Abstract:
Hogtown Creek, located in Gainesville, Florida is severely impacted by the effects of stormwater runoff, including erosion, excess sedimentation, and water pollution. The Restoring Hogtown project examines two ways to combat these issues: the use of green infrastructure and better public awareness of water quality issues. The watershed of the entire creek was analyzed using GIS to select smaller scale sites along the creek on which to focus on detailed designs. Two sites were chosen and then analyzed on a smaller scale to understand their differences and context. These two sites were then brought to the conceptual design phase in which three concepts were developed for each one. Concepts varied in the intensity of development ranging from highly constructed to naturalized. One concept for each site was then chosen to bring to the design development level. The two final designs, the Peri-Urban Promenade and the Green Infrastructure Showcase, are intended to make stormwater issues visible and memorable in order to increase public awareness of the creek and the challenges it faces while it makes its way back to the Florida aquifer.

Human focused infrastructure at the site will include an upper promenade walkway and a lower exploratory walkway closer to the creek level. This design can accommodate the peak rate of Other features of this site include stormwater themed furnishings, a natural childrens playground, observation decks and overlooks, and light displays under the bridges to provide safety and interest as the path goes below. The Green Infrastructure Showcase design intends to bring attention to stormwater issues and creek health in a unique and bold way. The designs utilize settling ponds and native vegetation to perform the mitigation techniques while concrete and unique forms attract attention and bring awareness to the plight of Hogtown Creek. Placing these constructed works in a natural setting helps to increase their impact. These designs are also intended to encourage people to interact with and better understand and appreciate the creek. These diverse interventions, while Creek in this city park, could be adjusted streams.Natural creek enters treatment sedimentation pond allows particulate matter to settle grate viewing platform at original creek water level Natural creek to next treatment area down the creek with aquatic vegetation for biological uptake and further settling.

mods:abstract displayLabel Abstract Hogtown Creek, located in Gainesville, Florida is severely impacted by the effects of stormwater runoff, including erosion, excess sedimentation, and water pollution. The Restoring Hogtown project examines two ways to combat these issues: the use of green infrastructure and better public awareness of water quality issues. The watershed of the entire creek was analyzed using GIS to select smaller scale sites along the creek on which to focus on detailed designs. Two sites were chosen and then analyzed on a smaller scale to understand their differences and context. These two sites were then brought to the conceptual design phase in which three concepts were developed for each one. Concepts varied in the intensity of development ranging from highly constructed to naturalized. One concept for each site was then chosen to bring to the design development level. The two final designs, the Peri-Urban Promenade and the Green Infrastructure Showcase, are intended to make stormwater issues visible and memorable in order to increase public awareness of the creek and the challenges it faces while it makes its way back to the Florida aquifer.

10Introduction State Context deciding on a topic that would interest me for these past two semesters and that would allow me to research and design for these two aspects. When a studio-mate offered something I was interested in. Hogtown Creek is located in Gainesville which is the county seat of Alachua County in north central Florida. It is fed by many smaller streams and tributaries and its watershed is about 20 square miles. development and largely forgotten by the citizens of Gainesville. Before the years such instance in 1967 being called the The Great Hogtown Creek Massacre. Today every person who lives within its watershed. This quiet destruction is hard to combat and is not well understood by the general public. Hogtown Creeks greatest problem comes

Hogtown Creek and most of the creeks in Gainesville are unique to north Florida most of their water from groundwater seepage and small springs. I have brought many friends and visitors to Hogtown Creek and they are always amazed by how different it dire need of our attention and respect. Major IssuesStorm water runoff causing and pollutant discharge into the stream and aquifer. Lack of public awareness and appreciation for Hogtown and other creeks in Gainesville. Lack of public understanding that everyday actions and lifestyles lead to degraded water quality and can contaminate drinking water sources. 1 2 3Erosion Sedimentation PollutantsStormwater Runoff Lack of Public AwarenessPoor Water Quality Contaminated Drinking Water Lack of Appreciation for a Natural Resource Project Main Points Focus on the mitigation of sedimentation and pollutants from stormwater runoff to improve the environmental health of Hogtown Creek. Study the water quality of the entirety of the stream by analyzing previously conducted environmental studies and available GIS data sets. Design green infrastructure for key areas along the creek to suggest creative and artistic solutions for dealing with sedimentation and pollution. The creative design of the mitigation strategies is intended to make stormwater issues visible in order to increase public awareness of the creeks water quality and recreational opportunities.

13 Project Main Points of sedimentation and pollutants from stormwater runoff to improve water quality of the entirety of the stream and the general health of the ecosystems in and around it. This will be done by analyzing previously conducted environmental studies and available GIS data sets. Water quality issues will be addressed in regards to stormwater runoff and what can be done to mitigate the harmful effects from associated sediment and pollutants. Detailed design will be provided for key areas along the creek to suggest creative and artistic solutions for dealing with sedimentation and pollution. The creative design of the mitigation strategies is intended to make stormwater issues visible in order to increase public awareness of the creeks water quality and recreational opportunities. The methodology proposed for addressing solving these issues Researching case studies that deal with similar challenges faced by Hogtown Creek and applying the methods used for restoration to this local example. Researching green infrastructure systems that remove harmful pollutants from runoff and decrease erosion and sedimentation along the creek for green infrastructure installation. After the two or three best and unique locations have been highlight the creek and bring awareness of its predicament to inhabitants of Gainesville.Executive Summary

The watershed of the entire creek was analyzed using GIS to select smaller scale sites along the creek on which to focus on detailed designs. Two sites were chosen and then analyzed on a smaller scale to understand their differences and context. These two sites were then brought to the conceptual design phase in which three concepts were developed for each one. Concepts varied in the intensity of development ranging from highly constructed to naturalized. development level. visible and memorable in order to increase public awareness of the creek and the challenges it faces while it makes its way back to the Florida aquifer.

16Background and History Hogtown Creek is located within Gainesvilles northwest and southwest quadrants. Its watershed is relatively large and includes about 20 square miles. Hogtown Creek has several tributaries that extreme erosion and sedimentation. The creek bed is mainly sandy with very little aquatic vegetation which is natural for seepage streams due to their location within thick canopy forests. The creek also cuts in many places is often no higher than ankle depth on an adult. The drainage ditch.Physical Site Features

18 a generally southwest direction until it reaches Haile Sink. It is met by multiple tributaries coming from all different directions in Gainesville. The creek goes through mainly residential areas and parks but is from commercial uses. Gainesvilles creeks are very popular locations for exploring and fossil hunting. It is a well known fact that fossilized sharks teeth can be easily found in the sediment of Hogtown Creek within a short while of searching. While this practice may not be in the best interest children and adults alike. The loss of water quality of these creeks is devastating to this cultural activity as it prevents entry into the creek and will eventually lead to no relationship between people and the creeks of Gainesville.

Several issues became apparent at the 34th Street and and analysis. Two sediment traps are located in the creek and were part of past efforts to reduce the amount of sediment that hits Haile Sink. My design calls for the removal of both of these and replaces them with a more natural creek and plant uptake system. The existence of an erosion wall at the bend in the creek was also noted as well as the presence of wading birds.

The peri-urban promenade on Hogtown Creek at popular public space for Gainesville. using a terrace system to prevent erosion. The sinuous nature of the creek will slow down the water and allow for more settling of sediment and debris. The edges of the creek will be replanted with native wetland and littoral species which will improve water quality through biological uptake of excess nutrients and also provide habitat for multiple animal species. More species present in and around the creek will improve the overall health of the stream. Different planting zones will be established throughout the levels of terraces changing trees will also be planted and allowed to mature over time as they go through the stages of succession. The reforestation of the creek banks will create additional habitat and may serve as an ecological corridor from Loblolly Woods to Hogtown Creek Woods. The already existing underpasses will be utilized for this purpose as well. focused infrastructure will be put into place. This will include two levels childrens learning playground. The two walkways are comprised of the main 10 wide paved promenade at street level and an 8 wide exploratory walkway closer park and view the creek even when it is running full after extreme rain events. This will allow the public to see the effects and realities of urban stormwater and further promote the awareness of these issues. The lower walkway will be accessible most of the time as it has been recorded and resume its function when water levels drop again. This lower walkway is designed to allow pedestrians to be close to the The Peri-Urban Promenade

Its design is intended to be a slower experience than the upper promenade and it encourages this by being sinuous in shape; The promenade intersects two bridges along this section of path continues under the bridge. The two paths split after emerging design calls for vibrant light displays to be put in place to make the promenade accessible at all times of day and make the underpasses an attraction rather than a place to avoid. that are reclaimed water pipes or unused concrete sewer pipes. local families to experience the creek and promenade. Located playground would have adventure and nature based play as well as interpretive signage and activities based on the creek and promoting awareness to children and families. This linear park and promenade will be accessible from several Loblolly Woods trails to the north east. Both the promenade and the exploratory walkway will be fully ADA accessible with creative ramps and wider walkways. around this site will be converted into new multiuse areas. If that as a pedestrian friendly circulation system through this part of town. It could also expand past its current borders and include outdoor dining and other spaces connected to restaurants and businesses that wanted to take advantage of improved creek views. If the promenade were truly developed and the creek restored renewed interest in bettering and redeveloping this part of Gainesville.

I began the calculations by collecting data about the the creek flow was recorded to have a base flow of 18.59 cubic feet per second(cfs). Its minimum flow was a meager 0.06 cfs. It peaked in flow during this time at 860.00 cfs. In seems that this peak flow would have occurred during or right after the series of storms in 2005 that made it a record breaking hurricane season. This seemed very likely to be about the highest peak flow Hogtown Creek would see in a long period of time. created an abstracted framework drawing in AutoCAD to use for determining the depth of the water at different flows rates. It was determined that a peak flow rate with the current creek then created the desired creek section in AutoCAD using a terracing approach to prevent erosion while still conveying the same amount of flow. The proposed creek section would Hogtown Creek overall. The next few pages contain all the calculations and accompanying charts and graphs to support these findings.Creek Flow Calculations

The Green Infrastructure Showcase design intends to bring attention to stormwater issues and creek health in a unique and bold way. The designs utilize settling ponds and native vegetation to perform the mitigation techniques while concrete and unique forms attract attention and bring awareness to the plight of Hogtown Creek. Placing these constructed works in a natural setting helps to increase their impact. These designs are also intended to encourage people to interact with and better understand creek and other streams.

The design calls for a social stairway to be installed leading from the boardwalk to the creek. The stairs provide both a seating and gathering space as well as access to the lower viewing area. An ADA accessible ramp is also worked into the design. STAIRS CHARACTER IMAGERY

The creek that slows the water and allows for larger sediments to sink to the bottom. The creek then enters a vegetated basin with native wetland and the water further. The creek then exits the basin series and continues on.

It also serves as an amphitheater and casual seating area for all visitors to the creek. The top tier of one side of the amphitheater is ADA accessible to provide access to all.

108Conclusion and Further Opportunities I have come to understand more about the complications that we face when it comes to improving water quality. It is a far larger concern to all people. In proposing these designs and interventions a huge difference in the problem at hand. I only hope that increasing public awareness of the creek and its challenges could help people to better value it and understand how to take care of it. I also hope that implementing these green infrastructure techniques at multiple places along the creek could play at least a small part in improving an awareness campaign to accompany the actual design portion. environmental art and water quality campaign materials aimed at and further its goals. target the behavior and infrastructure that causes it in order to have any lasting positive effects. I hope that all residents of Gainesville will soon come to understand and appreciate this beautiful creek. I hope they will realize it is worth all the effort to protect and preserve know it.
