If you have questions about any comments, you may contact the individual commenter or direct your questions through your Development Review Coordinator, Brandy Bethurem Harras, at 970.416.2744 or bbethuremharras@fcgov.com. Comment Summary: Department: Engineering Development Review Contact: Marc Virata, 970-221-6567, mvirata@fcgov.com Topic: General Comment Number: 1 11/06/2018: FOR APPROVAL: It is my understanding that PFA is interested in ensuring that during the course of construction, they would have access to the old section of roadway as a means to have access to the CDOT weigh station. We'll want to coordinate with PFA on their access needs during the course of construction. RESPONSE: The project sequencing will ensure that emergency access will be achieved during all phases of the project. This may require an all-weather surface at the intersections, but this can be achieved with the existing base material of the existing frontage road. It is anticipated that continued discussions and game planning will occur throughout the construction process to ensure that both construction activities and emergency services are maintained. Further mapping and sequencing can be established at time of the DCP. Comment Number: 2 11/06/2018: FOR APPROVAL: The temporary frontage road connection to the existing frontage road at the southern boundary of the proposal has a roadway design more consistent with a local street with 165' radii and 100 foot tangents between curves. Is the intent of the design to be permanent and the viewpoint is that local street design characteristics can be used here? I would believe this is acceptable under the premise that the buildout of the PUD would demonstrate traffic would not be envisioned to ever go south to this section of roadway. RESPONSE: CDOT has indicated that further takings would occur at some point in the future. The current alignment at the terminus of the Collector Section would align with these future takings. Whether this ever happens, the traffic counts at this location will only require a local street, which the current alignment adheres to all the local street requirements. Comment Number: 3 11/06/2018: FOR APPROVAL: With only the right-of-way being dedicated at this time, would there be an issue of the utility crossings being installed at this time with portions of utility being outside of a prescribed easement or right-of-way? RESPONSE: The utilities are extended outside of the current right-of-way, but will be within the required Utility Easement that will be included in the Phase I Replat. Comment Number: 4 11/06/2018: FOR APPROVAL: From the depiction on Sheet C2.01, there appears to be an issue of a storm crossing (culvert #2) of the roadway that is shallow with a little more than 2 feet from the top of pipe to the finished grade. Also, with the assumption that finished grade is indicative of top lift, there would be an interim condition of even less than the ideal cover. Subsequent sheets however appear to show more adequate cover. RESPONSE: The storm culvert will have a minimum of three feet of cover at the flowline in the roadway’s ultimate condition. Profile has been fixed to show correctly. Comment Number: 5 11/9/2018 UPDATE: To further expand on this comment, Chad Crager has confirmed that not constructing the top lift of asphalt is acceptable to the City. Maintenance as described in the project narrative is acceptable. RESPONSE: Acknowledged. 11/06/2018: FOR APPROVAL: The original comment below was prior to further discussions with Chad Crager. Chad is coordinating further on this and I'll be providing further updates on this. ORIGINAL COMMENT In checking with Tom Knostman with City Streets Pavement Manager, the indication in the project narrative that the interim road without final lift would be maintained by the City should have further discussion/verification. Tom can see a scenario that without top lift, the City could at the conclusion of the warranty period, be responsible for crack sealing and pothole spray patching of the bottom lift, but any failures to the roadway itself beyond normal wear and tear he would envision the applicant would still be responsible in this interim condition. Understanding the duration in which the interim section would be in place before the permanent section would be helpful as well. Tom notes that snow clearing at a priority level of a local roadway would not necessarily be a concern as a local roadway, it should be noted that this would a priority 4 classification (the lowest) and would have the least level of maintenance in that regard. Comment Number: 6 11/9/2018 UPDATE: I've had conversations with the City Attorney's Office, and their initial reaction is that the deed of dedication for right-of-way is awkward to be the mechanism to place stipulations such as the maintenance/repair guarantee and other language that would traditionally be in a development agreement. At this point, the City Attorney's Office believes a development agreement would be the best mechanism instead of covering concerns under the deed of dedication. I will look to provide further confirmation on this item with further input from CAO. RESPONSE: A Development Agreement seems appropriate for this project. 11/06/2018: FOR APPROVAL: I will need to have further discussion on the maintenance and repair guarantee aspects for the interim roadway. I'll look to follow-up with our City Attorney to verify if there is a manner in which the deed of dedication can have the maintenance and repair language be part of the dedication, which would be the most unusual, but I think the simplest way to address this, for not having a plat or a development agreement (presumably) which would normally be the mechanism to have this. Also, I would need to follow-up further on whether the dedication can/should have the details behind the pavement condition/City maintenance responsibilities, etc. Comment Number: 7 11/06/2018: FOR APPROVAL: In addition to the item above, one of the aspects I'm still a little hazy on is the intent behind the maintenance for the existing portions of frontage road that is not being rebuilt and this road project is tying into on both ends. Are these not being proposed to be City maintained, but this middle portion would be? Or, is it also being proposed that these sections be City maintained but then they are not in City right-of-way currently? RESPONSE: The existing portion of the Frontage Road would remain as currently maintained by CDOT until the devolution from CDOT to the City occurs, at which time, the maintenance of the remaining portion of frontage roadway would be the responsibility of the City. Comment Number: 8 11/06/2018: FOR APPROVAL: It is presumed that DCP for the construction of the project will be needed. RESPONSE: We would agree. Comment Number: 9 11/9/2018 UPDATE: This comment is considered resolved as Light and Power has confirmed that they will not provide lighting on the roadway at this time and this is not being sought by the applicant as well. RESPONSE: Correct. 11/06/2018: FOR APPROVAL: Will there be roadway lighting for City streets that is being anticipated with the interim road section? Comment Number: 10 11/09/2018: FOR APPROVAL: Please provide within the project narrative a project schedule that gives estimated dates and timeframes that lists the proposed construction of the road, CDOT's work, the construction of the permanent widened road, removal of the old road, etc. RESPONSE: An approximate project schedule has been included within the project narrative. Department: Stormwater Engineering Contact: Heather McDowell, 970-224-6065, hmcdowell@fcgov.com Topic: General Comment Number: 6 11/01/2018: FOR APPROVAL: This project proposal includes the construction of a new frontage road at the southwest quadrant of the Prospect and I-25 interchange. This proposal will realign the existing frontage road thereby creating a new roadway through the property and abandon and remove sections of the existing frontage road. As such, this project does not meet the definition of an “Excluded Site” per Part I, Section E.4.a.i of the MS4 permit. Therefore, this project proposal will need to include a drainage analysis that quantifies the overall existing imperviousness and proposed imperviousness. If the overall imperviousness does not increase by more than 1000 sf, then quantity detention for the roadway project will not be required. If there is an increase of imperviousness by more than 1000 sf, then complete drainage calculations and quantity detention will need to be provided. Regardless of any added imperviousness, the proposed drainage swales and culverts will need to be sized using an approved drainage analysis methodology. In addition, because of the MS4 permit requirements, standard water quality will need to be provided for the new roadway. The City will allow that the LID provisions of the stormwater requirements be provided with future lot development. RESPONSE: Drainage report and Impervious exhibit area provided. Contact: Jesse Schlam, 970-218-2932, jschlam@fcgov.com Topic: Erosion Control Comment Number: 1 10/24/2018: INFORMATION ONLY: The site disturbs more than 10,000 sq. ft. and therefore Erosion and Sediment Control Materials need to be submitted. The erosion control requirements can be located in the Stormwater Design Criteria under the Amendments of Volume 3 Chapter 7 Section 1.3.3. a copy of the erosion control requirements can be found at www.fcgov.com/eroison . RESPONSE: An erosion control report and escrow have been included within this submittal. Comment Number: 2 10/24/2018: INFORMATION ONLY: Based upon the area of disturbance, State permits for stormwater will be required since the site is over an acre and should be pulled before Construction Activities begin. RESPONSE: Acknowledge. Comment Number: 3 10/24/2018: FOR APPROVAL: Please resubmit Erosion Control Plans based upon redlines to meet City Criteria. RESPONSE: Plans have been submitted. Comment Number: 4 10/24/2018: FOR APPROVAL: Please submit an Erosion Control Report to meet City Criteria. RESPONSE: Erosion Control Report has been submitted. Comment Number: 5 10/24/2018: DEVELOPMENT AGREEMENT: Please submit an Erosion Control Escrow / Security Calculation to ensure the Erosion Control Plans to meet City Criteria. RESPONSE: An Erosion Control Escrow has been submitted. Department: Environmental Planning Contact: Stephanie Blochowiak, 970-416-4290, sblochowiak@fcgov.com Topic: General Comment Number: 1 11/06/2018: INFORMATION ONLY: Generally an Ecological Characterization Study (ECS) is required by City of Fort Collins Land Use Code (LUC) Section 3.4.1 as the site is within 500 feet of LUC defined natural habitats and features (wetlands, ditches, active raptor nests). However, if the project does not significantly change drainage patterns to the wetlands to the south, then the ECS can be deferred at this time for this small cornfield area. And ECS is needed if and when a development proposal is submitted for the parcels further south. The ECS is due a minimum of 10 days prior to PDP submittal. RESPONSE: The wetlands will not be effected within this phase of the overall project. Comment Number: 2 11/06/2018: FOR APPROVAL: Please clarify what impact if any would occur to any and all existing ditches, swales, wetlands and trees due to the scope of the proposed road project. Comment Number: 3 11/06/2018: INFORMATION ONLY: Note there are several active nests including active raptor nests in this general area especially to the west and south of this corner parcel. RESPONSE: Acknowledged. Comment Number: 4 11/07/2018: FOR APPROVAL: Will there be lighting? Note in regard to outdoor lighting, especially LED light fixtures, cooler color temperatures are harsher at night and cause more disruption to circadian (biological) rhythms for both humans and wildlife. Warmer color temperature (warm white, 3000K or less) for any LED light fixtures is preferred. Please also consider fixtures with motion-sensing or dimming capabilities so that light levels can be adjusted as needed. Site light sources shall be fully shielded and down-directional to minimize up-light, light spillage and glare [see LUC 3.2.4(D)(3)]. Thank you in advance for supporting City of Fort Collins Night Sky Objectives. For further information regarding health effects please see: http://darksky.org/ama-report-affirms-human-health-impacts-from-leds/ RESPONSE: Lighting will not be included within this phase. Comment Number: 5 11/07/2018: FOR APPROVAL: Ensure natural resource protection measures are in place including for any wetlands and/or trees. These resources should be protected during demolition of existing roads and construction of the temporary roadway. No tree removal is to occur. Right of Way dedication may need to memorialize agreements for natural resources and stormwater. RESPONSE: There are no existing trees within the area being demolished or the area of construction. Comment Number: 6 11/07/2018: FOR DCP: Environmental Planning will ensure limits of the road project impacts are clear and that natural resources are protected during construction of this temporary road project. Environmental Planning and Forestry will attend the DCP meeting. RESPONSE: Acknowledged. Department: Forestry Contact: Molly Roche, 224-616-1992, mroche@fcgov.com Topic: General Comment Number: 1 11/06/2018: FOR APPROVAL: There are existing trees within the project area. These trees should be protected throughout the construction period of this project. Please include the City of Fort Collins Tree Protection Notes to the site/utility plans. Provide a note that states: EXISTING TREES TO REMAIN AND BE PROTECTED. RESPONSE: Standard note added to Existing Conditions & Demolition Plan sheets. In addition, prior to DCP provide narrative regarding existing tree retention and protection. If trees are to be retained, please include the City of Fort Collins Tree Protection Notes to the site/utility plans. Provide a note that states: EXISTING TREES TO REMAIN AND BE PROTECTED. If trees are planned to be removed in conjunction with this road project, please schedule an on-site meeting with City Forestry to obtain existing tree inventory and mitigation information. This meeting should occur prior to next submittal. Existing, significant trees should be retained and protected to the extent reasonably feasible. Please note: any tree removal that occurs must be done by a City of Fort Collins Licensed Arborist. RESPONSE: There are no existing trees within the area being demolished or the area of construction. Department: PFA Contact: Andrew Rosen, 970-416-2599, arosen@poudre-fire.org Topic: General Comment Number: 1 10/29/2018: ACCESS >Access shall be maintained to the southbound weigh station and any other businesses at all times. >The Temporary Roadway before top-lift shall be constructed to support 40T RESPONSE: Access will be maintained at all times of the project either by the existing frontage road or the proposed frontage road. Department: Technical Services Contact: Jeff County, 970-221-6588, jcounty@fcgov.com Topic: Construction Drawings Comment Number: 1 11/06/2018: FOR APPROVAL: The City has moved to the NAVD88 vertical datum, and as of January 1, 2015, all projects are required to be on NAVD88 datum. Please provide the following information for the Benchmark Statement in the EXACT format shown below. PROJECT DATUM: NAVD88 BENCHMARK # w/ DESCRIPTION ELEVATION: BENCHMARK # w/ DESCRIPTION ELEVATION: PLEASE NOTE: THIS PLAN SET IS USING NAVD88 FOR A VERTICAL DATUM.
