We will keep all of this in mind as the project evolves. Thanks! Nick Haws, PE, LEED AP NORTHERN ENGINEERING From: Marc Ragasa [mailto:mraeasa@fceov,coml Sent: Wednesday, August 19, 2015 2:49 PM To: Nick Haws <nick@northerneneineerine.com> Subject: RE: Uncommon flood proofing Nick, As proposed, the gate would be allowed to swing into the public ROW. Since the gate in the open and closed position will not be in the ROW, the gate is acceptable. We will have language in the Development Agreement to discuss details about securing the gate, operation during a flood and replacing the door if it fails to comply. It will not need an encroachment permit for this gate. One thing to note, the gate, in the open position appears to affect sight triangles out of the parking garage to the alley. This has been something discussed with Martina at the project review.

The dual swing flood gates are proposed at the location with the green asterisk. While the pictured flood barriers (second page) are not exactly what we would employ, the general specifications would be similar. 1 --N These gates would be pinned to the side of the building, contained entirely on private property (keeping in mind the 5' multipurpose easement / building setback from the alley R.O.W.). The only "encroachment" would be a 7-ft maximum arc swing into the alley as the gates were being closed in an emergency flood event. The current thinking is that these would be manually operated and tamper proof. I hope this further explanation and supporting graphics helps illustrate whey an encroachment permit seems unnecessary.

We haven't spoken to Ricky yet, so he will have the final say. We think this would need an encroachment permit, however since it is a revocable permit, there could be safety issues if this were to be revoked. Do you know what type of gate it will be? Will it be manually operated? How will the locking mechanism work when it is in the open position? I think more details would help when presenting this to Rick. Thank you, Marc Ragasa City of Fort Collins Engineering Department 970-221-6603 mragasa(pD-fcgov.com Model: HSS-550 (Single), HPS-555 (Paired) Hinged Flood Barriers PS DOORS Flood Protection Solutions Hinged Flood Barriers are designed specifically for the height of water protection you require. The barriers are permanently installed and stored in the open position. During flooding, the Hinged Flood Barrier is swung closed and is latched, providing flood protection.

The HSS-550 is a single swing flood barrier and the HPS-555 is a "paired swing" flood barrier. Depending upon the layout of your facility, the offering of a single or paired hinged barrier allows for flexibility when designing the flood protec- tion system. Standard Features: • Available in mild steel, stainless steel, or aluminum. • Compression seal —requires no compressed air for activation. • Latch system designed for simple, quick deployment. Application Use: • Walk doors. • Sectional doors. • Retaining walls. • Driveways. • Store fronts. • Interior hallways/room.
