Markeley Lane Extension

Markeley Lane Extension

Travis Unified School District is proposing to construct an ~36 ft wide private roadway with two bicycle lanes and one 6 ft wide sidewalk within a 60 ft wide access easement and a storm water detention basin. The proposed roadway would extend from the inersection of Markeley Lane and De Ronde Drive east and end with a cul-de-sac adjacent to Center School, for a total roadway length of ~1,500 ft. The roadway would involve only minimal grading over most of the length, except for a bridge over the Union Creek Bypass Channel and at the cul-de-sac. The Union Creek Bypass Channel would be spanned with a clear-span concrete bridge that would have fill behind its concrete headwalls, but should not have any jurisdictional impacts to the channel. A temporary stream diversion may be necessary during construction. The eastern end of the cul-de-sac would be excavated ~8 ft into the hillside. An earthen ditch would have maximum excavation and fill of ~4 ft. Overflow from the detention basin would discharge to the nearby Union Creek Bypass Channel. The estimated maximum holding time for water in the detention basin would be 24 to 36 hours.
