A motion was made by Mr. Anderson, seconded by Mr. Rector and passed
unanimously to approve the minutes of the February 13, 1992 meeting.
The public hearing was opened on Appeal No. P92-1. The appellant was
Eugene C. Urban, representing Bay Area Healthcare Group, Ltd. appealing
interpretations of the Plumbing Code, Sections 704.2.3 and 1303.3 regarding
Pipe Cleanout Spacings and Drainage Pipe Installation Slopes, which address
the drainage and cleanout requirements for building sewer installations.
Mr. Derwood Anderson abstained from the discussion and voting due to
a possible conflict of interest, and excused himself from the Board.
Mr. Lelland Kirbow, acting Chief Plumbing Mechanical Inspector,
described the appeal to the Board, explaining the Code sections in question.
He stated that the design proposed did not comply with the code criteria ii
regarding the spacing of clean outs not to exceed 75 feet, and a drainage z
installation slope of (1/8") one-eighth inch per foot. He stated that the
staff supports the Code requirements. z

requirements for cleanouts, because their design provided for manholes in
accordance with the State Health Department criteria. Mr. Urban then
discussed the distinction between a building sewer and a private sewer, and
requested that the 75 foot cleanout spacing requirement be waived in that a
private sewer system was provided with manholes at a 500 foot spacing.
Mr. Gonzalez, Building Official, explained that the design was a good
Civil engineering design that under normal circumstances would be accepted
if it were being dedicated to the City and placed in platted Utility
easements. In the project in question, no dedication was taking place and
no easements were in existence.
Mr. Philip Skrobarczky, Project Contractor, also spoke on behalf of the
Bay Area Healthcare Group, Ltd. Mr. Skrobarczky provided historical
comments regarding other similar projects.
After a lengthy discussion, a motion was made by Mr. Larson, and
seconded by Mr. Rector, that alternate flowrates (or the fall) be allowed
on the normally recognized civil proportion of the project, from the
property line to the building, as permitted on larger projects, with eight
(8) members voting for, and Mr. Murray voting against. Mr. Gonzalez
clarified that this motion was applicable to this particular project only.
Mr. Larson made a motion, seconded by Mr. Rector, and passed
unanimously to require the building sewer line to have two-way cleanouts at
the building, and require manholes spaced at 300 foot centers maximum.
The next item on the Agenda was the discussion and consideration to
recommend updating the Corpus Christi Plumbing Code, to include the 1991
editions of the Standard Plumbing and Gas Codes with local amendments.
A motion was made by Mr. Rector, seconded by Mr. Anderson, and passed
unanimously to recommend allowing as an alternate the use of manholes spaced
at a distance not to exceed 300 feet on horizontal drainage pipes which
exceed 4 inches in diameter, in lieu of the requirement to provide cleanouts
at distances not to exceed 75 feet. Additionally, to include that the flow
rate in the pipe be not less than 2 feet per second.
In a subsequent motion Mr. Larson moved, seconded by Mr. Sutton,
and passed unanimously to omit the testing of the Building Sewer in section
417.2.5.
Mr. Sutton made a motion, seconded by Mr. Murray and passed
unanimously to amend section 704.2.1 of the Plumbing Code to read "Each
horizontal drainage pipe shall be provided with an accessible clean out at
the upstream end of the pipe.", and that item 7 currently in code under the
exceptions be removed.
