The storm sewer pipe between CBMH 301 and FES 300 shall be adjusted such that future maintenance would not encroach upon the adjacent private property. 4. Several structures are shown at or below minimum cover (CBMH 101; CBMH 114; CBMH 115; CB 204; CBMH 301; CBMH 302). Verify with the final construction plan submittal that all storm sewer pipe has a minimum 2 feet cover which includes the pipe thickness. 5. The type of storm sewer pipe is not labeled on the plans and shall be reinforced concrete pipe per City standards. TRANSPORTATION 1. A Traffic Study was prepared by SRF Consulting Group, dated May 9, 2016. The following comment/questions should be addressed. • The analysis documents an issue with the backup of traffic southbound on Hodgson Road turning left onto Birch Street. It is indicated that this backup is more than 400 feet which will impact the southbound through traffic creating a potential safety concern with stopped traffic in the through lane. Existing crash data should be reviewed to determine if an issue exists? It was further indicated that signal timing improvements would help elevate the issue now and in the future with the proposed site traffic. This analysis should be completed documenting the improvement and impacts to other approaches, if any. • In the "Neighborhood Impacts" section the traffic volume increases show ranges on each roadway. We recommend using the actual estimates. The traffic volume figures show actual estimates. Showing the increase in the AM and PM peak hour volumes should also be included. • More clarification should be provided in the "Neighborhood Impacts" section. This should include documentation of what a typical residential street should/would look like including examples of other streets with similar traffic volumes and characteristics. 2. The site plan shows a loop street configuration north of the intersection where northbound Sioux Lane turns west to Hokah Drive. A WB — 53 truck turning template should be provided to insure that they can maneuver around the street configuration. It is recommended that this area is required to be maintained by a Home Owners Association. 3. An emergency vehicle access / trail is shown from the end of the cul-de-sac through Outlot E that connects to the existing trail on the north side of Birch Street south of the development. The trail connection in the cul-de-sac is next to the proposed driveway to lot 23. The location and design of the connection should be completed to insure that it is SACommonity Development\ProjectsTlanning Cases\St. Clair Estates\Staff Reports\20160608 PZ (PP-Varlance)\t 20160602 Engineering Review Lino Lakes -Si
