A. 
Existing parking. Structures and uses in existence at the date of adoption of this chapter shall not be subject to the requirements of this article so long as the kind or extent of use is not changed, provided that any parking facility now serving such structures or uses shall not in the future be reduced below such requirements.
B. 
Conflict with other uses. No parking areas shall be used for any use that interferes with its availability for the parking need it is required to serve.
C. 
Joint use. Two or more uses may provide for required parking in a common parking lot if the total space provided is not less than the sum of the spaces required for each use individually. However, the number of spaces required in a common parking facility may be reduced below this total by special exception if it can be demonstrated to the Zoning Hearing Board that the hours or days of peak parking needed for the uses are so different that a lower total will provide adequately for all uses served by the facility.
D. 
Where any parking spaces are subject to and in conformity with multiple uses as described in § 230-32 generally, that use requiring the most restrictive amount of parking spaces will control the provision of parking spaces for the multiple use area.
E. 
Location of parking spaces. Required off-street parking spaces shall be on the same lot or premises with the principal use served; or, where this requirement cannot be met, within 300 feet of the required off-street parking.
F. 
Parking space size.
(1) 
In all residential, office, and industrial districts the size of each parking space shall be no less than nine feet in width by 20 feet in length.
(2) 
In all commercial districts the size of each parking space shall be no less than 10 feet in width by 20 feet in length.
(3)

In order to prevent a greater number of parking spaces than is actually required to serve the needs of nonresidential uses, the Township Council, after consulting with the Planning Commission and Township Engineer, may permit a conditional reduction of parking space if the following conditions are satisfied:
A. 
The design of the parking lot, as indicated on the land development plan, must designate sufficient space to meet the parking requirements of this chapter. The plan shall also illustrate the layout for the total number of parking spaces.
B. 
The conditional reduction shall provide for the establishment of not less then 80% of the required number of parking spaces, as specified in this chapter. This initial phase of the parking provision shall be clearly indicated on the plan.
C. 
The balance of the parking area conditionally reserved shall not include areas for required buffer yards, setbacks, or areas which would otherwise be unsuitable for parking spaces due to the physical characteristics of the land or other requirements of this chapter. This parking area which is reserved shall be located and have characteristics so as to provide amenable open space should it be determined the additional parking spaces are not required. The developer shall provide a landscaping plan for the reserved area with the land development plan.
D. 
The developer shall enter into a written agreement with the Township that the additional parking spaces shall be provided at the developer's or owner's expense should it be determined that the required number of parking spaces are necessary to satisfy the need of the particular land development.
E. 
At the time of the above stated agreement, the developer or owner shall post a performance bond or other securities to cover the expense of a traffic study to be undertaken by a registered traffic engineer of the Township's choosing who shall determine the advisability of providing the full parking requirement. The bond shall also include the estimated cost of the installation of the parking spaces. If the study determines the spaces are not needed, this money shall be refunded. Said study shall be undertaken one year after the issuance of the last occupancy permit pursuant to Subsection D above. With the recommendations of the traffic engineer, the Township Engineer, and the Planning Commission, the Township shall determine if the additional spaces shall be provided by the developer or if the area shall remain as open space.
F. 
Land which has been determined and designated by the Township to remain as open space rather than as required parking shall not be used to provide parking spaces for any building addition or expansion but shall remain as open space.
Adequate off-street loading and unloading space with proper access from a street, highway, or common service driveway shall be provided on any lot on which a building or buildings used for commercial, business, industrial, or an institution, apartment house, or similar use is located. All areas for loading and unloading of delivery trucks and other vehicles and for the servicing of establishments or shops by refuse collection, fuel, and other service vehicles shall have adequate and unobstructed access from a street or service driveway and shall be so arranged that they may be used without blocking or otherwise interfering with the use of automobile access ways, parking facilities, or pedestrian ways. They shall also be so arranged that they may be used without backing out onto a street.
A. 
For industrial uses, there shall be one loading berth for the first 15,000 square feet of gross floor area and one additional loading berth for each subsequent 12,000 square feet of gross area or fraction thereof. Each loading space shall be not less than 14 feet by 65 feet in area and may occupy all or any part of any required side or rear yard except that portion which is required to be used for buffer areas.
B. 
For commercial and business uses, adequate off-street parking for the loading and unloading of goods and material shall be provided in accordance with the size and proposed use of the building. Each off-street loading space required in these areas shall be a minimum of 12 feet by 35 feet in area. The number and adequacy of such loading and unloading spaces shall be determined by the Township Council at the time of development plan approval upon consideration of the following factors:
(1) 
Ingress and egress to an adjacent street, alley or driveway;
(2) 
Location in relation to vehicular circulation in adjacent areas; and
(3) 
The nature of the establishment and its required schedule of loading and unloading.
In order to minimize traffic congestion and hazard, control street access in the interest of public safety, and encourage the appropriate development of street or highway frontage, no parking lot or area for off-street parking or for the storage or movement of motor vehicles shall abut directly a public street or highway unless separated from the street or highway by a raised curb, barrier planting strip, wall, or other effective barrier against traffic, and each parking lot shall have not more than two accessways to any one public street or highway for each 500 feet of frontage. Where possible, access to parking areas shall be provided by a common service driveway or minor street in order to avoid direct access on a major street or highway. No such accessway shall be more than 35 feet in width excluding any medial area. No accessway shall be less than 12 feet in width. When the applicant can demonstrate the increased width improves accessway safety, the accessway may exceed 35 feet in width in commercial, industrial, and office/nonmanufacturing districts. Points of vehicular egress or ingress shall be at least 100 feet in I-3 and all commercial districts except C-1 Districts; at least 300 feet in the I-2 District; and at least 500 feet in C-1, I-1 and O-1 Districts.

In any event, points of egress and ingress shall be reviewed by the Planning Commission and established to maximize public safety.
Parking spaces shall be provided for the physically disabled in accordance with all Commonwealth of Pennsylvania and federal standards. Each space shall have a width of not less than 12 feet.
The following regulations shall govern parking and circulation within lots to be developed in the commercial, office, and industrial districts, and shall also govern on lots to be redeveloped in the district to the maximum extent feasible:
A. 
For double parking bays, 15% of the area of each parking space may be maintained in grass or plantings, provided that the area is separated from the paved area by a curb or bumper.
B. 
The owners of two or more adjacent lots may elect to share common parking facilities according to the following requirements:
(1) 
An application to do so shall be filed jointly by all affected lot owners with the Zoning Officer accompanied by a plan showing the location of all proposed parking, parking reserved areas, and accessways as well as all buildings which shall use the common parking area.
(2) 
The aggregate number of parking spaces required for all uses which will share the common parking area may be reduced up to a maximum of 25% if the applicant can demonstrate to the Zoning Officer's satisfaction that a greater efficiency is effected by joint use of a common parking area, or that other circumstances warrant such reduction (i.e., complementary operating hours of the uses which will be sharing the parking area). Regardless of the number of spaces actually developed, a parking area to accommodate the aggregate number of parking spaces normally required shall be fully designed as required in § 230-34C and F, and the area which is proposed to be eliminated shall be shown as "parking reserve area." Such area shall be required to be developed as designed if and when the Zoning Officer determines the need. The parking reserve area shall be so designed that the minimum area of vegetative cover will not be reduced below the percentage required by the zoning district in which located in the event the entire parking area, including reserve areas, is subsequently developed. All parking reserve areas shall be landscaped according to an approved plan.
(3) 
For purposes of determining the number and location of accessways, the entire area devoted to common parking shall be considered as one parking lot.
(4) 
Some portion of the common parking area shall be within 200 feet of an entrance, regularly used by patrons, into each use served by the common parking area.

[Added 9-16-1998 by Ord. No. 1147]
A. 
In addition to the legislative intent of § 230-2, and in order to implement the objectives of the Horsham Township Comprehensive Plan and the Horsham Township Open Space Plan, the primary purpose of this section is as follows:
(1) 
To recognize that many undeveloped parcels in Horsham Township contain significant amounts of environmentally sensitive resources including floodplains, slopes, wetlands, streams, and woodlands.
(2) 
To recognize that disturbance of these environmentally sensitive resources results in negative impacts to the public health, safety, and welfare by causing greater erosion, siltation and sedimentation, flooding, degradation of water quality, and other adverse effects on the environment
(3) 
To reduce the amount of nutrients, sediment, organic matter, pesticides, and other harmful substances that reach watercourses, wetlands, subsurface, and surface water bodies.
(4) 
To promote, protect and facilitate proper density of land use based on a site's capacity; the provisions of adequate light and air; the provision of a safe, reliable and adequate water supply for domestic, commercial agricultural or industrial use; the preservation of the natural, scenic, and historic values in the environment; and the preservation of forests, wetlands, aquifers, and floodplains.
(5) 
To require protection of environmentally sensitive features to the greatest extent possible by minimizing disturbance of these areas.
(6) 
To conserve natural features important to protect natural resources; recognizing that headwater areas are highly sensitive to disturbance from the impact of human activity.
B. 
Density determination.
(1) 
The determination of density or intensity of land use shall apply to any subdivision or land development for any use, and include any site that contains any protected area.
(2) 
The disturbance standards described in this section shall apply to all uses and activities established after the effective date of this chapter. Site alterations, regrading, filling, or clearing of any natural resources, not expressly permitted within this chapter, are prohibited; provided that nothing in this section shall prohibit agricultural and forestry uses permitted by Act 133 of 1982 (Right to Farm Law).[1]
[1]
Editor's Note: See 3 P.S. § 951 et seq.
(3) 
In the event that two or more resources overlap, the resource with the greatest protection standard shall apply.
(4) 
Determination of density and intensity of use.
(a) 
The site's base site area shall be determined by subtracting all existing and proposed public and private road and utility rights-of-way, and land shown on previously approved subdivision or land development plans as reserved for open space from the total site area.
(b) 
The site's protected area shall be determined by calculating various environmentally sensitive areas, multiplying them by their respective open space ratio, and totaling the acreage to obtain the protected area as shown below:

NOTES:
1Any application for subdivision or land development of a tract which is first filed after the effective date of this subsection will be cumulative for the purpose of determining whether this exemption applies. If a property which benefits from this exemption is further subdivided, the woodland regulations shall be imposed retroactively, and Council may require reforestation of areas cleared.
(c) 
A site's developable area shall be determined by subtracting the protected area from the base site area.
(d) 
The maximum number of lots on a site is determined by taking the site's developable area and dividing it by the applicable lot area for the zoning district in which the site is located. For districts where density determines yields, the permitted density shall be determined by taking the site's developable area and multiplying it by the applicable number of units per acre.
C. 
Steep slope regulations.
(1) 
No areas of steep slopes shall be used without full compliance with the terms of this section.
(2) 
Slopes of 25% or greater.
(a) 
Slopes of 25% or greater shall not be altered, regraded, cleared, built upon or otherwise disturbed unless such disturbance is necessary to:
[1] 
Accommodate a street, driveway, or utility line when no other feasible route for such an activity exists, and if the slope disturbance is minimized to the greatest extent feasible to accommodate such activity; or
[2] 
Accommodate a trail or trails that are part of an existing or planned trail network, and are located and constructed based on accepted best management practices for minimizing erosion.
(b) 
In no case shall more than 20% of land with slopes of 25% or greater be disturbed.
(3) 
No more than 30% of the area of slopes greater than 15% but less than 25%, shall be altered, regraded, cleared, built upon, or otherwise disturbed.
(4) 
Methodology. Steep slopes shall be determined by measuring those areas of slope on a site over three or more two-foot contour intervals. Steep slope areas of less than 1,000 square feet of contiguous land, not abutting other areas of steep slope may be excluded in determining areas of steep slope.
(5) 
The Township shall exempt for man-made slopes (e.g., man-made slopes within a street right-of-way) from the provisions herein, if it is determined that alteration, regrading, clearing, construction upon such slopes will not be injurious to the health, safety and welfare of the community. It shall be the burden of the applicant to demonstrate that the steep slopes were man-made.
(6) 
The disturbance standards described in this section shall apply to all uses and activities established after the effective dated of this chapter, provided that residential accessory uses will be permitted on steep slopes on residential lots in existence of the effective date of this chapter.
D. 
Wetland protection standards.
(1) 
Wetland delineation. Wetlands shall be defined in accordance with the standards specified in the definition of wetlands. In the event the standard for determination of a wetland accepted by the U.S. Army Corps of Engineers conflicts with that accepted by the Pennsylvania Department of Environmental Protection, or the Environmental Protection Agency, the more restrictive standard shall be used in delineating wetland areas.
(2) 
If, after examination of the site by a wetlands specialist, wetlands are found to exist, a wetlands delineation study shall be prepared by a wetlands specialist, and copies of this study (including reports, maps, and field logs) shall be submitted by the property owner to the U.S. Army Corps of Engineers for certification and to the Township and Township Engineer for review. The Township shall have the right to inspect the site as part of its review of the wetlands delineation report. If, after examination of the site, it is determined that wetlands are not located on the site, all subdivision, and land development plans, submitted to the Township must contain the following note, signed and sealed by a wetlands specialist: "I hereby certify that no wetlands exist on this site."
(3) 
Wetland delineations shall be performed by wetlands specialists to include those persons being certified professional soil scientists as registered with the Registry of Certified Professionals in Agronomy Crops and Soils (ARCPACS); or as contained on consultant's list of Pennsylvania Association of Professional Soil Scientists (PAPSS); or as registered with the National Society of Consulting Soil Scientists (NSCSS), or as certified by state and/or federal certification programs; or by a qualified biologist/ecologist.
(4) 
Wetlands shall not be altered, regraded, developed, filled, piped or diverted, or built upon. In the event the property owner demonstrates to the Township's satisfaction that there is no alternative, minor road crossings, utility line crossings, streambank rehabilitation, and endwalls may be permitted.
(5) 
Wetland transition area.
(a) 
In order to minimize the adverse impacts of human activity; to prevent groundwater contamination; to reduce surface run-off and sedimentation; to protect the hydrology of the wetland; and to protect wildlife habitats, a wetland transition area shall be established. This transition area shall be established as a buffer extending from the outer limit of the wetlands as defined in this chapter a distance of 25 feet, or the extent of hydric soils extending beyond the wetland boundary, whichever is greater. Where sensitive site features warrant additional protection, the wetland transition area shall be extended in accordance with the most restrictive of the following conditions:
[1] 
Where the 300 feet of land adjacent to the outer limit of the wetlands has an average upland slope in excess of 10%, the wetland transition area shall be increased by four feet for each degree of slope above 10%, however, in no case shall the wetland transition area exceed 50 feet.
[2] 
Where a herbaceous vegetational community exists on land adjacent to the outer limit of the wetlands, the transition area shall be extended to not less than 50 feet.
[3] 
Where a scrub-shrub vegetational community exists on land adjacent to the outer limit of the wetlands, the transition area shall be extended to not less than 40 feet.
[4] 
Where a forested vegetational community exists on land adjacent to the outer limit of wetlands, no additional transition area is required.
(b) 
Where in the opinion of the Township, disturbance to the shape, but not the square footage, of a wetland transition area on a tract or parcel of land will result in minimal environmental impact and the modified transition area continues to serve the transition function, the wetland transition area may be reduced to 50% of its required width, so long as it is compensated by increasing the transition area width in another wetland transition area on the same site, and the total required wetland transition area square footage is not reduced.
(6) 
The following activities are permitted in wetland transition areas:
(a) 
Normal property maintenance such as mowing, pruning, and planting of native vegetation, subject to compliance with the restrictions listed in Subsection D(7).
(b) 
Streets and driveway crossings, if no feasible alternative alignments are available, and the crossing does not disturb more than 0.1 acre (1/10 of an acre) of the transition area within the tract or parcel.
(c) 
Underground utilities, if no feasible alternative alignments are available.
(7) 
Wetland transition areas are restricted from the following activities:
(a) 
Removal, dumping, filling, excavation, or disturbance of the soil, other than in association with any activities identified in Subsection D(6) hereof.
(b) 
Erection of structures or paving, other than in association with any activities identified in Subsection D(6) hereof.
(c) 
Destruction of plant life which would alter vegetation patterns.
(8) 
Any property containing wetlands shall have included in their deed for the individual lots, or parcel, a deed restriction filed with the Montgomery County Recorder of Deeds, requiring that the wetland areas depicted on the approved subdivision or land development plan shall be maintained as wetlands in perpetuity by the owners of the land.
(9) 
The disturbance standards described in this section shall apply to all uses and activities established after the effective date of this chapter, provided that residential accessory uses will be permitted in wetland transition areas on residential lots in existence as of the effective date of this chapter.
E. 
Riparian corridor preservation.
(1) 
Establishment. The establishment of the Riparian Corridor Conservation District (RCCD) applies to The Stream Valley Network, Figure 5,[2] identified in the Horsham Township Open Space Plan of 1995, including all tributaries, perennial and intermittent streams leading to those streams shown in Figure 5, and including all lakes and ponds.
[2]
Editor's Note: Figure 5 is on file in the Township offices.
(2) 
A residential lot legally in existence as of the effective date of this chapter, may expand the area of the principal building on the lot by not more than 25% of the ground floor area of the principal building on the property as of the effective date of this chapter without the provisions of the RCCD being applicable.
(3) 
Measurement of the RCCD boundary shall extend a minimum of 75 feet from each defined edge of an identified watercourse or surface water body at the top of the bank, or shall equal the extent of the one-hundred-year floodplain, whichever is greater. The district will consist of two distinct zones designated as:
(a) 
Zone One.
[1] 
This zone will begin at each edge of an identified waterway (which can include wetlands and intermittent watercourses) and occupy a minimum width of 25 feet measured horizontally on a line perpendicular to the top of bank. The width of Zone One may be required to extend beyond the minimum 25 feet depending upon existing topography, woodlands, and other natural conditions.
[2] 
Where steep slopes (in excess of 25%) are located within 25 feet of a Township designated watercourse, Zone One shall extend the entire distance of this sloped area. If the distance of this sloped area is greater than 75 feet, there will be no requirement for the establishment of Zone Two. If the distance is less than 75 feet, the width of Zone Two will be adjusted so that the total corridor width (Zone One and Zone Two) will be 75 feet maximum.
(b) 
Zone Two. This zone will begin at the outer edge of Zone One and occupy a minimum width of 50 feet in addition to Zone One, unless modified herein.
(c) 
Where the one-hundred-year floodplain extends greater than 75 feet from the waterway, Zone One shall remain a minimum of 25 feet wide, and Zone Two shall extend from the outer edge of Zone One to the outer edge of the one-hundred-year floodplain.
(d) 
Width determination. The developer, applicant, property owner or designated representative shall be responsible for the initial width determination of the riparian corridor and identifying this area on any plan that is submitted to the Township for subdivision, land development, or other improvements that require plan submissions or permits. This determination shall be subject to review by the Township Engineer.
(4) 
Uses permitted in the RCCD. The following uses are permitted, either by right or as a conditional use in the RCCD:
(a) 
Zone One.
[1] 
Uses permitted by right. Open space uses that are primarily passive in character shall be permitted to extend into the area defined as Zone One, including:
[a] 
Wildlife sanctuaries, nature preserves, forest preserves, fishing areas, passive areas of public and private parklands, and reforestation.
[b] 
Streambank stabilization.
[c] 
Corridor crossings by livestock.
[d] 
Property owners are permitted to remove trees as part of normal property maintenance so long as not more than 1,000 square feet of lot area is disturbed.
[2] 
Uses permitted by conditional use.
[a] 
Corridor crossings of recreational trails, roads, railroads, centralized sewer and/or water lines, and public utility transmission lines.

(b) 
The developer, applicant or property owner shall submit to the Township Engineer, a corridor management plan prepared by a landscape architect, engineer, or other qualified professional, which fully evaluates the effects of any proposed uses on the Riparian Corridor Conservation District when subdivision or land development is proposed for a property. The corridor management plan shall identify the existing conditions (vegetation, one-hundred-year floodplain, soils, slopes, etc.), all proposed activities, and all proposed management techniques, including any measures necessary to offset disturbances to the Riparian Corridor Conservation District. The plan shall be approved by Township Council as part of the subdivision and land development process.
(c) 
Vegetation selection. To function properly, dominant vegetation proposed to be planted in the corridor management plan shall be selected from a list of plants most suited to the riparian corridor. Plants not included on the lists may be permitted when evidence is provided from qualified sources certifying their suitability.
[1] 
In Zone One, dominant vegetation shall be composed of a variety of native riparian tree and shrub species and appropriate plantings necessary for streambank stabilization.
[2] 
In Zone Two, dominant vegetation shall be composed of riparian trees and shrubs, with an emphasis on native species and appropriate plantings necessary to stabilize the soil.
[3] 
Disturbed areas shall be revegetated with riparian corridor plants, in compliance with an approved corridor management plan.
[4] 
Areas that cannot be revegetated shall be restored in compliance with an approved corridor management plan.
(8)
