Street Construction, Sitework and Restoration (Section 600) To remain consistent with changes made to the WisDOT Specifications, Section 607 of the City Specifications has been re-written to refer to dense graded base instead of crushed aggregate base course, to adopt the WisDOT gradation requirements, and to correct the reference to the pertinent WisDOT section number. In making the change to dense graded base, references were also changed in Standard Detail Drawings 600-5, 600-7, 600-9, 600-10, 600-12 (now 600-13), and 600-13 (now 600-14) and to paragraphs 609.G(2), 609.H(2), 613.B(2), and 613.C(9).

The previous detail drawing incorrectly showed it as 1.5 feet.

The detail note has been changed to effect this requirement. Standard Detail Drawings 300-3, 300-4, 300-7, 300-8 There has been some confusion about which side of the plastic adjusting rings should be placed to face up. The detail drawings have been revised to label the top and bottom sides of the rings.

Minimum spacing of corporation stop taps from water main joints has been changed to 24”, consistent with changes to water main specifications above.

Standard Detail Drawing 600-11 A new detail drawing has been added to detail the longitudinal joints to be used for asphalt pavement, consistent with DOT specifications. The detail drawing also shows end and edge joints to be used for asphalt overlay projects.
