A comprehensive dry flood proofing system to mitigate inland flooding risk for existing or new homes and other buildings. The system leverages the home or building's structure to offer practical and affordable inland area flood protection for structures constructed with a slab on grade foundation. The system includes pluggable weep holes, entry door/garage door/window protectors, wall appurtenances and penetration protection, a house wrap and/or debris barrier for wall protection and sewage anti-backflow protection. The system is reusable, easy to deploy, does not detract from the home or building's permanent appearance, allows for ingress/egress during flood events and can protect the home or building from standing water up to 24″ above slab elevation. The preparation and installation preflood, the deployment immediately preceding a flooding event and the subsequent removal after a flooding event can be provided by both contractors and homeowners.
