“…For this study, 66 global waterbody guidelines (see Supplementary Information Table ) were sourced and assessed in relation to their design criteria regarding algal blooms. Approaches and philosophies for stormwater management have a range of names around the world (Radcliffe, 2019) including Water Sensitive Urban Design (WSUD) (Department of Planning and Local Government, 2010; Lewis et al., 2015; Melbourne Water, 2005d), Best Management Practices (BMP) (Pennsylvania DEP, 2006; US EPA, 2004), Low impact development (LID) (Dorman et al., 2013; The City of Edmonton, 2014), Sustainable Urban Drainage Systems (SUDS) (CIRIA, 2015; Martin et al., 2000), Alternative Technologies (Armitage et al., 2013), and Sponge Cities (Ministry of Housing and Urban‐Rural Development (MOHURD), 2014).…”

Constructed shallow waterbodies are often designed and built to limit harmful algal blooms in urban regions. Efforts to reduce algal bloom occurrence in these waterbodies have largely focused on waterbody design, catchment criteria and onsite engineering options. However, many constructed shallow waterbodies that comply with design guidelines still experience harmful algal blooms. Identifying the knowledge gaps in current guidelines and examining their recommended design criteria can improve their effectiveness to reduce algal outbreaks. Here, we reviewed 66 global guidelines and identified common design criteria. The use of a ‘one size fits all' empirical approach and dated literature are common issues associated with the design criteria recommended. Further, only approximately one third of the guidelines that were analyzed directly mentioned harmful algal bloom‐related design criteria. To test the validity of these design values in a real‐world setting, the suitability of design factors in limiting harmful algal blooms was assessed by analyzing 222 shallow waterbodies monitored over a 9 year period in southeastern Australia. The site analysis indicated that macrophyte area to surface area ratio, shoreline development index, and fetch are the three most influential single design factors associated with harmful algal bloom reduction. The analyses highlighted the ineffectiveness of the existing design criteria globally, with blooms occurring even though some waterbodies were designed in accordance with recommended parameters. The analysis suggested that understanding interactions between multiple design factors may be a useful approach, for example, when considering the macrophyte area to surface area ratio in combination with the shoreline development index.

“…In Australia, and elsewhere across the world, urban stormwater design has grown and matured enormously in the last 20 years. Achievements include the development of national standards and guidance on modelling and risk assessment (Ball et al, 2019), innovation in water sensitive urban design (Brown et al, 2016), and extensive work to reduce the impact of urbanisation on the natural environment while maximising quality of life for residents (Radcliffe, 2019).…”

When urban stormwater meets high groundwater

New land releases in the Perth Region on Western Australia’s Swan Coastal Plain are increasingly constrained by seasonally high groundwater (within 4m of the land surface). The measurement, modelling, and management of the effects of urbanisation in these high groundwater environments remains a challenging problem. To address this problem, the Cooperative Research Centre for Water Sensitive Cities (CRWSC) funded the “Knowledge-based water sensitive city solutions for groundwater impacted developments” Integrated Research Project, IRP5. In 2019, this project convened an Expert Panel to assess best-practice, and make recommendations to land development, engineering consulting, regulatory and advisory stakeholders. The Expert Panel explored strategies for groundwater risk assessment and provided technical guidance for measuring, modelling and predicting changes in groundwater as urbanisation progresses. It also obtained extensive input from stakeholders on the need to reduce the costs and risks of urban development in sites with high groundwater. In this paper, we argue that, by integrating technical best-practice groundwater assessments with design innovations and reforms to governance, urban development on high groundwater sites on the Swan Coastal Plain can minimise the current reliance on large volumes of sand fill. Although challenging, shifting to a low-fill development paradigm would represent a triple-bottom-line “win” for developers, homeowners and the environment.
