Subdivision Development from the Viewpoint of Surveyors
A developer willing to construct multiple homes on a large land plot needs a subdivision. Also, a private landowner who has to independently sell the land parcels, or a city in need of sectioning its boundaries requires subdivision.
In this discussion, we shall talk about the initial processes, commencing with surveying and engineering that anticipates the subdivision project management and subdivision development in Perth.
What is termed as “Subdivision Platting?”
“Subdivision platting” indicates the legal process of dividing a large land into smaller fragments. Hence, in the surveying and engineering industry, the term is synonymously used with “subdivision development”.
The “plat” is legal itself since it is an officially approved and recorded drawing depicting the land split layout, subsurface utilities as well as access points.
Who Should Need A Subdivision Plat?
The private landowners and land developers of Perth usually request for a subdivision plat, since they are interested in dividing their land into smaller land parcels for developing either commercial or residential properties.
These are the steps, the surveyors and engineers take up for completing the associated deliverables with the subdivision project management.
Step 1 – The Initial Survey
There might be prior-existing documents that describe the project site, normally a project commences under the guidance of surveyors visiting the land, as well as obtaining additional information exact on the utilities’ and locations’ corners.
This current data is most necessary for informing proceeding parties, like Computer Aided Designs (CAD), specialists and engineers creating exhibits and plans for the dimensions of the site lot, road utilities, building lines, water drainage and a lot more.
The registered land surveyors work closely work with CAD specialists for obtaining specifics as needed by the specialist since they need more information on or any other unique details meant for this site.
Step 2 – The Draft Plat Exhibit and Preliminary Constriction Plans
The CAD specialist, under the Registered Land Surveyor’s supervision, interprets the survey data and makes use of specific computer software for preparing a base drawing, which is termed a preliminary plat exhibit.
The draft plat exhibit will be outlining the property line, topography and conditions.
The engineer, simultaneously even derives the information from the initial survey for creating the preliminary construction plans, which are termed as preliminary engineering plans.
The construction plan addresses the infrastructure design, which comprises grading, stormwater damage, road utilities and more.
Step 3 – Country and City Submissions As Well As Revisions
As soon as the draft plan exhibit and the preliminary construction plans are completed and are ready, then they must be submitted together to Perth’s planning and zoning department for being reviewed, getting feedbacks and revisions.
Once city planning and zoning approve the documents, then the documents are sent on to the County’s planning and zoning department for the same need of reviewing, feedback and revisions.
Now, when the country planning and zoning, the documents are the last stop to be reviewed by the City Council.
Step 4 – The Final Plat and Engineering Plans
When all the issues as recognized by City and Country departments have been successfully addressed, then the final phase is initiated. In the final phase, these documents are finalized into a final plat and engineering plans.
Before submitting for final approval, the Land Surveyor signs the final plat. The final plat and plans, as the preliminary documents are again submitted through the same 3 steps reviewing process. Once the final plat and plans are approved, this time the governing entity will be signing off on the final plat, inferring the plat’s final approval along with the final construction plans.
The Professional Engineer finally signs the final construction plans which the governing entities had approved. At this point, the developer could take the construction plans and go for bidding, by allowing different contractors to apply for the very work.
Subdivision Project Management entails a series of legal steps, and the vital part is surveying for subdivision, so they are quickly approved. Hence, it is a necessity that you have to hire a Registered Land Surveyor for surveying the complete subdivision of land.
