CROWN OF THE ROAD |
Represents the change in grade from the edge of the road to the center of the road. parabolic, tangential, reverse |
|
FINISH GRADE PLAN |
existing and proposed: contours, utilities, buildings, structures, stormwater drainage inlets and spot elevations.
|
|
BRICK VENEER |
shall be attached to the wall using wall ties. |
|
PERMEABILITY OF THE SOIL |
is the ability of the soil to allow water to pass through it. Low permeability= Clay High Permeability= gravel, sand. influence permeability: type of soil and compaction. not influence permeability: rainfall or shear strength |
|
FACTORS THAT IMPACT A GRADING PLAN |
1- architect design. 2- local municipality. 3- ADA. 4- utility systems. |
|
TYPES OF FOUNDATIONS |
slabs: flat land, continuous walls: can accommodate steeper slopes and piers: less invasive. |
|
MAYOR LOAD CARRIERS IN DECKS |
beams |
|
PROPER GRADING DESIGN KEY TASK |
positive drainage, all within the PL, no runoff going to the adjacent property, no grade changes within trees drip lines, do not take into account the previous use of the site. |
|
POROUS PAVING SYSTEM |
porous asphalt: better for colder climates. porous concrete: better for arid climates. precast pavers: not for heavy traffic, better for parking lots and driveways. |
|
GREYWATER SOURCES |
Good sources: showers, sinks and washing machines. Bad sources: kitchen sink and dishwashers. |
|
MIN ELEVATION POINTS IN A PLAN |
all proposed bldgs on a grading plan should have spots elevations at every corner and an elevation per floor (typ 5 spots elev) |
|
CONSTRUCTION JOINTS |
placed at any time there is a stoppage in the pouring of concrete during construction. (use Dowel bar) |
|
CONTRACTION JOINT |
used to prevent cracking of the concrete. |
|
ISOLATION/ EXPANSION JOINT |
used between two pours of concrete but involves a material that is placed between the two pours the entire depth of the slab. |
|
SOIL BEARING CAPACITY |
1- organic soils have low bearing capacity. 2- it is acceptable to remove the poor soil and replace it with soil that has a greater bearing capacity. 3- driving piles and spread footing is also acceptable. |
|
MORTAR |
a mix of water, cement, and sand. It has high compressive strength and its used to bond masonry units together. |
|
SLUMP TEST |
performed during the pouring of concrete to determine the workability of concrete. |
|
PERLOCATION TEST |
to determine the absorption rate of the soil |
|
PROCTOR TEST |
to determine the bearing capacity of the soil. |
|
ACCESSIBLE RAMP |
min w 36" min w 48" if making 180-degree turn min 60x60 if the ramp is changing direction. |
|
WORK ON SITE SEQUENCE |
protect vegetation, remove topsoil, erosion control, clearing, demo |
|
ACCESSIBLE WALKWAYS MATERIALS |
good: concrete and wood. for wildlife trail: crushed rock, pea sized gravel, bound wood chips, coarse gravel. |
|
PHYTOREMEDIATION |
PROS: aesthetically pleasing, less secondary waste, soil is usable after the treatment, less cost than mechanical treatment. Acceptable method for removing pesticides on soil. CONS: slow process than mechanical treatment, possible groundwater contamination, can't remove contaminants on deep soil. |
|
STORMWATER MANAGEMENT INFORMATION COMING FROM |
local ecologist, climate, site and local municipality. |
|
GRADING PLAN- WHEN POORLY DESIGNED |
higher cost increase flood potential increase sedimentation higher volume of runoff lower quality of storm water |
|
RAMPS |
ONE WAY- 3' MIN TWO WAY - 5' MIN 5' MIN FOR ALL RAMPS 30' MAX FOR LANDING DISTANCE MAX SLOPE 1:12 OR 8.33% |
|
INFILTRATION TRENCHES |
use when there is only a small amount of land or space shall be used for more than one thing. |
|
RETENTION BASINS
|
store water for a period of time until either infiltrates the soil or evaporates |
|
DETENTION BASINS |
permanent flood with water |
|
BENCHMARK |
REFERENCE ELEVATION IN A GIVEN LOCATION WHEN SURVEYING |
|
CONTROL POINT |
ACCURATELY SURVEYED COORDINATE LOCATION |
|
DATUM |
SYSTEM OF COORDINATE POSITIONS ON A SURFACE |
|
DECKS- POST AND BEAMS |
ALL BEAMS SHALL BE AT LEAST THE SAME WITH OF THE POST OR WIDER TO PREVENT WATER FROM GATHERING AT THE TOP OF THE POST |
|
BEST MANAGEMENT PRACTICE- LIFE SPECTANCY |
CONSTRUCTED WETLAND- 20 Y WET POND - 20 Y GRASSED SWALE AND SAND FILTERS - 20Y INFILTRATION TRENCH - IS LIKELY TO FAIL FIRST BY GEOTEXTILE CLOGGING |
|
WOOD DECKING CONSTRUCTION |
flashing shall be used when moisture builds up may be a problem. hot dipped galvanized fasteners decrease corrosion. The blunt tips of nails do not increase the possibility of corrosion. Bottom of post shall be at least 6" above grade. |
|
SOIL AND EROSION |
SILT SOILS ARE MUCH EASIER TO ERODE THAN OTHER SOILS ORGANIC SOILS ARE VERY PERMEABLE AND THEREFORE DONT ERODE AS MUCH AS SILT SOILS |
|
AEOLIAN SOILS |
SOILS ARE THOSE WHICH ARE TRANSPORTED BY WIND. |
|
ALLUVIAL SOILS |
TRANSPORTED BY STREAMS AND FORM DELTAS. |
|
COLLUVIAL SOILS |
MIXTURE OF ROCK PARTICLES AND SOIL PARTICLES THAT USUALLY ARE FOUND AT THE BASE OF SLOPES |
|
VERTISOIL |
IS A SOIL WITH A HIGH CONTENT OF EXPANSIVE CLAY |
|
WOOD NOMINAL SIZES |
1/4" SMALLER |
|
TREE REPRESENTATION AT PLANTING PLANS |
SIZE IS 2/3 OF THE MATURE TREE |
|
EROSION CONTROL MEASURES |
FOR RUNOFF: SEDIMENT BARRIERS & COARSE AGGREGATE FOR WIND: TEMPORARY SEEDING, EROSION CONTROL BLANKETS, AND MULCHING |
