I have overlaid our plan which we did for him in 1996 and have found that since then they have lost upwards of 20’ of property. It is a very small lot and to lose much more would endanger the dwelling. The house is now only 34’ at its closest to the top of bank – which is where we would propose the vertical wall. It would only have about 1.5’ landward exposure and maybe 3’ seaward exposure (proposing sacrificial nourishment above MHW). We have gotten pricing for soft (coir) vs. vinyl sheet pile and they are comparable (roughly $1000 per linear foot just for the wall!) We were told that a rock revetment would be much more expensive than the vinyl sheet pile or coir solutions. Mr. Feola prefers at this time the vinyl sheet pile. A contractor has visited the site and due to the wall collapse and the erosion going on he felt that this should be an emergency filing. I am hoping that since we are staying above “spring high tide” elev., that we can get this approved locally pretty quickly without an emergency filing so he can get someone in there to install it in a timely manner.

They regulations say no but they may mean wet resource areas rather than above extreme MHW. I did speak with the County Coastal Geologist about this property and he had a few suggestions:  As the property is not currently threatened a trigger point could be used based on erosion that would trigger the need for a CES.  A small sloped revetment topped with coir roll or sediment and planted out, rather than a full wall.  The current wall debris could be removed and the property monitored as the erosion rate is not significant  A stone sill could be used to break up wave energy. Thought this might be helpful information Thanks Kelly 1 From: Sarah Ojala - Down Cape Engineering, Inc. \[mailto:sojala@downcape.com\] Sent: Tuesday, February 18, 2020 3:08 PM To: Grant, Kelly <KGrant@yarmouth.ma.us> Subject: question Attention!

It looks like we will be proposing a wall above extreme MHW, with fill behind it with plantings and beach nourishment seaward of the wall to “repair” the beach. We have gotten pricing for a soft solution, vertical vinyl sheet pile and now requesting wood piling/timber wall quote from someone else….is pressure treated allowed (3” stock and pilings above extreme high water)?
