Public Works: Operations
The Street Maintenance Program maintains the public streets of Springfield in the best possible condition, free from defects and safety hazards, while providing the most cost-effective maintenance techniques for all City streets. This program provides the manpower and equipment to maintain all City streets, including those of concrete, asphalt, chip seal, and gravel construction. Planned services include, but are not limited to: pot hole patching, spot surface repairs, asphalt overlays, street cut repairs, repair of sub-base, gravel street maintenance, curb and gutter repair/installation, shoulder repair, street evaluations, stockpiling, guardrail repair/installation, street sweeping, and work for other departments. Included in this program are snow and ice removal and storm damage repairs. During the winter months, personnel are scheduled 24 hours per day, as needed, to insure the safest possible travel conditions. The Street Division also responds to emergency calls as situations merit.
The Drainage Maintenance Program ensures drainage systems on public rights-of-way and improved drainage systems accepted by the City are free of uncontrolled growth and blockages. This program provides the manpower and equipment needed to keep the water flowing through our ditches ,drain tiles, and bridges. Included among the activities performed are: cleaning and reshaping of drainage ditches, removing of silt and debris from drop inlets, power washing of blocked driveway tiles, and related repairs/construction to various concrete drainage structures. The maintenance listed above is restricted to street right-of-way and drainage easements only and is performed in order to provide needed drainage capacity and to reduce flooding incidents.
The city annually evaluates roadways and selects cost effective maintenance treatments to enhance and extend the useful life of the pavement. These treatments are tailored to produce the greatest enhancement of the street surface and generally fall into one of four categories:
- Preventive Maintenance - Preventive maintenance treatments are intended to preserve the City's asphalt roadways. The preventative maintenance treatments utilized by the City of Springfield work to extend the service life of bituminous pavements beyond the normal life expectancy of an untreated pavement. The various maintenance treatments serve to lengthen the intervals between the replacement of the deteriorated pavement. The treatment selected will depend on the age, volume of traffic, and condition of the pavement. The City of Springfield's preventive maintenance strategy is comprehensive and has proven to be an extremely cost effective way of preserving the City's infrastructure investment.
- Rehabilitation - Rehabilitation projects are used to compliment the preventive maintenance utilized by the City of Springfield. Programs in the rehabilitation category generally serve to extend the life of the infrastructure by repairing those deteriorated sections. The service life is extended by repairing and rehabilitating the existing infrastructure, and the costly replacement of that infrastructure is postponed.
- Renovation - When a pavement has deteriorated beyond the point of preventive maintenance and rehabilitation, the pavement will then need to be replaced. Pavements beyond their service life without signs of extensive roadway base failure will fall into the renovation project category. The projects in this category will receive a new surface course of asphalt and generally involve the preservation of the existing curbs and gutters. Also included in that work is the selected replacement of driveway aprons, sidewalk, the adjustment or replacement of utility frames and lids, traffic control and protection and parkway restoration.
- Reconstruction - Pavements beyond their service life showing signs of extensive roadway base failure or those requiring the complete replacement of the asphalt or concrete pavement will fall into the reconstructive project category. This is the most costly and disruptive form of roadway maintenance. These projects may also include the regrading of the roadway, complete curb and gutter replacement, extensive sidewalk and driveway replacement, and parkway restoration.
