A. 
Standard to be applied. The design standards and requirements outlined in this article will be applied by the Planning Commission in evaluating plans for all proposed subdivisions.
B. 
Minimum provisions. These standards and required improvements are recommended as minimum provisions.
A. 
Land requirements.
(1) 
Land shall be suited to the purpose for which it is to be subdivided. Land subject to periodic flooding or other hazards to life, health or property shall not be subdivided unless adequate safeguards against such hazards are provided by the plan.
(2) 
In determining the suitability of land for subdivision, the Planning Commission may refer to applicable studies completed of the county, prepared by competent state and federal agencies, including but not limited to the Soil Survey Report prepared by the United States Department of Agriculture, Soil Conservation Service or their own sources.
B. 
Community facilities and Comprehensive Plan requirements. The Commission will consider the adequacy of the existing or proposed community facilities to serve the uses proposed in the subdivision. Where a proposed park, playground, school or other public use shown in the Comprehensive Plan is located in whole or in part in a subdivision, the Commission may require the provision or reservation of such area as may be deemed reasonable (normally considered to be about 5% of the gross area of the subdivision).
(1) 
Areas provided or reserved for such community facilities should be adequate to provide for building sites, landscaping and off-street parking as appropriate to the use proposed.
(2) 
The layout of the proposed subdivision shall be in general conformity with the features or developments proposed in the Comprehensive Plan.
(3) 
Suitable arrangements shall be made for fixing responsibility for continued maintenance of these areas.
C. 
Easements.
(1) 
Easements with a minimum width of 20 feet shall be provided as necessary for utilities.
(2) 
To the fullest extent possible, easements shall be centered or adjacent to rear or side lot lines.
(3) 
Where a subdivision is traversed by a watercourse, there shall be provided a drainage easement or right-of-way conforming substantially with the line of such watercourse (with the watercourse to be straightened where reasonably possible) and of such width as will be adequate to preserve natural drainage.
D. 
Blocks. The length, width and shape of blocks shall be determined with due regard to the following:
(1) 
Provisions of adequate sites for buildings of the type proposed.
(2) 
Zoning requirements.[1]
[1]
Editor's Note: See Ch. 166, Zoning.
(3) 
Topography.
(4) 
Requirements for safe and convenient vehicular and pedestrian circulation.
E. 
Storm drainage. Lots shall be laid out to encourage positive drainage away from proposed building areas; and wherever desirable, natural drainage courses shall be maintained.
F. 
Design standards for streets.
(1) 
Street right-of-way widths. Minimum right-of-way widths for all proposed streets shall be no less than 50 feet.
(2) 
Geometric standards. Geometric design standards for all proposed streets shall conform to those established by the Pennsylvania Department of Transportation.
G. 
Street system layout.
(1) 
Proposed streets shall be properly related to such street plans or parts thereof as have been officially incorporated by Latrobe into its existing street plan, and they shall further conform to such county and state road and highway plans as have been prepared and/or filed as prescribed by law.
(2) 
The proposed street layout shall provide for the continuation or projection of existing streets in the surrounding area unless the Planning Commission deems such extension undesirable for specific reasons of topography or design.
(3) 
Streets shall be logically related to the topography to produce usable lots and reasonable grades.
(4) 
Minor streets shall be laid out to discourage through traffic, but provision for street connections into and from adjacent areas will generally be required.
(5) 
Proposed streets shall be extended to provide access to adjoining property where necessary.
(6) 
Adequate street rights-of-way shall be provided as necessary where lots in the proposal are large enough to permit resubdivision or if a portion of the tract is not subdivided.
(7) 
New half or partial streets will not be permitted, except where essential to reasonable subdivision of a tract in conformance with the other requirements and standards contained herein and where, in addition, satisfactory assurance for dedication of the remaining part of the street can be secured.
(8) 
Wherever a tract to be subdivided borders an existing half or partial street, the other part of the street shall be plotted within such tract.
(9) 
Dead-end streets shall be prohibited, except as temporary culs-de-sac to permit future street extension into adjoining tracts.
(10) 
New reserve strips, including those controlling access to streets, shall be avoided.
(11) 
New streets which are extensions of existing streets shall bear the name of existing streets.
H. 
Street intersections. Street intersections shall conform to all applicable rules and regulations of the Pennsylvania Department of Transportation.
I. 
Uses fronting on major traffic streets or abutting highway interchanges. Proposed uses fronting on all streets shall be subject to the following regulations:
(1) 
Setback. Applicable setback requirements as set forth in the Latrobe Zoning chapter (Chapter 166 of this Code) shall be followed.
(2) 
Driveway access points.
(a) 
All residential structures shall be limited to no more than two driveway access points, except that properties which are less than 100 feet wide shall be limited to only one driveway access point.
(b) 
Such driveway access points shall be designed in a manner which will minimize their interference with any through traffic street or highway.
(c) 
Such driveway access points shall not exceed 24 feet in width at any such point.
(3) 
Service roads.
(a) 
The Council may require, upon the recommendation of the Planning Commission, the provision of service roads, marginal access roads, rear street alleys, reverse frontage lots or such other treatment which will provide protection for abutting properties or reduce the number of intersections and separate local and through traffic along any major traffic street or approach highway.
(b) 
Where a major traffic street or highway passes through a developed section of the community, Latrobe, upon the recommendation of the Planning Commission, may determine that the existing conditions in the area and the character of existing development render compliance with the above regulations impractical. In such cases, Latrobe, may make a minimum reduction to these requirements, only to the extent necessary required by existing conditions, and in keeping with the intent and objectives of this section.
A. 
Application. All subdivisions proposed for residential use shall conform with the provisions of this section.
B. 
Residential lot sizes. Lot dimensions, areas, yards and building setback lines shall be not less than specified by the provisions of the zoning regulations.[1]
[1]
Editor's Note: See Ch. 166, Zoning.
C. 
Design of residential lots.
(1) 
All lots shall front upon a public street, existing or proposed.
(2) 
Side lot lines shall be substantially at right angles or radial to street lines.
(3) 
If remnants of land exist after subdividing, they shall be incorporated in existing or proposed lots or dedicated to public use if acceptable to Latrobe.
(4) 
Depth and width of parcels laid out or reserved for nonresidential use shall be sufficient to provide satisfactory space for off-street parking and unloading.
D. 
Residential blocks. Residential blocks shall be of sufficient depth to accommodate two tiers of lots, except where reverse-frontage lots bordering a major traffic street are used.
E. 
Cul-de-sac streets.
(1) 
Cul-de-sac streets, permanently designed as such, shall not exceed 800 feet in length and shall access to not more than 20 dwelling units. This requirement may be waived where the Planning Commission determines the physical features of the site deem it necessary.
(2) 
Cul-de-sac streets shall be provided at the closed end with a paved turnaround having a minimum radius to the outer pavement edge or curbline of 40 feet.
(3) 
Unless future extension is clearly impractical or undesirable, a right-of-way of the same width as the street shall be carried to the property line in such a way as to permit future extension of the street into the adjoining tract.
A. 
Application. All commercial and industrial subdivisions shall conform with the provisions of this section.
B. 
Size. Approval of lot or parcel size will be determined by the following factors:
(1) 
The total area shall be sufficient to provide adequate space for off-street parking and loading, landscaping and other facilities.
C. 
Street system.
(1) 
Traffic movements in and out of commercial and industrial areas should not interfere with external traffic, nor should it create hazards for adjacent residential areas.
(2) 
The design of streets, service drives and pedestrianways should provide for safe and hazard-free internal circulation.
