These City staff members led us on tours through Weowna Park, Kelsey Creek Park, and Lake Hills Greenbelt Park to stimulate our thinking about how the City could mitigate the effects of climate change through strategic maintenance and redesign of its parks.We especially want to thank Brian Landau, Utilities Planning Manager, and Jennifer Ewing, Environmental Stewardship Program Manager, for their continued feedback and guidance about our project’s scope of work. Thank you both for joining us on our field trips to the aforementioned parks and for sharing your knowledge about the role and value of Bellevue’s parks.

    Hydrogeologic Framework and Numerical Simulation of Groundwater Flow in Bellevue, Washington

    Hydrogeologic Framework and Numerical Simulation of Groundwater Flow in Bellevue, Washington James Bush A report prepared in partial fulfillment of the requirements for the degree of Master of Science Earth and Space Sciences: Applied Geosciences University of Washington May 2017 Project Mentor: Jonathan Turk, Brown and Caldwell Internship coordinator: Kathy Troost Reading committee: Juliet Crider J. Michael Brown MESSAGe Technical Report Number: 054 Hydrogeologic Framework and Numerical Simulation of Groundwater Flow in Bellevue, Washington ©Copyright 2017 James Bush 1 Hydrogeologic Framework and Numerical Simulation of Groundwater Flow in Bellevue, Washington Abstract Though the city of Bellevue, Washington is the fifth-most populous and fourth-fastest growing community in Washington, groundwater studies encompassing the city are noticeably few. Population growth, urban development, and recent drought have highlighted the need for a more detailed and comprehensive under- standing of Bellevue’s groundwater system. In response, this study developed a conceptual hydrogeologic model and numerical groundwater flow model of Bellevue and its immediate vicinity to provide a basic understanding of the groundwater flow system. The numerical model was implemented in MODFLOW-NWT, and focuses on the unconsolidated sediments present in the study area. The study area covers the Bellevue city limits and adjacent areas between Lake Sammamish and Lake Washington. Simulation of the groundwater flow system indicates that precipitation falling on the study area is the only significant source of recharge to the unconsolidated sediments. Approximately half of all recharge enters the groundwater system directly, while the other half runs off into surface water bodies before leaking into the groundwater system. All kettle lakes in the study area lose water to the groundwater system under steady state conditions.

    Chapter 6 Current Conditions

    STORM AND SURFACE WATER SYSTEM PLAN January 2016 CHAPTER 6 CURRENT CONDITIONS - STATE OF THE STORM AND SURFACE WATER SYSTEM This chapter describes the state of the natural and constructed storm and surface water system as it exists in the first decade of the 21st century. Existing or baseline conditions of the storm and surface water system are described and used to evaluate the system that forms the basis of the Storm and Surface Water Basin Plan recommendations. This chapter is organized into three major categories 1) Flood Protection, 2) Water Quality Protection, and 3) Fish and Wildlife Habitat. Storm and Surface Water System Plan recommendations are based on analyses of each of these categories. Existing Conditions of the Storm and Surface Water System Background The City of Bellevue is part of the larger Puget Sound drainage basin. Located in the Lake Washington/Cedar/Sammamish Water Resource Inventory Area, stormwater originating in Bellevue either drains to Lake Sammamish east of the city or Lake Washington to the west. Lake Sammamish itself is a tributary to Lake Washington via the Sammamish River. Lake Washington drains to the Puget Sound via the Lake Washington Ship Canal (Ship Canal) at Montlake, then to Lake Union, and eventually through the Hiram M. Chittenden Locks (Ballard Locks) in Seattle to the Puget Sound. The storm and surface water system in Bellevue consists of a Historic logging in western Washington created series of open streams, a network of pipes, long-term impacts to streams and watersheds. storage facilities, lakes, ponds, wetlands, collection, and treatment facilities all in a mix of public and private ownership.
