In compliance with Section 1462.04, a sediment control plan for a proposed development area, with maps drawn to a scale of one inch equals twenty feet, shall be submitted to the City Engineer and shall contain the following information:
(a) Location of the area and its relation to its general surroundings, including, but not limited to:
(1) Off-site areas susceptible to sediment deposits or to erosion caused by accelerated runoff; and
(2) Off-site areas affecting potential accelerated runoff and erosion control;
(b) Existing topography of the development area and adjacent land within 100 feet of the boundaries. A topographic map should contain an appropriate contour interval to clearly portray the conformation and drainage pattern of the area.
(c) The location of existing buildings, structures, utilities, water bodies, drainage facilities, vegetative cover, paved areas (streets, roads, driveways, sidewalks, etc.) and other significant natural or man-made features on the development area and on adjacent land within 100 feet of the boundaries;
(d) A general description of the predominant soil types, their location and their limitations for the proposed use;
(e) The proposed use of the development area, including present development and ultimate utilization, with detail on soil cover, both vegetative and impervious;
(f) All proposed earth disturbances, including:
(1) Areas of excavation, grading and filling.
(2) The finished grade, stated in feet horizontal to feet vertical, of cut and fill slopes.
(3) Kinds of utilities and proposed areas of installation.
(4) Proposed paved and covered areas in square feet or to scale on a plan map.
(5) Makeup of proposed surface soil (upper six inches) on areas not covered by buildings, structures or pavement. Description shall be in such terms as original surface soil, subsoil, sandy, heavy clay, stony, etc.
(6) Proposed kind of cover on areas not covered by buildings, structures or pavement. Description shall be in such terms as lawn, turfgrass, shrubbery, trees, forest cover, rip-rap, mulch, etc.
(g) Provisions for temporary and permanent erosion control;
(h) Provisions for the management of storm water, derived both on-site and from upper watershed areas, including the control of accelerated on-site runoff, to a stable receiving outlet;
(i) Provisions for maintenance of control facilities, including easements to ensure short as well as long-term erosion and sediment pollution control and storm water management;
(j) Proposed construction sequence and time schedule for all earth disturbing activities and installation of provisions for erosion and storm water management;
(k) Design computations and applicable assumptions for all structural measures for erosion and sediment pollution control and water management. Volume and velocity of flow must be given for all surface water conveyance. This information shall also be provided for surface water outlets.
(l) Seeding mixtures and rates, lime and fertilizer application rates, and kind and quantity of mulching for both temporary and permanent vegetative control measures;
(m) Estimate of costs of erosion and sediment control and water management structures and features;
(n) Title, scale, direction, legend and date of all plan maps;
(o) Names and addresses of the person(s) preparing the plan, the owner and the person responsible for the development area;
(p) Certification that all earth-disturbance, construction and development will be done pursuant to the plan.
The City Engineer may waive specific requirements for plan detail or may require additional information to show that work will conform to basic requirements of this chapter.
