Background
You are retained by an elderly client who wishes to subdivide and sell a parcel of approximately 32 acres. The parcel is located approximately 6 miles east of the city of Elko in Elko County. Your client has already been in contact with the Director of Planning and Zoning in the Community Development Department. As the result of that meeting, your client has been encouraged to subdivide using a parcel map.
Your client has asked you as a professional land surveyor to look into the matter and advise him of what needs to be done to subdivide his property with a parcel map.
Your client wishes to partially develop each of the four parcels with road access; a water well; and Onsite Septic Disposal System; and a minimum of site grading at the house site.
Resources:
1.You have access to a recent boundary survey of the parent parcel. The result of this survey is found in “Lab5_Survey”.2.A topographic survey with 2 foot contours is available for this project. This file is entitled “Lab5_Topo” found in Course Materials.3.You will find the Elko County Parcel Map Application at the following Link: http://www.elkocountynv.net; Under the drop down menu
‘Departments’– Select Community; Select Planning and Zoning; Select Forms; Select Parcel Map Application.
4.You will find the Elko County Code on Parcel Maps and Survey at the following Link:
http://www.elkocountynv.net; Under the drop down menu ‘Departments’– Select Community; Select Planning and Zoning; Select Subdivisions; click on the link to our codifiers. On the Sterline Codifiers, Inc. site select Title 5 Subdivision Regulations on the left side of the page. Select Chapter 2 Parcel Maps.
5. Assumptions
a. All adjoiners are known and the recent boundary survey has taken their interests in account. There are no unresolved boundary or title issues. Your record research indicates that your client has clear title to the parcel. Property taxes are current on the parent parcel.
b. This is a green development as it will involve a minimum of grading. While there is one steep grade on the parcel, you will put no development there. You will not alter any drainage patterns; no wetlands exist; parcel lies outside any flood zone; no large trees on parcel; does not involve any archaeological or historic areas.
c. The parcel is bare land with its original vegetative cover.
d. A 60 foot road easement is found on the east, west, and south sides of the parcel. The north side of the parcel abuts existing improved parcels and has no road easement. The west side of the parcel has a 60 foot road easement, however a portion of the easement is found on a steep slope and would be very expensive to develop. Photo 5 shows this steep slope along the power line looking north. While the roads elsewhere have been roughed out with a bulldozer; they are unimproved and cannot be considered all-weather at this point. You can assume access to the roads from an all weather road to the developed parcels to the north and an all weather access road to the south boundary.
You should assume that all road frontage on the parcel is unimproved and would involve significant expense to improve. Therefore your design should minimize the road length to be improved.
e. No public infrastructure is available other than power and telephone. NV Energy has an easement along the West side of the parcel. Power cannot be delivered through a parcel unless the parcel borders the existing power line. NV Energy will locate poles along dedicated road easements. In other words, NV Energy will not cross a neighboring parcel to service your parcel. The developer must pay for power infrastructure. Transformers and the drop from the existing line a distance of less than 100 feet costs approximately $5000. A drop of 300 feet would cost approximately $10,000. The improvements on the parcels need to be located to minimize the cost of power infrastructure. All parcels will require a private well and onsite Septic Disposal System.
f.The location of Well and Onsite Septic Disposal Systems are regulated by the State ofNevada. The regulations are found in the Nevada Administrative Code Chapter 444 Sanitation.Location of structures is found in NAC 444.792.
6.Lab 5 Submission
The purpose of this lab is not to require you to submit a finished parcel map application and parcel map. This is a significant undertaking which lies outside of the reasonable time that you and I have to do this course.
What I expect is a package consisting of:
1.A written narrative.2.Four plot plans (one for each lot).3.A concept map showing the division of the parcel into four parcels.
Narrative
The narrative should list and explain those issues that you need to discuss with your client before you move forward. All that has happened to this point is the survey of the parent parcel. You are preparing to meet with your client to discuss moving ahead with the project. This list can be those items needed to complete the parcel map application; items of great expense in the development that the owner should know about; and an explanation of your concept for the land division.
Plot Plans
These drawings do not have to be a CAD Drawings although CAD drawings in pdf format will be accepted. Each one can simply be placed on an 8 ½ x 11” sheet of bond paper with 1” margins. Show the boundaries of the each parcel at scale. For each parcel show the road access; location of a typical three bedroom house; the location of the well, septic tank, and 100 feet of leaching field. Also show the location of an alternative field should the system fail. All of these proposed structures have to be located in feet from each other and the boundary of each parcel.
Note: The actual location of a leaching field is found by performing a percolation test based on the rules given by the State of Nevada per the NAC
444.In the narrative, you will wish to inform your client that your trial locations have to beproved up by percolation tests.
Concept Map
Prepare a simple CAD Drawing to scale on 8 ½ x 11 media. This drawing does not have to show all of the detail on your plot plans. Just enough information to show your plan on how to break the parent parcel into four lots, generally where the structure is to be placed and the road access. Since this is a concept drawing you have some latitude on how to present this information.
I realize that you do not have access to this site, nor have you conducted the survey of the parcel. However, this assignment is directed toward asking you to consider the problems associated with a Parcel Map. Please put those issues that bother you or that are unknown into the narrative you wish to discuss with your client.
Note: All drawings must be submitted to the drop box in pdf format.
