Jared Tetzlaff MacLachlan [] [+1-206-***-****]

I am a Geospatial analyst with fifteen years of experience, recently returned from Namibia where I was a trailing spouse without a work visa. I have particular expertise in linear routing, remote sensing, fluvial systems, environmental impact assessment, environmental remediation, and spatial statistics.

From classification of land use/land-cover to sighting of industrial-scale solar generation facilities, my work has consistently promoted the goals of sustainability, data-based decision-making and best professional practice. The range of my work has given me the capacity to analyze, create, and communicate spatial data in most any format known to the discipline. I seek a position consistent with my experience and my belief in environmental stewardship. I am willing to relocate from Seattle WA and would happily accept travel or telecommute as well.

Selected Project Experience with Tetra Tech CES

Portland General Electric’s Cascade Crossing 4/2011-1/2014 This electric power transmission project would have resulted in significant forest clearing for maintained Rights-of-Way. In agreement with the US Forest Service, my colleagues and I designed and implemented a stream temperature monitoring program and collected data used in modeling potential effects of shade loss on stream temperature. I was a principal in this project from study design through field data collection, modeling, analyses to the final report. I performed all shade/temperature modeling key to the project using SSTEMP and HeatSource, which are specialized applications for this field. Other BLM and USFS contractors have cited this work in Environmental Impact Statements and other publications. I also conducted a synthetic streams analysis using LiDAR-derived Triangular Irregular Network (TIN) elevation data to correct stream alignments to refine road crossing risk assessments and have presented this new approach at professional conferences.

Developed new and original contributions to ROW clearing relationship to stream network disruption

Improved protocols used in stream temperature monitoring

Exposed critical flaws in accepted shade/stream temperature modeling

Puget Sound Energy Energize Eastside 1/2013-2/2017 This 230 kV transmission line is planned to connect substations ~ 13 km distant, through densely populated suburban and urban areas in Washington State. The client anticipated significant public opposition to the project. My project manager and I were able to offer the client an objective, reproducible and transparent set of GIS analyses that determined optimal project routes based on client-defined spatial constraints and opportunities. I was responsible for all linear routing analyses, route segment alternative evaluation and impacts analyses as well as follow-on studies required by public comment and regulatory action. Further tasked to perform quality control on LiDAR data acquired by another contractor, my review revealed critical errors in classification and return-order of which the client was unaware, saving great expense.

Demonstrated an objective and documentable approach to the complex decisions governing the location of a linear project; expertise in this area equaled by fewer than fifty professionals in the area

As technical lead and primary client interface, supervised five supporting analysts on a major project

Confederated Tribes, Umatilla Reservation Geomorphic Assessment, Walla Walla R. 6/2016-4/2017 This effort was pursuant to ongoing aquatic habitat improvements on ~44 Km of the channel and floodplain. I created a coherent bare-earth and channel elevation model integrating SONAR, waterborne LiDAR and airborne IfSAR point-clouds for this project. This task was particularly challenging due to the LiDAR data including no return-order information and the of density of the vegetation involved. Using Q-Coherent LP360 and ArcGIS processing tools, I constructed a composite dataset suitable for engineering and design.

Developed original methods for data integration, improving data quality and saving significant cost

NextEra Energy Critical Issues Analysis 11/2013-4/2014 I was tasked by the client with screening over sixty candidate wind-farm sites for critical issues and fatal flaws on a highly accelerated schedule. I implemented automation steps for the production of a large volume of maps required for field visits and final reports. I also managed staffing and analysis of national datasets, streamlining project work-flow and contributing to

standardization of screening results and on-time completion of the screening.

Coordinated a company-wide team of analysts and developed practical methods for streamlining cartographic production and rapid data compilation


MA, Geography, GIS, Georgia State University, 2005

Thesis: An exploration of the relationships among basin morphometery, area and common to extreme flood magnitudes using GIS and statistical modeling. My research into the geomorphic determinants of a range peak flow magnitudes using DEM-derived channel network and basin characteristics and flood data from 30 drainages in the Appalachian and Piedmont regions of the U.S. required compilation, cleaning and analysis of (DEM) data covering ~15,000 km . My work resulted in a new algorithm improving the fidelity of drainage

networks derived from DEMs (synthetic streams) and in a set of multiple regression analysis models capable of predicting up to 95% of observed peak flow variance. These models were rigorously validated using principal components analysis, making them applicable throughout those geomorphic regions.
