1 Watershed Management Program To Meet our MS4 Permit American Council of Engineering Companies/Maryland 2018 Spring Environmental Forum Tuesday, May 15, 2018

2 2 Montgomery County, MD 500 sq. miles, over 1 Million people Significant development occurred prior to modern day stormwater management requirements Over 1,500 miles of streams Two major river basins 184 spoken languages 2

3 3 Our Mission The Montgomery County Department of Environmental Protection (DEP) works to enhance the quality of life in our community by protecting and improving the County s air, water and land in a sustainable way while fostering smart growth, a thriving economy and healthy communities.

4 4 Our Water Quality Goals 1. Achieve stormwater treatment on 3778 impervious acres 2. Support local, regional and national efforts to protect water resources and the Chesapeake Bay 3. Engage public in water quality improvement practices

5 5 County s MS4 Permit Requires treatment of 20% of the runoff from impervious surfaces that is inadequately treated or untreated After calculation of the impervious acres (IA) in the County (25,119), an analysis of the Best Management Practices in place controlling IA to the Maximum Extent Practicable was calculated. This resulted in a goal of 3,778 IA needing to be treated The permit was issued in 2010 with a 5 year timeframe. As of the end of FY17-2,927 IA have been treated, 77% of the goal The County entered into a Consent Decree with Maryland Department of the Environment in April Required to complete the 20% restoration goal Complete a SEP Provide a schedule for practices that have not been inspected

6 6 County s MS4 Permit To meet the 20% restoration goal, there are a variety of BMPs under design including Stream Restoration Pond Retrofitting Green Infrastructure Green Streets Government Properties County takes credit for Alternative Practices Street Sweeping Septic disconnections/wwtp connections Tree Planting Data Improvement to account for New BMPs that treat existing impervious area

7 7 Funding The County s Water Quality Protection Charge (WQPC) provides adequate funding for the design and construction work The WQPC is issued to all residential and commercial property owners annually The County currently has 2 Bonds (2012 and 2016) to fund the construction. These generally fund design and construction of BMPs on public property The approved CIP program includes a program cost of $102M The WQPC also funds the staff, the operational expenses and the debt service on the bonds

8 8 Current Contracting Strategies for Watershed Restoration Work For design, 8 firms pre-qualified under contracts issued in Work is typically competitively awarded on low bid to these pre-qualified contractors. Final contract date of For construction, 8 contractors were pre-qualified under a contract issued in The contract term ends March, Work is competitively awarded on a low bid basis Invitation For Bid process has been used for project specific construction A unit price contract for LID projects expires in January 30, 2019 Several program support contracts are in place for program planning, engineering support, asset management tracking Two Pay for Performance Contracts for 3 projects were awarded in 2017 for turnkey delivery of treated IA no later than July, Design and Construction are included in the scope

9 9 Future Watershed Restoration Contracting The County is reviewing our contracting strategy to ensure we have the right vehicles in place to meet the demands Prequalified Design contracts end in several years. When new MS4 permit issued, additional IA may need to be restored. New contracts may be needed The pre-qualified construction contract expires in October Future contracting may include: Pay for Performance: Purchasing IA/pollutant load reduction Credits. This type of contract has advantages. Evaluating if it can be used for construction scope only to allow completion of projects already in design Evaluating Design-Build or Design-Build-Maintain contract scopes The County is working with other MS4 jurisdictions to evaluate opportunities for partnering.

10 10 Inspections and Maintenance Currently, there are 12,000 facilities in the Asset Management System Inspections on a triennial basis; Maintenance to ensure function of facilities; Follow-up inspections to ensure necessary repairs are complete; and Enforcement actions to ensure compliance. BMP Assets and their inspections and maintenance are tracked and scheduled through an asset management system Contractors must use the asset management system to be assigned work and report on its progress. The County provides training to awarded contractors. The system integrates inspection and maintenance work order tracking and allows DEP to compile data to meet permit requirements

11 11 Inspection Work Scope Total Number of Inspections Completed (FY17) Triennial Inspections 1,487 Annual Underground Pre-Maintenance Inspections 931 WQPC Credit Inspection 106 Unscheduled Inspections (transfer, complaint, maintenance) Total Number of Inspections Completed 10 2,534 Triennial Inspections Completed (FY17) Regions 3 and 1 Inspection Type Total Environmental Site Design 153 Filtering Systems 349 Stormwater Infiltrations 131 Oil/Grit Separators 180 Proprietary Hydrodynamic 4 Stormwater Ponds 11 Underground Storage 364 Stormwater Wetlands 0 Open Channel Systems 201 Other 94 Triennial Inspections Completed in FY17 1,487

12 12 Maintenance Work Scope FY17 Stormwater Facility Repairs and Maintenance Type of Facility Privately Owned and Maintained Total Aboveground 281 Underground 325 Number of Privately Owned Facilities Maintained by Owner 606 Number of Private Maintenance Compliance Inspections 666 DEP Maintained Aboveground Structurally Maintained 545 Routine Sand Filter Maintenance 25 Mowing and Trash Removal 13 Underground Structurally Maintained 718 ESD/ Low Impact Development (LID) Routine Maintenance 1,618 ESD/LID Facilities Repaired 19 Number of Facilities Maintained by DEP 2,938 Total Number of Facilities Maintained (by Owner and DEP) 3,544

13 13 Inspection and Maintenance Contracting The inspection work for aboveground and underground facilities is done under one contract. This contract expires in Seeking efficient methods of conducting rapid assessment of ESD practices Explosion of ESD practices in the County due to infill development The maintenance work is done under multiple contracts, generally by BMP type: Above ground one contract; expires in 2019 Underground one contract; expires in 2019 Use contracts for maintenance of green roofs, porous pavement, and dredging

14 14 Green Infrastructure Training and Certification DEP is interested in growing the workforce that are skilled and trained in maintenance of green infrastructure Partnering with WEF and other jurisdictions to sponsor National Green Infrastructure Certification (NGIC) Program. Exploring MOU with Montgomery College to continue education in Green infrastructure inspection, construction, and maintenance DEP's Stormwater Facility Maintenance Program relies on skilled and knowledgeable contractors to perform maintenance on stormwater management facilities. A company that performs maintenance on a stormwater management facility must hold a certificate of attendance from an approved training program

15 15 The County strives to promote a business environment to foster sustained business growth and job creation Two key programs have significant impact on contractors doing business with the County: Minority, Female, Disabled Program. As of July, 2015, the County includes MFD participation as evaluation criteria in solicitations Local Small Business Reserve Program Ensures the County departments award 20% of procurements for goods, services, and construction to registered and certified local, small businesses Register in the County s Central Vendor Registration System once registered you will receive notices when appropriate solicitations are issued by the County Contact DEP.Procurements@montgomerycountymd.gov for more information.

16 16 Discussion points Construction of BMPs With this understanding of the projected future work, are there questions or comments you are willing to share regarding bidding on future construction work? If you work in other jurisdictions, are there best practices you observe? What advice or input do you have for DEP as we go forward in refining our plans for meeting these IA treatment goals?

17 17 Discussion Points Inspection and Maintenance Does a strategy of having inspection and maintenance contracts set up based on BMP type make sense? Are there other strategies that should be considered? Are you a company or are you aware of companies that might be interested in growing their workforce skilled in maintenance of green infrastructure? How do you suggest we attract potential workers to be trained in green infrastructure? Do you have any advice on next steps as DEP considers a P3? What are the potential opportunities and challenges with a long term maintenance contract?
