FIELD VERIFICATION PRIOR TO ORDERING MATERIALS.

ACTIVITIES THAT DISTURB BIRD. HABITAT, INCLUDING BUT NOT LIMITED TO CLEARING, GRUBBING, AND IMPACTS TO STRUCTURES WHERE MIGRATORY BIRDS AND BALD EAGLES MIGHT NEST, REQUIRE A NEST HABITAT SURVEY.

ACCESS FOR PROJECT SITE INGRESS/EGRESS.

WHEN INCLUDED IN THE SCOPE OF WORK, THE PURPOSE OF DEEP PLOWING THE SLOPE OR BERM OF A CHANNEL IS TO BREAK UP THE DESICCATED SOILS AND TO ELIMINATE ANY VOIDS, OR RILLING CLOSE TO THE SURFACE OF THE SLOPE OR BERM. THE CONTRACTOR WILL DEEP PLOW THE SLOPE OR BERM TO A MINIMUM DEPTH OF 2 FEET IN AREAS CONTAINING VOIDS AND/OR RILLING. IN AREAS OF VOIDS ONLY, THE SURFACE FROM WHICH THE 2 FEET DEPTH IS MEASURED WILL BE THE LEVEL OF THE SURROUNDING UNDISTURBED SOIL. IN AREAS OF RILLING, THE RILLS WILL FIRST BE KNOCKED DOWN AND LEVELED OFF. THE 2 FEET DEPTH WILL THEN BE MEASURED FROM THIS NEW SURF ACE. THE CONTRACTOR WILL DETERMINE THE MEANS AND METHODS FOR DEEP PLOWING.)

1. THE PROJECT PLANS ARE INTENDED AS A GUIDE. THE REPAIR AREA LIMITS WILL BE DETERMINED IN THE FIELD BY

THE HCfCD REPRESENTATIVE. DUE TO THE DYNAMIC CONDITIONS IN THE FIELD, PROJECT SCOPE AND QUANTITIES MAY VARY FROM THE PLANS AND/OR CROSS SECTIONS. HCFCD RESERVES THE RIGHT TO ADJUST PLANS AND

QUANTITIES AS NECESSARY. PROJECT SCOPE MAY BE ADJUSTED AS PRIORITIES CHANGE.

2. THE PURPOSE OF THE CHANNEL DESIL T IS TO RESTORE POSITIVE DRAINAGE DURING LOW FLOW CONDITIONS. UNLESS SPECIFICALLY STATED OTHERWISE, IT IS NOT THE INTENT OF THE PROJECT TO DEEPEN THE CHANNEL BEYOND ITS ORIGINAL DESIGN CONFIGURATION. EXCAVATION OF SILT SHOULD NOT UNDERMINE THE TOE OF THE SLOPE.

GEOTECHNICAL NOTES

STORM SEWER

• DESIGN AND CONSTRUCTION SHOULD ADDRESS BEDDING AND BACKFILL. WATER CONTROL, AND

TRENCHING AND SHORING CONSIDERATIONS FOR OPEN-CUT INSTALLATION. A TRENCHLESS

CONSTRUCTION CAN BE CONSIDERED FOR THE STORM SEWER WITHIN THE DOWDELL WOODS

SUBDIVISION WHICH WILL BE INSTALLED BENEATH THE EXISTING DRAINAGE DITCH. DESIGN ANO CONSTRUCTION CONSIDERATIONS FOR OPEN CUT AND TRENCHLESS CONSTRUCTION ARE PRESENTED

IN THE FOLLOWING PARAGRAPHS.

TRENCH EXCAVATION

EXCAVATION FOR THE STORM SEWER CAN EITHER BE SLOPED, IF SPACE IS AVAILABLE OR

VERTICAL. INFORMATION FOR EACH SITUATION IS PRESENTED BELOW.

SLOPED EXCAVATIONS.

• • THE OCCUPATIONAL SAFETY ANO HEALTH ADMINISTRATION (OSHA) STANDARDS (29 CFR, PART

1926.650 TO .652, SUBPART P. APPENDIX A PROVIDE FOUR OPTIONS FOR THE DESIGN OF

SLOPING AND BENCHED EXCAVATIONS. THE DESIGN OPTION 2 IS BASED ON SOIL TYPE. THREE

SOIL TYPES ARE INCLUDED IN APPENDIX A OF THE OSHA REGULATIONS. BASED ON THE OSHA

DEFINITIONS, THE ON-SITE CLAYS ARE INTERPRETED AS TYPE B SOILS, AND THE SANDS ARE

INTERPRETED AS TYPE C SOILS

• BASED ON THE OSHA STANDARDS. OPEN-CUT EXCAVATIONS ABOVE THE WATER TABLE SHOULD

BE CONSTRUCTED WITH SLOPES NO STEEPER THAN 1-VERTICAL ON 1-HORIZONTAL (45) FOR TYPE

B SOILS AND NO STEEPER THAN 1-VERTICAL ON 1.5-HORIZONTAL (34) FOR TYPE C SOILS.

FLATTER SLOPES WOULD BE NECESSARY FOR EXCAVATIONS BELOW THE WATER TABLE. IT SHOULD

BE NOTED THAT FLATTER SLOPES MIGHT BE NECESSARY DUE TO THE PRESENCE OF SILT AND

SAND, IF LOCALIZED INSTABILITIES OR SLOUGHING IS ENCOUNTERED. THE OSHA STANDARDS

REQUIRE SITE-SPECIFIC ENGINEERING DESIGN OF EXCAVATIONS GREATER THAN 20 FT.

VERTICAL EXCAVATIONS.

• VERTICAL EXCAVATIONS MAY ALSO BE CONSIDERED FOR THE UTILITY TRENCHES. THE MINIMUM

EXCAVATION WIDTH WILL DEPEND ON THE NOMINAL PIPE SIZE. VERTICAL EXCAVATIONS SHOULD

BE SHEETED AND BRACED OR CONSTRUCTED WITH THE AID OF A PREFABRICATED TRENCH BOX.

ALL VERTICAL EXCAVATIONS DEEPER THAN 5 FT REQUIRE A TRENCH SAFETY SYSTEM. THE OSHA

STANDARDS FOR EXCAVATIONS (29 CFR PART 1926.652C) PROVIDE FOUR OPTIONS FOR THE

DESIGN OF EARTH SUPPORT SYSTEMS FOR VERTICAL TRENCH EXCAVATIONS. DESIGN OPTION 1

CAN BE USED FOR TIMBER AND ALUMINUM HYDRAULIC SHORING SYSTEMS FOR EXCAVATIONS LESS THAN 20 FT. THIS DESIGN APPROACH IS BASED ON USING ONE OF THREE SOIL CLASSIFICATIONS

INCLUDED IN APPENDIX A OF THE OSHA REGULATIONS.

BEDDING ANO BACKFILL

• ITEM 430 OF THE HARRIS COUNTY SPECIFICATIONS OUTLINES REQUIREMENTS FOR CONSTRUCTION

OF UNDERGROUND UTILITIES. BEDDING ANO BACKFILL DETAILS PRESENTED IN ORDINARY PIPE BEDDING, DRAWING NO. HC430-1 IS APPLICABLE IF THE STORM SEWER IS LOCATED OUTSIDE OF THE ROADWAY. BEDDING AND BACKFILL DETAILS PRESENTED IN SPECIAL PIPE BEDDING, DRAWING

NO. HC430-2 IS APPLICABLE IF THE STORM SEWER IS CONSTRUCTED BELOW THE ROADWAY.

IF SANDS OR SIL TS ARE ENCOUNTERED, AND IF A FIRM, ORY BOTTOM IS NOT PRESENT UPON COMPLETION OF EXCAVATION, OEWATERING AND BEDDING AND BACKFILL MEETING SPECIAL PIPE

BEDDING FOR UNSTABLE SOIL CONDITIONS, AS OUTLINED IN DRAWING NO. HC430-3 MAY BE

REQUIRED.

A REPLACEMENT OUTFALL STRUCTURE WILL BE CONSTRUCTED NEAR THE BOTTOM THE CYPRESS

CREEK. HARRIS COUNTY FLOOD CONTROL DISTRICT (HCFCD) MINIMUM REQUIRED SIDE SLOPE OF

4-HORIZONTAL TO 1-VERTICAL CHANNEL IS CONSIDERED FOR THE PROPOSED OUTFALL

STRUCTURE AT THE CYPRESS CREEK. ENGINEERING ANALYSES WERE PERFORMED TO EVALUATE

THE PROPOSED CHANNEL SIDE SLOPES. OUR SLOPE STABILITY ANALYSES ARE PRESENTED IN THE

FOLLOWING REPORT SECTIONS.

EROSION CONTROL

• GEOTECHNICAL SOIL CONDITIONS, CHANNEL HYDRAULICS. AND ACTUAL FIELD CONDITIONS ARE

ESSENTIAL IN DEVELOPING A GOOD EROSION CONTROL PLAN. HOWEVER, DUE TO THE DYNAMIC

AND COMPLEX NATURE OF WATER FLOW AND THE SOIL INTERFACE, EROSION CONTROL PLANS ARE

USUALLY BASED ON EMPIRICAL RELATIONSHIPS, WATER FLOW FUNDAMENTALS. AND FIELD

EXPERIENCE.

• SIGNIFICANT SOILS EROSIONS ALONG THE SIDE SLOPES AT THE CYPRESS CREEK WERE OBSERVED

DURING OUR SITE VISIT. IT IS RECOMMENDED THAT THE SLOPES THAT DAMAGED BY SHALLOW

SLIDES. RILLS, AND GULLIES BE EXCAVATED (BENCHING TO CREATE A BETTER BOND BETWEEN NEW

FILL AND OLD FILL). THE EROSION DAMAGED AREAS SHOULD BE OVER-EXCAVATED (AT LEAST

3-FT INTO UN-DISTURBED SLOPE SOILS). REPAIR ONLY THE DAMAGED AREAS WILL RISK OF

RE-OCCURRING OF THE SLOPE EROSION. THE NEW FILL SOILS SHOULD BE PLACED AND

COMPACTED IN HORIZONTAL LIFTS OF NO MORE THAN 6 IN. AFTER COMPACTION. THE MATERIALS

SHOULD BE COMPACTED TO 95% OF THE MAXIMUM DRY DENSITY (ASTM D 698). THE MOISTURE

CONTENTS FOR BACKFILL SHOULD BE WITHIN 1% ORY TO 3% WET OF THE OPTIMUM MOISTURE

CONTENT.
