Enclosed items include one (1) copy of the current Stormwater Report for reference, two (2) Minor Modification applications with attached Coastal Piedmont Developers, LLC annual filings, and two (2) new High Density Deed Restriction forms with attached tables. 1 understand that no new application fee is associated with this modification. As a summary, the developer wishes to re -allocate the allotted allowable BUA for the lots in this subdivision to those amounts shown in the table. Phases One and Two (Lots 1-33, 58-60) have previously been platted, so these lots' allowable BUAs will not be impacted. However, Phases Three and Four will be re -allocated. Three lots (62-64) have been lost due to septic unsuitability. Additionally, lots 73-74 will have their allowable BUA's reduced. The net total of impervious area being contributed by the lots, however, will remain the same as original at 328,000 sf. After approval, the developer will modify the restrictive covenances accordingly to reflect the proposed. Please review and let me know if you have any questions, comments, or require any additional information.

After the wet detention pond is established, it should be inspected once a month and within 24 hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal County).

An incomplete submittal package will result in a request for additional information. This will delay final review and approval of the project. Initial in the space provided to indicate the following design requirements have been met. If the applicant has designated an agent, the agent may initial below. If a requirement has not been met, attach justification. Requded Item: Initial Page or plan sheet number and any notes: 1. Plans (1' - 50' or larger) of the entire site showing: - Design at ultimate build -out, - Off -site drainage (if applicable), - Delineated drainage basins (include Rational C coefficient per basin), - Forebay (if applicable), - High Flow bypass system, - Maintenance access, - Proposed drainage easement and public right of way (ROW), and - Boundaries of drainage easement. 2. Plan details (1' = 30' or larger) for the level spreader showing: - Forebay (if applicable), - High Flow bypass system, - One foot topo lines between the level lip and top of stream bank, - Proposed drainage easement, and - Design at ultimate build -out 3.
