WATER PONDING ON LANDSCAPING
The site shall be graded to shed water in accordance to the requirements of the design. Where no grade is specified in the design for a slope, a minimum gradient of 2% is considered acceptable; sod or graveled areas may have a minimum gradient of 1%.
One -Year – Work and Materials
Site grading shall meet the acceptable condition by conforming to a municipally approved grading plan/site plan, where applicable.
Typically municipalities require ponding in landscaped areas to dissipate within 48 to 72 hours after a water event (please also see REFERENCE final item number related to ponding on walkways and driveways) After the first year, the owner is responsible for maintaining the finished site grading to ensure ponding water does not adversely affect their premises.
