These rates should be <br /> doubled if seed is broadcast and should be increased by 50 percent if the seeding is done using a Brillion Drill or is applied <br /> through hydraulic seeding. Hydraulic seeding may be substituted for drilling only where slopes are steeper than 3:1. If <br /> hydraulic seeding is used,hydraulic mulching should be done as a separate operation. <br /> b See Table TS/PS-3 for seeding dates. <br /> ' If site is to be irrigated,the transition turf seed rates should be doubled. <br /> d Crested wheatgrass should not be used on slopes steeper than 6H to IV. <br /> ' Can substitute 0.5 lbs PLS of blue grama for the 2.0 lbs PLS of Vaughn sideoats grama. <br /> June 2012 Urban Drainage and Flood Control District TS/PS-5 <br /> Urban Storm Drainage Criteria Manual Volume 3 <br />
