706.03.07 Fertilizing and Seeding. Use spreaders, drills, or other approved machinery. Hydroseeders shall not be used to apply seed or fertilizer.
Apply fertilizer and seed after preparing soil. Seeders shall be capable of uniformly placing seed and fertilizer at the specified rate. Calibrate equipment before application.
Apply materials accurately and uniformly to avoid misses and overlaps. Do not operate machinery during windy weather that may interfere with uniform application.

When it is not possible to perform the Inspection, Final Acceptance will be delayed until Inspection is possible.
The Inspection Report will be included in the Punch List requirements for the project. Complete the Punch List requirements as directed.
Final Acceptance will be granted after all operations have been completed, and when shrub seedlings and other permanent seeded species have grown at least 4 in. tall, exhibit dark green color, and are at least 95 percent groundcover.
706.04 MEASUREMENT AND PAYMENT.
