This project consists of constructing curb spillways and a bio-swale to intercept parking lot runoff before discharging to the Rouge River. The work also includes erosion repairs on the vegetated slope from the parking lot to the river, construction of a riprap-armored spillway down the slope, and restoration of the adjoining slope and embankment in Birmingham, Michigan. Approximate quantities include 70 square yards of natural stone riprap, 20 foot long ledge rock level spreader, 250 square yards of Turf Reinforcement Mat, 550 square yards of Erosion Control Blanket, and associated clearing, grading, and native seed mixes and fertilizer, plus other work to make a complete project. Bid alternates are also being requested for installation of 245 feet of 6-ft tall decorative aluminum fencing, and native bio-swale plantings (shrubs, perennials and grasses).
