2019 CEID On-Street Parking Assessment 2

I. Introduction

This summary presents initial findings of the 2019 Central Eastside Industrial District annual data collection effort. This year’s data is contrasted, where applicable, to findings gathered in 2018. Methodologies for collecting data were identical for each of the two survey years; including cataloguing hourly license plate data for all parking stalls in the designated study area over a 12-hour study day and cataloguing all permit use (by displayed permit) over the same period. The 2019 survey was conducted on Thursday, April 11, 2019. The 2018 survey was conducted on Wednesday, April 3, 2018.1

II. Surveyed Parking Inventory

Per the recommendation of the Central Eastside Transportation and Parking Advisory Committee (TPAC) the 2019 parking survey data collection day and routes were adjusted from 2018. The intent of the TPAC for these alterations is to ensure that new areas of the district are routinely sampled, and seasonal variations are accounted for; creating a more robust data base for analysis and greater district representation. Figure A, next page, displays the selected 2019 study area (shaded in dark blue) and overlays the 2018 study area block faces (red lines).

General ConsiderationBecause data for 2018 and 2019 were collected in the spring, comparative analysis will be consistent as to time of year, even with amended data zones selected by PBOT and the TPAC. Data from 2017 and 2018 was collected in fall and spring, respectively, as a means to evaluate seasonal differences (which were evident for overall peak hour occupancy). The ability to view these types of comparative findings is instructive and establishes a more representative view of the parking dynamics in the district as well as insights into specific areas and issues important to PBOT and the TPAC.

1 In 2018, 2,224 stalls were sampled versus 1,911 in 2019. This difference is simply a function of the data zones selected by the City and the CEID TPAC for analysis.

Key 2019 Outcomes• Peak hour shifted to 12:00 PM in 2019 from 11:00 AM in 2018.• Peak hour occupancy increased from 77.9% in 2018 to 88.6% in 2019.• Significant increase (10.6%) in average hourly occupancies in all surveyed hours.• “Or By Permit” stalls 95.0% occupied in 2019 versus 86.1% in 2018.• In 2019, 2,689 permits displayed in peak hour versus 3,021 in 2018, extrapolated.• Violation rate in 2019 is 25%, down from 31% in 2018.• Recommended decrease in 2019 permit allocations to 0.60 FTE (from 0.63).• Potential conflicts between visitors and employees competing for access to stalls is growing.

III. Inventory

Figures B1 through B6 provide a detailed breakout of the 2019 surveyed inventory with comparison to 2018.

• 2019 sampled 1,911 stalls; 363 fewer stalls than in 2018’s 2,274 stalls.• The use type most affected by the decrease in stalls surveyed were No Limit stalls; decreasing from 220 in

2018 to 73 in 2019. Also, the number of 30-minute stalls surveyed dropped from 122 in 2018 to 75 in 2019. • 2 Hour stalls comprise 91% of the studied area in 2019 (1,737 stalls). Of this total, 449 are metered, 232 are

signed 2 Hours only and 1,056 are designated 2 Hours Or By Permit.

IV. Occupancy

Figure C identifies differences in hourly parking occupancies between the two study years. Figure D on the following page provides a block-face level “heat map” view of the peak hour (12:00 PM – 1:00 PM) for the entire sampled study area.

• The 2019 peak hour shifted to 12:00 PM versus 11:00 AM in 2018. • The 2019 peak hour occupancy was 88.6% as compared to 77.9% in 2018. This is a significant increase but

may be reflective of the dynamics of the reconfigured data collection zones.• 2019 occupancy levels are higher than 2018 occupancies in all 12 hours surveyed. The average hourly

increase is 10.6 percentage points.• As in 2018, overall use of the on-street supply declines in each hour after 1:00 PM.

2019 CEID On-Street Parking Assessment 9

Key findings include:

• Peak hour occupancies in 2019 for all stalls (88.6%) are up 10.7 percentage points compared with 2018 (77.9%).

• Overall violation rates are down by 5.7 percentage points to 24.8%. • The average length of stay for a user of a 2 Hour Metered stall is 1 hour and 50 minutes, with a violation rate

of 16.3%. The average length of stay for a 2 Hour Signed stalls is 2 hours and 49 minutes, with a violation rate of 35%. This is a pattern that is consistent with 2018 data findings for this stall type and illustrates a compliance efficiency inherent to metered stalls.

• The average length of stay for a user (without a permit) in a 2 Hour Or By Permit stall exceeds 3 hours, with violation rates of 33%.

• 2 Hours Or By Permit stalls (Zones G & N) have peak hour occupancy rates in excess of 94% (essentially fully maximized). This is higher than the average peak occupancy for the district (88.6%).

• Every unique stall type signed 2 Hours or greater has peak occupancies well in excess of 85%; an indicator of significant constraint. Only 15/30 Minute, ADA Accessible and 2 Hour metered stalls have peak occupancies under 85%.

Tables 2A & B provide a summary of key metrics by type of user (all, non-permit and permit) across a number of utilization metrics. Additional comparisons between the two study years are made on the following page, as appropriate.

Page 10: Central Eastside Industrial District PARKING ASSESSMENT ... · occupancy, empty stalls, average length of stay and violation rate. The table displays comparative results of the 2018

2019 CEID On-Street Parking Assessment 10

Key findings include:

• In 2019, 4,546 vehicle trips were recorded. This is an increase of 1,003 vehicles (or 28%) as compared to 2018 (3,543). Of this total, 3,544 (78%) were non-permit trips (e.g., visitors). In 2018, 2,495 of 3,543 vehicles (70%) were non-permit vehicles. This growth in percentage indicates the increased presence of visitors in the district, especially given that the overall number of stalls surveyed was (363) less in 2019 versus 2018.

• There were 1,002 vehicles with permits observed parking in the on-street supply in 2019 within the surveyed data zone – a decrease of just 46 permits from the 1,048 observed in 2018.1 As with the increase in visitor trips, this is interesting given that the total number of “Or By Permit” stalls sampled decreased from 1,289 (2018) to 1,056 (2019); with use of permits staying very stable between the two years.

• 228 vehicles (not displaying a permit) were observed moving between stalls over the course of the study day. In 2018, 152 vehicles were observed. Said another way, 6.4% of cars parked are moving their vehicles around the parking district, possibly to avoid a citation, or possibly because they had business in another part of the CEID.

• The rate of stall turnover increased 24%, from 2.33 (2018) to 2.90 (2019). This is likely due to the significant increase in visitor vehicles observed in 2019 (variability of the sampled study area). The rate is still low by industry standards (5.0 is considered “efficient”), but not unexpected in an industrial area with a high number of employee permits in use.

Tables 3A-E summarize utilization metrics only for stalls that allow a 2 Hour time limit (Signed, Metered, and Or By Permit). These include peak occupancy, user group, vehicle trips, vehicle hours parked, average length of stay and turnover rate.

• Of all the 2 Hour stall types, only 2 Hour Metered stalls have an average time stay less than 2 hours (1 hour and 51 minutes) for non-permit users.

• 2 Hour Metered stalls turnover at 5.33. When permit users are taken out of the average, turnover in these stalls increases to 5.46. This is a favorable rate of turnover complementary of the industry standard for turnover in visitor areas (minimum target rate of 5.0).

• 2 Hour Metered stalls maintain peak occupancy of 76.7%; well within PBOT and TPAC’s target range for efficiency.

• 2 Hour Signed stalls are 89.7% occupied in the peak hour, with 203 vehicles parked. Of this total, 21 users are vehicles with permits (not allowed to park in these stalls). These stalls are highly constrained by industry standards and use by permit holders may be caused by the fact that Or By Permit stalls (in Zones G and N) are even more constrained (over 92%).

• 523 vehicles are parked at the peak hour in 2 Hour Or By Permit stalls (Zone G), a 95.8% occupancy. Of this total, 140 vehicles (27%) are Non-Permit Users (i.e., visitors). This indicates meaningful demand for access into these areas by visitors who are competing with permit users for space in this constrained stall type.

• 449 vehicles are parked at the peak hour in 2 Hour Or By Permit stalls (Zone N), a 94.1% occupancy. Of this total, 173 vehicles (39%) are Non-Permit Users (i.e., visitors), up from 26% in 2018. As in Zone G, high permit use (plus occupancies significantly over 85%) in these stalls may be in conflict with visitor needs.

Overall, utilization rates for 2019 show a continuing trend of constraint within the district. It appears vehicle trips to the district have increased, particularly in visitor trips. This has contributed to peak hour occupancies significantly in excess of the 85% occupancy target established for the district. Given the constraints, potential conflicts between visitors and employees competing for access to stalls is growing.

1 It should be noted 1,002 trips (with permits displayed) are simply those observed within the sampled study sample. This number will be statistically extrapolated to the entire OBP inventory during upcoming discussions of future permit allocations with the City and the TPAC.

VI. Permit Activity

Table 4 illustrates permit activity by hour of day as well as shows the peak hours for each permit type (highlighted in gray).

• The peak hour for permit use occurs at 11:00 AM, when 732 permits are displayed in the surveyed supply. At this hour, a total of 1,603 vehicles are parked, with 723 permits displayed (or 45.7% all vehicles parked).

• In 2018, the peak hour was the same, and 53.6% of vehicles parked in the peak were displaying permits.

Figure E provides an hourly breakout of displayed permits by permit type.

• Across all hours of the day both Zone G and Zone N permits are relatively constant in the percentages of permits observed, ranging from as little as 44% to as high as 51%. This is in contrast to 2018 results which showed nearly two-thirds of permits were Zone G, with only one-third came from Zone N. This anomaly may simply be the result of a shifted sample study area.

• Use of carshare “permits” increases as a percentage of all permits between 5:00 and 7:00 PM.• Temporary permits have a slightly higher percentage of the overall total both at 7:00 AM and at 6:00 PM.

Figure F illustrates the hourly distribution of all users (non-permit/permit) over the course of the survey day.

• There is a great deal of variability in the number of permits in use over the course of the day.• The bulk of users displaying permits were observed between the hours of 9:00 AM (664) and 3:00 PM (600);

in each case making up between 49% and 42% of all occupied stalls.• The number of non-permit users stays fairly consistent between 10:00 AM (808 vehicles) and 4:00 PM (885

vehicles), with a midday (1:00 PM) peak reaching 943 users. • Beginning at 5:00 PM, when the majority of permit users have left for the day, the number of non-permit

users (visitors) spikes, reaching nearly 1,000 at 5:00 PM and over 1,100 by 6:00 PM. This is further evidence that the district is in flux, particularly after standard work hours – likely due to an emerging food/bar scene.

VII. Permit AllocationTable 5 provides an accounting of the number of permits the City allocates by zone. As the table indicates, 2019 allocations are defined by two Zones (G & N). In 2019, Zone G permits decreased 8% from 2018 levels; interestingly Zone N permits increased by 8%, which is in contrast to the intended attrition of these permits over time.

Table 6 illustrates the basis for estimating current number of stalls by use based upon the sample surveyed. The estimates are based on 2019 findings extrapolated to a larger CEID supply area totaling 6,925 stalls (row 1, column C).

As the table shows there are differences in the 2018 and 2019 sample sizes and the distribution of stalls types. The comparison between the two sample years (rows 1 – 5, columns A and D). Note the 2018 sample heavily skews toward Zone G (1,029 stalls) versus Zone N (278); the 2019 sample is much more balanced, 557 stall in Zone G and 499 stalls in Zone N.

The purpose of this assessment is to establish a measured breakout of the current supply, tracking where permit users are parking, by type of stall, and using that information to extrapolate the findings to the entire inventory. A complete inventory of the CEID parking district was conducted in early 2018, so the extrapolation of permit use to the entire area should be very accurate (Table 6B).

• There are a total of 3,855 stalls within the entire inventory of stalls where parking with a permit is allowed (Table 6a - the sum of rows 3 and 4, column C). This represents about 56% of all parking in the district. The remaining 3,070 stalls (44%) do not allow parking with a permit (row 5, column C), their purpose to exclusively serve visitor access.

• 2019 findings indicate there are 694 permits displayed in the sampled supply during the peak hour (Table 7 - row 4, column A). Of this total 383 are parked in Zone G and 276 in Zone N (rows 1 and 2, column A). These vehicles are parked in valid OBP stalls (where we want them to be).

• An additional 35 permits were observed in other stall types, where permits are not allowed (Table 7 - row 3, column A).

• When these 694 permits are extrapolated to the entire parking supply, there are 2,689 permits displayed during the peak hour on a “typical” day (Table 6b - row 4, column C). In 2018, 2,857 permits were displayed at the peak hour (Table 8 - row 4, column D).1

A CEID goal is to maintain occupancies in all stalls at 84%, as a means to ensure system efficiency and provide flexibility to accommodate seasonal demand variations and future growth.

1 Note rows 6 - 8, column C, extrapolate permit use for each permit zone and non-permit area.

Table 7 summarizes the number of Zone G and N permits that would be allocated to support efforts to lower occupancies in 2 Hour OBP stalls from a current rate of 98% to 84%.

Key findings from table include:

• The actual “peak occupancy” rate is 98% if the 35 (137 extrapolated) current permits improperly using non-permitted stalls were to be directed to 2 Hour OBP stalls (row 2, column A.)

• Currently, 6,483 permits are allocated to businesses in Zones G and N (sum of rows 3 and 4, column A). The current allocation of permits to businesses is based on 70% FTE.

• Of this total, 4,563 (71%) are allocated to Zone G (row 3, column A). The remaining 1,867 (29%) are allocated to Zone N (row 4, column A).

• By comparison, in 2018, 4,969 permits were allocated to Zone G (rows 3 and 4, column B) and 1,726 permits to Zone N.

• Float for each zone is very high, ranging from 213% in Zone G to 456% in Zone N (rows 5 and 6, column A). • Based on current peak hour occupancies, 926 permits would need to be reduced from current allocations to

bring occupancies in OBP stalls to 84% (row 8, column A). • To support this finding, the City would need to limit (cap) the total number of permits allocated to 5,557 (row

9, column A). This would be about 500 less than was recommended in 2018 (row 9, column B).• If successful, it is estimated that 2,305 permits would be parked in the peak hour in 2020 (row 10, column A)

versus the 2,689 permits currently shown in the extrapolated model (row 7, column A).• The FTE allocation model would need to be reduced to 60% (row 11, column A) versus the current 70%

(rows 3 and 4, column A).

2019 CEID On-Street Parking Assessment 18

Table 8 below, illustrates the distribution of permits by zone based on the recommended cap total (5,500).

• If the City capped the number of allocated permits at 5,500 and distributed them based on current distribution percentages for Zone G (71%) and Zone N (29%), Zone G would be limited to 3,905 permits, Zone N to 1,595 permits.

Impact of Zone N Elimination on Permit AllocationIf and when Zone N is eliminated it will have an additional impact on permit distribution in Zone G stalls. Currently there is a 63-permit differential in the number of G Zone permits parking in N Zone stalls (108 Zone G are parked in N and 171 Zone N are parked in Zone G). When those additional permits are added into the Zone G 2 Hour OBP stalls; it raises the peak hour occupancy to 104% (versus 98% in the Table 8, Row 7 calculation. This increases the number of permits that need to be reduced to achieve an 84% occupancy level, from 926 to 1,247. To achieve this reduction (if Zone N is eliminated) will require an FTE level of 0.57.

VIII. Summary and Next Steps

Overall, hourly occupancies in the district have increased since the 2018 survey of the area, at an average of 10.6 percentage points. Some of this may be attributable to the different profile of sampled stalls in the study area – 2019 was more balanced between Zone G and Zone N stalls, whereas the 2018 study skewed toward Zone G by a 3:1 ratio. The use of Or By Permit (OBP) stalls remains highly constrained at levels significantly over 85%. Some adjustments in permit allocations are necessary to bring occupancy levels in OBP to stated goal levels of 84% - in the range of an FTE allocation of 0.60 versus the current 0.70. This will ensure an effective balance between permit use and visitor need.

It is clear more visitor trips are occurring in the Central Eastside throughout the workday, but particularly after 5:00 PM. It is anticipated this trend will continue, while adequate on-street parking capacity exists in the evening hours as employees head home, demand for that capacity is on the rise which may eventually trigger a need for greater parking management in the later hours (e.g., extended enforcement hours).

Violation rates decreased between 2018 and 2019, from 31% to 25%. Violation rates in metered stalls are the lowest of all stall types because of the compliance efficiency found in metered stalls. It appears that some reformatting will also need to be evaluated as 1 Hour stalls and No Limit stalls still remain in the district. No Limit stalls may aid in accommodating the 137 permits parked in stalls not designated for permit use.

Discussing the recommended parking permit allocations, expanded meter coverage, and opportunities to reformat stalls is the obvious next step after review of these findings with PBOT and the CEID-TPAC.
