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.

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.
