➢ If suitable soils exist on the site, underground infiltration systems (e.g., infiltration trenches) or surface storm water infiltration systems (e.g., splash blocks, pervious pavers, or surface ponding areas and/or swales) may be used to avoid creating hydraulically-connected impervious area from a storm water detention standpoint. Section 3-2.2 of the City's Stormwater Management Manual lists site and design criteria that must be met. ➢ From a storm water detention standpoint, for an impervious area to be considered hydraulically- disconnected, storm water runoff from the 100-year, 24-hour storm must be fully retained and/or infiltrated — without resulting in significant potential for adverse effects from the infiltrated water (such as slope saturation or migration to crawlspaces and/or basements). However, if the on-site soils cannot support fiill intiltration of the 100-year, 24-hour storm, partial infiltration may still be feasible to meet allowable storin water release requirements. 21. All storm water facilities shall be designed in accordance with applicable City standards and/or design policies. 22. Per City policies due to the proximity of the site to environmentally sensitive areas, seasonal limitations may be placed on land alteration activities. Land alteration activities are defined in the City's Desi�n and Construction Standards and Specifications as clearing, grubbing, excavation, filling, grading, and stockpiling. Determination of the exact seasonal limitation period requires site- specific information generally not available until the project design stage. However, preliminary analysis using the information available at this time indicates that land alteration activities on the project site may be restricted to the period between April 1 and October 1. 23. All chemicals or products of a hazardous or toxic nature that may be used or stored on the site must be stored under cover and isolated from the storm drainage system. 24. If vehicles or equipment will be washed and/or steam cleaned on this site, a designated wash area must be provided for these activities. The area must be covered, paved with Portland cement concrete, hydraulically isolated from the storm drainage system, and must drain to the sanitary sewer through a baffle-type oil/water separator. A discharge authorization from the City's Industrial Pretreatment Prograin may be required for the connection to the sanitary sewer. Wastewater from washing operations inay not be discharged to the storm system. 25. Table 1-5.7 of the City's Stormwater Management Manual contains an error in the"n" values for sheet flow. The column of values should read "0.011, 0.05, 0.15, 0.24, 0.41, 0.13, 0.40, 0.80". 26. Parking must be per City Zoning Code and City Design and Construction Standards and Specifications. For the 26,801 square feet of manufacturing space, a minimum of 45 parking spaces must be provided. 27. A pedestrian circulation system for the site must be approved by the Planning Director and Traffic Engineer prioi-to the isst�ance of any building permits. Walkways must allow pedestrians and wheelchairs to gain easy access from sidewalks and bus stops to building entrances through the use of paths which are physically separated from vehicle traff ic and maneuvering areas. (See the city's Design and Consti•t�ction Standards and Specifications Manual and Section 39.165 of the Zoning Code.) // / /
