Principal Engineering Geologist, QISP, QSP/QSD, CESCL
With more than 20 years of experience as an Engineering Geologist, Ms. Nancarrow’s expertise lies in the management of environmental monitoring programs, groundwater and stormwater treatment for heavy metals, technical expert litigation support, NPDES permit compliance, and the implementation of comprehensive environmental programs in industrial facilities. She has experience in the remediation of heavy metals and hexavalent chromium of similar large, complex, multi-party, high-profile RCRA sites under the direction and regulatory authority of the US EPA, various state agencies including WA Ecology, CA DTSC, CA RWQCB, AZ DEQ, as well as tribal and local municipalities. Ms. Nancarrow has experience with forensic geochemical fingerprinting of chromium isotopes and all phases of active remediation projects including site investigation, characterization of the nature and extent of contamination, remedial strategy feasibility evaluation, pilot testing, system construction, start-up, O&M, and optimization. Her remediation experience was utilized as a Project Manager for the Department of Ecology’s multiyear NPDES Inspection Sampling Support Project, where over 40 facilities contributing to the Lower Duwamish Superfund Site were inspected and sampled. Ms. Nancarrow has co-authored 3 technical papers regarding in-situ remediation of heavy metals in groundwater, and she has received 3 Exceptional Performance Awards from her prior work on the Boeing Remediation Program in Southern California. She has served as a committee member on several EPA ITRC teams, including the Sediment Remediation team and the Mine Water Treatment team. Most recently, she served on their Stormwater BMP Performance Evaluation Team (check out their guidance information here), whose work included the creation of a tool to help regulatory agencies and design engineers chose the best stormwater treatment options available (learn more about the ITRC’s BMP Screening Tool here). When Christine isn't busy working or chasing her toddler around, she dabbles in building a wooden kayak and spends time plotting her next international adventure.

Heidi’s 14 years of project design oversight and quality control experience includes the management, design, and construction of stormwater infrastructure projects throughout Washington and Michigan. She has performed engineering design for stormwater improvements including stormwater conveyance calculations, sizing of stormwater detention, retention, and dry well systems. Additional design experience includes stormwater pipe sizing, including allowable discharge rates based on location specifications. Heidi has also performed engineering design related to site civil grading for various types of land development projects including temporary erosion and sediment control design and construction. Beyond stormwater design and engineering, Heidi has provided Quality Assurance/Quality Control for several types of construction projects for government agencies including the Army Corps of Engineers, Naval Facilities Engineering Command, and the Strategic Systems Program. In her spare time, Heidi enjoys making cupcakes, watching sports, and dreaming of fast cars.

Mary is a civil engineer with 8 years of experience in water resources and stormwater engineering. She has designed many river restoration and stormwater projects to abate flooding, prevent erosion, protect infrastructure, improve water quality, and enhance riverine and estuary habitat for the success of salmon and other native species. Typical project components include bank stabilization, Large Woody Debris (LWD) structures, culvert replacement, flood plain reconnection, estuary habitat enhancement, tide gate replacement, flood conveyance, and temporary and permanent erosion control Best Management Practices (BMPs) and monitoring. She has designed projects for a variety of clients including Native American tribes, private industries, and regional and federal government agencies. Working in partnership with other engineering disciplines, scientists, technical experts, construction contractors, and governmental regulators, she has prepared construction bid-ready documents (plans, specifications, and cost estimates) and overseen construction. Further, she has performed engineering analyses, calculations, and hydraulic modeling. Mary’s passion for restoring and protecting the environment goes beyond the workplace. A long-time EarthCorps supporter and participant, Mary offers homestay to young people participating in their leadership training program. Mary, her husband, and three boys love to get outside and enjoy what the Northwest has to offer, and they love to spend the weekends camping, mountain biking, paddling, and swimming.
Frances is a Civil Engineer with 4 years of experience in residential land development. Her design work includes two large multi-phase single-family subdivisions in San Antonio as well as several individual single-family residences in the Puget Sound. Her subdivision design experience has primarily focused on water and sewer line sizing and alignments, stormwater collection, routing and detention, as well as street sections, right-of-way, and alignments for local and arterial roads. Complementing this work, she has prepared Construction Stormwater Pollution Prevention Plans, Erosion and Sediment Control Plans, lighting plans, signage plans, fire protection plans and assisted in underground utility locating. Her favorite parts of working at Pacific Stormwater are the flexible schedule and the focus on purpose driven design. Frances is a member of the Society of Women Engineers and Engineers Without Borders and takes every opportunity to learn and advance in her profession. When she doesn’t have her engineering cap on, she is busy taking care of her four children, two cats and two dogs in Tacoma, WA.
