STREET OPENING PERMITS & PAVEMENT RESTORATION REQUIREMENTS
Administrative Rule Adopted by Bureau of Transportation Engineering & Development Pursuant to Rule-Making Authority
Portland’s Office of Transportation issues revocable permits to open the street for installation of underground utilities as described in Title and Chapter 17.24. Certain requirements for cutting into the pavement and restoration of the pavement have been established and included in the Standard Construction Specifications Manual. The administrative rule below establishes specific requirements that are not included in the Standard Construction Specifications Manual or in City Code Title 17.
II. Administrative Rule
1. Trench Cut Requirements – The actual trench cut will follow the new standard t-cut, with a minimum of 6" overlap on each side of the trench for base replacement. On 5-year moratorium streets, additional pavement restoration will extend beyond the limits of the trench and t-cut. The permiittee will be required to required to remove the AC and replace to the dimensions outlined below or as directed by the City Engineer. In most cases, full width base replacement in the T-Cut area may not be necessary.
2. Lateral Cut Requirements – These are generally used to cut into a pre-existing facility to allow for a single connection and may include full street width crossings. Most lateral cut requests on 5-year moratorium streets may be handled through the standard street opening procedure. The City Standard Construction Specifications using a T-cut apply but the replacement requirements vary:
- On arterial streets where the lateral impacts a travel lane, replacement shall be a minimum of five feet (5’) on each side of the trench.
- On arterial streets where the lateral impacts only the parking lane, replacement shall be a minimum of three feet (3’) on each side of the trench.
- On local streets, replacement shall be a minimum of three feet (3’) on each side of the trench.
In any case, the patch shall be extended to the nearest lane line or street centerline.
3. Longitudinal Cuts – These cuts generally run length-wise in the roadway. Most longitudinal cut requests on a 5-year moratorium street will require an expanded permit process as outlined in this rule and will be handled by the Permit Engineering Section. The extent of the surface pavement replacement width will depend on the location of the longitudinal run in relationship to parking, bike and travel lanes. Generally, requirements are as follows:
- A single lane that is impacted shall have full pavement restoration for the width of the lane.
- If multiple lanes are impacted, the full width of all lanes affected shall be restored. Given the location and the extent of the trench repair, consideration may be give for restoration only to the center of a lane(s).
- Impacted bike lanes shall be restored in their entirety.
