The requirement to desigr the road and raise the road to 0.5% has numerous design and cost implications There are three connections for Ziegler Road that are used in the vertical design of the road The north connection at the intersection of Shallow Pond Drive (East side), the intersection at Trilby Road and the south connection of the road in the local street section that currently dead ends Exhibit A -To hold the intersection of Trilby and Ziegler at existing elevation - The cross slope in the intersection would meet requirements. The connection point back to existing pavement on the north end is over a foot above existing pavement. This exceeds the cross slope requirement on existing pavement sections ( 6.7% vs a max of 4%) This would require a grade beak or vertical curve to slope back to the existing pavement at Shallow Pond Drive. Placing a grade break or vertical curve would trap water on the street that cannot be drained by adding an inlet. Exhibit B-To hold the centerline connection at existing pavement on the north end of Ziegler - The intersection is at a saddle point. The affect is that the intersection lowers 1.11 which reduces critical pipe cover. Other affects include the cross slopes from centerline to flowline are below requirements for approximately 600 feet and the intersection does not drain properly The existing drainage pipe under the pavement has the minimum cover The addition of new pipes to drain the intersection would be elliptical and have less than minimum cover due to lowering the intersection In addition to the exhibit, we have also attempted to add a high point to the Ziegler Road. This would a crest vertical curve along the road. The addition of a vertical curve traps water on the north side of the curve We looked at the addition of Inlet In this new 'sag' area The depth available Is insufficient to drainage the sag The depth of the inlet is greater than the accompanying grades on the west side of the road therefore, The inlets do not daylight into pond or swale on our side of the road Therefore, we request that the centerline slope remain the same so that extensive reconstruction of the intersection is not required.

The dry utilities serving the Junior High School are being provided from Ziegler Road. To the best of our knowledge, there is no connection of these utilities with the utility easements running parallel to Homestead's south property line. While the LCUASS Design Figure specifies a 9-ft utility easement on each side of a residential local street, we are proposing a variance eliminating these easements around the proposed cul- de-sac. We feel justified in requesting the variance listed above. Eliminating the easements will still meet the needs of the utility providers and future residents of Lots 9 and 11. This variance will not be detrimental to the public health, safety or welfare, nor should it pose increased maintenance costs to the City of Fort Collins or any franchised utility company. Please do not hesitate to contact us if you have any questions. Sincerely, e.. 2/4E r Micha J. McR elrts, P.E.

Marler" <amarler@jvajva com> To: "Susan Joy (E-mail)" <sjoy@fcgov_com> Date: 1/11/05 4 35PM Subject: Ziegler Cross Sections Susan - Here are 3 cross sections plots for Kinard. The 3 sheets are laid out similar. They show the same cross section with 3 different scenarios The existing centerline and east flowline are labeled in red. The proposed condition is drawn in green. New cross slopes are shown on each cross section. Each scenario is labeled on the cross section and what exhibit it relates to. This clearly shows that leaving the existing street slope is the best alternative with all the scenarios. The first file shows cross sections at the north connection on Ziegler. The top cross section shows what the road will look like if we kept it at the current slope, 0.43% The mid cross section correlates with Exhibit A, with the intersection of Ziegler and Trilby held and the road sloping up towards the north property line The bottom cross section on the sheet correlates to Exhibit B, the north connection point is held and the road slopes down toward the intersection File 2 shows a cross suction near the right lane taper File 3 shows cross sections of the intersection per I would be happy to discuss these with you and the City staff.

March 17. 2005 Ms. Susan Joy City of Fort Collins Engineering Department 281 North College Avenue Fort Collins. Colorado 80521 RE: Utility Plans for Poudre School District Trilby Road and Ziegler Road (Homestead/Kinard JHS Cul-de-sac) Request for Variance Susan: This letter is in regards to the Homestead/Kinard JHS Cul-de-sac project, and in particular, to request a variance on the utility easements adjacent to the proposed cul-de-sac. The owner for this project is the Poudre School District. The contact person for the school district is Ed Holder of the Planning, Design and Construction Department. The Larimer County Urban Area Street Standards (LCUASS) have been referenced in this letter. Specifically, a variance is being requested from Figure 7-9F for the typical section of a Residential Local Street. At the time Homestead P.U.D. was master planned and designed, it was predicted that Old Legacy Drive would continue south of the development to provide a connection with future developments. The property immediately south of Homestead; however, was recently purchased by the Poudre School District and is currently being designed for Kinard Junior High School. The south connection provided by Old Legacy Drive is no longer needed. As part of this project, a Cul-de-sac will be constructed at the end of Old Legacy Drive. This cul-de-sac will provide a place for south bound Old Legacy Drive traffic to turn around, and it will provide emergency access to Kinard Junior High School. According to Figure 7-9F, the cul-de-sac project will require the dedication of new right-of-way and the dedication of a new 9' utility easement around the cul-de-sac. The new right-of-way and 9' utility easement will occupy portions of Lots 9 and 11 of the Homestead P.U.D., and a portion of the property now owned by the school district. The 9' easement on the east side of the cul- de-sac and along the school district's property will provide no additional service or availability to any additional or future consumer(s). The 9' easement on the west side of the cul-de-sac, likewise will provide no additional service, either currently or in the future. It will, however, encroach on an existing irrigation easement, and will literally incorporate a portion of an existing. irrigation manhole. In order to avoid this conflict by providing the irrigation company its desired 20' easement, the cul-de-sac will have to shift approximately 25' to the south. A shift of this magnitude will have a serious negative impact on the Junior High School site. Dry utilities are currently in place within the existing 9' utility easements, and terminate at the south end of Old Legacy Drive (both sides). Before the cul-de-sac is constructed, approximately 52 linear feet of Old Legacy Drive will have to be demolished and removed. At that time the dry utilities will have to be abandoned back to approximately the same location. It is our opinion that even with the dry utilities being shortened by 52 feet, they will still be able to provide service to Lots 9 and 11. 420 SOUTH HOWES, SUITE 202 / FORT COLLINS, COLORADO 80521 / 970.221.4158 / FAX 970.221.4159
