• 17. A 2.0 -foot minimum cover over all storm sewer i e is required. PP q Ravens Hollow Review Page 4 June 30, 2003 City of Lino Lakes, Minnesota 13. All drainage from this site falls within the drainage area of Baldwin Lake in accordance with the City's Surface Water Management Plan. The majority of the site's drainage is proposed to flow to the southeast part of the site, and into a wetland that extends into the property to the south. The 100 -year elevation of the wetland, as well as the 100 -year elevations proposed for the development site ponding, must clearly be shown to assure that water does not exceed or overtop Ware Road. All emergency overflow locations and elevations must also be clearly shown to assure that proposed housing elevations are safely above projected flood levels. 14. The proposed pond along Ware Road (at the rear of Lots 3, 4, and 5) appears to discharge to a Wetland along Ware Road. The wetland outlet and emergency overflows are not defined or identified on the plan. 15. It is assumed that the legend and grading notes on Sheet 2 correspond to Sheet 1. As part of standard practice, such notes are typically provided on the same sheet. It is suggested the notes either be shown on Sheet 1, or referenced accordingly. 16. Sheet 1 is very cluttered with numbers and details over much of the plan (too close to each other or on top of each other), thus making it difficult to fully review. The plan must be cleaned up in order to be acceptable. 18. The following notes must be added or revised as follows: • A note shall be added, stating that any fill material, topsoil, or soils imported to the site must be approved by the City Engineer. The source of the material must also be provided to the City Engineer. • An additional note must be added stating that all permit requirements of the RCWD must be adhered to. • All grading shall be confined to the property. No additional runoff from the site shall enter upon neighboring properties. If grading requires any work into the adjoining property, the Contractor shall be responsible for attaining authorization as needed. • The proposed backyard draining of many of the house units, particularly along the north, south, and west sides of the property must be addressed further to assure that additional drainage is not being added to neighboring properties. Utility Plan • 1. The plan proposes connecting an 8 -inch water pipe to an existing 12 -inch line at Linda Lane. Further review by the City should be conducted to verify that further extension of the 12 -inch size into or through the property is not needed.
