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 kiddo around, she dabbles in building a wooden kayak and spends time plotting her next international adventure.
Principal Civil Engineer, PE
Heidi’s 15 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.

Typical project components incorporated detailed hydraulic modeling, including model maintenance, model build and verification, solution modeling/optioneering; DG5 investigations, spill analysis, sewer rehabilitation and condition assessment, river modeling, options appraisal, flood risk assessment and flood mapping. Tintu is proficient in the use of Integrated Catchment Modeling (ICM), WWHM, SWMM, InfoWorks CS, InfoNet, Flood Modeler, TUFLOW, Microdrainage, MapInfo, ArcGIS, QGIS and Vertical mapper. On the weekend, Tintu enjoys exploring the Pacific Northwest with her husband and young son.
Civil Engineer, CESCL
Frances is a Civil Engineer with 5 years of experience in land development. Her design work includes large, multi-phase, single-family subdivisions, multiple single-family residences in the Puget Sound, commerical sites, as well as industrial facilities. Fran’s experience has primarily focused on water, sewer, and drainage line sizing and alignments, stormwater collection, routing and detention, as well as street sections, right-of-way, and alignments for local and arterial roadways. 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 including the pursuit of her Low Impact Design Certificate from Washington State University. 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.
