RSMP Status and Trends: Characterizing urban nearshore sediment quality at the regional scale
Presentation Abstract
Title: RSMP Status and Trends: Characterizing urban nearshore sediment quality at the regional scale
Authors: Brandi Lubliner and Robert Black
Characterizing the effect of urban stormwater on natural environments is a complex and difficult task. In 2016, the Regional Stormwater Monitoring Program (RSMP - a new cooperative program that began in 2014 with funding from Washington State’s municipal stormwater permittees, and several state and federal agencies) will monitor nearshore sediment quality (and mussels) using a stratified random sample design that aims to detect and track changes in urban area nearshore conditions over time.
This monitoring will focus on a single landscape scale, the marine shoreline and nearshore parallel to the City and Urban Growth Area (UGA) in the Puget Sound to assess stormwater/land use impacts. The study design assumes that a) we will sample enough sites to produce Puget Sound-scale concentration estimates at a high confidence level (80-90%) and for potential stratification of samples into other categories (e.g., land uses); and b) the nearshore UGA assessment region is different than the Puget Sound wide or Urban Bay assessment regions already monitored by the state. Shorelines and nearshore areas in Puget Sound in urban and urbanizing areas are assumed to be more (or differently) influenced than shorelines and nearshore areas outside urban and urbanizing areas due to the stormwater management efforts required by state stormwater permits. This effort will compare data from prior marine sediment studies in the urban bays and region wide.
The probabilistic random stratified sampling design selected for this effort follows EPA’s site selection approach. The RSMP nearshore sites span the entire Puget Sound. The first year objectives are to characterize the status, spatial extent, and quality of nearshore marine sediments in the UGA assessment region. Results from this first year of sampling will be used to make recommendations for the trend program. The randomized study design is scalable and could expand to encompass the Salish Sea for a cross boundary trend program.
