NORTON: Decisions made this week will have profound effects on the city for years to come but the costs and consequences remain in doubt.On Monday, City Council held a strident, three-hour session that produced a major step toward starting the $8 million Nash Heights sewer project, with the hiring of outgoing Administrator Rick Ryland as a consultant/contractor and a deal to compensate Mayor Mike Zita for temporarily taking Ryland’s duties.Hours later voters went to the polls and elected four new councilmen who have been critical of the sewer project and the city administration.Council’s action authorized Zita to sign a deal with the EPA to commit to the controversial sewer project that gives the city two years to complete the work.
