Floodwaters close down Shen Lake Drive just east of the Port Republic Road intersection during rainstorms last June. County officials began looking at ways to mitigate flooding in the Lake Shenandoah watershed after last year’s flooding.

HARRISONBURG — The Rockingham County Board of Supervisors is seeking public comment regarding the creation of the Lake Shenandoah Stormwater Control Authority during its July 17 meeting.

The authority was proposed due to properties within the authority area being subject to urban flooding for several years. Property and structural damage occur frequently, with recent years having multiple damaging runoff events, according to the county.

After an extensive study by county staff, engineering consultants and a citizen stormwater advisory committee, it was determined that Rockingham County government should implement improvements to the capacity and function of stormwater infrastructure within this area.

The authority will encompass all areas within the watershed of Lake Shenandoah, including: Barrington Subdivision, Briarcrest Subdivision, Bridlewood Subdivision, Chestnut Ridge Subdivision, Congers Creek Subdivision, Crescent Ridge Subdivision, Cullison Creek Subdivision, Hamlet Hill Estates, Highland Park Subdivision, Kentshire Subdivision, Lake Pointe Subdivision, Lake Pointe Village Subdivision, Lake View Golf Course, Lakewood Subdivision, Massanetta Springs Conference Center, Massanetta Springs Cottage Community, Preston Lake Subdivision, Quarles Business Park, Spring Oaks Subdivision, Sunnyside Retirement Community, Taylor Grove Developments I and II, Taylor Spring Subdivision, Town and Country Landing and Wellstone Subdivision.

The northern boundary is set by Harrisonburg/Rockingham County line with approximately 0.73 miles of boundary on the southwest side of Spotswood Trail and roughly 0.34 miles on the northeast side of Spotswood Trail.

A list of all tax parcels included in the authority are available on Rockingham County’s website and at County Administrator Stephen King’s office at 20 E. Gay St.

The authority board will be comprised of Supervisors Pablo Cuevas, Sallie Wolfe-Garrison, Rick Chandler, Bill Kyger and Mike Breeden.

Preliminary estimates of capital costs were stated to be $3.16 million, but it is a “rough” estimate, according to the advertisement. The amount of capital costs will depend on numerous factors that have not been determined by the board of the authority after consultation with engineers.

No determination has been made concerning when and how fees will be assessed, but fees will likely be related to the amount of impervious area on each property, according to the county’s website.

Further engineering analysis will be conducted to determine a cost-effective method for improvements to the stormwater system. A combination of new detention facilities and increased capacity in ditches and pipes will also be evaluated.

Exact locations for improvements have not been finalized at this time, but will be made publicly once determined by the county.

A public hearing will be held at 6 p.m. on July 17 during the regular Board of Supervisors meeting.

Rockingham County staff held a work session in April to further discuss stormwater management after a presentation on recommendations was given March 13.

Lisa Perry, the environmental manager for the county, presented recommendations to the board that the stormwater management committee had made.

The committee, formed in August following significant flooding across the county, held five meetings.

The committee came up with five recommendations to better address stormwater management, including the county’s role in flood mitigation and stormwater management; problems in the Lake Shenandoah drainage area; funding mechanisms for future improvements; and higher standards.

The committee found that current regulations are more comprehensive than past standards.

Perry said there were four procedures to identify action areas, such as reviewing problems that may arise in the future and establishing a separate fund.

Perry said in April that there were different ways the county could go about allocating funding, such as grant funding, the Virginia Department of Transportation revenue sharing or funding from the county’s general fund, which the committee recommended.
