This is a set of construction drawings for a layout and grading project, dated August 2, 2024, with job number 24.081 prepared by engineer Rivard. The drawings depict site plans showing existing and proposed infrastructure improvements at a facility location with multiple sheets detailing north, south, and construction views.

The project includes proposed concrete pavement construction (6-inch and 12-inch non-reinforced), concrete curb and gutter, concrete valley gutters (8-inch), and drainage infrastructure consisting of three proposed 36-inch catch basins with covers, approximately 61 feet of 12-inch reinforced concrete pipe (RCP), 105 feet of additional 12-inch RCP, 49 feet of 12-inch RCP, 150 feet of 8-inch PVC piping with openings through pavement to connect existing building downspouts, and a culvert outlet with 61 feet of 12-inch RCP. The work also encompasses gravel placement, aggregate base course for positive drainage, subbase preparation or removal based on existing material conditions, placement of geotextile fabric and riprap (plain riprap not to exceed 450 square yards and heavy riprap not to exceed 300 square yards), restoration of washed-out areas with wildlife-friendly mulch blanket, topsoil, fertilizer, and seed. The contractor must provide a joint layout for concrete pavement to the owner for review 14 days prior to concrete placement. Existing structures including buildings, tanks, utilities, fencing, lighting, bollards, and manhole infrastructure are to remain in place throughout construction.
