§ 395-21. General street design standards.

A. 

All design elements of all streets, including existing function, horizontal and vertical alignment, sight distance, and superelevation, are subject to review and approval by the Borough Council. When reviewing the design of streets, in addition to the standards in this chapter, the Rural Design Criteria in the Pennsylvania Department of Transportation Design Manual, Part 2, Highway Design, January 1990 edition, and A Policy on Geometric Design of Highways and Streets, AASHTO, current edition, as from time to time amended and supplemented, shall be in accordance with acceptable engineering practice.

B. 

For certain aspects of vertical and horizontal alignment discussed below, standards are determined by design speed of the street involved. For all proposed streets, the applicant shall indicate the proposed design speed. The designated design speed is subject to the approval of the Borough Council, in accordance with acceptable PennDOT standards.

C. 

The speed limit proposed to be posted for streets shall not exceed the design speed.

D. 

Streets in and bordering a subdivision or land development shall be coordinated, and be of such widths and grades and in such locations as deemed necessary to accommodate prospective traffic and facilitate fire protection.

E. 

The location and width of all proposed streets shall conform to the official plans which have been adopted by the Borough and shall be properly related to all existing streets, recorded streets, and official plans which have been adopted or approved by the Borough, county, or state.

F. 

Streets within the subdivision or land development and adjacent roads which will receive traffic from and distribute traffic to the subdivision or land development shall be adequate in construction, grade, width and capacity to accommodate traffic generated by the subdivision or land development.

G. 

The proposed street system shall extend existing or recorded streets at the same width as the existing or recorded streets if these streets meet or exceed the standards of § 395-23A. If the existing or recorded streets do not meet or exceed the standards of § 395-23A, the proposed street extensions shall meet the standards of § 395-23A.

H. 

Where, in the opinion of the Borough Council, it is desirable to provide for street access to adjoining property, streets shall be extended by dedication to the boundary of such property. The location and number of access points to adjoining properties are subject to Borough Council approval.

I. 

When streets will be extended to the boundaries of the subdivision or land development to provide for access to potentially developable tracts and sanitary sewer and/or water lines will be constructed in the streets within the applicant's tract, the Borough Council may require extension of the sanitary sewer and/or water lines to the tract boundary in order to facilitate future extensions to abutting land.

J. 

If a subdivision proposes lots, all of which front on existing public streets, the Borough Council may require the applicant to reserve land adequate to provide for future street access from the public streets on which the lots front to the land to the rear of the proposed lots. Such reserved areas shall be of such dimensions to permit the construction of streets meeting the standards of this chapter.

(1) 

When reservations for future streets will adjoin lots to be developed prior to the construction of the streets, the applicant shall establish the proposed grades of the future streets and the extent of the area necessary for the construction of those streets. If the area necessary for the construction of the streets extends beyond the proposed street right-of-way lines, all excavation and grading necessary for the streets beyond the right-of-way lines shall be done as required improvements in conjunction with the subdivision which contains the adjoining lots or else construction easements shall be provided on the adjoining lots, sufficient to permit construction of the future street.

(2) 

Where reservations for future streets intersect existing streets, radii shall be provided for the reservations such that the requirements of § 395-28F and G of this chaptercould be met for a street to be constructed in the future.

K. 

If lots or parcels in the subdivision are large enough for resubdivision, or if a portion of the applicant's property is not proposed to be subdivided but could be subdivided in the future, the Borough Council may require the reservation of land adequate to provide for future street access to land which could be resubdivided or subdivided in the future and require that the location of land reserved for future streets be coordinated with the street system shown on the subdivision plan.

L. 

Connections shall be provided between streets within the subdivision or land development to provide adequate access for emergency vehicles, other vehicles, and pedestrians.

M. 

New minor streets shall be so designed as to discourage through traffic, but the applicant shall provide for the extension and continuation of arterial and collector streets into and from adjoining properties when required by the Borough Council. Minor streets shall be extended and continued into and from adjoining properties when necessary for the proper development of and traffic circulation in the Borough.

N. 

Where a subdivision or land development abuts an existing street which does not meet the standards of this chapter, the Borough Council may require the dedication of land sufficient to widen the street to meet the standards of this chapter.

O. 

Where a subdivision of land development fronts on and will provide for vehicular access to and from an existing Borough street which does not meet the minimum cartway width requirements of this chapter, the Borough Council may require the applicant to improve at his expense the Borough street cartway to meet those requirements. Pavement shall be constructed in accordance with the requirements of this chapter. In addition, provision shall be made for adequate drainage along the sides of the streets. Such drainage provisions shall be approved by the Borough Council.

P. 

Private streets (streets not to be offered for dedication) shall be designed and constructed in accordance with the requirements of this chapter and other Borough regulations, including Ordinance No. 4-1974, as from time to time amended and supplemented, except as follows:

(1) 

Private streets need not conform in width to the requirements of § 395-23A of this chapter; provided, however, that private streets shall have a cartway of not less than 24 feet unless a greater width is required by Chapter 450, Zoning, of the Code of the Borough of Walnutport; and provided further, that no parking shall be permitted on any private street that does not contain the width requirements of § 395-23A of this chapter.

(2) 

Private streets shall only be permitted in those subdivisions or land developments intended to remain under single ownership.

Q. 

Where streets and other public improvements continue into adjoining municipalities, evidence of compatibility of design, particularly with regard to street widths, shall be submitted. The applicant shall coordinate such design with both municipalities to avoid abrupt changes in cartway width or in improvements provided.

R. 

The street system shall be signed with regard to:

(1) 

Consideration of existing topographical considerations.

(2) 

Providing buildable lots, or in the case of a mobile home park, lots on which a mobile home can be placed in accordance with all applicable requirements of Chapter 450, Zoning, of the Code of the Borough of Walnutport.

(3) 

Minimizing the number of street intersections through encouraging the use of three-way rather than four-way intersections when intersections of minor streets are involved.

(4) 

Avoiding excessive lineal footage of street.

S. 

All drives within multiple-family and nonresidential developments which are intended for circulation within the development shall be designed to the horizontal and vertical alignment standards for streets contained within this chapter.
