And don't forget Anthony Eden's 1/400 - surface water! So what is the right answer? I guess of better information, I'll just take an average of all these slopes. (discarding the value for sewage runoff. At least I hope sewage drainage from the sundial doesn't become an issue!) So, The List's average recommended minimum slope for sundial drainage is: 1/130 (or .76%). John John L. Carmichael Jr. Sundial Sculptures 925 E.
