This presentation will provide a basic overview of ground penetrating radar (GPR) and evaluate its emerging role in the damage prevention industry for protecting critical infrastructure and public works. Attendees will leave with an understanding of how the technology works, what utility locate data look like and how to interpret it, how GPR compares to other locating equipment, and the role of GPR in damage prevention with specific steps to maximize a successful GPR survey. In the overview of GPR technology, this presentation will summarize the mechanism that GPR uses to image the subsurface and then explore the two main variables that drive depth of location: antenna frequency and material properties. Next will be a review of several case studies from utility locating projects showing both 2D and 3D data. The comparison of these two views will help attendees understand the benefits and limitations of both visualizations. Then I will compare GPR to EM locators, focusing on the strengths and weaknesses of each and ultimately making the case that these are complimentary mapping techniques. Finally, this presentation will present a variety of ways that GPR can be used on locate projects including those with non-ideal conditions and offer a few steps to enhance the likelihood of a successful survey.The people who will benefit most from this presentation are managers of government agencies and engineering firms that conduct damage prevention projects and utility locates as well as those that are considering GPR technology or want to maximize its potential. In addition, locate technicians will find the discussion of GPR basics and the comparison to other technology useful.Learning Objectives: Investigate buried utilities to minimize potential damageExplain the limitations of GPR to clients and agenciesRecommend appropriate use of GPR in a variety of conditions
Read MoreThe factors that motivate an entity to address resiliency, as it relates to infrastructure, can vary widely – depending on how resiliency is defined and addressed in various geographic locations. In this program, we will share three different case studies, from three separate regions. We will also share the value of resilient infrastructure, and discuss how resilient infrastructure has been beneficial.

In responding to emergencies, rapid organized actions from public works are critical. The Utah APWA Chapter Emergency Management Committee recognized the need to develop an alliance among state-wide public works agencies to provide assistance across jurisdictional boundaries. Participating agencies that have experienced a natural or man-made disaster can obtain emergency assistance in the form of personnel, materials, equipment or other associated services from other nearby agencies. Learn about the components of the Utah mutual aid agreement and how agencies in your area can set up something similar.Learning Objectives: Initiate an inter-local agreement to address emergencies across jurisdictional boundaries.Incorporate outside public works agencies into their emergency planning and preparation.Acquire additional resources to assist their public works agencies in times of need.

Palm Beach County, Florida, recently completed the design and construction of a renewable energy facility. This presentation will focus on the technological, as well as financial, considerations of this project. Discussion will include these factors: how to compare waste-to-energy technology to other popular waste management options including landfilling, aerobic digestion and others; how the county was able to overcome the typical obstacles for this type of facility, including site selection, financing, and permitting; and how design elements were incorporated into the project to allow it to better co-exist with the natural environment and meet stringent water resources and air pollution limits.Learning Objectives: Evaluate solid waste disposal options.Manage the site selection, permitting and financing associated with development of a new waste to energy facility.Design a waste to energy facility to coexist with nature and the community.

Orange County, California's reorganization of public works included the movement of 215 positions between service areas, deletion of 57 vacant positions, addition of 45 new positions at lower level classifications, and 7 filled position reallocation requests. As you might assume, the implementation did not come without opposition and impacts from the affected staff. However Orange County Public Works defied the odds and successfully rolled out the restructuring program. They continue to work with the management team, staff, and unions to ensure a full transition and have been acknowledged as a trendsetter within the county and region for organizational solutions.Learning Objectives: Accomplish a massive organizational restructuring.Collaborate with staff to implement department-wide change efforts.Gain buy-in and support from elected officials, management, staff, and unions for organizational change.

Green Infrastructure Solutions for Stormwater ManagementPlanned and hosted by APWA's Water Resources Management Committee Don't miss these interesting case studies about practical Green Infrastructure applications. Discover what's working and how you will be able to adapt these approaches to your area and systems.Stormwater Quality Retrofits Made Practical Comparing and choosing stormwater quality retrofit alternatives and strategies is challenging. Representatives from the City of Eugene, Oregon, will discuss the benefits and challenges of different water quality alternatives which include rain gardens, large neighborhood scale swales, and pervious concrete pavement. The City of Eugene is an NPDES Phase I permit holder with years of experience implementing stormwater quality improvement retrofit projects. They'll share the lessons learned and innovative solutions.Town Creek Culvert – Green Infrastructure in the Urban Core Stormwater projects have not traditionally been a major component of the Clean Water State Revolving Fund (CWSRF) awards, but the City of Greenville, North Carolina, successfully obtained a grant for the Town Creek Culvert project by including green infrastructure components. The routing of this culvert through the urban core of the city is also being impacted by the construction of a highway which is adding 45 acres to the culvert's watershed. The culvert will discharge into a regenerative stormwater conveyance (RSC) that will remove nutrients as well as reduce velocities. Other green infrastructure features include a bioretention area upstream from the RSC, a permeable paver system, wetlands, tree boxes, and another smaller RSC.Detention Basin Retrofits for Stormwater Quality Treatment The City of Springfield, Missouri, has embarked on an innovative and unprecedented integrated plan to prioritize future environmental programs. One of the goals of the integrated plan is to find relatively low costs methods of improving water quality in area streams. Most of the existing stormwater detention basins in Springfield, as well as most communities in the Midwest, were designed with the single purpose of providing flood control. A total of 178 existing detention basins are evaluated for retrofit feasibility considering two options: 1) downsizing the outlet structure to achieve additional water quality treatment; 2) downsizing the outlet structure to improve the infiltration rate of the basin and adding a vegetative component.Conventional stormwater best management practices (BMPs) have been commonly applied in Florida since the early 1980s. However, with the realization that conventional BMPs do not always achieve the desired pollutant load reduction, coupled with the need for practices that are better-suited for smaller spaces and retrofits in highly urbanized areas, GI/LID practices were added to the BMP palette. Challenges met and overcome included accommodating these practices into the existing regulatory/permitting process and adapting them to local hydrologic conditions.Learning Objectives:Identify stormwater retrofit alternatives and strategies.Describe green infrastructure practices that are useful in pollutant load reduction.Determine which green infrastructure approaches would best fit your local hydrologic conditions.
