Arterial and collector roads with the lowest net condition rating for sewer, water, road, trees, sidewalks, street lights, traffic signals are entered on our Infrastructure Replacement List and discussed at Internal and External Utilities Coordinating Committee meetings. Once assessments have been completed, priorities are based on the following:
In 2013, 54% of London roads were rated Good to Very Good. In comparasin to other Cities in Southwestern Ontario, London fits right in the middle of percent averages.
We use a PQI (Pavement Quality Index) rating scale from 1-100 in a 4 year repeating cycle, in combination with sewer and water video inspections.
On average, 15-20 kilometers a year of sewers and watermain are trenchlessly lined in London. These trenchless programs allow for the deferral and avoidance of large capital costs and the minimization of social impact by avoiding open cut construction.
