CSG RESPONSE: There is no hatch for swales. What you're seeing is a combination of <br />topographical contours and erosion control blanket. Language for callouts revised and Legends <br />revised for clarification to sheet C3.1. Only contours shown on side slopes, with erosion control <br />blanket hatch removed, and language added for clarification. <br />- Add proposed contour labels. Call out proposed slope <br />CSG RESPONSE: Sheet C3.1 revised to show contour labels. <br />- Swale outlet at Pond is 861,which is higher than discharge from FES 860.23, water will not flow <br />towards pond. <br />CSG RESPONSE: Swale mentioned above has been removed. <br />- western 2 swales are virtually flat grade from outlets to pond, are they intended to act as infiltration? <br />CSG RESPONSE: One of the two is being removed. The other is there to act as a temporary <br />outlet for the city pond prior to the completion of construction by the city. The NWL of the pond <br />is proposed at a 861, and the location we were instructed to end the outlet is at the CB in <br />Sundwood drive with an IE of 859.99, so the swale is designed to the best of our ability to <br />provide the action the city is requesting. <br />Sheet C4.0 <br />- Extend Sewer and Watermain stubs 10 feet beyond back of curb. Mark with Carsonite markers, green <br />for sewer, blue for water. Stubs must be parallel to future road alignment. <br />CSG RESPONSE: Per conversations with the City of Ramsey we are showing correct stub <br />lengths and locations. To the northwest following the future road alignment as well as straight <br />to the north for the future park development to the North East of West Ramsey Parkway. <br />- Public street design requires calculation of spread at each catch basin. Spread cannot exceed <br />MNDOT guidelines. Plan and profile sheets are required for all public streets, with sewer and water on <br />a separate sheet from storm sewer. Sewer and water must be shown on street and storm sewer in a <br />screened pen. All storm sewer in public right of way must be designed for 100 year storm in keeping <br />with regional ponding plan for the COR area. <br />CSG RESPONSE: Plan and profile to be completed after street and utility alignments are <br />approved in this submittal. <br />Storm sewer is sized for the 10 years storm and EOF route protection provided for the 100 year <br />storm. This will be adequate to provide flood protection and adequate storm sewer capacity. <br />- Verify Pipe will have minimum 3 fps flow at full capacity. Typical minimum slope for 42in. pipe is <br />0.0007 ft/ft. <br />CSG RESPONSE: Storm sewer alignment and sizing revised per revised reports, see sheet C4.0 <br />- Depressed median requires impermeable liner and drain tile connected to storm sewer. <br />CSG RESPONSE: Sheet C4.0 revised to show correct proposed depressed median design per <br />typical section provided by Bolton Menk. Detail 1/C5.4 added. <br />- New gate valve may be installed for testing purposes. The new valve shall be full opened after testing <br />and abandoned in place. <br />CSG RESPONSE: Sheet C4.0 revised accordingly <br />4931 West 35th Street • Suite 200 • St. Louis Park • Minnesota 55416 www.civilsitegroup.com <br />Matt Pavek, PE • 763-213-3944 Patrick Sarver, PLA 952-250-2003 <br />
