All subdivision plans must reflect a location which has given consideration to the following factors:
A. 
The location of the subdivision must conform to the Jefferson Borough Comprehensive Plan with respect to streets, public sites and proposed utilities.
B. 
The proposed use of the land in any subdivision must conform to the Zoning Ordinance of Jefferson Borough.[1]
[1]
Editor's Note: See Ch. 198, Zoning.
C. 
Land subject to hazards of life, health or property as may arise from fire, floods, disease, excessive noise, falling aircraft or considered uninhabitable for other reasons may not be subdivided unless the hazards have been removed or the plans show adequate safeguards against them.
D. 
A subdivision must be coordinated with existing development in the neighborhood so the entire area may be developed harmoniously.
In the layout of any subdivision, attention must be focused on conditions which can affect development. These can include the following.
A. 
In all subdivisions, all natural and historic features shall be maintained on the basis of Borough determination. In subdivisions where woods or scattered trees exist of such nature and quality that the Borough considers them deserving of preservation a grading plan may be required. The grading plan shall show the following:
(1) 
Accurate location of significant individual trees.
(2) 
Accurate existing and proposed ground elevation in relation to these trees. Necessary in order to ensure their continued healthy growth may be the following requirements: permanent tree guards, temporary tree guards during construction and grading and limitation as to cuts and fills near the trees.
B. 
In subdivisions subject to periodic or permanent high water table, a drainage plan prepared by an engineer is required. The drainage plan shall show the following:
(1) 
Present and future elevations.
(2) 
All present and proposed facilities for elimination of the high water table.
C. 
Except for a privately created water body, where the subdivision is adjacent to a lake or other such large water body, the following general standards shall apply:
(1) 
No building may be located within 60 horizontal feet of the median ordinary high water level (maximum pool) or so located that the lowest floor is less than three feet above the ordinary high water level.
(2) 
No structure may be erected beyond the established wharf or dock line.
(3) 
Public accesspoints shall be provided to the water body at an interval of not less than one point in every 1/2 mile along the shore.
(4) 
No building may be erected in any designated floodplain area.
All streets proposed to be constructed within the Borough shall conform to the following general design requirements:
A. 
Proposed streets shall be planned with regard to the existing street system, topographical conditions, public convenience in terms of fire protection and pedestrian traffic, probable volumes of traffic, existing and proposed use of land on abutting properties and future subdivision extensions of the street system.
B. 
The proposed street system shall be, whenever possible, coordinated with the existing system. The proposals shall provide for continuation of the existing system.
C. 
Proposed streets which are aligned with existing streets shall bear the name of the existing street. In the event a proposed street is not aligned with an existing street, it shall not bear a name similar to any existing street located within the Borough and/or the same postal service area, irrespective of the suffix "street," "avenue," "boulevard," "drive," "place," "court," etc.
D. 
Where the lots in a subdivision are large enough for resubdivision, or where a portion of the tract is not subdivided, suitable access to these areas shall be provided.
A. 
Blocks: length and depth. The general shape, length and depth of blocks shall be determined on the following bases:
(1) 
Provision of adequate building sites suitable to the special needs of the type of use contemplated.
(2) 
The Zoning Ordinance of Jefferson Borough that may be adopted by the Borough Council.[1]
[1]
Editor's Note: See Ch. 198, Zoning.
(3) 
Needs for convenient access, circulation, control, safety of street traffic.
(4) 
Limitations and opportunities of topography.
(5) 
Normally block length shall not exceed 1,600 feet nor be less than 500 feet.
(6) 
Except where reverse frontage lots border an arterial, double frontage lots shall be prohibited.
B. 
Blocks in commercial and industrial areas. In commercial and industrial areas, the block layout shall be designed with reference to service of the public and with provisions for adequate off-street parking and loading facilities, as well as future expansion. If the nature of the use requires special treatment, block length and width requirements in commercial and industrial districts may vary from the elements of design contained in this section.
C. 
Lot layout in subdivision:
(1) 
Insofar as is possible, all lots shall be:
(a) 
Perpendicular to the right-of-way lines.
(b) 
Those fronting on curves shall be radial to the right-of-way lines.
(c) 
Every lot shall abut by their full frontage on a dedicated public street.
(2) 
The shape of lots must be appropriate for the location of the subdivision and for the type of development and use contemplated. Lot sizes, widths, depths and setbacks shall apply as specified in the Jefferson Borough Zoning Ordinance or as detailed in Appendix 1 of this chapter until such time that a Zoning Ordinance is adopted by the Borough.[2]

D. 
Planting screens. Where lots face an interior street and back on a major thoroughfare or abut properties in other uses with an adverse effect upon them, a planting strip at least 15 feet wide for a screen shall be provided along the back or abutting side of the lot, as the case may be. No right of access may open onto or through the strip. Where lots back on a creek or other natural barrier, there may also be required a fifteen-foot planting strip.
E. 
Grading. Blocks and lots shall be graded to sufficient elevation to secure drainage away from buildings and to prevent the collection of stormwater in pools. Roof drainage shall be provided for according to recommendations of the Engineer or such other officials as may be designated by the Borough Council. Topsoil shall be preserved and redistributed as cover and shall be suitably planted with perennial grasses or ground cover.
F. 
Residential parking. At least two off-street parking spaces with access to a public street shall be provided for each proposed dwelling unit. Where such access is to other than a residential service street, adequate turnaround space shall be provided on the lot.
G. 
House numbers. House numbers shall be assigned to each lot by the Borough.
The design, layout and required improvements for mobile home parks are specified in Appendix 2 of this chapter.[1] Except as provided otherwise in Appendix 2, a mobile home park must comply with all provisions of this chapter. The Jefferson Borough Planning Commission may vary the terms as they apply to mobile home parks when, in the opinion the Jefferson Borough Planning Commission, equal performances can be obtained by means other than those specified herein.
