DC Water - System Availability Fee (S.A.F.)

As the implementation date of the DC Water System Availability Fee (S.A.F.) approaches, we wanted to provide our clients and collegues with a reminder and the anticipated fee schedules below. Initially intended to be effective June 1, 2016, the DC Water S.A.F. was delayed until January 1, 2018.

Discussions with DC Water indicate grandfathering will be limited to DCRA Construction Permit applications submittted and logged in prior to the effective date. Additionally, to be grandfathered the following conditions must be met:

  • DC Water review fee is paid.
  • Plans, specifications, etc. comply with DC Construction Codes.
  • DC Water Certificate of Approval is issued within one year of the effective date.

We anticipate a flood of applications leading up to the new year and strongly recommend submitting applications by early December ... or sooner!

Greater Potomac Golf Classic – June 9, 2017

CAS Engineering’s Jeff Robertson organizes the Greater Potomac Golf Classic benefitting the Julie Ann Robertson Cashour Memorial Fund (JARC). This annual outing has raised more than $425,000 over the past 17 years with over $153,000 distributed to multiple charities dedicated to improving the health and well-being of individuals and families affected by Neurofibromatosis (NF).

The longevity and continued success of this tournament are directly attributed to the generous support of CAS Engineering’s clients, associates, and friends. The 2017 event was the most successful and well attended yet. A full field of 144 registered golfers along with numerous sponsors and volunteers helped to raise over $50,000.

Mark your calendars now for the 18th Annual Greater Potomac Golf Classic scheduled for Friday, June 8, 2018, at Whiskey Creek Golf Club in Ijamsville, Maryland. Contact Jeff Robertson at or 301-639-3737 for additional information or to reserve your foursome.

New Pop-Back Restrictions for Row and Semi-Detached Dwellings in the District

Effective April 28, 2017, the Zoning Commission of the District of Columbia passed Order No. 14-11B, which introduced restrictions on rear additions in the R-3, R-13, R-17, R-20, and RF zones. Rear walls of additions may not extend more than 10 feet behind the furthest rear wall of any adjoining principal residential building without BZA approval. In talks with DCRA, it is believed that they will require a survey or other formal documentation submitted with building permit applications to prove compliance with this regulation.

CAS Engineering Interns – Making Us Proud!

For the past 18 years, we have routinely employed high school and college interns at CAS Engineering. It’s often been a great experience for the intern and a valuable addition to our staff. Several interns have joined us after college as “real” engineers.

We’d like to congratulate Carolina Torres and Matt Landsman. Carolina who graduated from Johns Hopkins in May with a BS in Civil Engineering and will be continuing her education at JHU in the fall. She’ll be pursuing a Master’s Degree in Engineering Management with a concentration in Environmental Systems Analysis, Economics, and Public Policy.

Matt graduated from The University of Maryland in May with an MS in Civil and Environmental Engineering. He's heading to the University of Texas this fall to pursue his PhD in Environmental Engineering. His area of concentration will be the disinfection of drinking water using microwaves as a cost-efficient method for underdeveloped regions. For nerds; his goal is to optimize nanoparticles for water treatment and eliminate disinfection byproducts ... but you knew that, right?

We wish them both much success as they continue their educations.

Minimum Wage Hike, Round 2

On July 25th Montgomery County Council Member Marc Elrich introduced a new minimum wage law. As you may recall, County Executive Ike Leggett vetoed a similar bill earlier this year. Among other changes, the new version proposes to raise the minimum wage to $15 per hour by 2020 (2022 for certain small businesses). The next round of debates should enthrall! The staff report can be viewed on the Council’s website [here].
