Environmental: An environmental assessment has been performed during the design phase for this project. Red-winged black birds have been identified to be within the area. However, it has been noted that they migrate out of the area around September and should be clear by construction start. CCOB will obtain a second 20-day letter for the construction phase, to confirm no further environmental impacts. Construction is expected to begin within the 20-day environmental clearance.

Seeding Work: Seeding is expected to be completed within the contract working days.

However, the project may run into the season with inclement weather and inappropriate seeding season or lack of availability of seeds. The contractor is responsible for securing all the materials needed for each phase of work. If the seeding cannot be accomplished within the contract time due to the seasonal constraints, Contractor may submit a revised seeding work schedule for CCOB’s review and approval. The planting and seeding may be a delayed item of work at no additional cost to the City.
