Name: Corrin Wendell Date: October 7, 2022 Page: 3 H:\Heidi\Planning\Planning Cases\1415 - Lennar - Final Plat 1st addition Variance Rezoning - Paul Tabone\City Engineer Comments Review Memo 10.6.docx Overall Site Plan • All keynotes – update the detail plate callouts to match detail plate number and associated sheet number. • Note F – maintain 6’ sidewalk width around power pole for plowing purposes. • Note I – the City now has a standard detail for these park benches on concrete slabs. Reference detail. • Note J – given there are driveways proposed on Vanderbie Street near Street 1, this curb could be surmountable to allow more flexibility in where the driveway goes. If you have a very strong plan for the driveway location and want to stick with B618, add a note that curb cuts should be staked and installed at driveway locations. • Note M – permanent barricades should be installed at First Addition limits w/ future road extension signs until roads are extended with future additions. WSB can provide a detail for this (Woodbury has a good detail). • Note O – due to its nature as a mid-block crossing, we have previously talked about an enhanced crossing. Please include RRFB signs at this crossing. On that note, include an overall signing plan for the First Addition. • Is there a reason the trail cannot be installed east of Vanderbie Street as part of the First Addition? Additionally, is there a reason the trail cannot be installed south of Desoto Street as part of the First Addition? This would provide First Addition residents with trail access to Thunder Bay Park (and associated trail) and Pioneer Park. Mass Grading, Drainage, & Erosion Control Plan • The grading plan scale, text size, and number of notes makes it very difficult to review the grading plan, follow contours, review storm sewer, etc.. A larger scale version of the grading plan would benefit all project stakeholders. Please modify accordingly. Grading will be re- reviewed with updates submittal. • Label EOF elevations for local low points within the site. Also show nearest LFE to local low points. Example: STCB-5126, unlabeled structure near BL 29 LOT 1 (sheet number unlabeled but is likely CG-103. • The erosion control blanket hatching is very hard to see. Please modify the linetype so that it is visible. Grading Notes • Note 14 under grading notes section – 6” of topsoil should be provided in non-paved areas. Storm Sewer Structure Table • Several flared ends are completely submerged as they discharge into ponds. There appears to be vertical clearance to raise pipes so that inverts are at or just below pond NWL’s. Please revise. • Ensure public catch basins and manholes have castings R-3067 and R-1733, respectively. Storm and sanitary per detail STO-8. Any public boulevard drains should be beehive style R-4342.
