SITE INVENTORY

  • Key Information on Parcel Size & Shape:

    • Geographical Coordinates: IN 04°28'43" W, SO1'27'34" W, S0035'20" W, etc.

    • Various Length Measurements in feet such as 300.05', 244.51', etc.

EXAMPLES OF SIZE AND SHAPE

  • Properties of Various Areas:

    • Public, Service, Semi-Public, Private Zones

  • Ground Floor Information:

    • 6 units in Ground Floor (not specified type)

    • 14 units in Upper Floor (not specified type)

EXISTING PROBLEMS IN SITE ANALYSIS

  • Average temperature recorded at the site: 31.8 °C

  • High temperature recorded: 33 °C

  • Low temperature recorded: 25 °C

  • Average rainfall: 168.31 mm with approximately 9 rainy days/month.

  • Noted issues with recurrent flooding in Dukuh Atas during rainy seasons.

    • Flood events occurred in December 2017 and September 2020 with heights above 1 meter.

    • Causes of flooding: Non-functioning water pumps draining to the Ciliwung River & excessive rainwater discharge.

WIND DATA

  • Strongest winds originate from the west

  • Reporting on wind velocities provided (e.g., 10 km/h, 10 to 15 km/h).

HUMIDITY DATA

  • Recurrent high humidity through the year, with September as least humid month (61.6%) and February as most humid month (76%).

TOPOGRAPHICAL ANALYSIS OF SITE

  • Key Components:

    • Elevation

    • Slope and Aspect

    • Contour Maps as primary source of topographical information

  • Contour Map Reading:

    • A contour represents a line of equal elevation on the ground surface.

    • Contour lines demonstrate steepness; closer lines indicate steeper terrain.

    • Vi and V-shapes indicate ridges or valleys.

EXTREME TOPOGRAPHY ISSUES

  • Cut-and-Fill Techniques:

    • A method to create a level plinth on sloping sites for construction.

    • Spoil from cuts reserved to aid leveling lower areas.

RETAINING WALL CONSIDERATIONS

  • Design implications for retaining walls on sloped terrain due to forces exerted by surrounding soil.

  • Water-proofing is crucial in design stages.

NATURAL HAZARDS

  • Earthquake Zones:

    • According to SNI 1726:2012, a seismic hazard map must be referenced for building safety.

    • Building should account for seismic response spectra defining construction methods in earthquake-prone areas.

  • Flood Vulnerability:

    • Potential for flood damage should inform site planning decisions, usage classifications, and structural integrity.

CULTURAL ATTRIBUTES

  • Landuse Factors:

    • Landuse regulations and zoning must consider property values and public infrastructure impacts.

    • Aesthetic and sensory factors (e.g., visibility, noise, odor) are important.

  • Perception and Visibility:

    • Importance of surroundings on human perception; visual elements profoundly affect site planning decisions.

RELEVANT EXAMPLES

  • Tsunami Hazard Analysis:

    • Potential flood impacts dictate necessary precautions in urban planning, especially in coastal areas.

    • Zones defined by elevation and estimated tsunami height are critical for safe site development.

  • Cultural Landmarks:

    • Enhancing views for historical or scenic spots increases the sense of place and site value.
