Ms. Katie Larsen 09/04/2025 Page 5 13.The City minimum storm sewer size for public roads is 15” and must be RCP. Include storm sewer pipe material on utilities sheets. a.Pipe from ST-108A to ST-108 must be increased to 15” diameter. ISG Response (7/14/2025) – Storm Sewer within roadway has been updated to be a minimum of 15”. WSB Response (8/6/2025) – Comment addressed. 14.Structure types and sizes should be called out for Wilkinson Way storm sewer. ISG Response (7/14/2025) – Structure Types and Sizes for sewer within Wilkinson way have been added to the plans. WSB Response (8/6/2025) – Comment addressed. 15.Show storm sewer in profile view along Wilkinson Way to ensure there are no utility conflicts. a.Utility crossings should be checked across the site to ensure there are no conflicts and to call out insulation as needed. ISG Response (7/14/2025) – Storm Sewer has been added to the profile of Wilkinson Way on the Final Plans. WSB Response (8/6/2025) – Comment addressed. No conflicts appear to be present and insulation is called out in storm profile view. 16.Ensure structure diameters are sized properly for alignments with pipes at acute angles or with large diameter pipes. ISG Response (7/14/2025) – Storm Structure diameters were updated. WSB Response (8/6/2025) – Check constructability of structures with large diameter (>21”) pipes. For example, ST-202 with a 36” RCP and 42” RCP at 90° is not likely constructable as a 48” structure. WSB Response (9/4/2025) – Remains an open comment even though pipes into ST- 202 have changed. 17.What is the purpose for structure ST-2? ISG Response (7/14/2025) – ST-2 was removed per grading updates. WSB Response (8/6/2025) – Comment addressed. 18.How will the low points at driveways into Buildings A and B be drained? ISG Response (7/14/2025) – Trench drains were added to the utility drawing. WSB Response (8/6/2025) – Comment addressed. 19.Indicate tip-out gutter as needed to ensure pooling is avoided in upgradient portions of parking lots. ISG Response (7/14/2025) – Reverse curb gutter callouts have been added to the plans. WSB Response (8/6/2025) – Comment addressed. 20.ST-304 should be moved to the corner of the nearest parking stall rather than on the curb radius. ISG Response (7/14/2025) – ST-304 was moved to the end of the nearest parking stall. WSB Response (8/6/2025) – Comment addressed. 21.It is recommended to route ST-201 directly to FES-4A to avoid daylighting drainage and potentially flooding onto the proposed trail. ISG Response (6/9/2025) – Storm Sewer was updated to convey stormwater directly to the basin. WSB Response (6/20/2025) – Comment addressed. 22.The OCS details on sheet C0-26 do not match HydroCAD modeling. ISG Response (6/9/2025) - Detail has been updated to match the HydroCAD modeling. WSB Response (6/20/2025) – The weir wall is modeled as 5’, though the detail shows a 6’ diameter structure.
