It ispreferable that the construction record drawing be prepared by someone other than the designer. Please do not provide design drawings as construction recorddrawings.A.A signed and dated professional seal of the preparing engineer or surveyor.B.The name and address of the firm and individual preparing the drawings on the title sheet.C.The constructed location of all items associated with each facility, and the inspection records to verify proper dimensions, materials and installation. The items include, but are not limitedto the following:1.Inspection Records and photographs for pipe trenches and bedding, including underdrains.2.Video Pipe Inspection for any pipes which are not accessible or viewable.3.Updated Location with geo-coordinates of all facilities.4.Verified Drainage Area maps for the drainage area treated, and for drainage to the facilities.5.Current physical and topographic survey for all earthen structures. Ponds should include a survey of the pond bottom. Surveys should verify pond volumes are per design. Correctionsmay be required for alterations from the design.6.Plants, location and type.7.Plans and profiles for all culverts, Pipes, Risers, Weirs and Drainage Structures - Display the installed type of drainage structures, culvert/pipe size, weirs, materials, inlets or endtreatment(s), inlet and outlet protection, alignment and invert elevations compared to design.8.Computations: For significant deviations from design, provide sealed computations verifying that the as-built condition is equivalent or better than design.9.Ditch Lines - Display the constructed location of all ditch lines and channels, including typical sections and linings.10.Easements - Show all platted easements with dead book references labeled. Facilities and drainage must be within platted easements. Provide copies of recorded documents.11.Guardrail, fences or other safety provisions - Display the constructed location of all safety provisions; fences, guardrail, including the type, length and applied end treatments, comparedto design.12.Material layers - biofilter media, stone layers, sand layers, keyways and cores must be verified as to material types and depths. Include inspection reports, boring or test pit reports andmaterials certifications. Biofilter media must be an approved state mix.13.Access roads - show location of access roads, surface treatment, drainage, etc, as applicable.14.Compaction reports are required to verify fill compaction in dams.15.Manufacturers certifications for proprietary BMP's certifying proper installation and functioning.DA-N 1-YearDA-N 10-YearDA-O 1-YearDA-O 10-YearDA-N 1-Year RoutedDA-N 10-Year RoutedDA-N Routed & DA-O Combined 1-YearDA-N Routed & DA-0 Combined 10-YearDA-B 1-YearDA-B 10-YearNON & O Combined676775756262 DA-L0.65 AcPRE DEVELOPMENT DRAINAGE AREAC-622POST DEVELOPMENT DRAINAGE AREADA-C 1-YearDA-C 10-YearDA-P 1-YearDA-P 10-YearP C-623LIMITS OF VRRM STORM WATER QUALITY CALCULATIONSSOILS MAP C-630RECORDED & VACATED DRAINAGE EASEMENTS NEW DRAINAGE EASEMENTSLEGENDDBDEED BOOKPGPAGEFHFIRE HYDRANTWVWATER VALVEWMWATER METERFFEFINISHED FLOOR ELEVATIONUFEUPPER FINISHED FLOOR ELEVATIONBSLBUILDING SETBACK LINEPSLPARKING SETBACK LINEPP POWER POLESCCSTORMWATER CONVEYANCE CHANNELWPWALL PACKULDULTIMATE LIMITS OF DISTURBANCETPTREE PROTECTION FENCINGVARIABLE WIDTH FOREST AND OPEN SPACE EASEMENT C-631RECORDED & VACATED FOREST & OPEN SPACE EASEMENTS NEW ACCESS EASEMENT PLATLEGENDDBDEED BOOKPGPAGEFHFIRE HYDRANTWVWATER VALVEWMWATER METERFFEFINISHED FLOOR ELEVATIONUFEUPPER FINISHED FLOOR ELEVATIONBSLBUILDING SETBACK LINEPSLPARKING SETBACK LINEPP POWER POLESCCSTORMWATER CONVEYANCE CHANNELWPWALL PACKULDULTIMATE LIMITS OF DISTURBANCETPTREE PROTECTION FENCINGVARIABLE WIDTH FOREST AND OPEN SPACE EASEMENT
