The applicant presented the concept plan and staff presented questions to the commission, on the appropriateness of the use and the potential impacts on the district and surrounding properties. The Commission concluded that the use could be appropriate,but that further detail about the layout would ultimately determine its appropriateness, particularly as it relates to adjacent residential properties. Further, the commission agreed that the scale of the improvements could be made to work, if it they were better oriented with Route 20 and the predominant topography. There were two serious unanswered questions: 1) the entrance location and VDOT entrance improvement requirements; and 2)the location of parking lots to adjacent residential properties. The Commission recommended using porous paving or stabilized turf for those parking spaces closest to the adjacent residential parcels. Finally, the Commission agreed with staff that connection to public utilities is reasonable and that the sewer line should be extended using a gravity flow system. CHANGES TO THE PLAN The applicant has submitted a revised plan which includes the following changes (See Attachment E): • They oriented the building better to Route 20; • They differentiated future phases; • They obtained approval from Zoning of their parking study(see Attachment B)which recommends 88 parking spaces. Of these, about half are shown as stabilized sod, located adjacent their residential neighbors; • They show a ped/bike pathway along Route 20; and • They have provided a preliminary water and sewer report,which describes two options for providing public utilities to the site. LEGAL DESCRIPTION Request for special use permit to allow the fraternal headquarters for Kappa Sigma International, in accordance with Sections [13.2.2.2 and 5.1.02] of the Zoning Ordinance which allows for fraternal clubs. The property, described as Tax Map 91 Parcel 16, contains 6.14 acres, and,is zoned R-1 [Residential] and E- C, [Entrance Corridor]. The proposal is located on Scottsville Road(Route 20), approximately one mile south of Mill Creek Drive, in the Scottsville Magisterial District. The Comprehensive Plan designates this property as Urban Density in Neighborhood 4. (See Locator Map as Attachment A) RECOMMENDATION Staff finds that the request for a fraternal club generally complies with the provisions of the Zoning Ordinance and the Comprehensive Plan, and recommends approval of SP 03-91. 1 * * * * * COMPREHENSIVE PLAN AND NEIGHBORHOOD MODEL The subject property is designated Urban Density on the Land Use Plan Map in Neighborhood Four. Following is the recommendation from the Development Area Profiles(page 58),relative to this property: • Upgrade Route 20 and construct bicycle facilities and walkways in conjunction with these upgrades. Determine the right-of-way requirements for these road upgrades and obtain and/or reserve right-of-way as necessary; The Virginia Depaitiuent of Transportation(VDOT)recommends that the applicant dedicate a minimum of 25 feet of additional right-of-way along Route 20. In their first review of the application,they were requiring left and right turn lanes into the site which would require major work in Route 20. The applicant submitted a Turn Lane Warrant Analysis to the Engineering Department and VDOT (See Attachment C). They revised their plan to show a 100 foot taper into the site. VDOT has reviewed the material and agrees that the great majority of Kappa Sigma's traffic will be coming from and going to the north,therefore, a left-turn lane into the site is not necessary,however a right turn lane will be necessary. Therefore, as a condition of approval,the applicant shall satisfy VDOT requirements for an entrance permit. The plan also also shows a ped/bike pathway along Route 20,to be constructed upon demand of the County. Neighborhood Model The following analysis addresses conformity with the twelve principles of the Neighborhood Model: Pedestrian The concept plan includes a ped/bike pathway along the frontage of Route 20. The Orientation design and timing of construction of the pathway should be coordinated with other improvements in the right of way. The plan also shows a sidewalks around the building and a trail around the front lawn. Provision should be made to allow access into the site from the ped/bike pathway along Route 20,potentially from the proposed trail. Neighborhood Not Applicable. Friendly Streets and Paths Interconnections Vehicular and pedestrian connections to adjacent properties should be shown, such that if a signaled intersection is constructed north or south of the site,Kappa Sigma will have access to it in the future,when traffic on Route 20 increases. Parks and Open The plan shows terraced gardens and future picnic pavilions and walking trail. Space Neighborhood This site is within a portion of the Development Areas which has not been developed Centers to it's potential,therefore,the closest neighborhood center may be the City of Charlottesville. 2 Buildings and The Architectural Review Board application will include building elevations and a Spaces of Human detailed landscape plan to ensure consistency with the Entrance Corridor guidelines. Scale Relegated The parking is mostly relegated behind structures and staff believes with ARB Parking guidelines regarding screening of parking areas,this criterion can be met. Mixture of Uses This is a very specific use which does not benefit from a mix of uses. There are residential properties surrounding the site although they will likely not benefit from this use. Mix/Housing Not Applicable. Types Redevelopment Not Applicable. Site Planning With the revised layout,this criterion has been met. that Respects Terrain Clear Boundaries A significant issue for the Rural Areas across the street will be lighting. This site is w/Rural Areas currently surrounded by no commercial lighting of any kind,therefore,whatever lighting is installed has the potential to create a great impact. Therefore, staff proposes conditions below which address this criterion. Entrance Corridor The application has been before the Architectural Review Board for advisory comments regarding their special permit application. The ARB voted 4-0, expressing no objection to the special permit, subject to the following conditions: • Site and building illumination shall be limited to the satisfaction of the ARB. • Landscaping shall be provided to limit the impact of the storm water area on the Entrance Corridor to the satisfaction of the ARB. The ARB made the following suggestion for the conceptual plan, for the benefit of the applicant's preliminary site plan submittal. In addition to all requirements of the ARB Preliminary Site Plan Review Checklist,please provide: • A brick screen and vegetation to eliminate visibility of the dumpster area; 3 • A lighting plan that shows minimal site and building illumination(in terms of both number and intensity). Utilize bollard type lights in place of pole lights whenever possible. Use only full cutoff fixtures; • Eliminate visibility of the 7-space parking lot; • Provide a plant schedule that identifies the proposed trees and shrubs (botanical and common name) and plant caliper and height; • Propose different types of plant materials that share similar characteristics; • Provide large shade trees at the corners of the building and add foundation shrubs; • Show that visibility of mechanical equipment will be eliminated from the Entrance Corridor; • Carefully consider all signage for the site and building; and • Show that illumination of the cupola will be limited and appropriate to the site. STAFF COMMENT The revised concept plan has been reviewed by members of the Site Review Committee,which recommends approval of the special permit. The only remaining issues are: 1)public utilities, 2)vehicular and pedestrian connections on-site, and 3) lighting. Public Utilities The applicant presented an analysis of water and sewer service alternatives,provided as Attachment D. The County policy states that new development within the jurisdictional area for water and sewer should be required to connect. The applicant would prefer to connect to the public water via extension of the water line located on the west side of Route 20 and public sewer by pump station and a 3"force main,which is referred to in their report, on page 4, as "Solution#1". Staff believes the best alternative is what is referred to as "Solution#2",which includes public water service via extension of the existing Albemarle County Service Authority water line and public sewer service via extension of existing ACSA sewer line located along Route 20 and Cow Branch Creek. This provides a public connection,which can serve this site and future development in this part of the Development Area. Staff has been in contact with another property owner interested in utilizing the sewer line and believes a cost-sharing agreement may be possible. Vehicular and Pedestrian Connections Staff asked the applicant to show vehicular and pedestrian connections to the adjoining parcels to the north and south and to the ped/bike pathway along Route 20. The applicant is interested in securing a private entrance and is not interested in sharing access with adjoining parcels. The comprehensive plan calls for pedestrian and vehicular connections in the Development Areas,wherever feasible. However, since the adjacent parcels are not likely to develop in the near future, staff is willing to accept reservations for future vehicular connections and a pedestrian connection to the ped/bike pathway on Route 20. Lighting This site is located in a dark part of the County, therefore any new lighting will have a dramatic effect. Staff believes that the site should be lit with mostly residential-type lighting except within parking lots and along sidewalks where safety maybe a concern. To this end, staff proposes strict restrictions on the use of lighting as described below. 4 RECOMMENDATION WITH CONDITIONS Staff finds that the request for a fraternal club generally complies with the provisions of the Zoning Ordinance and the Comprehensive Plan, and recommends approval of SP-03-91, with the following conditions: 1. The site shall be developed in general accord with the plans, entitled Kappa Sigma Fraternity Headquarters, dated April 2, 2004; 2. Lighting of the site shall be limited as follows: a. Light levels at the property line shall be no greater than 0.001 foot candles; b. No flood lighting of the building is permitted; c. Only the parking lot north of the building shall be allowed pole lights; d. Utilize bollard type lights in place of pole lights whenever possible. Use only full cutoff fixtures; and e. Site and building illumination shall be limited to the satisfaction of the ARB. 3. Final site plans shall show a reservation for future vehicular and pedestrian connections to adjacent parcels to the north and south; 4. Final site plans shall show a pedestrian connection from the ped/bike pathway on Route 20 into the site; 5. A right turn and taper shall be constructed at the entrance in Route 20' to the satisfaction of VDOT; 6. Landscaping shall be provided to limit the impact of the storm water area on the Entrance Corridor to the satisfaction of the ARB; and 7. The Applicant shall construct public water service to the site via extension of the existing Albemarle County Service Authority water line located on the west side of Route 20 and public sewer service via extension of the existing Albemarle County Service Authority sewer line located along Route 20 and the Cow Branch Creek, generally as provided in the report entitled, Preliminary Engineering Report Water and Sewer Facilities for kappa Sigma Headquarters by Draper Aden Associates, dated March 30, 2004. 5 ATTACHMENTS ATTACHMENT A: Locator Maps ATTACHMENT B: Turn Lane Warrant Analysis ATTACHMENT C: Parking Study ATTACHMENT D: Preliminary Engineering Report Water and Sewer Facilities ATTACHMENT E: Concept Plan, entitled Kappa Sigma Fraternity Headquarters, dated April 2, 2004 6 ilit w v < - - 0.0 ...6.011 */ .

The new facility replaces the previous one located on Route 250 West. This letter summarizes our study methodology and recommendations. In preparation for this analysis a parking study was prepared by Draper Aden Associates dated February 26, 2004. The parking study was reviewed by the design team and Kappa Sigma, and then was submitted to the county for review and comment. It is now being used as basis for projected site traffic in this analysis. Traffic Counts Traffic counts along State Route 20 at the project site were performed on Thursday, March 25, 2004, from 7am to 9am (morning) and 4pm to 6pm (evening).

Giride for Lett-Tare Lanes as 7w.-Laoe'llghwayS(6) Based on the traffic counts, the worst-case period to determine whether or not a left-turn lane is warranted is 7:30am — 8:30am. The opposing traffic volume during the peak hour is 169 vehicles and the advancing volume is 627 vehicles (heading to Charlottesville). Based on the above table, the opposing traffic volumes for 100 and 200 vehicles were used to determine the basis for 169 vehicles. Additionally, since State Route 20 has a posted speed limit of 55 mph, the advancing volumes for 50 mph and 60 mph were then used to determine averages as shown below. Opposing Volume Advancing Volume 20% 10% 5% l69 285 378 519 10 ATTACHMENT B Ms.Lori Garrett February 26,2004 Page 3 of 5 Based on the left turn percentages in Exhibit 9-75 and in the above tables, an advancing volume threshold of 627 vehicles corresponds to a left turn percentage of 4%. The left turn percentage of 4% corresponds to 25 left turns as an allowance (627 x 4% = 25 left turns). According to the parking study, a total of 23 vehicles (right turns and left turns) will enter the site during the worst-case peak hour. Based on a 95/5 southbound/northbound directional distribution, 1 vehicle (less than 1% of the advancing volume on Route 20) is expected to turn left into the facility, therefore, a left-turn lane is not warranted. 11 ATTACHMENT B Ms. Lori Garrett February 26,2004 Page4of5 Right Turn Analysis Figure C-1-8 (VDOT Road Design Manual, Volume 1) graphically represents the guidelines for right turn treatment on a two-lane highway. The worst-case peak-hour(4:45pm— 5:45pm) southbound approach volume is 541 vehicles. Based on the 95/5 . southbound/northbound directional distribution, 22 vehicles are expected to turn right into the facility. Based on Figure C-1-8, a right-turn taper is warranted for the Route 20 southbound approach. C-15 - 120 — 100 gitiga:::.:.:ii::.:.....

This letter summarizes our study methodology and recommendations. In preparation for this study, the current site plans prepared by Draper Aden Associates and the Programming Document prepared by Glave and Holmes Associates were reviewed, and the proposed development, as relates to parking needs, was discussed with Lori Garrett (Project Architect with Glave and Holmes), and Mitchell Wilson (Executive Director of Kappa Sigma Fraternity). • Attached Table 1 summarizes the various proposed building facilities based on the programming document. These are reformatted somewhat into a form more appropriate for ultimate conversion into parking needs. It is noted that all development will occur in the initial phase of development, with the exception of the conference facility, boardroom, lodging, and recreation amenities. Table 2 summarizes the various activities to take place on weekdays and weekends, utilizing the planned facilities presented in Table 1. As parking demand is generated by people • (i.e., drivers) rather than actual building facilities, the description set forth in Table 2 is the primary basis for generating parking. That is, because of the unique time, size, and purpose of various activities, normal parking guidelines based on empirical data, building codes, or other sources are not appropriate in this particular case. Although, weekday parking conditions will occur on a more frequent basis, the weekend conditions are critical in this particular analysis because of the anticipated higher level of activity and associated parking need. The key parking generator will be the charter member meetings occurring on weekends, which will involve 30-50 attendees on a somewhat regular basis, and up to 500 attendees every decade or so. 14 'J Blacksburg,Charlottesville,Hampton Roads,Richmond,VA•Raleigh/Durham,NC ATTACHMENT C Ms.Lori Garrett - February 26,2004 Page 2 of 3 generator will be the chapter member meetings occurring on weekends, which will involve 30-50 attendees on a somewhat regular basis, and up to 500 attendees every decade or so. Table 3 provides an estimate of parking demand for each of the different user types — administrative staff, visiting attendees, lodge patrons, etc. — and based on Table 2 assumptions. The big variable in weekday parking demand is whether or not a local meeting (assumed to average 24 attendees) occurs. Without such a meeting, daily parking demand is estimated to be 27, whereas the parking demand including a community meeting increases to 39. The peak parking demand conditions will occur on a weekend. A typical weekend is assumed to include a chapter meeting of up to 50 college student attendees, generating 17 parking spaces (assuming worst case that they all arrive by private auto, with an average of three (3) persons per car). Visitors using the lodging facilities as well as some limited support staff will generate additional parking on weekends. During the summer, Leadership School meetings involving up to 200 attendees will generate a parking demand of approximately 76, again, assuming they all arrive by automobile. Table 4 provides a summary of parking space needs based on the data developed in the first three (3) tables. Estimated parking needs are summarized by weekday and weekend in Table 4. It should be noted that the parking demand data through Table 3 represents the number of vehicles that must be parked during a given time during the day. It is the recommended practice that the theoretical parking demand is increased 15% to determine the actual number of parking spaces to provide. That is, there should be a surplus of 15% to account for vehicles improperly occupying two (2) parking spaces, vehicles in the process of entering or exiting the parking space (but not technically parked), and accounting for spaces which may be vacant in one (1) aisle or area of a parking facility, but not be apparently available to the driver seeking the space in another aisle or area of the parking. With this in mind, it is estimated that the weekly parking space requirement would be 31 spaces, or 45 spaces when a community meeting is taking place. The weekly critical, that is greatest, parking needs occur on the weekend. During a weekend with a chapter meeting event of up to 50 attendees, total parking space requirements are 30 spaces. For the larger chapter meetings occurring, on average, every month or two (2), the total parking space requirement increases to 88 spaces. The once per year or greater events — greater than 300 attendees — generate additional parking demands, which it can be reasonably argued are not be cost effective to construct and maintain parking onsite. That is, the additional parking demand for these larger events should be accommodated at offsite facilities. A generally sound practice for meeting parking demand is to provide sufficient parking to meet those needs that occur on a regular basis, and to meet greater parking needs occurring on an irregular basis by providing offsite facilities, transit, shuttles, and other alternatives for special events. In this case, the key factor to consider is what frequency of parking demand will be accommodated onsite. As previously discussed, weekend events with up to 200 attendees — larger chapter meetings plus Leadership School meetings primarily in the summer — will occur, on average, every month or two (2). Events occurring involving greater parking demand likely will be limited to one (1) or two (2) times per year. Accordingly, it can be argued that providing 15 P-\R03\400\R03456\R03456-05\REPORTS\LTR-04 0226-Garrett-Kappa Sigma HQ Parking-TEF.doc ATTACHMENT C • • Ms.Lori Garrett February 26,2004 Page 3 of 3 a total of 88 parking spaces will accommodate events on all but perhaps several days per year, but not be over-designed in that they will be effectively utilized at least once every month or so. Additionally, the County will allow 120% of the determined parking need, meaning site plans for this project could include between 88 and 106 (88 x 120%)parking spaces. We trust this assessment assists you in the successful development of this important project with a properly sized parking allocation. Sincerely, DRAPER ADEN ASSOCIATES Thomas E.

For larger events, assume additional parking demand accommodated offsite. 2 Lodging—weekend use higher than weekday use (say, 1 space/room versus 0.51 spaces/room), and assume 4 rooms occupied separate from chapter meeting attendees. Assume: 4 spaces. 3 Conference Center, Museum/Library/Archives, Recreational Facilities, Board Room, remaining 4 lodge rooms—assume users of these are included in the Chapter Meeting Room and Lodging parking demand. i9 P•\R0 3\400\R03456\R03456-05\REPORTS\TB L-04 0226-Table 3-TEF.doc ATTACHMENT C Table 4 SUMMARY OF PARKING NEED SCENARIOS Kappa Sigma Fraternity Headquarters A.

This project site is approximately 6-acres of land, located west of and adjacent to State Route 20 and approximately one-half mile south of the signalized intersection of State Route 20 and Route 53. Site visits, discussions with state and local governmental agencies, and preliminary engineering calculations were completed for evaluation of the available options for providing water and sewer utilities for the project. Final approval of the selected utility systems will fall on the two (2) agencies having jurisdiction for these services: Albemarle County Service Authority (ACSA), for the public water and sewer, and the Virginia Department of Health (VDH), Thomas Jefferson District for on-site private utilities. SOIL CONDITIONS Soils were evaluated utilizing the information provided in the Geotechnical Evaluation and Subsurface Exploration for Kappa Sigma that was prepared by Draper Aden Associates (February 4, 2004) and the U.S. Department of Agriculture Soil Conservation Service's Soil Survey of Albemarle County, Virginia, August 1985. The site has an initial layer of organic topsoil approximately six inches in depth. The second layer, of varying depths, consists of ML (silts) and MH (elastic silts). The soil survey classified these soils as "Rabun Clays". The percolation rate provided in the soil survey was estimated to be between 0.6 and 2.0 inches per hour. This type of soil condition is considered moderately well suited for the installation of onsite disposal systems, and additional soil testing would be required as part of the septic field design if onsite treatment is chosen for the project. For this preliminary engineering report, we used an average percolation rate of 1.3 inches per hour for the designated soil type (or 46.15 minutes/inch) as shown in the calculations below. PRIVATE SEWER The Virginia Department of Health has guidelines for estimating sewerage flows, however, none of the classifications directly apply to this type of mixed-use facility. Using the architectural programming document prepared by Glave and Holmes, we have developed the following group occupancies as the worst case scenario for the project: 23 1 j ATTACHMENT D Demand Calculations (from the Health Department Regulations) Office (daily use) - 25 people x 20 gal/person/day = 500 gpd Auditorium- 300 seats x 5 gal/seat/day = 1,500 gpd 8 lodging rooms - 2 people each x 65 gal/per/day = 1,040 gpd TOTAL DEMAND =3,040 gpd Septic Field Calculations (from the Health Department Regulations) log y= 2.00 +0.008(x) where y=SF per 100 gals x =percolation rate (minutes/inch) log y=2.00 +0.008 (46.15 min/in) y= 229.08 Area Required = 229.08 x (3,040gpd/100)= 6,964 square feet Area Required = 7,000 square feet. In addition to the required area, the Health Department requires a reserve area equal to the required area of the field. Therefore, the total area of the site dedicated to a septic field would be 14,000 square feet (or 0.32 acres). PUBLIC SANITARY SEWER ACSA currently has an existing ten (10") inch PVC gravity sewer line located at the south end of the newly constructed Stone Creek Apartments. This sewer line is approximately 2,600 feet north of the site and along State Route 20 near Route 53 (See Figure 1). The manhole at the terminus is approximately 9 feet in depth and would be sufficient to connect a new line to the ACSA system. As an extension of the system, the Service Authority would like to maintain the same pipe sizing; therefore a ten-inch gravity sewer extension is used in this PER for comparison. Two alternative alignments were evaluated in this PER as shown on Figure 1, each following the creek for part of it's length to take advantage of the topography. Another option would be the installation of a grinder type pump station on the site. Sewerage would then be collected in the pump station and pumped via a three-inch force main to the connection at Stone Creek Apartments. for the purposes of this study. PRIVATE WATER SUPPLY On-site water supply systems for this project would involve the development of a well, pressurized tank, and a large ground storage tank with a fire pump and stand-by generator. Based on a minimum fire flow of 500 gallons per minute (gpm) and a minimum duration of two hours, a ground storage tank of approximately 60,000 gallons would be required for fire protection, as was assumed in this study. 24 I ATTACHMENT D PUBLIC WATER DISTRIBUTION SERVICE Located within the same Stone Creek Apartment complex mentioned for sewer service, is an eight-inch (8") ductile iron waterline. The line has an existing valve at the terminus (roughly the same location as the terminus for the sewer line) and would be readily available to connect a new waterline at this location. The average pressure at this point is reported by the ACSA to be 85 pounds per square inch (psi). Based on some preliminary head loss calculations, this pressure would allow for a fire flow of between 1,200 gallons per minute (gpm) and 1,300 gallons per minute (gpm) at the site, with an approximate pressure of 35 pounds per square inch (psi). This seems to be adequate for fire flow without the installation of a fire pump or onsite storage tank, as would be required with a private well. More detailed calculations should be prepared to confirm these initial findings as part of the design of building systems. The Service Authority would like to maintain their 8" waterline in order to accommodate future demands. This line would thus have the capability of providing fire protection and domestic water supply. Two alternate routes were evaluated in this PER (See Figure 1), along State Route 20. Since the ACSA limits only include the areas west of State Route 20, the waterline on the west side of the road seems preferable to ACSA, as well as Kappa Sigma. ENVIRONMENTAL CONSIDERATIONS An additional consideration for the extension of public utilities is the need to obtain environmental permits for impacts to wetlands in and around Cow Branch. Based on our initial assessment, crossings of this creek can be minimized and permitting might be possible without mitigation, however, the wetland limits and permit requirements would need to be determined as part of detailed design. CONCLUSIONS A summary of the options considered in this study, along with estimated construction costs are shown below: WATER SERVICE OPTIONS Alternate 1 Public Water Service via extension of $130,000 Existing ACSA system (west side of SR 20) Alternate 2 Public Water Service via extension of $150,000 Existing ACSA system (east side of SR 20) Alternate 3 On site Service via development of a $195,000 well, fire pump, and tank 2 ATTACHMENT D SEWER SERVICE OPTIONS Alternate 1 Public Sewer Service via extension of $120,000 Existing ACSA system (creek only) Alternate 2 Public Sewer Service via extension of $140,000 Existing ACSA system (SR 20 and creek) Alternate 3 On site Service via development of a $ 55,000 drainfield and tank Alternate 4 Public Sewer Service by pump station $ 75,000 and 3" force main. When evaluating best how to serve this facility, it is important to consider both cost and reliability. Public utilities are typically more reliable and maintenance would not be Kappa Sigma's responsibility, however, public utility bills would arrive monthly. An additional consideration is the comments being received from county staff and the Planning Commission, where they are strongly encouraging the development of public utility systems. Planning Commission has further commented that they would prefer one of the gravity sewer systems presented in this report. With this in mind, Kappa Sigma might choose either of two solutions: Solution #1 — meets Kappa Sigma needs Water Alternate 1 Public Water Service via extension of $130,000 Existing ACSA system (west side of SR 20) Sewer Alternate 4 Public Sewer Service by pump station $75,000 and 3" force main. TOTAL BUDGET = $205,000 Solution#2—address both Kappa Sigma and county needs Water Alternate 1 Public Water Service via extension of $130.000 Existing ACSA system (west side of SR 20) Sewer Alternate 2 Public Sewer Service via extension of $140,000 Existing ACSA system (SR 20 and creek) TOTAL BUDGET = $270,000 Hopefully, cost sharing of $65,000 can be developed to better meet county needs with solution #2. We look forward to receiving direction from Kappa Sigma and moving into detailed design services as soon as possible. 26
