The Little Beaver Creek Improvements project includes regrading the east and west creek banks along approximately 1300 linear feet of Little Beaver Creek adjacent to Lion's Park. In addition to the bank regrading, a limestone outcropping stair step will be constructed south of the pedestrian bridge, on the west side of the creek. These steps will include limestone blocks, gravel subbase and permeable membrane, along with riprap stone around the stairs. Additionally, the project will regrade an existing berm on the west side of the creek and remove approximately 10,300 CY of soil. A portion of the soil will be used as fill within Lion's Park, which will be spread and mass graded. Existing utilities will be adjusted as needed in the vicinity impacted by the grade changes. The improvements include excavation of approximately 13,338 CY of total earthwork, 6 minor and major adjustments to sanitary manhole structures, removal of approximately 700 SY of PCC sidewalk, removal of approximately 33 trees (truck diameter greater than or equal to 3"), removal of various park amenities (gazebo, shed structure, and chain link fences/backstops) temporary and permanent seeding, traffic control, erosion control, and miscellaneous associated work necessary to complete the project.
