Francis Street_EngineeringFrom: Hailey Guglielmo Sent: Friday, June 4, 2021 9:16 AM To: Sarah Yoon Subject: RE: HPC Referral (Courtesy Review): 135 W. Francis Street Engineering Comments are as follows: 1. Applicant will be required to follow the requirements of a major development within the Urban Runoff Management Plan. The conceptual HPC plan shows the installation of a water quality vault to account for stormwater requirements. The plans show an infiltration vault to accommodate the WQCV within 10’ of two property lines. Infiltration vaults must follow the same guidelines as drywells. Drywells must be 10' from property corners. If there are no alternatives a variance is required to allow an infiltration vault within 10' of the property lines. The variance shall address proper separation from the hydrant so as not to cause freezing issues. 2. The plans show a transformer across the alley. Does this transformer serve the property and does the existing transformer have capacity for the increased use? Will this property require a new transformer? Work with the City Electric Department to determine available capacity. A Load Calc Form will be required at time of building permit. 3. The conceptual plans show a new water service line. At building permit also show abandonment of the existing line. Verify if the structure will have a fire suppression system and call out water service line size. If a 2” is requested provide a memo from the fire suppression company stating a smaller line size will not provide adequate flows. 4. Excavation for the proposed water quality vault must be examined with the Engineering and Parks Departments. No excavation will be allowed within the ROW or the tree drip lines of the large trees in the vicinity. 5. Application calls out the historic building to be relocated for excavation. What is the proposed system for stabilization? At building permit, provide excavation and stabilization plans. Include information on how the structure will be supported. Thanks.
