Gatz Landscaping completed the initial construction of the project. The following construction elements were implemented: installation of 4 catch basins at 4 drainage sites, installation of 35 Stormtech infiltration units with associated overflow bubblers and rock aprons, removal of invasive plant species, site clearing, grading, and planting to create 4 bioswales. The Village continued to effectively engage residents by sharing project progress at the September Trustees’ Meeting. The project was positively promoted to the surrounding communities through the Times Beacon newspaper article dated July 25, 2013. By the close of 2013, the Village developed a strategy for the 2014 spring monitoring event and subsequent maintenance activities to achieve vegetative success criteria set by NYSDEC. In 2014, the Village anticipates to continue working with NYSDEC, and collaborating with the Town of Brookhaven. In addition, the Village will continue an active public outreach program to inform and engage residents on coastal stewardship activities and ways they can contribute to improving water quality. Lessons Learned • Inter-municipal coordination and cooperation was key to gaining project support. • The project team confirmed that it is essential to involve regulatory agencies early in the planning and design phase. • Selecting a general contractor with similar project experience and positive references who is committed to completing construction tasks accurately and in a timely manner is essential. Inexperienced contractor staff will need additional guidance to ensure construction tasks are completed correctly and efficiently. Effective communication between the contractor, the Village, and their Consultants is critical for successful implementation of a project with multidisciplinary tasks. • Contingency planning and adaptive management are integral concepts that should be considered pre-construction and be implemented as needed during construction. For example, uncontrollable factors such as weather can cause work delays and damage to the project site during construction. As a result, an additional construction crew may be needed to stay on schedule and unexpected tasks, such as watering, may need to be implemented to ensure survival and successful establishment of delayed wetland plantings. • The Village has learned that utilizing innovative means for solving localized flooding and erosion problems can create opportunities

Executive Summary
Conscience Bay is a vital ecological and heritage location on Long Island’s north shore, lying partially within the jurisdictional boundaries of the Village of Old Field. However, over the years the ecological quality of the Bay has been impacted partly due to increased development around the Bay and input from associated stormwater runoff. The Village of Old Field’s Conscience Bay Stormwater Treatment and Wetland Enhancement Project focuses on four major drainage areas along Old Field Road that discharge directly into the Bay. The Village of Old Field was awarded two grants under the 2010 and 2012 Long Island Futures Fund for project planning and design phase and the project construction phase, respectfully. The project scope included the installation of 35 subsurface infiltration units connecting to 4 curbside catch basins, and the creation of 4 bioswales to receive and treat the overflow during severe storm events. This project aims to reduce stormwater velocity and volume through detention and infiltration, and improve water quality through filtration of floatables, sediments, nutrients, metals, and oils. Removal of invasive plants and replacement with coastal natives has provided an improved buffer habitat between the road and Bay, to increase the wetland mitigation corridor.
Final project design was completed by Hayduk Engineering LLC (HE) and GEI Consultants, Inc., P. C. (GEI) in February 2013. All permit approvals were obtained by March 2013. The Construction contract was awarded to Gatz Landscaping Inc. and the initial construction phase commenced in May 2013. Construction activities included site clearing, invasive plant removal, excavation, re-grading, infiltration unit installation with rock lined overflow outlets, wetland plug and shrub planting, seeding, and installation of goose exclusion and sediment control barriers. Delays during the construction phase encountered weather related impacts with near record-breaking rainfall in June and a heat wave in July. The post-construction monitoring event was conducted following completion of the plant installation phase. On August 14, 2013, GEI Ecologists assessed the project areas and observed positive signs of plant establishment overall, noting specific plants that appeared stressed, and saw no evidence of significant erosion or invasive plant re-sprouting. A second monitoring event is planned for spring 2014 to determine plant survival and quantify replacement plant needs, as well as, re-seeding or other site maintenance requirements to be performed by the Contractor.
The Village hosted a public presentation of project status at the September 2013 Trustee’s Meeting, including a resident question and answer (Q&A) session. In October 2013, GEI and HE led a project site walkthrough for New York State Department of Environmental Conservation (NYSDEC) representatives. The Village is planning a follow-up presentation for residents, as well as a walkthrough with the Town of Brookhaven in 2014. Additionally, water quality data collected by NYSDEC and Long Island Water Sentinels was obtained and
