Box 580 Fort Collins, CO 80525 RE: #49-95E Harmony Ridge PUD Replat Dear Mr. Olt, (0 SOUTH FORT COLLINS SANITATION DISTRICT The Fort Collins - Loveland Water District and the South Fort Collins Sanitation District have reviewed the above mentioned project and submit the following comments. The water service to lots 9-12 needs to be abandoned at the main and relocated in accordance with District requirements. The sanitary sewer services that cross diagonally need to be abandoned at the main and relocated in accordance with District requirements. The design and maintenance of the access road over the sanitary sewer line needs to be submitted for review and comment. The District may require wider easements due the proposed location. Abandonment, liability and future responsibility of the existing sanitary sewer line needs to be addressed. The general notes need to be revised to indicate that water and sanitary sewer construct shall conform to the most current Fort Collins — Loveland Water District and South Fort Collins Sanitation District standards and requirements. The District requires easements on the District's standard easement form for all facilities that are not located within the public ROW. All disturbed facilities are to be re -tested in accordance with District standards and requirements. Are retaining walls proposed? The curb stop typical is to be deleted. The District requires meter pits for multi -family structures. 5150 Snead Drive, Foil.

April 18, 2002 Ms. Susan Joy City of Fort Collins Engineering Department 281 North College Avenue Fort Collins, Colorado 80522 RE: Harmony Ridge PUD, Replat Request for Variance - Driveways Susan, This letter is in regards to the Harmony Ridge P.U.D. Replat project, and in particular, to request a variance. Our clientfor this project is Overland Homes. The specific areas of concern are the driveways, and in particular to Section 9.4.2. Last year, the Department of Natural resources contacted our client regarding this project, which at the time is approved. They wanted to see if our client would break apart the approved 6 plex units into smaller 4-plex units, reducing the building mass as viewed from the Cathy Fromme prairie. Our client is working hard to accommodate this request, but this change has caused some new problems with the site layout, and in particular to the driveways. Section 9.4.2 states that In General, the entrance angle for all driveway approaches and intersections shall be as near 90' as possible. This site layout does accomplish this, in general, for a minimum distance of25'; from the street, There are some adverse angles of approach into the garage openings, farther than 25' from the street, in particular unit 70 and 71, but the owner has also provided additional driveway length which can be utilized as a turnaround_ We feel this is a better solution than by providing a more perpendicular access from another units driveway, in particular from lot 69 driveway. If the owner of Lot 69 would park a car in his driveway, neither of the owners of Lots 70 or 71 could access their lot. Therefore, because of the above mentioned design suggestions of City staff, we understand that we are required to request a variance to City standards. Therefore, on behalf of our client, we are requesting a variance from City standard 9.4.2. As this was ajoint decision between the developer and the City staff, we feel justified in requesting the variance. We do not feel that this variance will be detrimental to the public health, safety or welfare, nor will it reduce the design life of Dusty Sage Loop or cause the City of Fort Collins additional maintenance costs. Please call if you have any questions. ESincereJ1S Roger A urtiss, P.E.

The project in question is located south of Harmony Road, just west of Seneca, with the specific lots in question located on Prairie Ridge Drive, Dusty Sage Drive and Dusty Sage Loop within the development itself. All three streets are designated as Residential Local Streets. The three variance requests for this project are: 1. In accordance with Table 7-3, the minimum distance between a driveway and a street intersection is 80' from centerline to centerline. Lot 90 is 65' from CL to CL, Lot 108 is 57' and Lot 63 is 60'. Considering that both Prairie Ridge Drive, Dusty Sage Drive, and Dusty Sage Loop are all local streets with slower speeds and lower traffic volumes, we believe that allowing the driveways to be closer to the intersections will not adversely effect traffic, nor will it be a safety issue to the residents. 2. Table 7-3 also requires a minimum of 12' between driveway edges. Lots 67-72 are located on the end of a cul-de-sac with driveway separations varying from 3' to 10'. The narrowness of the lot frontages coupled with the cul-de-sac location does not allow for residential driveways to meet the separation requirements as called out in Table 7-3. We believe that granting a variance to the minimum separation requirements will not adversely effect public health or safety, or increase maintenance costs for the City of Fort Collins in any way. 3. Section 9.4.2 requires that driveway approaches shall be 90 degrees to the street, plus or minus 10 degrees. After reviewing the site and the low traffic volumes projected for the local streets, we agree with the Engineer's analysis. Any of the driveways that do not meet the standard are not significant enough to create a hazard for vehicles traveling on Dusty Sage Loop. I recommend approval for the above variance requests. Please let me know if you have any questions or concerns and if you need any additional clarification. Sincerely,, y Susan joy I Enclosures m EXIST. 8" SAN. SEW. XIST, SAN. SEWER SERV. EXIST. SAN.

They (the ditch) is now saying they want to sign off on the plans and since the original didn't have anything we need to get the necessaryu signatures. Otherwise they can stop the project as it relates to crossing their ditch. >>> Susan Joy 09/26/02 11:04AM >>> Dave... originally we told JR Engineering to make a note refering to the TST plans and that they didn't have to fully design this ditch crossing. But if the ditch company hasn't seen these plans and/or the old plans and they haven't signed off on anything to date, then technically we can ask for the full design, right? I mean, the ditch company will want it and they will definately sign off on this set of drawings so they'll have to show something more detailed. I just wanted to confirm this because you might hear complaints. >>> Dave Stringer 09/26/02 10:46AM >>> Susan, If neither Craig or Doug can Answer your question it needs to go back to Rich Devoract (TST) as to who from the ditch company did they deal with. Dave >>> Susan Joy 09/26/02 10:35AM >>> I may or may not have a problem that one of you can help me track down. I'm writing about the ditch crossing for the Cathy Fromme Prairie connection on this project. Originally the design called for a 12' wide bridge and a 12' wide maintenance path that was going to double as a pedestrian sidewalk into the prairie. The 12' requirement was made so that the ditch rider trucks and their occasional backhoe could get into the area for their yearly maintenance. Since the first filing, the replat has changed the location a little and the FCLW D will also need this path for their maintenance vehicles. Now for the interesting part. The original plan said that a bridge was required, but I was told verbally that since then, the developer (Padilla) had talked the ditch company into letting them pipe the ditch. But I can not find any documentation that says the ditch company agreed to this. Do you know of any? Or do you know who they spoke to at the Trilby Lateral? This is all coming up again because the last round of review on the Harmony Ridge Replat is now showing the ditch crossing for the first time and something just didn't look right. I called Gary Steadele (President of the Trilby Lateral Ditch Company) and asked him if he's seen this design at all or if he was the one who agreed to the culvert in lieu of the bridge. He said no to both questions and asked me who signed the plans from the ditch company agreeing to this. I told him that I would check and get back to him ASAP. After going through the plans and the project file, I can find no signature block that the ditch company has ever signed on the plans or any document with their signature on it agreeing to this. All we have that's officially signed off by the city is the site plan from Harmony Ridge PUD calling out the 12' bridge and the 12' maintenance road. The utility plans conflict this with a note calling out a 24" pipe and that the exact location must be coordinated with the ditch company. Again, the ditch company did not sign off on either one of these plans. So .... the question is - who said that the developer could pipe the ditch instead of constructing the bridge? And in case you haven't guessed by now, they want the bridge. Thanks very much for taking the time to read this. Any information you have would be very helpful! To: Steve Olt City of Fort Collins Current Planning 281 N. College Ave Fort Collins, Co 80522-0580 From: Gary Stadele Trilby Lateral President 828 Scenic Drive Fort Collins, Co 80526 Date: January 4,2003 Subject: Comments on #49-95E Harmony Ridge, Phase I- Replat of Lots 16-22 & Tract7 Steve Thank you for the opportunity to comment on the #49-95E Harmony Ridge, Phase I- Replat of Lots 16-22 & Tract 7. Directly to the East of this tiling is a area that the Trilby Lateral has had mud flow problems with. Below is a picture which shows the mud that was removed from the frilhy Lateral in May 2001. This is at the end of Praire Ridge. In the foreground you can see the silt fence that the mudflow knocked down before Ilowing into the 'Trilby Lateral ditch. On the backside you can see the 5-10 cubic vends of mud that was removed. The above mud flow was several hundred feed upstream of the replat area and is the justification for my comments which follow. A) A culvert in the Trilby Lateral would be almost impossible to clean out if another mud Ilow should occur. The Trilby Lateral requests that a bridge be built so that a clean out by backhoe and shovels is possible. A bridge similar to the one by Taft ff ill Road and the Cathy FYomme Trail has successfully been cleaned in the past and would be a good choice. 'I he bridge needs to be able to have a pickup truck loaded with 500 gallons of water cross it, thus at least a 10000 pound rating. This bridge provides the only maintancc access to the Trilby Lateral to the east of it. B) The silt fence directly adjacent to the Trilby Lateral has a silt trap on the up hill side. The silt trap needs to have a one foot deep spec on it. Also when cleaning occurs the silt trap as well as silt piled up on the fence needs to both be cleaned. C) Two additional standard silt fences on the hillside are requested. The purpose of these two additional fences is to limit the amount of silt that might reach the primary silt fence adjacent to the Trilby Lateral. D) The Dusty Sage Loop has a major street drain in it that if it becomes plugged will send all of the street water down to the Trilby Lateral. Street water flowing down the hill would result in a large amount of erosion. The Trilby Lateral requests that Frosion Control Fabric or rip rap or some other permanent erosion control measures be taken to guard against damage occurring from a plugged street drain. We also request that during the construction time no gravel filter tie placed in this street drain because that will limit the water flow to the drain and increase the likely hood of a street overflow.. To the West of this filing is the Harmony Ridge second filing. The Trilby Lateral worked with the developer on the Harmony Ridge Second Filing to come up with a design that would prevent mud from flowing into the Trilby Lateral from the development. Items B, C, and D are the same as those approved the Second Filing. 7pe. Yi v __j-Ll20 _ Ls \ I U2J bST rn.. ' 67 ` 019 !v ]68 �O N L118_ �.

I've attached a marked up portion of sheet 3 of 8 which shows my primary concern about moving the storm water pipe parallel to the Trilby Lateral irrigation ditch. Water from the Trilby Lateral will seep through 10 feet of soil to the storm water pipe. The storm water pipe will be on a layer of gravel which will act as a path for the water to follow. The water will flow to the point that the storm water pipe crosses the Trilby Lateral. Where the storm water pipe crosses the Trilby Lateral a very large elevation change occurs which will cause the water to flow fast and move soil with it. This could cause the Trilby Lateral to be undercut and eventually a complete washout could occur. It is very common along the Trilby Lateral to encounter very porous soils. There are sections that have a almost shale like soil. Thus I believe that it is very likely that significant leakage from the ditch to the storm water pipe will occur. This section of the ditch in wet years tends to have a spring water flow which indicates a porous soil that water can move through. A second concern is the construction phase of the storm water pipe. During this construction it is likely that soil and rocks will fall into the Trilby Lateral. If tile construction is clone when water is flowing this could cause the Trilby Lateral to become dammed and overflow it's banks. It is unknown at what point a overflow would occur. The "I rilby Lateral is a very flat ditch and the overflow could backup all the way to the Ridge where it could flow on to houses. The Trilby Lateral requests that you move the storm water pipe further away from the Trilby Lateral and to a higher elevation. The pipe should be moved enough so that the bottom of the trench that that the storm water pipe goes into be at a higher elevation than the lop of the Trilby Lateral. If this is done then no water flow from the'frilb_y Lateral to the storm water pipe is possible. No Text To: Leslie Jones From: Gary Stadele Trilby Lateral President 828 Scenic Drive Fort Collins, Co 80526 Date: March 17,2003 Subject: Comments on #49-95E Harmony Ridge, Phase I- Replat of Lots 16-22 & Tract7 On Saturday March 15, 2003 1 met with Leslie Jones at the Harmony Ridge Phase 1 Replat Site. Leslie had said that the Storm Water Pipe would be at a higher elevation than the Trilby Lateral Ditch. From just the drawings you cannot determine this since the elevation of the Trilby Lateral is not shown on the Storm Sewer Realignment Profile drawing sheet 5 of 8. This drawing does show that the storm water pipe would start at the existing ground surface. This surface is several feet above the Trilby Lateral. The drawing also shows that up to eight feet of fill would be added on top of the pipe. Sec the storm sewer realignment profile that I have redlined. After leaving the site and consulting with another Trilby Lateral board member it became clear to us that the existing Storm Sewer Realignment Profile drawings do show the storm water pipe mostly above the Trilby Lateral. This drawing is, however, in conflict with other drawings. The conflict is that the Storm Sewer Realignment Profile drawing shows up to 8 feet of fill being added at a distance that is only 10 ft away from the Trilby Lateral. Drawing sheet 6 of 8 shows that a silt fence and sediment trap be build in the 10 ft next to the Trilby Lateral. I've attached a redline of the silt fence and sediment trap that shows the profile that the Storm Sewer Realignment Profile drawing would require. These two profiles cannot both exist in the same space. The addition of up to 8 feet of fill in the 10 ft Trilby Lateral Easement would make travel along the ditch impossible. This would take away from the Trilby Lateral the ability to do maintenance along the ditch with equipment such as a backhoc. The design along the Trilby Lateral has conflicts from sheet to sheet that are too large to ignore. These must be resolved before acceptance. I ( i !

April 18, 2002 Ms. Susan Joy City of Fort Collins Engineering Department 281 North College Avenue Fort Collins, Colorado 80522 RE: Harmony Ridge PUD, Replat Request for Variance - Driveways Susan, This letter is in regards to the Harmony Ridge P.U.D. Replat project, and in particular, to request a variance. Our client for this project is Overland Homes. The specific areas of concern are the driveways, and in particular to Table 7.3. Last year, the Department of Natural resources contacted our client regarding this project, which at the time is approved. They wanted to see if our client would break apart the approved 6 plex units into smaller 4-plex units, reducing the building mass as viewed from the Cathy Fromme prairie. Our client is working hard to accommodate this request, but this change has caused some new problems with the site layout, and in particular to the driveways. 'Cable 7-3 states that the minimum distance between a driveway and street intersection should be a minimum of 80'. This table also states that there should be a minimum of 12' between driveway edges I would like to address each of these items separately. This replat is located towards the edge of the entire Harmony Ridge development. The Cathy Fromme Prairie is southwest of this site, ensuring that no additional development will occur adjacent to this site. Therefore, Dusty Sage Drive and Court will only experience traffic that is directly associated with these residents. In my opinion, traffic flow in this area will be very small. Allowing the driveways to be closer than 80' to an intersection would have no adverse effect on traffic, nor would it pose any safety concerns to the residents. Also, it will allow the developer to meet the density requirements for this site, as prescribed ny the current City criteria. The rational for the variance request for the second item, or the 12' separation guideline, should also be considered because of the low volume streets discussed above. In addition, the developer has worked hard on his site plan to combine driveways wherever possible to help minimize the total number of driveways that access onto Dusty Sage Loop and Court. 420 SOUTH HOWFS, SUITE 202 / FORT COLLINS, COLORADO 80521 / 970.221.4158 / FAX 970. 221.4159 . rr..., n � _ _ ^^°s^5+'m.:m^�';x'N+�^•'•�^gin
