Lilly Creek Improvement Project
What is Lilly Creek? Lilly Creek is an open-air, private stormwater drainage system which collects surface water from western Greene County and eastern Montgomery County emptying into the Mad River.
Lilly Creek Watershed Area Shellabarger Park Lilly Creek Watershed Boundary
What are the issues with Lilly Creek? Erosion of Creek Banks Material & Debris Build-up Specific Property Flooding
Why are there issues with Because Lilly Creek is a private storm drain, there has been no comprehensive maintenance plan and property owners have been able to make improvements on their property typically compounding erosion issues downstream Lilly Creek?
Recent History In late-summer 2008, the City received a petition from approximately 25 property owners on Bayside Dr & Barrett Dr asking the City to look into addressing the erosion issue caused by Lilly Creek
A request was made of City Engineers, LJB, to review a solution to the problems of Lilly Creek and provide a possible solution to the concerns presented by residents Recent History
Recent History On June 18, 2009; the City received a recommendation from LJB to provide for the installation of gabions along the Lilly Creek channel from Shellabarger Park to The Prairies
The proposed gabion solution would affect approximately 129 separate properties and create additional channel storage volume and bank stabilization. Recent History
Recent History In order to effect this solution, several items need to occur including the removal and replacement of several fences, sheds, and other personal property items as well as significant excavation for the placement of the gabions. Total Project Cost: $12.1 million
Recent History Based on the total costs associated with the project, consideration of all financial resources available to fund this project, and several other factors; this proposed solution was tabled in effort to find a more cost-conscience solution.
MCSWCD: A new partnership In early 2009, the City was introduced to the Montgomery County Soil & Water Conservancy District (MCSWCD) as an organization who might be able to assist the City in addressing Lilly Creek
MCSWCD: A new partnership Throughout 2009, the City met with MCSWCD, the Greene County Soil & Water Conservancy District, and their engineers at Malcolm Pirnie to discuss an alternative solution to the issues of Lilly Creek. These meetings have resulted in a viable solution
A Viable Solution This proposed solution is a threephased project which deals with water retention & detention and the restoration of existing creek banks in an environmentally friendly manner.
A Viable Solution The three phases of this project include: 1. Construction of a retention/detention pond in eastern Riverside 2. Cleaning of and bank stabilization of Lilly Creek 3. Construction of a retention/detention pond in western Greene County
A Viable Solution Phase I Construct a multitiered retention/detention pond along the northern end of Shellabarger Park
A Viable Solution Phase I Concept - Enables grant dollars to become available - Provides water retention - Designed for safety using bio-friendly methods - Adds new recreation opportunities
Part 2
A Viable Solution Phase II Pre-Phase II Clear debris and restore Lilly Creek banks from Shellabarger Park to the Prairies Post-Phase II Post-Phase II
A Viable Solution Phase III Future construction of a retention or detention pond in western Greene County.
A Viable Solution As part of this proposal: The City will become responsible for the maintenance of the Shellabarger Pond MCSWCD will acquire a public maintenance easements from property owners and assume long-term responsibility for Lilly Creek maintenance
A Viable Solution In order to effect Phase I & Phase II of this solution, several items need to occur including the construction of the detention pond in Shellabarger Park, the clearing of Lilly Creek, and the bank restabilization of Lilly Creek. Total Project Cost: $1.5 million
Moving Forward Based on the total costs associated with this solution, consideration of all financial resources available to fund this project, and several other factors; this proposal is being recommended for further consideration to you as property owners affected by Lilly Creek.
Lilly Creek Project Funding As proposed, the estimated cost to address the current Lilly Creek erosion issue is $1.5 million. The proposed funding for this project is a combination of federal/state grant dollars and special assessment.
Lilly Creek Project Funding Why a special assessment? A special assessment is recommended to fund this project because the cause and effect of the problem being addressed are geographically defined.
Lilly Creek Project Funding Who would be subject to special assessment? Option 1: All property owners in the City of Riverside & Greene County within the Lilly Creek Watershed Option 2: All property owners in the City of Riverside within the Lilly Creek Watershed
Lilly Creek Project Funding Option 1: All property owners in Montgomery & Greene Counties within the Lilly Creek Watershed Benefit: Would reduce assessed expenses by spreading cost to multiple parcels Drawback: Would delay project start and increase the required number of petitioners
Lilly Creek Project Funding Option 2: All property owners in the City of Riverside within the Lilly Creek Watershed Benefit: Would decrease the time to begin the project and decrease the required number of petitioners Drawback: Would increase assessed expenses
Lilly Creek Project Funding How would my special assessment be determined? Assessments are determined by adding all project costs and dividing that cost amongst all parcels of property in the assessment district as a percentage of each parcel s area within the district
Lilly Creek Project Funding How much would my special assessment be and for how long? That all depends.
Lilly Creek Project Funding What do I really get for paying my special assessment fee? 1) Elimination of the existing and on-going erosion issue 2) Elimination of creek maintenance responsibilities 3) Increase in property value for future resale
Lilly Creek What Next? In order to proceed with this project, you as residents of the Lilly Creek Watershed must petition the Montgomery County Soil & Water for assistance with this project.
Lilly Creek What Next? A valid petition will need to be signed by: 50.01% of the total number of property owners in the Lilly Creek Watershed 50.01% of the total property owners by area in the Lilly Creek Watershed
