No onsite service locations or routing is shown for utilities. All overhead utilities must be located underground. Response: All utilities are now shown on the Tentative Partition plan drawing set and will be located underground. 5. Only sanitary sewer is shown forexisting utilities, no power, telecom, water shown. Pavement limits of the street on 31" not shown, the driveway is required to be paved from the existing edge of asphalt at least 18' into parcel 2. Response: All items are now indicated on the Tentative Partition Plan drawing set. 6. While referenced in the narrative, no stormwater information presented. A report with the infiltration tests and the calculations is required. An infiltration test of 10" is claimed but only be used if the planting medium for the rain garden can be shown to infiltrate at that rate, typically this medium is 2-3 inches an hour. No grading or treatment calculations provided for the driveway. A detailed cross section and planting plan is required for the rain garden, as is an O and M agreement. This agreement and maintenance will be the sole responsibility of parcel l since it is entirely contained on parcel l and will require an easement. Response: All stormwater information, including infiltration test results, calculations, plans and detailed cross sections are attached and have been tentatively approved by Public Works. If there are any questions or concerns regarding the above Memo Items, or regarding any parts of this Tentative Subdivision application, please do not hesitate to contact me via email or by phone.
