*'''Lack of planning and communication.''' Poor communication protocols and the pace and extent of construction may preclude proper inspections and certifications.

Regular inspections throughout the construction process of LID practices prevent end products that are not built to the design specifications. Specifically, they ensure that:
*the LID practice has a proper layout, location, footprint, and volume;
*materials meet design specifications;
*the contributing drainage area is stabilized before the LID practice becomes operational;
*environmentally sensitive areas and the LID practices themselves are protected during construction; and
*inlet, outlet, pretreatment, and piped elements have the correct elevations and inverts.
Furthermore, keeping records of these inspections helps to certify the works after construction and makes for a smooth assumption process.
