Senior Design 50% Completion Report
The purpose of this report is to describe the project progression regarding the
Senior Design Project: Stewart Road Park. The park is located in the Dauphin Island
Parkway Vicinity, shown below.
Figure 1: Vicinity Map
Figure 2: City Map
As shown, the park is in a very residential area, which could potentially bring a large
amount of traffic into the park with the right improvements. Currently, the park is in
poor condition with little to no attraction for visitation. The Parks and Recreation
Department has requested the removal of all existing features with a clean slate to
redevelop. The existing overhead layout of the park is shown below.
Figure 3: Existing Conditions
The design team has decided to divide the project into 6 prioritized phases. This will
allow the City of Mobile to choose alternative design processes, priorities, and
timelines. As of now, the Design Project is at approximate 50% completion. The
team has selected alternatives for each phase, created layouts, estimated quantities,
and has begun preliminary design.
With alternatives selected, and the team has decided on implementation and
location, the design process is ready to continue. This will include all necessary code
requirements, computations, cost analysis, creation of design files, and any other
necessary material for design. The current
As mentioned, the design project has been divided into 6 phases. These phases
include:
Walking Path
Recreation Improvements
Parking Lot
Pavilion Improvements
Drainage Plan/Stream Restoration
Utility Improvements (Public Restroom and Water Fountain)
Each phase is self-inclusive, and is independent of phases. This allows the City to
pick and choose desirable phases if the budget does not allow for complete redesign.
It also allows for a lengthy timeline, which was mentioned as a desirable trait by the
Parks and Recreation department. The project phases, listed and described, are as
follows:
Phase 1: Walking Path
This phase includes complete design of a concrete walking trail throughout the park.
This will be a strong attribute to the park. Being in a residential location, walking
paths are a major interest in family activity. The walkway will include ADA
compliant ramps. The design of the walking path will allow for positive drainage
towards the existing stream, which carries the water to Perch Creek.
The selected path alternative for the walking path will include a path that connects
two 20-foot-long walking bridges in a looped system. The path will be 1,130 feet in
length and will require a rough amount of 85 cubic yards of concrete. The selected
path alternative will allow for ADA compliant connections to each newly proposed
feature.
The path will be made of concrete in its entirety, rather than partial concrete and
gravel. The design will be ADA compliant and will allow every visitor to access its
entire layout. The layout of the walking path can be found attached.

Phase 2: Recreational Improvements
Currently, there exists one basketball court, and two swing sets. The Parks and
Recreation Department has requested complete removal of the existing recreational
features. However, a new basketball court is stressed to be a major feature that must
be implemented because of the value it holds to bring in visitors.
The team will implement all recreational improvements into one phase.
Improvements include:
● Volleyball Court
● Basketball Court
The team is confident that these two implementations will prove to be a positive
improvement to the park. The volleyball court will be a full 6 on 6 person court with
dimensions of 29’ by 59’. The sand chosen to be implemented was a special mix sand
from VolleyballUSA.com. It prevents the players from receiving cuts, as well as the
sand not being a dusty material. Due to the decision of installing a full volleyball
court, it will require about 200 tons of sand one to two feet deep. The selected
recreational net was chosen because of the durability and strength it contains,
which is why it is one of the most popular versions of an outdoor net. The
permanent fixed volleyball poles were selected as the match to the recreational net
in order to properly sustain it.
The basketball court will be a full court with dimensions of 95’ by 50’ and an area of
4,750 sq. ft. It will be poured with plain concrete because of its cheaper price per sq.
footage. In addition, two aluminum backboards along with two metal chain nets will
be incorporated considering they are extremely durable and a less expensive type.
Both the basketball and volleyball court alternatives were chosen with maintenance,
cost, and sustainability in mind. AFAR Consulting believes the materials chosen will
be the most efficient choice for installation. The layout of both recreational
improvements are shown below.

Phase 3: Parking Lot Design
Currently, the park has no parking implemented. There is a small, dirt turn-in that
leads into the park, but doesn’t lead to any parking. A small parking lot will be
designed designated towards the accommodation of ADA compliance, maintenance,
and positive drainage towards the existing stream. The lot will be relatively small,
located in the front of the park. The lot will be designed to connect to the walking
path with ADA compliant ramps, and will contain the standard number of handicap
spaces.
The selected alternative for the parking lot is a complete asphalt lot with 14 parking
spaces (2 handicap spaces), and overland drainage directed towards the stream.
This design will call for approximately 75 tons of asphalt. This option will facilitate
handicapped access to the walking path and other newly proposed features, reduce
the possibility of a flooding in the parking lot and helps reduce the maintenance cost
of Stewart Park. The proposed parking lot location, shown below, will be near the
entrance of the park.

Phase 4: Pavilion Design
The park currently contains an existing gazebo, which shall be removed per request
of the City. The existing gazebo is in poor condition shown in the figure attached,
and appears to have some rotting.
Figure 7: Existing Gazebo
This gazebo will be replaced with a new pavilion. The new pavilion will be greater in
size, much more aesthetically pleasing, and ADA compliant with connection to the
walking path.
Figure 8: Proposed Pavilion
The selected alternative is a 24’x44’ wood-gabled pavilion. The pavilion is
prefabricated, delivered, and installed on an existing slab. The slab will be
approximately 120 Sq. Yd. of 4” thick concrete. The pavilion shall be located as
shown.
Figure 9: Pavilion Layout
Phase 5: Stream Restoration and Drainage Improvements
Currently, there are several locations on the south side of the park that either hold
water or direct water away from the existing stream. The attached figure shows the
topographic map, as well as the existing stream.
Figure 10: Topographic Map
As shown, the park currently has an existing stream that runs the complete vertical
length of the park, located on the west side. The stream connects to an existing
culvert, which runs underneath the roadway, and continues to travel to Perch Creek.
The stream has erosion issues, and the bank is noticeably washed out. See the
attached figure for an example of the eroded ditch.
Figure 11: Ditch Erosion
The selected alternative includes the regrading the south part of the park and
creating a grassed swale. This will account for the pooling water, as well as the
newly formed runoff that will accumulate due to the asphalt parking lot. This
alternative also includes stream restoration. Restoration of the stream will include
widening of the stream in several eroded locations, building up the bank with select
fill, lining the top of the bank with geotextile materials, and a step-pool design to line
the ditch with rock. The proposed layout for drainage improvements are attached.
Figure 12: Drainage Layout
Phase 6: Utility Improvements
Currently, there is no access to public utilities. Existing sewer/water lines are
located in public right-of-way. The team will utilize these resources to design the
proposed improvements. Improvements include design of a public restroom and a
public water fountain. The team is confident that these implementations will prove
to be a positive improvement to the park. The alternative selected includes an inhouse design for both improvements. The proposed layout and preliminary design
detailing are attached.
Figure 13: Restroom Layout
Figure 14: Preliminary Design Detailing
The team selected the in-house design for several reasons. Design will be more cost
effective, there is more freedom in material selection, and one contractor will be
able to complete all of the utility work. With the prefabricated design, there would
be two separate entities involved, doubling up on mobilization fees, installation,
labor, etc.
In addition to a prefabricated vs. in-house alternative, the team had to decide on
material alternatives. This was mostly a decision between brick and concrete
walling, stainless steel vs. porcelain toilet/sink features, and concrete vs. tile
flooring. After calculating areas, volumes, and cost comparisons, the team decided
on the following materials:
Concrete Flooring
Concrete Walling
Stainless Steel Toilets and Sinks
Shingled Roof System
Wood Rafter Support System
AFAR Consulting is now preparing to move towards a 75% completion submittal.
This will include cost evaluation of each phase and conceptual design completion
(calculations and detailed drawings). If the Parks and Recreation Department decide
to implement all 6 Design Phases, the overall layout of the park will roughly look
like the figure shown below.
