Prior to design and construction, this steep and narrow ½ mile section of Cleveland street with open ditches experienced drainage problems during heavy rainfalls. The design called for widening and reconstruction of the street and the addition of a curb and gutter, storm drains, sidewalks, and retaining walls. The design was complicated by several factors. The vertical grades in this area are in excess of 13%, necessitating curved vane grates to catch quickly moving stormwater. A new box culvert was installed along with block retaining walls and articulated matting to protect the outlet channel from erosion. A large concrete retaining wall was constructed to retain a parking lot embankment and improve sight distance at the Leverett Avenue intersection.
