Project Ideas

Residential Infill Project Rezoning and Permits: Analyze the impact of Portland's Residential Infill Project and Oregon House Bill 2001 on building permits in Portland. Look at the number and type of permits issued before and after the adoption of RIP, and examine the location and size of properties where permits are issued to understand the effects of these changes on the housing market.

Permit Issuance and Valuation Prediction: Model the predicted change in home value resulting from a permit being issued for a specific property. Use historical permit data and property features, such as location, size, and zoning, to train the model.

ADU Impact on Home Value: Investigate the effect of Accessory Dwelling Units (ADUs) on home values in Portland. Look at the number of ADU permits issued over time, and compare the home values of properties with and without ADUs.

Permit Issuance Trends Over Time: Identify trends in permit issuance over time, including changes in the number and type of permits issued each year, as well as differences across neighborhoods or property types.

The amount of floor area in relation to the amount offsite area, expressed in square feet. For example, a floor area ratio of 2 to 1means two square feet of floor area for every one square foot of site area. FAR is different based on zoning, and works with maximum height to control the overall bulk of buildings. See Zoning Code chapter 500 for details. https://www.portlandoregon.gov/bps/34563-- Additional Information: Category: Zoning Code Purpose: To regulate the amount of use on a site.

The basis for these features is U.S. Geological Survey Scientific Investigation Report 2017-5024 Flood Inundation Mapping Data for Johnson Creek near Sycamore, Oregon. The domain of the HEC-RAS hydraulic model is a 12.9 mile reach of Johnson Creek from just upstream of SE 174th Avenue in Portland, Oregon to its confluence with the Willamette River. Some of the hydraulics used in the model were taken from Federal Emergency Management Agency, 2010, Flood Insurance Study, City of Portland, Oregon, Multnomah, Clackamas and Washington Counties, Volume 1 of 3, November 26, 2010. The Digital Elevation Model (DEM) utilized for the project was developed from LiDAR data flown in 2015 and provided by the Oregon Department of Geology and Mineral Industries. Bridge decks are generally removed from DEMs as standard practice. Therefore, these features may be shown as inundated when they are not. Judgement should be used when estimating the usefulness of a bridge during flood flow. Comparing the bridge to the surrounding ground can be more informative in this respect than simply looking at the bridge itself. Two model plans were used in the creation of the flood layers. The first is a stable model plan using unsteady flow in which the maximum streamflow is held in place for a long period of time (a number of days) in order to replicate a steady model using an unsteady plan. The stable model plan produced the areas of uncertainty contained in the sycor_breach.shp shapefile. The second is an unstable model plan that uses unsteady flow in which the full hydrograph (rising and falling limb) is represented based on the hydrograph shape of the December 2015 peak annual flood. The unstable model plan produced the flood extent polygons contained in the sycor.shp shapefile and the depth rasters and represents the best estimate of flood inundation for the given streamflow at U.S. Geological Survey streamgage 14211500.

Portland's business districts and neighorhoods inherently support each other in many ways. Since 1986 Venture Portland has invested in the smart, strategic growth of Portland’s unique neighborhood business districts. These dynamic districts, which together make up a majority of the city’s businesses and nearly half of its jobs, play a vital role in Portland’s economic prosperity and collectively represent local, regional, national and international demand for goods and services.-- Additional Information: Category: Boundary Purpose: For mapping and analysis of business districts in Portland.

Benchmarks are survey markers that provide a point of particular elevation used as a reference for determining elevations of other points in a survey. They are used by surveyors, engineers, planners, and contractors for establishing elevations for planning, designing, and/or construction of various projects.The City of Portland is responsible for establishing and maintaining a network of benchmarks throughout the city, each having a known elevation expressed in feet in the City of Portland’s own datum (established in 1896). Most of the City of Portland’s Benchmarks are brass disks about 2 ½" in diameter, and all are marked "City of Portland Bench Mark No. nnnn " and usually set in the curbs of streets. Occasionally you’ll see larger disks of 3 ¾" diameter which are "Class A" monuments, and some benchmarks are set in retaining walls, bridge wing walls, culvert headwalls, concrete steps, or wherever the most stable and accessible placement was determined to be for a specific location. You might also see benchmarks similar to those of the City of Portland’s but with another governmental agency’s or private firm’s name stamped on it. Occasionally the City of Portland Benchmark Book will refer to these monuments and provide elevations, but more often you’ll have to contact the appropriate institution for more information. The benchmark numbers the City assigned to outside agency monuments are for indexing purposes only; PDOT does not stamp a City of Portland benchmark number on other agencies' monuments.-- Additional Information: Category: Survey Purpose: For mapping and analysis related to the maintenance of survey benchmarks.
