Contractor shall provide routine sweeping of arterial (major), collector, commercial, and residential streets, as indicated by the street listing which is included in Exhibit 2 – Street Listing and Initial Route Map. Contractor will be provided with initial route map indicating the sweeping cycle located in Exhibit 2. Contractor is encouraged to develop their own routing if greater efficiency can be achieved. Any route changes proposed by Contractor must be submitted in writing and approved by the City Representative prior to new route implementation. Standard operating hours for routine sweeping under this agreement shall commence Sunday evening and conclude Thursday morning. Routine sweeping operations shall not begin prior to 6:00 p.m. and must be completed by 6:30 a.m. Contractor shall develop a schedule within the time constraints and submit it in writing for approval by the City Representative. Routine scheduled sweeping is based on a rotating 4-week cycle and has no correlation to the week of the month in which it falls. For example, if the contract begins on October 10th, 2019, the week 1 sweeping would begin on October 13th, week 2 begins on October 20th, week 3 begins on October 27th, week 4 begins on November 3rd. The cycle would begin again with November 10th as week 1.
