Since that time the Engineering and Stormwater Departments have met with the applicant and discussed some of our concerns regarding the alley configurations and the drainage. At that meeting an agreement was reached on an alley configuration that would satisfy all those involved The Engineering and Stormwater Departments are asking that the following (modified) conditions be placed on this project at the time it goes to the Planning and Zoning board for final approval. The conditions should read as follows: Condition 1: For the alleys to remain public right-of-way (ROW) the alleys needs to be designed to meet one of the following designs: 1. An alley that slopes to one side shall be accepted if it is constructed with a driveover curb and gutter on the down (low) side so that the majority of the drainage flows are confined to the alley. The concrete driveover curb and gutter should meet city standards or be of acceptable design, if a higher curb is used. At any location where the flows can not be contained in the alley ROW drainage easements and appropriate grading shall be provided. The high edge of the alley should have a concrete edge that is a minimum of 1 foot wide and 8 inches thick. The remaining portion of the alley can be of an asphalt pavement section. The entrance to the alley off of the City street needs to have a street type configuration ( a curbed intersection with handicap ramps). 2_ An alley that slopes to one side may also be accepted if it is constructed with 281 North College Avenue • I'O. lim 7;80 • Port Collins, CO 80722-0580 • (970) 221-6(,05 a v-pan provided on the down (low) side. Adequate easements need to be provided for drainage flows outside of the alley ROW with consideration taken for the effects due to blockage of the flow by obstacles ( such as fences, sheds, landscaping or changes in the backlot grading). The v-pan should be a minimum of 2 feet in width, 8 inches thick and have a maximum depth of/4 of an inch. The high edge of the alley should have a concrete edge that is a minimum of 1 foot wide and 8 inches thick The remaining portion of the alley can be of an asphalt pavement section. The entrance to the alley off of the City street shall have a street type configuration ( a curbed intersection with handicap ramps). A suitable transition design from the v-pan to the curb is needed to keep flow from going over the sidewalk as it exits the alley. It would also be acceptable for the alleys to become private if they do not wish to conform to the above requirements The stormdrainage flows would still need to be contained in the alley and/or provide adequate drainage easements and meet stormwater criteria. Condition 2: The Pleasant Valley and Lake Canal at the Southwest corner of the property has experienced flooding in the past. The potential for a spill should be investigated and if needed a conveyance system that would provide for the safe discharge of these flows across the Minatta property should be designed and included in the final Utility plans for the Siena P.U.D. These conditions are requested for the Engineering and Stormwater Departments to support this project for final approval. ccGary Diede, TOP Group Leader John Minatta, Developer Craig Houdeshell, RBD Bruce Hendee, BHA City of Fort Collins Transpe- `1tion Services Engineering Department MEMORANDUM TO Ted Shepard, Senior Planner FROM Mike Herzig, Development Review Manager �,` l( Sheri Wamhoff, Development Review Engineer - Engineering Basil Harridan, Development Review Engineer - Stormwatef DATE February 16, 1996 RE Siena PUD (formerly Overland Ridge PUD) and the Planning and Zoning Board decision on the Final PUD submittal The alley design submitted for Final PUD approval by the Planning and Zoning board is unacceptable The alleys are currently designed so that the entire alley surface slopes to one side placing drainage flows 6-10 feet onto private lots. This is not an acceptable design. By placing a portion of the drainage onto private property the City can not keep the lot owners from placing obstacles on their property that might obstruct this flow. This could include such things as fences, sheds, landscaping or changes in the back lot grading. For this reason the Engineering and Stormwater Departments are asking that the following conditions be placed on this project at the time it goes to the Planning and Zoning board for final approval. The conditions should read as follows: Condition 1. For the alleys to remain public right-of-way (ROW) the alleys needs to be designed to meet one of the following designs: I An alley that slopes to one side may be constructed if driveover curb and gutter is used on the down (low) side so that all the drainage flows are confined to the alley. The concrete driveover curb should meet city standards or be of acceptable design, if a higher curb is required The high edge of the alley should have a concrete edge that is a minimum of 1 foot wide and 8 inches thick The remaining portion of the alley can be of an asphalt pavement section. The entrance to the alley off of the City street needs to have a street type configuration ( a curbed intersection with handicap ramps). 2 A `V' shaped alley configuration may also be used. This should be constructed entirely of concrete with a concrete v-pan down the center of the alley. 281 North College Avenue • P.O. Box 580 • Fort Collins, CO 80522-0580 • (970) 221-6605 Again all stormdrainage flow must be contained in the alley ROW. it would also be acceptable for the alleys to become private if they do not wish to conform to the above requirements. The stormdrainage flows would still need to be contained in the alley and in the location where the stormwater flows, such as a v-pan, would need to be concrete . Condition 2: The Pleasant Valley and Lake Canal at the Southwest corner of the property has experienced flooding in the past. The potential for a spill should be investigated and if needed a conveyance system that would provide for the safe discharge of these flows across the Minatta property should be designed and included in the final Utility plans for the Siena P.U.D.

The unit costs comparable to average unit costs in the industry. Remove vertical curb and gutter - $2.41 per quare foot Replace with drive approach - $22.47 Lineal Foot (this includes 4 L two car 20 foot feet of apron behind the curb head.) I assume6 feet of removal and driveway with 6 feet of transition, requiring replacement with a drive approach. oved Since this is new asphalt pavement the curb and ga to against the asphalt r can be rem without damaging the asphalt and the new curb p led edge, so no asphalt repair costs are included. As you are aware, there was confusion as to what was being required by the Peakview plans for this area as a result of that development, the your City will participate in the replacement of the curb and gutter development. We are willing to share the co to $800.00, subject a drive approach to curb for lot 43 (2769 Pleasant alley Road) up the condition that we are providged with the gutter for lot 44 since ost invoices. We 11 not participate in replacement of the curb and has access from the alley. Please let me know when the work has been completed and send the invoice to me. Thanks, Dave >>> "john minatta" <mjnatt DAarthlink.net> 06/23/03 10:16AM »> Dave I saw Vicki at the site last week and spoke to her about this issue.
