A. The ASTM for 12” SDR-35 should be ASTM D3034. Amendment includes correction for specification.

12. We have reached out for quotes on the Grass Seed to several Native Seed Specialist. One of which has been in the business for 20+ years and did not want to provide a quote because he believed this planting will quickly become a solid mat of grass and reminded him of an “old school design from 15+ years ago.” We thought that Amendment 05 might have changed the Seed specification, but it did not. Based on this information we are concerned that the seedings will just result in matted grass. Is the USDA aware of this concern? Has the seeding plan been verified by a native seeding specialist within the USDA?
