Evel�n M. Turner From: Evelyn M. Turner Sent: Monday, November 23, 2009 12:45 PM To: 'jsonnek@charlescudd.com' Subject: additional information -2400 Fox engineering comments and grading for Mr. Robinson's lot next door John: In Darren's comment letter the words "culvert under" are missing from the 4th bullet point. We will have public works inspect it right away so the City's work can coordinate with yours. Here's the code section referenced in the 5th bullet point: (2) For all subdivisions and commercial or industrial sites in which land disturbance activities will impact one or more acres; or fill or excavate over 100 cubic yards, whichever is more restrictive; or any other site if determined appropriate by the city Engineer due to potential impacts to wetlands, lakes, or sensitive receiving waters. a. Grading plan. A grading plan shall be provided that clearly indicates the proposed land disturbance activities. Both existing and proposed topography shall be shown and have a maximum contour interval of two feet. Drainage patterns shall be clearly shown using arrows depicting direction of flow. Other information shall be shown as required by the city based on specific project characteristics. b. Phasing plan. A phasing plan shall be provided that clearly indicates the areas in the order they are to be disturbed and restored. The phasing plan shall consider minimization of area and duration of exposed soil and unstable conditions, minimization of the disturbance of natural soil cover and vegetation, erosion and sediment control measure installation, weather conditions and the schedule for temporary and permanent restoration. The area and duration of each phase shall be indicated on the plan. c. Pond defail sheet. A pond detail sheet shall be provided for each proposed stormwater pond that shows detailed pond design including normal water level, high water level, aquatic bench, maintenance bench, outlet structures, emergency overflow locations and other project specific data required by the city. d. Standard detail sheet. A standard detail sheet shall be provided that consists of applicable construction details for approved erosion and sediment control measures as developed by the city. Other techniques may be used upon prior approval by the city with details provided by the designer. e. Specifications. Written specifications for land disturbance activities such as product descriptions, installation and maintenance procedures required by the applicant to carry out the project in accordance with this chapter. f. Stormwater pollution prevention plan as required under the NPDES stormwater permit issued by the MPCA. The stormwater pollution prevention plan shall consist of three components: (i) Temporary erosion and sediment control plan: Indicate the location of perimeter controls, construction fence, temporary sedimentation basins, inlet protection, areas to be seeded, areas to be mulched or blanketed, location of construction waste control (dumpsters, chemical storage, concrete washout, portable restroom facilities, etc.) and all other required temporary erosion and sediment control measures as described in section 79-9. This plan shall also indicate staging of temporary erosion control measures. (ii) Permanent erosion and sediment control plan: Indicates areas to be seeded and sodded, sediment ponds, storm sewer systems and all other required permanent erosion and sediment control measures. Permanent stormwater pollution controls including, but not limited to ponds, vegetated buffers and structural measures shall be designed and constructed in accordance with other chapters of the city Code and requirements of other agencies having jurisdiction. (iii) Narrative: Describes, at a minimum, the nature of construction activity, person(s) responsible for inspection and maintenance of site erosion and sediment control including i
