WOW. Your photo says it all!
Recent coastal storms have produced record high water levels. The need for repair of infrastructure may be unprecedented!
I believe state and federal funding may be available in the "disaster relief" category. The following are direct quotes from my recent Google Search:
1. "Individuals can sign up for assistance from the Federal Emergency Management Agency (FEMA). You will need to sign up for assistance at www.disasterassistance.gov (link). FEMA will decide if a grant will be given to you. Grants do not have to be repaid."
2. "Maine | FEMA.gov. Federal Emergency Management Agency (.gov). Check the link below:
https://www.fema.gov › locations › maine
Use this page to find local disaster recovery centers, flood maps, fact sheets, FEMA contacts, jobs and other resources. Maine."
I hope this helps get you started. You are not alone!
