The availability letter is included with the submission for 4.44 which addresses the full future site plan. 7. Got it yes, lots to do. Bond request and fee has been paid, as soon as Ana approves the contract we will wire the money for the purchase and provide proof of credits. Thanks again for your quick work! -Justin On Mar 15, 2023, at 5:06 PM, John Anderson <landerson2@albemarle.or=> wrote: Hi, Stephanie, There are additional items if project is to receive a Grading Permit with anytime to remove trees prior to NLEB TOYP, Mar-3 1: 1. Revised plan, WP0202200017 that shows ESC measures, but also incl. SWM calcs. (item 4./Note). Is this plan ready for review? 2. If tree removal only plan is ready, please send link to me. I will review tomorrow, if possible. 3. I hope to check bond estimate (.xls) sent with note, below, tomorrow /this evening, if possible. 4. Tree removal only requires water quality /phosphorus reduction —what is phosphorus reduction requirement? Provide re-dev VRRM.xls post-dev land cover table, with plan. Note: Justin has links to approved `tree removal only' plans; please see approved `tree removal' plans for level of SWM calc. detail required. • Provide VRRM.xls (water quality); re-dev .XLS • Provide water quantity narrative (see approved plans) 5. Whatever the phosphorus reduction requirement, nutrient credits must be purchased riD or to receiving a Grading Permit for tree removal. For example, using VRMM.xls re -development spreadsheet: 4.02 Ac. (pre-dev) forest, 4.02 Ac. (post-dev) managed turf, B soils, phosphorus reduction =0.19 lb. 6. Nutrient credits must be purchased from Ivy Creek nutrient bank, only, since project discharges to South Fork Rivanna River X-trib, an impaired stream. See below. 7. Note: Processes must run in parallel: a. Nutrient credit purchase, whatever the value, from Ivy Creek bank ( Note: Ana Kilmer needs to review draft bill of sale /Affidavit prior to purchase. ) b. Reach out to Ana, akilmer@albemarle.org ; reach out to Jon Roller, Ecosystem Services LLC (Ivy Creek Nutrient bank) Jon Roller Ecosystem Services, LLC (540)578-4296 c. Bond estimate request fee payment: submit via digital payment portal, $294.32 fee; identify payment is for: WP0202200017 64 W. Rio Rd. -bond estimate fee. d. WPO plan /tree removal bond once Engineering checks SE estimate, pus. work with Ana to post bond. WPO bond must be posted to receive a Grading Permit. e. Provide owner signature information ( Ana will request, to post bond). f. Ensure SWPPP complete. incl. Sec. 6.E., 8, and especially Sec. 1, Registration Statement, esp. Construction Activity Operator ; this is to register for a VAR10 permit. g. VAR10 coverage letter (DEQ) is required rip or to receiving Grading Permit. Engineering coordinates, once tree removal plan approved, bond posted, SWPPP complete. h. Submit `tree removal' only VSMP plan. asap. Include Tree Removal in plan title. Later, the tree removal plan will be Amended for proposed 664 W. Rio improvements. From DEQ NPS Nutrient Trading Data Viewer ( site, blue box): <image001.png> Many steps remain. Time is of the essence if project is to have any appreciable time prior to 31-Mar to remove trees. Please call if any questions. Thanks, best, J. Anderson John E.
