Yours Truly, *)e Steve Olt, City Planner cc: Marc Virata Stan Everitt The Birdsall Group Northern Engineering City Current Planning File #37-04B Page 12 Detail how the pipe outlet from pond 305 will be tied to the existing inlet box. Topic: Water Quality Number: 95 Created: 7/29/2005 [7/29/05] Please provide water quality calculations as well as an outlet box design for ponds 304 and 305. The following comments and concerns were expressed at staff review on July 27, 2005: Engineering: 1. What is the outcome on the perimeter drain system? 2. The South Lemay Avenue design is lacking. 3. Please verify with the utility companies their position on the features in the easements. 4. Staff needs a letter of acknowledge from the property owner to the south about the driveway. 5. Need more information on the street drain system. Transportation Planning: 1. There are bicycle issues associated with Lemay Avenue. Stormwater: 1. Most of the floodplain comments have not yet been addressed. Please contact Marsha Hilmes-Robinson about these concerns. ********************************************************************** Page 11 10. A floodplain use permit and $25 fee are required for the stormwater outfall into Stanton Creek. Please include a detail of how disturbance to the channel bed and banks will be minimized. 11. Please see checklists for items relating to floodplains that must be included in the drainage report. Topic: Eroding Plans Number: 90 Created: 7/29/2005 [7/29/05] Please call out minimum top of foundation elevations on the grading plans. There are several rear lot swales designed, please add notes to the grading plan as well as the plat that prohibit the construction of fences or other vegetation that may inhibit the flow of drainage from one lot across the downstream lot. A pan may be needed in this situation in order to set the grade. Topic: Plat Number: 94 Created: 7/29/2005 [7/29/05] Please show Tract G to be owned by the Developer (HOA) on the plat. The dedication should be done to the City by separate document after platting in order for the City to be able to keep track of all the property it owns and maintains. Topic: Pond outlets Number: 93 Created: 7/29/2005 [7/29/05] The detention pond outlets into Stanton Creek look they are set at an elevation that will cause erosion to occur downstream of the riprap pad. Please extend outlet to bottom of slope. Make sure the riprap in the Natural Area is buried. Call out re -vegetation for the disturbed area, show disturbance limits and construction fences around the pipe outlets. Topic: Utility Plans Number: 96 Created- 7/29/2005 [7/29/05] The outlet from Pond 305 might conflict with existing utilities or landscaping. The utility plans do not show, if there are any existing utilities in that area, please make sure that proposed pipe will not interfere with existing features. Page 10 4. The erosion buffer zone and floodway must be staked in the field and marked as a no disturbance area except for permitted items in the buffer and floodplain (i.e. stormwater outfall). Include as a note on the plans and in the drainage report. - REPEAT COMMENT 5. A floodplain use permit and $25 fee are required for the stormwater outfall into Stanton Creek. Please include a detail of how disturbance to the channel bed and banks will be minimized. - REPEAT COMMENT 6. Sheet 8, Overall Landscape Plan - Please include a note that "No irrigated vegetation is allowed within the erosion buffer zone. Any plantings within the erosion buffer zone or floodway require a floodplain use permit." [11/9/04] Floodplain Comments 1. Please see the included floodplain checklists for items required for 50% and 100% submittals. 2. The plat must show the floodplain/floodway boundary. The floodplain and floodway boundaries are the same along Stanton Creek. 3. Please show the floodplain cross -sections and BFE's on the drainage and grading plans. 4. The erosion buffer zone needs to be shown on the site plan, drainage plan and grading plans. The erosion buffer zone is different than the natural resources buffer. 5. All development must be outside of the erosion buffer zone (except the required stormwater outfall). Please review plans for development that is currently shown within the erosion buffer zone. In particular, look at lots 12115, 16 and the detention pond. 6. Please see checklists for other restrictions on buffer zones including no construction traffic, storage of materials, fill, irrigated vegetation, etc. Please include notes on the plans about these items 7. The stormwater outfall must be constructed so as to minimize disturbance to the channel bed and banks and also no fill is allowed in the floodway. 8. Any construction in the floodplain/floodway outside of the erosion buffer zone must be shown by a hydraulic analysis to cause no -rise. To avoid hydraulic modeling, all development must stay out of the f loodplai n/f loodway. 9. The erosion buffer zone and floodway must be staked`in the field and marked as a no disturbance area except for permitted items in the buffer and floodplain (i.e. stormwater outfall). Page 9 Topic: Soils Report Number: 14 Created: 11/5/2004 [7/26/05] The original soils report was submitted with the final plan. Per the original comment, the potential need for a street drain system needs to be addressed. [2/15/05] The response letter indicates this is to be addressed at the time of final engineering. This is sufficient, comment is carried over for reference. [11/5/04] The soils report will need to address whether street drain systems are recommended as was done in the Stanton Creek subdivision directly north. The general area has high swelling soils and fly ash was used with the recent work on Lemay Avenue. Department: Natural Resources Topic: 6enerol Number: 98 [8/2/05] No remaining issues. Department: Stormwater Utility Topic: Floodplain Issues Issue Contact: Doug Moore Created:8/2/2005 Issue Contact: Basil Hamdan Number: 55 Created: 11/9/2004 [7/29/05] All previous comments have not been addressed. Please address these with the next submittal. [2/16/051 Lemay Avenue Estates Floodplain Comments 2-8-05 1. Please show the floodplain cross -sections and BFE's on the drainage and grading plans. - REPEAT COMMENT 2. Please see checklists for other restrictions on buffer zones including no construction traffic, storage of materials, fill, irrigated vegetation, etc. Please include notes on the plans and the drainage report about these items - REPEAT COMMENT 3. The stormwater outfall must be constructed so as to minimize disturbance to the channel bed and banks and also no fill is allowed in the floodway. Please provide a detail. - REPEAT COMMENT Page 8 Number: 97 Created: 7/29/2005 [7/29/05] Please provide additional spot elevations at the t-intersections as redlined in the plans for verification of street design. The intersection design details in general look good. Topic: General Number: 18 Created: 11/5/2004 [7/26/05] Carried over as reference. [2/15/05] The response indicated that a letter of acknowledgement of the driveway reconfiguration from the property owner will occur once agreement is made on the plan set (approval?) The letter of acknowledgement will be required prior to any City approval on the engineering plans. [11/5/04] In general, it appears that there is sufficient right-of-way south of the site in order to allow for the work along Lemay Avenue. However, we'll need to get evidence from the property owners south of here that they are aware of their driveway configurations being changed by the project. (The construction plans need to show the newly configured driveways with the road improvements and grading to demonstrate that off -site easements are not necessary. Number: 20 Created: 11/5/2004 [7/26/05] Carried over for reference. (2/15/05] Carried over for reference, as it appears the utilities have not been contacted thus far. It is suggested that this issue be verified earlier than prior to construction as it may result (worse case scenario) in having to modify plans that were previously approved. [11/5/04] The utility companies will all need to allow the fencing, columns, and planters which are proposed within the utility easement along Lemay Avenue. Number: 83 Created: 7/26/2005 [7/26/05] The sidewalk along Mountain Home Drive within Tracts A & 8 needs to be in access easement where it falls outside of right-of-way as specified on the site plan. The access easement will also need to be described in a manner in which the access easement is only for a height of 10' where it lies within the arbors. Page 7 - 12.5' travel lane - 12.5' travel lane - 8' bike lane - 19' parkway - 6' sidewalk Total = 57.5' (half ROW) Number: 85 Created: 7/26/2005 [7/26/05] On Lemay Avenue, the northbound bikelane that currently starts north of Mountain Home Drive shall be striped down to the southern boundary of the site along the curb and gutter. Number: 86 Created: 7/26/2005 [7/26/05] On Lemay Avenue per my conversation with the City Traffic Engineer, the 30:1 tapers shown should be changed to 40:1 tapers. Number: 87 Created: 7/26/2005 [7/26/05] The southbound Lemay design merge should "reverse", the right lane should merge into the left lane. Number: 88 Created: 7/26/2005 [7/26/05] In general the Lemay Avenue design is lacking in vertical information (however the onsite design appears good and complete). 1000' of offsite design per LCUASS standards is also required. Number: 89 Created: 7/29/2005 [7/29/05] Ensure that intersection information is updated on Mountain Home Drive and Lemay Avenue. Number: 91 Created: 7/29/2005 [7/29/05] Please provide detail information on the cul-de-sacs (spot elevations, flow arrows, high points, grades, etc.) per LCUASS detail 7-19. Number: 92 Created: 7/29/2005 [7/29/05] Please provide detail information at the two street turn intersections (Honholtz & Showline), (Showline & Woods Landing) in order to verify how cross slopes and drainage works. Page 6 Number: 22 Created: 11/5/2004 [7/26/05] What was the outcome regarding this? Will a perimeter drain system be used and if so how will the systems outfall, or will a subdrain system be designed? If a subdrain system is proposed, the plans need to reflect the design. [2/15/05] The response indicated that the necessity of a subdrain system is to be addressed at final engineering. This is of concern, as if a subdrain system is to be proposed, without a preliminary design at this time, it cannot be verified that a suitable outfall for the subdrain can be designed without perhaps needing to daylight onto property outside of this development (when a letter if intent would be required prior to going to a hearing) or needing to redesign the site after the hearing. The question of a subdrain system needs to be resolved prior to a hearing. [11/5/04] The soils report mentions a perimeter drain system, will an actual subdrain system be proposed by the development? A groundwater report may be required. Number: 84 Created: 7/26/2005 [7/26/05] Per previous discussions after hearing, the following horizontal alignment is required for the northbound Lemay Avenue right-of-way adjacent to the site: At the Mountain Home Drive intersection from the centerline of the street (where a left turn lane exists): - .5' of additional median to the 6' median on the other side of the street for a total median width of 6.5'. - 12' turn lane - 12' travel lane - 12' travel lane - 6' bike lane - 9' parkway - 6' sidewalk Total = 57.5' (half ROW) Past the intersection from the centerline of the street (where no left turn lane exists, median only): - 9.5' of additional median to the 6' median on the other side of the street for a total median width of 15.5' Page 5 Number: 101 Created: 8/3/2005 [8/3/05] Terry Farrill of the Fort Collins -Loveland Water District and the South Fort Collins Sanitation District offered the following comments: a. The District requires minimum 30' wide easements on the District's standard easement form for all facilities that are not located in the public right-of-way. b. The sanitary sewer connection to the existing manhole is to be core drilled. c. The interior meter setting typical that is labeled standard manhole detail on Sheet 01 of the utility plans is to be deleted. The District requires curb stops for residential development. There are no irrigation taps identified on the project. The meter pit typical is to be deleted. The sewer joint encasement detail is to be identified as storm sewer encasement. The District does not allow encasement of the sanitary sewer line. d. The District does not allow landscaping or trees within 15' of a sanitary sewer line. Please contact Terry, at 226-3104, ext. 14, if you have any questions or require additional information. Department: Engineering Issue Contact: Marc Virata Topic: Construction Plan Number: 19 Created: 11/5/2004 [7/26/05] The overhead electric doesn't appear on the plans anymore. [2/15/05] The note on the plans is not clear as to where are the limits of undergrounding of the overhead electric. [11/5/04] There needs to be an indication on the plans that the overhead line adjacent to the site is to be undergrounded with the development. In addition, the work on Lemay south of the site will cause additional sections of line to be undergrounded. Please indicate on the construction plans where the undergrounding in proposed to begin. Page 4 Topic: Landscape Plan Number: 44 Created: 11/5/2004 [8/3/05] Repeat comment. Appears to still be relevant. [11/5/04] Phase lines should be shown on the Landscape Plans if the project is to be phased. Otherwise, the installation of landscaping or securing with a letter of credit will apply to issuance of any certificate of occupancy in the entire development (Planting Note #18 on the Landscape Plan). Also, Note #18 should be revised to state, in part: "..... Installed or secured with an irrevocable letter of credit in the amount of 125% of the estimated cost of the materials and installation of the landscaping prior to issuance of a Certificate of Occupancy in each identified phase of development". The last part of the above note applies only if the project is to be phased. Number: 82 Created: 2/24/2005 [8/3/05] Repeat, just for reference. [2/24/05] The language proposed in the Design Team Responses to Comments letter for the installation and maintenance of trees is acceptable and should be added to the Landscape Plan, replacing Planting Notes 19, 20, and 20. This note should be expanded, however, to state who is responsible for the on -going maintenance of the trees. Is the developer still going to install the street trees adjacent to the common, open space areas? Lastly, the "first" Planting Note 20, regarding phasing, should remain on the plan. Topic: Utility Plans Number: 80 Created: 2/17/2005 [8/3/05] Repeat, just for reference. [2/17/05] Len Hilderbrand of Xcel Energy indicated that they have a 4" PED pounds medium system and a 6" intermediate pounds system gas line along the easterly edge of South Lemay Avenue in this area. This system is adequate to serve the proposed subdivision. Page 3 Number: 99 Created. 8/3/2005 [8/3/05] Carl Jenkins of the U.S. Postal Service indicated that centralized mail delivery, using a minimum of 5 centralized box units (CBU's - 4 Industry Type III boxes and 1 Industry Type I box) is required. Please revise the plan to show the required CBU locations as approved by the U.S. Postal Service. In all cases the CBU's must be located in the public right-of-way or a designated easement. Be advised that the responsibility of purchasing and maintaining the CBU's with concrete pads is that of the owner/developer/builder/HOA. Prior to occupancy within the development approved mail receptacles must be in place. A delivery agreement will be in place prior to any delivery of mail. Please contact Carl Jenkins, Growth Coordinator, U.S. Postal Service, 301 East Boardwalk Drive, Fort Collins, CO. Phone #970-225-4130, cell #970-214-3668, fax #970- 225-4139. Number: 100 Created: 8/3/2005 [8/3/05] Judy Green of the Lorimer County Assessor's Office indicated that according to the site map, this parcel belongs to Lemay Avenue, LLC. Is this correct? Also, they show a residence built in 1954 with an outbuilding. Are the buildings staying and, if so, which lot/tract will they be located on? Or have they been demolished? Number: 102 Created: 8/3/2005 [8/3/05] All of the lot numbers, consistent with the plat, must be shown on the Site & Landscape Plans. Number: 103 Created: 8/3/2005 [8/3/05] There is a short dashed line behind Lot 18 on Sheets 1, 3, 5, 7, 9, and 11 of the Site & Landscape Plans. What is this line? Number: 104 Created: 8/3/2005 [8/3/05] How high is the wooden fence, with stone .& brick columns, along South Lemay Avenue?.The height is not indicated on Sheets 1, 2, 4, and 6 of the Site Plans.

Torgerson Architects Date: 08/03/2005 c/c Troy Jones 223 North College Avenue Fort Collins, CO. 80524 Staff has reviewed your submittal for LEMAY AVENUE ESTATES - FINAL PLANS, and we offer the following comments: ISSUES: Department: Current Planning Issue Contact: Steve Olt Topic: Bike Trail in the Erosion Buffer Zone Number: 79 Created: 2/17/2005 [8/3/05] Repeat, just for reference. [2/17/05] Craig Foreman of the Parks Planning Department indicated that the trail extension (on the Lemay Avenue Estates property) will not be designed nor constructed by the City of Fort Collins. This is the responsibility of the development. The trail should be brought to the north property line of Lemay Avenue Estates, at the northeast corner, and the City will connect from there to the main trail. This is the typical process used for numerous trail connections. Topic: General Number: 9 Created: 11/4/2004 [8/3/05] Repeat, just for reference. [2/24/05] Carry-over comment. The trail will now occur between Lots 20 & 210 continuing to the north property line at the northeast corner of this development. The developer will be responsible for the design and construction of this trail to the property line, where the City will pick up responsibility. [11/4/04] Craig Foreman of the City Parks Planning Department has indicated that the City trail will be located just north of this development on the west side of Stanton Creek. From Woods Landing Drive, between Lots 21 & 22, the City should have a 5' wide sidewalk to the north property line for a trail connection in Tract 0. Page 1
