Case Study: Saving Money Through Alternative Disposal Of Street Sweeping Debris, Town Of Natick, Massachusetts, Edward J. Collins, Jr. Center For Public Management, University Of Massachusetts Boston

Edward J. Collins Center for Public Management Publications

In 2004, Natick submitted a Beneficial Use Determination Application for a restricted use determination by the state Department of Environmental Protection (DEP) for a pilot project to demonstrate that debris collected from sweeping Town roads could be reused to the benefit of the Town. By doing this, the Town would avoid the associated high landfill disposal costs of the sweeping debris, as well as of the cost of disposing excess compost that the Town could now mix with the debris. The majority of the “sweeping debris” is sand the Town uses on its roads during the winter. This pilot tested …

South Burlington, Vt: Mixed-Use Comes To O’Dell Parkway, Ryan Neale, Brett Richardson, Richard Barringer

Planning

The proposed redevelopment of an underutilized property along major travel routes in South Burlington presents possibilities for infill development. The City of South Burlington, the developer, neighbors, and a variety of public and nonprofit financial partners work together to create a mixed-use residential/commercial development to meet a variety of housing and community needs. The case study describes the obstacles overcome to make redevelopment possible through zoning and regulatory changes, negotiation with local residents over traffic and other concerns, support from state and local housing advocates, and political leadership; as well as the development’s application of smart growth principles.

South Burlington Vt: New Urbanist South Village, Jack Kartez, Richard Barringer

Planning

The 220 acre master plan for South Village, the largest project in the City of South Burlington’s history, encompasses multiple housing types and innovative provisions for affordable housing. It integrates housing with open space and natural resource conservation, including a major Community Supported Agriculture project developed by a nonprofit partner, the Intervale Foundation. While not a mixed-use project (that is, commercial as well as residential development), South Village nonetheless represents a qualitative change in approach for South Burlington by incorporating large-scale open space preservation as part of development and multiple housing-types in one project. The case study recounts events leading …

Tailings Tale: Mike Horse Looms Dark Over The Blackfoot, Elizabeth L. Harrison

Graduate Student Portfolios, Professional Papers, and Capstone Projects

In the spring of 1975, a heavy rain blew out an earthen dam holding back toxic metal waste from the now defunct Mike Horse mine at the headwaters of the scenic Big Blackfoot River. Federal agencies, a corporate mining giant, and the small town community of Lincoln, Montana, grapple with the repercussions and future of the watershed.

New Observations Of Gas-Phase Expansion Above A Dense Non-Aqueous Phase Liquid Pool, Kevin G. Mumford, James E. Smith, Sarah E. Dickson

Sarah E Dickson

The partitioning of volatile dense nonaqueous phase liquid (DNAPL) compounds to a discontinuous gas phase results in the repeated expansion, fragmentation, and vertical mobilization of gas clusters. This process has the potential to significantly affect the dissolution of DNAPL source zones and the characterization of DNAPL-contaminated sites, but has not been included in common conceptual models. This study presents new observations of discontinuous gas-phase growth above a 1,1,1-trichloroethane pool in a two-dimensional flow cell packed with 1.1-mm diameter sand. In contrast to the behavior observed in coarse glass beads, these visualization results show that the gas phase evolves as a …

Ecotourism In Dominica: Studying The Potential For Economic Development, Environmental Protection And Cultural Conservation, Vanessa Slinger-Friedman

Faculty Articles

Over the last 20 years, the government of the small Caribbean island nation of Dominica has pursued the development of ecotourism on the island. The hope is that this industry will promote dispersed economic development while providing environmental protection and cultural conservation. However, not enough has been done to determine whether or not the industry is achieving the desired results. To this end, this study explores the growth of the tourism industry on Dominica and shows that, while not perfect, ecotourism is providing some definite benefits to the island in this regard.

Trophic Interactions Associated With Indroduction Of The Invasive Quagga Mussel In Lake Mead, Nevada, Eric Michael Loomis

UNLV Theses, Dissertations, Professional Papers, and Capstones

The ecology of Lake Mead is experiencing an uncertain future since the documented arrival of the invasive quagga mussel. Interactions among constituents of the food web will undoubtedly be altered over time, adversely affecting the popular sport fishery. This study is the first in Lake Mead to present historic trends in lower trophic interactions among threadfin shad and zooplankton before, and shortly after, the arrival of quagga mussels. Shad stomach content analysis revealed cladocerans and copepods were the dominant identifiable food items in Las Vegas Bay and Overton Arm of Lake Mead. Baseline energetics data through the use of stable …

Flowing Toward Sustainability: Two Stream Adjudications Analyzed Under The Iad Framework, Nancye Lou Bethurem

UNLV Theses, Dissertations, Professional Papers, and Capstones

One of the most significant problems impacting the western United States today is the lack of naturally occurring water resources, especially during this period of drought and explosive population growth. This has led to intense competition over water use and ownership in the arid and semi-arid regions of the United States. During this period of water resource scarcity, it is extremely important to determine the ownership of water rights in order to implement optimal management systems. Most western states use a system of "general stream adjudications" to make water rights ownership determinations.

General stream adjudications are legal proceedings used to …

Substrate Monitoring, Contaminant Monitoring, And Educational Outreach On Quagga Mussels (Dreissena Bugensis) In Lake Mead, Nevada, Sara Ann Mueting

UNLV Theses, Dissertations, Professional Papers, and Capstones

The invasive species, the quagga mussel, Dreissena bugensis, was found in Lake Mead, Nevada-Arizona, USA on January 6, 2007. Since then, researchers have been attempting to quantify the amount of damage these mussels will cause to the lower Colorado River basin. Three projects were implemented in this thesis to research the quagga mussel in Lake Mead. First, a study to determine which types of substrates quagga mussels will grow on preferentially was conducted. Six different substrates, Acrylonitrile Butadiene Styrene (ABS) plastic, High Density Polyethylene (HDPE) plastic, Concrete Underlayment Board (CUB), aluminum, stainless steel and fiberglass, were placed in the Boulder …

The plan was prepared under the auspices of the Nantucket Board of Selectmen and guided by the Nantucket and Madaket Harbors Plan Review Committee.

The 2007 plan is an update of the first action plan, which was prepared in 1993, and as such is meant to complement the original plan. The 1993 plan contained extensive background material, much of which is …

Estimating The Effects Of Detection Heterogeneity And Overdispersion On Trends Estimated From Avian Point Counts, Matthew A. Etterson, Gerald J. Niemi, Nicholas P. Danz

United States Environmental Protection Agency: Publications

Point counts are a common method for sampling avian distribution and abundance. Although methods for estimating detection probabilities are available, many analyses use raw counts and do not correct for detectability. We use a removal model of detection within an N-mixture approach to estimate abundance trends corrected for imperfect detection. We compare the corrected trend estimates to those estimated from raw counts for 16 species using 15 years of monitoring data on three national forests in the western Great Lakes, USA. We also tested the effects of overdispersion by modeling both counts and removal mixtures under three statistical distributions: …

The Human Side Of Invasive Species, Ben C. West

Human–Wildlife Interactions

Feral hogs (Sus scrofa) are one of the most visible, troublesome, and interesting invasive species in North America. They have existed in North America probably since 1493 when Christopher Columbus purportedly released some hogs in the West Indies. Since then, hogs have spread across the continent and increased substantially in number. Today, feral hogs are both numerous and widespread throughout North America (Gipson et al. 1998, Adkins and Harveson 2007, Fogarty 2007, Mersinger and Silvy 2007), and published estimates suggested a U.S. population of between 1 and 2 million feral hogs (Mayer and Brisbin 1991).

The Eradication Of Invasive Mammal Species: Can Adaptive Resource Management Fill The Gaps In Our Knowledge?, Sugoto Roy, Graham C. Smith, James C. Russell

Human–Wildlife Interactions

Invasive alien species (IAS) threaten global biodiversity; they are the major cause of species extinction on offshore islands. Management of IAS requires data on the ecology of species in their new environment, how these species respond to management, and how these processes interact. Often, however, there is a paucity of information on key biological parameters that are critical to making management decisions. We sent a questionnaire to professionals and organizations managing invasive species and asked the respondents to prioritize a list of information they required to carry out eradication of invasive species. We analysed responses to assess the level of …
