1 Introduction The purpose of this Transportation Management Plan (TMP) for the Interstate (I) 205 from Stafford Road to Oregon Route (OR) 213 project (the Project) design segment is to provide the details regarding the development of Traffic Control Plans (TCP) and other measures recommended during the construction phase of this project. During construction, it is desired that disruptions and delays to travelers and freight be minimized without compromising public or worker safety and the quality of the work being performed. This TMP is considered a living document and will be subject to additions and modifications throughout the design life of this project.

2 Project Area Boundaries The section of I-205 from Stafford Road (beginning at milepoint [MP] 2.9) to just beyond OR 99E (MP 9.6) is the last remaining segment of two-lane freeway on the I-205 corridor, resulting in congestion and crashes. Insufficient capacity, as well as the closely spaced Interchanges (OR 43, OR 99E, and OR 213) and the current OR 43 northbound (NB) entrance ramp configuration, results in significant I-205 travel delays in both the morning (a.m.) and evening (p.m.) peak periods. Collectively, these conditions contribute to safety and travel-time predictability issues, which result in significant delays to passenger and freight traffic. Regional growth is also expected to expand the congested peak periods, further reducing the number of hours vehicles can move on the system without major delay.

The Project area is provided in Figure 1. I-205 is an Oregon Department of Transportation owned and maintained facility within the City of West Linn and City of Oregon City limits. Adjacent land uses are a high-density mix of commercial and residential developments. The Project area is in ODOT Region 1 in Clackamas County.

2.1 Proposed Improvements The proposed improvements have been clearly defined and identified in the project charter. Details of the proposed Project are provided below:

• Add a third I-205 through lane NB and southbound (SB) from Stafford Road (MP 2.9) to OR 99E (MP 9.6).

• Reconstruct the I-205 SB auxiliary lane from the OR 99E exit ramp to the OR 43 entrance ramp (across the Abernethy Bridge)

• Reconstruct and extend the I-205 NB auxiliary lane from OR 43 entrance ramp to OR 99E exit ramp (across the Abernethy Bridge)

• Construct the NB auxiliary lane from the OR 99E entrance ramp to the OR 213 exit ramp.

• Adjust the OR 99E Interchange ramp geometries to conform to the additional freeway lanes.


2 | May 7, 2018

• Modify the OR 43 Interchange by consolidating the entrance and exit ramps and removing the existing OR 43 NB entrance ramp that connects to the Abernethy Bridge.

• Remove the portion of the rock slope adjacent to the I-205 NB direction to support the freeway widening.

• Add active traffic management (ATM) elements throughout the Project limits, consistent with the ODOT Region 1 ATM Project Atlas (published April 2016).

• Replace or widen and seismically retrofit the bridges throughout the corridor that are shown in Figure 1.

2.1.1 Construction Bundling Strategy As part of the Cost-to-Complete Report [HDR 2018], the Project Team evaluated the most cost effective approach to construction packaging and alternative bidding. As a result of that evaluation, the Project Team recommends that the Project be constructed using three separately phased construction contracts, or "packages", as follows:

• Package A: Northern Package (Abernethy Bridge plus adjacent Interchanges). Package A consists of the Abernethy Bridge widening and retrofit, the OR 43 and OR 99E Interchange reconstructions on either end of the bridge, the widening and retrofit of the Main Street Bridge, and the construction of a new I-205 NB auxiliary lane from OR 99E to OR 213.

• Package B: Southern Package (I-205 Widening) Package B consists of the I-205 widening from Stafford Road to the Abernethy Bridge. It also includes the rock cut required to widen the roadway between Sunset Avenue and OR 43, the West A Street and Sunset Avenue bridge replacements, the Broadway Street Bridge removal, and the replacement or widening and retrofit of all bridges carrying I-205 from 10th Street to Stafford Road.

• Package C: ATM Package C consists of the ATM improvements throughout the Project limits, except those attached to the Sunset Avenue Bridge (which will be constructed as an element within Package B).

2.2 TMP Goals The primary purpose of this TMP is to address the construction-related traffic impacts of this Project in a cost-effective and timely manner with minimal interference to the traveling public and adjacent properties. To accomplish this goal, the TMP incorporates the following elements:

• Project area characteristics

• Identification of other projects in the area that will require coordination

• List of holidays, local events, or seasonal restrictions

• Factors impacting traffic control and construction staging plans

• Mobility

• Pedestrian and bicycle connectivity and mobility through the work zone

• Business hours of operation and access needs

• Proposed construction staging

• Lane closure restrictions

• Rolling slowdown activities

• Limited duration road closures

• Traffic management and operational strategies


May 7, 2018 | 5

• Incident management plan

• Public information and communication plan

2.3 Safety A common deficiency noted by internal annual ODOT work zone reviews are design and accommodation measures used for managing bicycles, pedestrians, and Americans with Disabilities Act (ADA) users in the work zone. An emphasis will be made on this Project with advance plans to develop work zone friendly bicycle and pedestrian TCP plans.

Potential work zone safety strategies which could be employed as the design progresses further include:

• Provide law enforcement in the work zone

• Construct pads for enforcement parking within the construction zone

• Implement a temporary speed reduction order during construction

• Implement a smart work zone system

In addition, the ATM system, including variable message signs (VMS), variable advisory speed signs (VAS), and queue warning signs, that will be installed with Package C will be utilized to enhance work zone safety and provide real-time communication to the traveling public during construction of Package A and B. The Project team may also look to unique strategies, such as “on-call” towing for breakdowns due to the limited shoulder width.

2.4 Data Analysis Existing year traffic volumes for the study area were developed for the a.m. and p.m. peak hours using the I-205 mainline counts collected in May 2017. Traffic volumes were balanced between intersections and along I-205. The existing average daily traffic volume (ADT) on I-205 in both directions ranges from approximately 90,000 to 119,000 vehicles per day.1 Crash data will be added with 60 percent submittal.

3 Project Area Characteristics The following section includes a summary of existing transportation conditions within the Project area relevant to this TMP, includes traffic and roadway characteristics, and Project stakeholders.

3.1 Traffic Characteristics The majority of traffic on the corridor is made up of passenger vehicles and small trucks. Because this corridor serves many of Oregon City and Clackamas industrial areas, the impact of delays on freight and the cost to providing goods and services are also

1 2016 AADT from ODOT Transportation Volume Tables published in November 2017


6 | May 7, 2018

concerns. I-205 has the second highest freight volume in the region, ranging from 7,900 to 13,100 trucks per day.

3.2 Roadway Characteristics According to the 1999 Oregon Highway Plan, I-205 is classified as an Interstate Freeway and a designated Freight Route and Truck Route on the National Highway System (NHS). Within the Project area, I-205 is primarily a four-lane facility with major junctions at I-5, OR 43, OR 99E, and OR 213.

OR 99E is classified as an Urban Principal Arterial and is part of the NHS system. It is identified as an “Orange Route” on the Motor Carrier Transportation Division (MCTD) Freight Mobility map, which identifies OR 99E as a high route, as well as a reduction review route.

OR 43 is classified as an Urban Principal Arterial and is part of the NHS system. It is identified as a “Black and Yellow Route” on the MCTD Freight Mobility map, which is viewed as a “highly restricted” route.

3.3 Location of Other Construction Projects To minimize impacts for traffic traveling through the Project area on I-205 and surrounding roadways, it is critical that this Project be coordinated with other projects planned in the area. Opportunities should be explored to schedule projects during different time periods or stage them to avoid overlapping impacts to traffic.

Other projects currently shown in the Statewide Transportation Improvement Program (STIP) in this area include:

• OR 43: Multimodal Transportation Project

• OR 99E: Clackamas River Bridge

• I-205 at OR 43 Illumination

• I-205: Abernethy Bridge – SE 82nd Drive

3.4 Project Stakeholders There may be times during Project construction when it will become necessary to contact stakeholders in the area to inform them of updated project developments, such as schedule updates, traffic control modifications, or major potential disruptions. Primary stakeholders within the Project area include major road authorities, emergency service providers, government contacts, garbage collection, mail service, local shopping centers, and local utilities.

Local emergency service providers will be notified of the expected lane closures on I-205 to ensure that emergency services are able to reach all locations in the Project area during construction. The contractor should meet with the emergency service providers prior to the beginning of construction in order to confirm expectations for emergency services and to coordinate communications. A list of Project stakeholders is provided in Table 1.

o Use a rolling slowdown method (RSM) for slowing traffic and closing all traffic lanes on the East Portland Freeway (I-205) for periods not to exceed 20 minutes while erecting bridge girders and erecting sign structures. This work will be allowed only between 11:00 p.m. and 5:00 a.m.

o Provide written notification to the Engineer and all affected emergency services at least 14 days before using the RSM. Calculate the location where the pilot cars will begin the RSM and the speed at which the pilot cars will travel to accommodate the needed time to complete the work within 20 minutes.


12 | May 7, 2018

o Perform a RSM as shown on the supplemental drawings. Use one pilot car for each lane to be slowed. Use only pilot cars to control the flow of traffic on the freeway. Use one additional pilot car as a chase vehicle to follow the last free-flowing vehicle ahead of the blockade. The pilot cars shall enter the roadway at the posted speed, form a moving blockade, and slowly reduce traffic speeds to create a gap in traffic to accomplish the work without completely stopping traffic.

o Place a portable changeable message signs (PCMS) a minimum of ½-mile in advance of the start of the rolling slowdown. Place flagger(s), and appropriate devices and signing, at the terminal of all closed entrance ramps within the controlled delay area. Establish and utilize radio communications to adjust the speed of the blockade, as necessary. Maintain radio communications at all times among the pilot cars, flaggers, and the construction crew.

o Begin work immediately after the chase vehicle has passed the work area. If work is not completed when the pilot cars approach the work area, immediately cease all work except what is necessary to clear and reopen the roadway to traffic. Allow traffic to clear before performing another RSM.

4.2 Package A: Northern Package (Abernethy Bridge) Description

Figure 2. Package A – Work Limits

4.2.1 General Information Package A begins at MP 8.75 south of the Abernethy Bridge and extends to the easterly end of the Project (MP 10.25). This package generally consists of the Abernethy Bridge widening and retrofit, the OR 43 and OR 99E Interchange improvements, the Main Street Bridge widening and retrofit, and the construction of the NB auxiliary lane extension from OR 99E to OR 213 (Figure 2).

Package A’s attributes include:


May 7, 2018 | 13

• The existing Abernethy Bridge consists of two general-purpose lanes in each direction, an existing auxiliary lane in each direction between OR 43 and OR 99E, a nominal six-foot left median, and right shoulders in each direction. Package A widens the Abernethy Bridge structure to add a third general purpose lane and maintain the auxiliary lanes between OR 43 and OR 99E. The package also improves the existing six-foot right shoulder to a proposed 10-foot-width, which meets the standard width for an auxiliary lane. The Project will maintain the existing six-foot median shoulder width that does not meet the standard median shoulder width for a three-lane freeway.

• Package A will reconfigure the OR 43 Interchange to consolidate the entrance and exit ramps into a single location (Figure 3).

Figure 3. OR 43 Interchange with Proposed Roundabout

• Package A connects the OR 99E Interchange ramps with the widened Abernethy Bridge (Figure 4). The added third mainline travel lanes are carried through the OR 99E Interchange and ties into the three lanes north of OR 99E. No work is included to increase capacity on the ramps; therefore, no ramp widening is included other than to meet geometric standards. Ramp meter locations will be adjusted during Final Design if there is an advantage to do so. The Project does not include any improvements on OR 99E; therefore the ramp terminals will remain in their existing locations on OR 99E. The Project will construct a retaining wall between the OR 99E NB exit ramp and Main Street to eliminate impacts to Main Street or existing right-of-way.

May 7, 2018 | 15

• Package A will upgrade both the Abernethy Bridge and Main Avenue Bridge to meet current seismic design standards.

4.2.2 Maintenance of Traffic Package A will require limited duration road closures, RSMs, and lane closures to accomplish the work. Due to high traffic volumes and the limited availability of suitable detours, these measures will only be allowed during the time periods provided in Section 4.1.

00220.42 Bridge Site Road Closure

• Close the East Portland Freeway (I-205) to traffic at the bridge site during transverse launch of the Abernethy Bridge. Do not close the road until all materials and equipment are on hand or guaranteed to be delivered so that the work can be done in an efficient manner with a minimum period of road closure.

• The road closure will not be allowed until the area and the detour route are signed according to the TCP and the requirements of Section 00225.

00220.70 Opening Sections to Traffic

• The Contractor will be permitted to take the northbound I-205 entrance slip ramp out of service when the northbound East Portland Freeway (I-205) has three (3) or more lanes from the northbound I-205 entrance loop ramp to the northbound I-205 exit ramp to Pacific Highway East (OR 99E).

• Refer to the traffic control summary sheet (EA01) for a simplified explanation of the anticipated road closures.

4.3 Package B: Southern Package (I-205 Freeway Widening) Description

Figure 6. Package B – Work Limits


16 | May 7, 2018

4.3.1 General Information Package B begins at MP 2.83, just south of the Stafford Road Interchange entrance and exit ramps, and continues to MP 8.75, just south of the Abernethy Bridge (Figure 6). This package generally consists of the I-205 freeway widening from Stafford Road to the Abernethy Bridge, upgrading freeway signing, performing rock cut required to widen the freeway between Sunset Avenue to OR 43, replacing and/or widening and retrofitting all bridges that carry I-205 or conflict with the proposed rock cut, and adding a small retaining wall.

Package B’s attributes include:

• The Package B freeway centerline alignment meanders slightly compared to the existing alignment.

• I-205 freeway widening (western Project limit start to 10th Street) – This freeway section experiences recurring congestion in each direction, particularly in the NB direction where three travel lanes are reduced to two travel lanes near the Stafford Road Interchange. The extension of the third travel lane is anticipated to eliminate this recurring congestion.

• I-205 freeway widening (10th Street to Abernethy Bridge) – The area between the 10th Street Interchange and the Sunset Avenue overcrossing will transition from the inside widening, which occurs from Stafford Road to 10th Street, to widening entirely towards the Willamette River just prior to the Sunset Avenue overcrossing. The south side widening will extend to the Abernethy Bridge section where the proposed 12-foot median shoulders will transition back to match the existing median shoulder width of 6 feet on the Abernethy Bridge.

4.3.2 Roadway Improvements Within the limits of Package B, the Project widens I-205 by slightly altering the freeway centerline alignment and widening in the directions shown in Table 2.

The Project will establish 12-foot outside shoulders for I-205 throughout the Package B limits to maintain a safe space in the event of vehicular breakdowns (Figure 7).

Figure 7. Rendering of a Typical Example of Future Roadway Improvements

The Project will generally maintain the existing freeway geometry with only slight alterations with the exception of the NB travel way near the Borland and Tualatin Bridges where the alignment was relocated toward the existing median to improve staging and lower construction costs and impacts. Other modifications include raising the highway profile by 9 inches to construct a continuously reinforced concrete pavement (CRCP) overlay section.


18 | May 7, 2018

4.3.3 Rock Cut Excavation and Containment The area beginning approximately 1,000 feet south of Sunset Avenue and continuing to OR 43 includes existing, nearly vertical rock slopes. The existing rock slopes were constructed with a fallout area approximately 24-feet-wide extending beyond the edge pavement. The rock slopes were excavated on slope angles of approximately 4V to 1H. During the 2006-2007 I-5 to Stafford Road widening project, rock scaling was performed within this area (Figure 8).

Rock slope angles of 4H to 1V, similar to the existing cut slopes in this section, are proposed. The Project Team proposes a 10-foot containment area for rock heights less than 40 feet, transitioning to a 20-foot containment area for rock heights of up to 70 feet, both with a concrete shoulder barrier as additional mitigation for potential rock rollout. The proposed alignment does not affect or improve the northern rock face.

4.3.4 Maintenance of Traffic Package B will require limited duration road closures, rolling slowdowns, and lane closures to accomplish the work. Due to high traffic volumes and the limited availability of suitable detours, these measures will only be allowed during the time periods provided below:

00220.40(h) Road Closure Using Rolling Slowdown Method for Blasting

• Use a RSM for slowing traffic and closing all Traffic Lanes on the East Portland Freeway (I-205) for periods not to exceed 20 minutes while blasting. This work will only be allowed a maximum of 30 times, when shown, or directed during the following dates and periods of time except as indicated in 00220.40(e)(2):

o Monday morning through Friday night between 10:00 a.m. and 1:00 p.m.

o Saturday morning through Sunday night between 9:00 a.m. and 10:00 a.m.

• Rolling slowdown closure for blasting will be allowed only after September 1, 2021 and before May 31, 2022.

• Provide written notification to the Engineer and all affected emergency services at least 14 days before using the RSM. Calculate the location where the pilot cars will begin the RSM and the speed at which the pilot cars will travel to accommodate the needed time to complete the work within 20 minutes.

Figure 8. View of an Existing Project Rock Cut Area


May 7, 2018 | 19

• Perform a RSM in accordance with ODOT Standard Detail No. DET4740. Use one pilot car for each lane to be slowed. Use only pilot cars to control the flow of traffic on the freeway. Use one additional pilot car as a chase vehicle to follow the last free-flowing vehicle ahead of the blockade. The pilot cars shall enter the roadway at the posted speed, form a moving blockade, and slowly reduce traffic speeds to create a gap in traffic to accomplish the work without completely stopping traffic.

• Place a PCMS a minimum of ½ mile in advance of the start of the rolling slowdown. Place flagger(s), and appropriate devices and signing, at the terminal of all closed entrance ramps within the controlled delay area. Establish and utilize radio communications to adjust the speed of the blockade, as necessary. Maintain radio communications at all times among the pilot cars, flaggers, and the construction crew.

• Begin work immediately after the chase vehicle has passed the work area. If work is not completed when the pilot cars approach the work area, immediately cease all work except what is necessary to clear and reopen the roadway to traffic. Allow traffic to clear before performing another RSM.

• Refer to the traffic control summary sheet (EA01) for a simplified explanation of the anticipated road closures. Alternative strategies for avoiding the Stafford Road Interchange ramp closures, 10th Street Interchange ramp closures, and Oswego Highway (OR 43) Interchange closures with additional temporary roadways will be evaluated as the design progresses.

4.4 Package C: ATM Package Description Figure 9. Package C – Work Limits

4.4.1 General Information Package C includes ATM improvements throughout the Project area, with the exception of the advisory signs mounted to the Sunset Avenue Bridge (which are constructed with Package B) (Figure 9). The Project’s ATM types are based on the 2016 ODOT Region 1 ATM Atlas. The ATM Atlas was developed without consideration for the proposed Project when determining ATM locations. The Project team has revised the proposed locations to take into


20 | May 7, 2018

consideration of the proposed widening. The recommended ATM locations, types, and structural supports within Package C are listed in Table 3 and Table 4.

Table 3. ATM Type and Location – NB Direction Location ATM Type Support type

MP 0.95 1 VMS signs; 3 VAS signs New sign bridge

MP 3.15 3 VAS Mount to existing Stafford Road Bridge overcrossing

MP 4.26 1 VMS New sign bridge (over NB lanes only)

7.60 1 VMS and 3 VAS Three VAS NB and Type 1.5 VMS NB

MP 8.26 1 VMS and 3 VAS New sign bridge (over NB and SB lanes)

Table 4. ATM Type and Location – SB Direction Location ATM Type Support type

MP 8.26 1 VMS and 3 VAS New sign bridge (over NB and SB lanes)

MP 10.18 3 VAS New sign bridge structure

MP 11.68 Replace existing VMS Existing sign bridge

The ATM improvements include VAS and VMS. The NB queue warning VMS east of Stafford Road Interchange (MP 4.1) provides queuing warnings near the 10th Street Interchange. The NB VMS north of 10th Street provides queuing warnings near the OR 43 Interchange area. The SB VMS north of OR 213 at MP 11.7 provides queuing warnings near the OR 99E Interchange. The combination of VMS and queue warning VMS is expected to improve travel time reliability and reduce crashes caused by queuing. The VAS signs at approximately MP 8.4 (as part of Package B) completes the NB and SB operational segments and provides additional benefits for crash reduction.

Because Package C will be constructed before any other Project work, the ATM system will provide real-time communications to the traveling public during construction of Packages A and B (such as the example in Figure 10).

Figure 10. Example of VMS within Project


May 7, 2018 | 21

4.4.2 Maintenance of Traffic Package C assumes all proposed ATM features will be constructed without daytime lane closures. For some of the sign structure installation and sign mounting, 20-minute rolling slowdowns or nighttime lane restrictions may be utilized as described in the all packages section of the lane closure restrictions in section 4.1.

4.5 Holidays and Special Events Traffic within the project area can be impacted by holidays and local special events. Nighttime lane or ramp closures will not be allowed during holidays or special event days. The major holidays are included as standard restrictions in the construction specifications. Local special events that may create an increased burden on the project area.

Major holidays are included as standard restrictions in the construction specifications. The additional restricted work dates for this project that will be included in the 00220.40(e)(2)(b) boilerplate special provision are:

• West Linn Holiday Parade • New Year’s Day • Memorial Day • Independence Day • Labor Day • Thanksgiving Day • Christmas Day

4.6 Existing Vehicle Restrictions I-205 is a designated freight and oversize/overweight route, generally, as defined by the ODOT Motor Carrier Transportation Division (MCTD). There are no existing weight, height, or width restrictions for vehicles within the project area.

For work on OR 43 and OR 99E (both freight routes), OR 43 is a black and yellow “highly restricted” route and OR 99E is an orange over dimension route.

4.7 Environmental Issues Environmental issues are not anticipated to impact construction staging or project scheduling. Erosion control measures will include inlet protection to filter stormwater runoff and compost socks around excavated areas to prevent sediment from leaving the project area and to meet current standards.

4.8 Seasonal Restrictions Some construction activities, such as paving or pavement marking installation, require relatively dry and warmer conditions. These activities typically occur during the summer months when traffic volumes are at their highest levels that generally require off-peak or nighttime work.


22 | May 7, 2018

Vegetation removal will be required for this project, and the Migratory Bird Treaty Act prohibits this activity during the March 1 to September 1 breeding season unless nest clearance surveys are conducted.

4.9 Construction Noise Regulations The project corridor is a mix of residential and commercial land usages. The City of Oregon City permits a maximum construction noise standard (85 dBA at a 50-foot distance) from 7 a.m. to 6 p.m. Monday through Friday and from 9 a.m. to 6 p.m. Saturday. The City of West Linn permits a maximum construction noise standard from 7 a.m. to 7 p.m., Monday through Friday and from 9 a.m. to 5 p.m. on Saturday and Sunday. Both Cities only permit minimal noise outside these hours. A construction noise variance will be required for this project and will be obtained from the Cities of Oregon City and West Linn. More information regarding the Cities of Oregon City and of West Linn construction noise regulations can be found in Appendix A.

We will have night work and weekend work. The areas of noise concern are the following:

• Weekend blasting for Rock removal between Sunset Ave and OR 43.

• Night and weekend bridge demolition and construction work

• Various locations of night time and weekend work for freeway widening (corridor wide)

• Night or weekend ramp closures and lane reductions at the OR 43 northbound entrance and OR 43 southbound exit ramps for bridge widening and bridge paving.

Various locations of night time and weekend work on OR 43 for roadway reconstruction and utility work.

5 Mobility This section includes a discussion of vehicular traffic and bicycle/pedestrian mobility during construction, consideration of oversized vehicles, property access, input from the public and stakeholders, and agency coordination.

5.1 Traffic Mobility during Construction The construction phase of the project will include several types of closures ranging from portions of shoulders to single lane operation. To minimize traffic and freight mobility impacts, construction activities requiring lane closures on I-205 will be scheduled during nighttime hours as much as possible, as described in Section 4.1. As I-205 is a designated freight route, temporary traffic control and associated lane restrictions will be required to accommodate oversized vehicles during daylight hours (one half hour before sunrise to one half hour after sunset). Emergency vehicle access `must also be provided at all times. For work on OR 43 and OR 99E (both freight routes), OR 43 is a black and yellow “highly restricted” route and OR 99E is an orange over dimension route.


May 7, 2018 | 23

• Vertical clearance will be addressed around the OR 43 “up-and-over” route for both NB and SB freeway traffic. Final sequencing of the OR 43 Interchange reconfiguration and the removal of the Broadway Bridge will impact the ability for northbound over height loads and will be further investigated in later phases of design.

5.2 Consideration of Oversized Vehicles Over-dimensional vehicles can be anticipated during the following sunrise and sunset periods: • January: between 7:00 a.m. and 5:30 p.m. • February: between 6:30 a.m. and 6:00 p.m. • March: between 7:00 a.m. and 8:00 p.m. • April: between 6:00 a.m. and 8:30 p.m. • May: between 5:30 a.m. and 9:00 p.m. • June: between 5:00 a.m. and 9:30 p.m. • July: between 5:00 a.m. and 9:30 p.m. • August: between 5:30 a.m. and 9:00 p.m. • September: between 6:00 a.m. and 8:00 p.m. • October: between 7:00 a.m. and 7:00 p.m. • November: between 6:30 a.m. and 5:30 p.m. • December: between 7:00 a.m. and 5:00 p.m.

I-205 is an annual route that allows loads up to 14 feet wide during daylight hours without a permit. During times of anticipated over-dimensional vehicle presence, it is required to maintain a minimum usable roadway width on I-205 of 19 feet for a single lane. During nighttime hours, a minimum usable roadway width of 14 feet is required for a single lane. When maintaining two lanes of traffic, a minimum roadway width of 28 feet is required during daytime and nighttime hours.

MCTD requirements for freight restriction notification on state highways are as follows:

• No advance notification required – Minimum available horizontal clear distance is 19 feet for a single lane of traffic on I-205.

• Daylight Width Restrictions – Single Lane: Width restrictions resulting in a single lane of traffic during daylight hours require 35-day notification for a horizontal clear distance of less than 17 feet for I-205. Width restrictions between 17 and 22 feet for U.S. 26 require 14-day notification.

• Nighttime3 Width Restrictions – Single Lane: Width restrictions resulting in a single lane of traffic during nighttime hours require 35-day notification for a horizontal clear distance of less than 13 feet for I-205. Width restrictions between 13 and 22 feet require 14-day notification.

The minimum available horizontal clear distance is measured across the roadway between positive barriers, which can be a fixed object, channelization device, or concrete barrier. The contractor must notify MCTD, the ODOT Region Mobility Coordinator, and

3 Nighttime hours are defined as one half hour after sunset to one half hour before sunrise.


24 | May 7, 2018

the engineer, in writing, using Form #734-2357. The notification should include the reduced lane width or lowest dimension of vertical clearance for each stage, the anticipated duration and date of the restrictions, the approximate milepost location, and direction of travel affected. As soon as the restriction is lifted, notification must be sent to the same individuals on a revised copy of the original Form #734-2357 so this information can be relayed to all affected parties.

5.3 Bicycle/Pedestrian Mobility during Construction Bicycle and pedestrian mobility will be maintained throughout construction. Temporary bike lanes must be provided during daylight hours, when two lanes of traffic are open. There may be instances during nighttime lane closures where bikes will be required to use the roadway for short distances. Site-specific “Temporary Pedestrian Accessible Routes (TPARs)” and pedestrian-specific TCP will be provided to safely accommodate pedestrians during construction. Bicycle are “permitted” to use the shoulders of I-205 from I-5 to Abernethy Bridge. During construction, bicyclists will not be allowed on the shoulders of I-205. Bike lanes on OR 43 will be closed after the separated pathway is in place.

5.4 Transit Mobility TriMet bus routes will remain operational during construction, although bus stops within the project area may be relocated or closed temporarily. Add the following bullet to 00220.03(b) to address notification for temporary impacts to TriMet bus stops:

• Bus Stops – Notify TriMet a minimum of 21 calendar days in advance of closure or relocation as required in the plans.

• Contractor shall not impact consecutive bus stops at the same time.

5.5 Property Access Existing driveway access will be maintained or temporary accommodations will be provided for private property ingress/egress during construction. Garbage pickup, mail service, and other delivery vehicles (e.g., UPS, FedEx) will also need to be accommodated during construction. This information is provided for reference only. The Contractor shall work with the resident or business on a one-on-one basis to accommodate a window of time when the contractor may be allowed to temporarily close access. However, if no time exists, the contractor will be required to provide temporary access or stage constructed accesses half width at a time for businesses and residents fronting the corridor.

5.6 Input from the Public and Stakeholders The primary goal of the communications effort for this project is to inform project stakeholders and highway users of scheduled construction activities and expected impacts. ODOT Community Affairs staff will continue to coordinate with the public and project stakeholders throughout the design and construction process.


May 7, 2018 | 25

5.7 Agency Coordination Local agencies and other departments within ODOT will be contacted before beginning project construction to coordinate unknown issues not included in this document. Communication protocols are described in Section 8, and other known construction projects in the area are described in Section 3.3.

6 Proposed Construction Staging 6.1 Sequence of Work

The scheduled bid date for Package A is mid-2020, with construction of Package B continuing through mid-2023. Minimizing disruption and delays to the traveling public as well as accommodating for mobility is secondary only to safety in terms of the focus of the traffic management during construction.

6.2 Traffic Management Options for Bridge Launch 6.2.1 I-205 NB Closed

• I-205 NB Closed will require advanced notice of closure date

• It will also require advance signing of NB I-205 closure

• I-205 NB closed from I-5 to OR 99E

• Detour to I-5 and I-84

Alternative Access

• Access to OR 99E and OR 213 from south of Wilsonville

• Local destination access via I-5 interchanges

• Alternative ”local” detour using I-5 to OR 99E and OR 224 (Milwaukie Expressway)

Construction of Package A of the project can be accomplished in three stages, each with multiple phases. Construction of Package B of the project can be accomplished in seven stages, each with multiple phases. A general sequence of work is described below and may not be in this particular order:

6.2.3 Package A: Northern Package (Abernethy Bridge) Description

Construction Staging and Maintenance of Traffic

The assumed construction staging sequence and access and maintenance of traffic for this package is described below.

Abernethy Bridge (Construction Sequence) The Abernethy Bridge construction sequencing assumes that multiple bridge sections will be under construction simultaneously. Early work includes foundation improvements on the west approach spans, which will be accessed outside of the ordinary high water line. There are several key widening areas at existing gore points near the OR 43 NB entrance and OR 99E NB exit ramps. To access these areas, traffic will shift to the median shoulder. Weekend ramp closures may be required to access and complete closure pours required to accommodate later phases of work.

The majority of the first two construction seasons will focus on foundation improvements and substructure work. During the first in-water work season, the contractor will install temporary work bridges, which allows continued access to the foundations. As the approach structure foundations are completed, the contractor will widen the roadway to the outside with limited directional night or weekend lane reductions, or directional closures during girder placement and closure pour work.

The main span of the Abernethy Bridge will be widened using a technique of transversely shifting the existing box girders approximately 8-feet toward the outside, one direction at a time, under a weekend closure. This activity could be completed in as little as one night; however, weekend closures are currently proposed to accommodate any approach transitions or traffic control shifts that may be required prior to opening to traffic. After the transverse slide, the contractor will continue the cantilever widening (left and right shoulders) for each independent main span structure. Much of this work will be performed after traffic has been moved to the opposing shoulder.


30 | May 7, 2018

Abernethy Bridge (Construction Access) Gaining access to the bridge substructure and working beneath the bridge will be challenging. When the original bridge was built, no physical obstructions or traffic impeded construction activities. There was unlimited headroom for the large, tall equipment to construct the bridge (Figure 13). Now, however, the existing bridge, boat ramps, docks, parks, and the McLean House Park pose restrictions on construction access locations. (Figure 14).

Work platforms located on both sides of the bridge will access the main river span. The work bridge decks need to be 30- to 35-feet-wide to accommodate cranes and other large equipment. They will be elevated above the ordinary water surface to allow for the seasonal rises in the river. This only leaves 35 to 40 feet of headroom for large equipment.

Due to the access difficulties beneath the existing bridge to strengthen the existing substructure and foundations at Piers 3-6, these supports will be replaced with a “superbent.” The superbent consists of new drilled shaft foundations and columns located outside the edge of the deck of the widened bridge, along with a new bent cap that will span between the columns to support the bridge. The drilled shaft and columns will be located sufficiently away from the bridge to avoid the tapered steel pile foundations of the existing bents. Pier 3 is located adjacent to a boat ramp (an identified 6(f) resource) and Abernethy Creek, which feeds into the Willamette River next to the south column of this bent. Footing construction will impact the creek and will require it to be permanently diverted since the new replacement bent column lands within the creek.

c. 1968

Figure 13. Abernethy Bridge Construction


May 7, 2018 | 31

Figure 14. View of the Abernethy Bridge and Sportscraft Landing Park with Boat Ramp from the East Bank

Willamette River water levels vary significantly. The majority of foundation work will be performed from work bridges that will accommodate the fluctuation in river elevations. The Willamette River sees seasonal elevations that commonly reach between 25 and 29 feet. The contractor will maintain public access to the existing boat ramp and privately rented boat docks throughout construction. The Project Team is currently assuming the use of temporary work bridges constructed from both banks of the Willamette River. These temporary work bridges will be required to allow for boat traffic at the boat ramp and adjacent docks as well as mainline river traffic. Construction access options are still under investigation and will continue to be a primary focus as the foundation design solutions are refined.

Main Street Bridge

The Project will widen and seismically retrofit the Main Street Bridge. The median shoulders are not wide enough to accommodate traffic shifts needed for construction. Because of this, the selected seismic retrofit components are limited to those that can be constructed beneath the bridge. The widening work on the NB side of the bridge can be completed by shifting traffic toward the median with a temporary barrier on the right shoulder.

OR 43 Interchange

OR 43 construction sequence will be directly affected by the West A Street and Broadway Street construction activities. To minimize the duration of the temporary reduction in allowable high loads, the OR 43 ramp reconfiguration and removal of the Broadway Street Bridge will have interim completion dates. The temporary reduction in vertical clearance allows for the OR 43 widening and lane modifications, as well as the entrance loop reconstruction to occur before or with the work on the West A Street and Broadway Street structures. If a temporary reduction in vertical clearance for NB traffic is not permitted, sequencing alternatives may be considered that have other overlapping


32 | May 7, 2018

work or alternative local circulation options. Over-height loads will access the interchange ramps using the new roundabout.

The majority of the reconstruction of the OR 43 NB entrance ramp can be completed without impacting access to the existing ramp. Some of the work requires some weekend ramp closures to complete portions of the ramp that overlap with the existing loop ramp. Additionally, some weekend ramp closures may be required to reconstruct the proposed I-205 NB to OR 43 exit ramp.

OR 99E NB Exit Ramp The first 300 feet of the OR 99E exit ramp is located on the Abernethy Bridge. To keep the exit ramp open during construction, it will be temporarily relocated. The Project will shift the existing freeway travel lanes toward the existing median barrier to provide a work area for widening the southernmost approach span. This will accommodate a temporary loop exit ramp to carry traffic for the remaining widening and exit ramp reconstruction.

NB I-205 Auxiliary Lane Construction of I-205 NB auxiliary lane will widen the pavement to the outside. Traffic will be maintained by shifting lanes toward the median barrier. A temporary concrete barrier will separate the work area from traffic. A nighttime ramp closure is necessary to make the connection to the OR 213 exit ramp.

6.2.4 Package B: Southern Package (I-205 Freeway Widening) Description


There are generally two major independent work zones sections within the Package B work limits. These two areas and the assumed construction staging sequence for this package are described below.

Section between Stafford Road and South of Sunset Avenue This section of Package B is generally independent of any construction activities occurring within the Package A work limits. The roadway is a divided roadway with an existing median, and the assumption for traffic maintenance includes widening the existing roadway and utilizing temporary crossovers. The construction staging is anticipated to include the following stages:

• Stage 1 – Construct the widening and interim roadway improvements in the NB direction. This requires shifting NB traffic to the existing right shoulder, and then grading and partially constructing the new NB widening (to support traffic under stage 2). The NB-direction bridge widening and replacements will provide additional width to support temporary crossover traffic. Traffic will run at the existing roadway grade (e.g., no concrete overlays will have been constructed).

• Stage 2 – Using the crossovers, shift the SB traffic onto the widened roadway and structures completed in stage 1. This allows the contractor full access to the SB


May 7, 2018 | 33

roadway to complete all bridge and roadway work, including the final CRCP overlay over the existing travel lanes and shoulders.

• Stage 3 – Using the crossovers, shift traffic (in both the SB and NB directions) onto the newly widened SB travel lanes. Complete the NB CRCP overlay, construct the SB bridge replacements, and raise the widened / retrofitted bridges to their final elevation.

• Stage 4 – Relocate traffic (in both the SB and NB directions) into the final configuration, and remove any temporary facilities.

Section between Abernethy Bridge and South of Sunset Avenue Many factors, including the Sunset Avenue and West A Street overcrossing replacements sequence, the rock cut and pavement widening, and the freeway pavement rehabilitation, influence the construction staging sequence within this section. The construction sequencing and traffic staging of Package A also influences the construction sequence of this section. Based on a number of design requirements and considerations (i.e., vertical clearance, maintaining traffic, ease of construction, and staging between contractors), the Project Team developed the following conceptual construction sequence for this segment:

• Package A work (prior to beginning Package B work) – Complete the OR 43 improvements and the NB auxiliary lane extension between OR 43 and OR 99E.

• Package B overview – for work north of Sunset Avenue

o Construct Sunset Avenue and West A Street overcrossing replacements

o Perform rock cut via blasting and conventional ripping

o Perform freeway pavement rehabilitation and widening

This high-level strategy provides maximum contractor access with minimal traffic control stages. The existing Sunset Avenue, West A Street, and Broadway Street bridges act as traffic obstructions for the rock cut and pavement operations. Because of this, they will be reconstructed first. Once the existing structures are removed and their new columns are placed, there is a wider range of staging options available to maintain freeway operations.

To maintain local access, the Sunset Avenue replacement must be completed in phases. Initial work includes a partial demolition of the existing structure and a temporary freeway widening in order to accommodate traffic. Once the new overcrossing is built, Sunset Avenue traffic shifts onto the new structure and the existing bridge is removed. The removal of the existing bridge footing allows space to shift freeway traffic away from the rock cut area during rock blasting and removal operations.

West A Street Bridge will be reconstructed with traffic primarily detoured to OR 43 via McKillican Street, which has a signalized intersection with OR 43. A secondary local access detour route is via Broadway Street. During demolition activities, portions of the rock cut work will be concurrent with the bridge replacement work.

After the demolition of the existing overcrossings and successful rock slope removal, the remaining roadway rehabilitation will move forward. Traffic will be staged to construct the

roadway improvements in approximately one-third widths, maintaining two travel lanes in each direction. Interim OR 43 ramp connections are required and may necessitate a series of weekend closures.

6.2.5 Package C: ATM Package Description


The Project assumes all proposed ATM features will be constructed without daytime lane closures. For some of the sign structure installation and sign mounting, 20-minute rolling slowdowns or nighttime lane restrictions may be utilized.

6.3 Construction Traffic Control During construction, travelers can expect:

• Short-term lane, side street, shoulder, and sidewalk closures. Side street closures for up to 20 minutes during paving operations at intersections and street closures for signal pole erection are anticipated; both of which will occur at night.

• Allowable extended nighttime lane closures with single lane flagger controlled operation.

• Generally, one travel lane in each direction will be open to motorized traffic during daytime hours.

• Bicycles will be accommodated during construction. In general, a shoulder lane in each direction or a separated pathway will be provided. There are a few locations where limited duration shared bicycle/motorized vehicle lanes will be considered.


May 7, 2018 | 35

• Pedestrian routes meeting ADA requirements will provide access to adjacent properties during construction.

• Emergency vehicles and mobility will be accommodated throughout the project area during construction.

• Periodic closures of transit stops as allowed by TriMet. Transit will be accommodated throughout the project area during construction.

Strategies to reduce traffic demand within the project area include public information and outreach strategies, as well as the use of PCMS to alert drivers of ongoing and future construction activities. Detour routes will be further developed as the project’s final design progresses.

Public side street intersections and driveways will also be stage constructed under traffic, half width at a time with flagging as needed, if no alternate access is available. If alternate access is available, then public side streets will be closed to thru traffic allowing local access only.

Closure of consecutive transit stops in the same direction is not anticipated.

Providing the pedestrian portion of the shoulder will have priority over providing the bicycle portion of the shoulder. Pedestrians will be separated from motorized traffic with pavement markings where a separated pathway is not provided. Pedestrian channelizing devices will separate the non-motorized traffic from the adjacent parts of the work area closed to traffic. Motorized traffic will be separated from adjacent work areas closed to traffic with tubular markers. Cyclists will travel in the lane with motorized traffic when the bicycle portion of the shoulder is closed and a separated pathway is not available. When cyclists share the motorized vehicle lane, end of bike lane symbol (OBW1-9) and “Bikes on Roadway” signing will be provided.

Temporary driveways will be provided at critical locations to maintain continuous access (e.g., the Shell Station in the SW quadrant of the SE 122nd Avenue intersection). Accommodations for larger trucks and deliveries will be coordinated with landowners. Many parcels have multiple driveways that will allow for access throughout construction or driveways that can be constructed half at a time.

Site-specific “Temporary Pedestrian Accessible Routes (TPARs)” and pedestrian-specific TCP will safely accommodate pedestrians at intersections during construction.

7 Traffic Management and Operation Strategies To help meet the performance goals for congestion management and promote work zone safety, a range of traffic management strategies have been identified for consideration and implementation as described below.


36 | May 7, 2018

7.1 Public Information and Outreach Strategies Public information and outreach is essential for maintaining public support for projects, as well as encouraging changes in construction travel behavior. Informing the public of potential delays incurred while traveling through the project area or detour routes may encourage motorists to use alternate routes or plan trips to avoid peak construction activity times, which will help manage congestion within the project area. Strategies may include radio and television advisories, mailers, or the project website.

7.2 Motorist Information Providing motorists with real-time information helps notify drivers of upcoming work zones disruptions and may alleviate congestion and delay. Motorist information strategies may be used to provide traveler information in the following ways:

• PCMS: PCMS is a portable electronic sign that can display changeable messages. They are useful when informing drivers of upcoming construction periods and warning drivers of construction activities, as needed.

• Ground mounted signs: Typically installed at the endpoints of work zones informing motorists of road construction and the possibility of delay. Ground mounted signage would also be needed to alert motorists of Highway Advisory Radio information availability if/when provided.

• 511 (Highway Advisory Telephone): Inclusion of this project on ODOT’s statewide 511 highway advisory telephone system will help provide travelers with up-to-date information about construction activities and potential delays.

• Weekly Construction Report: ODOT produces a weekly construction report for the news media and an interested party’s mailing list. The content for this comes from the construction project manager to Region 1 Community Affairs staff for compilation and distribution. It also provides content for TripCheck.

• TripCheck (ODOT’s Intelligent Transportation Systems (ITS) website): TripCheck allows motorists to retrieve real time information and weather conditions via the Internet. Additionally, motorists may also call 511 to receive this same information.

7.3 Construction Strategies ODOT’s Guiding Principle Decision Tree Form was used in the development of the TCP is provided in Appendix B. The decision tree form helps identify separation options available for the work zone and captures impacts to safety, mobility, delay, driver and bicycle/pedestrian convenience, and other impacts when assessing traffic control options. It is anticipated the decision tree form and proposed construction staging will be updated throughout the design phase and captured in the TMP as the project progresses.

Potential construction strategies as they pertain to this project are described below.

• Temporary striping: When required, temporary striping on the travel lanes will be provided to direct and control traffic in areas where lane shifts are necessary.


May 7, 2018 | 37

• Planned closures: Temporary lane closures, when required, will be limited to off-peak and nighttime hours. Road closures will be required to adhere to the applicable restriction specifications.

• Project sequencing: Maintaining the existing travel lane configuration in each direction during construction will create less delay for motorists. Although sequenced construction requires a longer construction period, it minimizes impacts to traffic.

• Temporary paving: Temporary widening to the north will accommodate a temporary westbound bicycle and pedestrian facility and shift of traffic and allow contractor access to construct permanent eastbound bicycle and pedestrian facilities on the south side of the road.

• Limiting full-depth reconstruction: Full-depth reconstruction is minimized by typically sawcutting 1-foot into travel lanes thereby reducing impacts to traffic staging. New paving longitudinal joints will be located away from the sawcut joint.

• Detours:

o Vehicular – Deployment of PCMS and other public outreach efforts will encourage drivers to find alternate routes.

o Bicycle and pedestrian – For through bikers there is an alternate route using adjacent local streets to avoid construction.

• Temporary Portable Signals: Temporary signals will be required for one lane operation on two lane collector and local roadways.

• Flagging: Flaggers will be required for night time lane closures in intersections and on side streets with no alternate access available.

• Partial Closures: Side streets with alternate access will be closed to through traffic allowing local use only.

• Business Access: Business accesses will be constructed under traffic. To help motorists accessing businesses, blue tubular markers will be used to delineate the temporary access point.

• Coordination with adjacent construction: The coordination of this project with other projects in the area, as discussed in Section 3.3, will help to avoid unnecessarily compounding of traveler delay.

• Full-time traffic control supervisor (TCS): Maintaining a full-time TCS on-site will allow one person to be dedicated to traffic control and not be distracted by other construction activities. Benefits include the ability to make quick decisions and implement contingency plans, as needed.

7.4 Incident/Emergency Management Strategies The possibility of a minor incident increases within construction zones. Given that minor incidents can potentially evolve into a major event, an incident management plan is a helpful tool to detect and remove incidents from the highway and restore traffic capacity as quickly and safely as possible.


38 | May 7, 2018

7.5 Alternate Route Strategies Running parallel to I-205 is I-5, which has similar capacity. During closure work on I-205, PCMS can be placed at selected locations on the ODOT system (I-5/I-205, and I-84/I-205 system ramps, etc) in addition to adding messages to the existing VMBs. Doing so will notify drivers of I-205 construction and encourage drivers to use I-5. OR 99E also runs parallel to I-205 and may serve as a secondary alternate route.

8 Incident Management Plan Incident management is a planned and coordinated program that detects and removes incidents from the highway and restores traffic capacity as safely and quickly as possible. ODOT Region 1 has an incident management program in operation that is operated from the Region 1 Traffic Management and Operations Center (TMOC). Any incidents that impact traffic flow during construction will need to be coordinated with the TMOC. The Emergency Communication Plan and Contingency Plan are two important tools for incident management that are described in the following sections.

8.1 Emergency Communications Plan The Emergency Communication Plan describes how communications will occur and lists important contact information for responding to an incident. Important elements include:

• Goals and objectives of the plan

• Key contacts and their contact information

• Emergency and essential services contacts

• Definitions of emergencies and the appropriate response and communications for each type of emergency

• Roles and responsibilities of the stakeholders who execute the plan

• Maintaining an updated list of emergency contacts for use in the event of an incident shall be the responsibility of the contractor. A template has been included in Appendix D to help guide the contractor in developing an Emergency Communication Plan

8.2 Contingency Plan As a part of the Incident Management Plan, the Contingency Plan will include both traffic and contractor contingency plans. The traffic Contingency Plan addresses specific actions that will be taken to restore or minimize traffic effects when congestion or delay exceeds original estimates due to unforeseen events such as work-zone accidents, higher than predicted traffic demand, or delayed lane closures. The contractor Contingency Plan addresses activities under the contactor’s control within the work zone. A guideline has been included in Appendix E to help guide the contractor (once under contract) in developing a Contingency Plan.


May 7, 2018 | 39

8.3 Mobility Communication Plan The Mobility Communication Plan provides communication strategies for informing affected road users, the general public and various project stakeholders about the project and changing work zone conditions. The construction project manager and Region 1 Community Affairs staff will work together to generate weekly construction reports for distribution to the news media, an interested party’s mailing list and TripCheck. For this project, media releases will need to be coordinated with and reviewed by ODOT Region 1 staff. ODOT MCTD will address communications with the freight industry. It is recommended that all other communications not described above be disseminated by ODOT Region 1 staff. Table 5 summarizes contractor and ODOT communication responsibilities.

[Section 5.485 repealed by Ordinance No. 1496, amending the West Linn Municipal Code by adding new Section 5.487 entitled Sound Levels and Noise, adopted on August 20, 2003.] 5.487 Sound Levels and Noise. Purpose. The City Council of the City of West Linn finds that low and moderate ambient noise levels are a

West Linn Code


significant City amenity. They find further that the level of noise that exists in a community directly affects the livability of the community and the health, comfort and welfare of its residents. It is, therefore, the express intent and purpose of this ordinance to establish noise level standards that protect and improve the quality of life of West Linn’s residents at work, rest and play and that can be objectively measured and enforced. Terminology. All terminology used in this ordinance, not defined below, shall be in accordance with applicable publications of the American National Standards Institute (ANSI) or its successor body.

Measurement of Sound.

(A) All measurements called for in this ordinance shall be made with a sound level meter in good operating condition, meeting the requirement of a Type 1 or Type 2 sound meter, capable of both fast and slow response and meeting ANSI Standard S1.4-1983(R1990) and S1.4A-1985. (B) All sound measurement readings shall be taken in accordance with the rules of location and distance established in this ordinance and following the procedures set forth in the Sound Measurement Procedures Manual (NPCS-1) or successor publication available from the Oregon Department of Environmental Quality. Where the rules of measurement and distance established in this ordinance differ from those of the (NPSI-1) Manual, the provisions of this ordinance shall take precedence. (C) When the location or distance prescribed in this ordinance for measurement would result in misleading or

inaccurate results, measurement may be taken at other locations or distances using appropriate correction factors.

Definitions.

A-Scale (dBA). The sound level in decibels measured using the A-weighting system as specified in ANSI S1.4-1983(R1990) and S1.4A-1985 for sound level meters. The A-weighting system corrects for the fact that the sensitivity of the human ear varies with pitch, being more sensitive to higher pitch sound.

Automobile Intensive Business. Any business that services, repairs or fuels automobiles or other on-road vehicles or that employs a drive-through window or that generates or is intended to generate more than 50 vehicle roundtrips in any one business day.

Ambient Noise Level. The total noise associated with a given environment, being a composite of sounds from many sources both near and distant. For the purposes of this ordinance ambient noise levels shall be measured using the A-Scale and in accordance with the standards of the Sound Measurement Procedures Manual.

Amplifying Equipment. Public address systems, musical instruments, and other similar sound-producing devices which are electronically amplified.

City. The City of West Linn, Oregon, or the area within the territorial city limits of the City of West Linn, Oregon, and such territory outside of this city over which the city has jurisdiction or control by virtue of ownership, or any Constitutional or Charter provision, or by law.

West Linn Code


Construction. Any and all activity necessary or incidental to the erection, demolition, assembling, altering, installing, repair or equipping of buildings, roadways and utilities. It shall include land clearing, grading, excavating and filling before, during or following such activity.

Decibel (db). A logarithmic unit of sound measurement equal to 10 times the log (base 10) of the ratio of a sound pressure being measured, to a reference sound pressure. A 10 db increase is equivalent to a doubling of loudness, while a 20 db increase would be equivalent to four times as loud as a reference sound. A 3 db increase is twice the sound power, while a 6 db increase is twice the sound pressure. (See sound pressure level definitions.) Table I - Examples of Decibel Levels:

10 db light whisper 60 db noisy office

20 db quiet conversation 70 db normal traffic, quiet train

30 db normal conversation 80 db rock concert, subway

40 db light traffic 90 db heavy traffic, thunder

50 db typewriter, loud conversation 100 db jet plane at takeoff

Domestic Power Tools. Any mechanically powered saw, drill, sander, grinder, lawn or garden tool, or similar device generally used out of doors in, or impacting, residential areas.

Dynamic or Compression Braking Device (commonly called “Jake” brakes). A device used primarily on trucks and buses to convert the motor from an internal combustion engine to an air compressor for the purpose of vehicle braking without the

West Linn Code


use of wheel brakes.

Emergency Work. Work performed to restore property to a safe condition following severe inclement weather or natural disasters; work required to restore public utilities or to protect persons or property from imminent exposure to danger.

Frequency. The time rate of repetition of a periodic phenomenon, measured in Hertz (Hz), (cycles per second) -- in the case of sound, the pitch.

Impulse Sound. A single pressure peak or a single burst (multiple pressure peaks) for a duration of less than one second as measured on a peak unweighted sound pressure measuring instrument.

Light Household Maintenance. Work done on a house or apartment that does not require a building permit or other planning approval.

Narrow Band Sound. Sound characterized by normal listeners as having a predominant pitch or series of pitches; sound described by such listeners as “whine,” “hiss,” “toot,” or “wail”; a sound whose frequencies occupy an octave band or less.

Noise Sensitive Building. A building which is devoted, in whole or in part, to a noise sensitive use.

Noise Sensitive Use. Any use which is adversely affected by ambient sound or noise, as in the use of real property for residential occupancy, schools, churches, public libraries, or hospitals. This definition includes any place where people normally sleep.

Octave Band. An interval in Hertz between two frequencies having a ratio of two to one. For purposes of this ordinance, octave band sound pressure levels will be measured at the following center frequencies: 31.5, 63, 125, 250, 500, 1000, 2000, 4000, and 8000 Hz.

Off-Road Recreational Vehicle. Any motor vehicle, including watercraft, used off public roads for recreational purposes. When a road vehicle is operated off-road, the vehicle shall be considered an off-road recreational vehicle if it is being operated for recreational purposes.

Period of Observation (Enforce-ment). For the purposes of enforcement of this ordinance, the “Period of Observation” need be no longer than the minimum period of time necessary to determine if a violation of a “Statistical Noise Level” has occurred, and is reported as an “L number.” The L number designates the recommended period of observation as a percentage of the testing time (generally one hour). Thus, L50 = 30 minutes; L10 = six minutes; and L1 = 36 seconds. For example, if after testing for one minute, it is noted that an L1 “Statistical Noise Level” has been met or exceeded for 40 seconds, it is not necessary to test for a longer period of time to determine that a violation has occurred.

Period of Observation (General Testing Time). A duration of sixty minutes. A longer time period may be used if required by special circumstances.

Person. The United States government and agencies thereof, any state, individual, public or private corporation, political subdivision, governmental agency, municipality,

West Linn Code


industry, co-partnership, association, firm, trust, estate or any other legal entity whatever.

Plainly Audible Sound. Any sound for which the information content of that sound is unambiguously communicated to the listener, such as, but not limited to understandable spoken speech, comprehension of whether a voice is raised or normal, or comprehensible musical rhythms and bass lines.

Public Road. Any street, alley, road, highway, freeway, thoroughfare, urban trail, or section thereof used by the public or dedicated or appropriated to public use.

Sound Level. The “Sound Pressure Level” obtained by the use of a sound level meter. When the level is specified in dBA, the “A” weighting frequency network is employed. Otherwise, the linear un-weighted sound pressure level is understood.

Sound Pressure Level. Twenty times the logarithm to the base 10 of the ratio of the root-mean-square pressure of the sound to the reference pressure. Sound Pressure Level is given in decibels (dB). The reference pressure is 20 micropascals (20 micronewtons per square meter). (See Decibel.)

Statistical Noise Level. The “Sound Level” which is equal to or is exceeded a stated percentage of the time within the “Period of Observation.” An L10 = 60 dBA means that within the “Period of Observation,” 60 dBA can be equaled or exceeded only 10 percent of the time; i.e., six minutes total within any given hour.

Vehicle Roundtrip. For the purposes of this ordinance, a “Vehicle Roundtrip” constitutes entering and exiting a place of business or entering the parking facility associated with or available to a business, parking and then later unparking the vehicle and exiting the parking facility.

Warning Device. Any device which signals an unsafe or potentially dangerous situation.

Working Hours. The hours during which people are ordinarily present at any workplace.

Workplace. Any place where people normally perform labor or pursue an occupation, either for remuneration or as volunteers.

MAXIMUM PERMISSIBLE SOUND LEVELS.

Noise Sensitive Use. Except as specifically provided elsewhere in this ordinance, no person shall cause or permit the creation or continuance of any sound in excess of the limits set forth in Table 1 as measured at the property line of any “Noise Sensitive Use.”

West Linn Code


TABLE 1

Allowable Sound Levels at Noise Sensitive Use Property Line

Type of Sound 7 a.m. to 7 p.m. 7 p.m. to 7 a.m.

Statistical Noise L50 = 55 dBA L50 = 45 dBA

L10 = 60 dBA L10 = 50 dBA

L1 = 70 dBA L1 = 55 dBA

Impulse Sound 95 dB 80 dB

Interior Levels. Whenever a noise sensitive use is contained within the same building as a noise source, measurement of that noise source shall be made within the confines of the noise sensitive use. In such situations the maximum allowable noise levels as established in Table 1 shall be decreased by 10 dBA (or 10 dB in the case of impulse sounds) for both measurement and enforcement. Narrow Band Sound. When the City Council, Planning Director, or Planning Commission has reasonable cause to believe that an existing or prospective noise source is causing or is likely to cause a “Narrow Band Sound” that is grating, annoying, irritating or which interferes with the comfort and rest of the citizens or is contrary to the purpose statement of this ordinance but which would not register on the A-weighted scale as being in violation of Table 1, then the following criteria shall apply. No person shall cause or permit the creation or continuance of any narrow band sound for a period of longer than 10 minutes in any hour that meets or exceeds the levels in Table 2 at the following octave band frequencies:

West Linn Code

Any new commercial or industrial development subject to approval or review by any City department or elective or appointed body shall not receive such approval if it would violate this ordinance. Ambient Degradation Associated With New Noise Sources. Any new commercial or industrial development located on a previously unused industrial or commercial site shall not cause or permit the operation of a noise source if the noise levels generated or indirectly caused by that noise source would increase the ambient statistical noise levels, L50 or L10, by more than 5 dBA in any one hour. In some instances the ambient degradation standard may establish lower allowable dBA levels than those established in Table 1, and in those instances the lower level shall apply. The purpose of this rule is to support the intent of this ordinance to preserve existing low ambient noise levels wherever they exist within the City.

PROHIBITED NOISE MAKING ACTS The following noise producing actions are deemed by their uniquely intrusive nature to violate the intent and purpose of this ordinance and to have a materially detrimental effect on the peace, ease, repose and livability of the City irrespective of the maximum sound levels established previously in Tables 1 and 2. No person, therefore, shall cause or permit the creation or continuance of any prohibited noise making action, subject to the penalties established in this ordinance. Amplified Sounds. The playing or use of any radio, phonograph, tape player, CD player, television set, stereo system, or amplifying equipment such as to be plainly audible at the property edge of any noise sensitive use between the hours of 7 p.m. and 7 a.m. or in cases where the noise source and noise sensitive use share a common wall or are in the same building as is plainly audible within the noise sensitive use. (See Plainly Audible Sound.)

Idling Engines on Motor Vehicles. Allowing any motor vehicle with a Gross Vehicle Weight Rating (GVWR) of 8,000 pounds or greater to idle for more than fifteen (15) consecutive minutes between the hours of 7 p.m. and 7 a.m. if such idling produces sound in excess of 45 dBA at the property line of any noise sensitive use. Leaf Removal. Removal or collection of leaf material by commercial or

paid operators between 7 p.m. and 7 a.m. weekdays and 7 p.m. and 8 a.m. weekends and federal holidays. Includes collection and removal by sweeping, blowing or vacuum equipment. Shouting, Yelling, Screaming. No person shall shout, yell, scream or make other loud vocal utterances such that they are plainly audible at the property line of a noise sensitive use between the hours of 7 p.m. and 7 a.m. Excepted are those persons warning another of a danger or in danger themselves or in real physical distress. Sirens, Horns, Clarions. The sounding of any horn, siren or other such device anywhere in the City limits except as a necessary warning of danger. Tampering. The removal or rendering inoperative by any person other than for the purposes of maintenance, repair, or replacement, of any noise control device or element of, especially but not limited to the following: (A) Any product manufactured to meet specified noise emission limits under Federal law pursuant to the Noise Control Act of 1972 (PL 92-574). (B) Motor vehicles of model year 1975 and subsequent that were sold new in the State of Oregon.

Appendix D. Emergency Communication Plan

Emergency Communications Plan Template 1

Emergency Communications Plan Template Advance communication prevents community problems Communication is the cornerstone of a successful project. Much advance work has been done on this project to inform the public of impacts they can expect during construction, and to listen to community concerns so ODOT can minimize adverse impacts as much as possible. It is important that we keep our commitments and provide advance warning to the community when impacts are expected. This is a daily commitment shared by the project office, contractor and staff from both community and public affairs. In addition, there will be times when an emergency or crisis demands a quick communications response. This plan addresses such unexpected occurrences.

A prompt and accurate response Prompt dissemination of information ensures that people are informed of what is happening and how they might change their plans to mitigate the event's affect on them. It is also vital because if the Oregon Department of Transportation does not tell its story right away, someone else – a motorist, a witness, someone who potentially has fewer facts – will tell the story for us. Accurate information – even when it is not good news – lends credibility to ODOT and its desire to keep the public informed. It goes hand-in-hand with timely communications in allowing the public to make decisions based on the facts available. Coordination with other agencies before releasing information is critical. All agencies involved in an emergency – local, state, federal, and private sector partners – should communicate the same messages. Conflicting messages damage the credibility of all participating agencies. The public may not take appropriate action to protect themselves or others if they receive conflicting information.

The importance of a communications plan A plan ensures that all pertinent information – names, phone numbers, key messages, action plan outline, time line, media strategies, etc. – are in the possession of designated emergency/crisis responders so that response can be prompt, accurate and coordinated. This emergency communication plan is designed to provide a basic outline for how to respond to some of the emergencies or crises that may occur during the project. It gives clear and systematic directions for establishing a chain of command, prioritizing audiences, developing messages, and delivering them in an organized fashion to a variety of audiences: employees, the media, the public. It is vital that responses be coordinated so that ODOT, its contractors, subcontractors and jurisdictional partners speak with "one voice" throughout all stages of the crisis and the public does not receive conflicting messages.

Who is the audience? During an emergency, ODOT has two primary audiences. The first group is the people who need to act to help respond to the emergency: police, fire, medical, and HAZMAT.


The second group needs information in order to protect/prepare themselves. Included in this group are local businesses, residents, motorists and the media.

Types/definitions of emergencies/crises As stated before, an emergency is anything that has the potential to harm life, property or the environment. Erosion of the public's confidence in ODOT on this project is also considered a crisis. The OTIA bridge projects have the potential for all four. Emergencies can take many different forms and each requires a different level of response. This plan will address some of the many kinds of emergencies/crises that may occur on this project. Please remember, all emergencies/incidents, big or small require a prompt, accurate and coordinated response.

Release of contaminates into the air/water The accidental release of contaminates into the air/water (regardless of fault) would be considered an emergency. It has the potential to harm life (human and animal) by contaminating the environment.

Unanticipated traffic or pedestrian delays or detours Despite everyone’s best efforts to communicate construction impacts on traffic, there will be times when lanes or ramps are closed longer than expected. Every effort must be made to avoid these situations. The traffic control plans and contract provisions for lane and ramp closures are included to prevent major traffic disruptions. In the event of an unanticipated traffic delay, it is essential that the project staff work with the contractor to reopen lanes or ramps as soon as possible. Liquidated damages may be applied against the contractor for these incidents, but ODOT needs to maintain safe traffic flow on our roadways. When these incidents occur, the public affairs and community affairs staff need to be involved early in the incident to help coordinate the flow of information through the news media and other information distribution channels.

Vehicle accident/incident (non-injury) Much of Oregon’s highway and bridge construction takes place "under traffic." This means construction crews share roadway space with thousands of motorists every day. Work-zone wrecks (regardless of fault) would be considered an emergency. An incident/accident would be defined as any occurrence involving damage to private property or vehicles. This also includes any unplanned incident that delays traffic for 20 minutes or more. Please use good judgment and call if there is any doubt. A minor incident can attract the attention of the public or media.

Serious vehicle accident/incident (injury/death) Accidents/incidents resulting in injury/death of motorists, passengers, and construction workers would be classified as extremely serious. If such a situation occurs, prompt notification is critical.


All pedestrian/bicycle incidents Pedestrian facilities are defined as either formal sidewalks or informal pathways that appear to be used frequently. Incidents occurring on pedestrian facilities, bicycle lanes or the adjacent roadway (regardless of fault) would be considered an emergency that needs to be reported to the appropriate project authorities, including public and community affairs staff. Closures of pedestrian facilities must be clearly thought through, discussed with public and community affairs and with pedestrian facility authorities. All discussions of closures must include alternate/detour route considerations.

Citizen Reports of Incidents Depending on when an incident occurs, the District Office may be made aware of it before the inspector or construction office. This is especially true on weekends and outside of regular work hours. While the chances of a serious incident at the site drop dramatically during non-work hours, there is still the potential. Frequently, citizens report relatively simple issues like barrels or signs that have been knocked over or steel plates that have started to move. These issues are not the responsibility of the Maintenance offices and must be dealt with immediately. Once again, a prompt response is crucial.

Roles and Responsibilities The reporting structure and roles/responsibilities are key to a successful emergency communication effort. The following briefly outlines those roles/responsibilities when an incident occurs: ODOT's on-the-scene inspector notifies ODOT's Project Coordinator _____________________, who notifies Project Manager _____________________ and Assistant Project Manager _____________________, who notifies Public Affairs Manager _____________________ and Traffic Manager _____________________. Until further notified, the on-scene inspector will be the main, on-site representative, and will be considered the communication link to key ODOT personnel only. This individual will not talk to the media or general public, or discuss the situation with anyone other than key contractor personnel. Project Manager _____________________ or his designee notifies Area Manager _____________________ and Region Manager _____________________. Region Manager _____________________ will notify ODOT District ___ Manager _____________________, and Maintenance/Operations Manager _____________________. Public Affairs Manager _____________________ will notify Community Affairs Manager _____________________. These individuals, including Public Affairs Manager _____________________ and Traffic Manager _____________________ will determine lead roles/spokesperson(s). These individuals will also determine the course of action/response to the emergency, identify key messages and further define roles and responsibilities.


Public Affairs Manager _____________________ will set up the information/command center. Until further notified, this center will be located at ODOT's Region 5 Headquarters, 3012 Island Avenue, La Grande, Oregon.If deemed necessary, Public Affairs Manager _____________________ will identify/coordinate a second on-the-scene ODOT representative. He will notify key multi-jurisdictional communication team members as necessary/needed. He will also act as spokesperson and will coordinate any off-site or on-the-scene information/command center, if necessary. Community Affairs Manager _____________________ will be responsible for notifying businesses, the general public and residents who may be impacted by the incident, and will coordinate any special needs with the incident command staff. Once a course of action has been determined, Area Manager _____________________ or his designee will alert the appropriate agencies:

State and local police/fire/rescue Oregon Department of Fish & Wildlife Oregon Department of Environmental Quality Federal Environmental Protection Agency

The contractor and sub-contractors are employees of ODOT. They will participate in the emergency response as determined necessary by ODOT or by contractual obligation. Contract employees will not talk to the media/general public, or discuss the situation with anyone other than with key ODOT personnel.

Information Sources Recorded ODOT highway construction information is available 24 hours a day by dialing 503-223-0066.The project hot line number 503-______-________ is available 24 hours a day for crisis calls.

Appendix E. Contingency Plan

Contingency Plan Guidelines 1

Contingency Plan Guidelines

ExplanationA Contingency Plan includes both traffic and contractor contingency plans. The traffic contingency plan addresses specific actions that will be taken to restore or minimize effects on traffic when the congestion or delay exceeds original estimates due to unforeseen events such as work-zone accidents, higher than predicted traffic demand, or delayed lane closures. The Contractor’s contingency plan addresses activities under the contactor’s control in the work zone.

DocumentationPrior to construction, the Contractor is required to provide the following documentation to be kept on hand at each construction site.

1. Communications, Roles and Responsibilities – A plan for lines of communication, individual roles and responsibilities shall be developed by the Contractor. The contractor shall designate an individual (such as the Traffic Control Supervisor) as a point of contact within their organization. The Contractor’s plan should clearly state lines of communication and authority within their organization as well as reference those outlined in the Emergency Communications Plan or Mobility Communications Plan as applicable.

2. Contractor’s Contingency Plan – The Contractor shall develop a contingency plan for each construction site based on site specific conditions.

3. Contingency Plan Trigger Points - The following conditions or events will require a Contingency Plan to be implemented (documentation of these trigger points shall be included in the Contractor’s Contingency Plan):

Weather Conditions: __________________________________________ ___________________________________________________________Traffic Conditions (e.g. high traffic demand level): __________________ ___________________________________________________________Other Events (e.g. accidents): ___________________________________ ___________________________________________________________

4. Coordination Strategy – The Contractor shall develop a coordination strategy. Any contracting personnel recognizing a condition that would warrant implementing a Contingency Plan shall notify the Traffic Control Supervisor or other individual that has been designated as a “Point of Contact” for the contracting organization. The contracting organization’s representative shall conduct coordination efforts as outlined in the Coordination Strategy. The Coordination Strategy shall include any special agreements between individuals or agencies. Individuals to be involved in the Coordination Strategy should be included on the Project Contact Information List.

5. Project Contact Information – The Contractor shall develop and maintain a contact list of key project personnel (e.g. Traffic Control Supervisor, Resident Engineer, Maintenance Supervisor, Permit Inspector, State Patrol, other ODOT


representatives). Contact information for individuals on the Emergency Communications Plan and Mobility Communications Plan should also be included. See attached sample forms.

6. Traffic Contingency Plan – The Contractor shall develop a contingency plan to restore minimum operating capacity of the roadway.

7. Required Resources – The Contractor shall provide a list of available of stand-by equipment required for implementation of Contingency Plans. This list should include location of equipment and quantities if appropriate. Examples of items that may be included on the list are: portable changeable message signs, concrete barrier relocation equipment, etc. In addition, include the availability of local ODOT personnel for callout (normally requiring a Cooperative Agreement).
