Depth to seasonal water table (gray mottling or gray color) X No Yes inches 5. Free water present X No Yes range in inches Niev6. Soil percolation rate estimated X Yes Texture group I Q III IV No Estimated rate Mc min/inch 7. Permeability test performed Yes 419 X No 1\01``\ If yes, note type of test performed and attach X Site Approved: Drainfield to be placed at 48" depth at site designated on permit. Site Disapproved: Reasons for rejection: 1. Position in landscape subject to flooding or periodic saturation. 2. Insufficient depth of suitable soil over hard rock. 3. Insufficient depth of suitable soil to seansonal water table. 4. Rates of absorption too slow. 5. Insufficient area of acceptable soil for required drainfield, and/or Reverse Area. 6. Proposed system too close to well. 7. Other Specify (attach additional pages if necessary) � �- q - Abbreviated Design Form This form is for use with gravity,pump to gravity,enhanced flow,and low pressure distribution(LPD)sewage system designs and when applying for a certification letter or subdivision approval. This abbreviated design covers the E!primary and reserve area, 0 only the primary area, 0 only the reserve area(check one)for South Ivy Phase 2-Residue(Property ID). Design Basis Total length of available area: 90' Total width of available area: 120' Estimated Perc.

No (Yes/No) Effluent quality required: Primary (Primary, Secondary,Advanced Secondary) Square feet per bedroom: 344 Total trench bottom area required: VL 3ooB ,Z7 �ll�li1 Area Calculations Number of trenches 12 Length of trenches: 90' Width of trenches: 3' Center to center spacing:_ 9' Reserve required? Yes Percent reserve area required: 100 Total width of absorption area required 102' Total trench bottom area provided: 3240 The required width is calculated by multiplying the center-to-center spacing by one less than the number of trenches and adding 1 trench width plus any required reserve area. If the topography is not uniform across the length of the site the trenches will need to flare apart on one end to maintain contour. When this occurs it is necessary to use a center-to-center spacing that accounts for the flair or the installer will not be able to fit the system within the approved area. It is perfectly acceptable to have more area available,especially up and down the slope,than is required.
