This sign appeared today on Tuscany at Muirkirk. I called DPW&T Customer Service and they said that vacuum leaf collection is scheduled in the Montpelier Hills "subdivision" on or about Wednesday January 21 for county roads Tuscany and Hermosa, but not for county road Apache Tears because, they said, Apache Tears is not listed as as part of the Montpelier Hills subdivision as they have it -- something about Apache Tears being on the other side of Muirkirk. Hmmm.
At the web site, they list the vacuum leaf pickup schedule only by community -- not by individual streets. And even there, Montpelier Hills is not listed explicitly -- perhaps falling under "Laurel" or "Northern Prince George's County".
In any case, only county roads are scheduled, not private streets.
That's all i know.
