INTRODUCTION

The City of Ferndale commissioned this study to explore the feasibility of aparking structure east of Woodward Avenue along Nine Mile Road. Recentdevelopments and new nightspots in the area have increased the demand forparking spaces. In addition, the Ferndale Library is being renovated and expanded. The expanded library building will include meeting rooms that will be used to host more events and meetings.

The sites identified as potential locations for the parking structure are shown in Figure 1. Site #1A is the existing surface lot immediately west of the existingLibrary building. Site #1B encompasses the Site #1A Lot and the existingmunicipal surface lot south of Troy Street. Site #1C adds the triangular shapedprivate surface lots just north of Saratoga Street. Site #2 is the existing municipalsurface lot located between the Library and City Hall.

Challenges to construction of a parking structure on these sites include:

� The individual sites are limited in size which limits the design options on each site. One of the seven options requires an additional residentialproperty, located adjacent to Site #1C.

� The Library is expanding the building within the existing library site.

� Troy Street is an important connector between Woodward Avenue and the City Hall / Police Station. Two of the seven options require the closingor rerouting of Troy Street.

� To enliven the area along Nine Mile Road and help encourage additional development, grade level retail / commercial space isdesired.

Carl Walker has prepared conceptual parking structures designs with a targetednet gain of 200 to 250 parking spaces. This report presents the seven mostpromising concepts. The designs presented are conceptual in nature. Detailedengineering studies have not been performed. The actual number of spaces in the structure will vary due to necessary operational or structural elements such as shear walls necessary in a pre-cast structure, electrical rooms, etc. Included inthis report are engineering sketches of the parking structure concepts,construction cost estimates, and Operating and Maintenance cost estimates.

DESCRIPTION OF OPTIONS

Site 1A – Option 1

This option is contained within the boundaries of the municipal surface lot west of the Librarybuilding. The structure has a footprint of about 124’ x 190’ which covers the entire site. Theentry and exit point is along Nine Mile Road.The drawing to the left depicts the footprint ofthe structure. The appendix contains more detailed presentations of this and all theoptions.

The structure has six total parkinglevels and five of the levels are supported. The floor of the uppermost level of the parkingstructure would be about 57 feet

above existing grade level. Because the length of the site islimited each parking bay, is sloped upwards approximately 5’-6”.Both long sides of the structure have sloping floors. The floors on the narrow ends are ‘flat’, sloped only for drainage.

The circulation system is called a singlethreaded helix design. There is a two-way traffic circulationpattern and up-bound and down-bound traffic share thesame driving route. A driver parking in the uppermost space must pass by every space on the way up, and on the waydown. The single threaded helix design is best suited for visitors. Regular users like employees soon tire of the numberof turns required to circulate to the top of the structure. The five supported levels is the maximum acceptable height for a single threaded helix design.

The parking spaces are shown at 9’-0” wide set at 90º to the drive aisle.Americans with Disabilities Act (ADA) accessible spaces will be required but arenot shown on these conceptual plans. A stair and elevator tower is shown in the northeast corner of the structure near Nine Mile Road. A second stair tower isshown in the southwest corner of the structure.

This structure conceptually encompasses 337 parking spaces. Displaced are 67 existing spaces, for a net gain of about 270 spaces. ADA accessible spaces arenot shown on these concept level designs, slightly fewer spaces will actually be realized.


4

Site 1B – Option 1

This option requires the closing / relocation ofTroy Street. Traffic could be relocated aroundthe structure to Saratoga Street. The relocationwill infringe on the adjacent residential propertyalong Saratoga Street. Acquiring at least a portion of the property would be required.However, if Troy Street can be closed acquiringthe property would not be required.

Entry and Exit lanes are shown on the north andsouth ends of the structure. The entry / exit portal is set back from Nine Mile Road. Theremaining space could be developed as a civicplaza or park. A stair / elevator tower is shownin the northeast corner. A stair tower is shown inthe southwest corner.

Vehicle circulation again uses a two-way trafficflow. Parking spaces are 9’-0” wide set at 90º tothe traffic flow. The concept structure has four parking levels total and three of the levels are supported. Approximately 386 spaces are in the structure. Displaced are about 132 existing spaces resulting ina net gain of about 254 spaces.

The option employs the same single threaded helix designbut lengthens the structure to about 300 feet. Because of the added length; only one of the parking bays needs to be sloped. The west bay is sloped; the east bay could be essentially ‘flat’, sloped only for drainage.


5


This option also requires the closing of Troy Street.The structure is pulled closer to and parallel with Nine Mile Road. The resulting dog-leg footprintallows for longer ramps. The longer ramped parking bay allows the first supported level to be about 12 feet above grade. Approximately 3,900S.F. of retail space is incorporated on the groundlevel facing Nine Mile Road. The 12 foot floor to floor height produces a ceiling height of about 9feet in the retail area.

A pedestrian pathway passes through thestructure at the grade level near the bend of the dog-leg. Two stair and elevator towers are shown; one at north end of the structure near the retail space and one on the west side of thestructure at the dog-leg bend. A stair tower islocated along the south end of the structure.Vehicular entry and exit lanes are at both ends of the structure; ingress and egress if from Nine MileRoad and Saratoga Street.

Circulation again is in a two-way traffic flow in a single threaded helixconfiguration, with 9’-0” wide parking spaces set at 90º to the traffic flow. Theconcept structure has three total parking levels and two of the levels aresupported. Approximately 393 spaces are shown in the structure. Displaced are 132 spaces resulting in a net gain of about 261 spaces. Due to the increasedlength of the structure, only two supported levels are needed to reach the 250 added spaces target.


6


Option 3 for Site 1B uses the entire length of Site 1spanning over Troy Street and two-way street trafficon Troy Street is maintained. Speed ramps, (rampswithout parking spaces) are located along the southend of the structure to provide vertical vehicularcirculation. The initial ramp rises to about 14 feetabove grade. The parking area then ramps up slightly to about 17 feet above grade. The structurespans Troy Street at about 17 feet; provides about 14 feet clear. Each of the parking levels is effectively‘flat’ with the speed ramps at the south end providing vertical circulation.

The two at grade parking areas below the supportedlevel function like two independent surface parkinglots. It is necessary to exit these ’lots’ in order to access the upper levels of the structure. The onlyaccess point is located off of Saratoga Street. Thisoption also requires the acquisition of the adjacentresidential property.

Circulation is again a two-way traffic flow with 9’-0” wide spaces set at 90º to thetraffic flow. The concept structure has four parking levels with three of the levelssupported. Approximately 413 spaces are shown in the structure. Displaced are 132 spaces resulting in a net gain of about 281 spaces.

A single stair / elevator tower is shown in the northeast corner of the structure. Asecond stair tower is located along the west side of the structure.


7

Site 2 - Option 1

Site 2 is the existing municipal surface lot between the Library and City Hall. Three viable optionshave been developed for Site 2.

Option 1 is a single threaded helix design with theparking bays running parallel with Nine Mile Road.The parking structure is set back about 60 feetfrom the sidewalk, leaving most of the areabetween the structure and Nine Mile Road available for a free-standing building or a civicplaza. The main entry /exit portal is shown alongNine Mile Road, although the entry / exit couldalso be located along Troy Street.

Each bay of the parking structure is sloped upwards about 5’- 6” providing afloor to floor height of about 11 feet. Five supported levels are needed to provide 341 spaces; 77 existing spaces are displaced for a net gain of 264 spaces. The floor of the uppermost level would be about 49 feet above grade.Circulation again is in a two-way traffic flow. Parking spaces are 9’-0” widespaces set at 90º to the drive aisle.

A stair and elevator tower is shown in the northwest corner of the structure, near the Library’s reconfigured entrance. A second stair tower is located at thesoutheast corner of the structure near City Hall.

Site 2 - Option 2

Option 2 is also a single threaded helixconfiguration but with three parking bays runningin the east-west direction. All of the parking baysare sloped. A short jump ramp in the western turning bay allows the floor of the first supported level along nine Mile road to be about 14 feet above grade, accommodating ground level retailspace within the footprint of the structure. The 9,937 S.F. grade level retail space fronting NineMile Road would have approximately 11 footceilings.

With four total levels, three supported, the structurecontains about 383 spaces, for a net gain of about 267 parking spaces.


8

Site 2 – Option 3

Option 3 is a below grade solution. The conceptual plans show parking at the surface level. However, the concept can be easilyadapted to have a building above the underground parking area. A civic plaza could also be constructed on the surface level.

The overall configuration consists of three bays.Because the length of the site is limited, the middle bay is a series of stacked speed rampsproviding vertical vehicular circulation. Thespeed ramps are too steep for parking spaces.The speed ramps are shown approximately 26 feet wide accommodating two-way traffic.Light wells are included along both sides of the speed ramp, bringing natural light down into the parking areas. The primary stairand elevator tower is located near the midpoint of the structure, equidistantbetween the Library and City Hall. Enclosing the stair and elevator tower in glass could make a significant architectural statement, enhance security, and aid theeffort to bring natural light down into the parking areas.

The surface level uses a two-way traffic circulation pattern with 9’-0” wideparking spaces set at 90º to the drive aisles. To help prevent crossing traffic andto reduce construction costs, the below grade parking bays are 57 feet wideand use one-way traffic flow. The parking spaces are set at a 75º angle.

The structure, including the surface level contains about 347 parking spaces. The existing surface lot contains 108 spaces, for a net gain of approximately 239parking spaces. If all of the surface area is used for another purpose, therewould be about 263 spaces in the structure. The net gain in spaces would dropto about 155 spaces, falling short of the target number of spaces. However,another level could be added to below grade levels.

COMPARISON OF OPTIONS

Table 1 summarizes the seven options. Capacities range from 337 spaces to 413spaces. Option 1 for Site 1A has the smallest capacity; Option 3 for Site 1B, whichspans across Troy Street, has the largest capacity. The net gain in spaces rangesfrom 233 spaces to about 281 spaces.

Because the size of the site limits the structure footprint, two of the options arerelatively tall. The relative elevation of the uppermost floor on Site 1A – Option 1 is about 57 feet above existing grade. Parapet walls and enclosures for stair /elevator towers would be higher. Site 2 – Option 2 also has a small footprintresulting in a similar relative height of about 55 feet.

Two of the options include ground level retail space, both fronting Nine MileRoad. In addition, Option 1 - Site 2 includes a footprint of about 10,000 thatcould be used for a free-standing building or a public plaza or park. A buildingcould also be constructed over Option 3 for Site 2, which is the undergroundoption.

The efficiency of the options, expressed in square feet per parking space, range from 321 to 387 per space. Efficiency is an important factor in parking structuredesign. As the efficiency increases the construction cost per space decreases.

POTENTIAL CONSTRUCTION COSTS

Table 2 presents conceptual construction cost estimates for the three options.Before premiums, we recommend using a base construction cost for an above grade parking structure in the Detroit area of approximately $50 per square foot.Furthermore, we recommend using a construction cost of $120 per square footfor the underground option. The costs to enclose and shell out the retail space are estimated at $60 per square foot.

The estimated costs are for budgeting purposes; the actual cost will varydepending on the level of architectural detail and other features chosen.Excluded from the construction cost estimate are soft costs beyond design fees and testing, unforeseen below grade conditions such as environmentalremediation or unstable soils, significant rock removal and significant utilityrelocation.

OPERATING AND MAINTENANCE COSTS

Table 3 presents typical annual Operating & Maintenance (O&M) costs for an un-cashiered parking structure. The additional labor costs associated with for an operating scenario using cashiers can be extensive.

The base annual O&M costs total $242 per space. Utility costs for a below gradestructure are higher to operate ventilation fans and for longer operating hours for lights. The O&M costs also include a recommended $50 per space annual contribution to a reserve fund for long term structural maintenance.

The annual O&M costs range from about $82,000 for the smallest structure toalmost $100,000 for the largest.

MAINTENANCE REQUIREMENTS

Typically, a parking structure is designed with a service life of 50 to 60 years. During this service life major structural repairs should not be required (i.e. significant concrete corrosion deterioration repair,concrete topping replacement, concrete overlays, etc.). To achievethis service life, the following minimum housekeeping and maintenancewould be necessary.

1. Housekeeping is defined as work conducted by in-house staffconsisting of basic cleaning, sweeping, slab wash downs, etc.Housekeeping includes items such as:

� Sweeping of the stairs, elevator lobbies and floor slabs on aregular basis.

� Trash collection on a periodic basis.� Slab wash downs and floor drain cleanout on a semi-annual

basis.� Cleaning of stair enclosures, doors, door frames and glass on

a periodic basis.� Cleaning of signage, elevator floors, doors, walls, parking

equipment, etc. on a periodic basis.

2. General Maintenance – General maintenance would usually beperformed by in-house staff; however, outside contractors may berequired in some cases. General systems and componentsmaintenance typically include items such as:� Doors and Hardware – Periodic lubrication.� Elevator – Regular maintenance as suggested by

manufacturer.� Lighting – It is anticipated that the lamps should be replaced

every 2 to 3 years, and light fixtures will likely requirereplacement every 20 years.

� Sealants/Expansion Joint – Repair/replacement of isolatedsealant or expansion joint failure. Leaking at slab cracks mayalso require sealant installation.

� Painting – Touchup painting should generally be performed as damage is observed. It is anticipated that repainting ofexposed steel would be performed every 10 years, and parking stripes reapplied every 5 years.

3. Structural Maintenance – Structural maintenance is generally performed by outside contractors and consists of repairingdamage to waterproofing or structural elements. Structuralmaintenance would include items such as:� Crack and Joint Sealants – It is anticipated that sealants will

be replaced every 10 years.


13

� Expansion Joints – Expansion joints require replacement every 10 years.

� Stair/Elevator Tower Roofing Systems – These waterproofingsystems will likely require replacement every 20 years.

� Slab Penetrating Sealer – It is anticipated that a penetratingsealer would require reapplication every 5 to 10 years,depending on the type of material used.

� Concrete Repairs – It is anticipated that, even with state-of-the-art durability features, isolated concrete repairs will be required, generally due to corrosion deterioration.


14

SUMMARY OF OPTIONS

� Sites 1A, 1B, and 1C individually have site dimensions that are not conduciveto the development of a parking structure. A parking structure developed onSite 1A would need to be relatively tall, in relation to the surroundingbuildings, to reach the target goal of 200 to 250 additional parking spaces.

� A more feasible parking structure can be developed on a combination of Sites 1A and 1B. However, a structure on these two sites requires the closing,or spanning, of Troy Street. Closing a street in a commercial area should always be carefully considered. The closing of Troy Street would affectemergency access, and both vehicular and pedestrian access to and from Woodward Avenue.

� Spanning Troy Street with a parking structure requires that Site 1C be included. In addition, an additional residential property would be required.A structure spanning Troy Street would be relatively expensive and raiseurban design concerns.

� Site 2 has larger dimensions than the other individual sites. The two-baydesign, Option 1, leaves a space approximately 60 feet deep fronting NineMile Road that could be used as a freestanding development site or as a civic plaza / park. The three-bay design, Option 2, provides more parkingspaces in a structure with one less level. This option also includesapproximately 9,900 square feet of ground level retail space facing Nine MileRoad.

� The below grade solution (Option 3) is the most expensive of all the options.However, placing the parking area below grade frees the surface area for development of building and / or a civic plaza.

RECOMMENDED OPTION

The City of Ferndale formed a committee to participate in this design feasibilitystudy. Following the development of the Options, a draft version of this reportwas distributed to the committee for advance review. A meeting was then held to present and discuss the Options. The committee discussed the Options andsummary points presented above. The committee reached a consensus that Site 2 – Option 2 is the best choice for a parking structure. The selected Optionprovides parking serving both the City and the Library. The site is close enough to benefit the businesses along Woodward Avenue. In addition, it is anticipatedthat the presence of the parking structure can stimulate additional commercialdevelopment along Nine Mile Road.
