About this file

Written by GovTribe AI · Jun 5, 2025

The document is a set of engineering drawings for the Indian River Inlet Beach Nourishment project by the U.S. Army Corps of Engineers Philadelphia District. The project involves beach renourishment of the north beach of Indian River Inlet in Sussex County, Delaware, spanning approximately 5,000 linear feet. The beach fill aims to provide flood and coastal storm damage reduction for Delaware Seashore State Park, Route 1, and the Route 1 bridge.

The technical drawings detail the project's design specifications, including a 60-foot berm at 9.2 ft NAVD elevation with a 1V:10H slope, borrow areas in the Indian River Ebb Shoal, and cross-sectional views of the proposed beach profile. The contract will involve dredging sand from two designated borrow areas (Area A and Area B), with specific requirements for dredging sequence and depth. The project is estimated to cost between $5-10 million, with a 120-calendar day completion timeline from the Notice to Proceed, and is classified under NAICS code 237990 for Heavy and Civil Engineering Construction.

GENERAL NOTES:

1. ELEVATIONS ARE EXPRESSED IN FEET AND TENTHS OF A FOOT AND REFER TO THE NORTH AMERICAN VERTICAL DATUM (NAVD) 1988.

2. HORIZONTAL CONTROL IS REFERENCED TO THE DELAWARE STATE PLANE COORDINATE SYSTEM (NAD 1983).

3. THE CONTRACTOR SHALL STAGE AND ACCESS THE SITE FROM THE LOCATIONS SHOWN ON SHEET G-101 AND G-102. SEE SPECIFICATIONS FOR FENCING AND SIGNAGE REQUIREMENTS. SIGNAGE, FENCING, AND OTHER RELATED INSTALLATIONS MAY HAVE TO SATISFY LOCAL REGULATIONS AND/OR PROPERTY USE AGREEMENTS. OFFSET DISTANCES FROM EXISTING CONCRETE PIER COLUMNS

TO BE CONFIRMED WITH LOCAL OFFICIALS.

4. THE EXISTING SITE CONDITION SURVEYS CAN ONLY BE CONSIDERED REPRESENTATIVE OF THE CONDITIONS AT THAT TIME THEY WERE TAKEN. THE SURVEY DATA BELOW ELEVATION 5 WAS TAKEN JULY 2024. DNREC CONDUCTED AN EMERGENCY BEACH FILL PROJECT SUBSEQUENT TO THE 2024 SURVEY BEING CONDUCTED. THE SURVEY ABOVE ELEVATION 5 IS REPRESENTATIVE OF THE AS BUILT CONDITION OF THE DNREC REPAIR AND OCCURRED IN 2025. UPON RECEIPT AND ACCEPTANCE OF THE PRE CONSTRUCTION SURVEY THE TEMPLATE WILL BE REVISED. THE MHW LINE SHOWN IN THE PLAN VIEW IS BASED ON THE JULY 2024 SURVEY.

5. THE CONTRACTOR SHALL NOT DAMAGE ANY AREAS OF THE EXISTING DUNE WITHIN THE CONTRACTOR WORK LIMIT.

6. SEE SPECIFICATIONS FOR SURVEY CONTROL POINT INFORMATION.

7. THE AERIAL WAS TAKEN ON MARCH 21 2021, AND CAN ONLY BE CONSIDERED REPRESENTATIVE OF THE CONDITIONS OCCURRING AT THAT TIME. DNREC CONDUCTED AN EMERGENCY BEACHFILL PROJECT SUBSEQUENT TO THE AERIAL BEING TAKEN.

8. CONTRACTOR SHALL BE RESPONSIBLE FOR LAYING OUT THE WORK AND FIELD VERIFYING ALL MEASUREMENTS AND GRADE PRIOR TO

CONSTRUCTION.

9. DIMENSIONS AND/OR ELEVATIONS MARKED PLUS OR MINUS (+/-) ARE APPROXIMATE. THE CONTRACTOR SHALL VERIFY ACTUAL

DIMENSIONS IN THE FIELD.

10. THE CONTRACTOR SHALL MAKE HIS OWN INTERPRETATION OF THE CHARACTER AND CONDITION OF THE MATERIALS WHICH WILL BE ENCOUNTERED BETWEEN THE VIBRACORE LOCATIONS. THE CONTRACTOR, AT HIS OWN EXPENSE, MAY MAKE ADDITIONAL SURVEYS AND INVESTIGATIONS AS NECESSARY TO DETERMINE CONDITIONS WHICH WILL AFFECT THE PERFORMANCE OF THE WORK.

11. OFFSETS REFLECT A PERPENDICULAR OFFSET (90 DEGREES) FROM THE B/L LISTED AS L, (LEFT) OR R (RIGHT), UNLESS OTHERWISE

NOTED.

12. THE EXISTING STEEL SHEET PILE WALL LOCATED ALONG THE WESTERN LIMIT OF THE WORK AREA MUST BE PROTECTED FROM DAMAGE FROM EARTHMOVING EQUIPMENT DURING DUNE CONSTRUCTION. THE CONTRACTOR MUST MAINTAIN A CONSISTENT GROUND ELEVATION ON EITHER SIDE OF THE SHEET PILE WALL DURING EARTHWORK ACTIVITY TO PREVENT UNBALANCED LOADING ON THE WALL. CONTRACTOR SHALL BE RESPONSIBLE FOR DAMAGE TO INSTALLED SHEETPILE FROM DELDOT.
