Gaffron Senior Plannirg Coordinator City of Orono Post Office Box 66 Crystal Bay, MN 55323 Re: Waade Subdivision File No. 139-2329 Dear Mike: We have reviewed the sketch plan for the proposed three to four lot Waade subdivision. The site is located at 3280 and 3290 Northshore Drive (C.R. 51) east of Tonkawa RoadfC.R. 135) in the southeast quarter of Section 8. We have the following comments in regards to engineering matters. 1. Access: The private road on Outlot A does not meet the minimum width, design speed or right- of-way for a private road as outlined in the City Ordinance. The private road currently serves 4 homes and potentially would serve 7 or 8 homes. No more than two units may be serv'ed from a private driveway. Private streets serving three to seven units must be paved 24 feet wide, more than seven units require 28 feet. Due to the existing house locations it would be impossible to meet all of the code requirements. We recommend a minimum pavement width of 24 feet and minimum right-of-way width of 50 feet across Outlot A. The two driveways shown to serve the site should be combined to form a single driveway at least 20 feet in width. The proposed pavement at Unit No. 2 should be enlarged to allow for emergency vehicle turning movements. The fire department should review the plans and provide comments. Plans should be submitted to Hennepin County for their review. 2. Utilities: The proposed easterly realignment of the sanitary sewer falls within 6 feet of an existing home. The proposed alignment may need to be shifted westerly to allow tor construction. The existing overhead power may need to be relocated to allow for construction. Utility construction plans should be submitted for review. 3. Grading: A grading and erosion control plan for the entire site should be submitted for review. Erosion control measures should be in place prior to any grading, particularly along the lakeshore. Additional erosion control will be needed during construction of the houses and septic systems. 4. Drainage: The draft version of the City ’s’ Comprehensive Stonn Water Management Plan (SWMP) shows that the site lies witliin the Maxwell Bay drainage districts. The entire site
