  Citation × Citation Citation Abstract Copy Title: Holgate Lake Study: An Examination of the Issues Associated with Groundwater Flooding Author: Lynch, John J., Jr., Mader, Heidi A., McCann, Mark Year: 1999 This project examines Holgate Lake. Despite its natural hazard characteristics, the Holgate Lake area has not been immune to development pressure. Holgate Lake is an intermittent water body that forms when groundwater levels rise. Historical accounts show that the lake has formed at many different times in the last century. Because the lake fluctuates with the groundwater level, it is not necessarily present from year to year. As the area has developed, more and more people built in the location of the natural lakebed when the water was not present. When the lake level returned in the 1960's flooding of homes in the area became a significant concern. The water remained for up to three months at a time, causing people to leave their homes and belongings behind. A period of dry weather persisted through the 1970's and 1980's, which lowered the level of concern about the lake's potential impacts. Due in part to the lower level 0 concern, development continued to occur in the area. However, the concerns returned in 1996 and 1997 when the lake level rose and inundated the area. These events refocused the City of Portland's attention on this area and its flooding issues.

  Citation × Citation Citation Abstract Copy Title: Gateway Gardens Site Analysis Author: Gage, Chris, Renfro, Rory, Sarver, Jessica, Sturtz, Ben, Wolters, Nicole Year: 2006 The Gateway Gardens Site Analysis takes a comprehensive look at a largely-vacant land area in Portland’s Gateway District. Currently owned by the Oregon Department of Transportation (ODOT), the 38-acre site currently serves as right-of-way for surrounding freeways, namely Interstates 84 and 205. The project team developed a sequential process for completing this report. To gain an understanding of the project site, the initial step consisted of identifying key historical events and land uses that formed the site into what it is today. The team then conducted an in-depth existing conditions analysis, covering a wide range of elements including natural and man-made characteristics, current uses and management. This analysis also identifies the project site’s location within the context of other relevant planning efforts. Based on the existing conditions evaluation, the project team developed a series of potential land use elements. The text identifies specific assumptions regarding each element, including land ownership, access provisions, estimated cost and other key variables. The list of uses was developed under the assumption that several elements could potentially co-exist with one another, and that several land use combinations are possible. It should be noted that this report does not present specific recommendations for the project site; rather it is intended to acquaint readers with the site as it exists today, and to identify the feasibility of various land uses. The project’s next step should include a more-detailed evaluation of the potential land use elements along with coordination among relevant agencies and the public to move those uses forward.
