a. 
Streets.
1. 
General.
(a) 
The arrangement of streets shall conform to the master plan.
(b) 
For streets not shown on the master plan or official map, the arrangement shall provide for the appropriate extension of existing streets.
(c) 
Streets shall be arranged so as to discourage through traffic and provide for maximum privacy.
2. 
Street Hierarchy.
(a) 
Streets shall be classified in a street hierarchy system with design tailored to function.
(b) 
The street hierarchy system shall be defined by road function and traffic. The following classification shall be utilized in the Borough and each proposed street shall be classified and designed for its entire length to meet the described standards.
(1) 
Collector streets collect traffic from local streets and channel it into the system of arterial highways. The right-of-way width for collector streets within the jurisdiction of the Borough is sixty (60') feet. The right-of-way shall have a cartway width of at least forty (40') feet to allow for two twelve (12') foot wide moving lanes and two eight (8') foot wide parking lanes. In addition, the right-of-way width shall allow for curb, sidewalk, utility, and shade tree installation.
(c) 
Local streets provide frontage for access to lots and carry traffic having destination or origin on the street itself. The minimum right-of-way width for local streets is fifty (50') feet. The right-of-way shall have a cartway width in accordance with Residential Site Improvement Standards (RSIS). In addition, the right-of-way width shall allow for curb, sidewalk, utility, and shade tree installation. Any street not designated as a collector street is a local street.
3. 
Cartway Width. The determination as to cartway width shall also consider possible limitations imposed by sight distances, climate, terrain, emergency services access and maintenance needs. The Municipal Agency may require increases or decreases in cartway width where appropriate.
4. 
Curbs and Gutters.
(a) 
Curbing shall be required for drainage purposes, safety, and delineation and protection of pavement edge.

(b) 
Shoulder requirements shall vary according to street hierarchy and intensity of development.
(c) 
Shoulders may consist of reduced pavement section or after construction approved by the Municipal Agency.
6. 
Sidewalks.
(a) 
Sidewalks shall be placed in the right-of-way, parallel to the street within the right-of-way, unless an exception has been permitted to preserve topographical or natural features, or to provide visual interest, or unless the applicant shows that an alternative pedestrian system provides safe and convenient circulation. In commercial and more intensely developed residential areas, sidewalks may abut the curb.
(b) 
Pedestrian way easements a minimum of ten (10') feet wide may be required by the Planning Board through the center of blocks more than six hundred (600') feet long to provide circulation or access to schools, play-grounds, shopping, or other community facilities.

Public sidewalks, shared use paths, and other pedestrian circulation paths must comply with the Access Board's Pedestrian Access Route requirements.
(g) 
Whenever a developer within the Borough of Rumson is required by ordinance, statute or stipulation of the Planning Board or Zoning Board of Adjustment to install sidewalks, the applicable Board may waive said sidewalk requirement at the request of the developer, or on its own initiative. Upon the granting of such a waiver, the developer shall be required to pay to the Borough of Rumson an amount equal to the reasonable cost of installing said sidewalks, said amount to be determined by the Borough Engineer upon submission and consideration of various estimates and other documentation from the developer, other interested parties and the office of the Borough Engineer itself, taking into account factors such as the application of prevailing wage requirements added to the Borough's construction costs. All funds collected by the Borough of Rumson from developers as set forth above shall be maintained in a Sidewalk Capital Construction Fund account which is hereby authorized and created, the proceeds of which shall be made available to install sidewalks throughout the Borough of Rumson where properly authorized by the Mayor and Council. Nothing contained herein shall affect the right of the Borough of Rumson to enact ordinances requiring assessments for sidewalks from property owners as authorized under N.J.S.A. 40:65-2, or other statutory rights granted to municipalities.

13. 
Underground Wiring.
(a) 
All electric, telephone, television, and other communication facilities, both main and service lines servicing new developments, shall be provided by underground wiring within easements or dedicated public right-of-way, installed in accordance with the prevailing standards and practices of the utility or other companies providing such services.
(b) 
Lots which abut existing easements or public rights-of-way where overhead electric or telephone distribution supply lines and service connections have hereto before been installed may be supplied with electric and telephone service from those overhead lines, but the service connections from the utilities' overhead lines shall be installed underground. In the case of existing overhead utilities, should a road widening, or an extension of service, or other such condition occur as a result of the subdivision and necessitate the replacement or relocation of such utilities, such replacement or relocation shall be underground.
(c) 
Where overhead lines are permitted as the exception, the placement and alignment of poles shall be designed to lessen the visual impact of overhead lines as follows: Alignments and pole locations shall be carefully routed to avoid locations along horizons; clearing swaths through treed areas shall be avoided by selective cutting and a staggered alignment; trees shall be planted in open areas and at key locations to minimize the view of the poles and the alignments; and alignments shall follow rear lot lines and other alignments.

For nonresidential developments, the parking standards shown in Exhibit 9-2 of this section shall be used as a guideline.
(d) 
Alternative off-street parking standards shall be accepted only if the applicant demonstrates that these standards better reflect local conditions.
(e) 
The Municipal Agency may require the use of alternative standards if it determines that the ordinance standards are insufficient or a particular development has unique parking requirement. The basis for such a determination shall be documented by the Municipal Agency in its minutes.
(f) 
All required residential parking shall be located behind the front yard setback line. A garage shall only be counted as off-street parking where the access driveway is at least thirty (30') feet long or where the Municipal Agency agrees to accept such garage space as meeting requirements.
(g) 
Where the total number of off-street parking spaces required may not be immediately required for a particular use, a staged development plan may be permitted which requires that only a portion of the parking area, but not less than 65% of the required spaces be completed initially, subject to the following regulations:
(1) 
The site plan shall clearly indicate both that portion of the parking area to be initially paved and the total parking needed to provide the number of spaces required.
(2) 
The site plan shall provide for adequate drainage of both the partial and total parking areas.
(3) 
The portion of the parking area not to be paved initially shall be landscaped in accordance with Section 22-8.
(4) 
The applicant shall post separate performance guarantees, in addition to the performance guarantees required under Section 22-10 which shall reflect the cost of installing the additional parking facilities necessary to provide the total number of parking spaces required.
(5) 
In lieu of a permanent certificate of occupancy, a temporary certificate of occupancy shall be issued for a period of two years. Prior to the expiration of the two year period, the applicant may either install the additional parking spaces shown on the site plan and apply for issuance of a permanent certificate of occupancy or apply to the Planning Board after the use has been in operation a minimum of 18 months for a determination as to whether or not the initial parking area provided is adequate. If the Planning Board determines that the parking facility is adequate as originally constructed, the performance guarantees shall be released and a permanent certificate of occupancy issued. If, however, the Planning Board determines that the partial off-street parking area is not adequate, the applicant shall be required to install the additional parking facilities in accordance with the terms of the performance guarantees prior to issuance of a permanent certificate of occupancy.
(6) 
Any change of use on a site for which the Planning Board may have approved a partial paving of off-street parking areas to a use which requires more parking spaces than are provided on the site shall require submission of a new site plan.

Stormwater Management.
1. 
Purpose.
(a) 
It is hereby determined that the waterways within the Borough of Rumson are at times subjected to flooding; that such flooding is a danger to the lives and property of the public; that such flooding is also a danger to the natural resources of the Borough of Rumson, the County and the State; that development tends to accentuate flooding by increasing storm water runoff, due to alteration of the hydrologic response of the watershed in changing from the undeveloped to the developed condition; that such increased flooding produced by the development of real property contributes increased quantities of water-borne pollutants, and tends to increase channel erosion; that such increased flooding, increased erosion, and increased pollution constitutes deterioration of the water resources of the Borough of Rumson, the County and the State; and that such increased flooding, increased erosion and increased pollution can be controlled to some extent by the regulation of storm water runoff from such development. It is therefore determined that it is in the public interest to regulate the development of real property and to establish standards to regulate the additional discharge of storm water runoff from such developments as provided in this chapter as well as Chapter 16, Environmental Protection, Section 16-2, Stormwater Management and Control.
(b)
