The efficacy of the best management practice (BMP) systems for stormwater treatment has been extensively discussed in respect to water quality. However, little research has been conducted on how form-based variables (e.g., shape, length) can affect the performance of BMP systems. This study presents empirical findings from three common BMP types—detention, retention, and wetland channel—in urban settings of five U.S. states. Total suspended solids (TSS), the number one pollutant carrier in stormwater, is selected for comparison. Multiple years of water quality data are collected from on-site grab samples and from the International Stormwater Database. Geographic Information System (GIS) is used …

3d Digital Graphics In Landscape Architecture Professional Practice: Current Conditions In A Nutshell, Shujuan Li, Bo Yang, Jie Yan
Bo Yang
3D digital graphics and representation have been a critical part in landscape architecture professional practice. However, few studies have been conducted to document how 3D digital graphics are currently being used. Some important questions are largely unknown. For example, who are the primary users of 3D digital graphics programs, and what are the most popular 3D software packages, and why. A better understanding of these questions is not only important to practitioners, but also to educators and software developers. This study tackles the above questions through a national online survey of landscape architecture firms. Five sets of questions were asked, …

Reflections On Developing Landscape Performance Case Studies, Jessica Canfield, Bo Yang
Bo Yang
Increasingly landscape architects are being asked to design and evaluate high-performing, multi-functional landscapes. To grow the profession’s knowledge about landscape performance, in 2010 the Landscape Architecture Foundation (LAF) launched the Landscape Performance Series (LPS). The centerpiece of the LPS are case studies, which aim to illustrate the sustainable features and subsequent benefits of high-performing built works. Though LAF has established guidelines for the content and format of its LPS case studies, a formalized procedure for identifying and quantifying a project’s landscape performance benefits has yet to be developed. As foundation for a forthcoming set of performance benefit guidelines, we reflect …
Green Infrastructure Design For Stormwater Runoff And Water Quality: Empirical Evidence From Large Watershed-Scale Community Developments, Bo Yang, Shujuan Li
Green Infrastructure Design For Stormwater Runoff And Water Quality: Empirical Evidence From Large Watershed-Scale Community Developments, Bo Yang, Shujuan Li
Bo Yang
Green infrastructure (GI) design is advocated as a new paradigm for stormwater management, whereas current knowledge of GI design is mostly based on isolated design strategies used at small-scale sites. This study presents empirical findings from two watershed-scale community projects (89.4 km2 and 55.7 km2) in suburban Houston, Texas. The GI development integrates a suite of on-site, infiltration-based stormwater management designs, and an adjacent community development follows conventional drainage design. Parcel data were used to estimate the site impervious cover area. Observed streamflow and water quality data (i.e., NO3-N, NH3-N, and TP) were correlated with the site imperviousness. Results show …

Cascade Garden Residence Landscape Performance Benefits Assessment, Bo Yang, Pamela Blackmore, Chris Binder
Bo Yang
Cascade Garden is a tranquil, high-altitude residential property, designed to preserve the area's natural setting and ecosystem while meeting the property owner's requests for outdoor amenities. The project involved dismantling an existing house and siting a new home integrated into the landscape with minimal site disturbance. The site features an existing pond, which was planted with riparian vegetation and modified to support trout habitat and supply water for landscape irrigation. Because of the harsh, high-altitude climate and presence of wildlife, plant species were carefully selected to ensure high growth levels and low maintenance. Most of the traditional lawn was replaced …
Riverside Ranch Landscape Performance Benefits Assessment, Bo Yang, Pamela Blackmore, Chris Binder
Riverside Ranch Landscape Performance Benefits Assessment, Bo Yang, Pamela Blackmore, Chris Binder
Bo Yang
Riverside Ranch was one of the first homesteads built in Colorado's Roaring Fork River Valley in the 1880s. The project site was a stop for the railroad and stage coaches travelling to nearby Aspen and a successful agricultural and ranching operation for decades. In the mid-twentieth century, the site transitioned into use as an asphalt mixing plant for the Colorado Department of Transportation. When the landscape architect began work, the site was essentially a brownfield in need of rehabilitation as it was host to multiple rundown historic buildings and remnants of the asphalt plant. The design team reconstructed the landscape …
Capitol Valley Ranch Landscape Performance Benefits Assessment, Bo Yang, Pamela Blackmore, Chris Binder
Capitol Valley Ranch Landscape Performance Benefits Assessment, Bo Yang, Pamela Blackmore, Chris Binder
Bo Yang
Capitol Valley Ranch, a one-acre home site situated on a larger working cattle ranch, is nestled into a rural high-altitude Colorado landscape. The design for the property required an integration of functions. A working ranch with horses, stables, and a barn coexists with a residence, thereby retaining traditional practices that preserve regional culture and open space values. The intimate and social spaces conducive to outdoor living and entertaining assimilate with the architecture and echo the site's naturalistic setting at 8,000 ft above sea level. In order to preserve the agricultural heritage of the valley, the design limited site disturbance, adhered …
Design-With-Nature For Multifunctional Landscapes: Environmental Benefits And Social Barriers In Community Development, Bo Yang, Ming-Han Li, Shujuan Li
Design-With-Nature For Multifunctional Landscapes: Environmental Benefits And Social Barriers In Community Development, Bo Yang, Ming-Han Li, Shujuan Li
Bo Yang
Since the early 1970s, Ian McHarg’s design-with-nature concept has been inspiring landscape architects, community and regional planners, and liked-minded professionals to create designs that take advantage of ecosystem services and promote environmental and public health. This study bridges the gap in the literature that has resulted from a lack of empirical examinations on the multiple performance benefits derived through design-with-nature and the under-investigated social aspect emanated from McHarg’s Ecological Determinism design approach. The Woodlands, TX, USA, an ecologically designed community development under McHarg’s approach, is compared with two adjacent communities that follow the conventional design approach. Using national environmental databases …
Community Planning Approach And Residents’ Perceived Safety: A Landscape Analysis Of Park Design In The Woodlands, Texas, Bo Yang, Shujuan Li, Bret R. Elder, Zhe Wang
Community Planning Approach And Residents’ Perceived Safety: A Landscape Analysis Of Park Design In The Woodlands, Texas, Bo Yang, Shujuan Li, Bret R. Elder, Zhe Wang
Bo Yang
This study compares community-park design and residents’ perceptions of safety in two subdivision communities in The Woodlands, Texas. The communities were built following two different planning approaches — the ecological approach and the conventional approach. Surveys have shown that residents generally feel safer in community parks built according to the latter approach. Using landscape metrics and home-to-park proximity indicators, we examine how different planning approaches affect park design and, as a result, influence residents’ perceptions of safety. We cross-validated the results with survey studies conducted over several years. The study findings suggest that park location, spatial configuration of woody vegetation, …

Bo Yang
The town of South Lake Tahoe experienced undisciplined development, which created traffic congestion, limited connectivity to recreational assets, and negatively impacted the scenic and environmental quality of Lake Tahoe and the region. In response, strict environmental regulations were developed, which subsequently ceased development activities. Faced with serious environmental and economic problems, residents, officials, and developers jointly revised development regulations and worked to strategically deploy development monies to give the town a new future. Today, the town's Park Avenue Corridor with its wide sidewalks, interconnected plazas, consistent architecture, gondola, intermodal transit center, street furniture, and integrated stormwater management is a national …
Cherry Creek North Improvements And Fillmore Plaza Landscape Performance Benefits Assessment, Bo Yang, Yue Zhang, Pamela Blackmore
Cherry Creek North Improvements And Fillmore Plaza Landscape Performance Benefits Assessment, Bo Yang, Yue Zhang, Pamela Blackmore
Bo Yang
The 16-block Cherry Creek North retail district was designed to be Denver's premier outdoor shopping area. Yet deteriorating infrastructure, tired aesthetics and competition from an adjacent indoor mall had led to steady decline. Fillmore Plaza in the heart of the district was no longer a desirable public space since being closed to vehicular traffic in 1987. The new streetscape strengthens the retail environment, preserves the district's history and character, improves identity, beautifies the area, provides new lighting, improves signage, and adds 20 "Art and Garden Places" for shoppers to relax and linger. The redesigned Fillmore Plaza is now a vibrant …

Assessing Planning Approaches By Watershed Streamflow Modeling:Case Study Of The Woodlands, Texas, Bo Yang, Ming-Han Li
Assessing Planning Approaches By Watershed Streamflow Modeling:Case Study Of The Woodlands, Texas, Bo Yang, Ming-Han Li
Bo Yang
The Woodlands, Texas, is well known as a town created following Ian McHarg’s ecological planning approach that uses soil permeability to coordinate development densities and land use. Very few studies have quantitatively measured the effect of this planning approach on stormwater management. In this study, watershed stream flow modeling was conducted to assess five hypothetical land use scenarios. These scenarios were compared with The Woodlands’ 2005 condition using the Automated Geospatial Watershed Assessment (AGWA) tool that simulates watershed long-term stream flow and peak discharges during single storms. The objectives are to: (1) assess The Woodlands development conditions during 1974–2005 on …

From Traditional To Today: Revelation From Chinese Gardendesign, Bo Yang, N J. Volkman
From Traditional To Today: Revelation From Chinese Gardendesign, Bo Yang, N J. Volkman
Bo Yang
China, like many other nations, struggled in the twentieth century with defining an indigenous landscape design tradition. This was particularly true in addressing urban open space design after China implemented the Open Door Policy in the late 1970s, when Chinese garden design traditions became largely neglected. The objective of this study is to determine whether the traditional design approach could still effectively serve as modern design inspiration. Built upon a previous study by Wu (1999), our study is a reflective critique on modern Chinese urban public space design. We compare major types of traditional and modern Chinese urban open spaces. …
Ecological Engineering In A New Town Development: Drainagedesign In The Woodlands, Texas, Bo Yang, Ming-Han Li
Ecological Engineering In A New Town Development: Drainagedesign In The Woodlands, Texas, Bo Yang, Ming-Han Li
Bo Yang
This paper presents a comparative study of two different drainage designs in a 10,930-ha new town development of The Woodlands, Texas. Open surface drainage by shallow grassed swales was used in the first two subdivisions that were developed with ecological approaches. Open surface drainage mimics the natural flow regime and is regarded to mitigate development impacts on watershed. In other later subdivisions, the drainage design shifted back to a conventional stormwater drainage system, that is, curb and gutter, drop inlet, and underground piping, known to concentrate stormwater and lead to downstream flooding. The objective of this study is to compare …
