For pond and ditch sizing calculations <br />see Volume III, Appendix 8. <br />2. Riprap shall consist of hard, dense, rough <br />fractured stone as nearly cubical as <br />practical. Stone shall be well graded in <br />order that the voids can be filled, and at <br />least 50 percent of the mass shall be <br />stones equal to or larger than the specified <br />riprap size. <br />3. A geotextile fabric shall be placed under <br />all riprap. Use Mirafi 60OX or equal. <br />4. Pond dewatering pipe shall be plastic <br />irrigation pipe, PIP, 80 psi rated, with bell <br />and spigot joints or glued joints, valved <br />on the outlet end. <br />5.
