PUBLIC WORKS MEMORANDUM TO: Providence Regional Medical Center Team FROM: Sabrina Fandler, Engineering/Permit Services DATE: 3/8/2016 SUBJECT: PreApp16-006 Comments from Public Works (Engineering/Permit Services) PROPOSAL: New medical office building with parking below LOCATION: 1815 13th St The following comments have been made based on a review by the Engineering/Permit Services Division of preliminary pre-application materials for the purpose of a Pre-Application meeting only. All comments, conditions, and suggestions made below or in the Pre-Application meeting are preliminary only and may change once the project is in formal review after an application has been submitted. The following comments may only be a partial collection of notes, and additional comments may be made verbally in the Pre-Application meeting. 1. A Public Works Permit is required for this project. Detailed drawings in accordance with City Design and Construction Standards shall be submitted to the Public Works Department, showing site parking layout, landscaping, utilities, storm drainage, temporary construction erosion control, and all required improvements in the public right-of-way. Public Works Department approval of these drawings is required prior to any permits being issued. All improvements shall be completed, approved and warranted before the Occupancy Permit is issued/final approval is granted. 2. The existing water easement between the two detention ponds will need to be vacated, and a new water easement will be needed around the rerouted water lines. The new easement will need to be wide enough to provide separation from sanitary sewer and also to provide room for a replacement water main in the future. (Typically 15' total easement width, 5' on one side of the water main and 10' on the other side,measured from center of main). 3. Stormwater shall be managed in accordance with the City's 2010 Stormwater Management Manual. The pre-developed conditions should match the pre-developed conditions used when the detention ponds were designed in the master plan, as the proposed detention system will not only need to replace the detention ponds, but will also need to detain runoff from the proposed project area. Interim Policy 2-11 should have been applied to the design of the detention ponds during SEPA12-042. 4. Detention sizing will be based on matching developed discharge durations to pre-developed durations for the range of pre-developed discharge rates from 50% of the 2-year recurrence interval to the 50-year recurrence interval (per Minimum Requirement 7). If the combined sewer area has stricter requirements,they should additionally be followed. Page 1 of 2
