to hold that embankment up. Nothing has been shown on the plan; nothing has been talked about what will be done there. It would either have to be consolidated in clay or have to be ledged. He doesn't know when that will happen, but it Ali happen. Len said, "Even the sand that's on the abutting property Would plastic sheet pile work?"' Steve said we have a construction protocol put forth by the engineer. AU the best construction practices.are going to be practiced on this project. We know that it's in an area that is highly scrutinized. We're going to be on the site and make sure that all the environmental concerns are net. The engmeer i going to be on site, DPW is going to be on site. There wfll be a constant party watching what is going on. John Slavinsky said that they brought up that issue at the very first geek and the construction protocol was discussed at the last meeting and nothing was mentioned about preventing a cave- in. It was mentioned that 65 cubic yards were going to be excavated, but nothing was mentioned about how the 6 1/2 ft. embankment was going to be kept from caving into the excavation. 1f it caves in, we wih have a real problem them. Steve asked if he is talking from an environmental standpoint or a property_standpoint. Mr. Slavinsky said both. Steve said he doesn't think this is so from the environmental standpoint. He thinks that even if that excavation caved in, with the containment booms that are going to be located on the waterside of the project there won't be any sediment coning through the containment boons. So even if it does cave in and gets into the water, the booms Will catch any sediment on the waterside. mer the construction is done, they will address any embankment concerns as far as caving i or whatever the ease may be. Mr. Slavinsky said we have a property line we have an embankment, vire have W. urtis's property, and we have Riverside Road. If it eaves in, we have a-probl m. Stere asked hove that has any effect from an environmental standpoint. �&. Slavi.nsky said any vegetation. Steve: "Grass?"" Mr. Siavinsky. `Whatever is there, it's different from grass." Steve. "Rosa osa rugosa?" Mar. S avinsky said the work unlit is usually 5 ff. away. Steve said no, work limits are put in place so excavators don't make a mistake and go over it into the resource area and buffer zone. Mr. Slavinsly said that's one reason. The other reason is we usuay have work lints that are a minimum of 5 ft. away. Steve restated that unless Mr. Siavinsky can raise an environmental impact from that walkway, thea there is no met in this forum: As far as this project is concerned, they have covered ah the bases with a construction work protocol. If that happens, it happens. Len asked if the Building Inspector has approved this.project. He asked if there is a structure on an adjacent property, and the work proposed on this property impacts that adjacent structure, that's not a problem for us, it's a problern for some other hoard, right? The Building Inspector said the structure that's on the neighbor's property is ars illegal structure and no permit will be issued. If they meet the setback requirements there will be no problem with that structure because"t will,be well away from the Town property, Mark I urti , 53 N hoi en Road, said he thinks environmentally, it absolutely wih have a future impact. They aregoing to use a type of hydraulic machine, and he doesn't care what kind of .
