Unpaved Alleys

In the unpaved alley maintenance program, we currently maintain 1,095 blocks of maintained alleys. Our routine scheduled unpaved alley maintenance is an ongoing operation starting in late March or early April and continuing through November. During this time, most of our alleys are inspected and graded approximately twice. However, the frequency of grading varies, depending on the grade of an alley, the volume of traffic that uses the alley, the occurrence of rainfall, the amount and intensity. Adding all of these factors it becomes our second operational procedure, a service request. Usually a service request is from one of the abutting property owners and is handled through an inspection by a section supervisor or manager. Once the location is inspected and conditions warrant maintenance, a grader is sent out. This is usually within a week from the time of request. Grading and rocking requests can be made by calling Street Maintenance, Engineering Services, or by going on-line to the City of Lincoln web site.

Whether it is routine maintenance or a service request to grade an alley, it is normally graded in the same manner. The operator loosens the surface material with his cutting blade. Once the material is loose the operator works it from side to side filling all voids and reestablishing a smooth and drainable surface. On occasion it becomes necessary to add fill material, usually clay dirt or asphalt grindings. When adding this material, the operator will wind-row the surface material to one side, place the clay or asphalt grindings where they are needed, then proceed with re-establishing the finished surface.

In our alley maintenance program, we also provide ¾" limestone rock at a minimal cost to adjoining property owners. Rock can be added any time during the season, either to the entire alley or areas adjacent to individual lots. A standard 300' alley needing a 1 ½" to 2" cover will require approximately five ton for each 50'. The price for rock to property owners is determined by an annual bid for granule material, which is handled through the Purchasing Department. Property owners can pay either individually or collectively, however payment is required prior to placement. The City absorbs the additional cost, trucking and spreading, in our Streets and Highways budget.

The City also has numerous platted unimproved alleys throughout the community. Most of these alleys have little or no travel on them and serve primarily as a common access between adjoining properties. There are measures in which existing platted unimproved alleys can become a maintained alley in the Lincoln Municipal Code under Section 14.20.020 PDF Document. One or more of the adjoining property owners can petition the City for a grading and graveling district which must be approved by the City Council. The work is then done by a private contractor and the costs are normally assessed to the benefitting properties. After the work has been inspected and approved by the City Engineering Services staff, the location is added to our maintenance list.

One final note on unpaved alleys. Whether it's a maintained or unmaintained alley, as long as its platted, the abutting property owners may petition to have an alley vacated. To do this it requires 100% of the property owners approval and their willingness to purchase the section of alley behind their property. When vacated, the alleys are usually split down the centerline and are subject to retaining easements for existing or planned utilities. Vacation of an alley must be approved by the Planning Commission and the City Council.
