This latest report has been revised from the original dated March 16, 1996 to address earlier city review comments. The most significant change from- the original plan is that site drainage improvements no longer require a major swale across the City's Salyer Open Space. Site runoff, including street flows from Hickory Street, will leave the site un-detained via a concrete pan to be constructed across Fourth Street. From there, flows will follow natural contouring across the Salyer Open Space. A 150' wide drainage easement will be obtained from the City of Fort Collins for this purpose. A description of the easement is included in this report. All design is in conformance with the latest edition of the City of Fort Collins' Storm Drainage Design Criteria and Construction Standards. ..�anpue��a��pr�rrrrriy� Very my You v® 0'. 27979 < Joseph P.

The parcel is just west of the Union Pacific railroad tracks, south of Hickory Street and north of presently vacated Fourth Street. Portions of the parcel will be deeded to the city for public rights -of -way along Hickory and Fourth Streets. The site is currently undeveloped. This report sums up the analysis that was undertaken to determine what, if any, impacts the proposed construction will have on the historical drainage patterns in each area. The report will address the following: 1.Site Descriptions 2.Storm Drainage A. Design Criteria B. Hydrology C. Conformance With Existing Master Drainage Plans D. Proposed Drainage Facilities 3.Erosion Control A. Erosion Control Measures It is intended that the recommendations found in this report become an integral part of the design and construction phases of the project. L I The property has been described as "a parcel of land being a portion of Block 15, the vacated alley therein, vacated Fourth Street and vacated Fourth Avenue, in Riverside Park of the City of Fort Collins, and other property in the SE 1 /4 of Section 2, Township 7 North, Range 69 West of the 6th Principal Meridian, in Larimer County, Colorado". The parcel is being re -platted as "Levon's Minor Subdivision". The area is undeveloped with no major physical features. There are about a half dozen mature trees... large diameter poplars. The trees will not be disturbed r by this development. The remainder of the site is local, native grasses. A public concrete bike/pedestrian trail borders the site along the west side (offsite), and the Union Pacific railroad tracks are along the east side. A partialy vacated Fourth Street forms the south boundary, and Hickory Street is along the north. A vacated portion of Fourth Street will be re -dedicated as public Right of Way as part of this project. The proposed building, (approximately 70' x 210'), will be about 80' south of Hickory Street, 20' from the west property line. Existing lot grading is at approximately .4%, generally from the north to the south. The north half of Hickory Street is paved and has vertical curb and gutter. The south half will be paved as part of this construction and will also include vertical curb and gutter and sidewalk. Fourth Street along the south property line is gravel now and will remain so. No street access is going to be provided to or from Fourth Street as part of these improvements. The only existing drainage improvements immediately adjacent to the site is the curb and gutter along the north side of Hickory. There is a curb inlet which drains the north half of Hickory and daylites through a CMP to the north. A 15" CMP has also been stubbed to the south side of Hickory in anticipation of the improvements to the south side of the street. A field investigation, however, reveals that the existing CMP discharging to the north has no well-defined discharge pattern and appears to drain directly onto Union Pacific R.O.W.. Fort Collins Stormwater Utility has asked instead of constructing a curb inlet and using the existing 15" CMP stub which was provided to collect street runoff from the south half of Hickory Street, that an alternative be investigated. One alternative, (which is proposed), is to construct a sidewalk culvert on the south side of the street on the Owner's property to collect a portion of the Hickory Street runoff. As designed, the length of Hickory Street being drained by the proposed sidewalk culvert is about 350', or .28 acres. There are no pronounced natural drainage features on the site. I The soils group making up the site is primarily clay loam according to the Larimer County Soils Survey by the Soil Conservation Service. A. Design Criteria The City of Fort Collins has prepared a Storm Drainage Design Criteria and Construction Standards (SDDC) which provides the basis for the analysis used in predicting storm runoff and the recommended drainage improvements. B. Hydrology The Rational Method is used to predict the amount of peak runoff. The 100-year return frequency was used in this report to predict major peak discharges, and 10-year storm is analyzed to predict minor flows C. Conformance With Existing Master Drainage Plans The FIRM Flood Insurance Rate Map prepared by FEMA ( Community Panel Number 08012-004-C, revised March 18, 1996) was consulted to determine flood plain boundaries in the area. The flood plains are indicated on sheet 4 of the utility drawings, and are also included in this report. In summary, the building site is not affected. D. Proposed Drainage Facilities ' Proposed drainage improvements consist primarily of street improvements to Hickory Street, a drainage pan across Fourth Street at the southwest corner of the property, and on -site grading. Hickory Street improvements include the sidewalk culvert in a sump condition which will direct runoff from the south half of Hickory onto the Owner's property. This runoff from Hickory Street, as well as site runoff, will be prevented from encroaching onto the neighboring Union Pacific property by the construction M of an small earthen berm along the east property line. Additional site grading will generally allow storm run-off to maintain sheet flow patterns. Concentrations of run-off will be avoided to keep run-off velocities very low, assisting in percolation and infiltration into the on -site clay loams. Existng conditions are flat and do not allow the customary 2% min. slope for earthen drainage, and there may be areas of standing water for brief periods after severe storms. The Owner is willing to accept this condition, and is asking the Stormwater Utility to grant a variance due to existing conditions. Because the fall is not available, there will not be any pronounced swales. Instead, water will be prevented from encroaching onto the Union Pacific property, and from over- topping Fourth Street and encroaching onto the Forest Service property to the south by the construction of a minor berm. The top of the berm will be at least 6" above an outfall drain pan constructed across Fourth Street. In the event of an extraordinary or prolonged storm event, runoff in excess of that amount capable of being absorbed by the soil or contained by surface irregularities will cross Fourth Street in the drain pan and follow historical drainage patterns southwards across the Salyer Open Space. A topographic survey indicates there is a natural, subtle depression across the Open Space that would discharge eventually to the Poudre River, about 1200 feet south. Maintaining existing historical drainage across the Salyer Open Space has been discussed among city staff of both the Stormwater Utility and the Natural Resources Department. By reviewing and approving this report and the Utility Plans dated March 16 (and revised October 14, 1996) for Levon's Warehouse and Office Building, the City of Fort Collins acknowledges that the continuance of historical drainage patterns is acceptable, and is in fact more conducive to the purpose and intent of acquiring open spaces than is the alternative of constructing an open channel across the Salyer Open Space. A drainage easement will be obtained ' from the City of Fort Collins to allow runoff to traverse the Salyer Open Space. In designing the drain pan across Fourth Street, allowance was made in the runoff calculations to provide for possible future development on the site which might account for additional runoff than that generated from the single building presently proposed. The calculations included herein assumed the equivalent of a future 18,900 sf building and 16700 sf of pavement. It is usually desirable to design drainage facilities such as this pan to pass the 100yr runoff. Because the proposed drain pan will carry moderate vehicular and/or bicycle traffic, it is proposed that a pan designed instead to convey the minor 10yr storm be used. In the interest of public safety and comfort, the Owner is requesting a variance to build this pan to pass the minor storm. The gentler longitudinal and side slopes necessary for such a pan would be much smoother ' and safer to both types of traffic. In the case of major flooding above the 10yr storm, the result would be the same as presently happens; overtopping of the existing road onto the Salyor Open Space. I I I I :• •► •► :• The SDDC outlines the causes and results of soil erosion due to wind and rain. Along with the requirements of this report and the erosion control plans, the SDDC shall be considered in it's entirety for guidelines to aid in preventing ' rainfall soil erosion. The SDDC will govern requirements and specifications for earth moving at the construction site. A cost estimate for erosion control measures is included with this report. A. Summary of Erosion Control Measures The following is a summary of the storm drainage improvements and erosion control measures that are to be observed during construction. GENERAL EROSION CONTROL NOTE The City of Fort Collins Stormwater Utility erosion control inspector must be notified at least 24 hours prior to any construction on this site. ■ . All required perimeter fencing shall be installed prior to any land disturbing activity (stockpiling, stripping, grading, etc.). All other required erosion control measures shall be installed at the appropriate time in the construction sequence as indicated in the approved project schedule, construction plans, and erosion control report. Pre -disturbance vegetation shall.be protected and retained wherever possible. Removal or disturbance of existing vegetation shall be limited to the area required for immediate construction operations, and for the shortest practical period of time. All soils exposed during land disturbing activity (stripping, grading, utility installations, stockpiling, filling, etc.) shall be kept in a roughened condition by ripping or discing along land contours until mulch, vegetation, or other permanent erosion control is installed. No soils in areas outside project street rights -of -way shall remain exposed by land disturbing activity for more than thirty (30) days before required temporary or permanent erosion control (e.g. seed/mulch, landscaping, etc.) is installed, unless otherwise approved by the Stormwater Utility. The property shall be watered and maintained at all tip during construction I activities so as to prevent wind -caused erosion. All land disturbing activities shall be immediately discontinued when fugitive dust impacts adjacent properties, as determined by the City of Fort Collins Engineering Department. r . All temporary (structural) erosion control measures shall be inspected and repaired or reconstructed as necessary after each runoff event in order to assure continued performance of their intended function. All retained sediments, particularly those on paved roadway surfaces, shall be removed and disposed of in a manner and location so as to not cause their release into any ' drainageway. ' . No soil stockpile shall exceed ten (10) feet in height. All soil stockpiles shall be protected from sediment transport by surface roughening, watering, and perimeter silt fencing. Any stockpile remaining after 30 days shall be seeded and mulched. . City Ordinance prohibits the tracking, dropping or depositing of soils or any other material onto City streets by or from any vehicle. Any inadvertently deposited material shall be cleaned immediately by the contractor.
