Transportation Engineering

190.1 General

To ensure the acceptable completion of permitted private or public improvements, a Performance Surety and/or Warranty Surety may be required and integrated into Engineering related permits.

1. A Performance Surety shall be required prior to:
   1. Issuance of a Utility Permit for mainline utilities or other utility work that significantly impacts the existing roadway except when performed by a "public utility company or municipal authority" per County Code 7.03.130.E. Per County Code, if an existing roadway is left in disrepair and is a hazard to the traveling public, the County may repair the road and call the surety to cover the cost of repairing the road. If the Performance Surety is redeemed to repair a road during the course of a project, an additional surety may be required by the County to complete the project;
   2. Issuance of a Development Permit impacting an existing roadway under the jurisdiction of the County. If at any time, an existing roadway is left in disrepair and is a hazard to the traveling public, the County reserves the right to repair the road or call the surety to cover the cost of repairing the road. If the Performance Surety is redeemed to repair a road during the course of a project, an additional surety may be required by the County to complete the project;
   3. Issuance of a Certificate of Occupancy when all improvements required by the Development Permit and the land use requirements are not completed and accepted; or
   4. Recordation of a plat when all improvements required by the Development Permit and the land use conditions are not completed and/or accepted.
   5. A Performance Surety may be required prior to issuance of a Right of Way Permit for events that have a strong potential of damage occurring to the right-of-way.
2. Substantial Completion of residential partitions and subdivisions shall be achieved prior to acceptance of any surety for guarantee of work to record a plat.  Requests for acceptances of a surety for guarantee of work without achieving Substantial Completion will be evaluated by Engineering using the criteria in Section 190.2 if minimum fire, life and safety issues are met.
3. A Warranty Surety shall be required for improvements located in the right-of-way under County jurisdiction after the acceptance of improvements.

Typically, Performance Surety or Warranty Surety will not be required for Entrance Permits or Right-of-Way Permits, but may be required by the Road Official.

190.2 Substantial Completion for Development Permits

Substantial completion is achieved when:

1. All required right-of-way dedications and easements have been accepted or are shown on the final plat.
2. The sanitary sewer mainline and service laterals under subject roadways are constructed and accepted.
3. The roadway drainage system is constructed and accepted, including LIDA when required.
4. The water main line and service laterals are constructed and accepted and water is available for fire suppression.
5. Conduits for franchise utilities within the roadway are installed and accepted.
6. The pavement wear course is installed.  If pavement is not required, the full gravel structural section has been placed and properly compacted.
7. Shared private roadways and emergency access turnouts and turnarounds are constructed.
8. All other land use or Development Permit conditions required to be met prior to plat or occupancy approval are completed.
9. The EOR shall complete a Certificate of Compliance and Completion.

190.3 Performance Surety

Acceptable Performance Sureties include a Performance Bond, a Security Agreement (commitment of funds), or a Cash Acknowledgement.

1. Performance Bonds shall be provided only through State regulated surety companies
2. A Security Agreement, or commitment of savings or loan proceeds, shall be through State regulated financial institutions. 
3. A Cash Acknowledgment is a cash surety held directly by the County.
4. A Development Agreement shall accompany all types of sureties and be recorded.

190.3.1 Forms

All sureties and Development Agreements shall be submitted on forms provided by the County and are subject to review and approval by County Counsel.

190.3.2 Timeframe/h3>

Sureties shall be in effect at the time of plat approval or issuance of a Certificate of Occupancy and until County acceptance of the improvements resulting in release of the surety. 

190.3.3 Amount

1. The financial amount established for the Performance Surety shall be equal to 125% of the estimated value of the improvement. 
2. An Engineer's estimate is required and shall be approved by Engineering.  A contractor's bid or estimate is not acceptable.  The surety shall cover the County's cost for completing the work with public contracting procedures and include project management and inspection services.
3. The minimum amount for Performance Sureties shall be $10,000.  The minimum amount for all other sureties including the Cash Acknowledgment shall be $2,500.
4. Engineering will not approve more than one surety reduction throughout the life of the project, not including the reduction of Performance Surety to the Warranty Surety.

190.4 Maintenance and Warranty Period for Development Permits

1. Typically, the Warranty Period will begin when all improvements, with the exception of street trees, are accepted by the County.  If there are remaining improvements to be constructed, the Warranty Surety will also include a Performance Surety.  All outstanding performance items shall be guaranteed at 125%. This combined surety may require the minimum warranty period to be extended to two years from the date all performance improvements have been completed.
2. The applicant shall provide a Warranty Surety as part of a Development Permit for work located in a public right-of-way under County jurisdiction.  The Warranty Surety/maintenance requirements shall be held for a minimum of two years.
3. The required Warranty Surety shall be valued at 25% of the Engineer's estimate and approved by Engineering.
4. The County may require an extension of the Warranty Surety/maintenance period for more than the minimum required if the required improvements show signs of failure during a final inspection and work is completed to correct these deficiencies.
5. The Warranty Surety does not expire and may only be released after a final inspection has been completed and the minimum warranty period has elapsed. At the time of final warranty inspection, any items not completed or maintained to County standards will be included in a punch list provided to the applicant and/or guarantor. These items shall be addressed prior to the release of the Warranty Surety.

190.5 Maintenance and Warranty Period for Utility Permits

1. Utilities installed as part of Utility Permits do not have a Warranty Period.
2. When related to a Development Permit, the Warranty Surety/maintenance requirements for utility work will follow those listed under 190.4 for work located in a public right-of-way under the jurisdiction of the County.

190.6 Acceptance of Work

Prior to County acceptance of the improvements and release of the Performance Surety and/or Warranty Surety/maintenance period, the following shall occur:

1. The applicant shall repair any damage caused by the construction of the work to any public roads, private roads and/or property that is not part of the project as well as any identified haul routes per Section 225.6.
2. The applicant shall perform a thorough cleaning of the roadway surface and storm drain system.
3. If a private PI is required, the PI shall conduct an inspection of the improvements.
4. If the private PI indicates that the work is complete, the EOR shall complete a Certificate of Compliance and Completion.
5. The County shall conduct an inspection of the improvements.
6. The County shall make a determination of completion in conformance with the permit. 
7. Any deficiencies resulting in non-acceptance of the work permitted in the Development Permit shall be identified in writing on a punch list and presented to the applicant with a date named for correction and completion. 
8. Upon correction of the noted deficiencies and the determination that all work is in conformance with the requirements, repeat steps a) through f).
9. When the improvements are found complete and the work is accepted, the Performance Surety will be released and the Warranty Period will begin.
10. Once the Warranty Period has passed, and there are no defects in workmanship found by County inspection, the Warranty Surety will be released.

190.7 Acceptance of Roads

When the permit requirements are met and the Warranty Period is over and all sureties have been released, the County will then accept the road right-of-way as dictated by the road's classification. 

190.8 Nonperformance of Permit

Failure to complete the project prior to expiration of the Development Permit and Utility Permit shall be construed as nonperformance and may be considered a violation of the permit.  The surety may be demanded in order to bring the project to completion.  If compliance is not achieved, the permit is subject to code enforcement.  Development Agreements should not be extended unless there is adequate surety to guarantee the improvements through the extended period.

180.1 General

The applicant shall provide the County with access and be furnished with every reasonable facility for inspection of the work, is in accordance with the requirements and intent of the plans, specifications, permit conditions and land use requirements (collectively known as "the permit").

180.2 County Inspector Authority and Duties

A County inspector will be assigned to each project to inspect materials and work performed.  Such inspection may extend to any or all parts of the work and to the preparation and/or manufacture of the materials to be used.

The County inspector is not authorized to:

1. Revise, alter, or relax requirements of the permit.
2. Direct how the work is to be performed.

The County inspector has the authority to:

1. Inspect work performed and materials furnished, including without limitation, the preparation, fabrication, or manufacture of materials to be used.
2. Reject deficient materials or work.  The inspector may advise the applicant or contractor of any faulty work or materials; however, failure of the inspector to advise the applicant or contractor does not constitute acceptance or approval. 
3. Temporarily suspend the work for safety deficiencies for safety issues, lack of compliance with the permit, or if the requirements of a private primary inspector are not being fulfilled per Section 180.3.
4. Recommend revisions or revocation of the permit per Section 130.3.8.
5. Allow work to proceed after deficiencies have been corrected.
6. Exercise additional delegated authority.

180.3 Primary Inspector

In the case of larger projects, additional inspection services are required beyond County provided inspection services. These inspection services are more comprehensive and intensive than County inspection services and are the responsibility of the applicant and Engineer of Record ("EOR").  In those cases, the applicant shall provide a primary inspector at their cost. 

A primary inspector's duties may be performed by a qualified representative of the engineering firm or other qualified third party inspector.  The applicant shall be responsible for primary inspection services of all improvements permitted by Engineering at no cost to the County.  A primary inspector ("PI") shall not have a corporate ownership or have real property interest in the development for which the improvements are required. 

Utility Permit work proposed by a public utility may provide qualified public utility engineering staff or a qualified third party to satisfy the requirements of a PI with the approval of Engineering.

180.3.1 Developer Engineer Agreement

When a primary inspector (PI) is required as part of a development project, the applicant shall enter into a Developer Engineer Agreement prior to Development Permit issuance to have the EOR responsible for primary inspection services.

180.3.2 Certificate of Compliance and Completion

At the completion of a project, the EOR shall be responsible for providing a Certificate of Compliance and Completion to establish that the project was completed as required by the permit.

180.5 Required Inspections of ADA Accessibility Features

1. All ADA accessibility features within the County right of way, including but not limited to sidewalks, paths, crosswalks, curb ramps, medians, traffic islands, signs, on-street parking, and pedestrian traffic signal accessibility features including clear spaces shall be inspected for compliance with ADA requirements. No project shall be accepted as complete without documentation prepared by the County inspector showing that all ADA accessibility features meet requirements or have a previously approved exception per Section 170.2.
2. Forms Inspection - The forms inspection shall determine if the forms and survey marks for an accessibility feature are placed in such a manner to meet requirements. The contractor shall provide a signed written record of the dimensions and relative elevations of the forms for an ADA accessibility feature prior to placement of pavement using an inspection report form supplied by the County.  A diagram of the ADA accessibility feature shall be provided and at least one photo of the forms prior to fabrication. Dimensions of all sides of the accessibility feature shall be measured with a steel tape and compared with the approved design. The height of the curbs and any corners shall be determined in relation to the lowest point on the accessibility feature using a level. The completed forms inspection report provided by the contractor including diagram and photos shall be included in the project file.
3. Post fabrication inspection - The post fabrication inspection shall determine compliance of the accessibility feature with all ADA requirements. The inspection shall be conducted using the standard county inspection checklists and required measurement tools and techniques. Dimensions and curb heights shall be determined using standard methods. Slopes shall be determined using the ODOT specified 6 inch and 2 foot smart levels with multiple slope measurements taken for each feature used to determine compliance. Any element that fails to meet required PROWAG standards shall be replaced by the applicant and re-inspected for compliance. If it is determined that an ADA feature does not comply with PROWAG standards, the applicant shall have the option of appealing that determination. For the appeal the builder shall retain a Land Surveyor to conduct a survey of the ADA accessibility feature and prepare a plan showing actual elevations and slopes for the accessibility feature. If the survey plan demonstrates that the accessibility feature meets PROWAG standards the applicant will not be required to replace that accessibility feature. If the survey plan demonstrates that the accessibility feature fails to meet PROWAG standards, then the accessibility feature shall be replaced at the applicant's expense and re-inspected for compliance.

180.6 Inspection Requests

A minimum of two business days' notice shall be provided for inspection requests via the method described on the permit, which also lists the required inspections.

180.7 Failure to Obtain Inspection

If the County inspector is not able to inspect the work after proper notice, the applicant should take measures to reschedule the work.  Work that is completed without the required inspections, as dictated by the permit or as required by Section 180 is subject to rejection and/or code enforcement procedures of the County Code. 

The County inspector may pre-approve work to continue without County inspection with proper documentation provided by a primary inspector or other documentation.

170.1 Design Modifications

1. It is not the objective of these Standards to limit the creative efforts of engineers in providing alternate solutions to specific problem areas or to relieve the responsibility for professional engineering judgment. 
2. Practical design modifications that preserve the function and safety of the roadway system and offer benefits to aesthetics, resource protection, ease of maintenance, and livability are encouraged.
3. Approval of non-compliant or alternate specifications and standards under the purview of these Standards may be requested utilizing the following process.  This process does not apply to land use requirements or Conditions of Approval generated through the ZDO or the Comprehensive Plan.  The ADA exception process follows the procedures detailed below in Section 170.2. 

170.1.1 Modification Request Submittal

1. Requests to modify design standards shall utilize the Clackamas County Design Modification Request form.  Design Modifications are typically submitted prior to land use application approval or early on in the design process when related to capital construction.
2. Land use conditions of approval are commonly written so that there is little, if any, flexibility after land use approval.  For this reason, it is imperative that design modification requests be addressed prior to land use approval.  If a design modification is requested after the land use conditions of approval are issued, additional application for a modification of the conditions of approval or a new land use application through the Planning and Zoning Division may be required.

170.1.2 Criteria for Modification of Standards

The County may grant a modification when the use thereof does not compromise public safety or the intent of the County's standards and any one of the following conditions are met:

1. The subject standard is deemed not applicable in the particular circumstance.
2. Topography, right-of-way or other geographic conditions impose an environmental concern or provides a constraint for constructability and an equivalent alternative, which can accomplish the same design intent, is available.
3. A minor change to the standard and the modification is required to address a specific design or construction constraint which, if not enacted, will result in an undue hardship.
4. The proposed modification does not compromise safety, function, appearance and maintainability based upon sound engineering and technical judgment.
5. The modification is not in conflict with land use requirements.

170.1.3 Review

1. Type I modifications shall include, but not be limited to, geometric design and the modification or omission of standard roadway cross section elements.  A Type 1 modification requires a higher level of scrutiny than a Type II modification.
2. Type II modifications shall include, but not be limited to, sight distance, access spacing, number of accesses, intersection angle, etc. 
3. The request to modify design standards shall be reviewed first by Engineering technical staff who shall make one of the following decisions:
4. Approve as proposed,
5. Approve with changes, or
6. Deny with an explanation.
7. Design Modification approval shall not constitute a precedent for use at other locations.

170.1.4 Appeal

Applicants may appeal the Engineering technical staff's decision to the Transportation Engineering Manager.  The Transportation Engineering Manager's decision may be appealed to the Road Official, whose decision shall be final.

170.2 ADA Exceptions

The County has adopted the PROWAG standards for ADA accessibility within the public rights-of-way and easements under the jurisdiction of Clackamas County. PROWAG provides justifications for exceptions to the standards for new construction and for alterations to existing ADA accessibility features. Exceptions are required for any accessibility feature that cannot meet the requirements due to a physical constraint identified in the following sections.  Crosswalk closures are also reviewed under the ADA exceptions process.

170.2.1 Exceptions for New ADA Accessibility Features

Exceptions to full compliance with PROWAG standards can only be granted for a limited number of physical constraints preventing full compliance. If an exception is required for a particular feature, efforts must be made to ensure that other elements are accessible. Exceptions for non-compliance with the PROWAG standards for new ADA accessibility features can only be approved when full compliance cannot be achieved due to terrain or historic features. Where the State Historic Preservation Officer or Advisory Council on Historic Preservation determines that compliance with a requirement would threaten or destroy historically significant features of a qualified historic facility, compliance shall be required to the extent that it does not threaten or destroy historically significant features of the facility (PROWAG R202.3.4).

170.2.2 Exceptions for Alterations to Existing ADA Accessibility Features

Where existing physical constraints make it impracticable for altered facilities to fully comply with the ADA requirements, compliance is required within the scope of the project. Existing physical constraints include, but are not limited to, underlying terrain, right-of-way availability, underground structures, adjacent developed facilities, drainage, or the presence of a notable natural or historic feature (PROWAG R202.3.1). 

170.2.3 ADA Exception Request Submittal

1. Exception requests shall be submitted on the ADA Exception Request form.  Exception requests should only be submitted at the following points in the process:
2. Requests for exceptions to waive the requirement for a new ADA accessibility feature as part of a development should be submitted and acted upon prior to land use approval since land use conditions are typically written with little or no flexibility.
3. Requests for exceptions to requirements for a particular element should be submitted during plan review and must be acted upon prior to permit issuance.
4. Requests for exceptions to requirements may be submitted during construction if physical constraints are identified that were not included in the design. In such situations, the project Engineer shall prepare a revised design that maintains accessibility to the greatest extent practicable, and that exception must be acted upon prior to construction of the accessibility feature.
5. Exceptions should not be provided for noncompliant features after construction.
6. Exception requests that are submitted shall be reviewed by Engineering.  The Transportation Engineering Manager will make the decision to approve or deny the requested exception. The Transportation Engineering Manager's decision may be appealed to the Road Official, whose decision shall be final.

160.1 Requirement for Public Easement

As a condition of approval for a development, the County may require that additional road right-of-way or other public easements be dedicated in support of the proposed development to meet standard cross sectional elements.  The determination of the right-of-way and easement widths and types will be made upon review of the development with the requirements for dedications identified via land use requirements or as identified in the dedication review processes. 

160.2 County Approval Required

State law and County policy require evidence of County approval before a dedication instrument of a public easement can be recorded per ORS 92.014.

160.3 Development Permit Required

A Development Permit is required to ensure County acceptance of any required improvements with a dedication.

160.4 Minimum Width Requirements for Rights-of-Way and Easements

Definition of standard road right-of-way widths by roadway functional classification are provided in Standard Drawings C110 to C140.  However, there are special districts and projects that require road designs specific to those areas.  Details specific to these areas can be found in the Comprehensive Plan.

1. In the case of the requirement to dedicate a Permanent Public Utility Easement (PUE) or combination of another easement that includes a PUE, an eight (8) foot wide easement along the entire abutting right-of-way of all front lot lines.  It should be noted that storm and sanitary lines are not permitted within a PUE.
2. Additional easements for signing, slopes, and pedestrian facilities may be required via land use requirements or during construction plan review.

160.5 Public Easement Dedication Process

1. Typical easements that may be required for dedication by plat or by a separate instrument (standard easement form) may include, but are not limited to:
   1. Permanent Right-of-way Easement for Road Purposes
   2. Permanent Public Utility Easement
   3. Permanent Sign, Slope, Public Utility and Sidewalk Easement
   4. Permanent Storm Drainage Easement
2. Depending upon the requirements of the project, one or more of the above easement dedications may be required.  
3. In addition to the aforementioned easements, an applicant may be required to provide proof of recorded access from a public road through the proposed development to an abutting parcel as noted in Section 220.2.

If proof of said access easement cannot be proved or has not previously been created, then an applicant will be required to dedicate a permanent for the benefit of the abutting parcel on the face of the plat.  If created by separate document, this form may be obtained from Engineering and reference the process below in Section 160.8.

160.6 Dedication of Public Right-of-Way and Easements On the Plat

1. Dedications of right-of-way and easements on a plat shall meet all requirements of Sections 160.1 through 160.5.
2. Dedications of easements shall be shown on the plat and meet the requirements of the ZDO.

160.7 Dedication of Public Right-of-Way and Easements Outside of the Plat

1. Dedication of right-of-way and easements created by separate document outside of the plat shall follow Sections 160.1 through 160.5.
2. Easement dedications that are required to allow for development should be acquired and recorded prior to issuance of a Development Permit.
3. Prior to acceptance of right-of-way or public easements, plans may be reviewed by the DTD Planning and Zoning Division to determine if a land use approval is required.  The design and construction of the resultant roadway may proceed pursuant to the requirements of these Standards and in conformance with all applicable land use conditions.
4. The easement forms are available for use from Engineering.
5. When requested by Engineering, each easement shall be accompanied by an appropriate Exhibit "A" and "B."  Exhibit "A" is the written legal description of the easement area, and Exhibit "B" is the map depicting the area of the legal description.   Both exhibits shall be stamped and signed by a Land Surveyor.
6. If the applicant's representative has not previously provided Exhibits "A" and "B" to the County, Engineering can provide copies of previously recorded exhibits that were acceptable to the County.
7. The applicant will be asked to provide documentation supporting the easement signer's authority to execute land rights documents on behalf of the corporation or other representative organization.  The applicant may also be required to provide a copy of the owner's current vesting deed.
8. Easement forms, with exhibits, shall be submitted to Engineering for review and approval, prior to obtaining signatures on the easement forms.
9. Acceptance and recording of documents will be provided free of charge by the County.
