Annual Report 2018

CBEP has been collaborating for over 25 years with a multitude of partners working hard to protect Casco Bay. 2018 brought us new and exciting collaborations. The Casco Bay Nutrient Council, convened by CBEP, met for almost two years and produced a report that laid a path forward for all partners to tackle nutrient pollution. CBEP worked closely with the EPA to establish the Casco Bay Monitoring Network, made up of over 20 member organizations, aimed at coordinating and upgrading monitoring in the Bay. The Network is currently updating the Casco Bay Monitoring Plan. CBEP is an active participant in the City of Portland’s new Integrated Plan for Water Resources. The end goal of the “Blue Portland” Integrated Planning Process is to analyze and refocus policies and funding toward more beneficial investments in stormwater, wastewater, and combined sewer overflows (CSO) abatement. A new coalition in the Sebago watershed is focused on conserving upstream forests to protect Sebago water quality. And a burgeoning New England coalition is experimenting with using natural materials to reduce shoreline erosion and improve coastal habitat. CBEP is a partner in both collaborations. Collaboration has always been a central mission for CBEP

Casco Bay Plan 2006 Update

The Casco Bay Estuary Partnership (CBEP, formerly the Casco Bay Estuary Project) is a collaborative effort to preserve and protect the bay’s resources. The partners include local, state, and federal agencies and interested citizen groups. In 1990, the U.S. Environmental Protection Agency designated Casco Bay as “an estuary of national significance,” leading to the formation of the CBEP. For the past 15 years, CBEP has received significant annual federal funding to develop and implement a plan for the bay’s future

Guidance for Private Property Owners: Steps and Alternatives for Disposal of Material Dredged from River and Harbors of Casco Bay

The overall goal of the project is to help private owners navigate the dredging/disposal process and make informed decisions that are: Cost effective (including all steps of the process); In compliance with regulations; and Geared to specific needs (material volume, sediment type and level of contamination). As part of this objective, we have attempted to do the following: Describe the regulatory process for disposal alternatives (upland, ocean, and others) in simple but accurate terms. Develop a complete list of disposal alternatives. Develop a comprehensive alternatives analysis for possible disposal alternatives and screening process. Develop a resource compendium in an appendix, including resources (websites, reports, contacts, used to develop information)

Casco Bay Watershed Fish Barrier Priorities Atlas: Phippsburg

This atlas was created to help guide restoration of streams affected by road-stream crossings and dams acting as barriers to fish passage in the Casco Bay watershed as part of a project coordinated by the Casco Bay Estuary Partnership (CBEP) and U.S. Fish and Wildlife Service Gulf of Maine Coastal Program (USFWS-GOMCP). The 42 individual town maps of the atlas contain crossings, dams and a small number of natural barriers identified during field surveys of perennial streams in 2009 and 2010, and mapped using a geographic information system (GIS). Sites have been classified by the degree of restriction they represent for fish passage, and additional related data such as high priority stream habitat and flood hazards are shown in the maps to help identify priority sites. Data have been compiled into a database for use in analysis and mapping

Simulating discontinuities in a gradient-enhanced continuum

A continuum-discrete model for failure in quasi-brittle materials is presented. The continuum is regularised through the introduction of gradient terms into the constitutive model. At the transition to discrete failure, the problem fields are enhanced through the use of a discontinuous interpolation. The continuum model is able to simulate micro-cracking, while a traction-free discontinuity represents the macro crack. The discretisation procedure is described in detail
