  • When same size pipes meet at a storm structure, the downstream pipe invert shall be at least 0.1 feet below the upstream pipe inverts.
  • When pipe sizes increase in a storm structure, the inside top elevations of the upstream and downstream pipes shall match. However, a larger drop in pipe invert elevations is acceptable when necessary.
  • All abandoned storm sewer shall be removed from the ground.
  • Storm sewer shall have a minimum of 12 inch cover above top of pipe and shall never have the top of pipe into the pavement gravel base course or pavement.

1.10    When a project requires connecting to a City of Madison or MMSD sewer, the A/E is responsible for determining the permitting/approval requirements, designing systems that meet those requirements, and obtaining the permit/approval.

2.           Pipe Culverts

2.1        Material for new or replaced culverts, on or off campus, shall be RCP.

3.           Storm Drainage Structures, Frames, and Covers

  • Castings:

3.1.1   All storm drainage manholes lids shall have “storm” cast onto them. Casting is the same; however, Neenah’s standard lid with the text shall be used. The lids shall be Type B, self sealing, non-rocking, with concealed pick hole, and are typically not gasketed. There should be no additional cost of these lids over the standard type B lid.

3.1.2   Use Neenah casting R-3067 (per DFD Standard) for storm curb inlets in both 18 inch and 30 inch Curb & Gutter except as stated below.

3.1.3   Use Neenah R-3170 casting for storm curb inlets in 18 inch curb & gutter when it runs parallel to a bike lane or abutting concrete pavement.  This is a smaller inlet so it may require additional inlets.

3.1.4   Use Neenah Casting R-3067 for storm curb inlets in parking lots.

3.1.5   Since most storm inlets drain to the lake, then all inlets shall have a cast logo on it that says “Dump No Waste Drains to Lake”

3.1.6   Manhole castings shall never be in the curb & gutter.

3.1.7   Round castings, rather than square, shall be used for catch basins, pavement inlets, and yard inlets unless approved by UW FP&M.

  • Exterior trench drain castings shall be cast iron.
  • Structures:
  • Integral steps shall not be included in storm structures.

3.2.2   Inlet detail drawings shall be based on City of Madison Type H inlet standards.

  1. Stormwater Management Facilities
  • The design consultant is responsible for identifying and obtaining all new and existing stormwater management permits, approvals, and agreements issued by regulatory agencies. Consultant shall provide designs and plans that comply with all said permits, approvals and agreements.

  • Sustainable stormwater facilities that promote filtration and/or infiltration and reduce the amount of water entering storm drains are strongly encouraged.
  • Examples include, but are not limited to, rain gardens, bio-retention areas, cisterns, green roofs, pervious pavers, porous surfaces, dense tree canopies, etc.
  • Facilities that promote infiltration shall be at least 20 feet from building foundations to reduce risk of water entering basements.
  • Where these facilities incorporate vegetation and are designed such that water may eventually enter Lake Mendota or the Lakeshore Nature Preserve, the plants selected shall not be on the Wisconsin DNR Invasive Species list and shall not spread aggressively. Native plant species shall be used.
