Agree,there are no slopes greater than 3:1 throughout the mass grading plan.The slopes surrounding Infiltration Basin 8 are 4:1,see sheets C4.04 and C4.05 of Site Grading,Drainage & Erosion Control Plans for Miske Meadows and River Park Fourth Addition. 9. Temporary cul-de-sacs are required on all street ends. Per agreement with Engineering,all future intersecting roads with Ivanhoe Street will end at the curb radius;the only proposed temporary cul-de-sac is at the south end of Ivanhoe Street. 10. As shown this plan proposes a dead end in excess of the allowable 700-foot city standard. The new connection must be made out to County Road 40 through Miske Meadows before building will be allowed along Ivanhoe Street south of Station 15+00. Issue being worked on by Paxmar and the City regarding lots south of 15+00 once construction commences on 190th Avenue NW. Terms of such agreement will be spelled out in the Development Agreement. 11. All Emergency Overflows (EOF) must be protected with drainage and utility easements All emergency overflows are located with drainage and utility easements as indicated on the Final Plat 12. All adjacent grading in Miske Meadows effecting backyard drainage, EOFs, etc. must be completed before building construction will be allowed on the parcels in this development. PAXMAR understands that ponding and drainage needed specific to lots in question for certificate of occupancy,not building permit issuance.River Park Fourth and adjacent lots within Miske Meadows will be mass graded at the same time. All storm sewer for each block within River Park Fourth will be constructed and outleted into completed Infiltration Basins 8 or 11,or into temporary HDPE pipes to temporary sedimentation basins within Miske Meadows. 13. Provide additional detail in final plans showing intersection grades and drainage. See plan view of the Street plan and Profile sheets for curb elevations at each intersection. Additional detail may be added prior to Construction Documents. 14. Adjacent downstream utilities needed in Miske Meadows must be shown as proposed within this plan. In some instances, these are shown as existing infrastructure on this plan but those facilities are not in place nor have they been reviewed or included in approved plans. All storm sewer within River Park Fourth will be constructed and outleted into completed Infiltration Basins 8 and 11 or into temporary HDPE pipes to temporary sedimentation basins within Miske Meadows.
