NOTES:

1 Shoulders or parking areas as required may be of reduced structural design.

2 To be individually designed based on traffic projections and AASHTO design standards. Design to meet at least major collector standards.

3 For sight distance and vertical curve calculations only.

4 Or as required to run out superelevation (1% per second of travel at design speed).

5 Not required if algebraic difference of intersecting grades does not exceed 1%.

6 Except in superelevation areas.

E. No minor or major development showing reserve strips controlling access to streets or another area, either developed or undeveloped, shall be approved except where the control and disposal of land comprising such strips has been placed with the governing body under conditions approved by the approving authority.

F. In the event that a minor or major development adjoins or includes existing Township streets that do not conform to widths as shown on the Master Plan or Official Map or the street width requirements of this chapter, additional land along either or both sides of said street or road sufficient to conform to the right-of-way requirements shall be dedicated to the Township for the location, installation, repair and maintenance of streets, drainage facilities, sewage facilities, utilities and other facilities customarily located on street rights-of-way and shall be expressed on the plat as follows: "Street right-of-way easement granted to the Township of Marlboro permitting the Township to enter upon these lands for the purposes provided for and expressed in the Development Regulations Ordinance of the Township of Marlboro." This statement on an approved plat shall in no way reduce the developer's responsibility to provide, install, repair or maintain the facilities in the area dedicated by ordinance and/or shown on the plat and/or as provided for by maintenance or performance guaranty. If the development is along one side only, 1/2 of the required extra width shall be dedicated. For a major development, that portion of the existing street or road adjoining or included within a development shall be improved, including excavation, grading, gravel base and surfacing, in accordance with the road improvement standards of this chapter.

G. Longitudinal grades of arterial and collector streets shall not exceed 4%. Longitudinal grades on other streets shall not exceed 10%. No street shall have a longitudinal grade of less than 1/2 of 1%.

H. Street intersections shall be as nearly at right angles as is possible, and in no case shall be less than 60. No more than two streets shall meet or intersect at any one point, and the center lines of both intersecting streets shall pass through a common point. Measuring from this common point, two intersections shall be spaced a sufficient distance to permit a minimum of two lots between the two street rights-of-way. Any development abutting an existing street classified as a primary or secondary arterial or major collector shall be permitted only one new street connecting with the existing street except where large frontages are present, in which case streets shall not intersect with the same side of the existing street at intervals of less than 800 feet. The block corners at intersections shall be rounded at the curbline with a curve having a radius of not less than the following, with the street having the highest radius requirement determining the minimum standard of all curblines: primary and secondary arterials, 40 feet; major and minor collectors, 35 feet; and local streets, 30 feet.

I. For both major and minor developments, sight triangle easements shall be required at all intersections in addition to the right-of-way width outlined above and in accordance with requirements and dimensions covered in § 220-179, Sight triangles. Such easement dedication shall be expressed on the plat as follows: "Sight triangle easement to which the indicated area is hereby subject are the conditions as provided in the Development Regulations Ordinance of the Township of Marlboro."

J. Street jogs with center-line offsets of less than 150 feet shall be prohibited.

K. A tangent at least 100 feet long shall be introduced between reverse curves on arterial and collector streets. When connecting street lines deflect from each other at any one point by more than 10, they shall be connected by a curve with a radius conforming to standard engineering practice.

L. All changes in grade where the algebraic difference in grade is 1% or greater shall be connected by vertical curves of sufficient radius to provide a smooth transition and proper sight distance. Sight distance shall be at least three 350 feet for a local street, 500 feet for a collector street and 800 feet for an arterial street.

M. Dead-end streets.

(1) Dead-end streets (culs-de-sac) of a permanent nature, where provision for the future extension of the street to the boundary of the adjoining property is impossible or impractical, or of a temporary nature, where provision is made for the future extension of the street to the boundary line of adjoining property, shall provide a turnaround at the end with a radius of 55 feet on the curbline plus a utility and planting strip width of seven feet around the entire cul-de-sac. The center point for the radius shall be offset to the left, as entering, such that the radius becomes tangent to the right curbline. [Amended 9-10-1987 by Ord. No. 32-87]

(2) If a dead-end street is of a temporary nature, provisions shall be made for removal of the turnaround and reversion of the excess right-of-way to the adjoining properties when the street is extended.

N. No street shall have a name which will duplicate or so nearly duplicate in spelling or phonetic sound as to be confused with the names of existing streets. The continuation of an existing street shall have the same name.

O. Construction.

(1) Streets shall be constructed in accordance with the following schedule and specifications:

For Primary and Secondary Arterial and Major Collector Streets

+ Defines cross-sectional slope of pavement surface toward curb or pavement edge.

For Minor Collector, Local and Rural Streets

(2) The various pavement course shall be constructed in accordance with the following specifications:

(a) Bituminous stabilized base course shall be plantmixed and shall be constructed in layers of not more than 2 1/2 inches compacted thickness and shall be prepared and constructed in accordance with Division 3, Section 2A, of the New Jersey State Highway Department Standard Specifications for Road and Bridge Construction (1961), and amendments and supplements thereto; subbase material shall consist of either natural soil which may be found at the sources and placed up to the subgrade elevation, which, in any event, shall possess good vertical drainage characteristics, shall be free of large masses of clay and shall be capable of being suitably compacted and stabilized prior to placement of the base course, or soil aggregate Type V, Class A, as specified in Division 8, Section 8, of the aforesaid specifications, which shall be placed, compacted and graded to the required thickness and shall be constructed in accordance with Division 3, Section 10, of the aforesaid specifications.

(b) Where the Township Engineer determines that the subbase conditions of proposed streets are wet, springy or of such nature that surfacing would be inadvisable without first stabilizing the subbase, the stabilization of the subbase shall be made in the following manner. The street shall be excavated to a depth that shall be a minimum of 13 inches below the proposed finished grade. Where required by the Township Engineer, a system of porous concrete pipe subsurface drains shall be constructed beneath the surface of the road and connected to a suitable drain. Subbase material consisting of soil aggregate Type 1, Class A, B or C, or Type V, Class A, as specified in Division 8, Section 8, of the New Jersey State Highway Department Standard Specifications for Road and Bridge Construction (1961), and amendments and supplements thereto, or bank-run sand and gravel containing not more than 1/2 of 1% of elutriable clay, shall be placed a minimum of six inches thick under the proposed pavement. After the subbase material has been properly placed and compacted, the street pavement as described heretofore shall be constructed thereon.

P. In all developments subject to Subsection C above or the cluster development provisions, the approving authority may require paved bike paths within the seventy-five-foot-wide dedicated land strip along existing streets, in accordance with the considerations and requirements covered in § 220-142, Bikeways.

G. Letters shall be four-inch high-intensity letters.

Private, permanent residential swimming pools shall adhere to the following standards in addition to the swimming pool regulations:

A. No pool or wading pool shall be constructed or installed on any lot unless said lot shall contain a residential building. All pools shall meet the yard requirements for accessory buildings in the district in which such pool is located, except that if located in the front yard, the pool shall be set back twice the distance from the street line than is required for principal building.

B. A pool and associated accessories shall occupy no more than the equivalent of 75% of the yard area in which they are located.

Nothing in this chapter shall prevent local, temporary civic activities such as fairs and carnivals from being conducted in any zone, provided they are limited in duration to a maximum of two weeks.

No trailer, auto trailer, mobile home, trailer coach, travel trailer or camper shall be used for dwelling purposes or as sleeping quarters for one or more persons or for the permanent conduct of any business, profession, occupation or trade, except that such facilities may be used for temporary residency as the temporary replacement of a damaged dwelling unit and for temporary use as a construction office located on a site during active construction, provided a temporary permit for a specified interval has been issued for its use by the Building Inspector. This section shall not be construed so as to prohibit the parking or storage of trailers and campers on private premises.

Any parcel of land which does not meet the minimum lot size requirements prescribed for a lot in the zone in which such lot is located and which is not under common ownership with adjacent lands and which parcel existed as a lot on the date of this chapter may be used as a lot for any purpose permitted in the zone, provided that the width of each side yard and the width of the rear yard must equal or exceed 20% or 12 1/2%, respectively, of the width of the lot for main buildings or structures and 12 1/2% of the width of the lot for side and rear setback lines for accessory buildings, and in no case shall any main or accessory building or structure or part thereof be less than 15 feet from any property line, and provided further that all other regulations prescribed for the zone by this chapter are complied with. See § 220-141, Area requirements.
