The contractor is required by contract to repair all disturbed areas once work is completed. Seeding and mulch will also be used in the Right of Way. If permanent seeding can’t be completed within the seeding dates specified in the contract, then temporary erosion control measures (hydromulch) will be used until permanent seeding can be completed.  Permanent seeding dates are scheduled to take place citywide during two separate intervals: April 15 to June 15 and August 10 to October 15.
