We are looking for ideas for building a pool wall less than 3' from an existing retaining wall that will not compromise the retaining wall "angle of repose" support. We want to put in a 10'x35' shotcrete lap pool (4 shallow end - 7' deep end) in a 23'x53' courtyard area which is enclosed on three sides and open on the downslope 23' side. The 10'x35' pool will be placed lengthwise - 3' away from the retaining wall and 10' from the house wall (min. code req.). This pic conveys the idea: The 23' and 53' retaining walls are 1' thick reinforced concrete with cantilevered footings on the earth side of the wall and a footing which extends 1' on the pool side. The 23' wall is 11' tall, the 53' wall is 11' tall and slopes rapidly down to 4' continuing the length at 4'. The deep end of the pool will be next to the 4' high retaining wall section. The soil unconfined compressive strength is probably about 4K psf (type A - silty clay/sandy clay) and the soil is undisturbed. Does anyone have useful experience in this structural area? We don't need exact specs for anyone to worry about, just strategies.
