Tidal Flooding Mitigation Project - RBA Response to "backfill" Inquiry

Last month, one of our neighbors contacted us with the below question regarding "backfill" of the breezeway of their property. 
"I understand that there will be "limited" backfill provided by the city to address the bowling effect on the properties but I am wondering exactly where the cut off point will be so that I can plan accordingly. I was planning on taking down my front deck as well as the breezeway decking and eventually cement the area."





 
We passed this inquiry along to the city's design firm and earlier today we received the following reply from Mr. Joseph Menza of the RBA Group.

Sorry It has takensome time to get back to you.  One of the major milestones in a capital project for DDC is Mass Mailing no. 1 / Alignment Meeting.  This is the point where we have developed set of preliminary plans that are distributed to many of the city agencies and utility companies.  This happened last week,so that is why I am first getting back to you now, as we were really just focused on that milestone.

With regard to your question, there is no simple answer.  The design varies based on the grade difference, if the breezeway is used as a driveway, existing walls/decks are present, etc.  We are looking at each individual property one at a time. However we are trying to use some standard guidelines.  In many areas weare proposing to grade back to a point where the proposed grade isapproximately 1’ higher than the existing grade.  At this point we will install a concrete header (6” wide x 2’ deep concrete curb) and two concrete steps to step down from the higher grade to the lower grade.  I must stress this is one example and that different scenarios require different solutions, so please understand we are looking at every property individually for the best solution.

At this point many things are still subject to change pending both the comments we get from thecity agencies and utility companies and when we meet with community next to go over our proposed plan one more time.

 As always, we will keep you advised of all new information regarding this project via postings on this site.
