The city's ordinance requiring developers to install secondary irrigation systems in residential and commercial developments was toughened Tuesday by the Centerville City Council.

The council removed a paragraph from its subdivision ordinance that appears to equivocate on the issue, trying "to put some teeth into the requirement," said Mayor Dean Argyle.The deleted paragraph stated that subdividers "shall make every effort to provide a secondary source of water" for irrigation.

The lead paragraph now says, "Secondary water for the purpose of irrigation shall be available to each lot in the subdivision and shall be provided" by the developer.

Some subdivisions in the city's north end were built without irrigation water, the mayor said, and the families living in them are finding it expensive to maintain lawns and gardens on city culinary water.

The council agreed the requirement may slow down development in some areas that either do not have water shares or are not served by a secondary system.

A memo from city planner Wilf Sommerkorn said, "There are a number of properties in north Centerville that do not have secondary water service available. To acquire such service, another reservoir and distribution system would have to be developed.

"This is not a cheap problem for the affected property owners to address.

"The effect of such a requirement will almost certainly be a slowing down of future development in Centerville," Sommerkorn warned.

"But this may be an acceptable consequence when considering the cost and quality of life for future Centerville residents who will ultimately live in these areas," he concluded.

Councilman Kent Lindsey said 1,500 water shares are still available for other parts of the city and the overall effect on growth will be negligible.

A section of the ordinance that exempts developments west of I-15 was maintained intact. No secondary irrigation lines run under I-15 to serve the area.
