1615 Ringer Subdivision <br />page 5 <br />Lot 6, Block 1 <br />Peres PB61 thru PB66. Borings BB61 thru BB63. Average perc <br />rates at both sites are acceptable. Slopes range from 2 to 48. <br />Mottling started at a depth of approximately 2.4 feet, with <br />actual water level at 2.5 to 4.41. A standard mound system <br />should be used at both sites. <br />Lot 7, Block 1 <br />Peres PB71 thru PB76. Borings BB71 thru BB73. Slopes average 2-3%. <br />Perc rates were fairly slow, with the secondary si.ce being somewhat <br />slower than the limit (however, the justification for Lot 5, <br />Block 1 also applies here). Actual water level ranged from 1.7 <br />to 3.5' with mottling generally below 2.5'. A standard mound is <br />recommended for both sites. <br />Lot 1, Block 2 <br />Peres PA11 thru PA18. Borings BAll thru BA13. Slopes are very <br />flat. Mottling was indicated below 2.2 ' with actual water <br />encountered below 2.01. Two secondary sites were tested. All <br />sites are acceptable for a standard mound system. <br />Lot 2, Block 2 <br />Peres PA21 thru PA26. Borings BA21 thru BA23. very flat slopes. <br />Mottling occurs at 2.0 to 2.4' with actual water encountered <br />below 2.41. Perc rates on both sites are acceptable. A mound <br />system is recommended for both sites. <br />Lot 31 Block 2 <br />Peres PA31 thru PA36. Borings BA31 thru BA33. Slopes averaged <br />2 to 51. Mottling starts at a depth of 2.0-3.51. Actual water <br />level was below 2.5'. Perc rates are acceptable. Mound systems <br />are recommended for both sites. <br />Lot 4, Block 2 <br />Peres PA41 thru PA46. Borings BA41 thru BA43. Slopes are very <br />flat. Mottling generally was found below 2.01, with actual <br />water level at abu ut 4.01. Perc rate for primary site is <br />acceptable; perc rate for secondary site iL slightly slow but <br />acceptable for a mound based on the justification referred to <br />for Lot 5 Block 1. I recommend a mound system for both sites. <br />Lot 5, Block 2 <br />Peres PA51 thru PA56. Borings BA51 thru BA53. Slopes are very <br />flat. Mottling occurred below 1.2 feet with actual water below <br />4.0 feet. Perc rates are acceptable for the primary site and <br />slightly slow at the secondary site. (Refer to Lot 5, Block 1) <br />This lot has the overall worst set of percolation rates of the <br />division. 'However, only two of the peres were taken in the <br />topsoil, the others, two of which were very slow, 4ere at depth. <br />I recommend that a mound system be used on this site. If peres <br />were re -taken in the topsoil, it is likely they would pass as <br />did nearly all others done in this manner. <br />
