A. 
Floodplain areas. The identified floodplain area shall consist of the following specific areas:
(1) 
FW (floodway area): the areas identified as "floodway" in the AE Zone in the Flood Insurance Study prepared by the FEMA. The term shall also include floodway areas which have been identified in other available studies or sources of information for those floodplain areas where no floodway has been identified in the Flood Insurance Study.
(2) 
FF (flood-fringe area): the remaining portions of the one-hundred-year floodplain in those areas identified as an AE Zone in the Flood Insurance Study, where a floodway has been delineated.
(3) 
FE (special floodplain area): the areas identified as Zone AE in the Flood Insurance Study, where one-hundred-year flood elevations have been provided, but no floodway has been delineated.
(4) 
FA (general floodplain area): the areas identified as Zone AE in the Flood Insurance Study for which no one-hundred-year flood elevations have been provided. When available, information from other federal, state and other acceptable sources shall be used to determine the one-hundred-year elevation, as well as a floodway area, if possible. When no other information is available, the one-hundred-year elevation shall be determined by using a point on the boundary line of the identified floodplain area which is nearest the construction site in question.
B. 
Hydrologic and hydraulic engineering. In lieu of the above, the Township may require the applicant to determine the elevation with hydrologic and hydraulic engineering techniques. Hydrologic and hydraulic analyses shall be undertaken only by professional engineers or others of demonstrated qualifications, who shall certify that the technical methods used correctly reflect currently accepted technical concepts. Studies, analyses, computations, etc., shall be submitted in sufficient detail to allow a thorough technical review by the Township.
C. 
Changes in identification of area. The identified floodplain area may be revised or modified by the Township where studies or information provided by a qualified agency or person documents the need for such revision. However, prior to any such change, approval must be obtained from the Federal Insurance Administration (FIA).
D. 
Variance procedures and conditions for flood areas.
(1) 
Requests for variances shall be considered by the Township in accordance with the following:
(a) 
No variance shall be granted for any construction, development, use or activity within any floodway area that would cause any increase in the one-hundred-year flood elevation.
(b) 
No variance shall be granted for any construction, development, use or activity within any FE area that would, together with all other existing and anticipated development, increase the one-hundred-year flood elevation more than one foot at any point.
(c) 
Except for a possible modification of the 1 1/2 foot freeboard requirement involved, no variance shall be granted for any of the other requirements pertaining specifically to development regulated by special permit or to development which may endanger human life.
(d) 
If granted, a variance shall involve only the least modification necessary to provide relief.
(e) 
In granting any variance, the Township shall attach whatever reasonable conditions and safeguards it considers necessary in order to protect the public health, safety and welfare and to achieve the objectives of this chapter.
(f) 
Whenever a variance is granted, the Township shall notify the applicant in writing that:
[1] 
The granting of the variance may result in increased premium rates for flood insurance.
[2] 
Such variance may increase the risks to life and property.
(g) 
In reviewing any request for a variance, the Township shall consider, at a minimum, the following:
[1] 
That there is good and sufficient cause.
[2] 
That failure to grant the variance would result in exceptional hardship to the applicant.
[3] 
That the granting of the variance will (a) neither result in an unacceptable or prohibited increase in flood heights, additional threats to public safety or extraordinary public expense nor (b) create nuisances, cause fraud on or victimize the public or (c) conflict with any other applicable state or local ordinances and/or regulations.
(h) 
A complete record of all variance requests and related actions shall be maintained by the Township. In addition, a report of all variances granted during the year shall be included in the annual report to the Federal Insurance Administration.

Driveway spacing shall be measured from the closest edge of the pavement to the next closest edge of the pavement. (See definition section and Appendix A, Figure I.[2]) The projected future edge of the pavement of the intersecting road shall be used in measuring corner clearance, where widening, relocation, or other improvement is indicated in an adopted local transportation plan or transportation plan of the state, county or Township.
[2]
Editor' Note: Appendix A is included as an attachment to this chapter.
(5) 
If the connection spacing of this code cannot be achieved, then a system of joint use driveways may be required in accordance with the variance standards set forth herein.
C. 
Corner clearance.
(1) 
Corner clearance for connections shall meet or exceed the minimum connection spacing requirements for that roadway.
(2) 
New connections shall not be permitted within the functional area of an intersection or interchange as defined by the connection spacing standards of this code.
(3) 
In addition to the required minimum lot size, all corner lots shall be of adequate size to provide for required front yard setbacks and corner clearance on street frontage.
D. 
Joint and cross access.
(1) 
Adjacent commercial or office properties classified as major traffic generators (for example, shopping plazas, office parks) shall provide a cross-access drive and pedestrian access to allow circulation between sites.
E. 
A system of joint-use driveways and cross-access easements shall be established wherever feasible in the Overlay Zone. The Overlay Zone shall apply to the full extent of these roads throughout Unity Township.
(1) 
The building site shall incorporate the following:
(a) 
A continuous service drive or cross-access corridor extending the entire length of each block served to provide for driveway separation consistent with the access management standards.
(b) 
A design speed of 10 mph and sufficient width to accommodate two-way travel aisles designed to accommodate automobiles, service vehicles, and loading vehicles.
(c) 
Stub-outs and other design features to make it visually obvious that the abutting properties may be tied in to provide cross access via a service drive.
(d) 
A unified access and circulation system plan that includes coordinated or shared parking areas is encouraged wherever feasible.
(2) 
Shared parking areas shall be permitted a reduction in required parking spaces if peak demand periods for proposed land uses do not occur at the same time periods.
(3) 
Pursuant to this subsection, property owners shall:
(a) 
Record an easement with the deed allowing cross access to and from other properties served by the joint-use driveways and cross-access or service drive;
(b) 
Record an agreement with the deed that remaining access rights along the thoroughfare will be dedicated to Unity Township and preexisting driveways will be closed and eliminated after construction of the joint-use driveway;
(c) 
Record a joint maintenance agreement with the deed defining maintenance responsibilities of property owners.
F. 
Access connection and driveway design.
(1) 
Driveway approaches must be designed and located to provide an exiting vehicle with an unobstructed view. Construction of driveways along acceleration or deceleration lanes and tapers is discouraged due to the potential for vehicular weaving conflicts.
(2) 
Driveway width and flair shall be adequate to serve the volume of traffic and provide for rapid movement of vehicles off of the major thoroughfare, but standards shall not be so excessive as to pose safety hazards for pedestrians, bicycles, or other vehicles. (See Appendix A, Figures 2 and 3.[3])
[3]
Editor's Note: Appendix A is included as an attachment to this chapter.
(3) 
The length of driveways or "throat length" (see Appendix A, Figure 4[4]) shall be designed in accordance with the anticipated storage length for entering and exiting vehicles to prevent vehicles from backing into the flow of traffic on the public street or causing unsafe conflicts with on-site circulation. Throat length should be determined on a case-by-case basis, but generally varies according to the number of trips generated by the land use. The following Table provides examples of different sized retail establishments and recommended driveway throat lengths. A traffic impact study based on peak-hour demand will be conducted to determine the extent of potential queuing problems and how best to resolve them. These measures are generally acceptable for the principal access to a property and are not intended for minor driveways.

G. 
Requirements for outparcels and phased development plans.
(1) 
In the interest of promoting unified access and circulation systems, development sites under the same ownership or consolidated for the purposes of development and comprised of more than one building site shall not be considered separate properties in relation to the access standards of this code. The number of connections permitted shall be the minimum number necessary to provide reasonable access to these properties, not the maximum available for that frontage. All necessary easements, agreements, and stipulations required under this subsection shall be met. This shall also apply to phased development plans. The owner and all lessees within the affected area are responsible for compliance with the requirements of this code and both shall be cited for any violation.
(2) 
All access to the out parcel must be internalized using the shared circulation system of the principle development or retail center. Access to out parcels shall be designed to avoid excessive movement across parking aisles and queuing across surrounding parking and driving aisles.
(3) 
The number of outparcels shall not exceed one per 10 acres of site area, with a minimum lineal frontage of 300 feet per outparcel or greater where access spacing standards for that roadway require. In such cases the right of direct access to the roadway shall be dedicated to Unity Township and recorded with the deed.
H. 
Emergency access. In addition to minimum side, front, and rear yard setback and building spacing requirements specified in this code, all buildings and other development activities, such as landscaping, shall be arranged on site so as to:
(1) 
Provide safe and necessary access for emergency vehicles around the complete property perimeter; and
(2) 
Provide necessary access to all hydrants and standpipes.
I. 
Transit access.
(1) 
In commercial or office zoning districts where transit service is available or is planned to be available within five years, provisions shall be made for adequate transit access, in the form of turn-around loops or turnout bays. At a minimum, in the case of a loop or cul-de-sac, entrance curves shall have a thirty-five-foot radius, and the internal circle shall have an inside radius of 30 feet and an outside radius of 52.5 feet. In the case of turnout bays, the curve radius shall be 35 feet, the distance from the roadside edge to the inside edge of the outside radius shall be 52.5 feet.
(2) 
The transit cart ways shall be sufficiently strengthened in accordance with accepted engineering standards to support the additional weight of transit vehicles.
(3) 
Pedestrian access shall be provided to transit stops.
J. 
Corridor access management overlay. The following requirements shall apply to segments of designated thoroughfares that are planned for commercial or intensive development. All land in a parcel having a single tax code number, as of September 25, 2001, and fronting on a section of roadway included in the Overlay Zone, shall be entitled one driveway/connection per parcel as of right on said public thoroughfare(s). When subsequently subdivided, either as metes and bounds parcels or as a recorded plat, parcels designated herein shall provide access to all newly created lots via the permitted access connection. This may be achieved through subdivision roads, joint and cross access, service drives, and other reasonable means of ingress and egress in accordance with the requirements of this code. The following standards shall also apply:
(1) 
Parcels with large frontages may be permitted additional driveways at the time of adoption of these requirements, provided they are consistent with the applicable driveway spacing standards.
(2) 
Existing parcels with frontage less than the minimum connection spacing for that corridor may not be permitted a direct connection to the thoroughfare under this section where the Township Supervisors determine that alternative reasonable access is available to the site. The Township Supervisors, in their sole discretion, may allow for a temporary driveway as provided in Subsection G with the stipulation agreed, in writing, by the property owner that joint and cross access shall be established as adjacent properties develop.
(3) 
Additional access connections may be allowed where the property owner demonstrates to the Township that safety and efficiency of travel on the thoroughfare will be improved by providing more than one access to the site.
(4) 
No parking or structure other than signs shall be permitted within 35 feet of the roadway right-of-way. The thirty-five-foot buffer shall be landscaped with plants suitable to the soil and in a manner that provides adequate sight visibility for vehicles exiting the site. Property owners shall be permitted to landscape the right-of-way, pursuant to an approved landscaping plan.
(5) 
Permitted connections shall be identified on a map that shall be adopted by reference, and that portion of a corridor affected by these overlay requirements shall be delineated on the Unity Township Zoning Map.
K. 
Reverse frontage.
(1) 
Access to double-frontage lots shall be required on the street with the lower functional classification.
(2) 
When a residential subdivision is proposed that would abut an arterial street, it shall be designed to provide through lots along the arterial street with access from a frontage road or interior local road. Access rights from these lots to the arterial street shall be dedicated to Unity Township and recorded with the subdivision plan. A berm or buffer yard may be required at the rear of through lots to buffer residences from traffic on the arterial. The berm or buffer yard shall not be located within the public right-of-way.
L. 
Lot width-to-depth ratios. To provide for proper site design and prevent the creation of irregularly shaped parcels, the depth of any lot or parcel shall not exceed three times its width.
M. 
Shared access.
(1) 
Subdivisions with frontage on the state highway system shall be designed into shared access points to and from the highway. Normally a maximum of two accesses should be allowed regardless of the number of lots or businesses served.
(2) 
Subdivisions on a single residential access street ending in a cul-de-sac shall not exceed 25 lots or dwelling units, and the cul-de-sac shall have a minimum cart-way radius of 50 feet.
N. 
Connectivity.
(1) 
The street system of a proposed subdivision shall be designed to coordinate with existing, proposed, and planned streets outside of the subdivision as provided in this section.
(2) 
Wherever a proposed development abuts unplatted land or a future development phase of the same development, street stubs shall be provided as deemed necessary by Unity Township to provide access to abutting properties or to logically extend the street system into the surrounding area. All street stubs shall be provided with temporary turn-around or culs-de-sac unless specifically exempted by Unity Township, and the restoration and extension of the street shall be the responsibility of any future developer of the abutting land.
(3) 
Collector streets shall intersect with collector or arterial streets at safe and convenient locations.
(4) 
Sub-collector and local residential access streets shall connect with surrounding streets to permit the convenient movement of traffic between residential neighborhoods or facilitate emergency access and evacuation, but such connections shall not be permitted where the effect would be to encourage the use of such streets by substantial through traffic.
O. 
Site plan review procedures.
(1) 
In addition to the requirements for a subdivision or land development, applicants located within the Transportation Overlay District shall submit a preliminary site plan for review by the Township which, at a minimum, must contain:
(a) 
The location of access point(s) on both sides of the road where applicable;
(b) 
Distances to neighboring constructed access points, median openings, traffic signals, intersections, and other transportation features on both sides of the property;
(c) 
The number and direction of lanes to be constructed on the driveway plus striping plans;
(d) 
All planned transportation features (such as auxiliary lanes, signals, etc.);
(e) 
Trip generation data or appropriate traffic studies;
(f) 
Parking and internal circulation plans;
(g) 
A plat map showing property lines, right-of-way, and ownership of abutting properties; and
(h)

(2) 
The following criteria shall be followed in the layout, design and review of subdivisions and/or site plans in this overlay district to insure adequacy of access:
(a) 
The road system shall be designed to meet the projected traffic demand, and the road network shall consist of a hierarchy of roads designed according to function.
(b) 
The road network shall follow the natural topography and preserve natural features of the site as much as possible. Alignments shall be planned so that grading requirements are minimized.
(c) 
Access shall be properly placed in relation to sight distance, driveway spacing, and other related considerations, including opportunities for joint and cross access. Entry roads shall be clearly visible from the major arterials.
(d) 
Units shall front on residential access streets rather than major roadways.
(e) 
Automobile movement shall be provided within the site without having to use the peripheral road network.
(f) 
The road system shall provide adequate access to buildings for residents, visitors, deliveries, emergency vehicles, and garbage collection.
(g) 
The edges of the roadways shall be landscaped. Sidewalks shall be provided alongside the road and they shall be set back sufficiently from the road. A landscaped planting strip between the road and the sidewalk shall be provided.
(h) 
The pedestrian path system shall link buildings with parking areas, entrances to the development, open space, and recreational and other community facilities.
(3) 
The Township reserves the right to require a traffic and safety analysis where safety is an issue or where significant problems already exist.
(4) 
Applicants must be notified by the Township if any additional information is needed to complete the application within 10 days of the date the application is filed.
(5) 
Upon review of the access application, Unity Township may approve the access application, approve with conditions, or deny the application. This must be done within 60 days of receiving the complete application unless extended by agreement of the applicant.
(6) 
Any application that involves access to a State Highway System shall be reviewed by the Pennsylvania Department of Transportation for conformance with state highway occupancy permit standards. Where the applicant requires access to the State Highway System, and a zoning approval, subdivision or site plan review and/or approval is also required, all development review shall be coordinated with the Pennsylvania Department of Transportation as follows:
(a) 
An access management/site plan review committee that includes representatives of the Pennsylvania Department of Transportation and the Township shall review the application. The committee shall inform the developer what information will be required for access review. Information required of the applicant may vary depending upon the size and timing of the development, but shall at a minimum meet the requirements of this section.
(b) 
Upon review of the application, the access management review committee shall advise the Zoning Officer whether the access application is recommended for approval, approval with conditions, or denial.
(7) 
If the application is recommended for approval with conditions, the applicant shall resubmit the plan with the all recommended changes made. The revised plan, with submitted changes, will be reviewed by the Township within 60 days of resubmission and approved or rejected. Second applications may only be rejected if conditional changes are not made.
(8) 
If the access permit is denied, Unity Township shall provide an itemized letter detailing why the application has been rejected.
(9) 
Where applications are approved, approved with conditions, or rejected, any aggrieved party shall have 30 days to file an appeal in accordance with the provisions of the Pennsylvania Municipalities Planning Code (MPC).
P. 
Modification and waiver standards.
(1) 
Any modification or waiver of the standards contained in this article shall be in harmony with the purpose and intent of these regulations and shall not be considered until every feasible option for meeting the access standards of this section are found by the Township to be unfeasible.
(2) 
Applicants for a modification or waiver from these standards must provide proof of unique or special conditions that make strict compliance with the provisions of this chapter unfeasible. Such proof shall include evidence that:
(a) 
Indirect or restricted access cannot be obtained;
(b) 
No engineering or construction solutions can be applied to mitigate the condition; and
(c) 
No alternative access is available from a street with a lower functional classification than the primary roadway.
(3) 
No modification or waiver will be granted unless its denial would preclude the applicant all reasonable access, endanger public health, welfare or safety, or cause an exceptional and undue hardship on the applicant. No modification or waiver shall be granted where such hardship is self-created.
(4) 
The Township may reduce the connection spacing requirements set forth herein in situations where they prove impractical, but in no case shall the permitted spacing be less than 80% of the applicable standard unless a modification or waiver is granted pursuant to this section.
(5) 
Modification from the standards established in herein shall be permitted by the Township where the modification would enhance the safety or operation of the roadway. Such modifications may include, for example, a pair of one-way driveways in lieu of a two-way driveway, or alignment of median openings with existing access connections. Applicants may be required to submit a study prepared by a registered engineer to assist the Township in determining whether the proposed change would exceed roadway safety or operational benefits of the prescribed standard.
(6) 
New connections shall not be permitted within the functional area of an intersection or interchange as defined by the connection spacing standards of this code, unless:
(a) 
No other reasonable access to the property is available; and
(b) 
Following submission and review of a site-specific study of the proposed connection prepared by a registered engineer and submitted by the applicant, the Township determines the connection does not create a safety or operational problem.
(7) 
The Township may reduce the required separation distance of access points where they are impractical and where:
(a) 
Joint access driveways and cross-access easements are provided wherever feasible in accordance with this section.
(b) 
The site plan incorporates a unified access and circulation system in accordance with this section.
(c) 
The property owner enters a written agreement with the Township, to be filed of record with the Recorder of Deeds of Westmoreland County, that preexisting connections on the site will be closed and eliminated after construction of each side of the joint-use driveway.
(8) 
The Township may modify or waive the requirements for "joint and cross access" set forth herein where the characteristics or layout of abutting properties would make development of a unified or shared access and circulation system impractical.
(9) 
Modification of the general standards for driveway length or "throat length" as established in Appendix A, Figure 4,[5] shall be permitted for good cause upon approval of the Township.
[5]
Editor's Note: Appendix A is included as an attachment to this chapter.
(10) 
The frontage requirements established herein may be waived where access is internalized using the shared circulation system of the principal development or retail center.
A. 
Creation of districts. In order to protect against hazards to air navigation, there are hereby created and established certain Airport Zoning Districts (AZDs) which include all of the land lying beneath the approach surfaces, transitional surfaces, horizontal surfaces and conical surfaces as they apply to the Arnold Palmer Regional Airport. Such zones are visually depicted on the Height Limitation and Zoning District Map prepared January 2008 which is attached to this chapter, made a part hereof.[1] An area located in more than one of the following zones is considered to be only in the zone with the more restrictive height limitation. The Airport Zoning Districts are:
(1) 
AZD-1: Primary Surface Zoning District.
(2) 
AZD-2: Utility Runway Visual Approach Zoning District.
(3) 
AZD-3: Runway Larger than Utility with a visibility minimum as low as 3/4 mile Non-Precision Instrument Approach Zone (Runway 05).
(4) 
AZD-4: Precision Instrument Runway Approach Zone (Runway 23).
(5) 
AZD-5: Transitional Zoning District (adjacent to approach zoning districts).
(6) 
AZD-6: Horizontal Zoning District.
(7) 
AZD-7: Conical Zoning District.
[1]
Editor's Note: The Height Limitation and Zoning District Map is on file in the Township offices.
B. 
Height limitations. In all Airport Zoning Districts, no permit shall be required for any tree or structure less than 75 feet of vertical height above the ground, except when, because of terrain, land contour or topography's features, such tree or structure would extend above the height limits prescribed for such zones. Such height limitations are as follows:
(1) 
AZD-1: Appropriate runway type and dimension for the width of the primary surface is set forth in Federal Aviation Regulation Part 77, Objects Affecting Navigable Airspace, Dimensional Standards Table, Page 19, January 1975.
(2) 
AZD-2: Slopes 20 feet outward for each foot outward beginning at the end of and at the same elevation as the primary surface and extending to a horizontal distance of 5,000 feet along the extended runway center line.
(3) 
AZD-3: Slopes 34 feet outward for each foot upward beginning at the end of and at the same elevation as the primary surface and extending to a horizontal distance of 10,000 feet along the extended runway center line.
(4) 
AZD-4: Slopes 50 feet outward for each foot upward beginning at the end of and at the same elevation as the primary surface and extending to a horizontal distance of 10,000 feet along the extended runway center line, thence slopes upward 40 feet horizontally for each foot vertically to an additional horizontal distance of 40,000 feet along the extended runway line.
(5) 
AZD-5: Slopes seven feet outward for each foot upward beginning at the sides of and at the same elevation as the primary surface and the approach surface and extending to a height of 150 feet above the airport elevation, which is 1,161 feet above mean sea level.
(6) 
AZD-6: Either 150 feet above the airport elevation or 1,311 feet above mean sea level.
(7) 
AZD-7: 1,511 feet above sea level.
C. 
Electrical interference and glare. Notwithstanding any other provisions of this chapter, no use may be made of land or water within any zone established by this chapter in such a manner as to create electrical interference with the navigational signals or radio communication between the airport and aircraft; no lighting or sign shall be erected which might make it difficult for pilots to distinguish between airport lights and others or result in glare in the eyes of pilots using the airport; no use or structure shall create bird strike hazards or otherwise in any way endanger or interfere with the landing, takeoff or maneuvering of aircraft intending to use the airport.
D. 
Lights and marker on nonconforming structures. The owner of any nonconforming use or structure in an Airport Zoning District is hereby required to permit the installation, operation and maintenance of such markers and lights as shall be deemed necessary by the airport manager to indicate to the operators of aircraft in the vicinity of the airport the presence of such airport obstruction. Such markers and lights shall be installed, operated and maintained at the expense of the Westmoreland County Airport Authority.
E. 
Airport overlay district permits. In any Airport Zoning District, no permit shall be required for any tree or structure less than 75 feet of vertical height above the ground, except when terrain, land contour or topographic features would cause such tree or structure to extend above the height limits prescribed for such zones.
F. 
Existing uses. A permit shall be obtained before any existing use or structure may be substantially changed, but no permit shall be required to make maintenance repairs to or to replace parts of existing structures which do not enlarge or increase the height of the structure.
G. 
Variances. Any person desiring to increase the height of any existing or proposed structure or permit the growth of any object of natural growth or otherwise use his property in violation of this section shall apply to the Hearing Board for a variance.
H. 
Hazard marking and lighting. Any permit granted under the provisions of this section may be conditioned upon the installation of hazard markers and lighting as may be required by guidelines or regulations adopted by the Federal Aviation Administration of the United States.
I. 
Communications antennas. In Airport Overlay Districts, the following new uses by right are inserted: communications antennas mounted on an existing public utility transmission tower, building or other structure, including existing communications towers, and communications equipment buildings.
A. 
Nonresidential developments. In addition to all other applicable provisions of Chapter 118, Zoning, and this chapter, the following provisions shall apply to nonresidential land developments with frontage on State Route 30 in the Township.
B. 
Building orientation and design:
(1) 
Orientation. Any individual building developed on a lot shall be oriented to face State Route 30. For buildings developed as part of a multi-building development, orientation of some buildings may face a central plaza or parking area, provided that any wall facing the principal roadway shall meet all design standards specified below.
(2) 
Building materials. Every portion of any exposed exterior wall surface shall be composed of durable materials such as brick, stone, decorative split-face block, marble, glass or wood. Concrete block and corrugated metal shall be prohibited. The Board of Supervisors may approve alternative materials only if such materials are determined to be equal or superior to the materials described above.
(3) 
Building design:
(a) 
Building design shall complement surrounding buildings and reflect the character of the zoning district in which the building is located. The suitability of materials, architectural elements, features, and colors shall be determined in consultation with the Township.
(b) 
Buildings in multiple-building developments shall possess common design characteristics including, but not limited to, consistent rooflines, use of compatible proportions in building mass and outdoor spaces, complementary relationships to the street, similar window and door patterns, and the use of similar building materials in terms of color, shades and textures.
(c) 
No wall surface shall exceed 50 continuous feet without a break. A break shall consist of either (1) a recess or offset measuring at least 10 feet in depth or one-quarter of the building in length or (2) a series of recesses or offsets, at intervals of not more than 30 feet, each measuring a minimum of four feet in depth. The objective of this standard is to avoid large, undifferentiated wall surfaces.
(d) 
Buildings over 30 feet in height shall include architectural features that mimic two story structures, such as windows, cornices or similar components. Buildings with flat roofs shall have mansard roof facades or gabled roofs over the required offset areas.
C. 
Buffering and landscaping.
(1) 
Any development within the Corridor Enhancement Overlay shall meet the requirements for landscaping set forth in Chapter 118, Zoning, and this chapter.
(2) 
In addition, any development shall comply with the following requirements:
(a) 
All areas not utilized for structures, driveways, planting strips or parking facilities must be seeded, sodded or landscaped within a reasonable period of time. The phrase "a reasonable period of time" shall be interpreted to be within two weeks after construction activities are completed, unless those activities are completed between November 1 through April 1. In such case, the required sodding or seeding must occur within two weeks of April 1.
(b) 
A buffer-yard shall be created within the front setback measuring 25 feet in depth from the edge of the paved surface. Such buffer-yard shall create a visual screen between the road and the development. Plantings shall be consistent with those provided in Subsection C(2)(d) below and Chapter 118, Zoning.
(c) 
Any nonresidential development in the Corridor Enhancement Overlay District abutting a residential property shall install a fifty-foot wide buffer-yard extending the full length of the abutting residential property line.
(d) 
Within any such required bufferyard, the following plantings shall be required: for every 100 linear feet, a minimum of five large canopy trees, six understory or small canopy trees, 12 evergreen trees and 30 evergreen shrubs.
(3) 
Existing vegetation. Developments shall be encouraged to preserve trees and shrubs which exist within the required buffer-yard area of the development parcel. Existing trees and shrubs may be utilized to satisfy the required buffer area planting required herein; provided, however, that the performance standards regarding height and mix of types of plantings are met. In the event the existing trees and shrubs do not satisfy the buffer requirements, the applicant shall use new plantings in combination with the existing plantings to satisfy the buffer requirements.
(4) 
No structures or uses, including, but not limited to, buildings, accessory structures, parking spaces, curbs, access drives and lighting devices, may be located in any required bufferyard. No fences or screening walls shall be located facing Route 30, unless they are attached to the principle structure, be parallel to the front of the principle structure, do not encroach into any required setback and are used to define an outdoor sales area accessory to the use of the attached structure.
(5) 
In addition to the other requirements of this section, any nonresidential building in the Route 30 Corridor Enhancement Overlay District shall maintain those site distances established in § 118-44.E of Chapter 118, Zoning.
A. 
Purpose. To ensure compliance with the provisions of this section, all new construction or development incorporating an increase in the intensity or size of an existing use, or a change of use from a residential to a commercial, other than a home occupation, within the Village Commercial Overlay District shall be subject to conditional use approval and site plan review in accordance with the provisions of this chapter. Any exterior change to an existing building not incorporating an increase in the size or intensity of the use or a change in use may be approved administratively through the Unity Township Planning/Zoning Office.
B. 
Permitted uses subject to land development approval. Uses in this district may be permitted as conditional uses after making application according to the provisions of this chapter and Chapter 118, Zoning. Uses subject to land development must:
(1) 
Be complimentary to the spirit and purpose of the Village Overlay District;
(2) 
Be compatible with existing uses in the area;
(3) 
Not interfere with the orderly development of the area;
(4) 
Not be detrimental to the safety and convenience of vehicular and pedestrian traffic;
(5) 
Not be injurious to the Overlay District and its environs;
(6) 
Be served adequately by essential public facilities and services;
(7) 
Be consistent in assuring that the public health, safety, and welfare will be maintained;
(8) 
Be in compliance with Township, county, state, and federal laws, ordinances, rules and regulations.
C. 
Conditional uses. Applicants for development within the Village Commercial Overlay District may seek site plan approval and conditional use approval in a single proceeding. If such approval is sought, the applicant shall submit a site plan consistent with this chapter along with its application for conditional use approval. The Planning Commission and Board of Supervisors shall thereafter review and dispose of both requests concurrently. The mixing of residential uses with office and/or commercial uses is encouraged within the Commercial Village Overlay District. On any parcel within the Overlay District, the mixing of residential and nonresidential uses may be permitted by the Board of Supervisors as a conditional use subject to the following:
(1) 
All residential components of a mixed use project shall be located either above at least one story of a nonresidential use or to the rear of a nonresidential use building.
(2) 
Residential uses shall not be permitted on the ground floor unless they are located behind a nonresidential use.
(3) 
Required off-street parking shall be computed separately for each of the uses incorporated into the mixed use project.
(4) 
The primary public customer entrance to the nonresidential component of a mixed use development shall be oriented toward a street and shall provide direct pedestrian access to the street right-of-way or parking lot.
D. 
Site and architectural design standards.
(1) 
Screening. Screening shall not be generally required within the Village Overlay District, except when a nonresidential use or mixed use development is established adjacent to a residentially zoned or used property located outside of the Village Overlay District boundaries. Where required, a screen not less than six feet in height shall be erected along the common lot line. Screening treatments shall be subject to the review and approval by the Township.
(2) 
Landscaping. For lots not developed to 100% lot coverage within the Overlay District, site landscaping shall be designed in accordance with the following requirements:
(a) 
All permanently undeveloped portions of the site shall be planted with grass, ground cover, shrubbery, or other suitable live plant material, which shall extend to any developed pavement edge. Existing plant material on the property may be used.
(b) 
Foundation plantings are encouraged along the front or sides of any building which faces a public or private road, or is adjacent to a parking lot or other area which provides access to the building by the general public. Foundation planting areas should be integrated into any existing sidewalk system between the front or sides of the building and the parking area (and/or associated driveways) adjacent to the building.
(c) 
Landscaping within the Village Overlay District shall be maintained in a healthy, neat, and orderly appearance, free from refuse and debris. All unhealthy and dead plant material shall be replaced immediately unless the season is not appropriate for planting, in which case such plant material shall be replaced at the beginning of the next planting season. All constructed or manufactured landscape elements, including, but not limited to, benches, retaining walls, edging, and similar structures, shall be maintained in good condition and neat appearance. Rotted, deteriorated, dead, or damaged landscape elements shall be repaired or replaced.

A. 
Purpose. The creation of a Planned Residential Development is the creation of a separate and distinct zoning classification for the property for which treatment as a Planned Residential Development is sought and is designed to regulate the density or intensity of land use otherwise applicable to the land under the provisions of Chapter 118, Zoning, and this chapter. Planned Residential Developments may be allowed or denied by the Board of Supervisors after recommendation by the Planning Commission in accordance with the procedures set forth below.
B. 
Findings of fact. A development plan for a Planned Residential Development shall be approved if and only if it is found to meet the following criteria:
(1) 
Comprehensive Plan. The proposed development plan preserves the community development objectives of this chapter and is consistent with the Comprehensive Plan.
(2) 
Exceptions. Where the proposed development plan departs from zoning and subdivision regulations otherwise applicable to the subject property, any departure must be shown by the owner and/or developer to be in the public interest and promote the health, safety and general welfare of the public. Although the Board of Supervisors, following the procedures set forth in this chapter hereafter, may alter the density and other development regulations for the property by approving same as a Planned Residential Development, no such exception shall be made from the minimum acreage requirement for same. The formation of a Planned Residential Development is intended to create a separate and distinct community containing a mixture of uses and development intensities. Any Planned Residential Development containing less than the minimum required acreage is not deemed to serve, and is inconsistent with, the overall intent and purpose of the establishment of this zoning classification.
(3) 
Open space. The proposals for the maintenance and conservation of any proposed common open space are reliable and the amount and extent of improvements of such open space is adequate with respect to the purpose, use and type of development proposed.
(4) 
Infrastructure. The physical design of the proposed development plan adequately provides for public services, pedestrian and vehicle traffic facilities and parking, light, air, recreation and visual enjoyment.
(5) 
Neighborhood. The total environment of the proposed development plan is harmonious and consistent with the neighborhood in which it is located and that the long term development of any unused portion of the land owned or controlled by the developer will be harmonious and consistent with the portion of the land proposed for approval.
(6) 
Environment. The proposed development plan will afford a greater degree of protection of natural watercourses, topsoil, trees and other features of the natural environment and prevention of erosion, landslides, siltation and flooding than if subject property were developed in accordance with the provisions of the zoning and subdivision ordinances which otherwise apply.
(7) 
Safety. The proposed use shall not involve any element or cause any condition that may be dangerous, injurious or noxious to any property or persons and shall comply with the performance standards of this chapter, Chapter 118, Zoning, and all other applicable local ordinances, municipal rules or regulations, state and/or federal laws or other administrative agency requirements.
(8) 
Timing. In the case of a development plan which proposes development over a period of years, the development plan will provide at each stage of development a sufficient proportion of open space, planned facilities and amenities and other improvements and conditions as required in this article and as intended to protect the interests of the public and of the residents of the Planned Residential Development in the integrity of the development plan.
C. 
Required standards. Planned Residential Developments may be approved under the provisions of this chapter if, and only if, they comply with the following standards and provisions:
(1) 
Ownership. The entire site for the Planned Residential Development shall be owned or controlled by the developer.
(2) 
Minimum size. The site shall not be less than 10 acres in the R-1 or R-2 District.
[Amended 5-11-2017 by Ord. No. O-5-2017]
(3) 
Frontage. The minimum frontage abutting on a public right-of-way shall not be less than 200 feet.
(4) 
Access. The site must provide for access from existing or proposed roads which are adequate to assure convenient and safe access which will not cause undue congestion or hazard on local streets.
(5) 
Safety. The site shall be of such a character so as to avoid danger to health or peril from fire, flood or other hazard. Land containing or providing hazards to life, health and property, such as quarries, open ditches, land subject to flooding, subsidence, landslide-prone or underground fires shall not be subdivided for residential purposes until such hazards have been eliminated or adequate safeguards are provided under the development plan.
(6) 
Permitted uses. A Planned Residential Development shall include a combination of not less than two different types of residential uses, such as dwelling units in single-family detached, semidetached, townhouses, two-family residential facilities, three and four unit facilities, garden apartments, apartments or any combination thereof, as permitted and approved by the Township. Provided, however, that garden apartments, apartments or any combination thereof, shall not be permitted in any R-1 Zone. To the extent they are designed and intended to serve the residents of the Planned Residential Development, accessory and ancillary commercial recreational and institutional uses and buildings, such as clubhouses, pools and pool houses, may be permitted at the sole discretion of the Board of Supervisors.
[Amended 5-11-2017 by Ord. No. O-5-2017]
D. 
Underlying zoning. Planned Residential Developments shall only be permitted in those Zoning Districts where they appear as conditional uses.
E. 
Permitted density. The following density requirements shall apply to all PRDs:
(1) 
Gross density. The maximum allowable average gross residential density for Planned Residential Developments shall be not greater than four dwelling units per acre of land, No more ancillary commercial development shall be allowed than expert market analysis shows, to the satisfaction of the Township, will be needed to serve the resident population of the Planned Residential Development and any established residential developments within a one-half-mile radius of the Planned Residential Development. In calculating area for density purposes, any portion of the Planned Residential Development having a slope greater than 40% shall be subtracted from the total area, and 1/2 of any areas having a slope of 25% or more up to 40% shall be subtracted from the available area. For such calculations, the slope shall be measured between contours having vertical intervals no greater than 20 feet.
(2) 
Open space requirements. Not less than 35% of the site area shall be set aside for open space, and not less than 50% of such open space shall be developed for recreational purposes to a degree commensurate with its location and probable usage. Any portion of the Planned Residential Development having a slope greater than 25% or more shall be subtracted from the area calculated as available for common open space. For such calculation, the slope shall be measured between contours having vertical intervals no greater than 20 feet. The common open space shall be so dedicated or otherwise preserved and maintained so as to always remain open and available for use by the occupants of the Planned Residential Development. The common open space, including all improvements and facilities, shall be either:
(a) 
Dedicated for public use to a public body which agrees to operate and maintain the dedicated land and facilities, but no public body is obliged by this chapter to accept such dedication; or
(b) 
Deeded to an organization representing the property owners of the development, which shall covenant to operate and maintain such land and facilities. Such organization may not be dissolved nor dispose of the common open space unless the maintenance of the common open space is otherwise guaranteed to the satisfaction of the Board of Supervisors.
(3) 
Common open space maintenance responsibilities.
(a) 
If the organization established to own and maintain common open space or any successor organization fails to maintain such common open space in reasonable order and condition in accordance with the development plan, the Township may serve written notice upon such organization or upon the residents of the Planned Residential Development, setting forth the maintenance deficiencies, requiring correction of deficiencies within 30 days and stating the date and place of a hearing thereon which shall be held within 14 days of the notice. At such hearing, the Township may modify the terms of the original notice as to the deficiencies and may give an extension of time within which they shall be corrected. If the deficiencies so set forth shall not be corrected within the specified time limit, the Township, in order to preserve the taxable values of the properties within the Planned Residential Development and to prevent the common open space from becoming a public nuisance, may enter upon and maintain the common open space for one year. This maintenance shall not constitute a taking nor vest in the public any rights to use the common open space. Before the expiration of the year, the Board of Supervisors shall set a public hearing where such organization or residents of the Planned Residential Development may show cause why maintenance by the Township should not continue for any other year. If the Board of Supervisors determines that such organization is ready and able to maintain said common open space in reasonable condition, the Township shall cease to maintain said Common open space at the end of said year. If the Board of Supervisors shall determine that such organization is not ready and able to maintain said common open space in a reasonable condition, the Township may, in its discretion, continue to maintain said common open space during the next succeeding year and, subject to a similar hearing and determination, in each year thereafter.
(b) 
The cost of such maintenance by the Township shall be assessed ratably against the properties within the Planned Residential Development that have a right of enjoyment of the common open space and shall become a lien on said properties. The Township, at the time of entering upon said common open space for the purpose of maintenance, shall file with the county a notice of lien upon properties affected. The Township may enforce or collect any amounts subject to such lien in any manner prescribed by law, this chapter or Chapter 118, Zoning.
(4) 
Minimum building setback. No structure shall be located closer to any boundary of the site than 40 feet. Any structure exceeding 35 feet in height shall be set back one additional foot for every two feet of height exceeding 35 feet.
(5) 
Building spacing. The requirements determining the spacing of buildings shall be as flexible as possible so as to encourage imaginative site design. The spaces between buildings shall guarantee adequate light, air and emergency access. The minimum distance between the nearest points of any exterior building walls shall not be less than 20 feet.
(6) 
Maximum size of structure. No structure shall have a maximum dimension (i.e., a front, side or rear wall) greater than 250 feet. No townhouse shall have a height greater than three stories or 35 feet. No apartment shall have a height greater than three habitable stories or 35 feet. Chimneys, spires, towers, tanks or similar projections may exceed the prescribed height limitation by not more than 25%.
(7) 
Building groupings. Structures used for dwelling units shall be oriented so as to ensure adequate light and air exposures for walls containing main window exposures or main entrances. Each structure shall be so arranged so as to avoid undue exposure to concentrated loading or parking facilities.
(8) 
Staging development. The density of development within various portions of the Planned Residential Development may vary, provided that each such area or portion of the development plan meets all requirements of this chapter. It is further required that programs for the construction of areas of greater density concentration than permitted on the entire tract will be offset by site improvements which, because of their size or cost, are in proportion to the number of dwelling units to be constructed in each stage. As an alternative to part or all of the site improvements required to offset development densities in excess of the overall permitted density, the Township may require the reservation of open space by grant, easement or covenant in favor of the Township in an amount and location necessary to balance the excess development density of each stage.
F. 
Required improvements. The following improvements shall be completed in connection with every Planned Residential Development.
(1) 
Off-street parking spaces shall be provided in accordance with the provisions of Chapter 118, Zoning, for each proposed use, building or structure.
(2) 
Areas should be provided for bus loading areas and bus shelters within 1/4 mile of each residential concentration. The bus loading area shall be large enough for a bus to pull out of the flow of traffic.

Proposed streets shall conform to the requirements herein as well and as to any other plan, statute, ordinance, law or regulation applicable thereto. Streets shall be logically related to the topography in order that usable lots and reasonable grades shall be produced. Minor streets shall be so laid out as to discourage through traffic, but provisions will be required for street connections into and from adjacent areas.
(5) 
Where a Planned Residential Development abuts or contains an existing or proposed major traffic street, the Board of Supervisors may require marginal access streets, rear service alleys, reverse frontage lots or such other treatment as will provide protection for abutting properties, reduction in the number of intersections with major streets and separation of local and through traffic.
(6) 
Suitable drainage structures, culverts, storm sewers, ditches and related installations shall be provided to ensure adequate drainage of all points along the streets.
(7) 
Concrete monuments shall be set at the intersection of all lines forming angles in the boundary of the Planned Residential Development.

(8) 
Pedestrian interior walks may be required where necessary to assist circulation or provide access to community facilities. Such interior walks shall have a paved width of not less than five feet and comply with the provisions of the Americans With Disabilities Act, as amended and existing at the time any application is finally approved by the Township.
(9) 
When topsoil has been removed from the surface on a slope where erosion may cause a displacement of loose material, the area shall be seeded or otherwise treated as soon as possible to prevent damage to adjacent property or streets.
(10)

If water is to be provided by means other than by private wells owned and maintained by the individual owners of lots within the planned development the developer shall present evidence to the Board of Supervisors that the planned development is to be supplied by a certificated public utility, a bona fide cooperative association of lot owners or by a municipal corporation, authority or utility. A copy of a certificate of public convenience from the Pennsylvania Public Utility Commission or an application for such certificate, a cooperative agreement or a commitment or agreement to serve the area in question, whichever is appropriate shall be acceptable evidence.
G. 
Guaranty of improvements. No permit may be issued for any construction of any home or structure within a PRD, unless all improvements required by the Township have been installed in accordance with Township specifications or unless Financial Security in the form of a bond, a letter of credit or deposit of funds or securities in escrow, acceptable to the Board of Supervisors, ensuring that the improvements will subsequently be installed by the developer is posted in an amount sufficient to cover the cost of the improvements which may be required plus 10%. Such bond or other security shall provide for and secure to the public the completion of all declared improvements within a period of one year from the date of final approval of the plan. Such guaranty of improvements shall comply with Section 509 of the Pennsylvania Municipalities Planning Code.[1]
