State law requires cities to present bond issue propositions so that voters can grasp how much money would be devoted to a single purpose.Fort Worth has divided its $292 million bond ballot for the May 10 election into seven propositions. The Star-Telegram Editorial Board has studied each of them to present recommendations for voter consideration. Propositions 1-5 were discussed earlier this week in editorials available on star-telegram.com.Early voting starts Monday.Proposition 6The city proposes to issue $15.08 million in bonds devoted to two new service centers to house city crews and equipment.A new center in north Fort Worth would be for transportation/public works crews and equipment maintenance staff. The estimated cost is a little more than $14 million.North Fort Worth is a rapidly expanding part of the city, and the goal is to put crews and equipment closer to where they work. That, the city staff says, should increase operational efficiency, reduce travel time and help control fuel costs.Another $780,000 would be used for design work on a new equipment service center in the Holly Water Treatment Plant compound just west of downtown along the Clear Fork Trinity River. When built, the center would service water department and other city vehicles. Funding beyond the design stage will have to come from other sources.The Star-Telegram Editorial Board recommends voting for Proposition 6 in the Fort Worth bond election.Proposition 7The final item on the bond ballot would devote $2.35 million for animal care and control.The Chuck Silcox Animal Care and Control Center at 4900 Martin St. near the Southeast Loop 820/U.S. 287 interchange would be renovated and expanded at a cost of $1 million. About 100 new kennels and enhanced quarantining/segregation capabilities would be added.Another $1.3 million would be used to build a new animal care and control center in north Fort Worth, housing about 100 animals.The Star-Telegram Editorial Board recommends voting for Proposition 7 in the Fort Worth bond election.
