F. Nonconforming signs.
(1) Any signs now in existence, the erection or placing of which would be prohibited hereunder, may be continued on such building, structure, lot or land so occupied. However, at no time shall such sign be altered, rebuilt, enlarged, extended or relocated unless such action changes a nonconforming sign into a conforming sign as provided herein.
(2) The failure to keep a nonconforming sign painted or in good repair for a period of six (6) months shall constitute abandonment, and such sign may not be reused and must be removed.
G. Violations and penalties. Any person, firm or corporation who shall violate, disobey, omit, neglect or refuse to comply with any provisions of this chapter and Chapter 228 shall be upon a conviction thereof, subject to a fine of not more than fifty dollars ($50.), and each and every day that such violation continues shall constitute a separate and distinct offense.
H. Signs required by Planning Board. To facilitate the safe and efficient movement of traffic into and out of a site, the Planning Board may, as a condition of the site plan or subdivision approval, require the installation of specified directional, regulatory or advisory signs or pavement markings at designated locations on the site of the right-of-way. Such signs shall be of a size, color and design specified in accordance with the Uniform Manual of Traffic Control Devices.

A. Storage of articles to be displayed or sold on the premises of a commercial, industrial or other use shall be limited to a reasonable supply and, if stored outdoors, shall be stored in an area that is fenced or screened from view.
B. No goods, articles, appliances or vehicles shall be displayed or offered for sale beyond the front line of the buildings on such premises, or beyond the side line of the buildings of a corner premises.
A. Policy statement.
(1) All future development in Winslow Township shall utilize the best available technology to minimize offsite storm water runoff, increase on-site infiltration, simulate natural drainage systems and minimize off-site discharge of pollutants to ground or surface water and encourage natural filtration functions.
(2) The runoff control methods shall be to prevent the rate of off-site storm water runoff during the construction and operation of a development under selected storm conditions from exceeding the rate of runoff that would occur under the existing predeveloped conditions.
(3) All streets shall be provided with storm water inlets and pipes where same may be necessary for proper surface drainage. The system shall be adequate to carry off and/or store the storm water and natural drainage water which originates beyond the development boundaries and passes through the development, calculated on the basis of maximum potential development as permitted. No storm water 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 lands without proper and approved provisions being made for taking care of these conditions, including off-tract improvements.
B. General drainage requirements.
(1) When a developer or his engineer determines that it will be necessary to utilize design standards in addition to or other than those minimum requirements established herein, he is advised to consult with the Board Engineer prior to beginning his detailed design for review and approval of his proposed design standards. Standards utilized should generally be nationally recognized and in common use in this area.
(2) When the Board finds it necessary, they may waive any or all of the requirements established herein and may require additional information, in accordance with N.J.S.A. 40:55D-51.
(3) All development applications must be accompanied by a drainage area map and a drainage report which shall include all onsite and offsite areas contributing to the stormwater management system. Locations of soil borings and percolation tests, as required below, shall be shown on the development plans. Results of such tests shall also be shown on the plans or included in the drainage report. Drainage calculations shall include the results of soil borings and percolation tests.
(4) Percolation tests and reports:
(a) The percolation tests shall be at a depth of two (2) feet below the bottom elevation of the proposed recharge area.
(b) At least one (1) percolation test shall be performed at the site of each recharge area. More than one (1) test shall be required where the soil structure may vary or where large recharge areas are required. Preliminary tests for tracts involving more than one (1) recharge system may be made in the amount of one (1) per acre or as prescribed by the Board's Engineer. All the percolation tests shall be performed under the supervision of a licensed professional engineer, and the Planning Board Engineer or his authorized agent. The Board's Engineer or his authorized agent may waive the right to observe the percolation tests.
(c) Percolation tests shall not be made in test holes which have been allowed to remain open to the atmosphere for periods over three (3) days or in frozen ground. Tests shall not be made in filled ground unless the soil has been compacted or allowed to settle to the satisfaction of the Board's Engineer.
(d) Percolation tests shall be performed in accordance with the following procedures:
(i) Step 1: Prepare a test hole in the undisturbed soil at the depth intended to be used for recharge purposes, having horizontal dimensions of eight (8) inches to twelve (12) inches. Means may be used to protect the soil in the test hole from becoming clogged with silt and clay particles. Establish a fixed point at the top of the hole from which all shall be taken. Fill the hole with water and allow all of the water to drain into the soil.
(ii) Step 2: Fill the hole to a depth of approximately seven (7) inches. At a five (5) to thirty (30) minute time interval, depending on the rate of fall, record the drop in water level in inches during the time interval selected. Immediately refill the hole to the original depth of approximately seven (7) inches, and repeat the test using the same time interval and method. Repeat this procedure until the distance that the water has fallen in the time interval selected becomes approximately equal. (Steps 3 and 4 shall follow immediately.)
(iii) Step 3: Remove any silt accumulation or debris remaining in the hole.
(iv) Step 4: Refill the hole to a depth of seven (7) inches as quickly as possible and record the time required for only six (6) inches of the water to seep away. This time divided by size will be the percolation rate in minutes per inches.
(e) Reports shall be furnished to the Planning Board Engineer indicating the result of each percolation test in minutes per inch (including unacceptable rates), the date of the test, effect of recent rain or lack of rain, the apparent moisture of the soil prior to the test, the depth to groundwater when encountered, number of preliminary tests made to determine apparent saturation, the type or types of soil encountered, using the Unified Soil Classification System, or such other system as approved by the Planning Board Engineer, together with the thickness of each layer and all other factors affecting percolation test results.

For all basins with a surface area of one-half (1/2) acre or more, borings will be required at a rate of one (1) boring for each one-half (1/2) acre in addition to the initial minimum of two (2) borings per facility. All borings must extend ten (10) feet below the existing ground surface or to a depth of at least eight (8) feet below the depth of the proposed recharge facility, whichever is greater. Soil boring information shall be displayed on preliminary plans and shall include:
(i) The soil texture as described in the United States Department of Agriculture Soil Texture Classification System.
