INTRODUCTION
The Park Development Division (PDD) of Maryland National Capital Park & Planning Commission (M‐
NCPPC) has engaged RRMM Architects and our consultant team to develop the Program of Requirements
(POR), Scope of Work and schematic design level bridging documents for a design build RFP for a
proposed recreational pool, bathhouse and supporting sitework at Little Bennett Campground near
Clarksburg in Montgomery County, MD.

The design of the new pool and bathhouse shall meet all code requirements including:
‐ Current M‐NCPPC Park Design Guidelines
‐ Code of Maryland Regulations (COMAR)
‐ 2010 ADA Standards for Accessible Design
‐ Montgomery Parks ADA Compliance Manual Version 02 / 2019
‐ International Building Code 2018
‐ Code of Montgomery County Regulations (COMCOR) Chapter 51 Swimming Pools

‐ The site is served by an existing 10” diameter water line which runs near the planned pool and
bathhouse location. It has been reported by campground staff that the line has adequate spare capacity
to support the bathhouse. The filling of the pool and make‐up water requirements will be coordinated by
the design team through the bridging document process.
‐ The site does have an existing septic system. It has been reported by campground staff that the septic
system is old and does not have adequate spare capacity to serve the new bathhouse. (Requires further
study.)
‐ The site is served by an existing 200‐amp single phase 120/240 service in a large CT cabinet with a
single‐phase meter on the outside and a panel inside. It has been reported by staff that the 200‐amp
service only serves the jumping pillow.
‐ The parking area is existing to remain and does not include site lighting.
‐ The project does not include any modifications or additions to the site lighting serving the campground.
‐ Any lighting provided at the pool will be included with the pool design and the power requirements will
be identified in the electrical design.
‐ Per COMCOR 51.00.01.03.B.1 the fence surrounding the pool must be a minimum of 72” in height.
‐ MNCPPC would like the roof to be ready to receive future solar panels.

OCCUPANCY AND PLUMBING FIXTURE CALCULATIONS
Assume all water is 5’ deep or less.
Assume 1,500 SF of water and 1,785 SF of deck as shown below.
Note: The approximate pool size shall be revised to 29’x60’ – 4’ wider than shown below and in the
Bridging Documents. The SWM features were designed to accommodate the larger pool footprint.

Three separate codes potentially govern this project – COMCOR, IBC & COMAR. Washington Suburban
Sanitary Commission (WSSC) does not have any amendments altering what other codes require to
calculate the number of fixtures required.

MNCPPC will limit the occupancy of this facility to 126 people at all times.

Note: DPS adopts the WSSC Plumbing and Fuel Gas Code. In addition to the requirements listed below,
the project must adhere to the requirements of WSSC. Refer to the Bridging Documents for the most
current plumbing fixture code analysis.
