that traditional drainage solutions often transfer problems further downstream, negatively im pacting the environment and water resources. Our stormwater expertise includes projects related to Clean Water Act initiatives such as compliance services for National Pollutant Dis charge Elimination System (NPDES) and Munic ipal Separate Storm Sewer Systems (MS4s). Our stormwater managers have more than 20 years of NPDES experience and have been respon sible for the development and compliance of hundreds of NPDES facilities from concept and design to construction and inspection. They have overseen many stormwater retrofit projects since the early 1990s when water quality im provements for old development were becom ing of interest to MS4 clients. Our stormwater professionals are experts in ap plying the State’s stormwater rules, including the guidelines in the State’s proposed Environmental Resource Permitting (ERP) Applicant’s Hand book. WSP has successfully implemented a num ber of major stormwater, drainage, restoration and retrofit projects applying best management practices (BMPs) to serve the unique needs of each project. We have a very good understand ing of retrofit design in areas of well drained soils. Our typical design approach first includes find ing conceptual locations for the most cost effec tive and appropriate stormwater BMP location. Our modeling efforts typically include repetitive model runs using an infiltration tool such as

PercPak in the ICPR software. Such tools allow us to exhaustively assess the most appropriate design for a BMP site and with these tools, actu al volume infiltrated or pollutant load removed can be computed. WSP has been involved with implementing and developing various structur al and non-structural BMPs. There are various forms that BMPs can take, such as stormwater ponds (wet or dry), grassy swales, inlet systems, and filter marshes to name a few.

Flood Study and Floodplain Management

Knowing where flood hazards exist is essential for the planning, management, and mitigation of flood damages. Today, most flood-hazard areas are unmapped, leading to uninformed decisions by citizens, and escalating public flood damages. The reasons these areas remain unmapped are related to limited budgets, and old technologies that are cumbersome to apply. Recent advances in Geographic Information System (GIS) technology, for the first time, are allowing for auto mated flood hazard mapping in a GIS environment. What that means to the end user is the end of cumbersome packages that oftentimes constrain the full power of the GIS environment. WSP, a long-term developer and user of automated Hydro logic & Hydraulic applications, quickly recognized the pow er of the Automated Floodplain Generator (AFG). The AFG, developed for the Multi-Hazard Map Modernization Program, facilitates improved delineations and introduces the concept of the living floodplain.

What is a Living Floodplain Theme? Because the AFG is hosted in a GIS environment, the re sulting flood boundaries are living. Over time, as improved data sources (topography, land uses, map revisions, etc), are brought into GIS, the AFG facilitates the rapid update of the flood boundary. This eliminates the expensive practice of throwing away the old study and starting over.

This capability can be applied either as a hazard mapping function, or through “what-if” scenarios as a planning function.

HYDROLOGIC RESTORATION ON THE LOWER SUWANNEE NATIONAL WILDLIFE REFUGE Dixie County and Levy County, Florida

Approximately 194 miles of roads and trails developed for the commercial timber industry across the 53,000-acre refuge serve as dikes and lateral diversions altering the natural flow patterns and restricting the flow of freshwa ter in ways suspected of truncating the salinity gradient of tidal creeks and concentrating Suwannee Sound salinity during dry periods. The overarching goal of the project was to restore the es tuarine balance of the system by providing a more natural flow exchange between the estuarine waters of Suwan nee Sound and its numerous freshwater tributaries, while simultaneously eliminating areas of repetitive unpaved road washouts during high water events. The goal was not to restore pre-development hydrologic conditions, but to focus on engineering measures to facilitate the natural delivery of fresh water from the Refuge to the estuary to benefit and enhance ecological functions. The project included online data collection, field recon naissance, development of a GIS modeling database, de velopment of existing conditions and proposed conditions hydrologic and hydraulic models, conceptual restoration designs, and opinions of probable cost for the proposed restoration alternative designs.

CITY OF OLDSMAR CLIMATE RESILIENCY PLAN Oldsmar, Florida

WSP worked with the City of Oldsmar to develop a Climate Resiliency Plan (CRP) for city-owned and

managed assets. To develop the CRP, WSP conducted a risk-based vulnerability assessment for city assets using future probabilistic storm surge, sea level rise, and pre cipitation data. This work included coordination with the University of Florida on development of a probabilistic flood model to represent future storm surge risks to the end of the century. Future precipitation values were generated by WSP’s climate team and included as inputs, with sea level rise im pacted tailwater conditions, into the stormwater model to gen erate scenarios for localized flooding from precipitation flood ing for various future precipitation events for a range of return periods. The combined technical analysis was used to generate probabilistic stressor values for use in the project risk assessments to identify impacts to 2100. WSP worked closely with city staff to create an inventory of risks to city owned assets associated with various water elevations. Measures were generated that identified the level of impact to asset use from various flood levels (minor to significant), and these measures were com bined with flood probabilities to generate a series of time-period recom mendations. This assessment created a simple three-dimensional analysis that looked at depth of flooding (not just presence) to determine impacts to the service of assets and city stakeholders. The resulting action-oriented plan establishes an investment roadmap for Oldsmar to follow to reduce risk to high-risk assets and change practices to incorporate resilience into City planning processes and investments. The project team also assessed the city’s Comprehensive Plan and National Flood Insurance Program (NFIP) Community Rating System (CRS) program and made recommenda tions for policy changes that could benefit the city during the transition to FEMA’s Risk Rating 2.0 program.

WETLAND RESTORATION INSPECTIONS ATLAS TACK SUPERFUND SITE Fairhaven, Massachusetts

The Atlas Tack Site was added to the National Priorities List (NPL) in 1990 as a result of past waste disposal practices from manufacturing processes that discharged wastes into adjacent wetland areas. The United States Environmental Protection Agency (USEPA) conducted Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) remedial activities at the site including the excavation and restoration of freshwater and saltwater contaminated wetlands. In 2009, Massachusetts Department of Environmental Protection (MassDEP) assumed responsi bility for long term operation and maintenance of the site from USEPA. WSP was awarded a task assignment in 2009 under the SARSS V con tract to perform regular and periodic qualitative and quantitative mon itoring inspections of restored freshwater and saltwater wetlands in ac cordance with the 2009 Final Operations and Monitoring Plan prepared by USEPA and implemented per the mandate of the Record of Decision. Inspections initially occurred monthly during the growing season but were reduced to semiannually in 2015. Wetland plant species composition and vegetative cover class are quan titatively evaluated using the Braun Blanquet cover abundance scale assessment method and Relevé quantitative data sheets. Inspections also include observations of fences, gates and erosion/sedimentation control measures in place. A monitoring report detailing the results of the in spection along with extensive photo documentation and recommended action items is prepared by WSP and submitted to MassDEP following each inspection. As a unique element of the inspections, WSP also oversaw the identifica tion and removal of exotic and invasive species. WSP also conducted two post remedial monitoring rounds of surface water and sediment sam pling which contributed to the successful restoration of saltwater wet lands/estuaries critical to restoring local ocean fisheries and native bird and plant habitats.
