HomeMy WebLinkAboutCORRAL BUSINESS PARK PUD - Filed GC-GENERAL CORRESPONDENCE - 2003-07-31THE CORRAL BUSINESS PARK: STATEMENT OF PLANNING OBJECTIVES The 33 acre site of The Corral Business Park is located east of The South 13 Commercial Subdivision - approximately 650 feet east of South College Avenue - and is adjacent to the Fossil Creek Meadows and Huntington Hills Planned Unit Developments. Although located in an area of new development, the site has many of the constraints of an in -fill project. Surrounding subdivisions, an irrigation ditch, and the Fossil Creek Flood Plain have limited access to two existing connections to College Avenue; Caji ]Drive and Smokey Street. Both streets are internal streets in the South 13 Commercial Development, meaning that all uses locating in The Corral must pass through South 13 to access their properties. Topographic conditions have significantly limited the site's visability from the north, east, or south. The above conditions indicate that the types of land uses able to locate on the site are somewhat limited. It is anticipated that the appropriate land uses will include: - Greenhouses and Nurseries - Warehouses and Storage - Sales/Rental and Repair - Construction Services Generally, these are uses that need convenient access to a major roadway (U.S. 287), but do not require high exposure to highway frontage, and are not employee intensive (typically 6 to 12 employees/acre). The proposed plan seeks to accommodate the anticipated uses in a well planned, business park environment. Substantial landscape screening is proposed adjacent to neighboring residential developments, service areas and loading zones will be kept away from public streets and out of view from adjacent properties, and the streetscape is heavily planted. The proposal. is consistent with the City's adopted Land Use Policies regarding land utilization, growth management, and location of transitional land uses. Phase One (].4.6 acres) is expected to provide approximately 175 jobs. When completed, the Corral is expected to provide employment for up to 400 persons. Development is scheduled to begin in late 1984 or early 1985 and continue through 1992.

Collins, Colorado Dear Donnie, Z OF II ENGINEERING CORPORAT[()SHEARN We are writing in response to the written comments concerning the grading and drainage plan and report for Lots 7 & 8, Corral Business Park dated November 24, 1999. Written Comments • The cover letter for the report is signed and stamped. • The grading you refer to is to be covered with riprap. Therefore, the need for 3:1 slope should no longer apply. We have not changed the grading in this area for this reason. • All recorded easements are included with this submittal. • A detail of the valley pan is included on sheet 2. • A note is added to the grading plan and the site plan indicating that no trees are to be planted in the swale along the south property line. • We discussed the 81 efs (Q 100) issue with Basil Harridan prior to our last submittal. It was agreed that the design flow for the offsite swale would be 1.33* Q100 and that we would request a variance from the requirement that the design flow be 1.33*Q100 for the very eastern end of the swale (Section Bl-B1). This is documented in the variance section of the report. There is no need for additional documentation. • Calculations for the hydraulic grade line are included in the appendix of the report. • All appropriate attachments are now included in the drainage report. We apologize for this oversight. Plan Redlines • All of the survey data obtained for this site is based on the benchmark shown on the cover sheet. This survey data was completed within the last 8 months. We do not wish to change the benchmark at this time. 4836 S. C011ege, Suite 12 Ft.

Collins, Colorado 80521 Attn: Glen Schlueter Re: Lot 2, Corral Business Park P.U.D. First Filing; Ft. Collins, Colorado Dear Mr. Schleuter, Lot 2 was considered in the original Final Drainage Report for Corral Business Park P.U.D. First Filing prepared by RBD Inc., Engineering Consultants; Dated July 30, 1984; RBD Project No. 065-001; City Engineer approval date 06/25/85. The platted site area of lot 2 is 23,226 square feet (0.533 acres). Recently, a P.U.D. Minor Amendment has been approved by the City of Fort Collins which allowed additional flexibility in the final design of the site. The approved Minor Amendment is on file with the City of Fort Collins Planning Department. Lot 2, Corral Business Park P.U.D. was later incorporated with the final drainage facility design for Corral Business Park with OD's Sports Crossing when OD's Sports Crossing replatted a portion of Corral Business Park P.U.D. First Filing. Lot 2 was again considered with the "Onsite Grading, Drainage and Erosion Control Plan" and the "Final Drainage and Erosion Control Study for O.D.'s Sports Crossing Soccer Facility" for OD's Sports Crossing prepared by RBD Inc., Engineering Consultants; Dated March, 1996; RBD Project No. 684-001; Director of Engineering approval date 05/08/96. The following is a brief summary of Lot 2 drainage components identified from the "Onsite Grading, Drainage and Erosion Control Plan" for OD's Sports Crossing: a. A portion of Lot 2 is located in sub -basin 2A as delineated on the "Onsite Grading, Drainage and Erosion Control Plan" for OD's Sports Crossing (sheet 4 of 7). Sub -basin 2A represents a runoff coefficient of 0.80 for a fully developed site (See attached Sheet 8, Form SF-2 of O.D.'s Final Drainage Report). Runoff from this sub -basin is conveyed directly through the OD's parking lot in a blanket access, drainage, utility easement to Detention Pond A. b. A portion of Lot :2 is located in sub -basin 4E as delineated on the "Onsite Grading, Drainage and Erosion Control Plan" for OD's Sports Crossing (sheet 4 of 7). Sub -basin 4E represents a runoff coefficient of 0.85 for a fully developed site (See attached Sheet 8, Form SF-2 of O.D.'s Final Drainage Report). Runoff from this sub -basin is conveyed to the existing borrow ditch on the north side of Smokey Street. c. Refer to the Drainage Report for the OD's Sports Crossing; Prepared by RBD Inc, Engineering Consultants for additional detail. 4836 S. College, Suite 12 Ft.

Collins, Colorado Attached is a copy of the O.D.'s "Onsite Grading, Drainage and Erosion Control Plan" for immediate reference. The drainage basin line has been adjusted with the final design of Lot 2. The O.D.'s drainage report considered approximately 0.29 acres of Lot 2 contributing to the O.D.'s site and Detention Pond A (Sub -basin 2A). The actual area contributing to the O.D.'s site is approximately 0.37 acres based on the final design of Lot 2. The total contributing area to Detention Pond A is 3.14 acres. With the adjustment of the drainage basin line through Lot 2, there is an increase in contributing area to Pond A by 0.08 acres, which will have an insignificant impact on the maximum water surface elevation of Pond A. The O.D.'s drainage report considered approximately 0.24 acres of Lot 2 entering the street system and flowing easterly in Smokey Street. The actual area contributing to the street system is approximately 0.16 acres based on the final design of Lot 2. With the adjustment of the drainage basin line through Lot 2, there is a decrease in contributing area to Smokey Street by 0.08 acres, which reduces the offsite flow into Smokey Street. If you have any questions concerning the final drainage design for Lot 2, Corral Business Park P.U.D. First Filing, please call at (970) 226-5334.

Box 580 Fort Collins, CO 80522 Dear Elaine; Attached are three sets of prints of The Corral PUD, Phase One Final Site and Landscape Plans. The plans have been revised, as we discussed, in response to staff comments. The phasing of off -site street improvements to Smokey Street will be done as required on the approved Master Plan; When building permits have been issued on 40% of the total of Phases One, Four, and Five (see attached memo on traffic impacts). Phase One comprises less that 40% of that total, and can therefore be built out prior to the need for those improvements. The design for required improvements to Smokey will be included with final plans for the next affected phase of development. Signed filing documents, PMT's, colored plans, and ten sets of prints will be given to your office by June 14th. Thank you for your help in the review of this item.

Request for a variance from the City of Fort Collins Standard that all open channels be designed to convey 133% of the Q100 for the offsite channel that will be constructed on the Hahn property. e. The original report prepared for the entire Corral Business Park by RBD indicated that the Q 100 for the offsite channel was 81.0 cfs. The design flow would therefore be 107.73 cfs. f We have determined that existing upstream topography has reduced the contributing area to the channel. Refer to the drainage and erosion control report for additional detail. g. We have determined that the Q100 to the east end of the channel is 25.91 cfs. h. The majority of the channel (Section B2-B2) has capacity of 118.69 cfs. i. The eastern end of the channel (Section Bl-B1) where the depth is reduced to 1.25 feet has a capacity of 85.50 cfs. 4836 S.

Collins Stormwater Utility P.O. Box 580 Ft. Collins, Colorado 80524 Re: Lots 7 & 8, Corral Business Park; Ft. Collins, Colorado Dear Basil, I�I SHEAR ENGINEERING CORPORATION We are writing in response to the written comments concerning the grading and drainage plan and report for Lots 7 & 8, Corral Business Park dated 10/16/99. Our responses also correspond to Mark Oberschmidt's discussions with you on Friday October 29, 1999. A variance request letter is also included with this letter and the revised report. Written Comments The standard notes are now in accordance with Fort Collins Storm Drainage Design Criteria. They are provided on a cover sheet of the plan set. 2. An explanation of the drop structure is now included in the report. 3. Offsite topography is shown on the offsite drainage exhibit in the report. The basin delineation shown reflects what is actually happening today. The contours, as you noted, do not reflect current conditions. 4. Side slopes of the Swale along the south property line have been revised to maintain a 3:1 maximum slope. 5. Drainage easements are called out on all appropriate sheets. 6. The overall Q100 to design point 3 from the upstream area in the Business Park is now included in the drainage calculations. The site contributes less than 20% of the overall flow to the east end of Smokey Street. The overall contributing area, 1.35 acres, to the east end of Smokey St. (Sub -basin 3over) consists of the front parts of the existing commercial site west of Lots 7 and 8. A high point exists at the intersection of Smokey Street and Bueno Court. Refer to the offsite drainage exhibit in the drainage report. 7. The owner has obtained a temporary construction easements for construction of the retaining wall. He is in the process of obtaining a temporary construction easement for the off site channel. Copies of the completed easements are attached for your convenience. We will provide your office the easement documents for the channel as soon as we have them. 4836 S. College, Suite 12 Ft.

Grades along property lines are shown tieing into existing grades or the retaining wall in the case of the east and west property lines. The existing grades along the street are; based on survey data. The backs of walk elevations, at the surveyed points, are indicated on the grading plan. No additional topography is required in the street since no work in the street will be performed with this development. 9. The description of the offsite basins 01 —03 is included in the Final Drainage and Erosion Control Report. 10. A note has been added to the swale cross sections indicating that the landscaping placed along the south property line be placed at or above the estimated high- water mark in the swale. This note is repeated on the landscape plan. 11. Flow velocities along the offsite channel will not exceed 5 fps during the 100-year event. This is the permissible velocity for a channel, stabilized with grass mixture with a slope of 5.0%, in erosion resistant soils noted in Table 7-3 in the SDDC. We have specified that Mirafi Filter fabric be installed in the channel for additional erosion protection. Specifications for the fabric are included in the appendix: of the drainage report. 12. The offsite contributing area exhibit documents the limits of the contributing area for the offsite channel. This is also described in the report. We have indicated that the peak flow to the end of the offsite channel is less than that determined by RBD with their report for the overall Corral Business Park. The channel has the capacity to convey the 100-year peak flow determined by RBD (81 cfs). There is insufficient capacity in the lower portion of the channel (Section B1-Bl) to handle 133% of the Q100 as is stipulated in the SDDC. A variance request letter is attached and is included in the report. 13. Flow from sub -basin 3 flows into the street via the driveway. This is described in Section IV.A.6 in the drainage report. A curb cut is called out in the eastern driveway. A sidewalk chase in not required. 14. Erosion control items are shown on the plan as called out in the report. This includes a phasing plan for the erosion control. Drainage Plan Redlines The majority of redlines on the plans are addressed in the responses above. 2. We have noted on the plans the Tops and Bottoms of Wall (TOW and BOW) elevations. These are for grading purposes only. Actual bottom of wall elevations will be included with the structural details. Structural details of the retaining walls will be provided prior to issuance of building permit. Page 2
