The Official Location of the Application Form: US Army Corps of Engineers Operation Blue Roof Applications Form Sept. 2021 Hurricane Ida.
If you have called the US Army Corps of Engineers as instructed by FEMA following the FEMA information link ( https://www.fema.gov/disaster/hurricane-ida#rebuild ) You most likely found the following information.
Clean-Up, Repair and Rebuild
Operation Blue Roof
In Louisiana, the U.S. Army Corps of Engineers (USACE) has activated its Operation Blue Roof program for parishes approved for individual assistance. Residents can sign up for the program and complete a Right of Entry form at BlueRoof.us.
Call toll free 1-888-ROOF-BLU (1-888-766-3258) for more information.
If you called using the Roof-Blu 888 number you were instructed to click on the "BlueRoof.us" link that would have redirected you to https://www.blueroof.us which has a certificate error and a scary screen that advises you to click away. Now, even if you continue you are then redirected to a different page over at the US Army Corps of Engineers main website and you start the process of finding the online application link all over again.
Here's the paths you might have taken and at the end I'll share the link to the actual sign up page so you don't have to do all this work.
From BlueRoof.US you are redirected to https://www.mvn.usace.army.mil/ Missions/ Emergency-Operations/ Blue-Roof-Information/ .
On that page you'll see an image with a link to the applications page.
That Operation Blue Roof image that shows the word "Apply" then redirects you to https://arcportal-ucop-partners.usace.army.mil/ usaceportal/apps/sites/ #/usace-blue-roof-online-signup
The Operation Blue Roof signup page is the form to allow access to your property and can be accessed by clicking on the Apply Button.
The Apply button then takes you to https://survey123.arcgis.com/ share/ 68358194235145abbf8000ba60386062?portalUrl= https://arcportal-ucop-partners.usace.army.mil/ usaceportal
Now you can use the form to actually apply for your Operation Blue Roof using the official link to the online form.
The US Army Corps of Engineers don't really do well with websites if you ask me. But, once you find the link by then you'll understand how they think.
