41110 -- 1 7 - NE D 3 : 1 4 Y•1Fi I EF: = TELJART r. ASc C _ F _ 1 0 Mr. Steve Rohlf March 16, 1993 Page Two Council including the sedimentation pond. DNR and C of E permits probably are not required for the sedimentation pond; however, a conditional use permit may be required based on the City's Flood Plain ordinance. 8. The grading plan shows development elevations for only Phase 1. Soil borings indicating water table and/or mottled soil elevations are necessary to review the development plan. The plan shows some home sites with only 2.5 feet difference from front to back. It is unclear what type of home this indicates. 9. The developer has petitioned for utility and street improvements. This petition will not be considered by the City Council until they review the preliminary plat. City sanitary sewer and water will access the site from the trunk facilities located in Orono Road at the southwest corner • for the City Hall site. The route from the existing utilities to the proposed plat is along Fresno and through Orono Lake 3rd Addition. It is recommended the water system also be looped either to the intersection of Main Street and Orono Road, or back to the trunk line within Orono Road. Also, provisions need to be made to loop the water in the cul-de-sacs internal to the plat. Easements will need to be provided for this work. The entire first phase can be served by gravity sanitary sewer. However, future phases fall off toward the river; therefore, a lift station will be required with future phases. 10. The storm sewer internal to this development needs to be oversized to provide capacity of the area north of CSAH 30. 11. Riverview Drive is shown connecting to the existing Riverview Drive in Palmer's 1st Addition. This connection makes sense for continuity in the City street system. - 12. The preliminary plat shows six cul-de-sacs. Overall, however, the plat has a reasonable traffic pattern. By connecting roads, it would be possible to eliminate five of the six cul-dc-sacs. These cul-de-sacs are desirable to the developer, but cause problems for snow removal and other maintenance activities. It is recommended that all cul-de-sacs be provided with a properly located "bank" of mailboxes and paper boxes to eliminate one for the snow plowing problems.
