From Stormwater Monitoring to Adaptive Management: Getting the Most Out of a Permit-Driven Effectiveness Evaluation

Andy Weigel

Brown and Caldwell, United States of America;

Solutions for reducing pollutant loads in urban stormwater runoff are almost never a one-size-fits-all proposition. Advances in design of Green Stormwater Infrastructure, proprietary treatment systems, and innovative policy strategies have grown at an exciting pace in recent years. With a wealth of solutions, it can be difficult for public entities managing stormwater infrastructure to collect and analyze the various data and information needed to make sound decisions when selecting solutions for specific stormwater management needs. Monitoring data collected for permit compliance alone may not be adequate to answer these questions.

The Ada County Highway District (ACHD) is the lead agency for the only Phase I MS4 Permit in Idaho. ACHD shares permit compliance and stormwater management responsibilities with five other permittees to cover a 58,000-acre permit area that includes the cities of Boise and Garden City. In 2017 ACHD completed an intensive two-year data collection effort in a small residential subwatershed draining to an infiltration best management practice (BMP). Monitoring and modelling results were used to evaluate the effectiveness of this widely used BMP.

The evaluation included:

• Continuous flow and rain monitoring covering 55 rain events;

• Flow-weighted composite water quality sample collection for 6 rain events;

• Modelling of BMP pollutant removal, source loads, and stormwater runoff volume using the Source Loading and Management Model for Windows (WinSLAMM); and

• event-based qualitative observations.

The presentation will provide information on how the results of this evaluation are being used to refine runoff volume and pollutant loading estimates for larger, more complicated, subwatersheds throughout the permit area, and inform updates to BMP design guidance. The presentation also includes a discussion of how the results of this effectiveness evaluation and other permit-driven studies and evaluations are being used to guide the next phases of data collection and planning efforts to achieve higher pollutant load reductions in urban stormwater runoff.

Merging Stormwater and Safety Opportunities; When Forces Unite

Nick McMurtrey1, Kaaren Hofmann2

1Murraysmith, United States of America; 2City of Newberg, Yamhill County, Oregon, United States of America; ,

Despite the building boom underway in the Pacific Northwest, stress prevails within the capital budgets available to municipal agencies. Resource demands from regulatory requirements, a saturated bid climate, active community members, right-of-way encroachments, and franchise utility conflicts all compete for infrastructure improvement funding.

The City of Newberg commenced a corridor safety upgrade in 2015 on a prominent collector route. Upgrades involved improving multi-modal safety through introduction of bike lanes, sidewalks, lighting, enhanced pedestrian crossings, and speed appropriate geometric roadway design. During the process, Murraysmith and the City identified multiple synergetic opportunities along the way to incorporate stormwater management, fish passage upgrades, right-of-way acquisition and utility undergrounding while managing a deficit in CIP funding.

This presentation will help attendees:

1. Identify stormwater opportunities for projects considering similar safety improvements

2. Provide budgeting assumptions for stormwater improvements relative to existing CIP’s and master plans

3. Inform public involvement campaigns to show rate payers tangible results

4. Review construction options available for rapid assembly fish passage structures

Brief Biography and/or Qualifications
Nick McMurtrey, P.E., has Bachelor of Science in Civil Engineering from Oregon State University. Nick has worked as an engineering consultant for 15 years, serving a variety of planning, design and construction roles on transportation and water projects for municipal clients.

Kaaren Hofmann, PE has a Bachelor of Science in Engineering from Saint Martin’s University. Kaaren has worked in municipal government for 22 years, the last 3 as the City Engineer in Newberg.

Creative Community Engagement Improves Stormwater Outcomes

Elizabeth Spaulding1, Emiline Hogg2

1The Langdon Group; 2City of Nampa Environmental Compliance Division; ,

It takes an entire community to meet the challenges of reducing pollutants in stormwater. Individual behavior changes can have a significant impact on what pollutants end up down the drain, and public education on stormwater issues can drastically improve water quality outcomes.

The City of Nampa Environmental Compliance Division’s Stormwater Outreach Program has been recognized as a leader in engaging the public to meet its stormwater objectives. The program strives to improve local waterways by providing education and outreach about the benefits of clean water, with a special focus on underserved populations. Not only do these efforts improve water quality outcomes, they empower the local community members and strengthen the relationship between the city and its citizens.

This presentation will highlight the variety of activities that the City of Nampa’s Stormwater Outreach Program has implemented since 2010, including:

• Community Clean Up Days

• Nampa School District Partnership

• Nampa Stormwater Advisory Group

• City Acres Park Stormwater Kiosk

• Stormwater Summer Camp

• Bilingual Educational Material

This presentation will also address the importance of engaging underserved populations, and speak to the City’s approach for ensuring the interests and needs of these populations are incorporated into the outreach programming.

Brief Biography and/or Qualifications
Elizabeth Spaulding is a project manager and facilitator with The Langdon Group. She has extensive experience supporting local, state and federal agencies in engaging the public to address complex environment and natural resource issues across the west. Elizabeth has provided public outreach support to the City of Nampa’s Stormwater Outreach Program since 2016.


Emiline Hogg is the Public Outreach Coordinator for the City of Nampa’s Environmental Compliance Division. Prior to joining the City in 2015, she worked as an educator for the Nampa School District.
