REGARDING WATER QUALITY (9VAC25-870-63 & M: THIS DESIGN PROPOSES BY SATISFACTION OF SECTION 44.15.35, THAT WATER QUALITY IS ACCOMPLISHED BY OFFSITE ALTERNATIVES. BASED ON NEW DEVELOPMENT OF BELVEDERE PHASE 3 BLOCK 10, THE WATER QUALITY PORTIONS OF THIS PLAN WILL BE SATISFIED WITH PURCHASING 13.31 IB/YR OF OFFSITE NUTRIENT CREDITS IN THE SAME OF ADJACENT HYDROLOGIC UNIT CODE (02080204). COMPLIANCE OF 9VAC25-870-65.F: OFFSITE ALTERNATIVE IAW 9VAC25-870-69 PURCHASE OF NUTRIENT OFFSET CREDITS IS PROPOSED AND AFFIRMED. JUSTIFICATION FOR OFFSITE CREDITS HAS BEEN PROVIDED UNDER SEPARATE COVER (02/11/2021). STORMWATER QUANTITY COMPLIANCE MVAC25-870-66 PART B SPECIFICALLY DEALS WITH CHANNEL PROTECTION): STORMWATER RUNOFF COLLECTED WITHIN THE BLOCK 10 PROJECT WILL BE CONVEYED THROUGH A MANMADE CONVEYANCE NETWORK TO AN OUTFALL AT THE RIVANNA RIVER. THE NONEROSIVE PASSAGE OF THE 2—YEAR EVENT WILL DISCHARGE AT THE NORMAL RIVER ELEVATION (NRE) OF THE RIVANNA RIVER, AN ADEQUATE CHANNEL AT OR BELOW THE "1% RULE" LIMIT. THIS DETERMINATION IS DOCUMENTED IN A SEPARATE SUBMITTAL TO ALBEMARLE COUNTY (02/11/2021).. THE PROJECT IS IN COMPLIANCE OF CHANNEL PROTECTION, AS MANMADE IMPROVEMENTS (SECTION 1.A) WILL BE UTILIZED ALL THE WAY TO THE NRE OF THE RIVANNA. THIS IS THE POINT OF ANALYSIS OF THE SYSTEM AND THE 1% RULE (SECTION 4.A) REMOVES ANY NEED TO FURTHER DEMONSTRATE CAPACITY OF THE CHANNEL AND NEGATES ANY NEED FOR DETENTION OR ENERGY BALANCE PROVISION.

STEEP SLOPES STEEP SLOPES PRESERVED AND STEEP SLOPES MANAGED PER ALBEMARLE COUNTY CIS DOES EXIST ON THE NORTH EAST SIDE OF THE SITE. THE AREAS WHERE CONSTRUCTION ACTIVITIES OCCUR NEAR PRESERVED STEEP SLOPES, TREE PROTECTION AND SILT FENCE WILL BE INSTALLED AS A PROTECTIVE BARRIER, AS TO NOT DISTURB THE SLOPES. STRUCTURAL PRACTICES 1. SAFETY FENCE (3.01) - A TEMPORARY SAFETY FENCE SHALL BE CONSTRUCTED WHERE DEEMED NECESSARY DURING CONSTRUCTION TO PROTECT THE MANHOLES AND SANITARY LINE FROM CONSTRUCTION TRAFFIC. 2.

The Slate River Nutrient Bank has received operational status through the Chesapeake Bay Watershed Nutrient Exchange Program (Virginia Code § 62.1-44.19:12 et seq.) of the Virginia Department of Environmental Quality. DEQ approved this project and issued a Nonpoint Nutrient Credit Generation Certification: Certificate No. James- 045 and an initial credit release for this project on January 14, 2019. A further credit release was released one year later, on January 2, 2020, upon meeting the success criteria as laid out by DEQ. As of the date of this letter, Ostrya Conservation, Inc. has 79.76 pounds of phosphorus offsets and 266.95 pounds of nitrogen offsets available for transfer in the approved service area in the James River watershed (including the following HUCs: 02080201/Upper James; 02080202/Maury; 02080203/Middle James -Buffalo; 02080204/Rivanna; 02080205/Middle James -Willis; and 02080207/Appomattox). These offsets were certified pursuant to the Chesapeake Bay Watershed Nutrient Exchange Program by the Virginia Department of Environmental Quality and the Virginia Department of Conservation and Recreation to be used as compensation for state or local permit water quality requirements. These offsets have been generated and are transferable according to § 10.1- 603.8:1 of the Code of Virginia. Ostrya Conservation confirms, via this letter, that the Slate River Nutrient Bank is reserving 13.31 phosphorus credits (i.e., 13.31 pounds/year) for use on your Belvedere Phase 3 Block 10 project Reservation of these credits is contingent on putting an "Agreement for Purchase and Sale of Nonpoint Nutrient Offset Credits' in place with Ostrya Conservation, Inc. within three months of the date of this letter.

GENERAL THE PROPOSED DEVELOPMENT OF PARCEL TMP 062A3-00-00-00100, KNOWN AS BELVEDERE PHASE 3 BLOCK 10, PRESENTS A RESIDENTIAL SUBDIVISION UNDER THE NEIGHBORHOOD MODEL DISTRICT PER ZMA-2004-0007. THE PROJECT PROPOSED THE CONSTRUCTION OF 40 TOWNHOME LOTS AND 27 SINGLE FAMILY DETACHED LOTS (PLUS 2 EXISTING SFD LOTS). THIS DESIGN PROPOSES BY SATISFACTION OF SECTION 44.15.35, THAT WATER QUALITY IS ACCOMPLISHED BY OFFSITE ALTERNATIVES. REGARDING WATER QUALITY REQUIREMENT: 9VAC25-870-63 WATER QUALITY DESIGN CRITERIA REQUIREMENTS PER THE ADMINISTRATIVE CODE OF VIRGINIA: "1. NEW DEVELOPMENT, THE TOTAL PHOSPHORUS LOAD OF NEW DEVELOPMENT PROJECTS SHALL NOT EXCEED 0.41 POUNDS PER ACRE PER YEAR, AS CALCULATED PURSUANT TO 9VAC25-870-65." COMPLIANCE: CALCULATIONS SHOWN ON THIS PLAN WERE DETERMINED FROM ACCEPTABLE METHODOLOGY "DEQ VRRM FROM NEW DEVELOPMENT COMPLIANCE SPREADSHEET -VERSION 3.0." THESE PLANS SATISFY THE OFFSITE COMPLIANCE OPTIONS LIST OF § 62.1-44.15:35.D.3 - SECTIONS (i-iv). IT IS OUR UNDERSTANDING THAT THE VSMP AUTHORITY MAY ALLOW THE USE OF OFFSITE COMPLIANCE OPTIONS WHEN, AFTER CONSIDERATION OF ALL PRACTICABLE ONSITE TREATMENT OPTIONS AND THE SPECIFIC ELEMENTS OF THE STATUTE, THE PROPOSED PROJECT IS STILL UNABLE TO COMPLY WITH TREATMENT REQUIREMENTS. BASED ON NEW DEVELOPMENT OF BELVEDERE PHASE 3 BLOCK 10, THE WATER QUALITY PORTIONS OF THIS PLAN WILL BE SATISFIED WITH PURCHASING 13.31 IB/YR OF OFFSITE NUTRIENT CREDITS IN THE SAME OF ADJACENT HYDROLOGIC UNIT CODE (02080204). COMPLIANCE OF 9VAC25-870-65.F: OFFSITE ALTERNATIVE IAW 9VAC25-870-69 PURCHASE OF NUTRIENT OFFSET CREDITS IS PROPOSED AND AFFIRMED.
