Maybe a complex problem, but there is often standing water (rain or shine, but especially when it's been raining) on the sidewalk and the street in the block just east of Walnut on the south side of 12th Street. .
Last year, the section of the sidewalk at Washington and Cottage Grove was replaced, but the workers left a trench in the road that collects water and breeds mosquitos. I couldn't help but notice when similar work was done this summer on 10th street and a layer of pavement was laid alongside the sidewalk to fill the trench there. Probably just an oversight but it'd be nice to get this job completed.
