    West Environmental, Inc. (WEI) conducted a city-wide Vernal Pool Inventory to locate, document and map vernal pools in Portsmouth. This effort was coordinated with the Portsmouth Planning Department and Conservation Commission to help the City of Portsmouth in vernal pool identification and mapping. The goal of this project was to locate isolated wetlands that provide vernal pool habitat. Currently the City of Portsmouth’s wetland regulations exempt wetlands less than 5,000 square feet from the local 100’ buffer zone. This study identified smaller wetlands which have the potential to provide vernal pool habitat that may deserve the 100 foot buffer protection. It should be noted that vernal pool habitat can exist in a variety of freshwater wetlands including larger red maple swamps. These areas were also mapped when encountered. A field workshop was held for the Conservation Commission members to give them hands-on training in vernal pool ecology. The results of this Vernal Pool Inventory were presented to the Portsmouth Conservation Commission in July of 2008. Based on the results of this study and the recent revisions to the NHDES Wetlands Bureau regulations which added rules for vernal pool protection, the Portsmouth Conservation Commission has recommended a change to the Article 8 - Environmental Protection Standards of the City of Portsmouth to include vernal pool identification and protection with a 100’ buffer

    Impervious Surface Analysis for Durham Under Current and Build-Out Conditions In Support of Stormwater Management

    Get PDF
    An analysis was performed to determine current and projected impervious surface areas in the Town of Durham, New Hampshire with the purpose of generating data to guide the adoption of stormwater management practices in the Town. Because impervious surfaces affect stormwater runoff peak flows and volumes significantly, it is critical to understand the Town’s impervious area characteristics (and the resulting stormwater management implications) under current conditions in order to develop appropriate stormwater management policies

    Purpose. This research is focused on identification of illegal dumps in the territory of Dubna, their geometrical sizes, composition, sources of education; assessment of ecological danger of dumps and analysis of dynamics of a situation over the last ten years: 2004-2014.Design/methodology/approach. Researches were carried out by means of field, calculation, statistical and cartographical methods. Findings. Hundred illegal dumps are founded in the territory of Dubna in 2014, over the last 10 years the amount of dumps has reduced much in a residential zone of Dubna, the situation has improved not so significant in recreational zones. Eighty percent of dumps are characterized as dangerous since they are located in relief depressions, in residential and “green” zones of the city, near reservoirs; they contain dangerous components in their own composition. Plastic, glass and wood waste have the greatest volumes in damps. Vacationers in “green” zones of the city and inhabitants of the private sectors are the main pollutants. The lack of containers for collecting waste in places of a recreation and around some garden associations is revealed. All obtained data are presented in the complex GIS-project that gives ample opportunities of processing and the analysis of data.Practical implications. All obtained and processed data are communicated to the company responsible for the waste management in the city of Dubna (JSC “RFK Ekosistem”), the part of dumps is liquidated, container network and routes of export of waste are perfected
