Consulting Engineers October 18, 1974 Mr. Lloyd McLaughlin City Engineer's Office City of Fort Collins P. 0. Box 580 Fort Collins, Colorado 80522 Dear Lloyd: Utility Plans Hill Pond Second Filing We received the original drawings on this work back from your office on October 15, 1974 with the tracings not approved. Also, there was a note from you concerning the utility boxes sitting above grade at the intersection of Farmtree Road and Sheely Drive. Your note states that the Light and Power Department has looked at these utilities and that they feel they can be moved but at the developer's expense (estimated at $197) --- you further re- quested our investigating the matter and submitting a design for the intersection to provide adequate sight distance. The history of the project, as I remember it, is that the City has requested that Hill Pond extend Farmtree Road paving from the hill Pond Subdivision through Sheely Subdivision to the intersection of Sheely Drive all at Hill Pond's expense. We are assuming that the City will be installing a stop sign for Farmtree Road traffic at the "T" intersection with Sheely Drive. Don McClelland and I drove to the site and can see no major sight distance problem caused by the utility boxes. Further, would it not be reasonable to assume that if the City wants this road extended and the utility boxes are owned by the City and if the City is concerned about the sight distance that it would be the City and not the developer who would move their boxes to achieve the results they desire? Also, once the boxes are moved what happens to the trees and bushes around that intersection that could block vision over the years? 0111(1 "I I A<IH III IIUUI A • 1'.0.

Box 580 Fort Collins, Colorado 80522 Attention:. Mr. Dori Parsons Civil Engineer Re: Victoria Limited --Hill Pond Development Dear Mr. Parsons: Of Counsel: WINSOR C. MOORE I have reviewed Mr. Engemoen's letter of July 3, 1979, concerning the agreements reached between the City of Fort Collins and Victoria Limited at a June 27, 1979 meeting in your offices. The meeting was conducted to discuss and clarify various requirements concerning drainage improve- ments in the Hill Pond Development area as a result of the F.I.A. study and the City of Fort Collins Interim Flood Ilydrol.ogy Report for Spring Creek. I believe the following points were agreed to at our meeting: 1. The minimum requirement will be that the Developer provide for the passage of flood waters through its property pursuant to the current F.I.A. :.map and study as required by the CiLy's flood plain ordinance. If the F.I.A. map and study floodway is channelized and improved to confine the floodway, such improvements shall be designed and installed at the expense of the Developer subject to review and approval by the City. 2. So that planning and potential develop- Mr. Don Parsons Re: Victoria imited--Hill Pond Develop( nt August 2, 1979 Page 2 width to allow for the construction of an improved channel capable of passing the flood flows developed in the City of Fort Collins Interim Flood Hydrology Report for Spring Creek, which study includes drainage basin importation and additional drainage flows resulting from development in the upper portion of the Spring Creek Basin. The corridor width shall be determined by the guidelines proposed in the Interim Flood Hydrology Report for Spring Creek. 3. The City will continue its present study of the additional flows in the Spring CreeK basin as a result of drainage basin importation project and upstream drainage basin development. In the event this study determines that such drainage basin importation and up- stream interbasin development will result in flood flows in excess of the present F.I.A. map and study, channel improvements sufficient to handle such excess flood flows, developed pursuant to the guidelines of the Interim Flood Hydrology Report for Spring Creek, must be constructed with the cost for such improvements to be shared between the Developer, the City of Fort Collins, and upstream interbasin developers (at a minimum and potentially all developers) to the extent determined by City Council. The agreement relative to this last item was designed to allocate the costs of channel improvements associated wi.th e.cccss flood flows passing across Hill Pond property as a result of upstream interbasin development and drain- age basin importation. It was discussed and understood at this meeting that the complete data and facts were not yet available to conclude that the additional flood flows indicated in the Interim Flood Hydrology Report for Spring_ Creek in excess of the flood flows determined by the current F.I.A. map and study would occur. 4. It was further agreed that the City of Fort Collins, in recognition of the problem of ex- cess drainage caused by upstream inter -basin develop- r�r r TJ d i'vD n:'_�''r a po l. Cc - that, for 11LLJe �G Mr. Don Parsor Re: Victoria _imited--Hill Pond Developm .it August 2, 1979 Page 3 contain language concerning the excess drainage problem and an agreement that subdivision devel- opers would agree to share in the expense of down stream channelization on the basis of cost or by a development fee or charge. This policy was to be implemented immediately. The final method for distribution and assessment of these costs and ex- penses would be developed and as approved by the Fort Collins City Council. It was further discussed and agreed that planning and development could cormience within the Hill Pond area reserving as a maximum corridor for channel improvement the improvement channel corridor as determined by the Interim Flcod Iiydrology Report for Spring Creek. The minimum corridor for channel improvement would be that as required by the current F.I.A. map and study. As a fur- ther part of our discussions and agreements, it is intended and was discussed that any channel improvements would not bo commenced immediately or required by the City prior to planning and development in the Hill Pond area. If this summarization of our agreements and discus- sion is not accurate, please respond in writing.

Hallman The Hill Pond 2nd Filing P.U.D. is conceived to fulfill several objectives. The main objective is to establish an exclusive single family development within the flavor of the overall Hill Pond Master Plan whose orientation lends itself well to passive solar, custom home designs. As well as seeing the need for this sort of development in the overall Master Plan, using this single family as a buffer to the existing single family to the north seemed appropriate. Existing utilities governed the street layout. Active open space will occur in the flood plain area which is currently being designed as a "people place" with landscaping and bicycle paths for active recreational enjoyment. This plan will be submitted seperately soon as a comprehensive landscape plan of the entire floodway area. Pedestrian access to this space occurs between lots 33 and 34 through a 30' wide green belt area with sidewalk. Thank you.

Below please find responses to your comments dated June 26, 1980- The res- ponses are consistent with these discussed during the meeting with yourself and the engineers. If you do have any further questions, please do not hesitate to contact our office. X 1. Spring Creek will be improved to City Standards. Final engineering drawings are now being completed relative to the re-channelization of Spring Creek. These drawings will be submitted at final. ?(2. Existing flood plan is as shown on the submittal. iC 3. The g-'ade for Farmtree Road has been discussed with the engineering staff. Final design drawings will reflect an appropriate grade which is acceptable to the staff. x 4. Farmtree Road as well as River Meadows Drive have been reduced to a 28' Street width. Farmtree Road and Rivermeadows will be designed at 900. The applicant x will be responsible for signing of this intersection. X 6. The 50' ROi7 of Farmtree Road will be dedicated to the City of Ft. Collins by the current owners. As discussed, this area was not included in adjacent plats and as such is still owned by the original property owner. We have contacted them and they have agreed to dedicate this to the city or deed the property to h;r. Van Lear so that it can be dedicated.

All bearings shown on the submittals are based on the outer boundary as presented in the original plat of this property. An engineering review shows that the line bearing S OOo 17' 35" W, 116.67 is needed to close the plat and connect the adjacent plats. This is different than shown on the Spring Valley Plat as it never connected with the hrthur Sheely Subdivision. This line descrepancy will be corrected when the ROW discussed in Item (6) is resolved. Twoother interior angles on the north boundary line are off by o 00 00' 01" each. Again the bearings shown are consistent with those on the original plat. These descriptions will be resolved in final submittals. Relative to the current boundary dispute to the North, Mr. Van Lear has contacted property owners to the north and has informed them of the situation. To date, no comments have been received. It is the intent of the developer at this time to develop to the full extent of his boundaries. This is consistent with legal review. /Q0. All existing easements are shown.

I" Depzriment TO: Linda Hopkins, Planning Aide FROM: Dale A. Johnson, Civil Engineer RE: Spring Creek Floodwav Improvements,Hill,&nd 2nd Filing P.U.D. Comments: 1. If possib-e, the crossover structure" for the bicycle trail adja- cent to South Shields Street should allow for a minimum 50 foot radius. Perhaps a bridge slightly downstream that would span the trickle channel and float to one side during a major runoff event would be satisfactory. 2. Subsequent plans need to ensure the floor of the "7'-0" way under Shields Street" would be free of water during everyday operation. 3. The statement concerning cost sharing of the bicycle trail should be clarified in the following respects: a. The City is to share in construction costs of only the main trail. Construction of side paths is to be the developer's responsibility. b. The City share will be funded by the Open Space and Trails 7 year capital fund, not Fort Collins City Council. c. We need to know if the 3 homeowner associations plan to maintain the main bicycle trail. 4. Use of C.S.U.'s existing track on the east end of the project is subject to approval by C.S.U. A written statement of approval from C.S.U. should be required. 5. The alignment is considerably different from the proposed tempor- ary trail that is currently under contract for construction. Will a new right-of-way need to be established for this permanent trail? cc: Josh Richardson Randy Balok H. R.

These improvements will be constructed by Mr. Stevan Van Lear of Victoria Limited. As indicated on our drawings, a reinforced concrete headwall with three 48" diameter sluice gates is proposed to be installed in place of approximately thirty lineal feet of existing headwall and weir section. These sluice gates are designed to convey the 2-year design storm with a peak flow of 480 cubic feet per second. All other flows from larger storms will spill over the headwall section, as they do presently. A modification or addition to this proposed headwall section will be necessary to retain water upstream from the headwall at a designated elevation, as proposed in the landscape plans by Gefroh and Associates (these plans will be forwarded to you by Mr. Tony Hughes). This addition may take the form of a drop inlet intake or improved spillway over or adjacent to the pipe sections. We would appreciate your review and comments on these proposed alterations at the Arthur Ditch.

The topic of discussion was the vertical alignment of Farmtree Road at Hill Pond Single Family. When Hill Pond Single Family went through as a preliminary, there was some discussion and feedback from the City with regards to the slope of proposed Farmtree Road at Hill Pond. At that time, we told them when it came final that we would meet with them again. The City requires a maximum of two percent (2%) for two hundred (200) feet out of an intersection. However, when this standard is applied to Farmtree Road, the side slopes are approximately forty to fifty percent (40-50%). In addition, the amount of fill in this area ranges from three to seven (3-7) feet. The excessive side slope is a result of the existing homes built on both the north and south sides of this right-of-way. Therefore, the following designs and recommendations were agreed upon by the above people at the meeting. 1. We would maintain a two percent (2%) slope towards the west from the center line of Sheeley Drive for a distance of seventy five (75) feet. 2. We have agreed that we would maintain two percent (2%) grade for fifty (50) feet on either side of the P. C.'s for the ninety (90) degree intersection of Farmtree Road and River Meadows Drive. 3. We would maintain a four to four and a half percent (4-42%) grade between 'the ninety (90) degree intersection and the center line of Sheeley Drive with the exception of items 1 and 2. 4. We will :submit cross sections of Farmtree Road to better exemplify our design. It was agreed upon by the above people that this was a buildable design which could be lived with by the City. In addition, Josh Richardson brought up the idea of possibly eliminating sidewalk on one (1) side to leave some the vege- tation and trees intact. At this time, he did not know which side it would be and would be getting back with me. Rick Ensdorf then mentioned that if the sidewalk were eliminated on one side, the other side should be enlarged to better provide a sidewalk type access through Hill Pond Single Family area towards the west to Shields Street.

Due to the proximity of the project site, Hill Pond on Spring Creek 2nd Filing, we are asking for permission to release our storm drainage flows directly into Spring Creek. By routing the runoff directly to the Creek, we will be reducing the peak flows in Spring Creek. We are also in compliance with the Tri-Consultant/Gefroh Associates, Inc.

The owner has requested the street be narrowed as much as possible to increase the lot sizes in the project site. The City of Fort Collins planning department has given a favorable comment on the narrowing of the street which they feel will add to the planned unit development by adding square footage to the proposed single family lots. We generally feel that because this is a planned single family area, the size of the lots will be a factor in providing a pleasing development. By granting this variance and reducing the street to a 40 foot right-of-way and a 28 foot flow -line to flow -line distance, we will in turn provide the City of Fort Collins an improved single family planned unit development.

RE: "Hillpond" Arthur Ditch at Spring Creek Dear Bob: In response to our conversation on Thursday, December 11, 1980, concerning the alternate design of the spillway structure on Spring Creek at Arthur Ditch, we hereby request the design storm flow of approximately 480 C.F.S. be reduced and/or eliminated, and the three 48 inch diameter sluice gates, previously shown on our detail sheet for the "Hillpond" project, be eliminated. In lieu of the above, and if acceptable to the Arthur Ditch Company and Mr. Steve Van Lear, we propose to: 1. design a reinforcement to the existing spillway structure with rock and concrete, which will provide an inclined spillway to convey the trickle flow over the present structure; 2. locate a 24 inch C.S.P. with sluice gate at a low point in the proposed pond west from the spillway structure; and 3. design two weir structures at each end of the Arthur Ditch as it enters the proposed flood plan of Spring Creek. These structures are to be designed to allow water to enter Arthur Ditch for irrigation purposes, while eliminating flood waters to enter when the gates/boards are closed or in place. The north side structure will have a gate and pipe to discharge storm water when the ditch is not being used for irrigation. This design concept will be more efficient, as it will provide: 1. a tie in point for the shoulders of the proposed channel and thus, better protect the property west of the Arthur Ditch; 2. greatly reduce the vertical and horizontal fluctuations in the proposed pond; and CONSULTING ENGINEERS AND LAND SURVEYORS 7500 West Mississippi, Suite 30 0 Denver, Colorado 80226 0 (303) 922-1156 December 15, 1980 3N: 06780 City of Fort Collins ATTN: Mr. Robert W.

As you requested, the design flow requirement of 480 C.F.S. can be reduced or eliminated as far as the City of Fort Collins is concerned.

As you probably know, the plat for Hill Pond Second Filing was approved and recorded in May of 1974; however, the utility plans for this subdivision never obtained the final approval of the City. Prior to our approval of the utility plans at this time, certain revisions will be required to bring the subdivision into conformance with current engineering standards and specifications. The channel for Spring Creek will have to be improved in conjunction with the develoixnent of this filing. The Interim Flood Hydrology Report for Spring Creek, dated October 1977, should be used as the criteria on which the design of these channel improvements should be based. In addition, this development must provide a detention system which will detain the difference between the 100-year developed runoff and the 2--year historic runoff from the site, with a release rate not in excess of the 2-year historical rate. The engineering data and calculations re- quired to adequately evaluate the design for the channel improvements, detention facilities, and other storm drainage lines should be presented to the City Engineer for his review and approval in conjunction with the submittal of the utility plan revisions. Another question which must be addressed on this development concerns the size of the bridge on Spring Creek, and whether or not the City will participate in the cost of that construction. There is a problem with using Sheely Subdivision as access for construction traffic, and this may require the installation of the improvements on Fasmtree Road between Shields Street aril the Hill Pond Second Filing in conjunction with this development.

The variance for River Meadows Drive does pose sane problems. The City Engineering Staff supports the idea of a developer achieving the best use of his land and thus reducing the price per unit to the haneowner as long as it is not detrimental to the functions of the area. .To evaluate this variance we went to our Administrative Policies for 28 foot streets. River Pleadows Drive does maintain an ADT below the 750 vehicles/clay and does not provide through vehical travel. River Meadows Drive also does not provide for a connection between two arterial or collector streets. River Meadows Drive is a loop street but does connect two different city streets. The functions on the two city streets on which River Meadows Drive enter are fairly minor. This reasoning along with past statement made by the staff and giving recognition to your reasons for this variance, we hereby grant the variance. in the future request of this nature must address the merits of the project in respect to the guidelines and standards applicable. If you have any additional questions please contact me. I MEMO TO FILE Job No. 124-025-11 RE: Revised sewer services at Hill Pond single-family Date: June 16, 1981 on this day I was contacted by Larry Stanton to inquire with the City (Jim Hibbard) as to whether we could 'service the proposed single-family units from the existing eighteen (18") inch sanitary sewer. He inquired as to why in the past we did not recommend using this line. I informed him that it was the advice of the City not use it because it was to capacity and the condition of the line was questionable. Therefore, on our plans we recommend the use of the new Spring Creek interceptor sewer (21") which was deeper and had much larger capacity. A problem arose with the contractor (Jerry Palmer) Palmer Construction, in that the high ground water was making the cost of each sewer service extremely high. It was requested then to contact the city to inquire as to the tapping of the existing eighteen (18") inch. In talking with Mr. Hibbard he informed me that they had no problem under these circumstances to allow tapping the eighteen (1811) inch instead of the twenty-one (2111) inch as originally designed. I reminded Mr. Palmer of the thirty (30) inch water line and he in turn recommended that they go over the top of the existing thirty (30") inch water and encase then as per City of Fort Collins Standards for less than eighteen (18") inches of clearance. Therefore, in summary, due to the high ground water condition at Hill Pond single-family, we will be allowing the contractor as per acceptance by the City (Mr. Hibbard, City of Fort Collins Sewer and Water Department) to tap into the existing eighteen.(18") inch sanitary sewer as is feasible for each service line. The units to the south should have no problem as the interceptor line (21") is much lower and therefore, the sewer services will be able to maintain a minimum of three (3') foot of cover from the main to the lots themselves. In addition, the proposed sip; (6") inch water line will go over the top of each of the services, thus proposing no problem to the south. The units to the north will have no problem with the proposed six (6") inch water line as it will lie to the south of the services. Respectfully submitted, Rick R.

We are facing a severe problem in the maintenance of a farming operation on the south. cam,ous.

The headquarters of the farm operations will he roved from that location in the near future. The remaining piece of land which can be irrigated ise:.55-acre piece (in two fields) immediately west of the hospital and dairy. To cultivate this area will require moving !.arming equipment across the city. We would like to concentrate our pro3uction efforts on the agri7ultura_ campus and the north agricultural canous. We propose that the 55-acre piece be made available, beginning with the 1982 cropping season, to ARs for their research activities. The land is physically close to their headquarters and land they are currently using.

During our conversation with Dr. Young he indicated that he had a discussion with Mr. Van Lear about the drains and Mr. Van Lear stated he knew of their existence. I seriously doubt if he knew of their location, but perhaps he knew of the relationship of the gates located approximately 20 feet north of the discharge point into Sprinq Creek and the total drainage system. I belive it would be far more appropriate for the City to inform the developer, since the construction of the subdivision has to comply with municipal requirements and conditions. Upon my return to Denver, I contacted our engineer with Leonard Rice and Associates and requested that he run several tests at the time that you open up the drain on the west side of Shields. When you have your date set, please let me or Dr. Young know. It is a pleasure working with you on this matter and hopefully your investigation of the drain will provide sufficient capacity to carry off the seep water from the little duck pond located across Shields from the watts' property. Looking forward to hearing from you. Sincerely, RADQSEVICH & PAPPAS eor e E.

The schedule is based on at least a 7-day test being performed before backfilling on any of the structure above the sluice gate level. I feel that the schedule might be a little tight as shown, but the project should have no problem of being completed by the April 15, 1982 deadline. Attachment SUMMARY OF NEIGHBORHOOD MEETING 1904 Sheely Drive April 25, 1979 Approximately 40 neighbors gathered to hear about plans for this area. Stevan Van Tear, Broker, and Dan Wilson, representing Victoria, Ltd explained their developmen- concepts for Hill Pond. They emphasized their environmental interest, their concern for quality development of the area, and stated that they haven't any specific proposals for development at this time. There is quite a lot of work to be done for the floodplain designation adjoining Spring Creek, and both Steve and Dan ex'Dressed support for the bike paths planned by the city and explained that their support is financial as well as intellectual. At this time, only two streets are platted between Sheely Drive and South Shields; Farm Tree Road, which goes East from Shields and connects to Sheely just North of the Ware's house at 1801 Sheely, and River Meadows Drive which parallels Sheely starting behind the Ware's house and dead ends behind the Vail's house at 1925 Sheely Drive. Max Hoffman explained that he has purchased the 19 lots on the North side of River Meadows Drive, with the intention of building his own personal residence and developing the others as high quality patio homes. This follows the plat that was approved as part of the Hill Pond second filing in 1973. However, there are some problems regarding the utility approval and changes in floodplain designation (some of which Max learned about this evening) so he is not intending to break ground right away!! Victoria., Ltd. owns the remaining 26 lots in this plat. .Toe Frank and Bob Smith, representing the City of Ft. Collins explained that the sewer which is presently being laid across the fields is a sanitary sewer which is a trunk line needed generally for the Southwest part of Ft. Collins. It is part of a long-range plan and not specifically related to any current development plans. Joe also described the plans for Rolland Moore Park on Shields St. It will certainly be an addition to the area, and will be located South of Foothills Apts, behind the big yellow house,with 12 lighted tennis courts, baseball diamonds, etc. ••A•• ®1l M1010 11 ME� Date of Area of Work completion V Excavate north part of structure 12- 4-81 your footing 12- 4-81 /orm and pour north wall 12- 9-81 Backfill both 'sides of north wall to sluice gate 12-14-81 stall outlet pipe 12-15-81 Excavate south part of structure 12-16-81 Form and pour south wall 12-18-81 Backfill structure 12-29-81 Form and pour check structure 12-31-81 Install walkway 12-31-81 Install rip -rap 12-31-81 Backfill check structure 1-11-82 Final cleanup and approval 1-28-82 ram.-" �, •_.�.� r_� _. ��^.,.

PARKS AND RECREATION DEPARTMENT July 14, 1982 Steve VanLear 1013 Wind Trail Court Fort Collins, C0 80521 Dear Steve: The Parks and Recreation staff and Storm Drainage staff have again reviewed the plans that relate to the bike/jogging trail through Hill Pond. We feel that the construction of the floodway should accommodate the trail as shown on the landscape and site plans. The fact that the shelf or bench that would have accommodated the paved trail was not built during your floodplain construction is not the fault of the City. The site plan was referenced in the construction drawings. We would like you to have the bench established as the plans indicate. If you think this is not feasible, there are alternate solutions. On the east half of your floodway project, the trail can be built on top of the south berm leading to and from the bridge that is shown on the plans. Another solution would be to use approximately half of the width of the south berm, excavate 16" or 18" deep and build up the downhill edge. In any event we will have to use the bridge in the center of the project to cross Spring Creek, as shown on the plans_ We haven't discussed the bridle trail that is mentioned in our easement agreement. There is no accommodation for that either in the way the flood - plain is built. I know that we would both like to resolve this issue soon so that we can get on with our respective projects. Please let me know how you want to handle these situations. Sincerely, Randy Balok Supt. of Planning and Open Space xc H. R.

As discussed in the meeting between myself, John Payne, Mark Ingemoen and yourself, the reason for the less than desirable condition of the sub -base on the piece of street knovm as River Meadows Drive is due to the inability of the storm sewer to pass water. This is the result of the rise of the water surface elevation in the dam adjacent to the property. It was a design error by the consultants who prepared the plans for the dam in not considering the effects of raising the water level. This continuous 'level of water does not allow for the sub -base material to dry properly. The means by which we will eliminate this problem is currently under design by our office. We are looking at continuing a storm sewer to the east beneath Arthur Ditch emptying into Spring Creek. This will allow the water surface to be lowered and therefore dry the sub -base material. However, due to the inability to construct such a storm sewer due to the i„`a r-r.,4t _ l pro d"" of rpn�rnta lrr lt�citlVli bea 6Vi1 u'Giu. cayi+c, i]ao. r83 ._ .

The extent this concrete pavement would kk is from the approximate curb returns on the west end of the Whitcomh/River Meadows Drive intersection to the north to the approximate location of the transition from a 28' wide street to the existing, width of Whitcorib Street. we feel that due to the capabilities of concrete pavement to wi-thstand movement of the sub- base the section will endure longer than asphalt pavement.

Spring Creek must be improved to City standards prior to building permit issuance. All foundations in the flood plain must meet the City's Flood Hazard Area requirements (1'0" freeboard over 100 year flood level). 2. Existing flood plain must be shown on the plat. 3. The staff is concerned with the steep grade of Farmtree Road as it approaches Sheeley Drive. The maximum permitted grade is K. Please revise drawings to meet this standard. 4. The staff would recommend that Farmtree Road pavement width be reduce to 28 feet in order to save as much of the existing vegetation as possible. If there is any vegetation to be removed, the work will be done by the applicant. 5. The intersection of Farmtree Road and Rivermeadows Drive should be designed at 900 or less. The applicant will be responsible for signing of these intersections. 6. the applicant should provide evidence as to the ownership of the 50' of R.O.W. of Farmtree Road. 7, h1onumentation on plat is incomplete. Please correct. S. Legal description on plat should state "True Point of Beginning". Please correct. 5. The proposed plat does not agree with interior angles of existing sub- (iivision plat. Please correct. 10. Please be sure that all eagezents are correct and old ones no longer nerxssary are being vacated, Steve Van Lear 2 June 26, 1980 11. The width of some of the easements are not clearly indicated. 12. A portion of the rear lot line dimension for lot 29 is not shown. Please correct. 13. The portion of land between lots 33 and 34, and Tract A should be dedicated as public access easements and labeled on both the plat and site plan as such. 14. Tract A should be shown on the site plan as well as subdivision as open space area to meet the 30% P.U.D. requirement. The City's bike path and landscaping thereof should also be shown. 15. The staff questions the buildability of lots 23, 21, and 4. The applicant should provide evidence to justify their suitability. 16. The site plan should indicate location of fences if any; maximum height of structures; statement of planning objectives; development schedule; statement of future ov.nership of open space areas; number of bedrooms per unit; proposed coverage of structures; net residential density; 100 year floodplain; and existing significant vegetation. 17. Either building elevations must be submitted at this time or applicant must agree to Planning staff review of building elevations prior to building permit issuance. Before the staff can proceed with processing the application for development approval, a revised P.U.D. site plan, reflecting the above comments, will be required. For those items that cannot be shown on the site plan, a letter from the applicant resolving these issues should be submitted. The above materials should be delivered to this office no later than July 9, 1980. I would urge you to contact me before that deadline date to discuss these ccments or review your changes before you submit a formal revised plan. Also, on July 18 a rendered set of the site plan and architectural drawings and an 8" x 11" PMT positive of the plans must be submitted. If you have any questions, please feel free to call. Sincere Joe Frank, AICP S for Planner JF/19 The bike path being planned by the City will eventually connect with and be similar to the present one that goes from Taft Hill to Overland Trail through the Brown Farm area. It will also connect with the bike path going to the East part of the city. There are no plans at this time to extend South Whitcomb Street, but it could be a possibility for the future. It could connect with one of the Hill Pond streets. We will keep abreast of any plans. We had a great deal of discussion and spirited visiting, and reminded ourselves we have a neat neighborhood full of individualists. Ella Shawver described the early development of the area in 1954. She was the oldest (only in length of time in the Sheely area, not in years or spirit) resident- present for the meeting. The newest residents are Sally and Arlen Goodwine (at 1905 Sheely Dr.) and Mary Ontivares and Bill Burt (at 1901 Sheely Dr.). We were happy to welcome them to the area. Thanks to all of you who came to the meeting, and who contributed your knowledge of the area and ideas. We are glad the big white Birky farm house will he retained and enjoyed. There are two nice houses for sale in the area at 1913 Sheely Drive and 708 Birky Place. Both these families are anxious to move to their new homes, so if you know someone who has wanted to move to this area, be sure to contact me, and I'll do my best to keep good neighbors coming in as well as leaving us.

I believe we agreed to the following points: (1) The minimum requirement will be that the Developer provide for the passage of the flood designated by the F.L.A. study through his property in accordance with the City's floodplain ordinance. If the present channel is improved to confine this flood, such improvements shall be designed and installed at the sole expense of the Developer, subject to review and approval by the City. However, if additional. information developed prior to the construction of any channel im- provements indicates that flood flows in excess of the F.I.A. flood will pass through the subject property, the City may require the Developer to provide for these revised flood flows at his expense. (2) The Developer will provide a corridor within his development of suf- ficient width to allow for the construction of an improved channel capable of passing the flood flows developed in the Interi.am Flood hydrology Report for. Spring Creek. This corridor shall include the proposed channel recommended in the canal importation study. (3) The City will continue its present study of the canal importation project and the final analysis of Spring Creek in a timely manner; and (4) The Developer will agree to participate in the cost_ of improvements required in conjunction with the results of those studies to the extent determined by the City Council. If I have left anything out, or if you are in agreement with the points of our discussion as I have summarized them above, I would appreciate a written response to that effect at your earliest convenience. Please feel free to contact our office if you have any additional questions regarding your development. Sinoo—olY, Marc E:ngemoen Civil Engineer C I T Y O F F O R T C O L L I N S MEMORANDUM DATE: July 11, 1979 TO: John E. Arnold, City Manager FROM: Don Parsons, City Engineer' RE: Spring Creek Drainage In 1971, Black and Veatch prepared a drainage study for the City which has since become the foundation for subsequent drainage work. Black and Veatch proposed in that report three detention facilities on Spring Creek, one of which was located at Moore Park. Also included in the report was the assumption that the irrigation canals could be utilized in the transportation of storm runoff to Spring Creek. Preliminary investigations showed that it was cost effective to transport storm runoff through the canal from the west side of Fort Collins rather than through the developed older section of the City. In 1976, to follow up on the recommendations from the Black and Veatch Study, the City directed Land and Water Consultant, Inc. to perform a detailed design of the deten- tion facility at Rolland Moore Memorial Park. The report concluded that. such a detention facility was not cost effective based on the benefits. As in the Black and Veatch Report, it was assumed that canal importation of storm runoff t:o Spring Creek was feasible. Since the Moore Park Study demonstrated that the detention pond at that site was not economically feasible, it appeared advisable for the City to consider an alternative solution. In 1977, the City hired M.W. Bittinger and Associates to review all previous studies and make a recommendation re- garding what :improvements will be required on Spring Creek based on two assumptions. As in the past, it was assumed that importation of storm water into Spring Creek was feasible. From a curcory review of the canals, it was estimated that a 25 year storm could be imported into Spring Creek. It was also assumed that it would be more -2- favorable to project flows for future development based on the idea that in the future detention would not be required for new developments. However, this assumption was not consistent with the idea that if improvements to the Creek were not made and an individual received damages because of development upstream the City would have some liability. As a result, the City has continued to require detention in the Spring Creek Basin on an interim basis. After the completion of the Interim Report in 1978, the City selected Resource Consultants, Inc. to do a detailed analysis of the importation of storm water through the irrigation canals to Spring Creek. It was necessary to review this proposal in detail because of the substantial input it had on the overall master plan for the Spring Creek Basin. The preliminary draft of this report is presently being reviewed by the ditch companies involved and the Storm Drainage Board. The report shows that it would be economically justificable through detention and sorting of flows to transport storm runoff to Spring Creek through the improved canal system. Also, the report shows that the estimated flows from the canal system would be approx- imately 1700 cfs, a reduction from the 2200 cfs in the Interim Report.. A more detailed analysis of the hydrograph of the peak flows is in progress, which may result in an even greater reduction. Once the Canal Importation Study is complete, the next phase will be a final plan for Spring Creek based on the results of the Canal Importation Study. This spring, the Colorado Water Conservation Board was approached informally as to the possibility of sharing the funding of such a study. At this time, the CWCB has indicated they are virtually certain that funding would be available, but not until after the start of the fiscal year in July. To date, the City has not officially heard if the funding was approved. Once funding is approved, a comprehensive scope of work would be drafted and mailed to qualified consultants, taking approximately five months. Then the proposals would be reviewed, followed by a formal intor- view process, and contract negotiations are expected to take approximately four months. Because of the complexity of the Spring Creek Basin and the public hearing prOCGoo involved, the length of the actual project would be approximately eight or nine months, making the expect� completion time in approximately one and one-half ;g_ after the project has received funding. .'. There are two possibilities for obtaining inform Spring Creek runoff sooner: 1. Use all City funds rather than one-half one-half Colorado Water Conservation Bc -3- would require an additional $25,000 in City funds and would probably reduce the time by about three months. 2. Hire an engineer to prepare an interim -interim plan. This would cost about $3,000 and take about six to eight weeks, and result in a rough analysis of the effects of importation and detention in the Spring Creel: Basin. We anticipate that there would be some reduction in the peak runoff; however, it would still be necessary to complete the Spring Creel; design in cooperation with the Colorado Water Conservation Board. cc: Roy A.
