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

Outcomes

Describe and quantify progress towards achieving the conservation activities described in your original

proposal. (Quantify using the approved metrics referenced in your grant agreement or by using more relevant

metrics not included in the application.) Outcomes are defined as the longer-term or “big picture”

environmental result(s) that you expect will ultimately occur as a result of a particular activity or activities.

For projects with continuing long-term benefits (such as riparian buffer plantings) you may want to estimate

the environmental benefits after a set period of time (say, five years). For studies you should describe the

usefulness of the data to applied resource management or it role in developing new tools or techniques for

applied resource management.

Briefly explain differences between what actually occurred compared to what was projected to occur.

Provide any further information (such as unexpected outcomes) important for understanding project activities

and outcome results.

Goal: Reduce nonpoint source pollution and shoreline erosion due to stormwater runoff by implementing

BMPs including catch basins, infiltration basins, and bioswales to increase detention, filtration, and

infiltration of road runoff.

o Proposal Metric: surface water sampling

o Water quality data for the project vicinity was compiled as a pre-construction baseline reference.

Surface water data collected prior to the first growing season (2014) can be used in the future to

assess whether there has been a measurable improvement in water quality within the project area.

The selected data parameters are associated with stormwater runoff sources (e.g. nitrogen,

phosphorus, fecal coliform). This project was implemented to improve water quality by reducing

concentrations of these parameters from entering Conscience Bay by installing catch basins,

infiltration basins and bioswales in the adjacent buffer areas. By comparing parameter

concentrations over time, inferences may be made regarding project success, as well as, other

possible contributing factors related to changes in overall habitat health.

There was no direct field collection in this phase of the project. Secondary sources of data were

accessed and reviewed, including NYSDEC Bureau of Marine Resources Shellfish Unit and Long

Island Water Sentinels. These two data sources were evaluated and selected during the project

planning phase (2012) based upon the availability of water quality data within the project area

and type of data collected. The collection and review of existing baseline data of quality allows

for a more accurate depiction of trends and correlations related to the progression of project

establishment in years ahead. Data collected was summarized in the post-construction

monitoring report. Additional data collection would be required following the completion of this

Page 5 of 255

construction phase grant project for comparison analysis. It is anticipated that NYSDEC will

continue sampling in support of their Shellfish Growing Area Classification Unit.

o Difference(s) between projected and actual occurrence – The original LI Sentinel volunteers local

to the project area were not able to assist with the proposed sampling. New volunteers were

trained in February and assisted with intermittent sampling during the 2013 growing season. Due

to scheduling conflicts and expired sampling equipment (e.g. test strips), sampling events were

discontinued in the fall of 2013. Data collection may resume in the future depending on funding

and volunteer availability.

o Long-term benefits (2018) – Project installations for stormwater treatment along Old Field Road

will result in reduced runoff volume and improved runoff water quality entering the Conscience

Bay ecosystem. By raising the road surface elevation, drainage patterns will be directed toward

stormwater treatment structures. The catch basins will remove sediment (total suspended solids)

and floatables pollution. The leaching pools and infiltration basins will reduce the stormwater

volume and resultant wetland erosion. The bioswales will additionally reduce the stormwater

volume as well as remove suspended solids, nutrients, and metals. This project will assist in the

recovery of a healthy and functional aquatic habitat, which is currently considered an “impaired

waterbody” by NYSDEC. Improved water quality will lead to a re-evaluation of shellfish

harvesting designations by NYSDEC.

Goal: Enhance the quality of Conscience Bay’s upland buffer and wetland habitat and reduce nutrient loading

through the removal of invasive plants and installation of highly-valued native plantings.

o New Project Metric: plant survivorship and wildlife use

o During project construction approximately 1 acre of buffer habitat between Conscience Bay and

Old Field Road was enhanced by removal of invasive plants and installation of replacement

native plants. Project planting included 123 shrubs and trees, 12,525 wetland plugs, ~15 lbs.

coastal native seed mix, and transplanting of the State-threatened northern gamma grass

(Trypascum dactyloides). Following the initial installation, a post-construction monitoring event

was completed and findings were summarized in a report for agency review. Overall plant

establishment appeared to be progressing well based on visual observation. Fish and dragonflies

were observed in abundance post-construction. A 2014 spring monitoring event is anticipated,

resulting in project area maintenance by the contractor as needed (e.g. inter-planting, invasive

plant re-sprout removal, site cleanup). To meet project permit conditions 85 percent of target

plants must be established within 5 years.

o Difference(s) between projected and actual occurrence – Due to contractor bid costs, the project

scope was amended to eliminate one bioswale (DZ-3). However, the Village did source additional

funding to complete the installation of the infiltration basins, invasive plant removal and native

plant seeding at this location. Plant substitutions were necessary due to lack of nursery stock

availability (likely related to post-Sandy restoration efforts). Comparable plant substitutions were

approved by the Landscape Architect for similar inundation and salt tolerance requirements.

Construction delays due to severe weather conditions resulted in plant installation later than the

optimal spring planting window.

o Long-term benefits (2018) – The bioswale treatment areas will create a natural buffer habitat

between Old Field Road and existing wetland systems of Conscience Bay. These areas will also

serve as wetland migration corridors in the face of rising sea levels. Implementing the invasive

species management plan will significantly improve the existing buffer community incorporating

NYSDOS recommendations for the improvement of habitat for fish, wildlife species and

enhancement of overall wetland values. Transplanting of the existing northern gamma grass

clusters served to protect the existing population and encourage its expansion within the enhanced

buffer community. The Conscience Bay ecosystem hosts a variety of shellfish, fish and avian

species that will benefit from improved water quality and additional wetland and upland habitat.

Goal: Increase landowner appreciation and public stewardship of Conscience Bay as a coastal resource for the

Village of Old Field community through public participation.

o New Project Metric: public meetings and volunteers/stewards

o The Village engaged residents throughout project construction. In the previous planning and

design phase, public presentations during the monthly Trustees meetings informed residents of

Page 6 of 255

the project need and purpose and involved them in the project decision making process. The

Mayor, Trustees, Village staff, and consultants all took part in educating residents throughout

project construction, responding to questions and concerns as needed. Volunteers assisted with

the wetland planting installation. Following the initial construction, a progress presentation was

delivered at the September Trustees Meeting. Continued communication and engagement of

residents will occur throughout the monitoring and maintenance phase.

o Difference(s) between projected and actual occurrence – Due to scheduling conflicts (i.e. weather

construction delays) the Girl Scouts were not available during the week of plant installation;

however, other local volunteers rallied to spend a day assisting with wetland planting. Also, the

post-construction public walkthrough was substituted with a public meeting presentation due to

safety concerns in gathering along the busy Old Field Road while the project areas were still

sensitive to foot traffic during plant establishment.

o Long-term benefits (2018) – Treating runoff is only part of the solution. The second part is

working with Village residents to reduce pollutant sources. The Village will continue to work to

increase public awareness and understanding of the ecological values and functions of

Conscience Bay. Landowner education on environmentally responsible lawn and garden practices

and pet care incorporated into Village meetings will result in reduced nutrient and pathogen

loading in runoff from Old Field Road. Successful implementation of this project will result in a

model for other locally-based projects within the Conscience Bay, Stony Brook and Port

Jefferson Harbor watersheds. As stated by LISS “many small changes will add up to protect the

Sound”.

3. Lessons Learned

Describe the key lessons learned from this project, such as the least and most effective conservation practices or notable

aspects of the project’s methods, monitoring, or results. How could other conservation organizations adapt their projects

to build upon some of these key lessons about what worked best and what did not?

Inter-municipal coordination and cooperation was critical in gaining project support. Opening lines of

communication within the Village and Town was essential.

The project team confirmed that it is essential to involve regulatory agencies early in the planning and design

phase. Presenting concept plans and organizing a site walkthrough with agency representatives resulted in a more

streamlined approval process of the final design plans.

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 need to be considered 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 within the Conscience Bay Watershed to improve the water quality, enhance wildlife habitat,

and increase the quality of life for Village residents. This multi-faceted approach to water quality improvements

provides grant opportunities that can relieve some of the financial burden on local towns and villages for

implementing these enhancements.

4. Dissemination

Briefly identify any dissemination of lessons learned or other project results to external audiences, such as the public,

governmental agencies, educational entities, scientific, community-based and conservation organizations.

GEI, the Village’s environmental consultant, gave a PowerPoint presentation to the Long Island Sound Study’s

Non-point Source and Watersheds work group on February 13, 2013. The presentation highlighted the early

Page 7 of 255

project accomplishments and planning points for future work. The PowerPoint presentation was posted on the

Village website for public access.

The newspaper article “Stormwater project underway at Conscience Bay” was published by the Times Beacon

Record on July 25th 2013, giving an overview of the project purpose and anticipated achievements.

Due to onsite safety concerns and scheduling logistics, a public presentation was organized following substantial

construction completion. GEI presented the post-construction conditions at the September 10, 2013 Trustee’s

Meeting. Assemblyman Steve Englebright and members from the Three Village Historical Society were in

attendance.

An agency walkthrough with NYSDEC and the Town was scheduled for October 17, 2013. Unfortunately the

Town representatives had last minute conflicts. However, NYSDEC representatives Stephanie Larkin, Tidal

Wetland Biologist, and Sarah Deonarine, LISS Stormwater Coordinator, were able to attend. A second agency

walkthrough occurred on October 30, 2013 with Victoria O’Neil, LISS Habitat Restoration Coordinator.

A Post-construction Monitoring Report was distributed in February 2014 to regulating agencies including

NYSDEC and the Town of Brookhaven.

The Village webpage was updated to share project construction progress through a photograph log.

5. Maintenance and Management

Describe specific provisions for long-term maintenance, management and protection, as appropriate, associated with

project (i.e., maintenance of debris-catching devices, LWD jams, or removing blockages etc.)?

Based on the findings of the spring 2014 monitoring event, the general contractor will inter-plant within bioswale areas,

re-seed adjacent areas, and remove invasive re-sprouts within the entire project area as necessary. It is anticipated that

contractor maintenance of the project areas and removal of goose exclusion and erosion control measures will be

completed in 2014.

The bioswales have been designed to be a low-maintenance treatment measure. The plants selected are all natives that are

associated with shoreline restoration and/or stormwater treatment. An Invasive Species Management Plan has been

prepared for Old Field Road. Implementation of the plan involves removal of invasive plant re-sprouts within the

bioswale areas which will assure the long term functionality of the bioswale areas. The Village will assume the task of

invasive plant management within the project areas. Volunteer stewards may also perform invasive plant removal and

debris cleanup, with prior authorization from the Village.

The Village will perform annual inspections and clean out of all catch basin units. Catch basin maintenance will assure

that the systems are working at full capacity. The infiltration units are designed as no-maintenance structures.

6. Partners:

Describe the contribution of any partnering organization to the project or new partnerships that were developed as a result

of the project?

The Town of Brookhaven partnered with the Village of Old Field in allowing project construction on two (2) of the

Town’s shoreline properties. The Town Board approved a Resolution (No. 2012-107) in support of this project on January

19, 2012.

The Village still anticipates partnering with Girl Scout Troop #91 in future project maintenance efforts, including inter-

planting and invasive plant removal.

7. Project Documents

Post-Construction Monitoring Report Conscience Bay Stormwater Improvement & Wetland Enhancement Project Village of Old Field, New York January 2014

GEI Consultants, Inc., P. C. ii

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
