A Financial Impact Assessment Of Ld 1725: Stream Crossings, New England Environmental Finance Center, Muskie School Of Public Service

Water

This report looks at the potential financial impact of LD 1725 on the estimated 30,000 stream crossings in the State of Maine that would be affected by the law. Our research for this report included the analysis of nearly 2000 stream crossings and the data collection necessary for the development of extensive stream crossing replacement cost models. We found that the 1.2 bankfull requirements in LD 1725 would result in a 75% ‐ 250% increase in structure widths for stream crossing projects across the state. An upsize of this magnitude would increase the cost of replacing stream crossings statewide by …

Culvert Material Cost Comparison, New England Environmental Finance Center

Economics and Finance

The following tables provide a detailed look at the role that culvert material and culvert diameter play in the overall cost of a culvert replacement project. Table 1 displays the cost per foot purchase price arranged by diameter size for the various culvert materials that are currently available. Table 2 displays the average additional culvert pipe material cost (increased cost to upsize minus original in-kind replacement cost) that would be incurred when upsizing a given diameter of culvert with a 50 foot length by factors of: 200%, 250% and 300%.

Construction Cost Models, Barry Dikeman

Economics and Finance

The following are a series of cost estimate models similar in format to a typical engineer’s estimate that were developed in support of our financial impact assessment report for LD 1725. The models us current material costs, labor costs, and equipment costs for the region to provide a comparative cost analysis of seven culvert replacement scenarios. The models provide information about what the cost impact of LD 1725 would be for typical culvert replacements in Maine. However, due to the inherent restrictions of the cost modeling framework we were not able to include the abundance of variables that would be …

Sustainable Portland: Implementation Series 3, New England Environmental Finance Center

Climate Change

This report is the third in a series of efforts by students at the Muskie School of Public Service, Community Planning and Development Master’s program, in a core class called “Sustainable Communities.” In this course students seek to understand principles of sustainability and how efforts to implement Sustainability programs can become more successful. The report assembles term papers students completed on particular efforts by municipalities, universities, and other groups to achieve sustainability goals. Students worked on each project in a service learning format with real world clients. They were asked to fashion their papers around lessons learned by other organizations …

Land Conservation And Land Use In New England: Trends, Challenges & Opportunities, Amanda Loomis, Tom Devine, Andrea Small, Brittany Howard, Brett Richardson, Stephanie Dulac

Land Conservation

Sprawling development patterns accelerated across the New England landscape in the last three decades and consumed the region‘s forests, farms, and open spaces at an unprecedented rate. New England‘ers in all six states formed land trusts, supported statewide conservation organizations, and collaborated with state and federal partners to protect some of their most-prized recreation lands, wildlife habitats, and working lands. The current economic recession has slowed development pressures across the region and offers an opportunity to build on recent successes. The time is right to plan a coordinated New England conservation strategy that protects and links the region‘s natural assets. …

Sustainable Portland: Implementation Series 2, New England Environmental Finance Center

Climate Change

The Portland Municipal Climate Change Working Group prepared a report in March 2008 that outlined several recommendations as a commitment by the City to address greenhouse gas emissions (GHG) produced during daily municipal operations. The Municipal Climate Action Plan was written in partnership with Clean Air – Cool Planet and Portland officials, and acknowledges under Recommendation #2 that an employee energy efficiency program would provide significant positive impact on the City’s reduction of greenhouse gas emissions. Best practices from three cities show that focus on the greening of City Hall is critical in developing a program that promotes partnerships, community …

Brunswick Me: De-Militarizing The Bnas, Anne Holland, Brett Richardson, Richard Barringer

Planning

Closure of the Brunswick Naval Air Station in 2011 will have profound economic impacts on the entire mid-coast Maine region of Maine, with an estimated loss of 6,500 jobs and $330 million annual income. Throughout the Base Realignment and Closure process, Brunswick, the region, and the State of Maine followed federal rules and developed the federally-funded Brunswick Local Redevelopment Authority (BLRA) to plan for reuse of the 3300 acre base. In its planning process, the BLRA adhered to a number of well thought-out Guiding Principles, including the use of extensive public participation and the consideration of “smart growth” principles and …

Sustainable Portland: Implementation Series 1, New England Environmental Finance Center

When the Sustainable Portland Task Force Report was released in November 2007, under the leadership of Mayor Jim Cohen, Portland Councilor Kevin Donoghue had the idea that students at the Muskie School of Public Service might be able to help implement recommendations from the report. It may have helped that Kevin was himself a graduate of the Community Planning and Development Master’s program at the Muskie School, but it was a good idea nevertheless. He approached Professor Sam Merrill in the CPD program, who spoke with the new Mayor Ed Suslovic about a possible partnership between the City and the …

Mansfield Ct: Planning A New Village Center, Maggie Jones, Richard Barringer

Planning

The case follows the development of a plan for a new village center in Storrs, the central village of Mansfield, Connecticut. A process that was transparent and inclusive of the community members yielded a plan that gained the approval of the Town, the landowner (the University of Connecticut), and the citizenry. The process relied on the mending of fences, the leadership of key participants, and an innovative strategy that included development of a nonprofit corporation and creative use of grant money. While zoning changes are still in the works, the first stage of building goes forward.

Augusta Me: The New Bridge Begets A New Planned Neighborhood, Molly Pulsifer, Richard Barringer

Planning

Construction of a new Third Bridge over the Kennebec River in Augusta offered the prospect of a new and handsome gateway to the city. Further, the resulting change in traffic patterns offered the City the chance to plan for a pattern of development quite different from what the city had experienced for the past half-century. The case study describes the planning and construction of the new bridge and corridors that re-routed traffic out of Augusta’s downtown and older neighborhoods, and created the opportunity for planned development adjacent to the corridor created by the new bridge. It goes on to describe …

Analysis Of Per Capita Expenditures Of Suburbanizing Communities In Maine, New England Environmental Finance Center

Economics and Finance

This study analyzes per capita expenditure trends among selected fast-growing Maine towns from 1970-2004. The ten communities studied are termed as “suburbanizing” towns. This term is used to describe towns that over the past 30-40 years have been in the process of transition from rural to suburban – in terms of their population and housing densities, their forms of government, and the services they provide, as well as other characteristics.1 Such towns are of particular interest because they have been absorbing a healthy percentage of the state’s population growth during this time period, often at the expense of Maine’s service …

Land For Maine's Future Program: Increasing The Return On A Sound Public Investment, Richard Barringer, Hugh Coxe, Jack Kartez, Catherine Reilly, Jonathan Rubin

Economics and Finance

Maine is nowhere a more special place than in the quality of its landscape and the traditions of its land use. Among the mo st privately-owned of all the states, Maine’s natural diversity and beauty combine with its traditions of resource stewardship, open access, and appreciation of nature to distinguish it in the public mind and national imagination. In recent decades, however, these traditions have come under assault from the forces of economic and social change; and the people of Maine have responded. In 1986, Governor Joseph Brennan’s Special Commission on Outdoor Recreation recognized the growing threats to Maine’s natur …

Model State Land Use Legislation For New England, New England Environmental Finance Center, Muskie School Of Public Service

Legislation

Sprawl is neither the ordained nor the inevitable outcome upon the New England landscape. A coordinated response to sprawl by the public and private sectors is possible, and could dramatically improve land use patterns and reduce the cost of local government. For the New England states, such a response would include, among other elements, legislation to eliminate existing gaps in the land use laws of each state – gaps that presently encourage or sanction sprawling development. It would also include incentives for municipalities to think beyond their borders and to act with greater efficiency and effect. It is the purpose …

Guiding Growth: A Survey Of Tax Incentives, New England Environmental Finance Center, Muskie School Of Public Service

Legislation

Current development patterns and increased tax pressures in local municipalities combine to harm both Maine’s natural resources and its quality of life. Previous initiatives such as the implementation of zoning laws did not fully result in the desired outcomes. Zoning laws were often too flexible and often did not resist market and political pressures to change zoning regulations to allow development with possible economic growth. A sound taxation system or fee structure may be the solution to slow down development in natural areas and direct it towards areas appropriate for growth.

To protect Maine’s natural resources more successfully from future …

Smart Growth And Land Acquisition Priorities, New England Environmental Finance Center

Land Conservation

It is well-known and generally accepted that all undeveloped land in New England cannot forever be protected from development; nor would this be a desirable goal, as continued economic development and population growth are near certainties. For these and other reasons, private land trusts and government agencies generally use explicit criteria to prioritize their land acquisition activities and prospects.

Much land protection in New England and elsewhere, however, has occurred without substantial attention to such land use needs as fostering the best locations for where people will live, businesses will locate, and infrastructure will be built to avoid degrading resources. …
