b) Construction sites related to residential building that disturb a total of one acre or less of land.

c) Any construction activity the City Engineer or Designee deems to pose a unique threat to water quality, air quality, or public health or safety.

2. SWPPP shall be managed through the South Jordan City online storm water management system.

a) All BMP’s covering a storm drain inlet must contain an overflow feature for high volume rain/runoff events. Reference chapter 9 for acceptable inlet protection.

B. Storm Drain pipe in public right of way shall be minimum 18” RCP Class III or

HDPE.

1. Storm Drain lines shall be TV’ed by the contractors hired firm after placement and compaction of road base and prior to placing asphalt. This TV’ed disk shall be reviewed by the City designated Inspector. All areas found defective shall be repair to the satisfaction of the City Inspector before placing asphalt.

2. Storm drain caution tape shall be place and centered 1’ above the pipe.

3. Storm Drain lines will be TV’ed again, by City personnel prior to final bond release. All lines shall be cleaned by Developer prior to City performing the work. Any damaged pipe sections shall be repaired or replaced prior to final bond release.

C. Mirafi filter fabric may be required depending on the presence of groundwater, as determined by the City Engineer.

D. Manholes: Keep the manhole collar and cover down ¼” minimum and ½” maximum below finish asphalt grade. This will allow snowplows to pass over the top without hitting or damaging them, in the winter months.

Storm Drain manhole lid specifications: ASTM A 48-93, Class 35B Cast iron construction, machined flat bearing surface, removable lid with cleated surface and pick holes, H-20 highway load rating; lid molded with South Jordan City name and logo imprinted on lid; Provide Model A-1180 manufactured by D & L Supply., or acceptable equal. (See drawings section for detail.)

E. Developments must provide theft-resistant permanent installation of a City-approved storm drain marker at each storm water inlet. The marker item number is SD-SP, a stainless steel, painted blue, matte finish, embossed, fish symbol, optional serialization, 30 year warranty, with ¼” square hole made by Almetek Industries, Inc. Installation requires drive rivet and approved adhesive.

Lettering on the marker as appropriately follows:

“Only Rain in the Drain” markers installed anywhere storm water discharges to a retention or detention pond. (See drawings section for detail.)

F. A cleanout box with 24” silt trap is required before a private storm water system enters the City’s storm drain system. All private storm drainage conveyance systems shall also have a snout in place or an oil water separator system, approved by the City Engineer, before it discharges into the city system.

Facility’s that use large amounts of hydrocarbons such as gas stations, vehicle lube facilities, vehicle repair, and or paving facilities, shall be required to have a hydrodynamic separator in place prior to discharging into the city system, unless otherwise approved by the City Engineer or Public Works Director.

G. The first storm drain inlet box down gradient from a dumpster enclosure shall be required to have a snout and a 24” minimum silt trap, or larger as required by manufacturer recommendations for snout installation.

H. Silt traps are required for all catch basins, inlets, manholes etc. Silt traps shall be 12” deep, measured from invert of lowest pipe to bottom of box.

I. Boxes: During installation, grout boxes inside and out, and strip the forms from inside and outside of the boxes. Clean all dirt, rocks and debris from inside of the boxes. If using a pre-cast box, make sure to form a 6” collar around the outside of box with soil below pipe dug down and formed, and poured with concrete to engineering inspectors discretion. Before pouring concrete collar, contractor shall give engineering inspector 24-hour prior notice.

Inlet and combo boxes shall be precast or knockout boxes (unless otherwise approved by the City Engineer) and must accommodate an 18” x 48” frame and grate. Hooded grates are not allowed due to debris accumulating in the storm drain.

J. All onsite retention and detention basins shall be designed for a 100 year 24 hour storm event. The calculations and storm intensities used in the design must be submitted to the city for review and approval. Percolation rates are not allowed to be used in the capacity calculations for the storm water basins unless otherwise approved by the City Engineer. Retention basins shall be required to drain within 3 days of the storm event. Engineer shall provide a design that meets that criteria.

All calculations must be stamped and signed by a registered professional engineer.

K. For residential developments with underground storm water storage systems, storm drain calculations will not be allowed to include the void space in the gravel towards the total storage volume capacity. For commercial developments with underground storm water storage systems, storm drain calculations will not be allowed to include the void space in the gravel towards the total storage volume capacity unless approved by the City Engineer on a case by case basis. Projects allowed to count the gravel void space will need to show an acceptable overflow path for the storm water, in case the underground storage were ever to over top.

In addition, the storm water drainage system will require an approved separator unit to filter out sediment, oils and debris from the storm water prior to it entering the underground storm water storage chambers.

SECTION 6.2

REINFORCED CONCRETE PIPE

6.2.1 DESCRIPTION

This item shall govern for the furnishing and installing of reinforced concrete pipe and materials for construction.

6.2.2 MATERIALS

A. Pipe Type:

Shall be minimum 18”, RCP Class III.

B. Bedding and Backfill (RCP):

A City specified material (A-1-a to A-2-7 under AASHTO Soil Classification system) will be used for trench backfill. Place 1”minus gravel 6 inches under pipe and up to spring line (no squeegee or chips). Tamp underneath the haunches to prevent settlement. Compaction of 96% modified proctor is required.

SECTION 6.3

POLYPROPYLENE PIPE

6.3.1 DESCRIPTION

This item shall govern for the furnishing and installing of all Polypropylene Pipe, materials for construction and all related connections and fittings.

6.3.2 MATERIALS

Unless otherwise specified on the plans, pipe and joint fittings shall conform to the following:

A. Eighteen through 60-inch (460 through 1500 mm) pipe shall be smooth interior and annular exterior corrugated polypropylene (PP) pipe meeting the requirements of ASTM F2881 or AASHTO M330, Type S, for respective diameters. The pipe supplied shall be watertight as defined in the joint performance requirements of this specification.

B. Virgin material for 18 through 60-inch pipe and fitting production shall be an impact modified copolymer meeting the material requirements of ASTM F2881 and AASHTO M330, for respective pipe diameters.

C. Joints shall be installed in accordance with manufacturer’s installation instructions. All Bell-and-Spigot pipe joints shall be thoroughly cleaned. Joint lubricant, supplied by the manufacturer, shall be liberally applied to entire interior of bell and gasket on spigot prior to assembly. Watertight joints shall be bell-and-spigot meeting the watertight requirements of ASTM F2881. Gaskets shall be made of polyisoprene meeting the requirements of ASTM F477. Gaskets shall be installed by the pipe manufacturer and covered with a removable wrap to ensure the gasket is free from debris. A joint lubricant supplied by the manufacturer shall be used on the gasket and bell during assembly.

D. Fittings shall conform to ASTM F2881, with the exception of meeting the watertight joint performance requirements of ASTM D3212. Bell & spigot connections shall utilize a spun-on, welded or integral bell and spigot with gaskets meeting ASTM F477.

6.3.3 INSTALLATION

Installation shall be in accordance with the product manufacturer’s published installation guides and these instructions.

A. All pipe and fittings shall be delivered to the site and unloaded with handling that conforms to the manufacturer’s instructions for reasonable care. Pipe shall not be rolled or dragged over gravel or rock during handling. The Contractor shall take necessary precautions to ensure the method used in lifting or placing the pipe does not induce undue stress fatigue in the pipe.

B. Bedding and Backfill:

Bedding shall be gravel or compacted road base as per South Jordan City standards. A stable and uniform bedding shall be provided for the pipe and any protruding features of its joint and/or fittings. The middle of the bedding, equal to one-third of the pipe outside diameter, shall be loosely placed while the remainder shall be compacted to a minimum of 96% of maximum density per AASHTO T99, or as shown in the plans. Pipe bedding shall be a minimum of 4” – 6” in thickness. The bedding surface for the pipe shall provide a firm foundation of uniform density throughout the entire length of the pipe. Backfill shall be placed in layers of 8” loose lift thickness and brought up evenly and simultaneously on both sides of the pipe to an elevation not less than one foot (1’) above the top of the pipe. Each layer shall be thoroughly compacted; backfill shall be compacted to a minimum compaction level of 96% Density (Modified Proctor).

C. Trench Widths - Where trench walls are stable or supported, provide a width sufficient, but no greater than necessary, to ensure working room to properly and safely place and compact haunching and other embedment materials. The space between the pipe and trench wall must be wider than the compaction equipment used in the pipe zone. Minimum width shall be not less than the greater of either the pipe outside diameter plus 16 in. or the pipe outside diameter times 1.25, plus 12 in. In addition to safety considerations, trench width in unsupported, unstable soils will depend on the size and stiffness of the pipe, stiffness of the embedment and in-situ soil, and depth of cover.

D. Dewatering - Do not lay or embed pipe fittings or drainage structures in standing or running water. At all times prevent runoff and surface water from entering the trench. When water is present in the work area, dewater to maintain stability of in-situ and imported materials. Maintain water level below pipe bedding and foundation to provide a stable trench bottom. Use, as appropriate, sump pumps, well points, deep wells, geofabrics, perforated underdrains, or stone blankets of sufficient thickness to remove and control water in the trench. When excavating while depressing ground water, ensure the ground water is below the bottom of cut at all times to prevent washout from behind sheeting or sloughing of exposed trench walls. Maintain control of water in the trench before, during, and after pipe system installation and until embedment is installed and sufficient backfill has been placed to prevent flotation of the pipe, fitting, or drainage structures. To preclude loss of soil support, employ dewatering methods that minimize removal of fines and the creation of voids in in-situ materials.
