October 17, 2011 (Regular Meeting) <br />BUILDING SKETCH <br />STEP 1. AREA CALCULATIONS <br />Page 741 <br />A. Determine the square foot area of all the sub areas. As shown <br />on the sample card, the parcel has two sub areas: <br />BAS = 3,900 square feet <br />CAN = 900 square feet <br />B. Multiply each gross area by the percentages assigned to it <br />(this percentage is located in the TABLE OF SUB AREA found in <br />the Chapter 11 of this manual) to arrive at the effective area <br />of the building. <br />BAS 3900 SQ. FT. X 100% =3,900 <br />CAN 900 SQ. FT. X 25% = 225 <br />TOTAL EFFECTIVE AREA 4,125 <br />STEP 2. DETERMINE QUALITY INDEX (Points) <br />The determination of the quality index is a most important <br />operation. It is the discriminator allowing differences and <br />local conditions to be expressed as an index number which, when <br />applied to a general county wide rate for a given type of <br />improvement, will yield an adjusted base rate. This adjusted <br />base rate simulates the per square foot rate which the market <br />would most probably yield should that parcel sell. <br />CONSTRUCTION DETAIL <br />Foundation - 4 <br />Spread Footing 6.00 <br />Sub Floor System - 2 <br />Slab on Grade - Residential /Commercial 6.00 <br />Exterior Walls - 11 <br />SUBAREA <br />TYPE <br />GS AREA <br />% <br />EFFECTIVE <br />AREA <br />BAS <br />3,900 <br />100 <br />3,900 <br />CAN <br />900 <br />025 <br />225 <br />FIREPLACE <br />Fireplace <br />0 <br />SUBAREA TOTALS <br />1 4,800 <br />4,125 <br />Page 741 <br />A.
