It contained fourteen (14) Conditions of Approval. Outlined below, you will find the City’s Conditions in Italic and the applicant’s response to each of those Conditions in regular text. 1. The applicant will obtain all required permits and inspections for the using (of) the existing sewer connection to the building as required by the City of Springfield Plumbing Code. Response: This will be done at Building Permit phase and with the connection to the sewer. 2. Prior to approval of the Final Site Plan, the applicant must provide an operations and maintenance plan to the City for review to ensure the long-term maintenance and operation of the proposed storm filter catch basin, consistent with maintenance criteria required by EDSPM 3.03.1. The plan must designate maintenance responsibility for operating and maintaining the system and must be distributed to all property owners and tenants of the site. Response: The draft O & M Plan has been generated and is being submitted with this application. See attachment 5a. 3. Prior to Final Site Plan approval, the applicant must provide calculations showing the entire parking lot area is being pretreated and/or vegetatively treated with adequately sized treatment areas. Response: See attachment 5B Stormwater Memo. The infiltration basins will be fully vegetated prior to final inspection. See note on the plans. 4.

Response: The elevator is an existing part of the building and as such does not have a floor drain. The use was discussed with staff and the elevator is existing and to retrofit with a sanitary drain would be costly and disruptive to the foundation. Also, staff has pointed out that the site is not within any applicable TOTZ, therefore a sanitary drain will not be required. See attachment 5C, an email from staff dated May 22, 2024. 5. The developer must place all existing overhead power and communication services underground from the existing pole to the building at a location to be determined in cooperation with SUB electric and the telecom service provider.

The purpose of this document is to address the need for the site to meet stormwater quality requirements outlined in comments received during the Development Initiation Meeting on June 20, 2023, and Site Plan Review comments received on April 2, 2024. This document will discuss these comments and establish compliance with the City of Springfield Development Code. Water Quality Proposal Springfield Code 4.3.110 requires any development that creates or replaces 5,000 square feet or more of impervious surface area to install storm water controls consistent with the Engineering Design Standards and Procedures Manual (EDSP, December 13, 2012). Furthermore, EDSP 3.02.5 states that 100 percent of parking lots and paved areas be pre-treated for stormwater quality, and 3.02.6 requires 50 percent of the non-rooftop impervious area on site to be treated using vegetative methods. The total non-rooftop impervious area includes approximately 13,000 square feet of parking, 5,000 square feet of walkways, and 1,300 square feet of existing asphalt concrete to remain. This totals 19,300 square feet of area, or 9,650 square feet of impervious runoff area that requires vegetative treatment. To address these requirements, a section of the parking lot on the east side of the building can be regraded and the runoff directed to two stormwater planters. As-builts of the area indicate a stormwater main to the east of the site running north to south, and is likely where an existing catch basin on the subject site makes a connection to the public system. The two proposed DIGITALLY SIGNED planters would replace the catch basin and can overflow to the main after water quality requirements have been met. This parking lot totals approximately 8,200 square feet of impervious area runoff directed to vegetative treatment via the planters. In addition to this parking lot area, walkways on the south and west side of the structure drain to landscape away from the building. This runoff would sheet flow through grass landscape, and provide additional vegetative treatment as the landscape would act as a filter strip. These walkways include 1,800 square feet of impervious area, totaling approximately 10,000 square feet of non-rooftop impervious area that would receive vegetative treatment. For the remainder of of the site, the contractor will need to inspect all existing catch basins designated to remain, as well as TV inspect existing stormwater pipe and replace or repair as necessary. Catch basin filter inserts will need to be installed in existing catch basins, providing mechanical treatment for the remaining impervious areas. This brings the site into compliance with the Springfield code as defined above. Stormwater calculations and analysis performed by Branch Engineering, Inc. utilized HydroCAD 10.00 modeling software using the Santa Barabara Unit Hydrograph hydraulic modeling method. The results of this analysis are attached. 24-Hour Rainfall depths are based on City of Springfield Engineering Design Standards & Procedures Manual. Conclusion With the information provided in this Stormwater Document and the attached calculations, the proposed development has been designed in accordance with the City of Springfield requirements for water quality.

I will be sure to note that change once the Final Site Plan comes in for review, as I am sure you will in your response.

Please do not click on links or open attachments unless you know the content is safe. |** Kelly, Condition #4 notes that the elevator shaft must have a solid floor with a sanitary drain. However I believe this is based on an assumption that we are adding this elevator - when it actually already exists and we aren’t planning to modify it. I’m linking the 1980 elevator drawings here for reference: https://www.dropbox.com/scl/fi/2rvblslgbc7hw6zliy6b2/1980_04-08_Elevator- Addition.pdf?rlkey=nixordhpvhbws9jv0vh7zzi2t&dl=0 I’m hoping/assuming that we don’t need to retrofit a sanitary drain, but please let me know.
