SECTION 1 PROJECT NARRATIVE Victorian Properties II, LLC is the owner of tax map parcel 09000-00-00-035DO and James R. Moss is the owner of tax map parcel 09000-00-00-035H0; Victorian Properties II, LLC is the applicant (the "applicant") for a zoning map amendment application known as "1805 Avon Street Extended; which pertains to tax parcels 09000-00-00-035DO and 09000-00-00- 035H0 (collectively, the "property"). The applicant seeks to rezone the 3.627-acre property from R-1 Residential to Planned Residential Development. Currently, each of the parcels has an existing single-family residence and if approved, this rezoning would allow a maximum of 85 units to be developed. TMP 90-35D has an existing full access driveway off of Avon Street Extended, while TMP 90-35H shares driveway access with TMP 90-35A, which has full access onto Avon Street Extended. TMP 90-35H additionallyhas access to private streets Avinity Loop and AvinityDrive which connect to Avon Street Extended. Upon developing the two properties as one cohesive development, the access easements through TMP 90-35A would be abandoned and access to the 1805 Avon Street Extended development as a whole would only be provided from Avon Street Extended. The access easement from the neighboring Avinity Subdivision will be re -purposed for emergency access and will be available for utilization by pedestrians and cyclists as well. The property is adjacent to Church of God Southside, whose use lends itself to be designated as a commercial entrance; Innovative Construction Concepts lies just south of Church of God, and is another commercial entrance in the vicinity of the proposed development. Due to the commercial entrance designations of TMP 90-35B and 90-35C, any proposed entrance on the 1805 Avon Street Extended property would not meet Virginia Department of Transportation (VDOT) spacing standards. As a property with only 126' of frontage on Avon Street Extended, siting an entrance to meet entrance spacing standards is not possible. This report will analyze the spacing between entrances (Section 3), and whether there is a need to install turn tapers or turn lanes (Section 4). The following analyses indicate that substandard entrance spacing is not detrimental to ensuring safe and adequate movements for 1805 Avon Street Ext., Church of God Southside, and Innovative Construction Concepts, as the circumstances of this proposal differ from typical mid- or high -volume commercial entrances that serve daily traffic needs. SHIMP ENGINEERING, P.C. SECTION 2 ENTRANCE SPACING Route 742 Avon Street Extended is a 45-mph collector road With the presence of Church of God Southside on TMP 90-35B and Reynovia Drive immediately across from the church, spacing of an unsignalized intersection and a full access entrance is 335, according to VDOT Appendix F Minimum Spacing Standards for Commercial Entrances (Table 2-2). Similarly, the presence of Innovative Construction Concepts on the other side of Church of God Southside would require 335' between Innovative Construction Concepts' and 1805 Avon Street Ext.s proposed full access entrance. The existing entrance to TMP 90-35D that serves one single-family residence, is 132' from the Church of God Southside's entrance and Reynovia Drive. The entrance is proposed to move approximately 47 towards the northern property line, such that the proposed entrance would be 179' from the Church of God Southside's entrance and 321' from Innovative Construction Concepts' entrance. Due to the narrow shape of the parcel, it is not possible for the entrance to achieve a spacing of 335' as the proposed entrance is positioned as far north as possible on the property. A partial access entrance to the property would only necessitate an exception from spacing standards between the proposed entrance and the entrance to the Southside Church of God, as the minimum spacing standard for partial access entrances is 250' on 45 mph collector roads and therefore spacing requirements between the proposed entrance and Construction Concepts (TMP 90-35C) entrance could be met. We do not propose a partial access entrance with this development because it is critical for future residents of this development to be able to make a left -in to the site when traveling from Charlottesville and a right -out from the development when traveling to Charlottesville; the majority of trips to and from this site will be making these maneuvers. The left -out maneuver could be restricted therefore reducing spacing standards however, since the volume of trips potentially making this maneuver will be minimal, we do not see the benefit in restricting this movement. SHIMP ENGINEERING, P.C. ACCESS MANAGEMENT EXCEPTION REQUEST:TMPs 9035D&9035H 1 4 SECTION 3 TRIP GENERATION: CHURCH OF GOD SOUTHSIDE Entrance spacing between Church of God Southside and the proposed multifamily development does not meet VDOT minimum spacing standards for commercial entrances, however, the nature of trips generated by religious institutions are dissimilar to other commercial uses that would necessitate appropriate entrance spacing. Furthermore, peak hour timeframes differ between that of a church and a multifamily neighborhood. The following trip generation was provided by ITE Trip Generation, loth Edition. A 3,200 square foot church could generate one trip during the weekday morning peak hour and two trips during the weekday evening peak hour. Due to the very low volume of weekday trips of the church and overall low trips generated by the proposed multifamily units, there is no anticipation of conflicts to occur between these two entrances that do not meet minimum entrance spacing. pdap Plot and Equal w.X so�XCE Tnd Den nrna lmn Ea Hery Ctla w.w.avallame. f�y5$JyLm:q¢aw.

The following trip generation was provided by ITE Trip Generation, loth Edition. A 2,300 square foot office could generate four trips during the weekday morning peak hour and five trips during the weekday evening peak hour. Due to the very low volume of weekday trips of the commercial contractor and overall low trips generated by the proposed multifamily units, there is no anticipation of conflicts to occur between these two entrances that do not meet minimum entrance spacing by 14'. wul%E: ` TIP Dlxl Mxlni, IM Ed ..., wuaa.... a,.... 2,JhadN,ldgd..

I ACCESS MANAGEMENT EXCEPTION REQUEST: TMPS 9035D&9035H 6 SECTION 4 TURN LANE WARRANT ANALYSIS Right and left turn lane warrant analyses are provided to indicate low volume of peak hour trips for the proposed multifamily development. Right and left turn lanes are not required, indicating minimal conflicts between new trips and existing background traffic on Avon Street Extended. As the new peak hour trips would not require additional infrastructure for safe and adequate movement on Avon Street Extended, in addition to the existing one to two peak hour trips generated by the church, entrance spacing of 179' would not diminish public access and safety on Avon Street Extended; because turn tapers and turn lanes are not required by the proposed use, minimum entrance spacing would not be needed to minimize conflicts between turn tapers, turn lanes, and the existing commercial entrance of the church. The following 2020 traffic data specific to this portion of Avon Street Extended is provided by EPR, P.C.

ACCESS MANAGEMENT EXCEPTION REQUEST: TMPs 9035D&9035H 1 9 SECTION 5 CONCLUSION 1805 Avon Street is a property designated as "Urban Density Residential" by Albemarle County. Urban Density Residential uses recommend a density of 6-34 dwelling units per acre of all housing types. The proposed rezoning from R-1 Residential to Planned Residential Development for the development of 85 units maximum would bring the density to 24 DUA, aligning with County Comprehensive Plan goals and contributing to overall housing supply in Albemarle. This request for exception from the minimum spacing standards is due to the presence of the Church of God Southside and Innovative Construction Concepts south of the property. However, as a church use, there may be one to two trips occurring during the weekday morning and evening peak hour, with the majority of overall trips occurring on the weekends; as a specialty contractor use, there may be up to five trips during the weekday morning and evening peak hour, with relatively low trip generated overall. Moreover, the proposed 85 maximum multifamily units do not generate high volumes of peak hour traffic, as right and left turn lanes are not warranted with this development. Because turn tapers and turn lanes are not needed with the proposed use, minimum entrance spacing does not have to be established to minimize possible conflicts with new turn lane infrastructure and existing commercial entrances. Due to the low -volume of trips generated by these commercial entrances during typical peak hours of the adjacent residential development, meeting half of the required entrance spacing for Church of God Southside and being 14' short of the required entrance spacing for Innovative Construction Concepts would not impede on daily safe facilitation of traffic in and around 1805 Avon Street Extended.
