Copies of "proposed" ordinance wording as presented by Jim Dougherty 9, 2009. Review of code information and requirements for basements. STAFF SUMMARY Background: The Board has had several discussions regarding below grade structures while ZPC was also discussing the same. Attached is a copy of proposed ordinance wording changes as proposed by Jim Dougherty. Purpose: Discuss ZPC consensus. Review code information on basements. 1 Regulation of basements and other "below-grade spaces" 7-09-09 ZPC Position forward to BSC Issue ZPC Consensus BSC Consensus Definition of "below Defer to definition of grade space" basement in the IRC Size limit No limit Counts as framed area No Counts as a story No Height limit None Plumbing fixtures Allowed per plumbing (does not apply to code requirements lines) Use restriction None Number of emergency Defer to the IRC egress paths (EEP's) EEP directly to Defer to the IRC outdoors Indoor swimming pool Not in ZPC purview in below grade space Excavation limits No projection or (ratio of distance from encroachment into property line to depth regulated yards of hole) (setbacks) allowed at any time during construction or at finished pr duct.

In the Public Works Facility Lunchroom Located adjacent to 3825 Milton West University Place, Texas 77005. The subjects of the meeting are as follows: 1. Notices. Rules. Etc. Bryant Slimp stated the alternate voting members were as follows: Muddy McDaniel, Frank Griffin, Gerry Spedale and Dave Miller. 2. Meeting Minutes. The minutes from the February 5, 2009 were approved. 3. Docket Number 09-01 restardine property at 3936 Bellaire Blvd. West University Place. Texas. BSC granted a variance to A & O Lamp Co to replace the canopy mounted signage that was existing before Hurricane Ike. 4. Basements. There was general discussion regarding the subterranean structures handout that was submitted from James Dougherty. BSC approved the amendments with the following exceptions: the basement must be under the foot print of the house; the setbacks for the basement should be determined by the angle of repose x 1.5 the depth of the basement and the only entrance to the basement must be from inside the house. 5. Construction Codes. BSC approved the amendment to appendix P of the IRC proposed by the Fire chief and Fire Marshall. There was general discussion regarding the approval of adopting the International Residential Code, Mechanical, Plumbing and fuel gas codes with the Local Amendments. BSC was concerned there could be a conflict in the current local amendment that disallows PEX piping and the approval of the residential fire sprinkler systems which will be installed in plastic pipe. BSC asked staff to review the materials allowed in the residential fire sprinklers and comment on any potential conflict in material usage. BSC also asked staff to look for any other potential conflicts in the new code adoptions and local amends. • 0 Amendment relating to basements and other "below-grade" spaces" 3-9-09 Add a new definition as follows: Below-grade space.
