THE PROP. 1 DITCH INCENTIVE If Houston voters pass Proposition 1 in November, the average homeowner will pay about $5 a month to the city’s new drainage and street-renewal fund, Mayor Parker announced today. Commercial properties and homes on curb-and-gutter streets would be assessed 3.2 cents per sq. ft. of hardscape (including building footprints, driveways, porches and parking lots) per year. But owners who live on streets with open ditches would only have to pay at a 2.6-cents-per-sq.-ft. rate. That’d save the average ditch-side homeowner a whopping $11.40 a year. The assessment rate would be fixed for 10 years, and require a two-thirds vote from city council to be raised after that. Reporter Miya Shay has the calculations. [abc13; previously on Swamplot]
