Engineer I
April 2016 to Present
Hydraulic and hydrologic modeling using SBUH, Regression Equations, the Rational Method, SWMM, HY-8, HEC-RAS, and MGSFlood. Storm water analysis and design using the Snohomish County Drainage Manual. Preliminary cost estimation and design using Civil 3D in support of infrastructure projects and drainage investigations. Writing Hydraulic Reports. LID retrofit analysis and project proposals in support of surface water quality improvement projects.

Hydraulic Modeling for 106th PL SE and Woods Lake Road in Monroe, WA.

1. Used surface flows from an HSPF model to develop a SWMM hydraulic model of a combined drainage ditch, culvert and storm pipe network experiencing yearly flooding events.
2. Validated model results using data collected during a February 2017 storm event.
3. Completed a Hydraulic Summary Report documenting the existing system, the modeling process and results, including flooding recurrence intervals and erosion locations.
4. Developed and modeled system updates to eliminate flooding at the 25-year recurrence interval.

LID Retrofit Proposal for the Snohomish County Water Quality Facilities Strategic Plan.

1. Used County GIS data, LIDAR imagery and existing County infrastructure to identify and score priority catchments with a high need for water quality treatment and flow control.
2. Developed an LID retrofit analysis, project proposal and cost estimate for LID retrofit projects, including permeable pavement, bioretention cells and bioswales.
3. Directed another engineer in the project proposal, including directing and reviewing design proposal.

Hydraulic Modeling for Roosevelt Road in Monroe, WA.

1. Used surface flows from an HSPF model to develop a SWMM hydraulic model of a combined drainage ditch and culvert network experiencing yearly flooding events.
2. Validated model results using data collected during a February 2017 storm event.
3. Wrote a Hydraulic Summary Report documenting the existing system, the modeling process and model results, including flooding recurrence intervals and erosion locations.

Hydrologic and Hydraulic Modeling of culverts discharging to Harvey Creek and Jim Creek in Arlington, WA.

1. Used LIDAR, GIS hydrologic processing tools such as ArcHydro, and data gathered from field investigations to develop a watershed basin and surface flow network upstream of two culverts with documented flooding problems.
2. Used USGS regression equations and the SBUH method to develop peak runoff flows for each basin.
3. Used HY-8 to develop a hydraulic model of both culverts to determine potential solutions to flooding problems.
4. Both culverts were assessed for fish passage status and the proposed replacements were designed to meet fish passage requirements.
5. Developed a design proposal in Civil 3D to eliminate flooding at the 25-year recurrence interval.

2. Analyzed and designed LID technologies, including permeable pavement and bioretention facilities in MGSFlood and WWHM.
3. Designed the storm water, water and wastewater networks for the site using Civil 3D.
4. Developed final construction plans and cost estimates for all elements of the project.

BNSF Bridge Replacement Project in Skagit County

1. Calculated project Threshold Discharge Areas and completed a downstream impact analysis to determine the applicable minimum requirements in SWMMWW 2012.
2. Wrote a Hydraulic Report documenting the design process and applicable requirements.
3. Calculated surface water runoff flows and determined catch basin inlet spacing and storm water network sizing using WSDOT Excel Spreadsheets.
4. Designed the storm water network, storm water wetvault and bioswale in Civil 3D to meet the SWMMWW 2012 requirements triggered by the project.
5. Analyzed utility conflicts and coordinated relocation of water, wastewater and telecommunication utilities in the project area.
6. Developed final construction plans and cost estimates for all elements of the project.
