Minimum maintenance standards for public and private storm and surface water systems including LID, rain gardens, stormwater planters, porous pavement and green roofs.
(2010) City of Bellevue Utilities Department. Minimum maintenance standards of public and private storm and surface water systems. Low Impact Development stormwater management maintenance is also covered, including rain gardens and stormwater planters, porous pavement and green roofs.
These Maintenance Standards set forth the minimum standards for the maintenance of public and private storm and surface water systems. These facility specific maintenance standards are intended to be conditions for determining if maintenance actions are required as identified through inspection. They are not intended to be measures of the facility’s required condition at all times between inspections. In other words, exceedance of these conditions at any time between inspections and/or maintenance does not automatically constitute a violation of these standards. However, based upon inspection observations, the inspection and maintenance schedules shall be adjusted to minimize the length of time that a facility is in a condition that requires a maintenance action.
