About this file

Written by GovTribe AI · Oct 30, 2026

This file contains site plans prepared by Timothy Tracy for the Water Street Parking Garage Expansion Project in New London, Connecticut. The document provides architectural and engineering designs for the expansion of the existing Water Street Garage, which currently accommodates approximately 1,000 parking spaces and will be expanded to add roughly 250 net new parking spaces. The expansion project is directly associated with the construction of the new Coast Guard Museum, currently under development along New London's waterfront with an anticipated opening in August 2027. Construction of the garage expansion is scheduled to commence in summer 2027, with completion projected within 12 to 18 months thereafter, positioning the expanded facility to support the museum's anticipated annual visitor traffic of over 300,000 visitors.

The site plans contained in this file represent the design and engineering documentation necessary to support the outsourced controller services contract opportunity for the Water Street Parking Garage Expansion Project. These plans serve as technical specifications and visual representations of the proposed expansion scope, providing detailed layouts and site configurations that would inform project management, cost estimating, and construction scheduling for entities bidding on the controller services contract. The plans are instrumental in establishing baseline project parameters and physical requirements for the parking facility upgrade to accommodate increased demand generated by the Coast Guard Museum's opening and subsequent visitor volume.

STORM WATER MAINTENANCE PROGRAM

UPON SITE DEVELOPMENT, THERE WILL BE A NEED TO PERIODICALLY MAINTAIN STORMWATER

SYSTEMS ON THE PROPERTY. THE STORMWATER SYSTEM CONSISTS OF PIPING AND CATCH

BASINS.

IN ORDER TO ENSURE OPTIMAL PERFORMANCE OF THE SYSTEM, THE FOLLOWING STORMWATER

MAINTENANCE PROGRAM HAS BEEN ESTABLISHED. THE PROPERTY OWNER WILL BE RESPONSIBLE

FOR IMPLEMENTATION OF THIS PROGRAM.

A. CATCH BASINS/YARD DRAINS

CATCH BASINS ARE DESIGNED WITH 4-FOOT MINIMUM DEPTH SUMPS FOR THE PURPOSE OF

COLLECTING COARSE SEDIMENT. ALL CATCH BASINS SHOULD BE INSPECTED TWO TIMES PER

YEAR, TYPICALLY WHEN THE SITE IS SWEPT IN THE SPRING AFTER WINTER SANDING AND IN THE FALL AFTER ALL THE LEAVES HAVE FALLEN. SITE SWEEPING SHALL BE PROVIDED BETWEEN APRIL

15 AND MAY 15 EACH SPRING.

SEDIMENT SHOULD BE REMOVED WHEN IT EXTENDS TO WITHIN 6 INCHES OF THE OUTLET PIPE

INVERT OR NOT LESS THAN ONCE PER YEAR. CLEANOUT WITH A VACUUM TRUCK IS GENERALLY

THE BEST AND MOST CONVENIENT METHOD. THE SEDIMENT SHALL BE DISPOSED OF IN AN

APPROVED OFF-SITE LOCATION IN ACCORDANCE WITH TOWN AND STATE REQUIREMENTS.

B. PAVEMENT SWEEPING

THE PARKING AREA AND ROADWAY SHALL BE SWEPT ANNUALLY. SWEEPING SHOULD OCCUR IN

THE SPRING AFTER WINTER SANDING, BETWEEN APRIL 15 AND MAY 15.

C. FRONT-END LOADERS, BACKHOES, OR VACUUM TRUCKS CAN BE USED TO REMOVE THE

ACCUMULATED SEDIMENT FOLLOWED BY MANUAL REMOVAL OF SEDIMENT DEPOSITED AROUND

THE OUTLET CONTROL DEVICE. THE SEDIMENT SHALL BE DISPOSED OF IN AN APPROVED

OFF-SITE LOCATION IN ACCORDANCE WITH TOWN AND STATE REQUIREMENTS. THE

DISTURBED AREA SHOULD BE IMMEDIATELY SEEDED WITH APPROPRIATE GRASS SEED AND

MULCHED WITH HAY AFTER REMOVAL OPERATIONS ARE COMPLETED TO PREVENT THE OUTLET

CONTROL DEVICE FROM CLOGGING.

D. LAWN AND VEGETATED AREAS

VEGETATED COVER SHALL BE MAINTAINED ON ALL EARTH SURFACES TO MINIMIZE SOIL

EROSION. USE IF FERTILIZER SHOULD BE MINIMIZED AND APPLIED USING PRUDENT

APPLICATION PROCESSES.

E. ROOF GUTTERS

REMOVE ACCUMULATED DEBRIS AND INSPECT FOR CLOGGING AND/OR DAMAGE AT LEAST

ONCE A YEAR, TYPICALLY IN THE FALL AFTER THE LEAVES HAVE FALLEN. ANY DAMAGE SHOULD

BE REPAIRED AS REQUIRED.

F. UNDERGROUND DETENTION SYSTEMS

UNDERGROUND DETENTION SYSTEMS SHALL BE INSPECTED QUARTERLY AND SEDIMENT

SHALL BE REMOVED AS NEEDED TO ENSURE PROPER FUNCTIONING OF STRUCTURES.

AREAS OF DISTURBANCE THAT MAY BE AS A RESULT OF CLEANING SHALL BE SEEDED

AND PLANTED IN ACCORDANCE WITH THE ORIGINAL PLANTING PLAN. THESE

STRUCTURES WILL BE MAINTAINED YEARLY, OR MORE FREQUENTLY AS REQUIRED.

WASTE MATERIAL WILL BE PROPERLY DISPOSED OF OFF-SITE.

G. PROPRIETARY HYDRODYNAMIC SEPARATOR

BEFORE BEING DISCHARGED TO THE UNDERGROUND GALLERIES, STORMWATER

RUNOFF FROM THE ROADWAY AND BUILDING WILL BE DIRECTED TO A HYDRODYNAMIC

SEPARATOR. THIS STRUCTURE WILL REMOVE SUSPENDED SOLIDS, DEBRIS AND

FLOATABLES CONSTITUENTS FROM STORMWATER. OIL, SCUM, AND SEDIMENT WILL

EVENTUALLY ACCUMULATE AND CAN BE REMOVED THROUGH A MANHOLE LOCATED AT

THE TOP OF THE SEPARATOR. THIS STRUCTURE WILL BE MAINTAINED YEARLY, OR

MORE FREQUENTLY AS REQUIRED. THE UNIT SHOULD BE INSPECTED AND MAINTAINED

IN ACCORDANCE WITH THE MANUFACTURER'S SPECIFICATIONS. WASTE MATERIAL

WILL BE PROPERLY DISPOSED OF OFF THE SITE.

1. EXISTING AND PROPOSED FINISHED GRADES COMPARED TO FEMA DFIRM PANELS

09011C0501J AND 09011C0502J WITH AN ELEVATION OF 11 FEET AS MAPPED.

2. ALL VOLUMES SHOULD BE CONSIDERED APPROXIMATE.
