We have made a preliminary review of the Fossil Creek Commercial P.U.D. located south of Fort Collins in the SEk, Sec. 35, T7N, R69W• The plan incorporates approximately 43.5 acres for two major shopping com- plexes initially planned. Under the P.U.D. concept, 6.5 acres will be allocated to open and green space. The New Mercer Canal traverses through the center of the property and flows in a southerly direction. It hE; been proposed to abandon the existing open channel ditch structure and to construct a reinforced concrete box culvert (RCB) to accommodate the New Mercer Ditch flows as well as to intercept the storm runoff generated from the accompanying commercial development. A 4-foot by 7-foot RCB, nearly 2,300 feet long has been proposed under McClelland Drive, the main thoroughfare of the development. Because of the size and the depth of the proposed conduit, the following items present major consideration: • capacity • maintenance and access • ditch rerouting and easement • water quality Capacity The capacity is adequate for the 80 cfs irrigation requirements of the ditch company. Under the average daily operating conditions of 40 cfs, the velocity in the culvert is estimated to prevent siltation and sedimentation. Provisions should be made for overflow such that it can be directed in the same area of the ditch. ..RANCH OFFICES GLENWOOO SPRINGS STEAMBOAT SPRINGS LEAD'OEADWOOD O ILLON LAKE P O BOX 1206 O BJF 5220 G3 SHERMAN Pn R.T.-1. 1O BO%IITI GLENWDOO SPRINGS.

As you know a partnership of which :f. am the managing partner owns the property immediately north of Harmony. From indications I have seen on the preliminary plat of the land adjoining us to the north, it appears that the alignment of McClelland is such that i_t does not coinside with the most desirable align- ment from our point of view. The most desirable situa- tion I -or us would be to have the west :Line of McClelland Drive line up with our west property line. It appears that the present alignment of McClelland as it shows on the Troutman plan brings the .road onto our property =,ome- what east of what we would consider the most desirable alignment. Obviously if this forced us to leave a small strip of land useless on the west side of McClelland Drive we would not be willing to oblige in the contribu- tion of the right-of-way. I am sending copies of this letter to Morrie Rupel, Paul. Deibol.d and Milo Bunker in order to see if you can not get this corrected before it is too late. I would appreciate hearing back from you on this matter. Yours s. rpcerely, J.

As I indicated in that conversation, the City will be able to issue an "at risk" Footings and Foundations Permit for the Target Store, notwithstanding the fact that the improvements relating to water, sanitary sewer, and roads as well as the ditch relocation, all pro- vided for in the Subdivision Improvement Agreement have not been accomplished. As we discussed, an "at risk" Footings and Foundations Permit means that the City, in issuing the permit, is not giving its approval of the work being done under the permit, nor is it waiving any of the conditions required in the Subdivision Improvement Agreement. Rather Target Stores would assume any risk involved with installing the footings and foundation before the other improvements are finally in place and accepted by the City. If you are willing to accept the terms of this permit, then the City will be willing to issue such a permit to you. If you have further questions, please advise.

DRAINAGE FLOOD CONTROL AND OTHER WATER ORIENTED PROJECTS Re: New Mercer Ditch Relocation E}, Sec. 35, T7N., R69W. Fort Collins, Colorado We have reviewed the most recently revised plans for the ditch relocation as prepared by M and I Engineers, dated November 16, 1978. The ditch has been proposed to be realigned in an open channel adjacent to the west side of the C and S Railroad tracks. The ditch is bordered to the west by the Larkborough residential subdivision and by the Fossil Creek Commercial Plaza to the east. Present construction plans call for modifying the existing structure at Mail Creek, boring under the C and S tracks south of Harmony Road, open trench construction of a 54-inch RCP crossing Harmony Road, replacement of the existing Parshalll flume, and construction of a diversion structure with headgate and cheek structure. Water will be deliverd to the existing 18-inch irrigation laterals at the present point of diversion on the existing ditch. Construction of the lateral through the Fossil Creek development necessitates a second bore under the railroad tracks. A 12-inch dewatering line will be laid parallel to the open ditch for most of its length. A cutoff trench !is proposed to reduce seepage to the existing ditch route at the upstream end of this project. The existing ditch is proposed to be abandoned and filled. Ditch Capacity The ditch has been designed for a capacity of 80 cfs. Plans indicate a depth of 2.9 feet for this flow with resulting velocities ranging from 2.4 to 2.8 feet per second. Several test holes, drilled in November by Empire Laboratory, show non -irrigation season water levels at or near the proposed channel invert. In addition to the '12-inch dewatering line, the ditch will be overexcavated and lined with clay where required in order to reduce groundwater inflow to the BRANCH OFFICES GLE Nw000 aFRINGS aIEA NBOAT EP PINOS LEAD/DEADW000 .PEN DILLON LIRE P O ROZ 1386 P.O BOX S}}O .] .MERMAN P D FIG.

Stover New Mercer Ditch Relocation December 7, 1978 Page 2 ditch and to facilitate construction. Water levels in the area will gradually be drawn down as a result of the installation of the dewatering line and the dewatering system proposed in the Larkborough Subdivision. We recommend that a gravel filter be installed around the•12-inch perforated pipe to prevent clogging of the line. t Mail Creek Outlet Due to the velocity generated in the 54-inch RCP, it will be necessary to construct an energy dissipating structitrP at its outlet. The ditch should be riprapped downstream of this structure to prevent erosion. The proposed ditch will be constructed to tie into the existing cobblestone drop structure upstream of Mail Creek. We understand the area below the drop is eroded and in poor condition. A defined channel to Mail Creek should be con- structed. Riprap should be added at the existing structure to prevent further channel deterioration. An additional drop structure may be necessary below the existing drop, depending on the actual field condition. Two laterals take off from the existing cobblestone drop structure. These diversions are to be maintained in their current operating condition. Harmony Road Inlet Regular maintenance of the proposed trash rack at the inlet of the 54-inch pipe will be necessary to assure safe and proper function of the ditch system. Large debris such as shopping carts and tree branches can be expected due to the adjacent land use. Trash racks are an absolute necessity at both ends of the 54-inch pipe. This would help protect the ditch company from liability since the pipe would be an attractive nuisance to children playing in the area. If the ditch company does not want to maintain the proposed trash racks, we feel that it would be appropriate to have the developer set aside a perpetual fund for these cleaning operations. A 15-foot long riprap transition should be added at the inlet to protect the invert and ditch slopes. Check Structure We feel that the proposed check structure is not stable and offers inadequate protection from overturning due to debris buildup or piping. It is recommended that this structure be modified to include a spread footing and perhaps be widened to stick further into the banks. Since we are not structural engineers, we can not evaluate in detail the structural integrity or confirm the reinforce- ment design of the structures involved on this project. .r. William C. Stover New Mercer Ditch Relocation December 7, 1978 Page 3 Larkborou h Subdivision A 2 -inch RCP detention pond outlet is proposed to discharge to the New Mercer Ditch. The tributary area to the west historically drained to a 20-inch pipe located under the railroad tracks approximately 150 feet north of the proposed outlet and discharged west of the existing ditch. The detention pond for the subdivision is located on the eastern property boundary adjacent to the proposed ditch. A detailed site drainage analysis of the subdivision was not undertaken as part of the ditch relocation study. However, rules of thumb developed from previous area site drainage studies were applied. The pond volume of 15 acre-feet seems adequate for 100-year detention storage. The pond is proposed to have a permanent water surface; thus, the 15 acre-feet would be considered live storage available above the normal operating levels of the pond. it is recommended that the pond outlet be staged such that the full storage capacity can be utilized for all storm frequencies. Thl' will allow a storm less than the 100-year to discharge at slower rates. An extensive groundwater dewatering and French drain system is proposed for the Larkborough Subdivision. Apparently, intercepted groundwater flow will also be directed to the pond and eventually to the ditch. It should, be a decision of the Board of Directors of the ditch company whether to accept this groundwater or not. Ditch Inlet Due to the angle ofthe existing ditch to the proposed alignment it is necessary to riprap the ditch and its banks both upstream and downstream of the junction. A cutoff trench will be constructed to prevent seepage to the ancestral ditch. The cutoff should be tied well back into the existing ditch banks to contain any end run around the trench. Maintenance In order to facilitate ditch maintenance and to provide sufficient area for ditch clean -out, a maintenance access road should be constructed on the east ditch bank at the same elevation as the road shown on the west side. A 6-foot chain link fence will be constructed on the west bank. Access to the ditch is proposed at Harmony Road. An area for vehicle turn around at the north end of the project should be provided. Construction Construction of the ditch should proceed from the downstream end. It is necessary that construction be completed during the non -irrigation season because of reliance on the ditch by farms during the season. . William C.

We presently have a contractor under contract to build a segment of the Warren Lake Trunk Sewer across the property between College Avenue and the C & S railroad tracks. We estimate that this should be completed within the next 45 days. There is another segment of the sewer to be built east of College Avenue. We expect to open bids on this segment on February 9th and award bids on February 20th. The construction on this re- quest should be complete by the end of April. If properties in the Fossil Creek PUD require service prior to this date, we will plug the trunk sewer west of College and pump from a man- hole. We hope this clarifies our schedule for you.

Drake Road Fort Collins, CO 8052_5 T Re: Target P.U.D. within Fossil Creek Commercial Plaza Dear Mr. Bunker: Pursuant to our meeting with the City Attorney and representatives of Target Stores on Thursday, January 25, 1.979, and your telephone request of Friday, January 26, 1979, we wish to express the City's position as follows: 1. The City would prefer that storm drainage being released from Fossil Creek Commercial Plaza be directed into the proposed "McClelland Drive Interceptor Storm Sewer". This drainage plan is shown on the site plans for Target P.U.D. and LaBelles P.U.D. and the utility drawings for Fossill Creek Commercial Plaza which were approved by the City Engineer in November, 1978. 2. In the event an agreement is not reached between the various landowners for the construction of the McClelland Interceptor Sewer and construction has not begun on the sewer by March 1, 1979, the City will review revised storm drainage cal- culations and plans for the Target and LaBelles P.U.D.s and the Fossil Creek Comrercial Plaza„ 3. The City will consider the following items in its review of the revised calculations and plans: a) The capability of the existing 24-inch diameter R.C.P. under College Avenue (to the East) to handle the revised discharge of Targets and LaBelles. b) The Developer's satisfactory solution of the disposition of the drainage West of McClelland Drive and East of the railway. c) The effect of drainage directed through the 24-inch diameter R.C.P. on the subdivisions presently being considered East of College Avenue. d) The effect, if any, on any drainage which might be directed to the 24-inch diameter R.C.P. from the Larkborough Subdivision West of the railroad. 4. An agreement will be required of the Developer to participate in the cost of constructing the McClelland Storm Sewer when it is required. We trust this answers your request and reiterates the City's opinion that the McClelland Storm Sewer appears to be the most satisfactory solution to the storm drainage for that portion of Section 35 east of the railroad. Sincerely, �) Donald M. Parsons City Engineer 100% Recycled Bond Mr. William C. Stover August 31, 1978 Page 2 Maintenance and Access It is recommended that a minimum of five clean -out manholes be installed at intervals of not less than 500-feet and at any change of direction. Large debris, such as tree limbs, which accummulate in the culvert will be diffi- cult to remove and may necessitate cutting before passage through the man- holes. A further concern of large debris removal is the proposed location at the street. The culvert easement should be made available to provide access for repairs and maintenance without hindrance to traffic. It is our understanding that the ditch in this reach has high accummulations of debris and silt. The grate at the culvert entrance should be installed at a slope of no less than 3 to 1, preferably at 4 to 1 to facilitate debris "riding -up" the grate to keep the culvert free flowing. A safety lock should also be added for protection. Agreements for maintenance of the culvert, the inlet and the outlet should be made with the appropriate entity for cleanup and debris removal on a weekly basis (luring the irrigation season and after every storm to assure proper function of the trash rack and prevention of blockage at the entrance. Sharp angular bends proposed for the culvert should be replaced with smooth curves with a minturn radius of 150-feet to prevent sediment deposits and debris blockage. Clean outs should be provided particularly at these points. To provide a continual flow line of the existing open channel canal, to the box culvert, it is recommended that the invert of the box culvert be set at the normal bottom of the ditch to assure future opportunity for sedimen- tation cleaning. Riprap should be placed at the culvert entrance and exit to provide pro- tection to the existing ditch from undue scorn and erosion. Ditch Rerouting Because of the heavy reliance by farms for irrigation water during the season, it is necessary to require that construction be completed during the non -irrigation season from October to May, Side slopes for the construction route should be set at a 3 to 1 minimum. tme-17 1 CI I Y OF FORT l OI L I N S P.O.

As you are aware, only two portions of the proposed McClelland Drive interceptor storm sewer have been installed to date. Those sections being approximately 340 lineal feet on the Target site and that sec- tion across Troutman Parkway. Therefore, the storm sewer is not functional in its present condition. As it is undesireable to have a crosspan across Troutman Parkway at College Avenue, it was necessary to intercept the existing drainage flow from College Avenue at the inlets on Troutman Parkway. Once the existing curb at this location is removed all of the drainage on the west side of College Avenue from the high point near the Prime Minister Restaurant to Troutman Parkway will pond in the intersection at Troutman Parkway. This water will build up to a depth of 82 in- ches before it would flow to the south on College Avenue. Because it appears that the McClelland Drive interceptor storm sewer will not be installed prior to Target's or LaBelle's opening, a temporary drainage system will be necessary. One alternative is to pump the stormwater from the manhole located on the south side of Troutman Parkway. The most cost effective method would be to pump directly into the curb and gutter on College Avenue. The water would then gravity flow south to the inlet which presently accommodates this drainage. The concern with a pump system is the constant maintenance, particularly in the winter season. Milo Bunker August 7, I'_979 Page 2 Another alternative would be to connect the two sections of the storm sewer presently installed and drain into the southerly man- hole on the Target site. The Target Store has installed a tempo- rary pump i_n that manhole which pumps into the existing 24 inch drain across College Avenue. Of course, this would require an arrangement: with Target for pumping expenses and maintenance. However, the advantages of this alternative are that the pump is already installed and Target will have employees onsite daily who can check and maintain the system. The disadvantage being the additional cost to connect the two sections of storm sewer. If I can be of further assistance in this matter, please contact me. Sincerely, M 6 I, INC. Lloyd G.

As we discussed at the meeting, the acceptable solution for tempo- rary storm drainage from the intersection of Troutman Parkway and South College Avenue would be the installation of a sump pump in the McClelland Interceptor Storm Sewer manhole located directly south of Troutman Parkway. The stormwater would then be discharged into the curb on College Avenue and gravity flow south to the exist- ing 24" drainage pipe across College Avenue. I have investigated pump specifications which would be acceptable for the temporary situation and provide safe conditions for traffic. It is recommended that a Peabody -Barnes Model 4SE201 or acceptable equiva- lent be used. This is a 2 horsepower, 4" pump which will pass solids up to 3" size. It will require a 230 volt single phase electrical connection and 2 mercury float switches for automatic control. The pump has a capacity of 375 gallons per minute under a 15' head. I have contacted Jim McLemore of McLemore Pump and Equipment Company, Denver, Colorado, Phone: 371-5730, for pump curves and manufacture's data. I will forward that information to you upon my receiving. Should you de- sire to talk to him personally, please do so. Mr. Maurice Ruppel, Development Engineer August 17, 1979 Page 2 In the event of a high intensity storm or malfunction of the pump system, stormwater could stand in the intersection as indicated on the attached sketch. The maximum depth of water would be 0.5' at the southerly catch basin, however, the intersection would be use- able for normal traffic. With the pump proposed the intersection would be totally drained in approximately 46 minutes. Should you desire further information on this matter, please contact me.

Box 580 Fort Collins, CO 80522 RE: New Mercer Ditch Relocation Sec. 35-7-69 Dear Mauri: This letter is submitted, per Milo Bunker's request, as an explanation of criteria and specifications for installation of a vehicular crossing on the relocated portion of the New Mercer Ditch in Section 35-7-69. It is proposed to install a corrugated steel pipe -arch with an 81" span and a 59" rise at station 36+00. This is di- rectly south of the rip rap as shown on Sheet 5 of the draw- ings for the project approved by the City Engineer February 20, 1979. The culvert is 14 gauge steel with 3" x 1" corrugations. It is designed to withstand an H2O loading. Installation in the location specified will provide approximately 12" of cover. The length of culvert to be installed is 30 lineal feet. It is recommended that the pipe be backfilled with on -site clay soils and compacted to 90% of Standard Proctor Density ASTM D698-70. Mr. Maori Rupel July 29, 1980 Page 2 Hydraulically the culvert is capable of carrying approximately 170 cfs. This is for inlet control and assumes a headwater depth in terms of arch rise equal to 1.0. Should you need additional data in this matter, please contact Milo Bunker of myself.

February 20, 1981 r ' `'F' Mr. Maurie Rupel 95s, i Engineering Department City of Fort Collins Post Office Box 580 Fort Collins, Colorado 80522 Dear Maurie: TELEPHONE AREA CODE 303 462-4322 r I have on occasion represented the owners of the Fossil Creek Commercial Plaza. They have contacted me with reference to a matter concerning this subdivision. Their property adjoins pro- perty which belongs to George Holter and Ezera Betz. The Holter- Betz property has been subdivided and the City has approved the plat of the subdivision. I also understand that utility lines have been extended from McClelland Drive across the Fossil Creek Commercial Plaza Subdivision into the Holter-Betz property. Milo Bunker who has been the agent for the owners of Fossil Creek Commercial Plaza tells me that at the time the plat of Fossil Creel, Commercial Plaza was approved by the City there was an agreement to withhold dedication of one foot on the north end of McClelland Drive. I have reviewed the plat of Fossil Creek Commercial Plaza and find that there is an express statement indi- cating that that one foot is not dedicated by the plat but is sub- ject to a separate instrument. As far as I have been able to determine there is no general dedication of McClelland Drive across the north one foot Fossil Creek Commercial Plaza. Assuming that this is correct, it would appear that the City does not have any authority for extending utility lines or the street across this property. The reason for withholding this one foot was the refusal of Mr. Holter and Mr. Betz to participate in the cost of relocating the New Mercer Canal as it crossed both properties. Since they did refuse to participate in the cost the owners of Fossil Creek Commercial Plaza bore the entire expense and the relocated canal was placed entirely on property provided by them. The one foot was held back in order to insure that the Holter-Betz property would not unreasonably gain from the development of the Fossil Creels Commercial. Plaza without paying its fair share of the relo- cation costs. Mr. Maurie Rupel February 20, 1981 Page Two In view of the above I have been asked to notify the City that the owners of Fossil Creek Commercial Plaza do not consent to the installation of utility lines or the extension of McClelland Drive across the north one foot of Fossil Creek Commercial Plaza. Any lines so installed shall be removed unless adequate arrange- ments are made to reimburse the owners of Fossil Creek Commerical Plaza [or the expense they incurred in relocating the ditch. After you have had a chance to investigate this matter I would appreciate it if you would give me a call so that we can discuss it further.

First it com- pletes the projoct with the engineer who desig:eJ the drainage facilities and keeps him the responsible p*rtv for the desicn. After certification the engineer cannot say that the improvements were not ccnstructed according to his plans. Secondly the certi- fication provides the assurance to the City that everything will work. The qity does not have the staff do the certifications itself. % The certification involves more than the information that Earl presented from the contractor. Those were only as -built eLe- /ations not accurately located (dimensioned) on the sketch.

Several decisions were made at this meeting regarding the construction to provide water and sewer service to the developing area. The City is prepared to let a bid for construction of the necessary portion of 24-inch water transmission main in Horsetooth Road (2030 lineal feet) with tentative com&etion in March Z979. The City is also designing the remainder of this transmission main to the tie into existing construction on Shields Street north of Horsetooth and to a point ,just east of College Avenue on Horsetooth (5440 lineal feet) with plans ready for bid spring 1979. Fossil Creek is developing ahead of most of these properties and conse- quentZy needs service first. The property owners of Fossil Creek and Lark Borough w&Z cooperate to construct the 12-inch D.I.P. main from College Avenue through Lark Borough to its northern boundary. The owner of the unpZatted portions of Park South will provide an easement through this parcel as well as through the platted portion of this property. Because of the pressing need for service in Fossil Creek and Lark Borough and the slower timetable envisioned for deveZopment of Park South, the City will cause to be designed and constructed the 0-inch main through the Park South property on a cost reimbursement basis. The City will obtain the crossing permit from the C & S Railroad. The alignment and timetable for future extension of this water service line east of College to an eventual tie within the Landings subdivision is largely dependent upon the rate of development of the South College Properties. Sewer service for these areas will be supplied from two different locations. A Z2-inch trunk is ready for bid which will extend service to the west bank of the New Mercer Canal, with capacity to serve the Warren property and Park South. Developers, Ct ners and Engineers of South CoZZege Avenue September 2P, Z978 SPA The City is a'esign.ing the 2Z-inch extension of the warren Trunk through the FossiZ Creek subdivision to the west side of the C & S right-of-way (through Cary Cooper at Hogan & OZhausen). This sewer should be ready for bid witYiin 6 to 8 weeks. The Tark Borough deveZopment wiZZ design and construct this tr<<nk through their property with oversizina paid by the City. After suitable aZignment has been determined the remaining portion of this trunk east of CoZZege Avenue through the ;Vest property the City will cause I o have designed (Hogan & OZhausan) and constructed this remaining Zink to minimise any delay of service to Fossil Creek and Lark Borough. The Creager FZaza property wiZZ be serviced by a north fZowing sewer into the Horse tooth Trunk. The Hotter and other properties between FossiZ Creek and Creager Plaza can be serviced bu either, with further investigation of the most pref'erraN e route Beira assessed the next few days.
