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. [LDC 25-8, Subchapter A, Article 7, Division 4; ECM 1.4.4] The revegetation line item quantity must equal the entire LOC area less any existing impervious cover proposed to remain and less proposed public streets and sidewalks. This is necessary in the event that construction ceases after vegetation has been removed from within the LOC.

This reviewer can review proposed note language. PARD / Planning & Design Review - Thomas Rowlinson - 512-974-9372 PR 1: The Southeast Travis County MUD No. 1 Consent Agreement and PUD ordinance 20160616-041 requires 51.49 acres of parkland. To comply with Exhibit D of the PUD ordinance, PARD requires that acreage numbers be provided as broken out in Exhibit D of the PUD. Calculations show acreage of Lot 76, Block K as unencumbered, despite including floodplain. Please update the table to comply with the parkland acreage categories to demonstrate compliance with the PUD parkland requirements. PR 2: On park Lot 76, Block K, define all the boundaries of the drainage easement, the water quality easement, and the PUE separately, so that the only label on the lot is “Greenbelt/Open Space.” While the easements may be allowed and not tracked against acreage in floodplain, defining the easements areas is required so that park areas are not at risk of being lost by “blanket” easements. The Legal Department requires separate documents to record each easement and for each easement to be delineated on the plat. PR 3: To demonstrate compliance with parkland requirements under the PUD ordinance, please rename the lots to be dedicated parkland as “Greenbelt/Open Space” and delineate easements, 25-Year Floodplain, 100-Year Floodplain, water quality/detention ponds, and CWQZ. PR 4: Once acreage categories have been finalized in accordance with the parkland requirements of the PUD (see PR 1) please add to note 26 to include: This final plat includes XX acres of parks and open space land, bringing the total acreage for MUD #1 to XX acres.
