Home My WebLink AboutWPO202200042 Review Comments WPO VSMP 2023-03-02John Anderson From: John Anderson Sent: Thursday, March 2, 2023 9:49 AM To: Jim Taggart; David James Cc: Emily Cox; chris.schooley@greenwoodhomes.com; Elizabeth Wassman; Alexander Flint Subject: WPO202200042 - tree removal only: RE: Belvedere Block 10 Timber Hi, Jim, I hope this helps. Item 6.b. is of particular importance; the remainder is relatively straight -forward. For WPO202200042 Belvedere Phase 3 block 10 tree removal only plan approval: [ possible roles for Alexander, Liz —thank you all. j 1. SWM quantity calculations: Pls. provide analysis similar to that provided with RGA Dunlora Village Phase 1 tree removal -only plan, WPO202100063, sheet 5 of plan —Alexander may lend support (image, below). 2. Provide SWPPP using county template similar to SWPPP provided for RGA Dunlom Village Phase 1 tree removal -only plan, approved 2/23/23 —Liz may be able to help with this. 3. Sheet 5 VRRM.xIs lists 26.08 Ac. post-dev land use; sheet 3, Note 15 lists 19.22 Ac. —these values should be identical. 4. Sheet 5: Provide brief narrative that explains mechanism /timing of recordation of forest -open space easement, whether it occurs with a phase 3 block 10 final subdivision plat, for example. Note: If Belvedere Long Holdings, LLC proposes to record FOS Easement with a final subdivision plat (i.e., subdivision not yet recorded), then Albemarle may accept FOS Area (Ac.) as offsetting phosphorus reduction requirement (future blk. 10 subdivision plat), (this tree removal -only plan includes an Exhibit of Areas to be dedicated as FOS Easement, with future final subdivision plat. Also, item 6.b., below. 5. Sheet 3 a. Pls. revise `limits of clearing' label to `limits of tree clearing'. b. Delete label that reads: `Apply mulch, 50' wide ground cover upslope of all tree protection.' c. Provide prominent labels (consistent with WPO202300009 / Biscuit Run tree removal), on the plan: i. Wood chip mulch & temporary seeding shall be installed on all areas within limits of clearing. ii. Tree Clearing only! Mulch all areas within the limits of clearing. d. List Area of limits of clearing, with revised label at item 5.a. above — Acreage to match VRRM.xIs. e. Note 12: Delete word `state'. f Note 2: Replace `recommends' with `requires'. g. New Note: Silt fence is not required as a preliminary perimeter ESC control measure, unless requested by County ESC inspector. h. New Note: Tree protection is required as a preliminary perimeter ESC control - land clearing delineation measure. i. Revise limits of tree clearing to eliminate tree removal across ZMA conservation or ZMA preservation areas, else indicate magisterial or legislative source of permissible tree cutting across ZMA conservation or preservation areas. Ref. sheet 2. j. Revise limits of tree clearing to eliminate tree removal across Albemarle County preserved steep slopes, else indicate magisterial or legislative source of permissible tree cutting across preserved steep slopes; default =impermissible. k. Revisit VRRM.xIs and Note 15 as a final check, once limits of tree clearing revised to eliminate preserved steep slopes, or ZMA preservation or conservation areas. 6. Sheet 1 a. Stormwater Management Compliance Narrative is somewhat confusing: i. Ref. made to 2-phase construction, yet this is phase 3 block 10 plan; pls. clarify whether phase 3 is tree clearing, or a constructive phase of development, with improvements to be reviewed /approved later. ii. Ref in first paragraph to sheet flow appears to be a reference to effect of tree -clearing; please state this explicitly since this is a tree removal only plan. iii. 9VAC25-870-66.D. Requirements: 1. Provide sentence that references analysis provided on sheet 5 of plan (item 1. above). 2. Revise third line to read `... that releases less flow than that of the pre -developed condition ... ' b. Plat at DB 5277 PG 305 is Titled `Plat Showing Vegetative Preservation Easements across TMP's 61- 160, 62-2A1, 62-2C, 62A3-1 & 62-2B.' This is not identical with platted Forest -Open Space Easement and does not include notes specifically required of SWM FOS Easement and does not appear to associate with deed of dedication of SWM easement. Please clarify, or furnish nutrient credits sufficient to meet phosphorus reduction requirements for ? Ac. tree removal. It is unlikely we will be able to quickly apply vegetative preservation easement at DB 5277 PG 315 +, which is accompanied by Declaration of Restrictive Covenants. Trying to derive SWM utility or compliance based on this instrument and plat will take time. Also, it may simply not work. Why, for example, were vegetative easements established, was it for SWM? Clarification may help, but we do not have sufficient information at this point to accept that vegetative easements across these TMPs will be useful, in this instance. c. Erosion and Sediment Control Narrative i. Paragraph 1: Eliminate reference to Silt Fence. ii. Paragraph 2: third line, insert word `surface' between `paved' and 'of'. iii. Paragraph 3: At end of first sentence, add a comma, then `if requested and within 24-hr of request of County ESC Inspector.' SWM Calc., example, WP0202100063 9VAC25-870-66.D, THERE SHALL BE NO NET INCREASE IN RUNOFF VOLUME. BELOW IS TH THIS PHASE, RESULTING FROM THE CLEARING OF TREES. ALL TREE STUMPS SHALL BE 1 =E, AND MULCH UTILIZED AS GROUND COVER FOR ALL AREAS WHERE THE CANOPY THE OVER ALL RUNOFF SHALL EXIT THE SITE AS SHEETFLOW; GRADING OR CHANNELIZATF ZMWATER IS PROHIBITED.

I do understand that there are many items competing for that 01APR slot. I appreciate whatever you can do. 5! The 870-66.1) is the sheet flow quantity matter. The water quality is handled on this version by the 6.9 ac of Forest open space easement already preserved and recorded. We'll obviously add to that with more measures and purchases with the full-buildout VSMP. Thank you. Jim Taggart, P.E.

I hope to glance at this, tomorrow, and then speak with David. Perhaps he and I can team to turn it around quickly —thanks, Jim [ do you need /has blk. 10 acquired /accounted for nutrient credits /w. quality side of things? —assume 9VAC25-870- 66.D. on the quantity side...?

Yes, this is for the 01APR deadline however, it's important to realize that is the deadline to have all the clearing finished. We have several weeks of work to complete after the plan is approved and before the deadline. Is there any way we could expedite this in light of the deadline and the availability of the contractor? We patterned this submittal after the Dunlora plan recently approved, so hopefully we have all the components required for approval. Thank you. Jim Taggart, P.E.

This is his, so I can't say. We should be able to provide an update Friday. I realize this is not immediately helpful, but it is where we are. This is to meet the Apr-1 deadline, right? Again, David should be available to discuss Friday —we'll do our best, thanks for your patience. J.

We submitted a clearing plan for Belvedere BLK10 last week. We have word that we might have a clearing crew available. Could one of you help me discern the status please? Thank you. Jim Taggart, P.E.

What's the status on our VSMP approval? Will this need to be bonded? Thanks.
