airport. Additionally, the preliminary budget does not include a contingency since this report evaluates the relative costs of the four alternatives. A construction contingency of at least 25% is recommended to account for unforeseen design or construction requirements which may be identified once design begins.

This alternative adds 30 parallel parking spaces on the north side of the road and allows vehicles to pass through on the left side of the road. The current one-way road is approximately 20 ft wide and would be widened by 2 ft on the north side to accommodate parallel parking along the north side of the road. The Okaloosa County Land Development Code requires a minimum lane width of 12 ft adjacent to parallel parking spaces and a width of 10 ft for the parallel parking space, requiring a total pavement width of 22 ft. Concrete would be proposed for the new pavement due to the narrow width of ‘) { oKaLoosa county) AIRPORTS North 0 20 40 GRAPHIC SCALE iM FEET ea AVCON AYCON, INC.

Placing and compacting asphalt of this width would be difficult and the appearance of this new asphalt would more than likely be poor. The new curbs will be integral with the widening concrete because it would be economical from a construction standpoint to extend the concrete to the edge of the existing road. Several existing utilities may be affected by this lane widening, including | underground electrical, underground fiber optic communications, and _ irrigation. Existing utilities that would be affected are depicted in Photos 4 and 5. Based on coordination with airport staff, it is understood that the existing fiber optic infrastructure is owned by Sprint and serves as the primary trunk line for the airport. This line also serves Eglin Air Force Base. Relocation of this line may require moving it approximately 2 ft to the north without cutting Rie re eee aes the line if the line has enough slack to do so. Photo 3: Alternative No. 2 The relocation could be much more costly if the line has to be cut and relocated. Fiber Optic Cable splices may also be functionally and operationally unacceptable to the customer base. For these reasons, the preliminary project budget for this task included in Table 2 assumes that the existing line would be relocated without cutting. This lane widening will require removal/relocation of the existing palm trees along the north edge of the terminal loop road and modification of the existing concrete stormwater flumes. A concrete stormwater flume is depicted in Photo 6. Photo 6: Concrete stormwater flume Photo 4: Sprint fiber Photo 5: Gulf Power optic utilities transformer Concrete curb improvements are proposed on the east side of the parallel parking spaces to organize the traffic into the left drive-through lane. The FIDS message board location is proposed over the terminal loop road on the west end of the proposed parallel parking spaces to provide visibility to all of the CWA parking spaces. However, the easternmost parking space would be approximately 680 ft from the FIDS message board and may be difficult to see from the easternmost spaces. The communication line improvements for the Cell Phone Waiting Area Feasibility and Alternatives Analysis September 2013 FIDS would be installed from the FIDS location to the existing fiber optic communication panel location just west of the Credit Card Parking Lot entrance/exit. The run length for this alternative is estimated at 550 If. No new parking lot lighting is proposed as the proposed area has adequate lighting from the existing parking lot along the south edge of the terminal loop road. The proposed additional impervious area is approximately 1,400 sf which is less than the impervious area threshold amount of 4,000 sf to trigger a state stormwater permit through the Northwest Florida Water Management District. Therefore, no stormwater permit application is anticipated with this alternative. The existing stormwater infrastructure will be maintained, including concrete flumes and curb inlets, to convey stormwater to the existing swale located north of the terminal loop road. The infrastructure improvements for Alternative No. 2 generally include: FOMMOOWD and Removal of existing concrete curb and relocation of existing palm trees, Relocation of existing utilities and irrigation lines, Shoulder grading and sodding, Placement of new concrete pavement with integral concrete curbs, Placement of pavement markings, Placement of vehicular signage, Modification of existing concrete stormwater flumes, Installation of FIDS message board and communication and power infrastructure, Installation of communication and WiFi access point infrastructure A preliminary project budget for Alternative No. 2 is provided below in Table 2.

Although the parking spaces provided by this alternative are less than half of the desired 30 parking spaces for the CWA, the existing concrete curb and asphalt pavement orientation is ideally set up to accommodate parallel parking so no curb or asphalt modifications are required. Tubular markers are recommended to highlight the existing crosswalks as identified in the exhibit. The FIDS message board would be located on the east end of the parking area to provide visibility to all of the CWA users and is positioned to straddle the existing sidewalk. A clear height of 8 ft from the bottom of the message board to the sidewalk is recommended so the existing sidewalk remains unobstructed and still accessible to pedestrians. The FIDS message board is approximately 450 ft from the westernmost parking space so it may be difficult to see from these spaces. The communication improvements for the FIDS are proposed to run from the existing fiber optic infrastructure at the Baldwin Building to the FIDS message board. The estimated length of the cable run length is approximately 175 If. No new parking lot lighting is proposed since the area is illuminated by existing parking lot lights along the north side of the terminal by-pass road. This alternative would require that drivers make an entire loop around the terminal loop road to access the airport terminal. The development time and cost appears to be minimal for this alternative due to the relatively limited infrastructure improvements.

Alternative No. 4 includes two variations (4A and 4B) with each variation providing a slightly different parking layout. Each variation is analyzed separately below. Alternative No. 4A provides 16, 45-degree parking spaces which are less than the desired number of 30 parking spaces. A 3-ft wide concrete island is proposed to separate the traffic on the terminal loop road from the parking activities of the CWA users. The Okaloosa County Land Development Code requires a 12-ft wide access aisle adjacent to 45-degree parking stalls, as depicted in the exhibit. Several existing utilities have been identified in this area which include fiber optic communication lines, irrigation lines, Sprint communication lines, and electrical transformer and underground power lines.
