Viable models for dedicated, on-going clean water funding The state and many local governments are ramping up investments in clean water. In 2012, the State of Maryland doubled the Bay Restoration Fee, raising an additional $50 million in revenues to be redeployed to local government infrastructure around the state. That same year, stormwater utility fees became mandatory for Maryland’s 10 largest counties, raising an additional $100 million
Clean water funding can take a variety of forms. The most effective approaches have dedicated revenue streams. Stormwater/surface water utilities: City of Salisbury Town of Oxford Town of Berlin Renewable capital funding: Queen Anne’s County Wicomico County ACTION NEEDED: Talbot County’s clean water efforts are hampered by a lack of recurring local investment. CBF encourages the County Council to evaluate and select a long-term funding strategy that includes local revenue.

WHAT: Better stormwater management practices for new growth
Newly hardened surfaces and higher wastewater flows can increase pollution loads to local waters and the Chesapeake Bay. In 2008, the state adopted new regulations for stormwater management that prioritize Environmental Site Design (ESD). The infiltration practices installed at Waterside Village are good examples of how ESD promotes the use of natural drainage patterns and “green infrastructure” to protect water quality.
WHY: Mitigates pollution due to growth
Traditional practices, such as curb and gutter or large holding ponds, often focused on centralized collection and treatment of stormwater. ESD retains the benefits of this “gray infrastructure” while more effectively slowing and filtering nutrient and sediment pollution. Even with the 2008 regulations, new development has the potential to increase polluted runoff by
additional load will be added to state and local reduction targets, increasing the effort and cost of achieving clean water goals by as much as 20%. The state has drafted an Accounting for Growth policy that would ensure that new loads from growth are properly offset; however, these regulations have not yet been adopted. Sector: Polluted Runoff Strategy: Minimize new loads
WHAT: Retrofit of existing impervious surface
Previously a private, fenced valet lot that allowed for double parking of vehicles, the Town of Easton needed to reconfigure the parking spaces to allow normal parking, pursuant to accepted Town of Easton Planning and Zoning parking lot standards. Additionally, the lot and sidewalks needed updating to meet ADA requirements. In every planned configuration there was excess or non-usable space remaining. While not required by state regulations, the Town used the extra space for an
replaced soil with a suitable mix, and planted the site with compatible trees and
recharge and water quality improvements, in addition to beautifying the streetscape.
WHY: Leverage pre-programmed work to reduce costs
Facing a design challenge, the Town of Easton identified this project as an
estimates value of the work completed to construct the stormwater facility at approximately $10,000. Sector: Polluted Runoff Strategy: Municipal action
WHAT & WHY: Comprehensive approach & partnership to restore an urban watershed
The Town of Easton and Talbot County have partnered to make substantial improvements to Tanyard Branch, an urban stream flowing through the heart of Easton. In 2010, a state Trust Fund grant provided funding to construct more than 2 acres of ponds and wetlands located at a natural low point near an existing storm drain collection system. In 2014, funds were leveraged from the Governor’s Stream Restoration Challenge to plant 13 acres of riparian buffer along the north edge of the facility and install a 600 square-foot floating wetland in the pond. The total state investment in this work stands at about $829,000. These projects demonstrate that partnership between Talbot County, its towns, and citizens is a successful formula to leverage outside funding and make substantial progress towards goals to reduce polluted runoff. Sector: Polluted Runoff Strategy: Municipal action
WHAT: Ditch retrofit pilot projects
Ditch retrofit projects include practices like shallow-water wetlands, grassed waterways, and two-stage ditches to treat polluted runoff from county roads and upland agricultural fields. Most projects involve excavation, re-grading, and planting of nitrogen-removing grasses and shrubs. Select projects will be actively monitored with in-field equipment to evaluate performance. Estimated construction costs and nutrient removal efficiencies are standardized to more easily assign credit for pollution reduction. Pilot projects featured in the following pages are funded by the state through The Nature Conservancy’s (TNC) Chesapeake Bay Trust Fund grant award, agricultural cost- share dollars, and Talbot County’s $50,000 FY14 capital appropriation.
WHY: Cost-effective pollution reduction
These pilot projects are examples of a targeted retrofit approach supported by county farmers, CBF, TNC and the Talbot County Department of Public Works. This approach uses a tool that analyzes elevation, land cover, and other data to identify locations in the county’s roadside ditch network that could deliver the biggest return on investment in restoration. Collectively, the highest-performing 150 sites are expected to reduce approximately 8,000 pounds of nitrogen pollution – 17% of the county’s total nitrogen reduction goal for polluted runoff – at prices nearly 90% less than other urban practices.
ACTION NEEDED: Dedicated local investment in ditch restoration

WHAT: Wetland creation and reforestation
Talbot County recently acquired an 86-acre property adjacent to the Town of Oxford to develop a passive public park. As part of the first phase
sediment loads from both the existing site and the adjoining agricultural land. The project presents an excellent opportunity to raise awareness and educate the public on various management practices being used to reduce pollution to the creeks and the Chesapeake Bay.
WHY: Restoring natural systems to help water quality
Changes in the use of land from natural conditions to farms, towns and roads result in an increase in the amount of nutrients and sediments entering the waterways. The excess pollutant loads cause increases in algae, decreases in water clarity and loss
have a significant impact on aquatic life and the recreational uses of the nearby creeks and contribute to the decline in the health of the Chesapeake Bay. Many of the management practices demonstrated here will mimic natural systems to increase the quality of the water leaving the land.

Review efforts to reduce pollution from wastewater and septic systems, and consider a long-term pollution reduction strategy for Talbot County
WHAT: Upgraded systems and coordinated maintenance, including pump outs
Since 2009, Talbot County has received more than $4.5 million from the Bay Restoration Fund to equip septic systems with nitrogen removal technology. This activity is expected to continue, and could increase as additional funds from the BRF become available starting in FY 2018. To address maintenance, the Department of Public Works is developing a program to track pump-out
has proposed exploring the creation of a septic utility. A septic utility would help ensure that maintenance, pump-outs, and upgrades occur at necessary intervals.
WHY: Low cost, accelerated pollution reduction from septic systems
A household on a conventional septic system pollutes at a rate five to 10 times greater than a similar household connected to a wastewater treatment plant. Septic systems upgraded to Best Available Technology (BAT) cut the load in half. Regular inspection, maintenance and pump out can reduce nitrogen loads in some places by up to an additional 10%.
ACTION NEEDED: Coordinated septic maintenance program
A coordinated septic maintenance program could accelerate implementation, streamline management, and provide a reliable tracking and verification framework critical to maintaining credit for septic system maintenance. Similar actions have been taken in neighboring counties. Queen Anne’s County has adopted a mandatory pump-out requirement, and Dorchester County recently commissioned a study to evaluate the feasibility of a septage management district. Sector: Septic systems Strategy: Management
WHAT:
The Region V wastewater treatment plant serves a portion of Tilghman Island, discharging about 150,000 gallons per day into the Chesapeake Bay. The county is seeking grant and loan funding to upgrade the plant to current nutrient removal technology. MDE has identified the plant as a priority minor wastewater treatment plant to be upgraded; funding could be available as early as July 2015. The county is also reviewing sewer extensions to villages and environmentally sensitive areas. Talbot DPW is in the planning process and needs to complete applications for funding. DPW will conduct public meetings with citizens in areas where sewer will be extended, including a review potential infill development and out-of-pocket costs for residents. Needed policy work includes updates to the comprehensive plan, tier map, zoning ordinance, and the Comprehensive Water and Sewer Plan.
WHY:
Neither the Region V wastewater treatment plant, nor the majority of septic systems on Tilghman Island are equipped to remove nutrient pollution from wastewater. An upgrade to the Region V plant, combined with targeted sewer line extensions to areas of clustered septic systems, is projected to reduce 12,500 pounds of nitrogen pollution (more than half of the county’s 2017 goal for septics).
ACTION NEEDED: Updates to planning & infrastructure policy
Following the comprehensive plan update, the County Council will need to introduce an update of the Comprehensive Water and Sewer Plan identifying service areas and controls on new development, hold public hearing(s) on the draft, and adopt a plan for submission MDE for final approval. Sector: Septic systems Strategy: Sewer extension
