Add to grading notes: "All grading shall conform to the City of Tucson Development Standards Chapter 11-01.0 Excavation and Grading". 5. Add the following notes to the grading plan notes: " "The approved Grading Plan is the only acceptable construction plan onsite. The Contractor may not use any other plans, such as the approved Tentative Plat and/or Development Plan, for construction purposes. The Contractor may ask the Development Services Inspector to consult with the other approved plans for additional information or details that might not be included on the approved grading plan but needed for completion of work." " "The contractor shall remove the fine materials from the bottom of the detention/retention basin and scarify the basin bottom once the construction activities are completed in order to remove any fine material build up caused by construction and to restore soil percolation." " "Any engineering work to be done below grade (i.e. toe-downs, cutoff walls, drainage pipes/structures, etc.) shall not be back filled until Development Services Inspector inspects the work and approves it." 6.

Add the basin(s) maintenance responsibility note and checklist per S.M.D.D.F.M. 2.3.1.6 C 1 and 2 to the DR. Stormwater pollution prevention plan: 1. Describe the project and its intended use after the NOT is filed (e.g. low density residential, shopping mall, Structural Practices: 2. Provide adequate sediment basins. (Part IV.D.5.a.). a. For common drainage locations that serve an area with 10 or more acres disturbed at one time, a temporary (or permanent) sediment basin that provides storage for a calculated volume of runoff from a 2 year, 24 hour storm from each disturbed acre drained, must be provided where attainable until final stabilization of the site. Where no calculation has been performed, a temporary (or permanent) sediment basin providing 3,600 cubic feet of storage per acre drained, shall be provided where attainable until final stabilization of the site. When computing the number of acres draining into a common location it is not necessary to include flows from offsite areas and flows from onsite areas that are either undisturbed or have undergone final stabilization where such flows are diverted around both the disturbed area and the sediment basin. In determining whether installing a sediment basin is attainable, the operator may consider factors such as site soils, slope, available area on site, etc. If "non-attainability" is claimed, then an explanation of that non-attainability shall be included in the SWPPP. In any event, the operator must consider public safety, especially as it relates to children, as a design factor for the sediment basin and alternative sediment controls must be used where site limitations preclude a safe design. b. For drainage locations that serve 10 or more disturbed acres at one time and where a sediment basin meeting the provision of Part IV D.5.a.1 is not attainable, smaller sediment basins and/or sediment traps shall be used. Where a sediment basin is not attainable, silt fences, vegetative buffer strips, or alternatives which achieve effective sediment control are required for all down slope boundaries of the construction area (and for those side slope boundaries deemed appropriate as dictated by individual site conditions). c. For drainage locations serving less than 10 acres, smaller sediment basins and/or sediment traps shall be used. Silt fences, vegetative buffer strips, or equivalent sediment controls are required for all down slope boundaries (and for those side slope boundaries deemed appropriate as dictated by individual site conditions) of the construction area unless a sediment basin providing storage for a calculated volume of runoff from a 2 year, 24 hour storm or 3,600 cubic feet of storage per acre drained is provided. 3. Place velocity dissipation devices at discharge locations and along the length of any outfall channel to provide a non-erosive flow velocity from the structure to a water course so that the natural physical and biological characteristics and functions are maintained and protected (e.g. no significant changes in the hydrological regime of the receiving water). (Part IV.D.5.b). Note: The velocity dissipation devices must be in place during the construction phases. Installation scheduling must be included and should be as early as practicable. 4. Replace the old ADEQ general permit with a copy of the new ADEQ general permits in the SWPPP plan. 5. Amend the SWPPP plan to include the requirements applicable to the SWPPP plan. New SWPPP requirements. OPERATOR RESPONSIBILITIES: 1. Identify who is responsible for on-site SWPPP implementation. Part III.A.2.d. 2.
