APWA Plan No./

Specification Section Exception

215, 216, 221.1, 221.2, 225, 229.1 & 229.2

APWA Plan No’s. 221.1 and 221.2 are acceptable for use. APWA Plan

221.1, 221.2

When adverse slopes, right-of-way limitations, or existing obstructions occur, MSD Engineering may authorize deviations from the APWA apron/slope geometry.

Bituminous Concrete (asphalt) T-Patch thickness is 6” minimum for both residential and non-residential streets.

Bituminous Concrete (asphalt) T-Patch thickness is 6” minimum for both residential and non-residential streets.

2” mill and overlay are not required if:

• There is a known upcoming city Capital Improvement Project that will reconstruct or overlay the road within two (2) years.:

• Pavement surface has not been constructed or milled and overlaid within the previous seven (7) years.

• If length of T-patch is less than 300 feet and pavement surface has not been constructed or milled and overlaid within the previous three (3) years.

Steel tube is to be 12’ x 2” x 2”. Standard Plan 140 in this book applies in locations where sign is installed in concrete.

315.1, 315.2 & 316

Where APWA inlet plans refer to frame and grate per APWA Plan No.

308, contractor shall use Standard Plan 201 in this book, unless otherwise authorized by the MSD Engineer.

The use of pre-cast "knock-out" boxes in storm drain facilities may be authorized by the MSD Engineer, upon written request and provided the following conditions are met:

a) All other requirements of APWA Plan 332 - Precast Box, are still met.

b) Boxes shall have engineered design for AASHTO's HL-93 live load and shall be designed for lateral soil loads appropriate for the burial depth and conditions.

c) The thickness of concrete collars where the pipe enters box at the knockout face shall extend 6” to 9” from the exterior face of the box and shall cover the entire side of the structure with no less than 12” concrete all the way around the pipe. Collars shall have a minimum of four (4) #4 dowels tying the collar to the precast box and include a #4 rebar ring or square tie around the pipe.

d) Inspection and certification required on all precast boxes.

381 (Note 2A) - Use granular backfill borrow for common fill.

(Note 2B) - Use granular backfill borrow for common fill.

(Note 3A) - Minimum trench width is to be Pipe O.D. + 24” or (Pipe O.D. x

1.25)+12”, whichever is greater.

33 05 02

Public storm drain pipes and culverts shall be 15” dia.or greater RCP unless otherwise authorized by the MSD Engineer. Installation must follow manufacturer’s direction. Provide a minimum amount of 1’ cover over top of concrete pipes and 2’ cover over the top of pipes of other materials unless approved otherwise by manufacturer and MSD Engineer. Corrugated metal pipe and vitrified clay pipe are not allowed.
