CONCLUSIONS This study assessed the impacts of the Major Amendment to the Timberline Church on the short range (2015) street system in the vicinity of the proposed development. As a result of this analysis, the following is concluded: - The development of the Major Amendment of the Timberline Church is feasible from a traffic engineering standpoint. At full development, the Major Amendment will generate approximately 960 weekday daily trip ends, 76 weekday morning peak hour trip ends, and 70 weekday afternoon peak hour trip ends. The Major Amendment will generate approximately 2680 Sunday daily trip ends and 1259 Sunday morning peak hour trip ends. Current operation during the .weekday peak hours at the key intersections is acceptable. With the manual traffic control at the Custer/Illinois and Timberline/South Access intersections, the key intersections operate acceptably during the Sunday peak hour. - In the short range (2015) future, given development of the Major Amendment and an increase in background traffic, the key intersections are expected to operate acceptably during weekday peak hours. During the Sunday peak hour, it is expected that manual traffic control will continue at selected intersections. The operation at the key intersections will be acceptable during the Sunday peak hour with manual traffic control at selected intersections. Increasing the spacing between Sunday services will reduce the overlap of egressing and ingressing vehicles. Pedestrian, acceptable. bicycle, and transit level Of service will be 26 rowhouses that are under construction on the east side of Iowa Drive, south of Custer Drive. When occupied, these residents will add traffic to this segment of Iowa Drive. During the Sunday morning peak hour, it was noticed that people attending .the 11:15am service began arriving as early as 10:45am. This time (10:45am) was the approximate ending time for the 9:45am service. The entrances steadily increased throughout the time that people were leaving the 9:45am service. While the manual traffic control handled this overlap of exiting and entering vehicles, increases in attendance, as are expected with the Minor Amendment and the Major Amendment, will create more vehicle conflicts. It is suggested that the Timberline Church consider increasing the spacing between services in order to lessen the overlap of exiting and entering vehicles. . Pedestrian Level of Service Appendix H shows the pedestrian influence area for the Timberline Church. The site is within areas termed "school walking area" and "transit corridor," which sets the level of service threshold at B for all measured factors, except for visual interest and amenities which is C. There are/will .be four pedestrian destinations within 1320 feet of the Timberline Church. These are: 1) the residential neighborhood to the west; 2) the commercial and residential areas to the north; 3) the residential area to the east; and 4) the residential area to the south (including Fort Collins High School parking lots). Sidewalks currently exist adjacent to and within the site. Sidewalks generally exist adjacent to developed parcels. As development continues to occur, particularly within the Rigden Farm area, sidewalks .will be built to the Fort Collins standards. Appendix H contains a Pedestrian LOS Worksheet. Bicycle Level of Service Appendix H contains a map of the bicycle influence area. There are two bicycle priority destinations: 1) Fort. Collins High School and 2) the Rigden Farm Commercial Center. There are bike lanes on Timberline Road and Custer Drive. Therefore, this site has direct connections to existing bike lanes. Appendix H contains a Bicycle LOS Worksheet. Transit Level of Service Currently, ' Collins Transit a high frequency transit level of this area is not served by Transfort. The Fort System Map (future) shows that Timberline Road will be transit corridor with 20 minute service. The future service will be at B. 25 TABLE 7 2015 Sunday Total Peak Hour Operation Intersection ..

Table 7 shows the 2015 Sunday total peak hour operation at the key intersections (does not reflect manual traffic control). Calculation forms are provided in Appendix G. It is expected that manual traffic control will continue at selected intersections. Later in this TIS, observations and suggestions regarding Sunday peak hour traffic are discussed. Sunday Peak Hour Traffic Control During traffic counting on November 19, 2006, traffic was observed from the upper level of the Timberline Church. The parking lots appeared to be full. Therefore, the attendance was probably normal. At the Timberline/South Access, vehicle queues occurred on all legs depending upon which leg was stopped by the police. Since the through traffic on Timberline Road is not high on a Sunday morning, the police were able to dissipate the queue on the Site Access. Right -turn entrances from northbound Timberline Road could occur, since this lane was "coned -off." The police allowed southbound left -turn entrances to the site to occur while the northbound through traffic was stopped. The control appeared to be handled efficiently at this intersection. The manual traffic control at the Custer/ Illinois intersection created queues on various legs. The police were aware of the signal timing and operation at the Timberline/Custer intersection, such that there were no significant delays to the general public desiring to access the retail center to the north. The queues on various legs were dissipated efficiently. There is currently a "choke point," on church property, just east of the. South Access. A left -turning vehicle at this location could cause delays to entering traffic. The new site plan shows that this "choke point" is eliminated by providing a left -turn lane and two eastbound through lanes. This should provide for much smoother entrances to the parking lots to the east and eventually to the south. A church member suggested that exits via Iowa Drive should be directed (forced) to go straight to Drake Road rather, than turning left on Custer Drive and then going through the Custer/Illinois intersection. This would reduce the number of vehicles going through the Custer/Illinois intersection and, therefore allow it to operate with less delay. If this suggestion were to be implemented, it would fall upon the church and its members to abide by and enforce it. The general public would not be obliged to follow- this.

Figure 6 shows the 2015 weekday background peak hour traffic at the key intersections. It is expected that the Sunday background peak hour traffic would grow similarly to that, which will be experienced on a weekday (plus site generated traffic from the Minor Amendment). Figure 7 shows the 2015 Sunday background peak hour traffic. Trip Assignment/Total Traffic Projections Trip assignment is how the generated and distributed trips are expected to be loaded on the street system. The assigned trips are the kresultant of the trip distribution process. Figure 8 shows the assignment of the new site generated weekday peak hour traffic. Figure 9 shows the assignment. of the new site generated Sunday peak hour traffic. The site generated traffic was added to the weekday and Sunday background peak hour traffic resulting in the forecasted total peak hour traffic. Figures 10 and 11 show the 2015 weekday and Sunday total peak hour traffic at the key intersections, respectively. Signal Warrants As a matter of policy, traffic signals are not installed at any location until such time that signal installation warrants are met according to the Manual on Uniform Traffic Control Devices. It is unlikely that peak hour signal warrants will be met at any of the stop sign controlled intersections. Operation Analysis Operation analyses were performed at the key intersections. The operations analyses were conducted for the short range. future, reflecting a year 2015 condition. It is important to note that the geometry and phasing for the Timberline/Custer intersection was changed for the 2015 short range future. In order to achieve acceptable operation at this intersection, the east leg of Custer Drive was analyzed with an exclusive left -turn lane, a combined left-turn/through lane, and a right -turn lane. This is similar to the Timberline/Drake intersection where dual eastbound left -turn lanes face and a single westbound left -turn lane. The combined westbound left-turn/through lane is also similar to the geometry and phasing at the College/Cherry-Willow intersection in Fort Collins. .It is not likely that the traffic on the west leg of Custer will increase, since this neighborhood is completely built out. Table 4 shows the 2015 weekday background peak hour operation at the key intersections. Calculation forms are provided in Appendix D. The key intersections will operate acceptably. 13 111111101 � 1 "1'r 1011111111' o I -m JL.. 71rv. °� it=Amer, OWONI0001, ;�•• 1 FR' t .� t t{I n uA-t•"�11 If n h 1 FJDPCY l � f.

PROPOSED DEVELOPMENT The Timberline Church is located east of Timberline Road and south of Custer Drive. Figure 5 shows the site ,plan of the Timberline Church. The Major Amendment expansion is shaded. The short range analysis (year 2015) includes development of the Timberline Church and an appropriate increase in background traffic due to normal growth and other known potential developments in the area. Since this is an intermediate level transportation impact study, a long range analysis is not required. Trip Generation - Trip generation is important in considering the impact of a development such as this upon the existing and proposed street system. Table 3 shows the weekday and Sunday trip generation for the Major Amendment using Trip Generation, 7t° Edition as the reference document. The Major Amendment will include 3500 seats. However, some of these seats will replace seats in the existing auditoriums. The net increase in seating is 1750 seats available for a regular Sunday service. Table 3 shows no adjustment with regard to the actual counts versus ITE rates.

The. trip distribution analysis was discussed and agreed to in the scoping meeting. Background Traffic Projections Previously prepared transportation impact studies were used to forecast traffic growth at the key. intersections.( These were the "Timberline Commercial Center TIS," the "Eastbrook Office Park TIS," 11 Intersections adjacent to and near churches, typically experience delay in the time periods between services. The delays are typically of short duration and are generally accepted by church members and nearby residents and businesses. The Sunday traffic counts were compared to that which would be calculated using Trip Generation, 7th Edition, ITE. It was found that the peak hour rates shown in the reference document would overestimate the actual trip generation on this particular day by approximately 10 percent. Pedestrian Facilities There are pedestrian facilities along most streets in this area. Sidewalks exist along Timberline Road, Drake Road, Custer Drive, and Illinois Drive. Sidewalks will be incorporated within and adjacent to this development. Bicycle Facilities Bicycle lanes exist within the cross section of Timberline Road, Drake Road, and Custer Drive. The Fort Collins Bike Map shows Timberline Road, Drake Road, and Custer Drive as "streets with bike lanes." Transit Facilities This area is not served by transit. 10 TABLE 2 Current Sunday Peak Hour Operation Interseon , ;; ° `- ; r Mo�t3ment Level of;;Service;` Sunda Timberline/Custer (signal) EB LT g EB T/RT g EB APPROACH g WB LT C WBT g WB RT g WB APPROACH C NB LT g NB T g NB RT g NB APPROACH g SB LT A SB T/RT g SBAPPROACH g OVERALL g Custer/Illinois' (stop sign) NB LT/T/RT D SB LTIT/RT g EB LT A WB LT A Custer/Iowa (stop sign) NB LT/T/RT g SB LT1T/RT g EB LT A WB LT A Timberline/North Access (RT-in/RT-out) WB RT B Timberline/South Access' (stop sign) WB LT F WB RT g WB APPROACH E SB LT g 1 Does not.reflect manual traffic control 125 t0 Ln N $ 268 Custer �/ 5 - — t r 5 11 N L ro 76 4 North Access co M N r V 46 178 South Access LO It o ul M m = ° �26 T f 1 \ 34 5f 1 i 55 to m i 61 —��- 145� 11 RECENT SUNDAY PEAK HOUR TRAFFIC 8 4— Sunday AM 0 48 /-10 Figure 4 TABLE 1 Current Weekday Peak Hour Operation ... .... ... .

Existing Traffic/Operation Recent traffic counts were obtained in October and November 2006, Figure 2 shows the weekday peak hour traffic at the key intersections. Raw traffic counts are provided in Appendix A. Since the weekday peak hour traffic was obtained over a number of days, the counts were balanced and are shown in Figure 3. Table 1 shows the operation at the key intersections. Calculation forms are provided in Appendix B. All of the key intersections operate acceptably. This area is termed "low density mixed -use residential." In this area, the minimum operation is level of service D at signalized intersections. At unsignalized intersections, the minimum is level of service F (considered to be normal) at arterial/collector or arterial/local intersections and level of service C at collector/local intersections. Appendix B also contains a description of the range of delay associated with each level of service category and the Fort Collins Motor Vehicle Level of Service Standards. Recent traffic counts were also obtained on a Sunday morning in November 2006. The time selected was 10:15-11:45am. This period covered the end of one church service and the. beginning of another service. The services selected were considered to be large services according to Timberline Church representatives. The peak hour within the time period was 10:45-11:45am.. The end of one service occurred at approximately 10:45am. The beginning of the other service occurred at 11:15am. Manual traffic control (Fort Collins Police) was available from 10:40am until 11:15am at the Timberline/South Access to the church and at the Custer/Illinois intersections. Figure 4 shows the Sunday peak hour traffic at the key intersections. Raw traffic counts are provided in Appendix A. Since there was manual traffic control at two intersections, it is not possible to accurately assess the level of service at these intersections. Table 2 shows the operation at the key intersections during the Sunday peak hour. Calculation forms are provided in Appendix C. The calculated level of service is shown at the two manually controlled intersections as though there was no control. This is provided for informational purposes only. It is acknowledged that the westbound left -turning volume at the Timberline/ South Access would not be at the level calculated if there was no manual traffic control. A significant number of these vehicles would have either become right turns to, Timberline Road or would have utilized either Illinois Drive or Iowa Drive to access Custer Drive. 9 SITE LOCATION SCALE: V=1000' Figure 1 3 II. EXISTING CONDITIONS The location of the Timberline Church is shown in Figure 1. It is important that a thorough understanding of the existing conditions be presented. Land Use Land uses in the area are primarily residential or commercial. There are residential uses to the east, west, and south of the site. There are commercial uses north and south of the site. The center of Fort Collins lies to the west of the proposed Timberline Church. Land adjacent to the site -is flat (<2% grade) from a traffic operations perspective. I Roads The primary streets near the Timberline Church site are Timberline Road, Custer Drive, Illinois Drive, and Iowa Drive. The following descriptions are based upon a site visit and the Fort Collins Master Street Plan. Timberline Road is to the west of the Timberline Church site. It is classified as a six -lane arterial according to the Fort Collins Master Street Plan. Currently, Timberline Drive has a four -lane cross section. At the Timberline/Custer intersection, Timberline Drive has northbound and southbound left -turn lanes, two through lanes in each direction, and a northbound right -turn lane. The Timberline/Custer intersection has signal control. The existing speed limit in this area of Timberline Drive is 40 mph. Custer Drive is to the north of the Timberline Church site: It is classified as a two-lane collector according to the Fort Collins Master Street Plan. Currently, .Custer Drive has a two-lane cross section. At the Timberline/Custer intersection, westbound Custer Drive has a left -turn lane, a through lane, and a right -turn lane. Eastbound Custer Drive has all movements combined into a single lane. However, there is enough width for right -turning vehicles to bypass left- turning/through vehicles on the west leg of Custer Drive. At the Custer/Illinois intersection, Custer Drive has. an eastbound and westbound left -turn lane and a through/right-turn lane in each direction. At the Custer/Iowa intersection, Custer Drive has an eastbound and westbound left -.turn lane and a through/right-turn lane in each direction. The Custer/Illinois and Custer/Iowa intersections have stop sign control on Illinois Drive and Iowa Drive. The existing speed limit in this area of Custer Drive is 25 mph. ,Illinois Drive is to the north of the Timberline Church site. It is classified as a local street according to the Fort Collins Master 2 I. INTRODUCTION This intermediate transportation impact study (TIS) addresses the capacity, geometric, and control requirements at and near the proposed Major Amendment to the Timberline Church. The Timberline Church is located east of Timberline Road and south of Custer Drive in Fort Collins, Colorado. The Timberline Church has proposed two expansions. A transportation impact study memorandum (December 4, 2006) was prepared and submitted to the City for the initial expansion (Minor Amendment). During the course of the analysis, numerous contacts were made with the project developer, project engineer, project planner, and the City of Fort Collins staff. This study conforms to the format set forth in the Fort Collins transportation impact study guidelines as contained in the "Larimer County Urban Area Street Standards" (LCUASS). A Base Assumptions Form and related information are provided in Appendix A. The study involved the following steps: - Collect physical, traffic, and development - Perform trip generation, trip distribution, - Determine peak hour traffic volumes; - Conduct capacity and operational level of intersections; - Analyze signal warrants; data; and trip assignment; service analyses on key - Conduct level of service evaluation of pedestrian, bicycle, and transit modes of transportation.

The average setback for exceeds the average 40' setback requested by Natural Resources. Landscaping_ • Appropriate landscaping will be installed in the parking area, around the building, and at the entrances. Circulation: • The two existing Timberline Road access points, and the existing accesses from Illinois Drive and Iowa Drive to the north will continue to be used. A north bound right turn lane is proposed at the southern access on Timberline Road for improved access. Wetlands and Natural Areas: • There are no wetlands or natural areas on the church property. However, the Foothills Channel borders the southeast edge of the site. (iii) Proposed ownership and maintenance of public and private open space areas. • The owner will be responsible for the maintenance of the site. (iv) Estimate of Number of Employees for Commercial and Industrial Uses • Timberline Church currently employs more than 90 people including approximately 50 full-time and 40 part-time personell. The number of employees will grow as the church expands, but it is difficult to determine the ultimate number of employees at buildout. (v) Description of rationale behind assumptions and choices made by the applicant • This project will comply with applicable city standards in an effort to create a satisfactory addition to the city. (vi) Variances • There are no variances being requested at this time. (vii) How Conflicts Between Land Uses are Being Avoided • There are no wetlands or natural areas on the site, and the project exceeds the minimum buffer requirements to the adjacent Foothills Channel. (viii) Neighborhood meeting • Per meeting with Ted Sheppard on 10-30-06, a neighborhood meeting is not required for this project. (ix) Project name and previous project names. • The project name is Timberline Church PUD. Statement of Planning Objectives Page 2 of 2 Timberline Church PUD Property Owners within the Boundaries of Development Timberline Church 2908 Timberline Road Fort Collins, CO 80525 General and Limited Partners and/or Officers Daryl Northrop Benjamin J. Brack Sr. Statement of Planning Objectives (i) Statement of appropriate City Plan Principals and Policies The proposed Timberline Church major amendment is consistent with the City's Comprehensive Plan as per the following: • The church property is located within the LMN zone district. Section 4.5(B)(3)(b)4 lists "Places of worship or assembly with a building footprint exceeding 25,000 SF" as a permitted use subject to review by the Planning Commission. Public improvements include a proposed right -turn lane on Timberline Road as well as some utilities within the property. The church building will be expanded in two phases and associated parking will be added in the south and east portions of the site. Traffic flow patterns within the church property are being modified in order to improve circulation. Bicycle and pedestrian access within the site as well as connectivity to trails and other properties in the area are an integral part of the design. There are no natural areas or hazardous materials on site, but the Foothills Channel borders the southwest edge of the church property. (ii) Open Space, Buffering, Landscaping, Circulation, Transition Areas, Wetlands and Natural Areas Open Space: • A new detention pond will be created in the west portion of the site for water storage and quality. Buffering: • Landscaping will be installed around parking areas to buffer them from adjacent roadways and adjacent properties. The Foothills Channel is buffered from the church parking lot by the proposed detention pond and the setbacks to the channel range Statement of Planning Objectives Page 1 of 2 THE LARSON GROUP � xllOxttt�OtAl 00 RtOtRT iOx C-Soft V/ W �dm w WS i ZI Z� U J�N ° W CL W N m 0: W F- a 5 OF �I ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ m ••• /7I ITraruu � /� t1 T��• l � � �CNIN �y� 1 ' M d� THE LARSON GROUP ca eroe I T:en C- " N �= Z 1.6 0 =a� Q C)ws$ W LLJ J Zo�8 W m§�LL � � W H u 4 OF ^^ ^^W THE a----W LARSON GROUP A IROPIAIIO.AL CORI*, ATIO. nNiw Rom.

Places of Worship in the L-M-N zone with a building footprint which exceeds a total of 25,000 square feet are subject to Planning and Zoning Board review. D. The Major Amendment complies with the applicable General Development Standards with one exception. A condition of approval is recommended with regard to future compliance with Section 3.5.3(C) and (D). E. The Major Amendment grants approval of the future expanded sanctuary for its height, mass, bulk, scale and building envelope only. The recommended condition of approval addresses future compliance with Variation in Massing and Character and Image. F. The Major Amendment does not cause the original P.U.D. to fall out of compliance with regard to neighborhood compatibility. RECOMMENDATION: Staff recommends approval of Timberline Church Expansion Major Amendment, #1-97B, subject to the following condition: Prior to the submittal for building permit for the future expanded sanctuary, the applicant shall provide to the Planning and Zoning Department, architectural elevations in sufficient detail to evaluate compliance with Section 3.5.3(C) and (D) of the Land Use Code. The applicant shall provide architectural plans that mitigate the height, mass, bulk and scale of the new building by such techniques as, but not limited to, creative use of building articulation and forms, strategic placement of light windows, use of horizontal reveals and vertical recesses and projections to create effective shadow lines and using a palette of significantly different building materials to provide a distinct base, middle and top without over -reliance upon any one material such as metal panels or synthetic stucco. Building forms, materials, colors, textures, fenestration and details shall act in concert to ensure that the physical and operational characteristics of the building are compatible when considered within the context of the surrounding area. Timberline Church Expansion Major Amendment - #1-97B June 21, 2007 P & Z Meeting Page 8 between services in order to lessen the overlap of exiting and entering vehicles." Since the T.I.S. was submitted, Timberline Church has implemented two operational changes to reduce congestion on Timberline Road and the inconvenience to non - church related traffic due to manual traffic control. • The interval between the ending and beginning of the two busiest morning services has been increased by 15 minutes. • The easterly parking lot is now required to exit by going north on Illinois Drive and Iowa Drive to Custer Drive instead of a direct route to Timberline Road. Taking Custer Drive west to the signalized intersection with Timberline Road relieves congestion at the Timberline Road/South Access intersection. This allows non -church traffic on Timberline to be less impacted by the manual traffic control. 5. Neighborhood Compatibility: As mentioned, the site is large containing 37 acres. The original P.U.D. anticipated an expanded sanctuary and included four separate buildings devoted to a variety of uses. Under the proposed amendment, the future expanded sanctuary is increased in size but remains approximately within the original building envelope and does not move any closer to the adjacent residential neighborhoods. Further, the four outbuildings are deleted. In terms of net new impact, the issues related to neighborhood compatibility remain approximately the same. Since the Major Amendment is essentially a conversion of uses and not the introduction of new uses, a neighborhood information meeting was not held and there is no new impact on the adjacent residential neighborhoods. 6. Findings of Fact: A. The original P.U.D. was approved under the Land Development Guidance System as a Preliminary in 1997 and a Final in 1999. The original P.U.D. included a future expanded sanctuary of 86,400 square feet containing 2,500 seats as well as four other buildings for child care, assisted living and private school. B. A Major Amendment is processed according to the Land Use Code with applicable standards to be implemented to the maximum extent feasible. Timberline Church Expansion Major Amendment - #1-97B June 21, 2007 P & Z Meeting Page 7 base, middle and top without over -reliance upon any one material such as metal panels or synthetic stucco. Building forms, materials, colors, textures, fenestration and details shall act in concert to ensure that the physical and operational characteristics of the building are compatible when considered within the context of the surrounding area. M. Section 3.6.4 — Transportation Level of Service Requirements A T.I.S. was submitted and is attached. It is important to note that the trip generation (Table 3, page 11) estimates that although the new sanctuary will seat 3,500 persons, some of these seats will replace seats in existing auditoriums. Therefore, the net increase in seating is estimated to be 1,750 for a regular Sunday service. The P.D.P. adequately provides vehicular, bicycle and pedestrian facilities necessary to maintain the adopted transportation Level of Service standards contained in Part II of the City of Fort Collins Multi -Modal Transportation Level of Service Manual in the short term (2015). Note that there is no transit on Timberline Road at this time. The site is presently served by Timberline Road (major arterial), Custer Drive (collector) and Illinois and Iowa Drives (locals). The Timberline/Custer intersection is signalized. All key intersections will continue to operate acceptably, augmented by manual traffic control. Presently, and in the future, Timberline Church will continue to rely on manual traffic control (Fort Collins Police) at two key intersections. According to the Transportation Impact Study, page 26: "With the manual traffic control at the Custer/Illinois and Timberline/South Access intersections, the key intersections operate acceptably during the Sunday peak hour." It is important to note that the T.I.S. states on page 25: "During the Sunday morning peak hour, it was noticed that people attending the 11:15 a.m. service began arriving as early as 10:45 a.m. This time (10:45 a.m.) was the approximate ending time for the 9:45 a.m. service. The entrances steadily increased throughout the time that people were leaving the 9:45 a.m. service. While the manual traffic control handled this overlap of exiting and entering vehicles, increases in attendance, as are expected with the Minor and Major Amendment, will create more vehicle conflicts. It is suggested that the Timberline Church consider increasing the spacing Timberline Church Expansion Major Amendment - #1-97B June 21, 2007 P & Z Meeting Page 6 structure for variation in massing and character and image. This is intentional as the applicant is not prepared at this time to proceed with detailed architectural drawings. Consequently, Staff is prepared to comment on the progress to date and offer a condition of approval requiring final architectural review prior to submittal for a building permit. The amended future sanctuary does not significantly differ from that which is approved. Based on the overall site of 37 acres, the expanded building envelope remains within the basic framework of the buildable area. The primary difference relates to the overall bulk of the proposed amendment. The currently approved plan calls for less square footage with a square -shaped building with four projecting wings featuring courtyards between the wings (see diagram on page 12 of the T.I.S.). In contrast, amended sanctuary calls for the same basic square -shaped building but with all four wings filled in. The result is a larger building with less angularity and more solid contiguous mass. The other difference is in overall height. As mentioned, the currently approved plan calls for a maximum height of 44 feet. In contrast, the proposed amendment calls for a maximum height of 48 feet. Staff finds that the proposed amendment, while more massive and slightly higher, remains in compliance with Section 3.5.1 — Building Project Compatibility and Architectural Character. This is because the context of the new sanctuary located on 37 acres allows for a larger building and because there is no greater intrusion upon the residential neighborhoods than that which is exists under the currently approved plan. Regarding Section 3.5.3(C)(D), a condition of approval is required. Staff recommends the following condition of approval in order to approve the Major Amendment: Prior to the submittal for building permit for the future expanded sanctuary, the applicant shall provide to the Planning and Zoning Department, architectural elevations in sufficient detail to evaluate compliance with Section 3.5.3(C) and (D) of the Land Use Code. The applicant shall provide architectural plans that mitigate the height, mass, bulk and scale of the new building by such techniques as, but not limited to, creative use of building articulation and forms, strategic placement of light windows, use of horizontal reveals and vertical recesses and projections to create effective shadow lines and using a palette of significantly different building materials to provide a distinct Timberline Church Expansion Major Amendment - #1-97B June 21, 2007 P & Z Meeting Page 5 Plan calls for full cut-off luminaries so that there is no illumination trespass over the property line. The house -shield is specified for the fixtures closest to the east and southeast property lines to further buffer the adjacent uses. Section 3.5.1(G) — Building Height Review The increase in height from 44 to 48 feet has been reviewed by a shadow analysis based the angle of the sun at 9:00 a.m. and 3:00 p.m. on December 21 st. The analysis reveals that most of the shadow occurs on the church property. Under the worse case, there is approximately 4,000 square feet of shadowing at 9:00 a.m. on Tract A of Rigden Farm. This site was recently rezoned to N-C and will likely develop as a commercial use. This shadowing will not have a substantial adverse impact on the distribution of natural light on Tract A. J. Section 3.5.3(B)(1) — Relationship of Buildings to Streets, Walkways and Parking — Orientation to a Connecting Walkway With regard to the subject of the Major Amendment, the future sanctuary, there is expected to be multiple entrances whose final locations are not known at this time. There is no public street on the north side of the future building property line upon which to justify an building orientation. The Amendment, however, will retain the existing connecting walkway west to Timberline Road. K. Section 3.5.3(B)(2)(d)2 — Relationship of Buildings to Streets, Walkways and Parking — Orientation to Build -to Lines for Streetfront Buildings This build -to line standard normally requires buildings to be located between 10 and 25 feet of an arterial street. An exception is allowed if the building abuts a four -lane or six -lane arterial street and due to high volume and speed of traffic on this abutting street. A future connecting walkway is expected to be constructed north to Rigden Farm Tract A commercial site and a crosswalk is provided to connect to Illinois Drive. L. Section 3.5.1(B)(C)(E)(F) — Building Project and Compatibility — Architectural Character and Section 3.5.3(C)(D) — Variation in Massing and Character and Image As mentioned, the new sanctuary will be building is 112,222 square feet. This is approximately the size of Sam's Club on Harmony Road and Target on South College Avenue. Since this will be an addition to the north, there will be only three new sides. The Major Amendment provides information on the building envelope, height, mass, bulk and scale only. There is insufficient information by which to evaluate the Timberline Church Expansion Major Amendment - #1-97B June 21, 2007 P & Z Meeting Page 4 mitigating the impact of the expanded parking and features a continuous row of a variety of plant material. C. Section 3.2. 1 (E)(4)(a,b) — Parking Lot Perimeter Landscaping — Trees and Screening As mentioned, the east side of the expanded parking lot that faces the existing and developing attached single family homes is landscaped. Similarly, along the southeast, the expanded parking lot faces the stormwater detention pond and the Foothills Drainage Channel. This perimeter is landscaped as well although not in a continuous row since it does not abut residential. D. Section 3.2.1(E)(5) — Parking Lot Interior Landscaping The parking lot complies with the requirement that no less than 10% of the interior be in the form of landscape islands. E. Section 3.2.2(8 - E) — Access Circulation and Parking Primary access points are already established. The Amendment does not alter the traffic flow. The expanded parking will feature an extension of the existing walkways. There will continue to be five walkways that radiate out from the building core. Bicycle racks are provided near the various entrances. F. Section 3.2.2(J) — Setbacks The existing parking lot along the west side of the buildings will continue to be setback from the right-of-way of Timberline Road by distances that significantly exceed the required 15 feet. G. Section 3.2.2(K)(2) — Parking Lots — Minimum Number of Spaces The church is required to provide a minimum of one parking space per four seats in the assembly area. With the Major Amendment the enlarged sanctuary is expected to serve up to 3,500 parishioners requiring a minimum of 875 spaces. The number of spaces provided is 1,724 thus exceeding the standard. H. Section 3.2.4(D) — Site Lighting — Design Standards The Lighting Plan is designed to provide uniform illumination at levels that are appropriate for the amount of outdoor activity and security. Further, the Lighting Timberline Church Expansion Major Amendment - #1-97B June 21, 2007 P & Z Meeting Page 3 C. Height 1997: 44 feet 2007: 48 feet Net Increase: 4 feet D.

Maior Amendments: The original P.U.D. was approved under the Land Development Guidance System. For projects that were approved under the previous code but whose Major Amendments are now subject to the Land Use Code, Section 2.2.10(B) — Major Amendments - applies: "Major amendments to approved development plans or site specific development plans approved under the laws of the city for the development of land prior to the adoption of this Land Use Code shall be processed as required for the land use or uses proposed for the amendment as set forth in Article 4 (i.e., Type 1 review or Type 2 review) for the zone district in which the land is located, and, to the maximum extent feasible, shall comply with the applicable standards contained in Articles 3 and 4. " 4. Compliance with General Development Standards: A. Section 3.2.1(C)(D) — Landscaping and Tree Protection The Major Amendment leaves existing perimeter street trees intact. Foundation shrubs are provided along the three new sides of the new sanctuary. B. Section 3.2. 1 (E)(1)(a) — Landscaping Standards — Buffering Between Incompatible Uses and Activities The north property line is divided between commercial and attached single family uses. Along the entire east property line is attached single family. The east property line features a buffer yard that ranges in width from 32 to 57 feet. This buffer yard carries a greater burden than the north property line for Timberline Church Expansion Major Amendment - #1-97B June 21, 2007 P & Z Meeting Page 2 EXECUTIVE SUMMARY: Places of worship in the L-M-N zone with a building footprint which exceeds 25,000 square feet are subject to review by the Planning and Zoning Board. The Major Amendment complies with the applicable General Development Standards with one exception. The Major Amendment would grant approval of the future expanded sanctuary with regard to height, mass, bulk, scale and building envelope only. A condition of approval is recommended in order to ensure future compliance for Variation in Massing and Character and Image. COMMENTS: 1.
