PA • Section 4.2.27 (Watershed Protection Overlay Districts) • Section 6.23.3 (Stormwater Infiltration and Detention) • Article 22 (Definitions) Application of the text amendments will result in changes to the Watershed Protection Overlay District boundary depicted on the official Zoning Atlas and on the Land Use Element Map of the 2030 Comprehensive Plan. The proposed text changes in "Track Changes" format are included in Attachments 1 and 2. BACKGROUND: The BOCC authorized staff to proceed with this item at the August 2009 Quarterly Public Hearing (non - public hearing portion of the agenda) and it was discussed at the October 13, 2009 BOCC work session. Changes to the "Critical Area" of the Upper Eno watershed is one of the higher priority items to accomplish further implementation of the Efland- Mebane Small Area Plan which calls for a re- evaluation of the Critical Area boundary for Seven Mile Creek. This item was heard at the February 22, 2010 Quarterly Public Hearing (QPH). The abstracts for the QPH and March and April Planning Board meetings are provided as Attachment 10. These previous abstracts include significant Background information that would be redundant and space- consuming to include again here. Revisions Since Quarterly Public Hearing There have been small changes to the documents and maps since the February 22 Quarterly Public Hearing as appropriate comments received during the public input process were incorporated into the proposed amendments. The maps contained in Attachment 3 reflect the current proposal. The specific changes that have occurred since the QPH are: • Section 4.2.27 — The last bullet on page 2 (lower right corner) of the section was added to exclude the land area north of the centerline of West Ten Road and west of the centerline of the Interstate 85 /US 70 Connector from the County- designated critical area (see Attachment 3.1 for location) • Section 4.2.27 — Language was added to the sixth bullet on page 2 (lower right corner) of the section to clarify that the intent of continuing the critical area designation in an "isolated area" within the overall critical area boundary is to provide a greater level of protection for an area that drains to protected streams. • Section 4.2.27 — Table on page 3 (lower right corner) of the section. The source of elevation data was added. • Section 6.23.3 — page 10 (lower right corner) of the section. A sliding scale for impervious surface ratios was added specifically for the Upper Eno (had previously been covered by the existing scale on the left of the page which will now apply only to University Lake, Cane Creek, and Little River). This change was discussed at the QPH, but the scale was not available at the QPH. Letters Received from Other Agencies On March 18, 2010, the Town of Hillsborough sent the County a letter supporting the continued protection of the Town's drinking water supplies through the proposed Critical Area amendments. Additionally, the Orange - Alamance Water System (OAWS) sent a letter on March 30 expressing appreciation to Planning Director Craig Benedict for a presentation made on the
