HomeMy WebLinkAboutCASA GRANDE PUD - Filed GC-GENERAL CORRESPONDENCE - 2003-07-31CASA GRANDE P.U.D. STATEMENT OF PLANNING OBJECTIVES The proposed plan for Casa Grande P.U.D. (formerly Wagon Wheel 3rd Filing) achieves many of the City's planning codes. Some salient features of the project include: 1. The project is in accordance with the City's master street plan, open space plan, the area master drainage plan and with all affected utility plans. 2. The plan proposes development of 134 attached condo- minium units designated as an "adult community" with sales targeted at the elderly market. A condominium association will be established for perpetual mainten- ance of landscaping common areas, buildings, driveways and parking areas. 3. A community meeting and recreation building will be included in the first phase of construction. 4. The project is contiguous to existing single family developments at more than 60 percent of its perimeter. 5. Care has been exercised in building siting and land- scaping to mitigate adverse visual impacts on the sur- rounding neighborhood. 6. The entire 20+ acre property is served from a single dedicated city street with private driveways serving the individual units. This represents a considerable on -going savings to the City in cost of street main- tenance. -- Utilities have been designed and laid in accordance with the existing street design. -- Design speed would become a critical factor if the street were lined with parked cars and traffic was such that two vehicles were to meet on the curves. The likelihood of this occurring is highly remote. At the wept horizonal curve (Phase 1), there is considerable off-st:r•eet parking provided near• the residential units and near the community building. At the east horizontal curve (Phase 3), there is a large passive open space provided on the west side of Laredo Lane, which is not likely to generate on -street parkers, and the residential units on the east side of Laredo have considerable off-street parking provided. Therefore, vehicles travelling through these curves are not likely to encounter extensive on -street parkers and, as such, will be able to use more of the street which will ostensibly increase the design speed of the curve. -- Since Laredo Lane may be perceived as being a "short: cut" from Casa Grande to Hickok, the 25 mph will make this "short cut" less attractive. The development on each side of Laredo Lane is geared toward elderly home -owners. It is the desire of the developer not to encourage through trips on Laredo Lane. Concern was expressed about the width of Seneca Street: as it proceeded south from the Hickok/Oregon Trail intersection. As part of their continuing responsibility for street construction in the Wagon Wheel Subdivision, it is Melody Homes' responsibility to construct a number of streets. In fact, Melody Homes has constructed the curb and gutter• on both sides of Seneca from Hickok/Oregon Trail south approximately 380 feet to the south property line of the Wagon Wheel Filings. This curb and gutter provides for a 36 foot street: which is the standard width of a local street. The Fort Collins Master Street Plan does not classify Seneca Street. Therefore, unclassified streets are considered to be locals. The Fort Collins Staff has said that perhaps Seneca should be a collector. The standard collector street width is 50 feet. Seneca only serves; the Wagon Wheel Subdivision and the proposed Kingstown PUG to the south. All streets intersecting Seneca within Wagon Wheel are 36 feet wide (Hickok, Oregon Trail, and Sam Houston Circle). Casa Grande Boulevard is built to 44 feet and connects Shields (an arterial) and Dunbar (a collector). Casa Grande i=_more likely to function as a collector than is Seneca. Based upon projected traffic volumes and its place in the street: network in the area, Seneca functions as a local Therefore, parked cars on Seneca Street are likely to be few, and spaced such that the street wi11 be able to function to its full 36 foot width. Given the above analyses, it is requested that the width of Seneca remain at 36 feet adjacent to Casa Grande PUG. This memorandum has provided additional information regarding the 25 mph posted speed on Laredo Lane and the recommended width of Seneca Street from Hickok/Oregon Trail to the south.

Detention Pond #2, Fort Collins, Colorado Dear Susan, Shear Engineering Corporation has reviewed the current as -constructed Casa Grande P.U.D. Detention Pond #2 data. Field data was supplied by Frederick Land Surveying. The data was gathered on Thursday, May 30, 1991. Our review of existing conditions indicate the following: 1. Generally, the current pond configuration and associated drainage improvements perforce adequately for the improvements made to date. The pond and outlet function in substantial conformance with the drainage design intent. 2. The pond requires (on average) approximately 12" of additional excavation over the entire area of the base of the pond to achieve the desired detention capacity and conform to all original design considerations. This will be performed at a later date in conjunction will final grading for individual units. ?. The south/southeast slope and the westernmost slope of the pond require further shaping and final grading. We expect the south slope to be formed with the final grading around Building G, which has just been completed. West pond slope shaping and final grading can also be done at this time. The southeasternmost slope will likely be completed with final grading for Building H, which has not been started as of the date of this letter. A copy of the current detention pond #2 configuration and existing contours, relative to the original grading plan, is attached to supplement this letter. Though the pond requires further attention, the design intent has been achieved. We understand that further pond verification may be required once final grading and shaping of the pond is performed.

Dear Mr. Schuster: On Tuesday June 11, 1991, Glen Schlueter and I met to discuss the letter from Shear Engineering concerning the storm drainage issues for the Casa Grande P.U.D. After discussing Mr. Shears letter and reviewing the approved utility plans, I visited the site and found the following items need to be addressed prior to the City releasing any further Certificates of Occupancy for this development. 1. Revise the overall grading and drainage plans to show the existing concrete pan adjacent to Laredo Lane and building Pad D, show the 12 inch ADS pipe in its correct location from Tract 1 to the detention pond, including inlet and outlet invert elevations. 2. Rough grade the detention pond bottom and side slopes to comply with the plans. 3. Regrade the area from the concrete pan under walk drain through Tract 1 to the ADS pipe. For your information I have enclosed copies of two photographs which show the erosion which has already occurred as the water tries to make its way to the detention pond. 4. Prior to the release of any Certificate of Occupancy for building H the pond and associated drainage facilities are to be built in its entirety, and these areas are to be certified by a professional engineer. As this development has been in varying stages of development now for several years, it is the City's desire that the storm drainage be completed as soon as practical per the approved utility plans. With the completion of`these facilities and with the City's acceptance of their construction the storm drainage then becomes the responsibility of the Home Owners Association. 281 North College Avenue • P.O.

I was asked about widening the deck for 3448-B, and the Board sees no problem with that. Dan discussed with me the location for air conditioners in units B and D. Cf course, there is really no problem for an end unit, but there is unanimous Board agreement for putting compressors in front for the center units* We all thank you for including input from the Board on these matters. As for the greenbelt in front of 3500 and 3460.. the crew has done much to fill in the excess -rain caused gullies, the spots where the grass seed did not take hold, and to improve the drainage - especially towards the east end; however, there is still standing water in many locations from the end of the concrete section of the drain to about the center of the greenbelt, I know that Dan said there was a four inch drop, and John also feel there is a drop, but almost everyone here who looks at it sees a slight rise. There has to be some explanation as to why hours after the sprinklers have run, residue water still remains. Perhaps a re -shooting will solve the mystery; therefore, next time you are up here, please take a close look at this area, and ask Dan to set up the transit and measure the drop every few feet' so that we can get this issue behind us and get the water where it should go. Your earliest consideration of this request will be appreciated so that if adjustments need to be made, John can attend to them before he returns to classes on the 26th. t; r\ ' ,A North of Laredo s front of Roush s 1 88 3A front of zvans ; 117 I �I v V Sincerely A.

Detention Pond #2, Fort Collins, Colorado Dear Mr. Schlueter, Shear Engineering Corporation has made final observations regarding the Casa Grande P.U.Q. Detention Pond #2. Our final observations were made on Tuesday, August 6, 1991. These oservations were made to determine that our concerns mentioned in our letter of May 31, 1991 had been addressed and if the concerns in the letter to Leo Schuster from Dave Stringer, Chief Construction Inspector for the City of Fort Collins, had been addressed. The following responses are in the order of the item of Dave Stringer's letter: 1. Grading and drainage plans have been revised to show the existing concrete pan and the actual location of the ADS pipe. 2. The detention pond bottom and sideslopes have been graded to our satisfaction. The pond substantially conforms to the plan. �. The erosion situation on Tract I between the concrete pan under the walk and the ADS pipe to the pond, has been corrected. 4. As constructed drawings of the pond are being submitted in conjunction with thI.s letter. Generally, Detention Pond #2 and associated drainage appurtenances have been constructed in substantial conformance with the Grading and Drainage plan and the approved drainage report. This letter is serves as our Engineer's Statement, as the Engineer of record, that Detention Pond #2 and associated drainage appurtenances have been constructed in substantial conformance with the Grading and Drainage plan.

College Fort Collins, CO. 80521 Dear Mr. Stringer Re: Improper drainage at Casa Grande Condominiums. Several months ago I contacted you about a drainage problem in two areas on this property. You checked the PUD requirements and in- formed me that the builder had agreed to certain conditions and that these problems would have to be corrected before he could obtain a certificate of occupancy for the next building. Subsequent to this meeting you were supplied with color photos showing -the problems. In the case of the East driveway entrance off of Laredo Ln. one photo clearly showed a considerable amount of ice over the driveway last winter. Nothing further will be done about correcting this. The problem of drainage through the lawn area from the sidewalk down through the holding pond South of the clubhouse has not been solved. There is a 21" plus drop from the sidewalk to the lower drain, however the first several feet from the sidewalk does not have enough slope to drain the upper portion. Water stands there all the -time. Either your survey crew or the Storm Drainage crew came out and checked the drop. Sure enough it coincides with that of the builder. Their report indicated that the drop meets the PUD requirements. How ludicrous can they get when they can see water standing in the area mentioned! Someone from the Storm Drainage department stated that there is nothing they can do with the builder since this is on private property„ REALLY! What difference does it make whether it is private or commercial property? If the PUD requirements have no validity then why have them at all? It appears that this is just another way of doing "busy work". And, the builders can do anything they want and know that they can get by with it. They continue receiving; the certificates of occupancy regardless. Si el Don R. Wilkerson cc: Bob Smith, Storm Drainage Susan Kirkpatrick, Mayor Ann Atari, Assistant Mayor Develo, •ent Services Engineering Department October 31, 1991 Mr. Don Wilkerson 3449 Laredo Lane Fort Collins, CO 80526 RE: Drainage at Casa Grande Planned Unit Development Dear Mr. Wilkerson: The intent of this letter is to reiterate the City Storm Water Utility and Engineering's position as it relates to the drainage in the Casa Grande development. As I discussed earlier with you and Mr. Grant, the drainage facilities have been constructed in accordance with the approved plan and the Developer's Engineer has provided the City with a letter of certification for the same. Even though the system does not function as efficiently as it could, the developer has complied with the applicable City requirements. Therefore, we can not pursue this ,matter any further. In response to your comments concerning the ice over the east driveway last winter, I believe this has been addressed with the construction of the drainage Swale and lot landscaping improvements adjacent to 3424 Laredo Lane. It was the intent of the original design to build a low area into the driveway which will allow the surface water to collect at this point, then flow into the detention pond west of 3424 Laredo Lane. It is my belief that what is constructed is what was intended by the design engineer. There may still be some accumulation of ice during the winter months at this point, but it should be less then last year. Apparently, there is some misunderstanding about planned unit developments as they relate to Storm Drainage improvements. The intent of a P.U.D. is to allow a developer more flexibility in the utilization and design of a property for development, allowing for more freedom in the overall scope of a project. Most P.U.D. drainage facilities are not maintained by the City and are built on private instead of public property. The City still monitors P.U.D. construction and requires the design engineer's certification that the minimum needed improvements have been built in accordance with the approved plans. But once the improvements are in place, and are constructed as per plan, concerns about inconvenience or maintenance should be handled by the property owners --the developer and or homeowners association.

Box 7)80 • Fort Collins, CO 80522-0 80 • (303) 721-it-..()7, Mr. Don Wilkerson October 31, 1991 Page Two With respect to the grade elevations that were taken from the concrete channel downstream to the inlet pipe, it is my understanding that the developer shot these elevations with Mr. Grant of the Homeowners Association and in fact regraded some of the area in an attempt to solve the standing water problem. Additionally, Mr. Schlueter with the City Storm Water Utility has talked with Mr. Terry Heyne who represents the developer and asked for their input regarding this issue. It is their opinion that they have tried to resolve the problem with the homeowners association and feel that no agreeable solution has been found which satisfies both parties. It is unfortunate that this matter has not been resolved yet. But as I stated earlier, the Developer has complied with the applicable requirements. Therefore, the resolution of differences between the developer and the homeowners association is a private matter in which the City cannot be of further assistance.

On May 2, 1985 in Rocky Mountain High School, the staff of the Department of Community Development conducted a neighborhood meeting on the subject planned unit development. The purpose of the meeting was to present the project and to hear comments from adjacent property owners. Property owners were con- tacted by writing. Joe Frank, Senior City Planner, attended the meeting and represented the City staff. Leo Shuster, Brian Sheer, John Freeman and Dan Herlihey represented the applicants. Approximately 16 adjacent property owners attended the meeting. The major issues that arose during the meeting are as follows: 1. Several residents were concerned about children at the intersection waiting for buses. Staff Response: This appears to be problem associated with the School District buses than with the project itself. The project should not impact this situation one way or another. 2. Many residents were concerned about the already existing low water pressure problem and how it would be impacted by the development. Staff Response: The low water pressure is an area wide problem. Plans are underway which should relieve this problem. For instance, the Rossborough Subdivision to the east will be installing some water system improvements that will increase water pressure for this subdivision. There are also larger system improvements in the area being planned for in the next few years. This proposal should not significantly affect existing water pressure. 3. Several residents were concerned about construction traffic from the development on Hickok St. and Casa Grande Blvd. Staff Response: Construction traffic will be routed along the future Laredo Lane to Casa Grande in order to avoid Hickok St. 4. There was concern expressed about the impact on turning movements at the Casa Grande/Shields intersection. Staff Response: The improvement of Shields Street is underway as it abuts the entire Wagon Wheel Development including installation of a signal at the Horsetooth/Shields intersection. The improvement to Shields Street will include, a median and left turn bay onto Casa Grande. The signal should provide better spacing of vehicles which should allow easier left turns onto Shields St. from Casa Grande. The future extension of Seneca Street to the south and the installation of another access point to the subdivision from Swallow Road should relieve this problem. 5. Is there the potential for a school crossing at Shields Street. Staff Response: This comment will be discussed with the School District. 6. Several residents questioned the impact of the first phase of development with only one access point of Hickok St. Several residents would prefer to see Laredo Lane installed at the beginning. Staff Response: The number of trips should not significantly impact the homes along Hickok Drive from the first phase of the project (forty units). Any further development should include the remaining portions of that street. 7. How will the applicants guarantee that the project will be for "older" adults as presented at the meeting? Staff Response: There is no guarantee as to the type of resident in the project. 8. Several residents were concerned about the variety of buildings and would like to see some two story elements along the public streets. Staff Response: The staff is also concerned about the variety of buildings in the project. See staff report for further comments. 9. Residents would like to see some variety in the building materials. Staff Response: Staff agrees. See staff comments for more details. 10. Will the units facing Casa Grande, Hickok St. and Seneca St. encourage parking on this street? Staff Response: The streets in front -of these units are designed to allow parking on both sides for the abutting single family homes as well as the proposed condominium units. Each unit is provided with a two car garage. In addition, guest parking has been provided. The staff believes that some parking will occur on these streets for short term and guest parking. However, this should not present any significant problems for the neighborhood. 11. Some residents would like to see single family homes built on the property instead. Staff Response: No comment. 12. Will the existing trees be maintained. They have created ice build-up problems on Casa Grande in the past. Staff Response: All existing trees will remain. They will be pruned to City specifications which should resolve some of the icing problems. The applicants have also submitted written responses to each of these comments. r- en W MEMOP.At',IDUM 0 0 a Cr N To: Leo Schuster Jo Fort Collins Staff • co CO Z CD CO From: Matt Delich� a J > Date: Tune 1, 1985 0 J Subject: Response to traffic comments. on Casa Grande PUD z w a a This memorandum addresses two specific traffic z related comments made by the City of Fort Collins Staff m concerninc, Casa Grande PUD. The comments refer to the r design speed of Laredo Lane and the width of Seneca Street south of Hickok. Concern was expressed that the design speed on the two horizontal curves on Laredo were at less than 30 mph. The Fort Collins Design Criteria and Standards for Streets allows a design speed of 25-30 mph for local streets. Use of the lesser, design speed must be approved by the traffic engineer. Laredo Lane has been designed with a centerline radius_ of 175 feet. This. is the approved design in the Wagon Wheel Filing Number 3. A centerline radius_. of 165 feet results in a design speed of 25 mph for a local street. The 175 foot radius results in a design speed of 26 mph. The requested z posted speed on Laredo Lane will be 25 mph. This is ?6 w percent i)f the design speed. Running speed, as z documented by AAC+HTO (1984), is typically 90-95 percent z of the design speed. At tow speeds and 1 ouJ Vol umeS, the u; W running speed often is very close to the design speed. Typically on high volume, high speed roads, the running v speed and design speed diverge significantly. • v zo It is requested that the City of Fort Collins a permit a posted speed of 25 mph on Laredo Lane for the LU o following reasons: a Q - The design speed is greater than 25 mph and generally within acceptable engineering practice. 3 � - The street design a.s proposed is identical to _ -< that approved in the Wagon Wheel Filing Number 3. This I— �- developer, in fact, does not own or control all the land Q necessary to make a change to a higher design speed. M
