** Special geologic feature buffer widths are as follows: |
Low buffer is less than 50 feet |
Medium buffer is 50 feet to 100 feet |
High buffer is greater than 100 feet |
*** Rates greater than 500% not recommended |
**** Assumes adequately permeable soils and lack of natural constraints as required for all infiltration systems. |
1 Infiltration systems may be allowed at the determination of the engineer and/or geologist, provided that a detailed site investigation is undertaken which confirms nature of rock, location of special geologic features, and adequacy of the buffer between the SGF and the proposed stormwater system(s) |
2 In these special geologic features: low buffer situations, infiltration systems may be allowed at the determination of the engineer and/or geologist, provided that a detailed site investigation is undertaken and a 25-foot buffer from SGFs is maintained |
