Upcoming Environmental Education Opportunities

Throughout May and June, Princeton Hydro is participating in a variety of events focused on conserving, restoring, and protecting our precious water resources.

May 7 – May 11: NJWEA 103rd John J. Lagrosa Conference & Exposition

The New Jersey Water Environment Association Conference is the largest water-focused environment exposition in the Northeast drawing participants from throughout the country for four days of workshops, educational sessions, networking events, exhibitor booths and more.

Princeton Hydro Founder Dr. Stephen Souza is giving a presentation on ”Increased Storm Resiliency through the Application of Green Infrastructure BMPs.”

See the conference program.

May 18: Restoration Ecology One-Day Course

This Rutgers Office of Continuing Professional Education course, led by Dr. Stephen Souza, explores the use of mitigation and sustainable design techniques to reduce stormwater impacts and increase storm resiliency.

Designed for those involved in the recovery of impacted river, lake, riparian, wetland and coastal environments, the course will draw heavily upon real-world examples of restoration ecology in practice, and will cover topics, including green infrastructure stormwater techniques; FEMA’s national flood insurance program community rating system (the course is approved for certified Floodplain Manager credits); reconnecting streams to their floodplains; stream daylighting; and more. The course will take place at Duke Farms.

June 4 – 6: Association of State Dam Safety Officials Northeast Regional Conference

The conference program will focus on issues of importance to dam owners, government officials and engineers in the northeast region with applicability to the greater dam and levee safety community as well.  Both general and concurrent technical sessions, timely panel discussions, an informative exhibit show, and networking opportunities with colleagues from across the region highlight this event.

Princeton Hydro is giving two presentations:

June 6: Camden Environmental Summit

The Camden Environmental Summit provides an opportunity for community groups, nonprofit organizations, environmental leaders, and government officials to come together to explore equitable and creative solutions to climate change in the Camden region. Educational breakout sessions include topics like stormwater management, climate resilience, brownfields redevelopment, illegal dumping and improving the overall health of the watershed.

June 8: Sustainable Raritan River Summit

The 10th Annual Sustainable Raritan River Conference and Awards Ceremony is titled “Micro to Macro: The Future of the Raritan.” Conference participants will explore emerging contaminants affecting the Raritan and discuss watershed planning efforts that address threats to achieving a fishable and swimmable status for the Raritan River, basin and bay.

The annual conference typically draws 200+ attendees from state, local and federal government, non-profit organizations, businesses, philanthropic organizations, academia, and individuals committed to a more sustainable Raritan.

The Westtown Dam and Lake Restoration Project is Now Complete!

westtown-0720161456Princeton Hydro is proud to announce the completion of the Westtown dam restoration and dredging project. For the past 10 years, Princeton Hydro has been working with the Westtown School on dam safety compliance and lake restoration and is the engineer-of-record for the restoration of the Westtown dam and lake.

Westtown School, a hallmark of the Westtown Lake community, initially contracted Princeton Hydro to complete dam inspections and assess the lake in terms of its environmental health and the need for dredging. The completion of this project is a testament to the School’s commitment to its mission of “inspiring and preparing its graduates to be stewards and leaders of a better world”. The School leads by example through practicing dam safety compliance and working to restore the lake for future generations.

westtown-img_2438For the dam, Princeton Hydro completed periodic visual inspections, dam breach and inundation analysis, the preparation of an Emergency Action Plan (EAP), and the Operations and Maintenance Manual.

For rehabilitation, Princeton Hydro designed the dam to be able to pass the 100-year flood event via a completely new drop spillway and outfall barrel, and the construction of an auxiliary/emergency cast-in-place stepped spillway. As part of the rehabilitation of the dam, Princeton Hydro surveyed and designed the dredging of 56,000 cubic yards of sediment, the rehabilitation of the lake’s sedimentation forebay and spillway, and the enlargement of a culvert on Westtown Road, immediately downstream of the dam. The culvert replacement was required due to the closure of two secondary outlets on the dam and corresponding culverts below Westtown Road.

westtown-0713161041aThis project also required a variety of permits, including a Chester County soil erosion and sediment control plan approval, a Dam Safety construction permit, a PADEP General Permit 11 for the road crossing, and a US Army Corps of Engineers Individual Permit in compliance with the Federal Clean Water Act.

Additionally, Princeton Hydro successfully navigated interests for two species of concern: the bog turtle (federal and state listed) habitat and red-bellied turtle (state listed) populations.

Following design and permitting, Princeton Hydro provided construction documentation and administration, including the review of shop drawings, monitoring soil compaction, inspecting concrete pours and collecting concrete test cylinders for break tests (ACI certified engineers), completing monthly progress reports, reviewing payment requests and change orders, and attend bi-weekly project meetings with the client. Flyway Excavating, the contractor for the project, worked seamlessly with the School and Princeton Hydro to accomplish the overall goals of the design.

The Westtown project is an excellent example of Princeton Hydro’s turnkey engineering, permitting, and construction administration services. Please contact us if you have a similar project you need assistance with or have questions about.
