Findings & Decision: Rohan Real Estate Investments (PT 21-18) December 2021 8 EC 9.6792 Stormwater Quality - In order to reduce runoff pollution and mitigate the volume, duration, time of concentration and rate of stormwater runoff from the development, the applicant must select, size, and locate infiltration or filtration type stormwater quality facilities from the Stormwater Management Manual to treat the stormwater runoff from the shared driveway. The Stormwater Quality standards at EC 9.6792(3) apply to all land use applications submitted after March 1, 2014. Because the proposed partition does not include the construction of public streets, private streets or new shared driveways, it is specifically subject to the Stormwater Quality Standard at EC 9.6792(3)(a), which requires that the applicant submit a site plan that delineates the areas on the site that have infiltration rates less than 2 inches per hour, bedrock less than 5 feet below ground surface, groundwater elevations less than 6 feet or ground surface slopes greater than 10%. The “Soil Data” notes in the application provide the information required by this standard. The standards of EC 9.6793 through EC 9.6796 do not apply because the proposed development is at an elevation less than 500 feet, it does not drain directly into a headwaters stream, it does not generate high concentrations of oil and grease and does not include any specific pollutants of concern identified in EC 9.6795(2). EC 9.6797 Stormwater – Operation and Maintenance – These standards apply to all facilities designed and constructed in accordance with the stormwater development standards. This section also specifies when and under what conditions the public will accept functional maintenance. The applicant proposes private operation and maintenance of the on-site stormwater management facilities. For the applicant’s information, an operation and maintenance plan consistent with the City’s Stormwater Management Manual requirements shall be reviewed and notice of this plan will be recorded during the building permit process. Based on the above findings and future permit requirements, the stormwater development standards are met. (k) All other applicable development standards for features explicitly included in the application. The existing buildings on Parcel 1 will comply with applicable development standards as shown on the applicant’s tentative partition plan. The subject property is within the /CAS Commercial Airport Safety Overlay Zone and is subject to the provisions of EC 9.4130. Its current building heights for remaining structures and other characteristics comply with the standards of this Code section. Any new development on the subject property will be required to meet the requirements of EC 9.4130. It is noted that future development on the proposed parcels will be subject to further review for compliance with applicable standards, including but not limited to residential development standards in EC 9.2750.
