Continuing Education Credit Information
This webinar is open to the public and offers 7.0 PDHs to professional engineers and 7.0 HSW continuing education hours to licensed landscape architects in all states.
HalfMoon Education is an approved continuing education sponsor for engineers in Florida (Provider No. 0004647), Indiana (License No. CE21700059), Maryland, New Jersey (Approval No. 24GP00000700) and North Carolina (S-0130). HalfMoon Education is deemed an approved continuing education sponsor for New York engineers and landscape architects via its registration with the Landscape Architecture Continuing Education System (Regulations of the Commissioner §79-1.5(i)(2) and §69.6(i)(2)). Other states do not preapprove continuing education providers or courses.
The Landscape Architecture Continuing Education System has approved this course for 7.0 HSW PDHs. Only full participation is reportable to the LA CES.
This webinar has been approved by the Association of State Floodplain Managers for 7.0 CECs for floodplain managers.
This course offers 7.0 PDHs/continuing education hours to most licensed/registered geologists. HalfMoon Education has not applied for state geologist continuing education approval in states requiring such.
