CRI is currently acting as Maryland Department of Transportation State Highway Administration’s (MDOT SHA) Permit Manager for all its Chesapeake Bay Total Maximum Daily Load (TMDL) projects. The MDOT SHA is responsible for meeting the Chesapeake Bay TMDL through compliance with the requirements established in Maryland’s Watershed Implementation Plan for the Chesapeake Bay Total Maximum Daily Load (WIP). MDOT SHA maintains MS4 permit coverage for the MDOT SHA roadway in the 11 Maryland counties holding MS4 permits. As the Permit Manager, CRI is managing the coordination, wetland and waterway permit and forest conservation act permit package submittals, agency coordination and comment response, and monitoring plan development when necessary for over 11 tree plantings, 6 stormwater management retrofits, 2 new stormwater BMPs, 14 grass swales, and 15 stream restoration/outfall projects throughout the counties. CRI was hand-picked for this role due to the staff’s in-depth knowledge of natural resource permitting and MDOT SHA process, and excellent working relationship with regulatory agencies. Future tasks will include Managing the post construction monitoring effort of the stream restoration/outfall projects. Some specific project examples are detailed below:
TMDL Stream Restoration of Gramies Run, Cecil County, MD: The CRI Permit Manager is responsible for coordinating and obtaining all project environmental permits for this TMDL stream restoration project. The Gramies Run project site is a component of the Total Maximum Daily Load (TMDL) crediting program of the Maryland State Highway Administration Water Programs Division. The project involves the restoration construction of approximately 5,470 LF of Gramies Run and several tributaries, located between MD 273 (Telegraph Road) (North) and Russell Road (South). Responsibilities included: completing the Joint Federal State Permit Application Package for wetland and waterway impacts; completing the forest conservation exemption package; coordinating the project with the regulatory agencies, coordination with designers; request/coordinate support activities (stream/system studies, NEPA/MEPA, natural resource inventories); preparing the post construction monitoring plan; and obtaining environmental permit approvals.
TMDL Grass Swale, Anne Arundel County, MD: CRI conducted a desktop evaluation of this TMDL contract, which involves the construction of 44 grass swales within the medians along the MD 100 and MD 10 corridors to treat existing impervious surfaces and achieve pollutant load reductions and stormwater restoration. These facilities attenuate and treat stormwater runoff prior to entering the storm drain systems and waters of the US. The Permit Manager reviewed potential resource impacts intersecting limits of disturbance (LODs) of grass swale construction. GIS data of Maryland’s DNR & NWI wetlands, critical area, streams & rivers, 100 year floodplain, and forested areas were reviewed to determine potential resource impacts. The CRI Permit Manager provided a list of potential permits based on existing resources within the project area during preliminary and final design phases of the project.
TMDL Outfall, Cabin John Creek (Tower Oaks), Montgomery County, MD: The CRI Permit Manager was responsible for coordinating the wetland delineation, pre-application meeting and agency coordination for this TMDL outfall restoration project. This is an outfall restoration project is on an unnamed, intermittent tributary to Cabin John Creek, located east of Tower Oaks Boulevard, south of Preserve Parkway. The project involves restoration of approximately 998 LF of the intermittent tributary, as well as outfall stabilization, and stormwater management improvements. The proposed design includes maintaining the existing channel alignment, raising the invert, grading the floodplain, and splitting flow at the outfall at Tower Oaks Boulevard. Other activities included completing the Joint Federal State Permit Application Package for wetland and waterway impacts; completing the forest conservation exemption package; coordinating the project with the regulatory agencies, coordination with designers; request/coordinate support activities (stream/system studies, NEPA/MEPA, natural resource inventories); and obtaining environmental permit approvals.
TMDL New SWM BMP, Frederick County, MD: The CRI Permit manager and part of the design team for new SWM projects in Frederick County. Conducted wetland delineations, forest stand delineations at 13 sites. It was determined that no resources were impacted and therefore, no environmental permitting was required. Conducted in field investigation of two sites and developed concept designs. This effort included verifying base information; confirming drainage patterns and land use; identifying site constraints such as natural resources, site accessibility, and utilities; investigating downstream outfall conditions; and documenting the field investigation with photos/notes. Developed of hydrologic models, sized BMPs to meet environmental site design requirements, and reviewed plans for stormwater management BMPs. Addressed SHA/MDE comments from the concept, semifinal and final plans and incorporated modifications. Prepared PI, Semifinal, Final, and PSE design submissions. Assisted in preparing the project for advertisement.
TMDL SWM Retrofit Projects, Baltimore & Harford Counties, MD: The CRI Permit Manager was responsible for coordinating the wetland delineation, pre-application meeting and agency coordination for 12 proposed TMDL SWM retrofit projects. The main goal of the retrofits is to provide water quality management for unmanaged impervious areas under the (MS4) permit. For Baltimore County, this TMDL project proposes to retrofit 6 individual sites, either located at existing SWM facilities or areas of proposed SWM facilities, along various SHA-maintained roadways throughout the County. These roadways include the I-795 and MD 940 interchange, MD 166 at MD 372, MD 43, and I-795. For Harford County, this TMDL project proposes to retrofit 6 individual sites located at existing SWM facilities along various SHA maintained roadways throughout the County. These roadways include MD 24, US 1, MD 543, MD 152, and MD 22. The CRI Permit Manager provided a list of potential permits based on existing resources within the project area during preliminary design.
TMDL Tree Establishment at SHA ROW, Carroll County MD: This project is for the care of installed trees and the management of vegetation within TMDL tree planting sites in Carroll County. CRI conducted a desktop evaluation of 155 sites for this TMDL contract by reviewing wetland and stream data, mapped wetlands/streams, aerial imagery, wetland delineation reports, and field sketches to determine whether additional delineations or field reviews are required. CRI coordinated with SHA to finalize site list for field sketches at 24 sites. CRI provided geodatabase of sites and site inspection/selection potential wetland sketch shapefiles to delineation teams for field assessment. CRI compiled final geodatabase of wetlands and streams within 25’ of establishment site. Information was used to avoid wetland and waterway impacts so no permits would be required.
