As many cities across the country have struggled to meet changing recycling market conditions, the City of Phoenix found a solution to this issue through a public and private partnership. This partnership was established to assist with the upgrade of the North Gateway MRF to ensure that the city was able to meet new industry standards, which includes more stringent commodity specifications (residual requirements) and change in inbound material composition. The North Gateway Transfer Station (NGTS) processes recyclables from North Phoenix, the City of Peoria, and the City of Prescott. The $4.5 million upgrade to this facility was funded by a $3 million no-interest loan from the Closed Loop Fund, $1 million from the City of Peoria, and the remainder was covered by city funds. Upgrades to NGTS began in September 2019 and concluded in December 2019. Equipment upgrades at the facility included two new anti-wrap disk screens, two new optical sorters, a drum feeder, expansion to the pre-sort line, critical infrastructure upgrades to the electrical and fire life safety systems, and a ballistic separator. Benefits from the upgrade include a substantial improvement of the capture of glass, paper, PET, OCC and aluminum; the ability to achieve tighter material quality specifications; 50% improvement in MRF throughput (processing speed); increased inbound processing capacity due to increased throughput; reduced residuals sent to landfill; the ability to temporarily process the City of Scottsdale’s recyclables since their MRF burned down in 2019; the ability to temporarily shoulder recyclables from 27th Avenue transfer station as this MRF underwent baler replacements over two weeks; and the ability to process more fiber products due to the increased demand of cardboard and paper during the COVID shutdown. None of these benefits would have been possible without the upgrades.
Read MoreIn this Point-Counter-Point debate-style presentation, two traffic operations engineers will explain why roundabouts are a leading design solution versus why traffic signals rule the intersection control world! Each side will present data on traffic volumes, traffic flow, safety, operations and maintenance, expandability and affordability for roundabouts in series versus intelligent traffic signal corridors. They report, you decide, in the Great Intersection Debate of PWX 2021.
Read MoreIn an era of data-driven decision-making, it is easy acquire data about so many things. The entire discipline of asset management is predicated on first acquiring condition data about your organization's infrastructure assets. But what about our most important asset, the people that do the work of public works? How do we know what our employees think of their own workplace? How do they feel about it? Find out how to measure the morale of your workgroup with a simple survey that directly informs management of what our co-workers think and feel about the workplace. Designed around Maslow's hierarchy of needs, the survey results instruct the manager on the best next step to take to improve morale in the workgroup.
Read MoreIn August of 2014, Washtenaw County Water Resources (WCWRC) adopted new rules requiring infiltration of the 90th percentile design storm for all new site plans. The rules permit an alternative of traditional detention storage at 120% of calculated 100-year storm capacity only if WCWRC determines that soils testing was adequate and found inadequate infiltration capacity. In 7 years, nearly 250 sites have been reviewed, and this presentation will describe the review requirements, stakeholder engagement process, outcomes, and win-win benefits to water resources AND the development community. Nearly 25% of sites have been able to eliminate detention and infiltrate the entire 100-year storm. By definition, using the 90th percentile storm (1″ in the study area) returns 90% of annual rainfall into the groundwater, a tremendous benefit to urban and suburban rivers, lakes and streams. Third party information will be provided to demonstrate that using the 90th percentile storm also provides more reliable TSS treatment than detention or mechanical separators. In most urbanized areas, communities require stormwater management with one major goal being reduction of impacts due to development. It is well known that detention basins can simulate pre-development runoff rates but they do not simulate pre-development conditions in five (5) areas. First, detention does not address added volume and thus contribute to downstream water quantity issues. Second, reduced infiltration from natural conditions is beneficial to water quality through groundwater recharge for cooler, stream inputs, steadier base flow, and TSS removal. Third, detention basins have fixed capacity and therefore very limited resiliency. Fourth, detention basins sized for 100-year storms tend to require 5-10% of the contributing land area. Fifth, think about every basin you have seen at an apartment complex and how many geese and ‘tootsie rolls’ you see surrounding them. Ewww.
Read MoreOn October 10, 2018, Bay County was struck by the third-most intense Atlantic hurricane to make landfall in the United States. It was the first Category 5 hurricane on record to impact the Florida Panhandle and produced the nation’s largest debris disaster. The storm was attributed to at least 74 deaths and caused an estimated $25.1 billion in damages. Bay County, Florida, received the eye of the storm and the Public Works Department learned many important lessons both pre- and post-storm. Some of the lessons discussed in this presentation include: pre disaster staging; post-disaster staging; communications; FEMA paperwork and FEMA consultants; Disaster Management Sites (DMS); feeding and lodging staff and their families; emergency contracts; post-disaster traffic flow; FLAWARN; post-storm equipment needs; long-term recovery. Two years after Hurricane Michael, Bay County is still recovering, but plans are being put in place to help.
Read MoreTo meet the demand for 5G telecommunications, companies will be erecting hundreds of thousands of small cell towers–often TWO towers per streetlight in most communities. Most public Works agencies will do nothing, others have learned how to make MILLIONS from the opportunity and transform their agencies using smart technologies. Now, post-COVID-19, teleworking and the demand for 5G/broadband is skyrocketing. Installing hundreds of new towers in each city will create both incredible opportunities and unprecedented problems for public works officials. Many agencies are adopting innovative strategies to not only manage this “tsunami”, but are even partnering with the telecommunications companies, municipalizing, and re-purposing their street lights and traffic signal systems and charging for each of the hundreds, or thousands, of new towers, creating millions in new sources of revenue. Other cities have been even more visionary. They are “flipping” their annual streetlight systems from “must pays” (liabilities) to “cash cows”, or revenue streams. This session addresses these competing priorities: accelerating 5G: post-pandemic; creating resilient, critical “intelligent infrastructure”; ensuring healthy RF radiation levels; generating millions in new revenue; installing/leasing excess city fiber optics for cash; leasing streetlights as transmitter sites; improving traffic signal coordination; setting aesthetic standards; and futureproofing and Smart City strategic planning
Read MoreThis session details the experience of a large, full-service municipal public works department, the City of Olathe, Kansas, going through the Department of Homeland Security’s Cybersecurity and Infrastructure Security Agency (DHS CISA) Protective Services and Cybersecurity Assessment processes. It features a roundtable including both public works and emergency management professionals as well as members of DHS CISA Protective Services and Cybersecurity groups. The discussion will have two areas of focus. First, participants will discuss specific critical areas of risk assessment, cyber security, employee safety, and continuity of operations. Specific attention will be paid to basic risk assessment principles, SCADA vulnerabilities, physical security and active shooter training, and second and third order threats to service delivery. Second, participants will have an open discussion on the DHS CISA assessment process as it pertains to the unique needs of public works, both areas of strength and opportunities for improvement. Finally, the presentation will provide attendees the opportunity to hear from all three stakeholder groups involved in this process and gain an awareness of how this free program may be of benefit to their agency.
