(1) Definitive standards for road approaches on modified access controlled highways shall be as follows:
(a) The type of approach for each parcel shall be commensurate with the present and potential land use and be based on appraisals which consider the following:
(i) Local comprehensive plans, zoning and land use ordinances.
(ii) Property covenants and/or agreements.
(iii) City or county ordinances.
(iv) The highest and best use of the property.
(v) Highest use and best use of adjoining lands.
(vi) Change in use by merger of adjoining ownerships.
(vii) All other factors bearing upon proper land use of the parcel.
(b) The type of approaches* to be considered are:
(i) Type A (residential).
(ii) Type B (farm).
(iii) Type C (special use).
(iv) Type D (commercial single 50 feet width).
(v) Type E (commercial double 30 feet width).
(c) Once established, the type, size and location of the approach may be modified by the secretary of transportation or his designee.
(d) When Type D or E approaches have been established, interim use of Type A or B approaches will be allowed.
(2) Design. The number and location of approaches on a modified access control highway shall be carefully planned to provide a safe highway compatible with present and potential land use. The following will be applied:
(a) Parcels which have access to another public road or street as well as frontage on the highway will not normally be allowed direct access to the highway.
(b) Approaches located in areas where sight limitations create undue hazard shall be relocated or closed.
(c) The number of access openings shall be held to a minimum. Access openings are limited to one approach for each parcel of land with the exception of extensive frontages where one approach is unreasonable or for Type E approaches which feature separate off and on approaches.
(d) Joint use of access approaches shall be considered, where feasible.
(e) New approaches will be considered at the time of plan adoption to prevent a physical "landlock" by reason of access taking.
(f) Existing access points not meeting the test of these rules as described in this section, will be closed.
