Site Plans & Plan Production

Site Plans
Typical plans for residential services include:

Certified Plot Plan (CPP)
Required for all construction projects and needed to obtain building permits. A CPP is produced in addition to property staking.

Existing Conditions Plan (ECP)
Often requested by architects/property owners/builders and are the first step to any design. ECP plans are required to determine things like building setbacks, lot coverage limits, and boundary determinations, together with other detailed information necessary for proper site planning.

Septic Design Plan
Required to move, alter, repair and design an existing or new septic system. Increasing the number of bedrooms requires a septic plan for presentation to the local board of health

Site Design Plan
Shows the proposed site alterations such as grading, proposed buildings, and parking area. Often site design plans are used for permitting purposes often involving conservation commissions and zoning boards of appeals applications.

As-built Plan
Final drawings and specifications showing the as-built conditions and reflect all the additions, deletions and other changes made during the construction of the project. As-built plans are an integral part of the building construction process and required by the local building department

Land Surveying & Mapping

Land survey and mapping services utilizing the latest technology for any size project, terrain, required accuracy, or dataset. Surveying provides the critical base positional information necessary for every land or waterway oriented project. CIE surveyors are seasoned field professionals versed in a variety of techniques and tools. We invest in the latest technology and equipment that provides the most accurate, efficient and comprehensive survey data on Cape Cod including GPS, satellite, robotics, drones and 3-D laser scanners.

Uses of land survey data include:

  • Existing conditions documentation
  • Topographic map creation
  • Boundary determination
  • Construction staking required for building construction
  • As-built condition documentation

Site Feasibility Analysis

If you plan to buy, sell, build, or develop a property on Cape Cod a CIE site feasibility analysis should be your first move.

Together we’ll review your goals and objectives for the property, identifying available uses, potential restrictions, and possible permitting requirements or challenges. With thirty years of local experience with successful construction and development projects, CIE can perform a feasibility study that will save time and money, and allow you to reduce risk before you break ground.

Flood Zone Determination

Ownership and development of property within a FEMA-designated flood zone can require significant building regulations, restriction, and costly flood insurance – all of which negatively affect the value of your asset. Flood Insurance Rate Maps (FIRMs) were drawn with a fairly broad stroke using aerial survey technology and at times may include incorrect determinations for some properties; however, landowners that can document inaccuracies may apply to appeal a designation. In many cases, CIE has been able to achieve a reclassification for our clients to save them money or, in some cases alert them to misclassifications that understate flood risks.

With a land survey and elevation study on your property, we will determine and verify flood zone delineations. If we find any inaccuracies between the survey data and the FIRM maps, we can review your options with you, which may include filing a LOMA (Letter of Map Amendments) application. A LOMA officially amends the effective National Flood Insurance Program map, making it public record that a property or specific structure has been officially removed

Wetlands Permitting

Wetlands are critically important natural systems that work together to provide Cape Cod with the beautiful natural coastline that we all treasure. Salt marshes, land under the ocean, salt ponds, tidal flats, fish runs, shellfish habitat, and freshwater wetlands are components of a complex natural system important for maintaining diversity. Coastal beaches, dunes, banks and barrier beaches play a crucial role in buffering inland property against storm surge and erosion.

The Massachusetts Wetlands Protection Act protects the public assets provided by our wetlands: flood control, storm damage prevention, public or private water supply, groundwater supply, prevention of pollution, protection of fisheries and protection of land containing shellfish. Any person who wishes to “fill, dredge, remove, or alter” a wetland or a natural buffer zone must first file a Notice of Intent with the conservation commission in the city or town in which the project is to be located.

If a project is to be built within a coastal wetland, it must be built in a way that does not destroy its public value – protecting the applicant’s long term investment and the public’s right to protection from unwise and inappropriate development. Wetlands are critically important natural systems that work together to provide Cape Cod with the beautiful natural coastline that we all treasure.

Beach Nourishment

Beach nourishment typically includes adding of suitable sand to an existing beach area above the average high tide mark. The adding of sand to coastal beaches can help to protect against coastal erosion when properly permitted and implemented. It is important to consider the coastal ecosystem along the shoreline for not only the subject property but also adjacent down-drift areas that will be impacted by the natural migration of the sand when planning beach nourishment projects.

When planning a beach nourishment project it is important to consider the many environmental and legal aspects to protect the environment and the property, preserve the property owner’s rights and help protect against future litigation.

Coastal Bank Stabilization

Coastal Bank Stabilization can be accomplished by way of engineered re-enforced structures (hard solutions) or through a process of grading and/or manipulation soils and planting of vegetation (soft solutions). Erosion caused by strong coastal storms, hurricanes, flooding events, and sea-level rise for waterfront property owners can be a serious concern with drastic financial implications.

Successful implementation of a coastal bank stabilization project is highly dependent on how early action is taken.

Shoreline Armament

Shoreline armament is the practice of using physical structures to protect shorelines from coastal erosion – a complex natural process continuously reshaping our Cape Cod shoreline.

Property owners can stabilize coastal land and protect residential and commercial infrastructure by building shoreline armoring structures such as seawalls and breakwaters designed to hold back the ocean and prevent the loss of sediment.

Septic System Design

CIE provides property owners on Cape Cod with engineering services for residential septic systems that include assessments, inspections, design, construction oversight and permitting.

Wetlands Restoration & Replication

Wetland restoration is the manipulation of a former or degraded wetland’s physical, chemical, or biological characteristics to restore its natural functions. CIE designs and permits wetland replication projects such as filling and replicating wetlands or restoring illegally altered wetlands and/or wetland buffer zones.

Soil Testing (Percolation “Perc” Test)

In Massachusetts, a soil evaluation and percolation test ( ‘perc test’ ) is part of a septic system design project and required by the DEP/local board of health to determine soil suitability and the size of the leaching area. Often a percolation test is the first step in determining if a lot can be built on or if the land is being prepared for a sale. Percolation tests are also required when a septic system is enlarged or needs to be replaced.

CIE can provide a complete soil testing service for property owners that include:

  • Review of the site and possible system locations
  • Procurement of the excavation contractor (optional)
  • Filing of application and scheduling with Town Board of Health
  • On-site evaluation of soils/percolation test witnessed by Board of Health Agent

Nitrogen Mitigation & Management
Helping clients legally increase bedrooms

Some smaller residential lots in Mashpee and Falmouth may be restricted to one or two-bedroom homes because they are located within nitrogen sensitive areas.

Using our in-depth knowledge of Title 5 regulations and wastewater technology, CIE has developed a turn-key package to help property owners gain the right to add additional bedrooms in certain nitrogen sensitive areas.

CIE services can significantly increase the property values of some of these smaller properties in an environmentally responsible manner. Only certain properties can benefit from this service. Contact us to learn more.
