1 City of Manassas Park Proposed Stormwater Management Funding October 5, 2010

2 State and Federal Storm Water Mandates The State mandates implementation of ordinance, programs, and practices to meet storm water quality and quantity standards. The City is permitted by the State to discharge storm water from the Municipal Separate Storm Sewer System (MS4) to surface waters of the Commonwealth Structures that collect and direct storm water Streets, curb & gutter, ditches, pipes, driveways, sidewalks, inlets, ponds are included in the permit. No existing State or Federal funding is currently allocated to meet all mandated requirements.

3 Required Storm Water Plan Components Public education and outreach Public involvement/participation Illicit discharge detection and elimination Construction site runoff control Post construction storm water management (enforcement) Pollution prevention, maintenance, and monitoring of municipal facilities

4 Pollution Prevention, Maintenance, Monitoring Develop, implement and enforce The City is directly responsible for all violations of the MS4 permit and must provide stringent enforcement. Reduce discharge of pollutants to the Maximum Extent Possible (MEP) Protect water quality Ensure compliance with water quality standards Satisfy Clean Water Act, Virginia Stormwater Management Act and regulations

5 Fee Initiative City staff and engineers began a study of the condition, funding sources, and fee structure in Staff and the Governing Body have reviewed numerous options and iterations Goals Address program mandates with minimal impact to citizens. Utilize existing Public Works staff and budget as much as possible / appropriate. Prioritize poor/fair/good, ensure function, rebuild as necessary. Comply with Best Management Practices (BMP s) to meet EPA and State requirements cost effectively. Review fees in other jurisdictions

6 Lower Cost Plan Components Some plan components absorbed into Public Works O&M Budget Vegetation removal Public Involvement/Participation Construction site inspections Enforcement of EPA storm water requirements Annual maintenance

7 Unfunded Cost Components Renovation and/or repair of storm water facilities Ponds / Underground storm water structures Storm Water Pipes and Catch Basins (curbside storm water collection) Stream maintenance Minimize annual costs Ideally - all ponds would be renovated under one contract Reality minimize costs by addressing, correcting basic functions, and implementing phasing to ensure compliance. Evaluate annually the program cost, effectiveness, and compliance to ensure progressive improvement at lowest cost.

8 Storm Infrastructure

9 City s Storm Water Facilities TOTAL Estimated Costs Infrastructure Renovation (priorities will be reevaluated annually) $2,330,000 estimated for all work in today s $ s. Catch basins / storm water pipes, streams, underground structures - $500,000 Storm water ponds - $1,800,000 Other - $27,000 Annual maintenance to sustain function and minimize degradation - $100,000 / year

10 Annual Cost Estimate Staff reassessed annual cost to the minimum required to meet requirements for City s approved plan. Pay as we go and concentrate on worst first. Reassess facility condition and plan requirements annually

11 FY11 cost of $242,000 Minimum Costs Repairs on ponds rated poor and fair : $110,000 Maintenance, materials and labor for all storm water facilities (catch basins, stormwater pipe): $100,000 Public Outreach, Coop with other Northern Virginia jurisdictions: $10,000 Administrative Activities: $22,000

12 Fee Calculations Based on Total Impervious Area Total impervious area includes roadways and individual parcels within the City Impervious areas are surfaces that have been covered by any material that impedes the infiltration of water into the soils.

13 Determination of Total Impervious Area Impervious areas were calculated utilizing aerial photographs, site plans, and plans of record. Determine total impervious area throughout the City. Establish the square footage to represent 1 ERU Equivalent Residential Unit (ERU) = 2500 sq. ft. Based on actual impervious square footage of 70% of SFH Determine minimum annual cost to meet requirements of mandate Using area for 1 ERU, establish the number of ERU s in the City based on total impervious area in the City

14 Methodology Fee Calculation Apply methodology consistent with Prince William County and Loudoun County to determine ERU multipliers for different classifications of property Provides a means to fairly distribute fees among different classifications of properties Multipliers are applied against the fee associated with 1 ERU For example, a single family residence has a multiplier of 1, Townhouses/Condos have a multiplier of 0.75, and Industrial/Commercial developed property would be based on a case by case basis.

15 Proposed Manassas Park Rate Parcel Type Single Family Residence # of ERU s Annual Fee / ERU 1 $35.58 Townhouse/Condo 0.75 $25.82 Comment Commercial 1 to 182 $ $6, Average of $ Annually

16 Comparison of Stormwater Utility Fees Locality Annual Residential Rate Norfolk $96.96 Chesapeake $76.20 Va. Beach $72.36 Portsmouth $66.00 Suffolk $62.88 Newport News $58.20 Hampton $55.20 Prince William County $26.40 Alexandria (Several options under consideration) $48.00 Staunton $74.40 Fairfax County ** (based on $250,000 home at 1.5 per $100 of real estate value) $37.50 Average of VA Localities $61.28 Manassas Park, Proposed $35.58

17 Billing Semi-Annually with Real Estate Tax bill Single Family - $17.79 Townhouse/Condo - $12.91 Commercial - $17.79 to $3,237.94

18 Staff Recommendation Adopt Storm Water Management Program and Ordinance as presented.
