It is my understanding that the hydrant elevations (with the exception of the one at Brpa-kwater and Skysai l) , are from changas in grade on your Lnol-,eer's part. Concerning the hydrant at Skysail and Dreakw=3ter, Bill Harding of Kelran Constructors and I discussed this elevation and decided that due to elevation changes by your F'ngineers it would be best to not raise this h,.drant until after the cu-b and cn-itter had b-en placed. Because of the low hydrants there is a definite fire hazard in your SLxiivision, and no more building permits can be released until such time as the situation has been corrected. If you have any questions, please :`eel free to contact me.

The Citv_ sees Landings Drive as having to handle "collector street" traffic for a considerable time before J.F.K. is dedicated and constructed. Therefore, we are asking that Landings Drive through "the Ridge" be designed to collector street standards to withstand this traffic load as well as to match the existing Landings Drive through the first filings of The Landings P.U.D.

Box 580 Fort Collins, Colorado 80522 Re: Lot 23, The Landings, Third Filing Fort Collins, Colorado Dear Mr. Smith: It is our understanding there is some concern regarding the effluent of the dewatering system at the above -referenced residence. The dewatering system is to intercept flows from the irrigation ditch at the rear of the property and divert these flows around the structure. These flows are directly related to irrigation, and in general, will flow only during the summer and fall months. It should be noted that the flow follows the bedrock formation to the lake north of the prop- erty. Prior to construction of the residence, free water was flowing in the cut section south of the roadway. This flow will continue to the street section in areas where the street grade is below the bedrock formation. The water diverted around the residence and directed to the flow line is an extremely small quantity and is generally continued to the concrete gutter and pan sections. This flow would, in our opinion, be no dif- ferent than irrigation water from the lawn reaching the gutter section or water that will continually flow in the cut section above the roadway. It would also be our opinion that since the water is generally confined to the gutter and pan sections that the water would not have a detri- mental affect on the asphaltic concrete street section. We would recom- mend, however, that the drain be constructed under the sidewalk and be installed with a permanent screen to prevent any type of obstruction.

It was felt that alternative #3 was a good start but should also consist of a rework of the intersection of Spinnaker Lane and Mariner Lane. The extra cost would make this alternative non -cost effective. It was felt, especially by Traffic, that alternative #1 was a signing of the condition that now exists and would not solve any problems but would create more. Rick did offer another solution. This solution would entail the removal of the "Keep Right" signs, addition of two "Stop" signs at the end of the 20-foot wide Spinnaker Lane and street striping across these intersections. The cost of this project would be approximately $200.00. He feels that this proposal should be done regardless of any decisions to do any other work and would like to know if you concur as soon possible. Jim is ready to prepare any additonal graphics that you might require. rl Tv nr V"w rC)I I IN IN ENGINEERING SERVICES October 7, 1983 TO WHOM IT MAY CONCERN: Re: Landings 3rd Planned Unit Development It is standard policy for the City of Fort Collins to accept for perpetual maintenance those public right-of-way constructions which have been approved by the City and which have passed all required guarantee periods.

In reviewing the subdivision agreement for Landings 3rd Filing dated May 24, 1978, all storm drainage improvements were to be completed prior to the release of 18 building permits and 9 certificates of occupancy. Currently there are more homes constructed in this area than what was stipulated in the development agreement. Yet the drainage system has not been completed. In addition, with the construction of the home on Lot 35 which is adjacent to Tract E, it appears this would be the best time to construct the pond and cause the least impact to the neighborhood. Please be advised that the City is now requiring the completion of the drainage system within the Landings 3rd Filing development. Until such time as these improvements have been completed or a proposed schedule for the completion of the required improvements has been submitted and approved by the Storm Drainage Department, no further building permits will be issued for this development. I regret the inconvenience this requirement may impose upon you, however, the number of homes presently constructed in the Landings 3rd Filing warrants the need for the completion of the drainage improvements.

May 27, 1977 Re: Installation of the Warren trunk line sewer Gentlemen: In In a meetin; hold on Nov 25, 1977, the Warren trunk line sewer scheduling, LOOS, repayment, and construction, u s discussed. Reid Rosenthal explained to the grouch the scheduling and cos': problems now associated with the Land - log: prom-ct which could he alleviated with installation of the trunk line lcwcr. The cost problems involve the construction of an entire second sewer Iinu on the west side of the Landings proiecL, Phase 1, and the construction A f a sewer main down IlorsetouL h Road. Purther, the grades required to in- :urc gravity !low to Lhe manholes at Stover and Ilorsetooth Road necessitates raising four cul-de-sacs in the Landi-i,gs, Phase 1, by three to six feet. Iris would necessitate 17,000 yards of compacted fill for the roadways and an additional 25,000 yards of fill to be placed around the basements of the homes on these cul-do-sacs. In addition, a lilt station would have to he i-nstalled to lift sewage from the eastern Lino to the wetern line for garvity flow to Ilorsctooth Road. By conservative estimates, the developer could save 1w104,000, or more, by simoly putting, in one eastern line running along the low points of Phase 1, crossing; tho inlet ditch to Warren Lake, and then extending eastward through Phase 11 to L(mavAvenuc where a tic -in could be made with the trunk line sewer. Besides saving; the developer money, the costly installation and maintenance of a lift station, and the problems associated therewith, could be eliminated for both the City and the developer. this simplified plan would allow all the homes in Phase I to flow eastward to the trunk line, thereby assisting; the City in its repayment plans for the trunk sewer line. The problems of coordinating the first occupancies in Phase I of the Land- ings with a tic -in to the trunk sewer line was also discussed. It was felt by the developer that the first occupancies would he in November, approxi- mately ::ix weeks ahead of the January I, 1978, minimum tie-in date proposed by the City. Roy Bingman, Tom haves and Reid Rosenthal agreed that in the event of occupancies preceding trunL line sewer tie-in, a properly sized and enyincered holding* tank could be installed to handle the few units that would have early occupancy. fhis tank would be located at the proper grade, and future maintenance for the few months involved would be the sole responsi- bility of the developer. 1912 Brockcwoud 03 484-8781) Tort Collins, Colorado 80521 conyruction - tKulopr—nt - rentals - solar desieu Page Two May 27, 1977 Reid Rosenthal explained to Bill Tiley and Bill Day, developers of the McMurrax farm to the east of the Land�i_pSs project, that his main concern wns grade point of the trunk tie-in and -not the exact location of the tic -in. The developers uptued Chat this would vivo T.lcy and Day the IatIitudec to proper Iy design green spree and street locations of their project, without boring hampered by particular casement locations. In discussions with Rug Bingman, Tom 1layes and Lloyd McLaughlin, the developers explained their wish to proceed quickly with the sewer line cxtcnsion. It was generally Pelt that because of rising costs, poss.i.- hle delays in development and construction time, and the low water level of this particular summer, the Projects should proceed as rapidly as possible. Roy and Tom explained that their departments were snowed under at this time and could not possibly proceed with design and construction of the trunk line sewer with any hopes of maintaining a tight schedule. The developers agreed that after consulting with the other two landowners involved, tiny would be willing to proceed with the hiring of a consul- tant who would design the trunk line sewer and perhaps go as far as putting the project, to bid by privai^ companies. It was made clear, however, by the developers, that before work could proceed a repayment schedule from the City to the developers for work done must be agreed upon. It was further stated that work should commence only after art March drew agreements providing for the repayment by the developers to the City for the costs of the trunk line sewer as hookups were made. Tiicy and Day explained that design, casement requirements, and bidding could he accomplished in most cases simultaneously, to speed up the installati_o°i of the line. In the meantime, City Officials could proceed with the approvals and annexations necessary to installation. It was agreed that the developers would call a meeting of the four land- owner_; involved to establish a specified procedure for getting the neces- sary wait done. Preliminary *proposals and, perhaps, draftings would be submitted fo the City by Alonday, junu G, 1977, in Kine for the scheduled June 9, 1977, meeting, between developers, engineers and the water depart- ment concerning the next steps to be taken on the trunk line sewer. e 7, Sirlerei� Reid L.

As you recall, this project has final city council approval contingent upon your approval of the utility plans. In addi- tion, you had allowed us to make our initial submittal with sewer line layout only. This was to allow no time to firm up an elevation which will allow flow to the Warren Lake Trunk Sewer. During the past few weeks we have had confirming con- versations with John Effinger and Chuck Liquin assuring us that we can design our line for a minimum slope condition and be confident gravity service is possible. In that light we have designed our entire main outfall line, using 10 inch diameter pipe at a slope of 0.28 percent with 0.1 ft. or 0.2 drops only where we have sharp bends or more than a single line into the manhole. This will minimize any impact upon the depth of the trunk sewer line. Therefore, we have proceeded to show both plan and profile design of the sanitary sewer on this particular set of plans.

I observed that neither the outflow on the west side of Mariner or the inflow at the cross pan on Mariner Drive were working properly. The storm waters were being detained in the street rather than to the ponds. On May 10, 1_979 I again inspected the streets throughout this subdivision and noted nuaierous areas of subgrade failure due to the inadequate drainage of the detention systems. For this reason the City cannot accept the streets in The landings subdivision for maintenance until all areas of street failure have been repaired.

August 24, 1977 CcntItmen: In a mooting he]d August. :22, 1.977, "1 the Water I Sewer ➢eniriwant , the ccst of the Warren Lake trunk line sewer due to construction diffi(nItics was discussed. It was pointed out by Phi_I Robinson or Stewart if Associates that their preliminary estimates, while not actually bids, pointed CO the trunk line costing a total OF $990,000 +, a figtrc in excess of initial projections. Part of this increased cost was attributed to the increased depth of the sewer across the southern portion of the Landings project and on Lcmay north of Warren Lake. Roger Krempel and Reid Rosenthal discussed the fact that this increase in depth on Lcmay was due primarily to the depth of the sewer necessary io serve the northwestern portion of the Landings on Ho'rsetooth Road. t y further agreed that it would be unfair, despite the agreement alruNdy in effect, to assess the other developers involved with the trunk the extra expense of that added depth. John Effinger pointed out that it was possible to considerably raise the sewer through the southern part of the Landings and still provide for a proper depth crossing of College Avenue. This raising would be facilitated by a drop manhole at the sewer outfall point on Lemay Avenue. The group agreed that an average of three feet in depth could be saved through the IS00' length of the southern Landings sewer. Ilo,.ace Muyurs then brought up the suggestion that a lift sintion Uc installed near the Warren Lake inlet crossing separating Landings, Phase I, and Landings, Phase H . The group concurred that this would solve several basic problems for the City, the Landings, and the other developers. First, the 700' of trunk sewer on Landings could be lifted an average of 1.5' with increased .savings in cost and time. Secondly, the problem of assessing extra costs to any developer or group of developers for the increased depth of the trunk would be alleviated. Third, the installation of the lift station would save. the Landings considerable depth throughout portions of its internal system, and the cost savings reflected there would out -weigh the extra initial cost of the lift station itself. Roger Krempel made it clear that the lift station must have an auxiliary power source in the event of a 1912 Brookwood 303 1044789 Fort Collins, Colorado 80521 construction - development - rentals - solar design CORNER CONSULTINC, COMPANY po Ix)x 646 1010 (01[ s, (NoRvO 80V)2 ph( vv (303) 482-6(Tk - " MANA(iLMEN I/ENGINFFRIN(j August 24, 1977 Mr. Lloyd McLaughlin City of Fort Collins 300 LaPorte Ave. Fort Collins, CO 80521 RE: Landings - Phase I, Filing 1 Utility Plans Dear Mr. McLaughlin: This is in response to our telephone conversation earlier today regarding changes which were made in the utility plans follow- ing your earlier review. The original drawings were submitted to you August 19, 1977 as per letter dated August 17, 1977. The following are the basic changes made, other than those requested by your earlier review. 1. Valves were shown on the 6 inch water line loop into Spindrift Court, where they were thought to have been overlooked. We now understand that these valves are not desired, therefore they will be deleted as per our conversation. 2. The 20 inch valve east of the 20"xl2"tee at Landings Drive was deleted. This was based on the fact that water service to the Landings project will be looped back to Horsetooth Road and ultimately to Harmony Road and College. The Horsetooth Road tie being anticipated in a comparable time frame with the tie at College Ave. and Horsetooth Road. 3. In coorinating our project with other projects on the north side of Horsetooth Road, we determined the Page 2 50"x3l" arch culvert, which was previously designed as part of the Strachan Project, was much larger than currently allowed for storm detention release. Therefore, the arch culvert was deleted. In lieu of this, the existing 15 inch CMP is being extended rather than plugged, and the 12 inch pipe extending across the intersection is being added to complete their detention discharge arrangement. This culvert is being shown based on preliminary information provided by James H. Stewart and Associates relative to their work on the adjoining project. 4. The street width on Landings Drive has been changed from 54 feet to 44 feet in accordance with earlier discussions with the city staff. 5. The following changes have been made on a sheet by sheet basis: Sheet 2 - Revised the typical fire hydrant detail for clarification of valving. - Added storm drain crossing. - Manhole 12-A will be removed and relocated to proposed location under filing No. 2 Utility Plans. Sheet 3 - Added sidewalk detail on Spindrift Court, to show transition. Sheet 4 - Note for clarification in locating sidewalk transition. Sheet 5 - Added storm drain crossing. - Manhole 12-A will be removed and re- located to proposed location under filing No. 2 Utility Plans. Sheet 6 - Adjusted flowline curb profiles between Station 9 + 75 to 11 + 03.8 to allow for change in street width. Sheet 8 - Detention Pond "B" will use cross pan gutter in lieu of storm drains and inlet arrangement shown - (See sheet 6 detail).

September 14, 1977 Robert G. Butler, vice pros. Gentlemen: At a meeting held September 13, 1977, to discuss the installation of a 20-luch water line along Horsetooth Road to service the Landings, it was decided that a list of contractors would be supplied by Lloyd McLaughlin, and that this list would be the one used for bidding said project. It was explained to the group by Reid Rosenthal that time was of the essence. Bid documents would be prepared by Harry Cornell as quickly as possible, with work hopefully commencing within two weeks of the meeting date. Fast completion of the project is necessi- tated by the need for fire protection for structures in their framing process. Rosenthal's other option is to install a rather costly temporary pump station in the lake with a line extending to the con- struction. site. It was agreed that because time is such a critical factor it this project, that the lowest bid would not necessarily be the one accepted, although any bids accepted by Reid Rosenthal would be approved by the City using a comparison of the installation of 20-inch line on Drake Road by Rex Miller earlier this year. It was decided that the bid documents would be mailed with Return Receipt Requested and that the contractor would have one week to bid the project. The availability of pipe was discussed and Chuck Liquin suggested that Reid order the materials necessary for the project and assign them to the contractor awarded the bid in order to save a week or more of delivery time. Either 50 or 52 ductile iron would be accepted by the City. harry Cornell commented that Horsetooth Road would be slightly shifted to save the trees along the North edge of the Landings project and this might necessitate a light shift in the water line. In addition, there are S utility lines now running along the south side of Horsetooth Road including two gas, two telephone, and one Davis County Water line. Harry Cornell suggested that these utility lines might also necessitate a slight shift in the installation, and this was agreed to by all parties. Ed Hilgcnberg concurred with Reid in the ordering of necessary valves from the Denver water board, or other available sources in order to meet the construction schedule. 1912 Brookwood 303 484-8789 Fort Collins, Colorado 80521 construction - development - rentals - solar design Y Of FORI COO INS _ _. . _P,O,_BOy `WATER AND SEWER LITILII IES Too 580„f0RT.Ii;;LLlNS,.COLOB ADO . 80522 - PH 1303) 489-4220. MEMORANDUM TO Paul A. Lanspery, Interim City Manager FROM: Roger E. Krempel, P.E., Water Utilities Director F(". ;.. RE Proposed Private Sewage Lift Station for Landings Development DATE: September 15, 1977 As progress has been made in preparation of the Warren Lake Trunk Sewer Line by James Stewart Consulting Engineers for developers proposing to utilize the sewer, the cost estimates for the project are becoming more accurate based on better information. Getting onto crop land has prevented final plans and final cost estimates. Nevertheless, Reid Rosenthal representing Landings Limited, who will hear, the largest cost in the trunk line, desires not to lay the last or most westerly stretch of sewer 22 to 26 feet deep to provide a gravity sanitary sewer solely for his Landings Development and wishes to lay a shallower sewer and lift the sewage with pumps. The Sewer Utility has steadfastly refused to accept a sewage lift station in the City system when a gravity sewer can be made available. Rosenthal has proposed that the lift station be approved with conditions that the City is to be totally free from any cost or responsibility for a lift station in his development. An agreement setting forth such conditions has been drafted and the Utility staff approves of the agreement subject to legal and Council approval. Rosenthal's reasoning for proposing the lift station are outlined in his letter dated September 14, 1977. REK/sl it I i CITY P�1RfJAGR 100% Recycled Bond c» my home Reid L. Rosenthal, pres. September 14, 1977 Robert G. Butler, vice pres. Mr. Roy Bingmnn Mr. Roger Kcemple Engineering Department 300 Laporte Avenue Fort Collins. Colorado 80521 Gentlemen: This letter is to discuss with you our agreed upon installation of a lift station tc be located in the Third Filing of Landings and to be maintained at no City expense for the duration of its existence. Though lift stations have for the most part been frowned upon by the City of Port Collins, the topography of this particular piece of development ground makes the installation of the lift station man- datory for cost-effective development of both Landings, and of the Warren Basin trunk sewer line. Basically, -here is no other piece of land in the Fort Collins area. with the topographical characteristics of the piece of ground sur- rounding Warren Lake. Without the lift station, sewer depths could reach 22-26 feet, thereby creating extra cost for both the City, the other developers involved in the trunk line, and Landings, itself. In addition, there could be possible problems with underground water siphoning from such a deep line from Warren Lake Reservoir. With the installation of the lift station, with no cost to be born by either the City or the other developers involved in the trunk Line Project, a great amount of this depth can be alleviated both in Landings and in that portion of trunkline in Lcmay. Also, possible water siphoning from Warren Lake would be eliminated. Maintenance of this lift station will be completely without City part-icipation, with the initial cost to be born by the developer and eventually by the home- owners association. The homeowners association involved in the Landings will be a large and financially affluent organization. Cross income to the organization should comnrisc approximately $180,000 per annum at the project's completion. liven after maintenance of green areas a very sizeable sun of money will remain in the organization's treasury. The cost of running the lift station on a monthly basis can be as low as .$150 per month according to my engineers. 1912 Brookwood 301 44 -8789 Fort Collins, Colorado 80521 0 4'1 i a.

A site inspection indicates that the following public right of way improvements have not been completed: 1) Vertical curb and gutter installed along Horsetooth Road 2) Seven (7') foot meandering concrete sidewalk installed along Horsetooth Road 3) Road base and navement installed on Horsetooth Road 4) Manholes and valve boxes raised to finished grade on Spin Drift and Iorsetooth Road 5) Seven (71) foot concrete walk installed from Horsetooth Road to Spin Drift 6) Street cleaned of dirt and construction materials In addition these are many items still incomplete in other areas of the Landings 1st which you have been made previously aware of but have not yet taken any action on. These include: 1) Suhnittal of an as -constructed set of engineering drawings showing changes in the public right of way constructions in the intersection of Horsetooth Road and Landings Drive, particularly the water main which is directly beneath the curb and gutter. This water main configuration has not been approved by the City and may not be. 2) Tnstall a four (4') foot sidewalk along the east side of Landings Drive as shown on approved utility plans. 3) Complete detention ponds on Mariner Lane to conform with approved utility plans. 4) Grade drainage swales from cul-de-sacs so that water will flow from these streets into the detention ponds. 5) SuYmit written verification to the City Engineer from your development engineer that the detention systems (ponds and swales) are constructed according to approved utility drawings and are to correct grades and capacity. 6) Repair the streets in the subdivision which have deteriorated due to ponding water as a result of the detention system not being properly graded. 7) Raise manholes to finished grade in the intersection of Horsetooth Road and Landings Drive. 8) Place rip -rap at the outlet of the drainage pipes at Horsetooth and Landings. 9) Place traffic delineators along the south side of Horsetooth Road on the west side of Iandings Drive to prevent traffic from going into drainage swale. 10) Clean pipe inlet at southwest corner of landings Drive and Horsetooth Road to allow complete drainage. Page Two Any possible malfunction of equipment could easily be born by the home- owners association. Most importantly, all members of the Association are tied legally to the support of the lift station. This has been accom- plished through the use of deeds for every piece of ground out there which are specifically encumbered by the covenants which will be of record with the Larimer County Courthouse. These covenants, besides spelling out a strict set of esthetic requirements and organizational procedures, refer specifically to the maintenance of certain facilities, namely the lift station, by the homeowners association for perpetuity. Sets of covenants are given with the sale of every lot and h,.e and also references( in the contract for that piece of ground and structure. To make the system as fail-safe as possible, provisions have even been made for an alternate energy source in case of blackout; namely a generator unit. The system, in addition to its vast practical, construction, and economic advantages to both the developers and to the City will serve one more important function. It will have a decided economical effect on the consumer. In this developer's professional opinion, the additional cost of a lot in certain sections of Landings without the system could be increased as much as $5,000 per lot. Amortized at 90 on a 30-year basis, means that the eventual cost of not putting in a lift station to consumers could comprise close to $14,000 over a 30-year period. It is my feeling that most consumers would rather not be involved in a front end expense such as this and in addition would rather amortize their expenses at a rate of ONUS per month for the duration of their stay in their residence. Fm cially, if homeowners fees were also being applied to recreational facilities and large park areas. As a matter of fact, the cost to an individual homeowner in Landings, assuming 1400 units upon completion of the proiect and a $200 per month operating cost for the lift station, equates to 14.3t per month for the operation of this lift station. A small price to pay to live in such an environmentally perfect location. I appreciate your consideration in this matter and the concerns you have expressed over the maintenance and economic factors of the installation. I feel you have made an excellent decision in ,your approval of the instal- lation and I thank you for your time as do the other developers involved in the trunk line. in I C;p \_j6)n0-CccCc4(i,C IReid L.

Lanspery, Interim City Manager i FROM: Roy A. 6ingman, Engineering Services Director RE: Seviage Lift Station in the Landings Subdivision' I became aware recently that a sewerage lift station is being proposed for the Landings Subdivision. The lift station has been proposed by the subdivider on 'he basis that it is a less costly alternative than it would be to provide gravity sewage service through a trunk line extension. It has been estimated that the cost of installing the sewer trunk line at sufficient depth to serve this subdivision would be an extra $200,000. The developer is saying that the cost to the homeowners would be less in the long run by using a sewage lift station than it would be by expending the $2.00,000 to se^ve this area through a gravity sewer. From the standpoint of the sewer utility, the operation of a lift station is expensive and, generally speaking, a maintenance problem. On this basis, the Water and Sewer Department has said that they do not wish to accept the sewage lift station as a maintenance item by the City. The developer then proposed that -.he Homeowners Association would provide for the maintenance and cost of operation of the sewage lift station without any City involvement. I feel that this proposal raises several points which should be addressed by the City Council: (1) Even though there will be a stipulation in the deed for each individual piece of property in the subdivision to cover the homeowners fee, which will include the cost of operation and maintenance of the lift station, it seems to me that the average buyer will not be fu lly aviare of the obligation or the problems it might pose to the Homeowners Association in the future. (2) Even though the Homeowners Association and the property oviners are legally bound for the maintenance and operation of the lift station, there is the possibility that in five or ten years, the Association might question whether the City should have required the Homeowners Association to be responsible for the operation of this lift station. It appears to me that a future City Council could feel that this was an unnecessarily large burden placed upon the Homeowners Association. J Page 2 Lift Station in the Landings 15 September 1977 (3) This might set a precedent for other subdividers to avoid the costs for sewer trunk extensions through the use of lift stations. (4) There is no guarantee that the cost -savings resulting from the installation of the lift station will, in fact, be passed on to the purchasers of property in the subdivision. (5) The cost of operation and maintenance for the lift station will increase in the future. Although this expense may be nominal in the early years of operation, the cost could be substantial if it is necessary to overhaul or replace expensive pumps and motors or standby equipment. l-,ci,l I..

Due to realignment of L01ay Avenue at the connection with Breakwater Dr. at the east entrace to Landings Filing 3, our proposed manhole tie is approximately 100 ft. from a manhole tie as proposed by the Warren Lake Trunk Sewer design. Since we only have 0.5 ft. of drop built into the approximate 3,000 lineal feet of ten (10) inch line through Filing 3, we can ill afford to use up approximately 0.3 ft. of this to make the 100 ft. connection. Thus you agreed to coordinate a change in the elevation of the proposed manhole elevation for the Trunk Sewer from 4974.40 to an elevation of 4974.10 , thus not imposing undue constraints on our design. /t Reid Rosenthal Page Two The City has been very cooperative and has released certificates of occupancy within The Landings 1st since May of 1978 even though many of the required public irprovements for the area were not completed.

It has recently come to our attention that the trench width being excavated on the captioned project is greater than the plans or the City specifications permit. Cornell Consulting Company takes the following position in this regard: 1. The pipe should be installed according to the approved plans. 2. Failure to conform to the specified trench width, according to our calculations, will result in pipe deflections exceeding 2%. 3. Enforcement of the contractor's adherance to the plans and specifications is not within the scope of Cornell's responsibilities at this time. It is further our opinion that neither Cornell nor the owner should be liable for consequences of construction not performed according to the approved plans. Please give me a call if you have any questions or would like any further information. Very truly yours, Yry rnell, P.E.

Curb $ gutter, sidewalk, and paving on Horsetooth Road. I believe you have a letter from Sterling Paving saying that they have been contracted for the work, and it will be done as per the utility agreement no later than October of 1979. I have talked to the City Attorney and Roy Bingman and it is their opinion that C/0's may not he held up due to improvements listed in ,your letter. I will therefore expect clearance for all C/0 and building permit requests as soon as possible. 2. Harry Cornell is in the process of submitting an "as constructed" set of engineering drawings for the intersection of Horsetooth Road and Landings Drive. I would expect this to be in your office within the next 5 to 10 days. 3. Install a 4 foot sidewalk on east side of Landings Drive. We have submitted an application to Council to delete this sidewalk, and to place it, instead on the west side of Landings Drive at the time �Iandings Drive is constructed to the John F. Kennedy Parkway. 4 Cornell is in the process of submitting the written verification you requested that our detention systems are constructed according to the utility drawings and are to correct grade and capacity. The detention systems themselves, including concrete wash basins, Mr. Bob Zackley May 30, 1979 Page 2 the downstream side of the underdrains, the drain structure for the larger detention pond below the tennis court, will be finished within the next 10 days, weather permitting.

Box S80 Fort Collins, Colorado 80522 Re: Landings Filing 1 Detention System Dear Mr. Stringer: Mr. Reid Rosenthal has asked our office to respond to your letter addressed to him dated May 10, 1979. On May 25, 1979 a visual inspection was made at which time a memo was submitted to Mr. Rosenthal stating those items which should be completed in order to comply with plans as approved. A copy of that memo is enclosed for your information. On May 30, 1979 a second inspection was made during a rain storm to see if there might be other concerns. From that, I have con- cluded that by following our recommendations the system will function properly. In regard to your comment about subgrade failure -- there has been some: failure most particularly along the west edge of pave- ment on Mariner and immediately adjacent to the crosspan gutter on Mariner. In my opinion, the failure immediately adjacent to the crosspan is the only one that has any relation to the detention system problems. Along the west edge of Mariner from Landings Drive to Spinnaker Lane, the gutter is functioning properly and I can only conclude that these failures are more closely associated with another cause such as consolidation of subgrade prior to placing the pavement section (a yielding subgrade). These low. spots do tend to follow the water main alignment in Mariner which may be another consideration. Please give me a call if you should have any further questions.
