A conceptual ESC plan is necessary to assess the accuracy of the ESC fiscal estimate. ESC fiscal surety must be posted with the City of Austin prior to Plat approval. Additional fiscal posting might be required at the time of subdivision construction plan ESC review. Sites with a limit of construction greater than one acre must include a $3000 per acre LOC clean- up fee in the fiscal estimate. [LDC 25-8, Subchapter A, Article 5; ECM Appendix S-1] Sites with a limit of construction greater than 25 acres are required to show phasing of disturbance tailored to the specific site conditions. A phased ESC plan and phased fiscal estimate are required.

The flow rates can be considered equal if the developed rate is no more than one-half (0.5) cfs greater than the existing rate or if the developed rate is no more than one-half (0.5) percent greater than the existing rate and there are no existing erosion problems downstream of the site” (LDC 25-7-61).
