Capturing and Conveying Stormwater
Capturing and Conveying Stormwater
Presentation will include and array of Cast Iron options to collect and convey stormwater using NEI 150 years of expertise. We will showcase a multitude of grate options that will offer maximum water capture, while still being vehicular and bicycle safe. we will highlight decorative trench options that will add an aesthetic appeal to pedestrian pathways while still conforming to ADA guidelines. We will present on our "Hydrovent" manhole cover that is designed to safely open and release excess water during storm events when the underground systems becomes compromised. Thus, preventing damage to the underground structure and keeps the cover from floating away leaving an open manhole. Lastly we will speak on Neenah Foundry's green initiative, in which all our products are 85% or higher post consumer materials along with how our foundry's process emits only 99% water vapor during production into the atmosphere.

Leveraging Multiple Benefits of Stormwater Capture and Use for Oahu
Leveraging Multiple Benefits of Stormwater Capture and Use for Oahu
The practice of harvesting stormwater involves the planned beneficial use of rainwater harvesting and stormwater runoff, which is water from rainfall that is in an engineered feature or running over the ground surface. Stormwater harvesting varies considerably across the U.S., and even within a given region. Figure 1 provides a generalized graphic overview of stormwater capture and use practices. The field of stormwater harvesting is evolving and expanding as utilities and communities consider viable alternatives to increase water supplies, improve resiliency of their water resources, and find multi-benefit and innovative approaches to addressing regulatory and water quality challenges. As communities seek to improve resiliency and provide habitat, open spaces and recreational opportunities, stormwater harvesting projects are receiving more interest. Utilities across the U.S. are evaluating options to better manage and integrate water resources due to challenges associated with increasingly stringent regulations, water scarcity, competition for limited supplies, flood risks, water pollution, and impacts of climate change. The potential for stormwater capture and use provides a significant opportunity to address these challenges. Stormwater capture and use can augment water supplies, improve water quality, and provide runoff reduction. Through current research a process for developing stormwater capture and use programs is in the works. This would allow agencies to plan stormwater capture and use by: • Aligning key geographically-driven guiding opportunities such as: Climate – how much is available and when? Use – when is it needed most? Groundwater – where can it be stored? • Then selecting local drivers such as: Water quality Water supply/scarcity Flood mitigation/CSO • Then determining program characteristics within state, local regulations by zoning type This presentation will review some case studies of stormwater capture and use projects that demonstrate various drivers, obstacles, approaches, and benefits; and how these applications may support green initiatives. The City and County of Honolulu participated significantly in the study by collaborating with the research team on five candidate locations for stormwater capture and use on Oahu. In addition, details of ongoing research on stormwater capture and use will be presented.

Sensitivity of TMDL Process to Dramatic Changes in Land Use on Oahu
The purpose of the TMDL process is to improve water quality of impaired and threatened waters identified by the State (the 303(d) list) in compliance with the Clean Water Act. The TMDL calculates the maximum amount of a pollutant (typically nutrients, turbidity or suspended sediment) that can be contributed by various sources within the watershed while meeting water quality standards and then challenges contributors to find means (BMPs) to meet these pollutant reduction goals. This presentation discusses the changes in near-shore water quality that accompanied the transition from furrow to drip irrigation of roughly 9,000 acres of sugar land and then the near-complete cessation of agricultural activity in the Ewa Plain region of Oahu between 1973 and 2008.
A tremendous mass of fertilizers was historically applied to the sugar land in Ewa. Between 250 to 400 pounds of nitrogen and 100 to 500 pounds of phosphorous were applied to each acre cultivated. The fertilizer not captured by the sugarcane crop would have been carried in groundwater flows emerging in the intertidal zone around the Ewa plain. The crops were irrigated by water produced by a combination of artesian basal wells and shallow wells dug into the Ewa caprock. Up until the late 1970s, the sugar crop was irrigated using the furrow method, which involved flooding the fields between 20 to 40 times over the two-year crop cycle with between 4 to 10 inches of water applied during each irrigation period for an average of 48.3 mgd. The advent of more efficient drip irrigation methods reduced this flow to 2.15 mgd in 1986. By 1994, all irrigation to Ewa Plain cane fields had ceased and the total groundwater withdrawal in the area dropped to around 3 mgd.
The State has monitored near-shore water quality at Ewa Beach Park since 1973. During the furrow and drip irrigation periods, the “wet” Hawaii water quality standards for Open Coastal Waters applied to this site since the freshwater discharge per mile of shoreline exceeded the 3 mgd criteria. The 10% and 2% Not to Exceed standards for nitrogen, phosphorous and turbidity are 250/350 parts per billion (ppb), 40/60 ppb and 1.25/2 NTU, respectively.
Median and mean nitrogen and phosphorous concentrations measured at the Ewa Beach Park did decline from the furrow, to drip, to post-agricultural periods: median/mean concentrations (ppb) (Nitrogen) - (Phosphorous) (245/316) - (49/58) (furrow); (200/227) - (25/38) (drip); and (100/138) - (14/16) (post-agricultural). However, the magnitude of the decline in measured nitrogen and phosphorous concentrations in the nearshore environment was relatively subtle considering the magnitude of the land and water use changes that occurred between 1973 to the present. Based on this finding, it is unlikely that statistically significant changes in water quality will be measured at other TMDL sites established in Hawaii, where individual contributory activities or land uses of concern typically represent less than 5% of the total watershed area.

Hawaii's Nonpoint Source Rules
Hawaii's Nonpoint Source Rules
While point source pollution such as wastewater treatment plants, construction sites, and municipal storm drain systems have major impacts on water quality, many have begun asking, “What about the loss of our streams and wetlands? How about storm water pollution from sources such as large State lands and forests?” At the DOH, we’ve been thinking a lot about these things too, and have been working on a system to address them. In June 2021, Governor Ige signed into law Hawaii’s first administrative rules authorizing the regulation of nonpoint sources of pollution. This short presentation will go over some nonpoint source basics and give an introduction into Hawaii’s first rules developed to prevent and control pollution from sources not covered by the Clean Water Act’s National Pollutant Discharge Elimination System regulatory program.

Green Stormwater Infrastructure (GSI) at the Ala Wai Golf Course and the Lessons Learned
Green Stormwater Infrastructure (GSI) at the Ala Wai Golf Course and the Lessons Learned
A major concern of the City and County of Honolulu (City), Storm Water Quality Division (SWQ) is the improvement of water quality throughout the island of Oahu. To address this concern, the City has implemented regulations that require the inclusion of GSI into select new development and redevelopment projects. During GSI projects, project setbacks and design oversights can result in unexpected and detrimental consequences. However, these consequences can be mitigated through adequate planning and learning from previous experiences.
Two (2) recent GSI projects, one completed and one in its final stages of completion, have been constructed in the Ala Wai Golf Course by SWQ and includes GSI elements in the form of detention basins, retention basins, and pervious pavers. Issues were identified in the projects, both during construction and upon the completion of construction, which highlight the importance of proper planning within the design phase. Appropriate planning negates the need for redesign during construction which can increase cost and delay construction, which was experienced during the construction of the pervious pavers and retention basins. Additionally, planning and design oversights can result in GSI that is difficult to maintain, such as inaccessible structures and inadequate equipment necessary to undertake maintenance.
Upon project completion, revisiting and reviewing project pitfalls in order to document lessons learned can be a vital technique to ensure similar issues do not occur in future projects. Reflection on the Ala Wai Golf Course projects has been conducted in order to provide benefit to both municipal and private future GSI construction projects.

Stormwater Quality Monitoring in the MS4 and Receiving Streams
Stormwater Quality Monitoring in the MS4 and Receiving Streams
The City and County of Honolulu Department of Facility Maintenance (City), in compliance with their National Pollutant Discharge Elimination System permit, continues to monitor stormwater discharge from their Municipal Separate Storm Sewer System (MS4) to assess its chemical impact on state receiving streams. This monitoring is ongoing. The results of the first five years of monitoring from 2015 to 2020 are presented here. Over this time, 196 storms were sampled at 13 MS4 End-of-Pipe and stream monitoring sites across Oahu. The sites encompassed a variety of land uses (residential, institutional, and conservation) and site conditions on both windward and leeward sides of the island. Each of the sampled storms was characterized by its Event Mean Concentration (EMC) representing the average flow-weighted pollutant concentration during a given storm. The monitored pollutants included nutrients (nitrogen and phosphorus), metals, total suspended solids, and turbidity. \ The findings indicate that storm water quality varies widely across the island. Some areas were found to be pollutant “hotspots” while others had relatively “clean” storm runoff. The micro-climate of a particular area (rainfall abundance and frequency) was clearly an important factor in driving the EMCs, with drier areas tending to have more impaired runoff than wetter areas. The study also indicated another important factor was the presence of human-induced dry weather flow in the storm drain, e.g. “runoff” from residential sprinkler systems or the illicit discharge of swimming pool water into the MS4. Such flows effectively cleaned the pipes, keeping EMCs low. Finally, there was also limited evidence that certain types of land use can play a role in storm water quality, although land use was clearly not the overriding factor. It was determined that the City’s MS4 can have either a positive or a negative effect on the existing water quality of the receiving stream, depending on pollutant. In the case of nutrients and sediment, the impact was positive since the MS4 discharged lower concentrations of these pollutants relative to the stream, causing a dilution effect. However, in the case of metals, the impact was negative since the MS4 consistently had higher metals concentration than the receiving stream.

Effectiveness of Inlet Protection Measures - Fact or Fiction?
Effectiveness of Inlet Protection Measures - Fact or Fiction?
When reviewing sediment and erosion control (S&EC) requirements, one will find criteria for inlet protection measures. For example, Chapter 11-55, Appendix C, Section 5.1.2.9 of the Hawaii 2019 Construction General Permit (CGP) requires the installation of inlet protection measures to remove sediment from construction site discharges prior to their entry into the inlet of a storm drain system. This emulates what exists in EPA’s 2022 CGP. What reviewers and designers need to know is the effectiveness of inlet protection measures to capture sediment in runoff waters. The predominate inlet protection method found on active construction sites involve installing barriers in front of storm drain inlet openings. These Best Management Practices (BMPs) must be pervious, cannot float and be able to withstand the impact of flood discharges. What reviewers, designers, and contractors need to acknowledge is that using temporary barriers as inlet protection measures do little to minimize the discharge of sediment in runoff waters flowing into storm drain systems. This presentation will demonstrate why installing barriers in front of inlet openings do not provide effective inlet protection. It will show that only at “sump” inlets might circumstances be favorable for capturing sediment from construction site discharges before they enter a storm drain inlet. Participants will also find out why installing barriers in front of “on-grade” inlets results in capturing even smaller amounts of sediment from discharge waters. These findings impact developments that have numerous “on-grade” inlets! Specifically, requiring the installation of temporary barriers in front of every curb opening does little to provide optimal conditions for capturing sediment out of construction site discharges. The presentation will also evaluate alternatives to barriers and why accountability by reviewers and designers must exist as they approve and develop S&EC plans that include inlet protection methods. Specifically, these individuals must be cognizant of BMP limitations and how their use can either optimize or impede the capture of suspended particles found in sediment-laden discharges. Only with good planning will effective and practical inlet protection methods reduce the discharge of sediment into storm drain systems from active construction sites.

PaveDrain Lessons Learned in planning, design and construction
Stormwater management can be an expensive infrastructure cost in its own right. Every activity worth doing has a learning curve.
The PaveDrain® System is a sustainable permeable stormwater BMP that allows for a reduction or elimination in stormwater infrastructure costs while minimizing environmental impact. However, there still needs to be collaboration between designer, constructor, and maintainer so the proverbial “problems flow downhill” can be turned into “It just keeps infiltrating into the ground!”
Several Hawaii based PaveDrain projects as well as some mainland projects of 5+ years will be discussed.

Policy Basis for Incentivizing Green Infrastructure Implementation in the City of Seattle through Partnerships
Jacobs is helping Seattle Public Utilities (SPU) expand the use of green stormwater infrastructure (GSI) approaches to meet community and system needs-- like flooding, sewer backups, CSO’s, and poor receiving water quality. Doing so requires building innovative, cross-sector partnerships that leverage investments, accelerate and amplify existing work, and support a broader set of community outcomes than SPU would be able to deliver alone. Partners may include community groups, other City departments, private development, or any party interested in delivering a GSI project. A foundational component for this work is the ability to financially incentivize potential partners to design, construct and maintain GSI. SPU’s capacity to engage the broader community in GSI work requires greater certainty for potential partners around where SPU can partner, specifically where SPU can provide funding for GSI projects. Relying on results from past planning efforts, most recently the Wastewater System Analysis (WWSA) and Drainage System Analysis (DSA), that indicate where system problems are likely to exist, SPU aims to create a searchable map to proactively engage potential partners and leverage collective investment to build GSI on parcels and public rights-of-way (ROW) across the City. This presentation will provide background on the development of the stormwater performance criteria, geographic eligibility maps for GSI program partnering dollars, and an in depth discussion of the unit cost basis. SPU’s GSI Program has developed a unit cost basis policy that establishes what SPU will pay for managing a unit of stormwater. This policy was developed through a comprehensive review of DWW capital project costs, as well as a survey of existing partnering programs at peer municipalities. Attendees will have a better understanding of the processes and development of policies for green stormwater infrastructure partnerships.

Top 4 Construction Site BMP Deficiencies as Noted by Third Party Inspectors - How Choose, Install, and Maintain Stormwater BMPs to Reduce Potential Discharges
With the numerous options for stormwater BMPs out there, the correct choice for your particular construction project could be the difference between the appropriate level of protection or a critical discharge into the MS4 and potential fines. The correct choice, installation, and maintenance of a construction project’s stormwater BMPs can provide acceptable protection and reduce the potential for a discharge into the MS4. This presentation will go over the Top 4 most frequently seen BMP deficiencies as noted by the Jacobs Third Party Inspectors (3PI). With the information provided in this presentation, the 3PI Team’s goal is to see a reduction in deficiencies relating to perimeter controls, storm drain protection, concrete waste management, and sediment track. Over the past seven years, the 3PI Team from Jacobs have inspected projects ranging from Capital Improvement Projects to residential home. They have covered industrial, commercial, public, and private construction projects throughout the Island of Oahu. With a combined knowledge of over 35 years in the environmental and construction industry, this presentation will highlight the most frequently observed and avoidable deficiencies. This presentation applies to all levels of the construction process. From the planning and engineering phase of choosing the appropriate BMP for the terrain and the protection the BMPs provide to the installation and maintenance of those BMPs by the on-site Erosion and Sediment Control Plan Coordinator. The goal of this presentation is to equip the audience with the knowledge to reduce the number of deficiencies relating to the Top 4 most frequently seen BMP deficiencies.

This presentation will describe the decades of observations of unexplained, stormwater-linked mortality in Pacific Northwest Coho salmon and our efforts to find the chemical/s causing the toxic response. Here, I will describe our efforts to detect and identify chemical contaminants in roadway runoff, resulting in the identification of "6PPD-quinone" as the primary causal toxicant for coho mortality events. 6PPD-quinone is highly toxic and because it comes from a common antioxidant chemical "6PPD" used in all tires, it is ubiquitous in roadway runoff as well as particulate matter and soils near roads. Here we discuss its formation, occurrence, and implications for stormwater management and ecological health, as well as the role of tire rubbers in contributing many chemicals to waters near roads.

Erosion and Sediment Control Plan (ESCP) Coordinator Retrospective: A Look at Some Common Issues
The main purpose of this presentation is to provide a retrospective of common issues that the Erosion and Sediment Control Plan (ESCP) coordinators go through after the permitting phase, and through the permit closure process. The Erosion and Sediment Control Plan (ESCP) review process has been a requirement for review for projects going through the City and County of Honolulu (City) permit review starting in August 2017 which requires the review of Best Management Practices (BMPs) to reduce pollutants to the Maximum Extent Practicable leaving from permitted construction projects and into watersheds – which includes the City’s Municipal Separate Storm Water System (MS4). The ESCP coordinators manage the implementation and maintenance of the BMPs from the start of the project, until the final inspection. Through a short questionnaire sent out to random ESCP coordinators for projects which completed the Erosion and Sediment Control Plan review processes (Category one or higher) between January 2021 through June 2021- the retrospective will allow the ESCP coordinators to share their experience on three phases - the notice to proceed/Best Management Plan (BMP) setup, the construction activity phases (maintaining of the BMPs) / monthly inspection reports, and the closure process / completing the final inspection and letter of compliance.

Stormwater Pipeline Inspections: Quick and Dirty
Stormwater Pipeline Inspections: Quick and Dirty
Climate change has resulted in frequent and intense rainfall events that increase stormwater runoff in Hawaii. These events exacerbate the deterioration of aging stormwater infrastructure and often accelerate buried pipeline failures. The sink holes, which result from pipeline failures, damage real property and municipal roadways and ultimately risk public health and safety. Brown and Caldwell (BC) in collaboration with the County of Maui has developed a quick and cost-effective method of inspecting and defining stormwater conveyance infrastructure conditions. This inspection method allows the municipality to develop a defensible and sustainable pipeline replacement and rehabilitation program that proactively addresses the highest risk pipelines before failure occurs. The quick and cost-effective method combines the use of a pole-mounted zoom camera system and condition rating guidelines per the National Association of Sewer Service Companies (NASSCO). The pole-mounted zoom camera system, which is portable and lightweight, does not require pipelines be cleaned prior to inspection. Moreover, the camera system allows the 2-person field crew to visually inspect the inside of manholes and buried pipe from the ground, thus avoiding confined-space entry. The field crew assigns structural and operational condition ratings based on the visual data gathered by the camera system. Ratings, video and photo data gathered from inspections is saved and uploaded to the County computerized maintenance management system (CMMS) for future use or internal work orders. The inspection method has resulted in a cost-effective and on-going County wide stormwater conveyance infrastructure condition assessment. Results of the condition assessment inform a risk-based prioritization of the County’s annual pipeline repair and replacement CIP budget.

Estimating the Impact of Climate and Vegetation Changes to Runoff Risks Across the Hawaiian Landscape
Estimating the Impact of Climate and Vegetation Changes to Runoff Risks Across the Hawaiian Landscape
Changes in land cover caused by habitat conversion and invasive species can alter soil infiltration capacity and increase runoff and erosion, negatively affecting lands across Hawaiʻi. Reduced infiltration, the soil’s ability to allow water through it, may lead to serious consequences including terrestrial habitat damage by erosion, aquatic habitat damage by sedimentation, downstream damage by flooding due to storm flows from overland flow, or runoff. To help understand potential damage, we calculated the probability of rainfall runoff across the Hawaiian landscape, by comparing the probability distribution of current and future projections of rainfall frequency with the land cover-specific probability distribution of infiltration capacity. This was done by characterizing soil infiltration capacity based on different land cover types (bare soil, grasses, and woody vegetation) and comparing them to the frequency of large rainfall events under current and future climate scenarios. With that, we were able to map the potential risk of runoff across the main Hawaiian Islands. While smaller runoff analyses have been done for specific watersheds, no previous work has taken this landscape level approach. These calculations of potential runoff risk were completed for current climatic conditions as well as a future climate scenario. Not only can these runoff risk maps be used for current management planning purposes, the future scenario can be applied to proactively address further potential damage from runoff. This information is pertinent to federal, state, and non-governmental land managers and city planners alike to understand how changes in land cover can influence runoff and erosion, which can be both ecologically costly and result in infrastructure, health and economic impacts.

Cooperative, Multi-Entity Stormwater Management for MS4 Compliance in Census 2020 Urbanized Areas “Hawaiian-style”
Cooperative, Multi-Entity Stormwater Management for MS4 Compliance in Census 2020 Urbanized Areas “Hawaiian-style”
The applicability of MS4 stormwater permitting requirements is based on Census designated urban areas with specific population density. The US Census Bureau published an update to Urban Area Criteria effective 03/24/2022. A change in this definition could affect which Hawaii municipalities are "in" or "out" and potentially if they are Phase1 or Phase 2. Regulated small MS4s (Phase 2) are those located in an "urbanized area" as defined by the Census. Phase 2 general permits typically require implementation of 6 minimum measures for storm water quality improvement: public outreach, public involvement, construction site runoff control, post-construction runoff control, illicit discharge detection and elimination, and municipal pollution prevention practices. For those entities that become newly-minted small MS4s based on the updated Census designation, the Middle Rio Grande valley in New Mexico could provide a model for working cooperatively to reduce the cost of compliance. Twenty-three Middle Rio Grande entities together made recommendations to the EPA for a watershed-based MS4 General Permit. The resulting permit incentivized small MS4 to work cooperatively to achieve the minimum measures. EPA Region 6 considered the Middle Rio Grande watershed-based permit so successful that it was used as the basis for the state-wide Phase 2 general permit. How Hawaii could apply the lessons learned from 6 years of collaborative stormwater management will be outlined in this presentation.

Biofiltration Design Planning - The Good, The Bad and The Ugly
Biofiltration Design Planning - The Good, The Bad and The Ugly
Bioretention and biofiltration systems are the most common Low Impact Development systems used on land development and retrofit projects under the current City and County of Honolulu Stormwater Permit. Under previous permits, stormwater management systems were often one of the last site elements to be designed and were typically located typically at the end of pipe just prior to discharge from the site. Landscape based systems are different. They need to be considered earlier in the site design process so that they can be integrated into the landscape in a way that preserves their hydraulic functionality, water quality performance and aesthetic appeal. The hydraulic grade line is often a limiting factor for landscape-based systems which need to have runoff introduced at or near the surface. End of pipe biotreatment systems can be very challenging to design when influent is delivered by subsurface pipes without either backing water up into the drainage network or requiring plants that are far below the finished grade. Fortunately, these design challenges can be avoided by planning for biotreatment system location and design earlier in the site design process. This presentation will review innovative biofiltration case studies including a small-scale distributed approach gone well, an end of pipe approach with some sub-optimal hydraulics and aesthetics, and a large regional retrofit project which required special flow routing considerations. These case studies will illustrate practical project planning guidance that will help stormwater design engineers to avoid creating site constraints that force their stormwater treatment systems to operate poorly and/or look bad.

Fee-For-Service-Based Stormwater Management
Fee-For-Service-Based Stormwater Management
Storm water runoff compromises Hawaii’s supply of fresh water. In an effort to preserve our supply of fresh water, Hawaii’s State legislature passed Act42 (HB 1325), which authorizes its counties to adopt a stormwater utility form of funding and charge storm water fees. Through it, land owners pay a fee based on how much runoff leaves their property, and the fees will go toward maintaining the measures that prevent pollution. Through a university-industry-local government collaboration facilitated by TRUE and Transform Hawaii Government, a prototype solution was developed to enable land owners to understand their storm water runoff financial obligations both before and after they make improvements to their facilities. Mentored by Belt Collins and DataHouse, students from UH College of Engineering & Waipahu High School delivered a prototype solution that will fundamentally enable the establishment of “fee-for-service-based” funding of a community’s defined stormwater management program.

Stormwater Parks - Meeting the nexus of community and water quality needs
Stormwater Parks - Meeting the nexus of community and water quality needs
Public utilities are ever more challenged with not only addressing water quality and level of service needs of their ratepayers but to also address community and equity needs where feasible. A growing international trend is to develop stormwater parks where open space is co-developed to provide open space and manage stormwater. This presentation will provide a summary of the motivation, examples, and implementation challenges for developing stormwater parks. Ranging from hidden stormwater functions that allow for more active community uses, to parks that feature the stormwater function and education, to floodable spaces that provide increased resilience, a range of stormwater options exist that can effectively integrate with and enhance community benefits. The presentation includes examples from the Pacific Northwest, Southern CA, Missouri, Miami, Atlanta, Philadelphia and Syracuse.
