8 <br />DESIGN ALTERNATIVE TWO (2) as outlined on page fifteen (15) of the application reading as <br />follows: <br />\._ <br />`.The applicant requests a waiver from Section 2.3 Land Use Intensity-Building,. Landscaping, <br />and Site Volume Ratios' <br />The applicant is requesting that the existing composite ratio methods established within the Design <br />Manual be replaced with a `floor area ratio' and `maximum building height' limitation to control <br />land use intensity. <br />The applicant is proposing a maximum floor area ratio of point thirty (.30) and a maximum building <br />height of six (6) stories. <br />In supporting this request, the applicant has submitted the following rationale: <br />The Orange County Economic Development Manual currently employs a composite ratio <br />system to regulate the overall development of a parcel of property within an Economic <br />Development district. This ratio is comprised of the following individual elements: <br />Impervious Surface Ratio (ISR): A calculation identifying the proportion of a site <br />covered by any surface or material that impedes or prevents the natural infiltration <br />of water into the soil. Buildings, sidewalks, driveways, parl~ing/loading areas, <br />and exterior storage areas (paved and/or unpaved) are all examples of impervious <br />surfaces. <br />2. Building Volume Ratio (BVR): A calculation identifying the portion of a site <br />devoted to support a building, parking, loading, and exterior storage area intended , <br />to support a proposed land use. The formula for calculating the BVR is as C, <br />follows: <br />BVR = (VB +VP + VL + VE) / 10 <br />A <br />Where: <br />BVR =Building volume ratio <br />VB =Volume of building(s). <br />VP =Volume of parking areas <br />VL =Volume or loading areas <br />VE =Volume of exterior storage <br />A =Site or lot area <br />10 =According to the Manual, this is the constant <br />built into the formula taking into account <br />a standard building, covering an entire <br />site, that is ten (10) feet in height. <br />3. Landscape Volume Ratio (LVR): A calculation identifying the total volume of <br />trees, shrubs, buffers, and berms (either existing or installed) compared to the <br />total size of the lot being developed. The formula for calculating the LVR is as <br />follows: C <br />
