Construction Specifications

Any permit for construction along County right of way must follow these specifications:

General
1. To obtain a permit to work in Dakota County right of way, the owner(s) of facilities placed in the right of way and the contractor(s) working on those facilities must be registered and have a certificate of insurance on file with Dakota County.

2. Except as otherwise permitted, construction work on County highway right of way shall not commence until an application for a Permit has been made and such Permit granted. The Permit sketch shall show the location of the proposed construction work with reference to county highway centerline and highway right of way line. The proper right of way width should be indicated. A copy of the sketch shall be provided for each copy of such Permit.

3. Burning or disking operations and/or the use of chemicals to control or kill trees, brush and other vegetation is prohibited without prior approval from the County.

4. Waterways and drainage lines shall remain operative at all times.

5. Prior to removal of any existing turf, all necessary Erosion Control Devices shall be in place. Wherever topsoil and/or sod are disturbed they shall be replaced within a maximum of SEVEN days or in accordance with the NPDES permit - if applicable, and maintained satisfactorily until the new turf is established. In addition, all work shall be in compliance with local, state and federal regulations.

6. Wherever topsoil and sod are disturbed they shall be replaced and maintained for one year until the turf is established. When seeding, some type of mulch must be applied.

7. The utility facility and installation shall not interfere with any existing utility facilities on the County highway right of way.

8. When necessary, barricades, warning devices and flagmen shall be provided by the Utility during all phases of their construction and maintenance operations on County highway right of way. The design and placement of all signs, barricades, and other warning devices shall conform to the current Minnesota Manual on Uniform Traffic Control Devices.

9. At the time of construction of the utility and at the times of subsequent maintenance, prior approval must be obtained from the County Transportation Department for the cutting and trimming of trees within the county highway right of way. Wherever trees are cut the resulting stumps shall be removed unless otherwise provided in the Special Provisions of the Permit. Any holes caused by stump removal shall be backfilled, are leveled and all materials associated therewith disposed of outside the county highway right of way. The utility shall advise the County Transportation Department at least 48 hours in advance of its intent to start clearing and grubbing operations.

10. Upon completion of an excavation, the County Transportation Department shall be notified within 5 working days so that a final inspection can be made to determine its acceptability.

11. If it appears that this project will require work within the traveled portion of the roadway or shoulder, the Permittee must submit a traffic management plan a long with the permit application. This plan should incorporate whatever signs and/or flagman the Contractor will be required to utilize and the Contractors proposed work operation as it affects traffic on the County Road. This plan must be approved at least 24 hours in advance of any work in the roadway. A minimum of ten day prior notification is required if a detour is needed. The permittee must also notify and coordinate this work with local police and fire departments. No lane closures are permitted during rush hour time from: 6 a.m. to 8:30 a.m. and from 3:30 p.m. to 6 p.m. without prior approval in the following cities: Apple Valley, Burnsville, Eagan, Farmington, Hastings, Inver Grove Heights, Lakeville, Mendota, Mendota Heights, Rosemount, South St. Paul, Sunfish Lake and West St. Paul.

12. The County shall not be responsible for damages to an irrigation system from highway maintenance or signing activities or any other cause. The applicant agrees not to operate the sprinkling system during frost or freezing conditions when over spray would cause ice conditions on the roadways or sidewalks and will suspend sprinkling when pedestrian activity is present.

13. Winter season requirements for working on Dakota County highway right-of-ways start in the fall once the ambient temperature drops below freezing, and continues until the temperature warms and stays above freezing in the spring. This is typically between Nov. 1 and April 15, although the actual dates may vary based on weather conditions.

During the winter season, no excavations will be allowed in paved road surfaces unless a permanent hot bituminous repair or a temporary patch using concrete or other hot asphalt product, can be made. Temporary patches must be replaced with a permanent hot bituminous repair in the spring. Cold mix patches are not approved, except for emergency repairs. Emergency repairs include: water main or gas main leaks, faulty telecommunication or power cables, sewer line repairs, etc… Cold mix patches are the responsibility of the permittee and must be monitored and maintained by someone 24 hours a day until a permanent or approved temporary patch is made.

Snow removal may be required for work off the roadway. Snow can be relocated back away from the road to other areas of the right of way, but can’t be pushed or blown onto private property without the property owner’s permission. Snow may be trucked off site, provided the proper traffic control is set up. Any snow and ice dropped onto the roadway must be scraped off and road salt applied. Sidewalks and trails must be closed during any snow removal or construction activity in the blvd and then cleared and reopened once the work is completed.

Except for emergency repairs, no construction activity, parked vehicles or equipment will be allowed within the roadway including the shoulder up to the curb during periods of inclement weather, or if inclement weather is imminent. Freezing rain, sleet and snow create slipper road conditions and poor visibility. These conditions make work zones dangerous for both the traveling public and contractor personal.

Any construction work during the winter season must be approved by the County prior to the start of a project. The decision on whether or not a project can commence shall be at the discretion of the County Right-of-way Manager. During the winter season, daily permission may be needed from the County Permits Office prior to working in the County right-of-way as weather conditions change. At the time of inspection the County right-of-way manager may order the immediate cessation and possible correction of any work which poses a threat to the life, health, safety or well being of the public and/or the people performing the work. As always, the correct traffic control device layout is required when anyone is working in the right of way.

All restoration, including turf and trail damage, must be promptly restored in the spring. All turf restoration shall be made with sod or black dirt, seed and mulch of some type covering the seed. By state statute, the excavator is responsible for plantings and turf establishment for up to one year.

14. No foreign material such as dirt, gravel or bituminous material shall be left or deposited on the road during the construction of access or installation of drainage facilities. Roadside must be cleaned up after work is completed.

15. After all construction work is completed, the permittee shall notify the Dakota County Transportation Department for a final inspection within 5 business days.

Aerial
1. There shall be only a single pole line on the County highway right of way on either side of the center line thereof.

2. Longitudinal installations on County highways shall normally be located in the outer five feet of the right of way. At crossings of the County highway, poles shall be placed at a minimum of thirty feet from the shoulder lines of the through roadbeds unless right of way widths are prohibitive to such location.

3. The location of all brace poles, anchors and anchor poles within the limits of the County highway right of way shall be approved by the County Transportation Department.

4. In those instances in which a Utility is issued a Permit or Permits for construction on both sides of the County highway right of way in a given area, such Permit is conditioned upon the Utility subsequently providing joint use to other Utilities upon reasonable terms mutually agreeable to the Utilities.

The bore pits shall be restricted to the area from five feet beyond the shoulder of the road except as modified in the Special Provisions of the Permit.

2. All voids caused by jacking or boring shall be filled by pressure grouting. The grout material can be a Bentonite or a sand-cement slurry of at least two sacks of cement per cubic yard and a minimum of water to assure satisfactory placement.

3. The underground utilities shall be so installed to preclude any necessity for disturbing the roadbeds to perform maintenance operations.

4. Underground installations shall be accomplished without damaging or destroying the principal root structure of trees.
