Review of Minutes 36 Commissioner Katz moved, seconded by Commissioner Heidbrink, to approve the minutes of the February 20, 37 2013 Architectural Control Commission (ACC) meeting without corrections. On a voice vote, the motion 38 unanimously carried. 39 40 4. Review of 2012 International Plumbing Code/2004 Illinois Plumbing Code and Local Amendments 41 Director Poupard explained that the plumbing code framework was unique. The State of Illinois established a 42 mandatory State Plumbing Code that all communities must follow. Municipalities may adopt more stringent 43 standards, but may not reduce the state requirements. In the past, Northbrook adopted the International 44 Plumbing Code (IPC) and amended the IPC, as necessary, to work with the state code. Director Poupard 45 recommended following this same approach in adopting the 2012 IPC and modifying the code, as necessary. He 46 also provided commissioners with a matrix highlighting the plumbing regulations of surrounding communities.  Page 2 Minutes of the April 3, 2013 Architectural Control Commission Meeting 1 Inspector Reupert then lead the ACC in a review of Chapter 6, Article IV of the Northbrook Municipal Code, with 2 staff-suggested modifications. He explained that the suggestions were primarily intended to clarify current “gray 3 areas,” and, thereby, “move jobs along faster.” Specific ACC recommendations and comments were as follows. 4 5 Sec. 6-71 and Sec. 6-72 6  The ACC recommended that relevant dates be updated to read “2012.” 7 8 301.3 Connections to the sanitary drainage system. 9  The local amendment was perceived as an unnecessary administrative detail and, therefore, the ACC 10 recommended deletion. 11 12 Renumbered 305.4 Freezing. 13  “or heat…below grade” was perceived as unnecessary and, therefore, the ACC recommended deletion. 14 15 307.7 Stack plumbing wall. 16  “consist of…5 ½ nominal width” was perceived as unnecessary and, therefore, the ACC recommended 17 deletion. 18 19 309 Flood Hazard Resistance through 310.5 Urinal Partitions 20  The Village Flood Hazard Ordinance rendered the local amendments unnecessary and, therefore, the 21 ACC recommended deletion. 22 23 312.9 Inspection and Testing of Backflow Prevention Assemblies. 24  The local amendment was perceived as unnecessary and, therefore, the ACC recommended deletion. 25 26 312.10.2 Testing. 27  “pressure vacuum breaker” and “and spill resistant…assemblies” were perceived as unnecessary and, 28 therefore, the ACC recommended deletion. 29 30 Table 403.1 Minimum number of required plumbing facilities. 31  To enhance sanitary practices and clarify the local amendment, the ACC recommended deleting “When 32 the public washrooms…water closet requirement” in re-lettered footnote “i.” Commissioners also 33 recommended that staff “clean-up” the remaining footnote to coincide with the relevant international 34 code. 35 36  In re-lettered footnote “l,” the ACC recommended specifying that, where possible, sill cocks or wall 37 hydrants should be located on opposing elevations of the structure. 38 39 410.1 Handicap drinking fountain. 40  Following discussion, the ACC requested that staff consider tweaking the local amendment to include 41 bottled water installations in cases of considerable hardship (e.g., where significant plumbing work 42 would be necessary to comply with the amendment). 43 413.5 Waste lines. 44 45  The local amendment was perceived as unnecessary and, therefore, the ACC recommended deletion.  Page 3 Minutes of the April 3, 2013 Architectural Control Commission Meeting 1 2 417.5 Shower floors or receptors. 3  The ACC perceived the proposed local amendment as necessary and, therefore, recommended adding 4 the amendment. 5 6 417.5.1 Support through 421.4 Suction fittings 7  The ACC recommended adding the relevant IPC language for clarification. 8 9 421.6 Whirlpool enclosure through 427.1 Floor Sinks Approval 10  The ACC recommended adding the relevant IPC language for clarification. 11 12 504.7 Required pan. 13  The ACC recommended adding the staff-suggested language, “and shall extend full size...as the water 14 heater.” 15 16 504.7.1 Pan size and drain. 17  The ACC recommended adding the relevant IPC language defining pan depth. 18 19 [E]505.1 Unfired vessel insulation. 20  The ACC recommended including the relevant energy code requirement. 21 22 Table 605.3 Water Service Pipe. 23  The ACC recommended deleting “Solder” and “ASTM B 32” because this material and standard, 24 respectively, were included in the state code. 25 26 Table 605.4 Water Distribution Pipe. 27  Following discussion regarding the relative merits of polypropylene, including viewing a polypropylene 28 plastic pipe sample, and in an effort to remain competitive with surrounding communities, the ACC 29 recommended adding “Polypropylene (PP) Plastic Pipe or Tubing” and “Stainless Steel Pipe (Type 30 304/304L);

Director Poupard 2 responded that the code dictated contractor license revocation for repeated violations and he noted that the 3 ACC might serve a similar role as the Electrical Commission for repeated, egregious plumbing violations. 4 5 Chairperson Schwall also inquired about charging additional fees for instances that require significant staff time, 6 to which Director Poupard responded that the Village was exploring this issue and currently penalized offending 7 contractors. The ACC discussed the appropriate role of the general contractor in such instances. 8 9 8.
