[Ord. 331, 11/17/1999, § 3.100]
1. 
The Zoning Map, which shows graphically the edges of all the zoning districts and identifies each by name, is an integral part of this chapter. Copies may not represent the current status of all zoning boundaries or districts.
2. 
The Official Zoning Map shall be kept in the Township Office and shall be updated by the Township Secretary immediately after any amendment affecting zoning boundaries or districts has been adopted by vote of the Board of Supervisors in accordance with the requirements of this chapter. The Official Zoning Map shall supersede any copies of the Zoning Map when disputes arise over boundaries or districts.
3. 
The Official Zoning Map shall bear the signatures of the Chairman of the Board of Supervisors and Secretary of the Township, as well as the date of adoption and ordinance number.
4. 
The Zoning Map shall only be amended by official action of the Board of Supervisors at an advertised meeting, after public hearing. Any revisions to the map not following Board action shall be a violation of this chapter and a civil offense (see § 27-1204).
5. 
The Zoning Map shows district boundaries as accurately as possible considering the map's scale. Boundaries that appear to follow roads, streams, railroads or property lines shall be construed to follow the center lines of such features or be coterminous with a property line. Where zone district boundaries are dimensioned by reference to a road, stream, railroad or property line, they shall be construed as dimensioned from the feature center line or property line.
6. 
Where disputes arise over the exact location of a zoning boundary, the Zoning Officer shall make the initial determination, using the rules outlined above and a field visit to the location in question. If either or both parties to the dispute disagree with the Zoning Officer's ruling, it may be appealed to the Zoning Hearing Board.
[Ord. 331, 11/17/1999, § 3.200]
1. 
The regulations governing development in a zone district shall apply uniformly to every proposed development in that zone district.
2. 
No building, structure or land area shall, after the adoption of this chapter, be erected, used or altered unless in conformance with the regulations of the zone district containing the property to be developed unless a variance has been granted by the Zoning Hearing Board allowing specific modifications of the regulations for the proposed development.
3. 
No yard or lot area shall be reduced in size or dimension so as to be less than the minimums prescribed for the zone district where such yard or lot is located. No yard or lot area or off-street parking space required by one building, structure or land use shall be claimed by another building, structure or land use.
4. 
Within each zone district, lands, buildings, and structures shall be used, and buildings and structures shall be erected, altered or enlarged only for any of the uses permitted by right in the particular zone district in which such buildings, structures, and lands are located.
5. 
When a use that is not specifically listed in any zone district is proposed for a particular location, the developer may either:
A. 
Allege that the use is covered within the definition of a permitted conditional or special exception use already included for the zone district where he/she hopes to build and ask the Zoning Officer for a decision appealable to the Zoning Hearing Board.
B. 
Propose an amendment to this chapter for action by the Planning Commission and Board of Supervisors that would add the use in question to those that are permitted by right or by conditional or special exception use in the zone district where the development is proposed.
6. 
Zoning of Land Annexed by the Township.
A. 
Any land annexed by the Township after the adoption of this chapter shall be placed, from the date of annexation, in the R-1 Residential Zone District.
B. 
Within a reasonable time after annexation, the Planning Commission shall prepare and submit to the Board of Supervisors, a report of its recommendations for the most appropriate zoning classification of the annexed land.
C. 
The Board shall submit the report to the County Planning Commission for review and comment and shall schedule a public hearing, following the same procedures as for any other amendment of this chapter.

Description of Each Zone District.
A. 
R-1 Residential Zone. Within the R-1 Zone District lie most of the steep slopes rising from the stream valleys in the rugged western half of the Township. There are developable plateaus at the top of these slopes, but access to them is difficult. The terrain and access suggest low density and planned residential development. Certain uses requiring large tracts, such as cemeteries and nursery plant raising, are also appropriate in this district.
B. 
R-2 Residential Zone. The boundaries of the R-2 Zone District enclose a large area in the northeast corner of the Township which is partly developed within medium sized lots. The area has good road access to the Route 28 Expressway and to Freeport Road via Little Deer Creek Road, and public utilities are available. Quarter acre lots, some institutions and planned residential developments are compatible in this zone.
C. 
R-3 Residential Zone. The R-3 zone district comprises the three almost fully developed and dense communities of Acmetonia, Chapel Downs and Denny Camp. Lots are small (some less than 5,000 square feet), homes are older (except for Chapel Downs, they predate World War II) and there is a strong sense of community and containment. Community facilities occur in this zone as well as a variety of housing types, but predominantly single-family dwellings. All utilities are available throughout the R-3 Zones which are close to major highways. Multifamily housing is appropriate for available sites in this zone district.
D. 
C-1 Neighborhood Commercial Zone. The majority of C-1 Zone District is characterized by businesses on small lots along the eastern and western segments of Freeport Road, which is Harmar's Main street. A wide range of small businesses serve and are handy to the neighborhood shopping and service needs of Harmar residents. Another neighborhood zone serves Harmar Heights and two others, largely undeveloped, are located on the northern part of Route 910.
E. 
C-2 Regional Commercial Zone. The C-2 Zone District is the regional business center of the lower Allegheny Valley, lying between the Turnpike, the Route 28 Expressway and Freeport Road. Heavy traffic interchanging these routes and going to and from the various major destinations that front Freeport Road characterize the district. The properties are large, with buildings set within parking areas that may account for two-thirds of each property. A variety of retail, service, entertainment, transportation and traveler facilities are found in the area, which is well insulated by hillsides, railroads and major transportation arteries from residential development.
F. 
C-3 Regional Commercial Zone. The C-3 Zone District is an adjunct to the C-2 Zone that takes advantage of its proximity to the interchange of the Route 28 Expressway and Route 910. The commercial and business uses permitted in C-3 are nearly identical to those allowed in C-2. Development within C-3, however, will require extensive earth movement to create building sites because of the steep slopes prevalent in the zone. Some properties might be developed as a group of sites at different elevations to reduce grading and maximize land utilization. Stormwater management and traffic circulation to and within the sites are of critical importance.
G. 
I-1 General Industrial Use. The I-1 Zone is the largest in the Township but includes substantial areas of wetlands in the Deer Creek Valley. The industrial parks between Little Deer Creek Road and the Bessemer and Lake Erie Railroad, the three large corporate research centers and land between the Turnpike and Route 910 in the northern part of the Township are all zoned I-1. Good rail and truck access are available at the Little Deer Creek Road sites and good truck access at the other locations.
H. 
The R-T District is characterized by properties that were previously zoned residential, but which border or are in close proximity to an Industrial District and have been used for many years for nonresidential purposes. These properties, as a contiguous district, are properly viewed, due to their nonresidential history and the present existence of nonresidential buildings thereon, as "transitional areas" where a mix of residential and nonresidential uses, including some available in nonresidential districts, may be accommodated. Nonresidential uses are limited in number and operational impact to coexist more harmoniously with nearby residential uses.
