Editor's Note: This ordinance, originally codified as Ch. 107, Stormwater Management, was renumbered and retitled 11-28-2006 by Ord. No. 3125-06, which also adopted a new Ch. 107A, Stormwater Management Control, State.
A. 
The general intent of this chapter is to manage the increased rate and velocity of surface water runoff created by certain alterations of the ground cover and natural runoff patterns.
B. 
This chapter is deemed essential and necessary to protect the public health, safety and welfare of the citizens of the Borough of Rutherford and the surrounding communities by accomplishing the following purposes:
(1) 
To reduce flood damage to public health, life and property.
(2) 
To minimize increased stormwater runoff from any new land development.
(3) 
To maintain the adequacy of existing and proposed culverts and bridges.
(4) 
To induce water recharge into the ground where practical.
(5) 
To prevent, to the greatest extent feasible, an increase in non-point-source pollution.
(6) 
To maintain the integrity of stream channels for their biological functions as well as for drainage and other purposes.
(7) 
To reduce the impact of development upon stream erosion in areas where this would be detrimental.
(8) 
To reduce erosion from any development or construction project.
(9) 
To minimize the increases in runoff pollution due to land development which otherwise would degrade the quality of water and might render it both unfit for human consumption and detrimental to biological life.
(10) 
To preserve and protect water supply facilities and water resources by means of controlling harmful flood discharges, stream erosion and runoff pollution.
(11) 
To reduce public expenditures for replacement or repair of public facilities resulting from artificially induced flood peaks.

(8) 
Any other factors relevant to the coordinated, adjusted and harmonious development of the site, vicinity, township and region.
B. 
If, after considering the above factors and after consultation with the Engineer, the Planning Board determines that the proposed land disturbance or construction will generate no surface water runoff that will not be managed in accordance with standards of this chapter or will not be detrimental to the public health, safety and general welfare in light of the paramount interest in the prevention of conditions which may result in surface runoff damage, the Planning Board shall approve the plan and issue the necessary permit. If the Planning Board shall determine, after consultation as provided above, that the proposed land disturbance or construction will be detrimental to the public interest as defined above, the Planning Board shall deny the permit and shall clearly and concisely state the reasons.

E. 
Retention/detention basins.
(1) 
Retention or detention basins constitute an acceptable means of achieving the goals stated in § 107B-1. Innovative techniques for limiting peak runoff are encouraged. All methods are subject to review by the Borough Engineer and to approval by the Board.
(2) 
Where basins are used, they shall be so located on the site as to pose the least potential hazard and nuisance to downstream and surrounding properties. As a minimum, all portions of the basin, including earthen embankments, shall comply with the setback requirements applicable to the zone in which they are situated. Notwithstanding conformance to the setback limitations, the location must be satisfactory to the Board.
(3) 
Standards of design for detention of floodwater-retarding structures shall conform to the following criteria or to those promulgated pursuant to the Soil Erosion and Sediment Control Act of 1975.[1] Should said standards be contradictory, the more stringent shall apply. The design inflow shall be determined for the drainage areas as stated above (see § 107B-6N). A storm of one-hundred-year frequency and twenty-four-hour duration shall govern the size of the basin. The basin shall have the demonstrated capability to attenuate storms of the one-, twenty-five- and one-hundred-year frequencies to the extent required. Emergency spillways shall be adequate for a one-hundred-year storm flow plus 33%.

The applicant shall provide the services of a testing laboratory as directed by the Borough Engineer to confirm that proper compaction has been achieved. The entire basin construction shall be subjected to inspection by the Borough Engineer. Embankments shall be constructed to a height above the design top elevation to accommodate settling plus two-foot freeboard. The use of embankments as driveways is discouraged. Dams and embankments must be maintained free from trees, burrows and erosion during the life of the facility.
(5) 
Principal spillways and affiliated components must have a design life at least equal to that of the entire basin. Outlets shall promote stable downstream channel conditions. Trash racks to prevent spillway fouling shall be considered. All basins shall also have an emergency spillway in addition to the principal outflow structure. Basins designed to retain waters during dry weather periods shall not be acceptable.
