Where broadcasting is necessary or preferred, rates will <br />double.Note: (*) = Trace. Some houses will not mix less than 0.1#. Since species availability may vary, <br />the operator may substitute species of similar utility. The species described are therefore subject to change <br />without revision to the permit. Regreen is a substitute for the use of mulch, providing live stabilization that <br />will die out within three years as the native grasses begin to express themselves. The overall mixture is <br />intended to provide ample genetic potential over highly variable soils with a reasoned mix of height, form, <br />color, function (bunch and sod forming), and season (cool and warm season). Costs used two sources which <br />will vary by season and availability; and, where cost was not available, a reasonable estimate was given <br />based upon comparable species. <br />Varra Companies, Inc.
