The contents of the SWPPP shall clearly demonstrate how the principles, outlined below, have been met in the design and are to be accomplished by the proposed development project.
(A) Due regard for natural drainage characteristics, topography and soils shall be indicated.
(B) To the extent possible, steep slopes shall be avoided.
(C) The grade of slopes created shall be minimized.
(D) All post-development stormwater management measures shall comply with Chapter 153 of this code of ordinances.
(E) Original boundaries, alignment and slope of watercourses within the project locus shall be preserved to the greatest extent feasible.
(F) In general, drainage shall be directed away from structures intended for human occupancy, municipal or utility use, or similar structures.
(G) All drainage provisions shall be of such a design and capacity so as to adequately handle stormwater runoff, including runoff from tributary upstream areas which may be outside the locus of the project.
(H) Drainage facilities shall be installed as early as feasible during construction and, if possible prior to site clearance.
(I) Fill located adjacent to watercourses shall be adequately protected from erosion by means of rip-rap, gabions, retaining walls, vegetative stabilization, or similar measures.
(J) Temporary vegetation and or mulching shall be used to protect bare areas and stockpiles from erosion during construction. The smallest areas feasible shall be exposed at any one time and disturbed areas shall be protected during the non-growing months, November through March.
(K) Permanent vegetation shall be planted immediately following fine grading.
(L) Trees and other existing vegetation shall be retained whenever feasible. The area within the drip line shall be fenced or roped off to protect trees from construction equipment.
(M) All areas damaged during construction shall be re-sodded, re-seeded or otherwise restored.
(N) Monitoring and maintenance inspections shall be scheduled prior to commencing the project.
(O) All controls installed or used to achieve compliance with this SWPPP must be properly operated and maintained at all times.
(P) Sediment controls, stormwater measures, and other controls shall protect downstream water bodies from adverse water quality impacts resulting form construction activities.
