the Comprehensive Plan. Further residential development is encouraged for these areas. Single lot or minor subdivisions of low density are anticipated in these areas due to the limited availability of community facilities. The RR District area is adjacent to the agricultural district; however, agricultural uses are not encouraged because this district is comprised primarily of small lots. The regulations for this district are designed to protect and stabilize these essential development characteristics and promote and encourage quality rural development.

§ 195-216 Floodplain Overlay (FPO) District.
A.
Purpose. The purpose of the Floodplain Overlay (FPO) District is to:
(1)
Regulate the permitted use of flood-prone areas.
(2)
Where there happens to be any conflict between the provisions or requirements of any of the floodplain districts and those of any underlying district, the more restrictive provisions and/or those pertaining to the floodplain districts shall apply.
(3)
In the event any provisions concerning a floodplain district are declared inapplicable as a result of any legislative or administrative actions or judicial discretion, the basic underlying district provision shall remain applicable.
(4)
Require the utilization of appropriate construction practices and design standards in order to prevent or minimize flood damage in the future.
(5)
Reduce financial burdens imposed on the community, its governmental units, and its residents by preventing the unwise use and development of property in areas subject to flooding.
B.
Authority. Sections 604 and 605 of the MPC and the Pennsylvania Flood Plain Management Act (Act 166-1978)[1] grant municipalities the authority to identify flood-prone areas subject to periodic flooding and regulate with specific control the permitted use, type of construction and height of floor levels above base flood elevation permitted in the area to lessen or avoid the hazards to persons and damage to property resulting from the accumulation of storm- or floodwaters.
[1]
Editor's Note: See 53 P.S. § 10604 and 53 P.S. § 10605 and 32 P.S. § 679.101 et seq., respectively.
C.
Applicability. Except as modified by the FPO, the provisions of the applicable base zoning district(s) shall apply to all development within the boundary of the designated area. If regulations conflict, the applicable FPO regulations shall prevail. Whenever the FPO District is established, any subsequent application to change the base zoning district shall not be construed to be an application to eliminate the FPO District for the property covered by the application. An intent to eliminate the FPO district on a given property shall be expressly stated to be part of the application.
D.
Floodplain Management Ordinance. Chapter 108, Floodplain Management, of the Code of the Township of West Hanover establishes the requirements for floodplain management, including general provisions, interpretations and definitions, establishes floodplain areas, boundary disputes, alterations, criteria for building and site plan approval, administration, appeals and penalties, government actions, and municipal liability.
E.
Boundaries of district.
(1)
To the extent the Zoning Map and Chapter 108, Floodplain Management, of the Code of the Township of West Hanover identify areas prone to or otherwise at risk of flood, including without limitation by reference to a Flood Insurance Rate Map or FEMA Flood Insurance Study, such areas shall be deemed identified as flood-prone areas for purposes of this chapter and included within the FPO District.
(2)
Boundaries indicated as approximately following the center lines of street or alley rights-of-way shall be construed to follow such center lines;
(3)
Boundaries indicated as parallel to, or extensions of features indicated in the above shall be so construed; and
(4)
Where physical or cultural features existing on the ground are different from those shown on the Flood Insurance Rate Map, or in other circumstances not covered by the above, the Zoning Officer shall interpret the FPO District boundaries.
F.
Interpretation of ordinance provisions. In interpreting the language of the Floodplain Overlay District and the extent of underlying zoning district regulation upon use of property, where doubt exists between regulations, the stricter regulation shall govern. Any challenges to the Township's interpretation of the applicability of the Floodplain Overlay Zoning District shall be appealed in accordance with the requirements outlined § 195-113, Appeals and boundary interpretation and appeals procedure, of this chapter and Article IX, Zoning Hearing Board and Other Administrative Proceedings, of the MPC.
§ 195-217 Riparian Buffer Overlay (RPO) District.
A.
Purpose. Under the authority of the MPC, as amended, other commonwealth and federal statutes, and in recognition of the fact that natural features contribute to the quality of life in the Township, the following riparian buffer regulations are enacted to provide reasonable controls governing the restoration, conservation, disturbance, and management of existing riparian corridors by establishing a designated Riparian Buffer Overlay Zoning District.
B.
The Riparian Buffer Overlay Zoning District shall apply to all properties or any other improvements that require subdivision or land development plan submission if they are within or touch the Riparian Buffer Overlay Zoning District within West Hanover Township.
C.
Any required riparian buffer preservation and maintenance shall remain the sole responsibility of each individual property owner or as otherwise stipulated by the West Hanover Township Stormwater Management Ordinance, Chapter 168 of the Code of the Township of West Hanover.
D.
In addition, the specific purposes and intent of this section are to:
(1)
Conserve the natural features important to land or water resources (e.g., headwater areas, groundwater recharge zones, floodways, floodplains, springs, streams, wetlands, woodlands, prime wildlife habitats).
(2)
Conserve natural, scenic, and recreation areas within and adjacent to riparian areas for the region's benefit.
(3)
Reduce the amount of nutrients, sediment, organic matter, pesticides, and other harmful substances that reach watercourses, wetlands, subsurface, and surface water bodies by using scientifically proven processes, including filtration, deposition, absorption, adsorption, plant uptake, and denitrification, and by stabilizing. Further, to minimize concentrated flows through the use of level spreaders and/or similar stormwater management devices used to disburse concentrated flow uniformly over the ground as sheet flow.
(4)
Improve and maintain the safety, reliability, and adequacy of the Township's water supply for domestic, agricultural, commercial, industrial, and recreational uses along with sustaining diverse populations of aquatic plants and animals.
(5)
Regulate the land use, siting, and engineering of development to be consistent with the intent and objectives of this section and accepted conservation practices, as well assure that the impacts of such development remain within the carrying capacity of existing natural resources.
(6)
Assist in the implementation of pertinent state laws concerning erosion and sediment control practices, specifically erosion control, of the Pennsylvania Clean Streams Law, Act 394, P.L. 1987, Chapter 102 of the Administrative Code (as amended October 10, 1980, Act 157 P.L.), Title 25, and any subsequent amendments thereto, as administered by the Pennsylvania Department of Environmental Protection and the Dauphin County Conservation District.
E.
Definition; establishment; width determination; applicability; and interpretation.
(1)
Definition. The Riparian Buffer Overlay is a zoning district consisting of areas surrounding swales, creeks, streams, water bodies, intermittent watercourses and delineated wetlands as well as those encountered during subdivision and land development. These areas intercept surface water runoff, subsurface flow, and deep groundwater flows from upland sources and remove or buffer the impact of nutrients, sediment, organic matter, pesticides, or other pollutants prior to entry into surface waters.
(2)
Establishment. The establishment of a Riparian Buffer Overlay Zoning District applies to the following areas which are identified on the officially adopted Zoning Map of West Hanover Township:
(a)
Lands adjacent to streams within West Hanover Township.
(b)
Lands adjacent to intermittent watercourses within West Hanover Township.
(c)
Lands, water bodies and wetlands as regulated by state and/or federal designation.
(d)
Similar land and/or water to those outlined above as encountered during the process of subdivision and land development within West Hanover Township.
(3)
Width determination.
(a)
Except as required by Chapter 102 of the Pennsylvania State Code, the Riparian Buffer Overlay shall be measured to be the greater of the limit of the 100-year floodplain or a minimum of 35 feet from the top of the streambank (on each side). Where the edge of waterway of an intermittent watercourse cannot be determined, the width of the Riparian Buffer Overlay Zoning District shall be measured beginning from the center line of the channel. Where a defined bed and bank exist, the edge shall be established based on bank full flow.
(b)
Where slopes of 25% or greater are located within the Riparian Buffer Overlay area defined in Subsection E(3)(a), this buffer area shall extend the entire distance of the steep sloped area, not to exceed 100 feet past the nearest point of the Riparian Buffer Overlay area defined in Subsection E(3)(a). The sloped area shall be measured where there are five adjacent contour intervals of two feet each such that, in aggregate, they delineate a slope of at least 25%.
(c)
The Riparian Buffer Overlay Zoning District shall also include a minimum buffer width of 35 feet around the entire perimeter of the outer edge of wetlands and water bodies greater than 5,000 square feet in area that are not located along a stream.
(4)
Applicability. The provisions of this section shall apply as follows:
(a)
The developer/applicant shall be responsible for identifying the location of the Riparian Buffer Overlay Zoning District boundary on any plan that is submitted to West Hanover Township for the following:
[1]
Subdivision or land development as defined in Chapter 173, Subdivision and Land Development, of the Code of the Township of West Hanover.
[2]
Approval for improvements that require a zoning or building permit. Although mitigation may not be required for such activity, the boundary must still be delineated. Such permit(s) shall only be required when construction or erection of any buildings or structure(s) within or touching the Riparian Buffer Overlay Zones of West Hanover Township is located on the ground or attached to something on the ground and is greater than 1,000 square feet in size.
(b)
This initial delineation of the overlay district boundary shall be subject to review and approval by the West Hanover Township Zoning Officer.
(c)
These requirements shall not apply to any existing primary or accessory buildings or to any of the following: agricultural uses, transportation facilities, fences, lawns, gardens, utility lines, decks and piers, or to interior renovations, septic and essential services.
(5)
Interpretation of ordinance provisions. In interpreting the language of the Riparian Buffer Overlay District and the extent of the underlying zoning district(s) regulating the use of property, where doubt exists between regulations, the stricter regulation shall govern. Any challenges to the Township's interpretation of the applicability of the Riparian Buffer Overlay Zoning District shall be appealed in accordance with the requirements outlined § 195-113, Appeals and applications, of this chapter.
F.
