Town of Mashpee Conservation Commission <br /> 16 Great Neck Road North <br /> Mashpee, MA 02649 <br /> *NOTE: INDIVIDUAL HEARINGS WILL BE LIMITED TO 15 MINUTES IN LENGTH <br /> (More complex proposals may be granted additional time, if necessary,by the Chair) <br /> NOI 61 & 67 Shoestring Bay Road, 61 Shoestring Bay Road, LLC c/o Glenn Ferguson <br /> & Willowbend Country Club, Inc. Proposed boardwalk. (Representative: Cape & <br /> Islands Engineering, Inc.) (cont. 4.2/4.23 / 5.7) 43- <br /> 3406 <br /> Chuck Rowland of Cape & Islands Engineering stated that the application had previously been continued from <br /> April 2nd, April 23Yd, and May 7th, and that revised plans had been submitted in response to prior Commission <br /> comments. Revisions included additional erosion controls along the coastal bank, proposed two-to-one <br /> mitigation for installed posts, and documentation of abutter approval related to the proposed boardwalk. Mr. <br /> Rowland explained that the proposal consisted of a three-foot-wide elevated boardwalk intended to provide <br /> non-motorized water access, extending from the upland across the salt marsh resource area, with through-flow <br /> decking and vertical separation intended to reduce impacts below. Construction was proposed from shore <br /> access, with limited barge access for the outermost portion of the work. <br /> Commission members raised questions regarding the relationship between this application and a previously <br /> reviewed nearby vista pruning proposal,noting that prior discussion had contemplated overlaying the two plans <br /> to better evaluate cumulative access impacts and the relationship between the separate access proposals. The <br /> applicant stated that it had been his understanding only that this boardwalk would be shown on the vista pruning <br /> plans,but agreed to provide the requested overlay. <br /> Extensive discussion focused on whether the application met the applicable regulatory standard requiring <br /> demonstration that the project would not result in an adverse effect to protected wetland resource areas. <br /> Commissioners discussed performance standards applicable to coastal bank, salt marsh, and land subject to <br /> coastal storm flowage, including whether the current application adequately demonstrated avoidance of short- <br /> term, intermediate-term, and long-term adverse effects. Questions were raised regarding applicability of <br /> Regulation 25 governing land subject to coastal storm flowage, including whether the proposed structure <br /> required a waiver under those provisions. The applicant's engineer argued that water-dependent dock structures <br /> were specifically addressed differently under the regulations and should not be treated as prohibited structures <br /> requiring a waiver. Conservation staff later specifically referenced Regulation 25, Section 7(E), advising that <br /> the provision expressly allowed docks and piers, and therefore indicated that a separate waiver would not be <br /> required under that section. <br /> Commission members raised concerns regarding direct impacts to the salt marsh resource area, including <br /> installation of approximately 32 support posts within the marsh, temporary placement of plywood over marsh <br /> vegetation for construction access, and physical disturbance associated with construction activities. Questions <br /> were raised as to whether temporary mitigation or post-construction restoration would adequately address the <br /> fact that physical disturbance itself may still constitute an adverse effect under the applicable performance <br /> standards. Particular attention was given to the proposed access design, including the inclusion of two ladder <br /> access points. Commissioners questioned whether the interior ladder, combined with tidal conditions at the site, <br /> would result in repeated foot traffic through the salt marsh or adjacent muck areas by users attempting to launch <br /> kayaks or otherwise access navigable water during lower tide conditions. Concern was expressed that such <br /> 4 <br />
