shall include facilities and capacity to accommodate the removal of the drywells. H. Service Laterals The street gutter is the primary stormwater collection and conveyance system for individual lot drainage. Lot drainage shall be served by weepholes in the curb where possible. No new bubbler systems shall be allowed. Bubbler systems may be approved, at the discretion of the City Engineer, where weepholes or piped conveyance are unavailable or unfeasible. Stormwater service laterals shall be allowed where drainage from private lots cannot be accommodated by weepholes in the curb. Stormwater laterals are allowed where stormwater conveyance requires a pipe diameter of 8 inches in diameter or greater to convey the flood control design storm. Laterals may be connected to the mainline or existing drainage structures (curb inlets and catch basins) provided the Project Engineer demonstrates conveyance capacity through hydraulic analysis. Manholes are required where stormwater laterals connect to the mainline. A blind connection may be used where the diameter of the mainline is twice the diameter of the lateral or greater. Blind connections shall be perpendicular to the main line. Catch basin or curb inlets may serve as points of connection. Stormwater laterals may be allowed, at the discretion of the City Engineer, for single family dwellings that cannot be served by weepholes. Laterals may be approved where protection of property and drainage of standing water warrants piped conveyance. 2.05 STREETS AND ACCESSWAYS Streets and accessways are required to comply with the City's Design Standards and Guidelines for Eugene Streets, Sidewalks, Bikeways, and Accessways (available in Appendix E and on the internet at www.eugene-or.gov.).
