The objective of this paper was to examine the profit levels, energy use and environmental impacts of two residential development scenarios in a watershed in the Philadelphia region under two zoning assumptions. The two scenarios were based on economic suitability and environmental suitability. A key question was whether these occurred together in...

These projections appear in Table 2, with those municipalities (Lower Moreland and Philadelphia) with negative or zero projected growth omitted. ...

(1) The territory mapping technique is a standard method in bird census work, usually involving eight to ten surveys of the study plot in the breeding season. The population estimate is based on the number of clusters of `registrations' (point-records), each acceptable cluster containing at least a standard minimum number of registrations. Difficul...

The Wissahickon Creek Watershed is one of five major watersheds in the Philadelphia metro region. The main objective of the work in this paper was to determine and compare the energy and environmental impacts of placing housing in the Watershed according to profitability and environmental sustainability criteria, respectively, in the context of increasing urbanization. Future population and employment for the Watershed have been projected by the Delaware Valley Regional Planning Commission. Housing requirements for the projected populations in each municipality were computed, and their location was influenced by the local zoning ordinances. Suitability analysis using ArcGIS 10.6 generated areas for development based alternatively on profitability and local sustainability. CommunityViz 5.2 Scenario 360 software was used to place buildings within the appropriately-zoned areas. Using Argonne National Laboratory’s Greenhouse Gases, Regulated Emissions, and Energy Use in Transportation (GREET1 2018) software and water quality monitoring information from the Philadelphia Water Department, impacts were directly estimated. The impacts were related to effects on ecosystem functioning, ecosystem goods and services, and broad value estimated for the latter. The effects were used to indicate what might be appropriate policies to reduce the negative environmental consequences of residential development in the watershed. Unexpectedly, the environmental impacts of the profitable and sustainable scenarios were not very different. This suggests that profitability and sustainability need not be mutually exclusive.
... Because SS and EC are two parameters involved in WQI 5 determination, they need to be evaluated carefully. Thus, SS and EC estimation methods could be embedded in the model to effectively estimate WQI 5 values under extreme storm conditions (Gilboa et al., 2014;Sorrentino et al., 2014;Wong and Hu, 2014). In this study, WQI 5 was included in WASP to obtain WQI 5 values according to the simulated data after water quality simulation using the WASP model (Ashton et al., 2014;Dai et al., 2014). ...

The goal of this study was to establish a modeling tool for river water quality with a direct linkage to the water quality index (WQI5) calculation and the river water quality model, the Water Quality Analysis Simulation Program (WASP), for pollutant transport modeling. The integrated WASP and WQI5 tool was field-tested to assess pollutant loadings and their impacts on river environment. Suspended solid (SS) and electric conductivity (EC) correlation equations and the WQI5 calculation tool were included in the water quality model and direct WQI5 calculation. The SS concentration, which was influenced by river flows, had crucial effects on river water quality and WQI5 values. EC value was controlled by dissolution of soil minerals, which was affected by the watershed drainage area and surface runoff. The integrated system could establish a direct correlation for river water quality, river flow, and WQI5.
... Alonso applied this model in a monocentric city and found that households choose their residential location by maximizing a utility function depending on their goods expenditures, land lot size, and distance to the city center [12]. Studies afterward described residential location choice by introducing the discrete modeling framework [13,14]. This framework quantifies the impact of different residential location characteristics and their interactions with household characteristics. ...

Thesis
Conventional drainage systems are increasingly struggling to manage twenty-first-century demands, including urbanisation and climate change contributing to combined sewer overflows (CSOs). In some cities, Green Infrastructure (GI), including SuDS (Sustainable Urban Drainage Systems) and WSUD (Water Sensitive Urban Design), is now being encouraged and used. Adopting sustainable drainage systems which, capture, slow and manage stormwater at ground level, before discharging it to receiving watercourses, by mimicking nature, will help to alleviate the struggling conventional sewer systems. The research aimed to establish the role of GI, including SuDS, as twenty-first- century solutions to the issues that conventional sewer networks face. For this study, qualitative approaches enabled the researcher to collect and collate data from literature and establish the beliefs of industry experts on GI stormwater/surface water management approaches. An in-depth literature review and several semi-formal interviews, allowed the researcher to construct four cases, which analysed vital areas concerning the cost, maintenance and performance of GI systems, on the four varied stormwater management projects. The results demonstrated that GI is being implemented across the world. Philadelphia, US has embarked on the most extensive GI programme in the US, whereas over £4bn is being spent on the Thames Tideway Tunnel in London, UK, to alleviate combined sewer overflows (CSOs). The researcher confirmed that GI is a practical and effective stormwater management approach and that ‘issues’ including maintenance can be solved if more positive and progressive approaches are taken from the offset of projects. For example, in the planning and feasibility phases. Several recommendations are made, including promoting a multi-stakeholder approach and for improved clarity over the maintenance responsibilities of SuDS through legislation and guidance.
