Howes Suite 106 Fort Collins, CO 80521 OWNER: Kingston Associates 1125 W. Drake Fort Collins, CO 80526 PROJECT DESCRIPTION: A request for a Preliminary PUD for 52 single family lots on 16.09 acres, located approximately 1/4 mile west of South Shields Street and north of Horsetooth Road at Seneca Street. The site is zoned R-P, Planned Residential. RECOMMENDATION: Approval with conditions EXECUTIVE SUMMARY: The applicant proposes 52 single family lots on this 16.09 acre site. The proposed density is 3.23 dwelling units per acre. Lots range in size from 6,000 to 19,904 square feet with an average lot size of 8,413 square feet. All of the lots gain access from local streets within the development. The project has three entry points, the main entry being from Horsetooth Road at Seneca with secondary access from Seneca to the north and Patterson to the east. This proposal is compatible with existing surrounding development and meets the criteria of the Residential Density Chart and the All Development Point Chart of the Land Development Guidance System. Staff is recommending conditional approval based on concerns of street tree locations along Seneca Street and Horsetooth Road and concerning the location of the entrance pillar features.

Please accept this correspondence as an overview of our Kingston Woods, PUD to be developed and built in southwest Fort Collins. Kingston Woods is located upon a 1-6 acre farmstead owned by the Werner family. Our neighborhood design centers upon an extremely valuable natural feature of the land; a grove of oak and spruce trees. The trees are reputed to be more than eighty years old and are a striking feature of the west Horsetooth Road landscape. The project is located in a convenient "in -fill" location, close to existing schools and shopping facilities. The Pleasant Valley Canal is located on the western boundary of the property. Mature stands of trees along the ditch provide a pleasant buffer and source of shade from the late afternoon sunshine. We will offer a wide variety of single family floor plans in affordable price ranges. As is the case in all of our developments, we will strictly enforce conformance with covenants and architectural standards. The southern perimeter of the project (Horsetooth Road frontage) offers both a challenge and an opportunity. Growing traffic counts along the Horsetooth Road arterial corridor will result in levels of traffic -generated noise. Given that concern, our development plan proposes a landscaped greenbelt along the Horsetooth frontage, (30 to 50 feet in width) as well as average lot depths of approximately 110 feet for those lots that "back in" to the arterial. The frontage also presents a very attractive opportunity to design and build an effective entry element to the neighborhood. The Pleasant Valley Canal parallels Horsetooth Road along the southwest perimeter of the parcel. 2 In addition, the mature stand of trees surrounding the farmhouse provide a unique opportunity for a dramatic entry to the future neighborhood. We have located Seneca Drive immediately to the west of those trees in order to max;m;ze the "welcome to our neighborhood" feeling that future Kingston Woods families will experience upon entering the new community. We look forward to working with planning and engineering staff members in designing a streetscape along Horsetooth Road that conserves as much of the existing vegetation as possible. All open space in Kingston Woods will be owned and maintained by the Kingston Woods Homeowner's Association. (Greenbelt and detention areas included, as well as much of the Pleasant Valley easement, as allowed by the ditch company). Single family densities will be 3.25 units per acre (52 units on 16.049 acres/gross ) Kingston Woods is designed and will be developed to be a truly unique single family development in southwest Fort Collins. The mature trees are indeed striking and will be enjoyed as a quality of life feature by the future families of Kingston Woods. Thank you for your consideration. I look forward to working with you during the development review process. Sinc ely, "`"'ate/ William L. Neal Kingston Woods Associates The Ashland -a two store, plan Iron!

This traffic study assessed the impacts of Kingston Woods PUD on the short range and long range street system in the vicinity of the proposed development. The following summarizes the significant findings as a result of this study: - Traffic from the Kingston Woods PUD and the adjacent residential development can be handled on.the area streets with various improvements. - Traffic operation at the area intersections is acceptable. L - The Kingston Woods PUD will gain primary access to the street system via Seneca Street, which will intersect with Horsetooth Road at a T intersection. - At the short range future, the key intersections operate acceptably. At the Horsetooth/Seneca intersection, the southbound left turns will experience delays which are common at arterial/ local street intersections with stop sign control. The following auxiliary lanes should be built at the Horsetooth/Seneca intersection: 1) westbound right -turn lane, 2) eastbound left -turn lane, 3) southbound right -turn lane, and 4) southbound left -turn lane. These can be striped on anticipated new pavement. Additional widening will not be necessary. - At the long range future, the key intersections will operate acceptably, except for the southbound left turns at the Horsetooth/Seneca intersection, which will experience some delays. It is expected that both Horsetooth Road and Shields Street will be built to four lane cross sections. Right -turn lanes are recommended on the south, east, and west approaches of the Horsetooth/Shields intersection. A full width right-turn-auxi:i-iary-- lane is not required on Horsetooth Road approaching Seneca Street. A 40 foot radius or taper only will provide a safe, efficient exit for right -turning traffic from Horsetooth Road. - Seneca Street to the south of Horsetooth Road should either be moved to increase the distance from Seneca Street to the north or line up with Seneca Street to the north. If these options are not possible, then the center lane on Horsetooth Road should be striped as a two-way left -turn lane. .i � i i Kingston Woods PUD - Preliminary, #58-91 January 27, 1992 P & Z Meeting Page 2 COMMENTS: 1. Background• The.surrounding zoning and land uses are as follows: N: R-P; multi -family residential (Casa Grande PUD) and R-L-P, single family residential (Wagonwheel PUD) S': r-1-p; single family residence and vacant, (proposed church site and single family residential as shown on the Seneca Master Plan) and R-E; single family residential (Skyline Acres) E: R-P; vacant (proposed single family residential- The Residences at Horsetooth Commons) and proposed multi- family residential (Tract C of. Horsetooth Commons Master Plan) W: R-P; rural single family residence, Horsetooth Stables, and Pleasant Valley and Lake Canal There is currently a single family residence with scattered out buildings located at the south end of the property. The remainder of the property is undeveloped. The property was annexed into the City of Fort Collins in April of 1980 as part of the Werner Annexation and zoned R-P, Planned Residential. In May of 1981 a proposal, known as Kingstowne PUD-Final, #117-80A, was given final approval by the Planning and Zoning Board for 123 condominiums on 16 acres. The Kingstowne PUD has since expired. 2. Land Use: The proposed density of 3.23 dwelling units per acre is supported by a score of 70% on the Residential Density Chart of the L.D.G.S. Points were awarded for proximity to a neighborhood park___ (Rossborough Park), a major employment center (Rocky Mountain High School), a transit stop (along Horsetooth Road), and for contiguity to existing urban development. No neighborhood meeting was held. Staff finds that the proposed use is compatible with the surrounding proposed and existing uses. 3. Design: The entry design feature for this proposal highlights the prominent mature stands of trees found on this 16 acre farmstead. The applicant proposes to retain the majority of existing mature trees on site. The applicant is proposing a low entrance wall feature with double pillars on either side of the sidewalk to create a stately entrance to the property at the main entrance on Horsetooth Road. The stone pillars encroach in the right-of-way I. Introduction 1 Kingston Associates is proposing to build a single family detached residential development, located north of Horsetooth Road and on both sides of Seneca Street (extended) in Fort Collins, Colorado. The site location is shown in Figure 1. This development is known as Kingston Woods PUD. The parcel of land is located south of the Wagonwheel 2nd Subdivision and west of the Horsetooth Commons PUD. The Wagonwheel 2nd Subdivision is almost fully built out. Seneca Street currently stubs at its south property line. Kingston Woods will be responsible to extend Seneca Street to Horsetooth Road. Horsetooth Commons PUD has only a few commercial uses built. Richmond Drive has been built through Horsetooth Commons, intersecting with both Shields Street and Horsetooth Road. The "Casa Grande PUD Traffic Impact Study," May 1985, the "Williamsburg PUD Site Access Study," September 1986, and all their respective addendums were used as references for this traffic study. Horsetooth Road is classified as an arterial on the Fort Collins Master Street Plan. The segment between Shields Street and Taft Hill Road is currently two lanes with a rural cross section, with widening at the Shields Street and the Taft Hill Road intersections. There is signal control at the Horsetooth/Shields and Horsetooth/Taft Hill intersections. All other intersections are stop sign controlled with Horsetooth Road receiving the right- of-way. It is posted at 35 mph. In the future, Horsetooth Road is expected to have a four lane cross section with turn lanes at appropriate locations. Shields Street is classified as an arterial on the Fort Collins Master Street Plan. It is a street of varying width south of Horsetooth Road. North of Horsetooth Road, Shields Street has a four lane urban cross section with auxiliary turn lanes and a raised median at some locations. It As proposed to have a four lane urban cross section with turn lanes at appropriate locations in the future. It is posted at 35 mph in this area. There are signals at the Shields/Harmony intersection to the south of Horsetooth Road and at the Shields/Casa Grande, Shields/Swallow, and Shields/Drake intersections to the north of Horsetooth Road. Seneca Street is a local street north of Horsetooth Road. It is not built from the south property line of Wagonwheel to Horsetooth Road. The Fort Collins Master Street Plan indicates that Seneca Street is a collector street south of Horsetooth Road. However, this portion immediately to the south of Horsetooth Road has not been built. At the present time, plans indicate that Seneca Street south of Horsetooth Road will be 375 feet west of Seneca Street north of Horsetooth Road. Land uses in this area are residential, commercial, and open space. Residential uses are north and southeast of the proposed 1 Kingston Woods PUD. Woods. The future east of this site. Kingston Woods PUD. There is open space south and west of Kingston Horsetooth Commons commercial development is The center of Fort Collins lies northeast of II. Existing Conditions The most recent daily traffic counts were obtained in 1991. These counts are one way volumes on Shields Street and Horsetooth Road, and are shown in Figure 2. Peak hour intersection counts ' were obtained in February 1991 at the Horsetooth/Shields intersection and in November 1991 at the Horsetooth/Richmond intersection. These counts are also shown in Figure 2. Raw data is shown in Appendix A. ' With the existing control at the two counted intersections, the peak hour operation is shown in Table 1. The operation at the signalized intersection is deemed to be acceptable. Acceptable operation is defined as level of service D or better. Descriptions of level of service from the 1985 Highway Capacity Manual for ' signalized and unsignalized intersections are provided in Appendix B. Calculation forms for the operation shown in Table 1 are provided in Appendix C. At the stop sign controlled Horsetooth/ Richmond intersection, minor street left turns are at levels of service C and D. This level of operation is due to the traffic flow on Horsetooth Road during the peak hours. Based upon historical traffic data on Horsetooth Road, level of service D operation probably occurs for 3-4 hours a day including the peak hours. III. Proposed Development Kingston Associates is proposing to develop 52 single family lots on a parcel of land north of Horsetooth Road and on both —s-i-des of Seneca Street (extended). A proposed site plan is shown in Figure 3. Two future years were selected for analysis. The short range future was 1993 and the long range future was 2010. A. Trip Generation Trip generation estimates for Kingston Woods PUD were obtained from Trip Generation, 4th Edition, ITE. Table 2 shows trip generation on a daily and peak hour basis.

Background Traffic Background traffic is defined as the traffic that is and/or will be on the area streets that is not related to the proposed development. The intersections considered for the operations analysis are Horsetooth/Shields and Horsetooth/Seneca. Background traffic for impacted streets was projected for each of the future years analyzed (1993 and 2010). Background traffic was projected to increase at 2 percent per year for short range future years. This rate of increase is normal for streets and roads in the City of Fort Collins. It accounts for general traffic growth and some level of continued development in the vicinity that would also contribute to traffic growth. Long range traffic projections were obtained from the North Front Range_Regional Transportation Plan, 1990. This document contains year 2010 daily traffic projections on the streets in this area. These projections assume development of Kingston Woods PUD as well as other parcels in this area of Fort Collins. The daily traffic volumes were factored to obtain peak hour directional volumes using historic peak hour to daily traffic ratios. Turning movements at the Horsetooth/Shields intersection were then synthesized using existing turning volumes and future land use projections. C. Trip Distribution Trip distribution was determined based upon an evaluation of attractions for home -based productions and the most likely routes available to travel to those attractions. The directional distribution of the approaching and departing traffic generated at the proposed uses is a function of: - Geographic location within the City of Fort Collins - Location of employment and business centers which are likely to attract trips from this area - Access to the site. Figure 4 illustrates the trip distribution percentages used -in the subsequent traffic assignments. D. Traffic Assignment and Intersection Operation Using the vehicular trip generation estimates presented in Table 2 and the trip distribution assumptions, the site generated traffic was assigned to the area street network. The initial network consisted of Horsetooth Road and Shields Street as they are today. Seneca Street was added to the network from the existing stub in the Wagonwheel Subdivision to Horsetooth Road. The analyzed intersections were Horsetooth/Shields with the existing signalization and Horsetooth/Seneca with stop sign control. The Horsetooth/Seneca intersection location is shown in Figure 3. The traffic assignment shows some vehicle trips from the Wagonwheel 3 [1 11 11 11 11 I I TRIP DISTRIBUTION Figure 4 Subdivision to eastbound and westbound Horsetooth Road,. utilizing Seneca Street and passing through the Kingston Woods PUD. This route will offer a convenient time and distance savings for some present and future residents of Wagonwheel subdivision. However, most Wagonwheel subdivision residents will find it shorter and more ' convenient to utilize Shields Street via Casa Grande as their primary access route. These judgments are reflected in the traffic assignments. ' Figure 5 shows the short range (1993) peak hour traffic assignment. This assignment also includes a 2 percent per year increase in background traffic as described earlier in this report. Table 3 shows the peak hour operation at the key intersections. Calculation forms are provided in Appendix D. The signalized Horsetooth/Shields intersection will operate acceptably with the I existing geometrics. At the Horsetooth/Seneca intersection, left - turn entrances will operate at level of service A. With a combined right -and left -turn lane on southbound Seneca Street, the operation will be at level of service E. This is due to the higher number of left -turning vehicles which will delay the right -turning vehicles. With separate lanes,.the right turns operate at level of service A and the left turns operate at level of service E. ' Based upon recent research, the delay per approach vehicle will be 21-31 seconds during the morning peak hour and 13-23 seconds during the afternoon peak hour. Using delay criteria from the 1985 Highway Capacity Manual, the operation of these left turns would be in the level of service C/D category even though the operations technique shows the level of service in category E. It is recommended that this operation be accepted. At the new Horsetooth/Seneca intersection, the following geometry is recommended: 1) westbound - one through lane and one right -turn deceleration lane (310 feet including taper for stop condition and 240 feet including taper for a 15 mph turn); 2) eastbound - one through lane and one left -turn deceleration/storage lane (310 feet including taper plus 25 feet of storage); 3) southbound - one left- _.' _turn.lane (100 feet) and one right -turn lane; and 4) northbound - one lane. A westbound acceleration lane can be striped on the widened segment of Horsetooth Road if that is the City's desire. The widened area will extend to the west property line (5901+ from Seneca). At 35 mph, the acceleration lane including taper should be 420 feet. This can be striped on the widened segment of Horsetooth Road. This geometry can be accomplished with widening only on the north side of Horsetooth along the frontage of the Kingston Woods PUD property. There are plans to extend Seneca Street to the south of Horsetooth Road. However, Seneca Street to the south is 375 feet (on centers) west of the proposed Seneca Street to the north. When Seneca Street to the south is built, it is likely that the south side of Horsetooth Road will be widened. The left -turn lanes between the two Seneca Streets will have adequate storage lengths in each direction, but will not have the full deceleration lengths 1 4 Q W Z W h M st Lo T h 4 / 13 —J 659/438 —t 19/68 231/661 HORSETOOTH N G J W_ 2 h h N 00 Lo O co T \ \ to co �t 105/60 480/292 98/110 1 1 SHORT RANGE PEAK HOUR TRAFFIC Q N 137/355 135/495 79/110 )11 00 co mmoo \OD coho CD It AM/PM Figure 5 ' Table 3 Short Range Peak Hour Operation 1 Level of Service (Delay or Reserve Capacity) ' Intersection AM PM Horsetooth/Shields (signal) C (23.1 S/V) C (24.4 S/V) ' Horsetooth/Seneca (stop sign) SB LT/RT (one lane) SB LT SB RT EB LT E (36) E (36) A (715) A (828) E (97) E (90) A (410) A (464) Table 4 Long Range Peak Hour Operation ' Level of Service (Delay or Reserve Capacity) Intersection AM P11 Horsetooth/Shields (signal) D (25.4 S/V) C (23.7 S/V) Horsetooth/Seneca (stop sign) -' - - SB LT SB RT EB LT 1 1 1 F (-30) E (19) A (813) A (546) A (647) C (261) Kingston Woods PUD - Preliminary, #58-91 January 27, 1992 P & Z Meeting Page 3 and would require a revokable encroachment permit from the City. Staff is recommending, as a condition of approval, that the pillar issue be resolved prior to final approval. The greenbelt area along Horsetooth Road will be landscaped with a variety of conifer and deciduous trees to provide a buffer for the lots backing onto Horsetooth Road. The lot depths are less than what is required by strict application of the zoning code for lots backing onto an arterial. If the greenbelt area is included, the actual distance from the front lot line to the Horsetooth Road right-of-way will be greater than 150' for all lots except lot 5 of Block 3. The greenbelt area behind this lot will be given more attention with groupings of evergreen trees and Burr Oaks. The applicant has indicated that street trees will be provided along both Horsetooth Road and Seneca Street. The preliminary landscape plan does not indicate the location or species of these trees. Staff is recommending, as a condition of final approval, that a final landscape plan be submitted showing the location and type of street trees being proposed for Horsetooth Road and Seneca Street. Additional information on the grass mix for the greenbelt areas along Horsetooth and for the detention pond should be included in the final landscape plan, as well as all standard requirements for a final landscape plan. The eastern most lots, south of Patterson Drive, are adjacent to a master planned multi -family area (Tract C of Horsetooth Commons Master Plan). The applicant will -be required to provide an appropriate buffer between these land uses. The applicant has indicated that he will provide a 6' wood fence at the time of building construction. Fencing details will be included with the final submittal. A 20' access and utility easement is located along the eastern side of the Pleasant Valley and Lake Canal. A pedestrian/bike trail has been Master Planned in this area according to the Parks and Recreation Department. This future trail easement will be clearly designated on the plat and site and landscape plans to provide advance notice to all future home buyers that a City trail will someday run along the backs of those lots. Typical setbacks are 5' side, 15' rear, 20' front, and 20' corner side setbacks. in each direction. Ideally, the two Seneca Streets should have more separation or meet at a four leg intersection. If either of these options are not possible, then the center lane on Horsetooth Road between the two Seneca Streets should be striped as a two-way left -turn lane. Figure 6 shows the long range (2010) peak hour traffic assignment which includes the background traffic on the area streets. Table 4 shows the peak hour operation at the key intersections. Calculation forms are provided in Appendix E. By this future time, it is expected that Horsetooth Road and Shields Street will have four lane cross sections as per Fort Collins arterial street standards. At the Horsetooth/Shields intersection with a four lane cross section with no exclusive right -turn lanes, the overall intersection operation will be at level of service F and E, in the respective peak hours. With exclusive right -turn lanes on every approach except the north approach, the operation improves to levels of service D and C, in the respective peak hours. At the Horsetooth/Seneca intersection, operation of the left -turn exits will be at level of service F and E in the peak hours using the 1985 Highway Capacity Manual analysis technique. However, the range of delay per approach vehicle will be 32-42 seconds in the morning peak hour and 23-33 seconds in the afternoon peak hour. These delays are considered to be at level of service D/E and D, respectively. There is little that can be done to improve this operation. With good signal progression on Horsetooth Road, this operation could be improved by one level of service category. This level of service occurs at many arterial/local street intersections throughout Fort Collins. This type of operation is generally accepted. . With the four lane cross section on Horsetooth Road, a right - turn deceleration lane is no longer warranted. It is recommended ' that a radius allowing a 15 mph turn (401) or a simple taper (approximately 90 feet long) be designed for this access. Either of these options will reduce the speed differential in the right travel lane and _provide a safe, efficient exit for_ri_ght_turning traffic. This treatment will reduce the likelihood of rear -end accidents at this location. ' IV. Conclusions I , The following summarizes the significant findings as a result of this study: - Traffic from the Kingston Woods PUD and the adjacent residential development can be handled on the area streets with various improvements. ' - Traffic operation at the area intersections is acceptable. 11 5 11 5/ 15 1010/700 —i 20/70 360/1030 HORSETOOTH Q N N 0 J W_ 2 00 N u> Ln a N00 in o rn cTc a �— 170/400 I UO('120/175 215/790 i 0 170/95 765/465 160/180 0 o to co C`M .t T 00 T 000 T T T M T AM/PM LONG RANGE PEAK HOUR TRAFFIC Figure 6 ' - The Kingston Woods PUD will gain primary access to the street system via Seneca Street, which will intersect with ' Horsetooth Road at a T intersection. - At the short range future, the key intersections operate acceptably. At the Horsetooth/Seneca intersection, the southbound left turns will experience delays which are common at arterial/ local street intersections with stop sign control. The following auxiliary lanes should be built at the Horsetooth/Seneca ' intersection: 1) westbound right -turn lane, 2) eastbound left -turn lane, 3) southbound right -turn lane, and 4) southbound left -turn lane. These can be striped on anticipated new pavement. Additional widening will not be necessary. - At the long range future, the key intersections will ' operate acceptably, except for the southbound l.eft turns at the Horsetooth/Seneca intersection, which will experience some delays. It is expected that both Horsetooth Road and Shields Street will be built to four lane cross sections. Right -turn lanes are ' recommended on the south, east, and west approaches of the Horsetooth/Shields intersection. A full width right -turn auxiliary lane is not required on Horsetooth Road approaching Seneca Street. ' A 40 foot radius or taper only will provide a safe, efficient exit for right -turning traffic from Horsetooth Road. ' - Seneca Street to the south of Horsetooth Road should either be moved to increase the distance from Seneca Street to the north or line up with Seneca Street to the north. If these options are not possible, then the center lane on Horsetooth Road should be striped as a two' -way left -turn lane. II n 1 6 Preliminary Drainage Report for KINGSTON WOODS P.U.D. Ft. Collins, Co. Dec. 2,1991 GENERAL Kingston Woods P.U.D. is a proposed single family development located in the SE 1/4 of Section 27, Township 7 North, Range 69 West of the 6TH P.M., in Ft. Collins, County of Larimer, State of Colorado. Methods outlined in the City of Fort Collins' Storm Drainage Design Criteria and Construction Standards were used in the calculations for the stormwater runoff portion of this study. Additional references were made to the Urban Drainage Criteria Manual as needed. Summary calculations and other supporting material is contained in an appendix to this report. SITE DESCRIPTION The site currently is open pasture land containing approximately 19 acres with a few existing farm buildings located in the southern portion. The overall flow pattern is from southwest to the northeast corner at an approximate slope of 1.2 percent. The southeast portion of the site currently sheet flows toward and across the east boundary into what is currntly titled Horsetooth Commons P.U.D.. Existing flow on Horsetooth Road is to the east at approximately 1.1 percent. The site is bounded on the northwest by Wagonwheel Filing No. 2, to the northeast by Casa Grande P.U.D., to the east by Horsetooth Commons P.U.D., and to the west by Horsetooth Stables. The Pleasant Valley and Lake Canal irrigation canal runs the full length of the west boundary while Horsetooth Rd. borders the south boundary. ' PROPOSED IMPROVEMENTS The proposed development will consist of 52 single family residential lots of no less than 6000 SF each. Existing Seneca Street, which ends on the north boundary of the site, will be extended south through the site to intersect with Horsetooth Rd. Two east -west residential drives, Patterson and Sanford, will accomodate interior traffic across Seneca St. with cul-de-sacs located at the west end of these streets. Patterson Dr, will dead-end on the east boundary of the site to accomodate a proposed drive in Horsetooth Commons P.U.D. I 7 L Runoff flows for a majority of the site will be routed to a detention pond in the northeast corner of the property. A proposed storm sewer was included in Chaparral P.U.D. to accomodate the 2yr. historic runoff from this site. Runoff values calculated in this report are consistent with the Chaparral P.U.D. calculations at this point. Overlot grading will rerout the majority of flow from the southeast portion of the site to the detention pond, in effect reducing developed flow across the east boundary to a value less than existing undeveloped. Developed flows running north on Seneca St. will be consistent with calculated flows in Wagon Wheel Subdivision to the north. Approximately 300 LF of the Pleasant Valley and Lake Canal irrigation ditch currently runs along the north shoulder of Horsetooth Road from the southwest corner of the site where it turns southeast through an existing bridge culvert crossing under the road. Because of the required widening and repaving of Horsetooth Road in conjunction with this development, the existing box culvert will be extended and the existing canal will be relocated approximately 10' to 15' north. A cross-section view of the canal relocation is shown on the Drainage & Grading map accompanying this report. January 30, 1992 A.L.Grant, Jr., President Casa Grande Condominium Association 3518 Laredo Lane Fort Collins, CO 80526 Dear Mr. Grant, Thank you for your recent letter and comments concerning the proposed Kingston Woods PUD. The Planning and Zoning Board received the letters from the Casa Grande neighborhood on Friday prior to their regular monthly meeting n Monday, January 27th. Your comments were glv" consideerr by the Board when the proposed Kingston Woods PUD was given preliminary approval as part of the consent agenda at that meeting. Planning Staff has since contacted the owners and developers of Kingston Woods PUD to see if they will meet with the Casa Grande neighborhood to discuss alternative solutions. Planning Staff has recommended that the developer provide additional trees and shrubbery along the north property line to create more of a visual barrier along that property line. The developers indicated that they would gladly meet with the Casa Grande neighborhood.—'Q�— ,� that it is very likely that home buyers will fence their rear lot lines. Can be. Issues such as fencing and landscaping are typicaliyissues that-aro -resolved prior to final approval. Planning Staff will continue to work on these issues and will help coordinate a meeting between the developers and the neighborhood to resolve the,Cissues prior to the final hearing, tentatively scheduled for April 27, 1992. Thank you for your interest in this project. I encourQge you to contact the Planning Department at 221-6750 or stop in at the office at 281 North College'if you have additional questions and concerns or if you would like to look at the proposed plans for Kingston Woods PUD. Sincerely, Susan Kirkpatrick Mayor Kingston Woods PUD - Preliminary, #58-91 January 27, 1992 P & Z Meeting Page 4 4. Transportation Primary access to this site will be from West Horsetooth Road at Seneca Street (extended). All interior streets will be dedicated public streets with local classifications. Seneca Street, a local street at this location, will be extended south from its existing location in the Wagonwheel Subdivision. Seneca Street will eventually, as development occurs, continue south of Horsetooth Road, where it is designated as a collector street, and connect to the existing sections of Seneca, north of Harmony Road. This project proposes a 375' offset to the west for Seneca street south of Horsetooth Road. This is due to the existing location of the Pleasant Valley and Lake Canal channel, the ditch crossing of Horsetooth Road, and the stand of mature trees on the site. The City Transportation Division has reviewed the Traffic Impact Analysis and finds that the proposed off -set will be acceptable. Any necessary striping of Horsetooth Road,: for turn lanes, will be addressed on the Final Utility Plans. 5. Storm Drainage Runoff flows for a majority of the site will be routed to a detention pond in the northeast corner of the property. The overall flow pattern is from southwest to northeast. Preliminary drainage, grading, and erosion control plans have been reviewed and accepted by the Stormwater Utility. Minor revisions are expected before final approval can be granted. Staff finds that the proposed project meets the Residential Density Chart and the applicable All Development Criteria of the Land _ `Development Guidance System. Staff recommends approval of the Kingston Woods PUD- Preliminary, #58-91 with the following conditions: 1. A final landscape plan be submitted showing the location and type of street trees being proposed for Horsetooth Road and Seneca Street. 2. That the pillar issue be resolved prior to final approval.
