Easements of a width sufficient to allow proper maintenance shall be provided for the installation of all drains, storm drains, pipelines, gas mains, etc. Said easements shall be dedicated to the municipality by approved legal procedure. Easements along rear property lines or elsewhere for utility installation may be required; such easements shall be at least 20 feet wide for a single utility plus an additional five feet for each additional utility. They shall be located in consultation with the companies or municipal departments concerned.

Where a subdivision is traversed by a watercourse, drainageway, channel or street, there shall be provided a stormwater easement or drainage right-of-way conforming substantially with the stream encroachment lines of such watercourse and such further width or construction, or both, as will be adequate for the purpose.

Natural features such as trees, brooks, hilltops and views shall be preserved whenever possible in designing any subdivision containing such features.

§ 350-19 Drainage.

Grading and drainage system plan.

A preliminary grading and drainage system plan shall be a part of the preliminary plat. It shall indicate in general terms a proposal for an adequate system of drainage structures to carry off and store or discharge the stormwater runoff and natural drainage water which originates not only within the property boundaries, but also that which originates beyond the property boundaries. It should perpetuate existing drainage patterns.

The public improvement and utilities plan and profiles shall show the final drainage plan, site grading and street profiles.

No stormwater runoff or natural drainage water shall be so diverted as to overload existing drainage systems or create flooding or the need for additional drainage structures on other private properties or public lands without proper and approved provisions being made for taking care of these conditions. Watersheds with drainage areas over 1/2 square mile come under the jurisdiction of the New Jersey Department of Environmental Protection. Approval of this agency must be secured for any culvert or bridge crossing falling into this category. Copies of any correspondence with the Department of Environmental Protection shall be supplied to the Borough Engineer.

Collection system.

The quantities of water for which the collection system shall be designed shall be in accordance with the Rational Method of design using the following formula:

Q = CIA
	Where:
		"Q" is the required capacity, in cubic feet per second, for the collection system at the point of design.
		"A" is the tributary drainage area, in acres, and shall include areas tributary from outside sources as well as from within the site itself.
		"C" is the coefficient of runoff applicable to the drainage area and shall be based on consideration of soil conditions, average slope of the drainage area and degree of ultimate development of the area, but in no case shall be less than the following coefficients:

			Topography
Usage		Density (units per acre)	Flat (0%-10%)	Rolling (10%-20%)	Hilly (Over 20%)
Residential
	High-density	4-6	0.50 (0.40)	0.55 (0.45)	0.60 (0.55)
	Medium-density	1-4	0.45 (0.35)	0.50 (0.40)	0.55 (0.50)
	Low-density	Fewer than 1	0.40 (0.30)	0.45 (0.35)	0.50 (0.45)
Impervious surfaces			0.90	0.90	0.90
Undeveloped woodland			0.30 (0.20)	0.35 (0.25)	0.50 (0.45)
Pasture and grassed areas			0.30 (0.20)	0.36 (0.20)	0.42 (0.37)
Cultivated fields			0.50 (0.50)	0.60 (0.50)	0.72 (0.62)

The above runoff coefficients assume that clay soils (sand gravel soils coefficients indicated in parenthesis) are present. For residential uses, the coefficients assume that paved areas (parking) have been provided. Any deviation from these factors would result in an adjustment in "C" values. Determination of nonlisted uses shall be a subject of special study and approved by the Borough Engineer.

"I" is the rainfall intensity, in inches per hour, and shall be determined from the graph entitled "Rainfall Intensity Duration for Essex and Union Counties," copies of which are on file with the Borough Clerk and which is made a part hereof. The minimum time of concentration shall be 10 minutes, which shall be used as the initial T, for all roadway drainage systems.

The following intensities shall be used to determine "Q."

Systems carrying roadway drainage: 10 years.

Cross pipes or culverts carrying runoff from one side of the roadway to the other (except cross pipes conveying runoff from a single inlet): 25 years; tributary areas over 20 acres: 50 years.

At low points and cuts from which water cannot escape without overflowing the roadway: 25 years.

Pipes or conduits shall be designed using Manning's equation for velocity:


	"R" is the hydraulic radius of the conduit flowing full.
	"n" is Manning's roughness coefficient, which shall be as follows:

Concrete pipe		0.012
Corrugated metal, 2 2/3 x 1/2 inches corrugations
	Plain or fully coated Paved invert Fully paved	0.024 0.020 0.012
3 x 1 inches corrugation		0.027
6 x 2 inches corrugation (field bolted)		0.032
"n" for other materials shall be as recommended by the Borough Engineer.
"S" is the slope of the energy gradient, in feet per foot, and shall generally be considered as being the same as the slope of the invert of the pipe (S₀); however, such slopes shall be checked against the available hydraulic gradient whenever the system flows full or where the system discharges into a body of water.

(4)

Velocity.

Wherever possible to ensure a self-cleansing velocity, pipes shall be placed on grades that will provide a minimum velocity of three feet per second when flowing 1/4 full. The following table indicates minimum grades to accomplish this:

	Desirable Minimum Gradients for Concrete Pipe
	Diameter (inches)	Slope N=0.012
	15 (minimum permissible)	.008
	18	.006
	24	.005
	30	.004
	36	.003
	42	.002
	48	.0016
	54	.0014
	60	.0012
	66	.0011

Where steep grades are encountered, full-flow velocities over 15 feet per second should be avoided by the use of drop manholes or inlets in the line.

(5)

Alignment.

Manholes or inlets shall be provided in drain lines not more than 350 feet apart and wherever branches are connected or sizes are changed and wherever there is a change in alignment or grade.

Alignment of pipes shall be in a straight line between manholes or inlets, except that radius pipe may be used in pipes over 60 inches in diameter, provided that a manhole or inlet is incorporated at not more than five-hundred-foot intervals.

(6)

Inlet spacing and headwalls.

Inlet spacing shall be such as to permit a spread of water to the edge of the traveled way (edge of shoulder for rural roads or edge or parking lane (eight feet maximum) for urban roads) during a storm with an intensity of three inches per hour. Inlet spacing may vary up to 350 feet, depending on the contributory drainage area and the longitudinal and cross slopes of the roadway. Inlets at intersections shall be located to intercept water before it crosses the intersection or crosswalk area, and inlets shall not be placed in the crosswalk area. Pairs of inlets shall be placed at low points.

Inlets intercepting swales or in parking areas shall be designed such that not more than six inches (three inches in parking areas) shall pond over an inlet during a storm with an intensity of three inches per hour.

Pipelines starting or ending in ditches, streams or other bodies of water shall terminate with either a headwall or a flared end section. Riprap or other suitable material shall be provided to prevent erosion.

(7)

Open channel flow. Where brooks, ditches, swales or other channel flows are used, they shall be designed by the use of Manning's equation, as indicated for collection systems above, with the following considerations:

The friction factor (n) shall be:

	Unlined
	Earth, uniform section		0.018 - 0.027
	Earth, nonuniform section		0.025 - 0.040
	Earth, not maintained		0.080 - 0.012

Lined
Concrete
	Finished	0.015
	Rough	0.25
Riprap		0.35

Design velocities should be limited to a nonerosive velocity and shall be determined based on an analysis of the soil conditions, but in any case shall not exceed the following:

	Materials	Velocity (feet per second)
	Fine sand to fine loam	2.5 to 3.5
	Stiff clay to hardpan	3.75 to 6.00
	Concrete-lined ditch	15

Velocities shall be controlled by use of check dams or baffles where necessary.

A ditch or brook right-of-way of sufficient minimum width to include a ten-foot access strip in addition to the width of the ditch or brook from bank top to bank top shall be offered for dedication to the Borough for drainage purposes. Such right-of-way shall be shown on the drainage plan and on the final plat.

Swales shall be provided in residential areas so that an area not in excess of the minimum lot area in the subdivision shall drain without being intercepted. This requirement may be varied for wooded sites or pervious soils.

Swales shall be provided in other areas so that not more than one impervious acre shall drain without being intercepted.

Jute mesh slope protection or Curlex^TM shall be used in swales or grassed ditches. Paved ditches shall be used where the velocity exceeds the erosive velocity.

Side slopes for a drainage way shall be as follows:

	Facility	Maximum Side Slope
	Channel	2:1
	Ditch	4:1
	Swale	6:1

(8)

Minimum cover and structural considerations.

All pipe shall be concrete, unless specific unique design considerations exist for the use of other types of materials, and then only with the approval of the Borough Engineer.

Minimum cover for reinforced concrete pipe shall be based upon a depth of cover of two feet from the top of the pavement to the top of the pipe.

Minimum cover for corrugated metal pipe shall be based upon a depth of cover of one foot from the top of the pipe to the top of the pavement or upon the manufacturer's recommendations, whichever is greater.

Maximum cover for pipe shall be based on rational analysis through use of Marston's formula. For reference, see the booklet Reinforced Concrete Pipe Culverts, issued by the United States Department of Commerce, and manufacturer's recommendations for flexible pipe.

Standard strength reinforced concrete pipe shall conform to Class 3, Wall B, and extra strength reinforced concrete pipe shall conform to Class 4, Wall B, of ASTM Specifications C-76 of AASHO Designation M-170. Strengths for corrugated metal pipe shall be as required by the New Jersey Department of Transportation Standard Specifications, current edition and amendments.

Box culverts shall be designed in accordance with AASHO recommendations.

Stormwater management.[1]

[Amended 5-9-2006 by Ord. No. 06-03]

Submission of plan required. For all new construction for which a building permit is required, as well as for all soil removal for which a soil removal permit is required, within the Borough of Alpha, a storm water management plan must be submitted to the Borough Engineer for review and approval as provided for in Subsection C(4) prior to any commencement of construction.

Contents of plan. Every stormwater management plan submitted to the Borough Engineer shall include the following data:

The name and address of the applicant.

The lot and block numbers of the site as shown on the current Borough Tax Map.

The location of the site within the watershed(s) as shown on a topographic map.

The location and description of significant natural and man-made features on and surrounding the site, including topography, steep slopes, all impervious surfaces, soil and drainage characteristics and presently existing stormwater runoff control devices, mechanisms or areas.

The size of the nearest culvert or storm sewer downstream of the discharge area and the proposed stormwater discharge from the site.

The location and description of any proposed changes to the site, whether of a permanent or temporary nature, with particular attention to impervious surfaces and interception of presently dispersed flow which may affect the capacity of the soil, vegetative cover and drainage ways to absorb, retard, contain or control stormwater runoff.

The designation of critical or other areas to be left undisturbed, shown in sufficient detail to be accurately marked and identified on the land.

(h)

The approximate computation of the total stormwater runoff before and after the disturbance of land and/or construction of impervious surfaces.

(i)

Any proposed temporary and permanent stormwater management measures.

General guidelines. The stormwater management plan shall adhere to the following general principles:

The rate and velocity from the site following completion of the planned development shall not exceed that which occurred in previous undisturbed ground cover.

Maximum use shall be made of presently existing stormwater runoff control devices, mechanisms or areas, such as existing berms, terraces, grass waterways, favorable hydrologic soils, swamps, swales, watercourses, woodlands and floodplains, as well as any proposed retention structures.

Whenever practicable and when permitted by the zoning provisions of this chapter, the construction should aim to reduce the total area of impervious surface and not increase the runoff flow rate.

Evaluation shall be made of the nature of the subwatershed(s) of which the site is a part, the receiving stream channel capacities and the points of concentration structure as shown on a Borough map showing roads, streams, culverts, bridges, and the existing drainage Master Plans.

To the greatest possible extent, the plan shall avoid the concentration of flow and shall provide for dissipation of velocities at all concentrated discharge points.

Reestablishing vegetation cover shall be in accordance with Standards and Specifications for Soil Erosion and Sediment Control in New Jersey, current edition.

The plan shall establish a time schedule for temporary and permanent stormwater management measures during construction, to include seeding and establishing sod in grass waterways.

(4)

Review of plan. The stormwater management plan shall be submitted to the Borough Engineer for review and approval. If the applicant is before the Planning Board or Board of Adjustment, the Borough Engineer shall report to the appropriate agency whether he approves or disapproves the stormwater management plan. The agency may condition its approval of the applicant for site plan, subdivision or variance upon approval by the Borough Engineer of the stormwater management plan. In the event that the applicant disagrees with the decision of the Borough Engineer regarding the stormwater management plan, the applicant may take an appeal to the Board before which the application is being considered.

(5)

Design standards. The Borough Engineer shall utilize the following design standards in reviewing the stormwater management plan:

The stormwater management design for all residential and nonresidential development shall be in conformance with the Stormwater Management Rules (N.J.A.C. 7:8) of the State of New Jersey and the New Jersey Stormwater Best Management Practices Manual published by the NJDEP dated April 2004 and amended thereafter. These rules set forth the required components of regional and municipal stormwater management plan and establish the stormwater management design and performance standards for new (proposed) development. The design and performance standards for new development include groundwater recharge, runoff quantity controls, runoff quality controls and Category One buffers. Details of the performance standards can be found in Subchapter 5 of the Stormwater Management Rules.

All facilities are to be designed in a manner to retard velocities at the outfall and provide stream channel protection.

When a natural drainage pattern is necessarily intercepted, as by a street, this shall be provided for by proper engineering means.

All structures and land treatment practices shall conform to Standards and Specifications for Soil Erosion and Sediment Control in New Jersey, current edition.

All water-carrying structures and/or retention areas shall be completed and stabilized prior to diversion of water to them.

Prior to developing the stormwater management plan, there shall be an inventory of the site showing all existing natural and man-made drainage related features. These shall be incorporated in the plan to the greatest possible extent in accordance with their functional capability.

Drainageways and watercourses which normally carry or receive stormwater runoff shall not be overloaded with increased runoff, sediment or other pollution resulting from disturbance of soil and vegetation incident to development, construction or other activity.

(h)

Due consideration shall be given to the relationship of the subject property to the natural or established drainage pattern of the subwatershed(s) of which it is a part.

(6)

Factors to guide plan review. The Borough Engineer's review of the stormwater management plan shall be guided by but not be limited to the following factors:

The suitability of the applicant's proposed stormwater management measures, devices and planning techniques, whether involving on-site or off-site measures, or some combination thereof, in respect to the total stormwater runoff, velocities and rates of discharges which the applicant's proposed construction or land disturbance may generate.

Existing topography, present vegetation and soil factors, subject to field verification.

Groundwater recharge and discharge areas and wet soils, as shown on the United States Department of Agriculture Soil Conservation Service Map, "Alluvial, Poorly Drained and Somewhat Poorly Drained Soils."

Groundwater quality, as determined by chemical and biological analysis, as required by the Borough Engineer.

Soil characterization from the surface to the groundwater level.

The quantity of available groundwater.

Wastewater disposal and its effect on groundwater quality.

(h)

The seasonal high groundwater table.

(i)

The design storm.

(j)

The natural drainage flows and patterns in the subwatersheds affected by the plan.

(k)

Any existing land uses in both the immediate area and in the surrounding drainage region.

(l)

Any other applicable or relevant environmental and resource protection ordinances in effect.

(7)

Implementation and enforcement.

Building permits. No building permit shall be issued by the Building Inspector without an approval of the stormwater management plan by the Borough Engineer.

Inspection.

[1]

The applicant shall bear full and final responsibility for the installation and construction of all required stormwater runoff control measures according to the provision of his approved plan and this section. The Borough Engineer shall inspect the site during its preparation and development to ensure that all stormwater management measures have been constructed in accordance with the provisions of the applicant's approved plan under this section.

[2]

The Borough Engineer shall make periodic site visits after project completion to assure that all parts of the plan have been complied with.

Certificate of occupancy. No certificate of occupancy shall be issued by the Building Inspector unless and until receipt of a certification by the Borough Engineer that the construction complies with the approved stormwater management plan.

(8)

Special requirements for single-family dwellings. All single-family residential dwellings are exempt from the requirement in this section of submission of a stormwater management plan. However, in all such dwellings, house leaders must be connected into a Borough drainage facility or Borough drainage way if possible and approved by the Borough Engineer. This section shall in no way be construed as limiting the power of the Board of Adjustment or the Planning Board to require submission of information and/or plans relating to stormwater management.

(9)

Violations and penalties.

Any person violating the provisions of this section shall, upon conviction thereof, be subject to a fine not exceeding $500 or imprisonment in the county jail for a term not exceeding 90 days, or both.

Any person convicted of a violation of any provision of this section shall be liable for the cost of correcting said violation.

Editor's Note: See also Ch. 340, Stormwater Management.

Design criteria not covered herein.

Criteria not incorporated herein necessary for design shall be based on recommendations incorporated with Hydraulic Engineering Series circulars published by the Federal Highway Administration and ASCE Publication, Design and Construction of Sanitary and Storm Sewers, current edition, and as approved by the Borough Engineer.

Design methods prepared by the Soil Conservation Service may be used for drainage design with the approval of the Borough Engineer.

Subsurface disposal. Due to the dolomitic limestone geologic formation underlying the Borough of Alpha and the significantly increased possibility for the occurrence of sinkholes when stormwater is disposed of by subsurface means rather than to a surface watercourse, and due to the potential for serious property damage and the endangerment of the public health, safety and welfare associated with the occurrence of sinkholes, the disposal of stormwater by subsurface means is hereby prohibited.

§ 350-20 Utilities.

Sanitary sewage disposal.

Where a public sanitary sewer system is accessible, each lot within a subdivision shall be provided with sewage disposal facilities by the required extension of sewer mains and connections thereto. All such installation of sewer mains and connections shall be constructed in conjunction with the specifications and requirements of the Borough of Alpha and shall be subject to the approval of the Borough Engineer.

Where a public sanitary sewer system is not accessible and where installation of sewer lines and a sanitary sewer disposal plant is not required, the subdivider may be required by the Planning Board to install within the subdivision a complete sewerage system, including provision for connection thereto at each lot, provided that there is reliable information to indicate that connection of the development to a public sanitary sewerage system can be anticipated within a reasonable period of time. Under such circumstances, the subdivider shall be required to install individual sewage disposal systems for each lot at the time improvements are erected thereon. All such individual sewage disposal systems shall be constructed in accordance with the requirements of the State Department of Environmental Protection and the Board of Health of the Borough of Alpha, and all such sewerage systems shall be constructed in accordance with the requirements of the Borough of Alpha and shall be subject to the approval of the Borough Engineer. The installation shall include house sewer service connections to the curbline, at which point the same shall be capped.

Percolation tests. Where the provisions of Subsection A(2) above are implemented, the subdivider shall furnish to the Planning Board satisfactory proof by in the form of soil testing in accordance with the requirements of Chapter 140 that the substrata under each lot is sufficient to support a properly functioning individual sewage disposal system conforming to the requirements of Chapter 140.[1]

[1]

Editor's Note: Former Ch. 140, Sewage Disposal Systems, Individual, was repealed at time of adoption of Code (see Ch. 1, General Provisions, Art. I).

Water mains.

When a public water supply system is accessible for the subdivision, each lot within the subdivision shall be provided with water supplied by said water supply system. All facilities for said system shall be installed pursuant to and in accordance with the provisions of the ordinance regulating the distribution and use of water of the Borough of Alpha[2] and all ordinances pertaining thereto, under the supervision of the Borough Engineer.

[2]

Editor's Note: See Ch. 403, Water and Sewers.

In the event that a public water supply system is not available to supply the proposed subdivision, the subdivider shall construct a private water supply system in such manner that an adequate supply of potable water will be available to each lot within the subdivision at the time improvements are erected thereon and so that such system can be incorporated within the public supply system when and if it shall become available. The water treatment and distribution system shall be constructed and installed in conformity with the ordinance regulating the distribution and use of water of the Borough of Alpha,[3] under the direct control and approval of the Borough Engineer. The adequacy, healthfulness and potability of the private water supply system shall be subject to the approval of the Alpha Board of Health and the State Department of Environmental Protection, when such approval is required.

[3]

Editor's Note: See Ch. 403, Water and Sewers.

Fire hydrants shall be installed in all subdivisions when a central water supply exists. Fire hydrants shall be of the type approved by the Borough of Alpha and shall be placed and installed in accordance with the standards of the Borough of Alpha. Such installation shall be subject to the inspection and approval of the Borough Engineer.

Electric, telephone and cable television.

Except as otherwise provided in the regulations of the Board of Public Utility Commissioners, in all major subdivisions, electric, telephone and cable television facilities shall be installed underground.
