====LID construction notes====
LID design drawings need detailed construction notes within the design drawings. These notes should include details relevant to:
*sequencing and staging areas
*material specifications
*testing requirements
*installation procedures
*elevations and invert details for inlet, outlet, and overflow features
*grading details for conveyance features
*erosion and sediment control requirements
*inspection and maintenance responsibilities during construction and prior to assumption
The last two bullets require further comment. LID facilities are most vulnerable to sedimentation and clogging during their own construction and construction of adjacent and connected lands. LID construction contracts should specify a sufficient combination of ESC measures and inspection and maintenance of the LID facility during the construction and assumption phases to ensure that it will function without remediation. Contracts for larger-scale projects, e.g., where the LID facility in question is part of a road reconstruction project or subdivision development, should contain clear terms covering responsibilities for keeping sediment from entering newly constructed LID features and removing it if necessary.
